Again someone needs advice on what turbo to choose.
I'm gonna go single soon but don't know what turbo to choose. As a start im not aiming for any numbers, just to get it running good, but so that u know what kind of turbo i may need i want to get into 300 whp without much boost, about 12 PSI.
I've got an "OBX racing" manifold lying around that i thought i could get to use, but if i need to i can weld on a different flange. My engine is stock and im planning to get a custom FMIC for this and larger secondary injectors(1300 or 1600cc) What i want is a turbo that spools up fast( who does'nt) and can make the hp that i want, also be able to get alittle higher if i decide to rebuild and streetport the engine. I don't know much about turbos so if u know a great site that explain's everything from different house sizings and etc let me know. So what turbo do u recommend? Should add that i can get a new Garret GT40 pretty cheap with an A/R 0.84(0.85), but i think it's probably on the too big side. |
turbonetics 60-1 great turbo, fast spool , and will make 300hp very very easy , with boost its good up to 500~550 range (i could be slightly off)
for 300hp i think 1600cc inj are overkill 96 a/r on turbine side and off you go |
i agree, a 60-1 sounds like what you want
|
if you want to spend some more money, the GT35R kit should do the job nicely.

Stock turbos will easily get you 300 RWHP at 12 psi. However, if you want a single for different reasons, I can understand that. Just be aware that you don't need to go single for your power goals, and no single will spool as well as the sequential twins.

I have indeed read about a few people that makes 300 rwhp on 12 PSI but is that really possible on stock ports? And if so i think lots of the results is in the tuning and i'm not sure how good tuners we have in my country concerning rotaries.
This ain't the only reason though, i have a few reasons besides that to go single. Any comments on the gt40? |
how about this one?
garrett super 60-1, a/r 70. 4 inch inlet rear p trim 70 twin entry a/r Got this info from another forum. Someone is selling it for $1040 with a polished housing. |
Stock turbos
I concur with Max. I got something like 307 rwhp at 12-13 psi on stock turbos with an intake, IC, and open exhaust. I now have a mild street port and have gotten almost 320 rwhp at 12-13 psi by leaning things out slightly. Without the high-rpm ignition breakup, it may have been closer to 330 rwhp. I run it at 300 rwhp at the track at 12 psi with a pig rich a/f ratio all day long .

u can make 300 RWHP on intake, IC, DP, MP, and CB.

ok, i know it's fairly easy to get 300whp on stock turbos and engine. But i want single for other reasons aswell.
Do u think the turbo i suggest a few reply's back is good? |
i dont know specifics about that turbo, but that rear exhaust housing sounds too small for a rotary.
|
try looking at the apexi rx6 and HKS/XS t04e kits
|
what about the Blitz KKK-27 kit? is that a good turbo for our car's?

Originally posted by XSTransAm i dont know specifics about that turbo, but that rear exhaust housing sounds too small for a rotary. It is IMO and I'm sure in many other people's opinions. You can buy an exhaust housing and change it to .96 .84 1.15 etc as long as you buy one for a p trim exhaust wheel or whatever trim wheel your turbo has. But IMO for $1000.00 and then have to change the exhaust housing, you might as well buy a new one. |
The garret GT40 i mentioned has the A/R 0.96 exhaust and 0.84 compressor. Will this turbo do good? Will it be laggy? I don't know much about turbos( as u probably already figured) but im gonna read up on them, in the mean time i'm asking here what u think, cause here's where the reallife experience exists.
