Thread: T28 vs t571z

Sorry, I guess I should have explained myself better. The AEM fuel pump I installed is E85 compatible (green one), I have in the past ran a mix (E30) but that was on the stock T25 @ 10psi. I agree with you on needing bigger injectors for the 18G, so for the time being I will stick to 93 octane.

My original set up (DE+avenir kit) had some issues with injector on cyl #4 staying stuck open, It eventually must have washed out the lubrication film on the cyl wall and eventually scratched the surface causing it to loose compression. This put off my 18G upgrade.

I had a spare VE short block and decided to freshen it up with new piston rings and have a simple set up. I plan to stick with the OE 2.0 VE cams and run 10psi on the 18G until I get bigger injectors. I was looking at the MPI fuel rail + ID 1200 injector kit since its a pretty reasonable price.

As for the manifold I went back last night in search of that post from Miko, and it seemed like this was mostly for the GTi-r manifolds as milling the T2 flange off by 3/8" would move the turbo up giving you some extra clearance.

According to Vadmin's build thread, the Avenier manifold makes it easier to install a 3" turbo intake, so I do not think I would need to mill anything. I might still have to grind the hex plug on the block to clear the compressor housing.

i ran this turbo for a couple years on my infiniti g20. The turbo hauls ass, hits way harder than a t28 and pulls all the way to the redline like a freight train. i ran a avenir manifold and i had to grind the block (very minor takes less than 5 mins). My turbo had no water lines so that made installation simplier on a DE-T. the turbo will handle over 20psi and can in many cases make up to 360whp, I made 280whp at on very low boost back then and no t28 b13 (much lighter than my car then) could outrun me.

Thanks for the feed back. I cannot wait to try this turbo out.

some compressor housing with a 3" inlet will require some grinding but it will be less than a GTIR manifold.

We gotta get you guys to Clarify which turbo you have. The 18g has the Huge 3" intake side and 8cm T2 frame exhaust side. The T518z has the same wheel as the 18g on both sides and an 8cm exhaust housing but the Intake housing is smaller. The T517z has a smaller intake wheel and smaller intake housing but still has the 8cm T2 framed exhaust.

the S2K t518z it comes with as 10cm turbine

I think those are T3 though

nope, the S14 kit was T3

That would be the exhaust housing to use on a VE then. Little more lag but more power up top. The 8cm housing with S4's has power falling off right around redline.

/\ what if one were to change the exhaust turbine to a 7 blade on a 8cm housing?
