New engine/trans setup has about 45,000 miles...

The car dynoed 375 rwhp with the current tune/setup @ 14 PSI. Runs low 12's in the 1/4 mile no problem.

What else do you guys think/suggest i would need to upgrade other than changing my existing tune to make a GT35R Turbo setup work? I was looking at the A-Spec Tuning GT35R Turbo Kit...

Any input is greatly appreciated, thank you!

 

is that fuel pump good enough for the power ur looking from the new turbo kit?

 

Dual fuel pumps would be a better option.

Increase your boost to 20psi with A/I.

You should also be running in the low's 11's with that setup and 375whp.

 

you don't need dual fuel pumps with a GT35. I used to run 21psi on my T04S (slightly smaller than a GT35) with no problems using a single rewired Supra pump. There are plenty of guys on this forum making 500+ on single pumps. Use dual pumps when you need it and only when you need it. Otherwise it's just more cost and complexity.

I'm guessing your "NipponDenso Upgraded pump" is a Supra or Cosmo pump.

 

Single pump with A/I here

 

If i launch real hard, yeah it should be in the 11's, but i baby it off the line lol...

Car runs real hard the way it sits right now, just looking for a bit more fun!

Yes, it's the Supra TT fuel pump.

 

Not seeing wastegate or wastegate(s) on you list. Also, spend the money and fab up some aluminum hardlines to your WG. The overkill will give you peace of mine. Just my .02.

 

im still on the stock twins so im running the stock WG...

 

i see the list fine. Supra reiwred pump should be ok for 500whp. Other than that go for it. I managed 429whp@15psi wuth a pt67 turbo aka t04r

 

so my primary injectors at 550cc and secondaries at 1600cc are just fine?

 

what are your power goals? 550/1600 should be ok for 500whp maybe a bit more at high duty cycles.

 

Maybe I'm missing something here, but your post asked "what else will I need" and I didn't see aftermarket WG listed. If you're going single turbo you will need an aftermarket WG unless one is provided with the "kit" that you're purchasing

 

I went with a fuel cell, just for safety's sake.

 

check out turblown.net Elliot can put you together whatever setup you want. I asked him about a 12a mani and he was like sure done. Custom 12a mani, GT35r stage v divided inlet. planning on about 400 rwhp at 15 psi. 12a carby. make sure your exhaust is big enough. egt sensors at all?

 

Yep, the turbo kit im looking at comes with everything, including the WG

 

I understand the importance of EGT's, but i currently do not have any EGT gauges/sensors installed...

mmm, should i get them installed? i thought i could get by looking at my Wideband gauge...
