As said above
Sr @350 no problem
Just get turbo, ecu, injectors, few small bits
Where a rb25 and box gonna cost alot more
Ran sr20 at more then 400 with no problems

Il be running it higher now soon too

SR internals are good for 350 easy.some have got reliable 400 out of them. Turbo ,injectors,intercooler,ecu,fuel pump and z32 afm should see ya there. If its only 350 your looking for get a msaller trim turbo for less lag like a 2871r 0.64.

I'd go with the 25 there a serious engine and will get more power out of them plus 6cylinder big winner
