Great. Let me ask you this you know the 2jz story.. 1000hp on stock internals (when done right i guess)... whats the Subie STI engine story?

[SF5]

the sti shortblock well the 2.5 litre because u should know is americans who love to push limits. i've heard 640 or so.. but you do understand this engine doesn't rely on harmoic balancers and balance shafts, its also a semi closed deck block all aluminum, the engine is horizontally opposed so there is a tendancy to create lean spots in the combustion chamber if injectors aren't placed properly, remember the fuel mixture isn't falling ontop of the piston rather along side it.. wierd stuff lol. The wierdest part is that the engine is like a sandwich, guts in the middle with two sides, the transmission as well. few other limitations to prodicing power would be the distance the turbo is away from the exhaust ports, and tight space for a big turbo. I just want 100more hp from mine, thats it!

encountered an obstacle in the wiring, seeing that subarus have one harness which basically goes round the car, the swap ppl cut the harness, so now i'm making the section that mustive stayed in the car, its a painstaking process

A Picture is worth a 1000 words

I was half asleep when i posted those 3 pics, I documented the whole thing to benefit those who wanna try it. I am still undecided to post the wiring. I have drawn up my own schematic and will have a hybrid harness, basically my harness from my ej25 with two jumper harnesses one at the ecu plug and the other downstream so, basically a plug and play affair no need to the sti wiring. Also retaining full car functions ie a.c, power steering, cruise control (actuator will be relocated). Of all the swaps I've done I will have to say this one is the most involved, not hard just many many steps. The cross member is a bitch, especially doing it all by myself with no one to help me lift the damn thing, more pics coming up





Thats where I stopped, factory tranny still in


Also when changing cross members from non turbo to turbo cross member, you're going to need to either change ur sway bars or sway bar bushing brackets, I'm gonna do one or the other depends on the budget.

STi Speedometer cable on STi trans

Forester Vehicle Speed sensor (VSS) Unfortunately its made of plastic and dry rotted need to order a new one cause it mashup while trying to losen it.

STi Motor sitting in its resting place, bolted right on in about a 30mins, separated the tranny from the engine to inspect the clutch, there is an aftermarket one in there red clutch cover, and a momo oil filter.

couldn't take pics of it going in cause i had a few spectators one helped operate the hoist while i was guiding the engine and trans in place.



Things to do
Fabricate 3" downpipe
Install Walbro Fuel Pump
Install VSS
Install Differential
Plug ECU
Install Radiator
Modify A/c lines (JDM connectors are bigger high and low ports are reversed)
Service transmission & engine,
Service differential
Torque everything down
Bleed clutch
Test Drive!

Wash car drink a cold bottle of water take it all in.... radiator won't be here till next week

nice work man - thought u wudda dress the engine a lil first ( ex the Manifold red )

once it starts and runs well, the intake is getting powder coated, timing belt is being changed, downpipe is getting heat coated as well.
