Now several events have transpired. Cant remember if i shared this but 12~ months ago my wife and I picked up a green gen 2 RX wagon on a whim on a Sunday night during a thunderstorm

2 reasons. Its green and still has 99% of its clearcoat. Ive got a manual loom on my shelf and a spare 6 speed


Long story short i have a 98 loom, car its a 97. Subaru changed pretty much everything in 98 so have had to source a climate control setup and 98 spec airbag and abs pump and lines. Its currently completely stripped awaiting an engine bay paint job


The original plan was to acquire another 207 with AVCS for my BH and the non avcs 207 would go into the gen 2. While lying on the floor i realised having 2 EJ20 powered cars is kinda boring, and that ive been wanting to fabricate something again, like an exhaust manifold. Several weeks of research later and a mate parting a car we have this


EZ30R from a gen 4 with pre blown head gaskets. Perfect. Given they go somewhat straight into a gen 3 in an OEM like way seemed like a good idea. 

With that sorted i had to scratch the fab itch so sourced some flanges and steam pipe (which ive been wanting to play with also) and starting making a turbo manifold. Normally the done thing is to buy a set of raptor headers and stick it out the back and snake it up the back of the engine. I like making my life harder and doing it like Perrin did in 2006 with their STi so routing it like a normal turbo subaru. Most of the reason people go up the back is cos its a factory EZ car and they dont want to change the subframe, even less so if theyre paying a shop to do the turbo kit. To make life even harder i want to do a twinscroll setup as well

Have tacked up the passenger side bank and am pretty stoked with the result




Ill be welding an extension to the thermostat housing so move the hose further away from the manifold. The heater hose will come around the back. Should be fine in some fire sleave

Crossover pipe is also tacked up, this may change once i make the second bank as it has to do a 180 


90% chance ill be running an external oil cooler so space is left at the front to run lines out.

This wont be going into the car for a while. To do it "right" will need some pretty serious money and i dont want to be without a car at least until i can pull it apart and do it all. Ill be using a wire in ECU like a Link Fury X. Obviously with the head gaskets pre blown theyll need doing which will get head studs and some thicker cometic gaskets to drop the compression a touch.

Turbo wise looking at a G35-900 with a twinscroll 1.01 T4 housing. Did think about a G40-900 for giggles but i dont think it would even fit between the intake and brake master. For reference Perrin used a GT4094 back in the day and it spooled up like a GT30 on an EJ25, which is quick

The red GF8 WRX belongs to a mate that is gathering dust at my place for a while

Short version of a long story
Rear brembos and backing plates are on


Engine came out to fix either a dodgy cam seal or not enough slaz on the front cam caps. Turned out to be installer error and cooked the cam seal putting it in


Converted to a GD style centre entry rad for more OEM ness


Went camping in the alps with the boys



 

Images are massive but youll live

Had a big post written up and the forum chucked a wobbly and deleted it.

Will try again later

If we're talking about the jerking around when say cruising in a carpark in 1st gear around 20kmh. My understanding is its the ecu turning the injectors off/pulsing for emissions/economy things

Goes away/is miles better with an aftermarket ecu. Tune may also fix it

Not a viable solution for an NA shitter

Doubt swapping the IACV would work. The gen 3s are usually 6 wire stepper motor setup. Everything else is 3 wire PWM type operation

Rapid fire summary of whats happened

Wanted a new turbo that would spool a bit faster. Found out Mamba who did my GT30 housing also did G25 housings so chances of direct bolt on were high. It bolted straight on



Makes about 20 psi by 4k, much easier to drive. Little bit less interesting but arguably "better"

Swapped to a gen 4 remote res power steering setup in order to route the intercooler piping down between the chassis rail and the radiator





Made a new 3" CAI and had it all powder coated textured black


STi box arrived


Managed to solo swap it without dying


Cruising RPM is perfect for non avcs 2L


New shifter linkage and NOS v7 STi knob


Changed the muffler from the HKS silent power to an Apexi World Series which could have the tip extended to clear the oem aero lip to fix the soot being spewed all over the car



Also installed a cat back in the car


Took it on a trip into the Alps for a family holiday


Installed some hard race camber arms as running nearly 3 degrees of negative camber isnt it and had maxed out the whiteline bushes


Is now back to around -1.5 all around

Got married in tasmania. Took the car over on the ferry as the "wedding car" and did a bit of a trip around aferwards





2800km total. Thats up to as of 2 weeks ago. Car is still dirty
