S15 turbo choice

[jim_s15]

hi there i am looking to buy an upgraded turbo for my S15 the spec it will be is:
Walbro Fuel pump, 740cc injectors, Z32 and all controlled by a Apexi FC.

the bit im usure of is what turbo to go for as i would like to top mount it, but i still cant run really high boost because of un-forged engine and standard head gasket. so whats the smallest turbo i could top mount??

you wanna run external wastegate or what? can get a big gt2871r for you with ext w'gate or mod a actuator turbo.. really you could topmount a t28 or t28r with actuator still running..

i want to run internal for now untill i decide to go silly power. how do u mod the 2871r to fit a topmount mani?? and will it fir the japspeed top mount mani??

[bobbitt]

should nt be any issues really.. you ll need to rotate the core, a custom downpipe and longer feed lines.. gettin in fitted should be less hassle than removal to.. !

2871r will do what you need it to.....just have a look into the exhaust housing sizes and trims to find the one you fancy. .64 52 or 56 trim are good for response - 52 trim is standard nissan flange inet and 56 trim is a hose fitment

[jim_s15]

Will the 2871r fit the japspeed top mount manifold??

[bobbitt]

no reason why it should nt .. correct flange

the gt3071 will require a lot of work..

the gt2871r 52trim with ,64 ex housing is a nice bolt on for your car.. and should see you just under 400hp..
