Looking to put a bigger turbo on my car then the 40r. What turbos should fit the manifold that came with the kit, just any t4 flanged turbo??

 

Yep any other t4 flanged turbo. You really don't need to put a bigger turbo, if you want to make more power, but a bigger AR on the turbo. Step it up to a 1.32 or something like that.

 

Id rather have a larger inducer ...64mm aint gonna cut it for what I want. Plus I havent seen any truly impressive #s from any 40rs yet....Im aiming for over 500whp..

 

Swap the guy on the for sale section for his gt42r!!

 

hrmmm
!!

 

or check out the for sale section... if your looking for a brand new kit with ceramic coated manifold and downpipe for less than you pay new... https://www.rx7club.com/showthread.php?t=373053

 

I have a gt40r on my car right now LOL...thanks though..I am looking to keep the rest of the kit just change out the turbo for something larger. The kit itself is incredible but the turbo is too small for what I want.

 

gt40r small???

sp63?

 

gt40R is still bigger than a sp63...

 

oo...

make sure the new turbo also has the same exhaust outlet style as the gt40r or you'll have to change the flange on the down pipe...not that thats so hard but it would be a bigger pita then just swapping a new turbo in. Whats is the outlet anyway? 3 inch v-band?

 

the outlet is 3 inch v-band...

 

If you go really large the turbo might not have enough clearance. In any case,
do you have a dyno plot with different psis? What port do you have? Are you just looking for track performance? What psi are you looking to run?
