I am currently in the market for a good turbo to throw on my current setup (sig). I am also in the meantime, building a 2.3 stroker using a spare shortblock. I am looking for a turbo that will add some good power to the current setup and then be still pretty efficient with the stroker. Not looking for HUGE hp here, just around 450+ with decent spool. I am currently tuned with 91, but meth or e85 is forseeable in the near future. Torn between the green and the bbk full. If anyone has any thoughts or personal experience, I should would like to hear it. Thanks.

 

I say go with the T67 turbo. Lag on a stroker is not bad AT ALL. If you don't want a lot of poer, keep the boost low. On 20 psi my car made over 500whp.

 

Try the FR kit w/ the GT4088R; I've seen a few posts with some killer graphs on that combo.

Alternatively, if you want a turbo that's rebuildable, you might select a BW S300SX 91-79 (which is supposed to flow a bit more air than the GT4088 yet spool the same). You'll save some money with the B/W over the Garrett.

People have also been having a lot of success with the GT35R on a 2.3L stroker (again the FR kit). The B/W that's comparable to the GT35R is a BW S300SX 83-75.

Geoff (@ FR) did a head to head test between the GT35R v. the BW S300SX 83-75 and the BW seemed to be the winner on a stock block. Transient response, spool, cost, durability, and rebuildability were all deciding factors.

I was kinda wanting to stick with my ported and coated stock exhaust mani...

 

Vendors?

 

or..u should by my 67ptrimHcover turbo i have for sale!..lol 618whp on 93/meth

 

fpred

I don't think there is a better answer

 

FP RED or like a GT30R 35R might be to much for what you want but def will make good power for 450 whp you really wont get a 35R into its efficiency rang I think... A FP RED and 30R should be good for that area.

 

do that hta 35r and be done with it and never look back

 

If sticking with the stock manifold your limited to the fp red.....no doubt about it

 

Run a twin scroll 35r with a billet compressor wheel.

 

I actually have the line on a good, barely used ATP gt30r turbo kit. However, whenever I have mentioned this kit in previous threads, a lot of you have said it is an outdated, inefficient kit. ?????? Help guys, I am having a kid in may, and I HAVE to get this done before then. God knows there will be no more $ when the baby gets here.

 

do it, then if it does not perform to your liking you can convert it to a true T3 setup later
