So what all consist of this build? My buddy has a 01' 1.8T flashed with GIAC-X+ software, intake, and GHL turbo back 2.5'exhaust and it's estimated somewhere at about 195-200hp. He wants to make high 3s. Should he go with the GT28R or the GT28RS? Maybe the GT3071R?

I am happy with a 400+ hp jetta but if I could do it all over again I would probably go with a GT28RS. More that 300hp is pretty pointless becuase of traction, and with a smaller turbo you can dig into some of those lower RPM's. Don't get me wrong, from a role over 30 MPH and it's a great turbo to have but you have to be past 4000 rpms to even utilize it. After driving both a GT28rs and my GT3076R I would go with the smaller, unless your planning on differential work and tracking the car.

can you tell me where you got that grill with that red and white badge it looks so sick i cant find it anywhere. I was thinkin you bought the grill and then stuck the badge on but it looks sick.. i got an 04 1.8t

[knifesbatsnewtats]

Its a Kamei grill

wow buddy my stock 9000 gets up to 135 no problem theres something wrong with your setup

[knifesbatsnewtats]

uhh I don't have any problem either. Its a 5th gear pull with no prior boost build. No problems here.

@knifesbatsnewtats  hello dude...have you ever heard about the GT2871R?? please tell me because i'm planing to get this one,.... is smaller that the GT3076R.... for sure....

@tplayer100 Need? Maybe not right away. Many people have used bigger turbos than that on stock engines, but ran low boost. APR uses that turbo quite successfully on stock engines.

Will you want rods? Yes. The low end torque that a gt28rs creates is what will kill your rods. Rods are relatively inexpensive, unless you have a shop install them. You can do rods for $400. A shop will cost you $1500. But, $1500 is FAR cheaper than replacing an engine that slings a rod out of the block.

@qzbikowski do you think i would need new connecting rods for a gt28rs turbo and software or will stock internals be able handle the 300- 320 whp?

[koglowa]

a testament to vw power, rods and bolt ons for 416whp! if you could message me a list of mods, that'd be great. i'm most likely gonna aim for 320whp with a solid torque curve. already at 20psi but the turbo hates it, i need supporting mods.

[kolesztar]

how much would you say tuning cost overall?

[juliangamboa69]

@knifesbatsnewtats PLease ...Please help me dude.... i'm planing get a biger turbo for my 05 Gti 1.8t and i decide GT28RS, the kit come bold on for my car.... do you really thing that i will need to chip or flash my ECU?? what other mods do you recomend?? i already have Front intercooler and CAI, full exaust. please write me..thanks

[CantFaze]

@knifesbatsnewtats yea dude the 5th gear on these cars is impressive especially with your setup.. i have revo software , turbosmart fmic, apr r1 diverter valve, aem cai and its pretty deece

@bluestangGT2001 pagparts, integrated engineering, qedpower, eurodyne, mjmautohaus.

Pagparts has the best parts for power and by far the best customer service. Eurodyne has the best software (there are others that are good, but Eurodyne has the best features/options). MJM Autohaus has the best prices on replacement and maintenance parts and things such as upgraded suspension. And there are many other niche companies too. 42 Draft Designs, Eurojet Racing to name a couple.

@bluestangGT2001 Where were you looking? There is a ton of stuff available for the 1.8t platform. The stock internals can't handle a lot because the rods like to bend under torque loads above 275lb ft at the crank. Some people have gotten away with 300 or so torque at the crank, but it's Russian Roulette at that point. Not a matter of if, but when the engine tosses a rod out of the block. 250hp at the wheels is incredibly easy to do, no engine work necessary.
