Here is my 1jz vvti swapped into my s13.
Parts list:
Jzx100 engine and 5 speed R154 (this trans is factory extended unlike older r154)
Spec stage 3 pull type clutch
Arp flywheel bolts
DSS Aluminum 1 piece drive shaft
Griffin Alum radiator
Garrett 18x11x3 Ic core, made my own tanks
Alum charge piping

Drift motion steel turbine exhaust wheel upgrade/360 degree bearing upgrade
Custom stainless downpipe that bolted on 22ft/lbs and 26 hp on stock boost.
3 inch stainless exhaust
As pictured made 295ft lbs and 313hp on stock ecu and wastegate, no tuning or boost controller.
This is the pipe I made. I did back to back dyno test stock vs mine, only changing the pipe and it made 22ft lbs and 26hp. I made a 3 inch pipe from stock 3 bolt outlet to where my v band connected on exhaust for the stock one. This way it would be fair comparison. I was actually worried at first when the stock one put down 273ft lbs and 287hp. Then I put on mine and it made more power everywhere in the power band and extended peak torque 250 rpm. I believe this pipe is better than the tomei unit, as that one makes 30hp gain, but they are running 23.5psi boost, where mine made 26hp gain on stock ecu/boost. Im sure mine would shine even more with elevated boost and ecu tuning.
