possible GT28 set-up

[MKIIIGOLFGTI]

alright i'm a BT noob so expect alot of dumb questions.

I'm selling/sold alot of parts to start putting together money to piece together i big turbo kit for the TT. Should only be another month or so till fundage is around where it needs to be. So with that said i need some help from you guys:smile:

I'm looking to get more power without the need for rods. Bunnylove told me to look into getting a T28. From what i have read this seems to put me around my goal of 250awhp. So this is what i'm looking at

Gt2871r
Exhaust manifold
440cc injectors
injector spacers
4bar fpr
FMIC
Mod my current dp or make a new one
Turbo inlet pipe
MBC
some form of tuning software

Any input would be great!

[BUNNYLOVE]

Your injectors will depend on the tune most likely. I don't really know whats available for tuning (unitronic?) but its pretty much the most important part.
I think it'll be a good setup for you.

[VRsuper6]

unitronic is good, they tune for 380cc injectors with their most common software. theres a kid in canadaigua with a gt28 on unitronic in an A4

[meatwad!!]

if you only want like 250hp..

get chipped and get a meth kit

you can push 300hp or so on stock rods

[30r_logik]

no.no.no.

www.pagparts.com or pm passatg60 on vwvortex. he can piece a kit for ya, his hardware is top notch along with the eurodyne sw( what i run)

380's will be too small.

i'd get the 630's with a gt3071r and be right around 300awhp, hell you could prolly do 300whp with just a 2871r. get a t3 flanged turbo aswell.

I'll prolly get some parts from pag but the bulk of my purchase will be used.

Why should i use 630's? everyone keeps saying that but is it because it leaves room for me to grow? I really dont see my motor handling 300awhp on stock rods. And internal engine work isnt happening this year. I daily drive the car.


Also i can get a gt2871r/t25 flange for $500, only problem is its external wg.

[meatwad!!]

dont forget boostfactory.com

[MKIIIGOLFGTI]

^thanks rob^

turbo- prolly from vortex
manifold- ebay cast
coolant/oil lines-pagparts
fmic-ebay
injectors-pagparts
mbc-ebay

[MKIIIGOLFGTI]

woohooo! already rounding up some parts!

FMIC and piping kit ordered.

[evolveVW]

what FMIC did you get? Have to be watchful of the ebay ones.

I agree, 380s might be a bit small. Leaning out is the last thing you need.

I've heard good things about Unitronic, and would probably go with them if I needed a 1.8t chip.

Exactly which cast manifold?? You get what you pay for in this case, if you cheap out you could get one that will crack, warp, etc. There are a few good quality log manifolds out there.

A GT28 should be good for 300hp if you squeeze everything out of it. A T25 flange is a mistake, then you have to swap everything if you go bigger at some point. A K04 could get you to your desired power, and have no chance of rod damage, for the most part.

[MKIIIGOLFGTI]

cx racing fmic kit(been reviewed on vortex) So i should be ok with it.

From what i have read 440s are enough for what i'm after.

manifold is undecided....again this is a budget build, but i know all about low quality manifolds.

People are saying a gt2871r is good for close to 400hp. Obviously this is more then i need. Mainly it will give me the lag so i wont have a harsh rod snapping torque spike. This will prolly see around 15psi till internal work can happen(prolly next winter). Which should put me around 230-240 whp.

Unitronics is just to expensive! i mean damn $900! if a revo 440 file is cheaper i will be dealing with revo once again. Plus i can drive there as opposed to sending my ecu out. Remember i daily drive this car....downtime needs to be at minimum. And i'm not trying to squeeze all the power i can out of this.

did i mention i have no life and have been reading the 1.8t forum sence 10:30pm? haha

again guys that a ton for all the advice so far....keep it up guys! i really appreciate it....

even you see i'm doing something wrong point me in the right direction

[MKIIIGOLFGTI]

A K04 could get you to your desired power, and have no chance of rod damage


The reason i dont want to go this route is....

A. It will end up costing almost as much to just go BT
B. Once i have this set-up the only thing to hold me back fromt a bigger turbo/more boost would be injectors/rods/tune.

I dont want to do all the work for a k04 and be near maxed out for the numbers i want.

[meatwad!!]

revo sucks for BT files. period.

[MKIIIGOLFGTI]

revo sucks for BT files. period.

you hate the local revo dealer....and your jetta was stock? so why the revo hate? I loved my revo flash to say the least. Not to mention a revo tuned 2871r made 340ish whp on a t28rs file.

[BUNNYLOVE]

Your almost always better going with larger injectors if you can get a tune for them. I would look into a T3 flanged turbo for growing room, it would make switching to a GT30, etc much easier.

[meatwad!!]

a t28rs file?
yeah, my jetta is stock, and prolly will always be. for the amount it costs to BT my car.. i can build a mk1 thats faster/more fun

[MKIIIGOLFGTI]

True on the mk1

the guys were using REVO 440 bt file for the gt28rs....revo doesnt currently have a file specifically for the 2871r

[evolveVW]

I'm just not a fan of Revo in general..

[MKIIIGOLFGTI]

So i just got this email from Revotechnik.....

These are the required hardware for stage 3 software
Garrett GT28RS with .86 a/r exhaust housing
high flow exhaust manifold or header for Garrett turbo
turbo back exhaust including a downpipe of 2.5-3.0 diameterHave!
high flow cat or test pipeHave!
front mount i/c with capacity for 350+hpsHave!
MAF housing with 70mm (vr6/225tt)
440cc bosch "greentop" injectors at stock 3 bar of fuel pressure or 380cc 225TT or equivalent injectors at 4 bar of fuel pressure
These are the recommended items:
cold air intake from MAF to front of carHave!
high pressure DV - recirculating, not dumping into the atmosphereHave!
high performance clutch capable of handing 350+ lb.ft of torque
sps select plus

This is awesome! and going to be cheaper then i thought. I'm getting the hook up on a tune, and i already have some of the items listed. Hitting auburn scrap yard tomarrow for the vr maf housing!

Revo has a very poor BT file with minimal updates/improvements since released ~5 years a go.

For a daily I'd forget a budget build software is the last place I'd skimp....its the life blood of the car when it sucks you'll need a new daily.

Unitronic/Eurodyne are the only two at this time listing to the market.

a
no bumpy idle....pulls hard? and....its revo.

From what i got out of that thread is. Revo has a conservative timing...dont see how that bad aside from a little less overall power?Pops on decell.....we was told how to fix it. For $350 in savings i would get from going with revo....i can live with that.

$900 is retarded. **** even eurodyne is only $700.
This isnt a car that i'm going to toss on the rollers every month and see what i can get out of it. Its not going to see more then 15psi for the next year.

[BUNNYLOVE]

You get what you pay for in most cases. Why doesn't it idle right and why can't they fix that with the tune? Pop on decel... I know how to fix that in the tune why don't they? Makes you wonder.

[VWTUNING]

The last BT MK4 1.8T I helped with had idle issues, REVO's recomendation was to run with no MAF. That type of logic/customer service scares me.

Unitronic has had some really good reviews, thats who I would personally go with. Then again I think I would rather move out of my parents than go BT... :laugh:

[RichB]

I think Stu makes a very good point.

As well, what if that lumpy/poor idle means a no start on a cold winter morning when you need to go to work? or leaves you stuck somewhere else at some other time or winds up with the cops pulling you over and using as a excuse the backfires on decel which costs you $$$ in time/tickets/hassle?

From what I've read over the past few years, Unitronic is the only company out that that I know of that is currently active (i.e. updating, releasing/developing SW, working with customers, answer questions) in the 1.8T big turbo. The other "big three" (GIAC, REVO, APR) have moved on to other motors, consider the 1.8T done and are not interested in spending any more time/money on it.

If you can make REVO BT SW work reliably for you, thats great. Its reputation in general though is not that... and I think all that folks are trying to do is point out those potential risks with using Revo BT SW. I'm not saying Unitronic is perfect either, but they are at least still at it. You should consider that while it may cost more now, if REVO is going to cost you more long term, is it really a good deal??? A question that you need to weigh the risks/benefits of and then go from there.

FWIW - I have no "issues" with REVO or any REVO dealer. MY 1.8T is GIAC chipped.

[MKIIIGOLFGTI]

My point is you cant follow 90% of whats on vortex.....most people say something sucks without even ever owning it/trying it.

personally i have had 2 cars chipped. One revo and one apr

most people think APR is the cats balls...but i on the other hand hate it and wish i had revo insted. From what i have experienced Revo is fantastic! when it comes to BT it might be a different story.

Uni is great for those that are trying to squeeze everything out of there set up. I will never spool that turbo to its potential therfore i cant see spending almost 1k for a base tune. Like i said a ton of people swear by tapp/eurodyne aswell and they are $300 cheaper then Unitronic. Why is there **** so expensive? overpriced i say. Maybe later on down the road when i build my block i'll look into unitronic or eurodyne but right now its just not going to happen.

Dont take this wrong guys i appreciate your input....really i do.

[MKIIIGOLFGTI]

Then again I think I would rather move out of my parents than go BT... :laugh:

:laugh: smart ass

[kabinotar]

Not trying to argue, but if you plan on building it more later. Why spend twice on software. I can see where you're coming from with the experience and what not. But, with so many good reviews, and the possibility of you upgrading more in the future to where you might want to switch tuners, it just seems to make sense to go with the tuner for future upgrades in the first place.

All my opinion of course.

[MKIIIGOLFGTI]

Right but i can just sell my ecu later... This really would be much much later. Who knows if unitronic by then wont end up like apr/revo/giac.

[MKIIIGOLFGTI]

just cause.....

630cc injectors and unitronic software and you will never have to worry about fueling again... or MAF's which are expensive... I mean really... if your MAF takes a crap=you're screwed if you want more power=your screwed if what everybody says/ experienced with REVO BT software is true=you're screwed...

Easy Choice! ... you know what? I would rather save the money I would have spent on the GT28RS and buy a cxracing ebay turbo and have unitronic software than Use an expensive ass turbo and the cheaper software... :-P

[POSgti]

Another thing... I used a CXracing ebay turbo for 2 years making roughly 300 hp on my ABA and even more torque. that was a smaller turbo ( .48 ar turbine .42 ar compressor pushing out 20 psi every single day.. I must say, I was impressed..

[BUNNYLOVE]

Thats a good example? So with the 440cc tune it runs great with an adjustable fpr, bigger 550cc injectors and lemmiwinks adjustments..

[MKIIIGOLFGTI]

If you check his posts, they are from hawii and have done great with revo. The reason i posted that thread is because look what he did using a revo 440 file. he is using bigger injectors/bigger turbo and it still runs fine with just a little tweaking.

[BUNNYLOVE]

I know who he is from years back and he knows his stuff. Its still a bad example.

I agree with POSgti and everybody else. The tune is the most important part and not the place to skimp.

[MKIIIGOLFGTI]

woot woot fmic is here!

Eric i dont think i can trust this turbo....its way to cheap....to be good.

[MIdub]

if you want cheap turbo, look into the holset hy35 or hx35's can be had on ebay for cheap and are rebuildable... the hy would prob be perfect since it has a smaller hotside than the hx... The money you save on that i would go with the 630 and uni 630 maffless file... no more mafs to deal with and a better tune overall.

[MIdub]

thats my plan for my 1.8t corrado at some point... and the holsets are t3 flanged

[MKIIIGOLFGTI]

if that cx racing turbo is any good i could afford a unitronic tune...but its looking more and more like revo will be the way i go.

[MKIIIGOLFGTI]

ATP turbo inlet pipe ordered.

[POSgti]

Hey Ryan, Sorry I could not return your text, I got rid of texting for awhile.... Yes, my CX racing turbo worked great.. All I can tell you is my experience. I would do everything the same if I did it again. I saved 500$ there alone.. haha..... My personal vote.. is go with unitronic. Gene has it on his car along with a cxracing turbo and it runs fantastic, like factory, its great. well like factory but way. way. way. faster. His car pulls like a b*stard. Let me know if you have any more questions.

[MKIIIGOLFGTI]

alright...turbo and manifold ordered....what am i getting myself into!

[MKIIIGOLFGTI]

First sign......



That CX Racing is an honest good company.

An error accured when i ordered everything and the invoice said i ordered a T3 flanged manifold. So i get a call today from CX Racing asking if i want the T3 manifold or the T25/T28 flanged manifold to match my turbo. All is taken care of and my turbo and manifold will be shipped out tomarrow! Really surprising to see that out of a company...especially in the automotive community.

[MKIIIGOLFGTI]

Turbo and manifold arrived!

now for a little trouble.....

I ordered injectors off Pat@pittsoundworks almost a month ago and still havent recieved sh*t. He hasnt answered a single pm either.

Also ordered a atp turbo inlet pipe off another vortex member and havent recieved it. Atleast he is keeping in contact.

[poops]

im gonna keep this brief. i dont have a TT, i have an 03 gti with stock rods, gt28 440 injectors and blah blah... i bought the car off vortex and broke a rod after 4 days without beating the car at all... the rods on the stock motor for the gti can really only hndle around 350-400hp. The guy i bought it from had a revo stage 3+ chip and a couple days before i bought it he said that it was going past the 25 psi it wastuned to and prolly into the 30-35psi range. find out what the stock rods on that motor are hp capable of and do the math. its MUCH easier to buy a set of IE rods and drop them in than to do an engie rebuild/buy like im doing right now. i broke a rod doing 65 mph on 690 on cruise, i hadnt boosted the turbo past 15-20psi because i was afraid of breakin S. so do the math, 1psi= 10hp + stock HP= not blowing up. yeah. if anyone has xperience with an mk4 1.8t engine swap id love to have you come help rewire my car. id help you with any future projects in any way that i could. i just want to get the car i spent 12k on back on the road so i can get out of the 89 honda crx that im driving now(although im greatful to have it). hugs and kisses on the cheek!:confused:

(not to poke fun at all)

[poops]

i had 2 holes punched in my shortblock from the #1 rod... so i bought a new shortblock and had to pull the engine and rebuild it. SOOOO im rewiring everything after the build to swap the old with the new.. i DONT have a bentley but my dads buddy owns a shop with some insane online database with ALL car manuals so im hoping that helps, but like i said, if anyone wants to come out to auburn in the next few weeks for 1-2, 4-5 hour days id be glad to cough up a bit of cash/help you with your project, whatevs. i dont know everything about cars but im eager to learn and ill hold the light for ya or whatever. thanks!:laugh:smile:

[meatwad!!]

its really a pretty straight forward harness.if you took it out .. you should have no problems putting it back in..send me a pm i could prolly stop out sometime...

You're still not specifying what is making you rewire anything. All you need to do is swap the block.

most all parts in....although some may be going back....I kinda want a 50trim :(

[poops]

do me a favor! dont seek out 300whp without replacing rods! come check out my smashed short block in auburn and youll see why!:embarrassed:
