GT35R - T3 or T4, help me decide
This summer I'm going to get a turbo kit for my FD which has turbo back 3" exhaust and a street ported engine. This car is mostly a street car and I'm having trouble deciding on a turbo kit.
1. Rx7Store GT35R kit - T3 .82 Exhaust
2. A-spec GT35R T3 tubo kit
3. A-spec GT35R T4 turbo kit
I know a lot of folks have had good luck with the RX7Store kit but I was reading that it could chock in the high end, and I was thinking since im ported this might be a bigger issue for me? I'm looking for a setup that will spool quick and make good power... around 400rwhp+ is fine.

Sean, is the 3574 kit the same except for the turbo? I'm thinking it's THE choice for people who want a good single kit (with upgrade path!) on a budget.

Yes, and the water and oil fittings change as well.

There is no non BB GT35 with a 68mm wheel(if your wanting to run the 35R compressor), at that point you might as well consider a smaller turbo. Closest you can get would be a 3572. Which runs a 51/71mm compressor instead of the 61/82mm compressor. If you can source one, you can possibly find it with a 54/76 comp. but then you also need to hope you can get something sourced other than the 1.18 rear.

I'm not looking for more power (yet), i just want quick spool and good top end. Does your GT35R kit offer the good top end of a T4?

No you dont. althougth a T4 would be a better choice.
On a completely stock motor stock ports with a T3 gt35r 1.06 I made 403 RWHP at 15psi PUMP GAS last year. Then I ported the motor and made 428rwhp at same 15psi again on pump gas.

once ported spool did get pushed back about 500 rpms. I get full boost by about 4100rpm. You dont really notice the difference in spool but you sure feel the difference in power it made.

I once saw a 13B exhaust flange next to T3 and T4 flanges, and it made me wonder why anyone uses the T3 in the first place. The T3 inlet looks downright tiny compared to the area of the two 13B exhaust ports, and the divided T4 looks slightly small as well. Note that there weren't any stock turbos to compare to, so I might be completely off base here.
