Just get the T3 unless you already have a T25 setup

MK4 UPGRADING...

WG is the T25 version. Comes w/ a cutdown version of the 30R wheel. If you are really bent on spool, then a .64ar housing should be fine and still make some decent power. I have done a setup that on 30psi and race gas made around 400whp on the T25 internal gate. That was not at that elevation however. Shouldnt really rob a ton as far as overall power, but the spool will suffer a little up there...

Got it so a GT3071R-WG with .64ar will make at least 400whp what do you think?

Also, with this WG version is a big diffrence with the gt2871R ... in top power i mean...

MK4 UPGRADING...

It has made 400whp on a pretty much bone stock small port engine w/ 30psi and race gas (only rods were added). As for the differences b/w that and the 2871r, power-wise... not much. But the spool will be better on the 2871R for sure which makes the power delivery peakier.

Im saking this because im forging my engine, rods and Pistons, but i dont really know which turbo is the right for me, i want to make big power because else what is the meaning of forging engine, but i want to go for PUMP GAS, so im still doing my homework to get the best turbo kit., with your experience what do you recommend.

for sure i want to get at least 400whp in pump gas, which AEB HEAD and which BIG PORT HEAD MANIFOLD, any sugestinons?

stock ported head would work?

1) Cheapo route - Keep your 1.8, use the 2871R, bolt on other stuff as you see needed. You should certainly be able to make 340whp with the basic setup and good tune and parts like a SEM/bigport cyl head with give more power with even better spool (call it 380whp, obviously there are a lot of factors)

2) Spend more get more route - Since you're building the engine anyway, spend a little extra money and go 2.0, get the 3071R, and easily get 400whp while having more ultimate potential than the 2871. Spool will be the same/maybe better with the bigger engine + turbo while also giving you more torque to further help in coping with the thin air

OR you could get a T3 2871R, build your engine, and easily swap to a bigger turbo, but now I'm being a pain

Got it i fout a AEB here in vortex.

Turbos are actually very good for higher altitudes, the amount of air the engine sees doesn't really depend on the barometer but instead on the WG spring I'd say your two best routes are rods+2871R or stroker+3071R; the price difference will be ~$1400, so it depends on ultimate goals and funds: 1) Cheapo route - Keep your 1.8, use the 2871R, bolt on other stuff as you see needed.

Very nice information (fromo you all) i want to stay in 1.8 because of the money and because i want to get my 1.8 to the limit jeje so in 1.8 with rods and pistons what will be the final option (setup) to get top power on pump gas? let see your gessseeess...

MK4 UPGRADING...

I know im happy with 400whp so will se how it goes!

MK4 UPGRADING...

If you're trying to do it on the stock smallport with just drop in rods and pump gas...you're going to need a 30r or a s256, pte6057, or something along those lines.

I run one of these kits and trust me no where near 400WHP.

Arnold from Pagparts is going to set me up with a T3 Flanged exhaust housing for my 3071-WG. (will post dyno numbers at some point with the E2 kit and the T3 flanged so everyone can see the difference)
