Hey guys, i have a GT35r Fc.

List of mods/ addons

Street port full rebuild
re-amemiya exhaust manifold
gt35r turbo with synapse wastegate 50mm
custom downpipe with wastegate re-routed
550/1200cc injectors
Apexi power fc standalone
aem meth/alk injection
koyo radiator
old school trust fmic
sard fpr
supra pump


a few questions...

What would you expect this Setup to make on 10/15psi?

Engine holds 8"Vac on a 900rpm idle with 107psi on all 6faces


would this setup/injectors be able to handle e85?

Im not new to rotaries but a semi-newb to turbo rotaries...all advice/input is appreciated.

I'm telling you with 100% certainty that even if you changed for 550cc+1600cc secondaries you will max the injectors before you max out a gt35r* using E85 fuel.


*Assuming your support systems are good.

I think its a waste of time not using 17-22psi on a gt35r.

If you want to make the most of your setup you need 4x 1600cc injectors for E85 or 4x1000cc for pump petrol.

Your current injectors will work for lower boost levels and lower power levels. 10-14psi should be ok with 550+1200cc. For power figures, it totally depends on your standard of dyno. Realistically something like 350-390rwhp.

At 10 pounds your torque will be pretty low. It's not like the stock FC turbo where 10 pounds feels kind of punchy

how so?

Ok I wrote that a couple months ago but looking back on it, that's more of a subjective opinion on the driving experience than a technical/scientific claim.

Stock turbo on an FC will hit peak torque earlier and fall off. They kick you in the *** and then they're done. They're more efficient at lower pressure ratios and have a smaller hotside for good transient response. GT35 isn't really laggy as far as "big turbo upgrades" go but the feel is different. Bigger turbos like that don't "wake up" until higher boost levels if you are actually looking at the compressor map. You don't get the torque building as quick as a stock snail. It's just a different experience. Porting affects it too.

interestig, i was hoping to get a turbo upgrade that would keep the responsiveness of the stock turbo while getting rid of the choke off at 5500rpm.

I was looking at a larger streeport and an a gt34r. Should i just stick with a smaller t4 devided hotside such as .86 instead of 1.00?
