Well Ant lots of options .
Ill look forward to see which road you go down . just one more trinket …… do it once and do it right !
Keep asking questions even if you feel stupid for asking, no one knows it all !

anthonymcgrath

Yep agreed. I think the first thing is to get the engine out and have it assessed.
Turbo came back today with clean bill of health and wasn't leaking or using oil.
So I reckon it'll be pull engine and if rods an pistons ok then it's gonna be a build and refresh really.

I'll get a wideband and boost gauge installed too. Need to find out where is best to fit wideband sender actually.

The impreza has a wideband(ish) lambda sensor already, so unless you specifically want to look at the gauge, you can get an obdii interface and use e.g Torques on Android to get an idea of mixtures. The sensor is only accurate down to about afr 11 (when comparing my real Bosch sensor Vs the obdii data), but gives an idea.

anthonymcgrath

Ah ok it has wideband already that's crazy lol. I have one with a gauge yeah so wouldn't mind monitoring it. I actually tried to get torque on android to connect but it wouldn't have it.. might be my obd2 plug dongle that was borked maybe.
Where can I mount the wideband sensor I have? Weld a port in the downpipe or somewhere else?

It replaces the existing lambda .

With the power you are going for there real is not any point going fully forged as i said in a previous post why not get a brand new EJ207 short block what comes assembled with forged pistons from factory and is good for 400 bhp and put your heads on will work out cheaper and you still get a brand new engine

anthonymcgrath

So is the ej207 basocally the sti version of my ej205? That sounds pretty much exactly what I need esp if it's new.. but where do I get one?

Edit.. AS performance is one option as mentioned but anywhere else? I think I may have seen new short blocks sold on even places like eBay? I take it those are from Japan or something.

Import Car Parts ICP brand new ready to go and built by robots .

I have a welded on bung on my downpipe.

I found the Bluetooth adaptors are a bit funny on the Subaru. My first one connected fine to my ford, but wouldn't connect to the Subaru.

Russell38

Importcarparts stock them as performance may be cheaper EJ207 was the engine the jdm sti come with much stronger than the EJ205

anthonymcgrath

Wow ICP sell them? That's ace. Ok I'll have a check and see what's what. As someone said I've got a good few options here it seems! Thanks chaps.

Yeah I'd like to get a boss welded on my dpipe (aftermarket one I believe) and I can get the sender fitted then wire it into cabin. Cheers

Import car parts ej207
So 2200 inc vat ...that's not bad at all if I'm honest. Altho I need head gaskets (no clue which) and arp studs.
Also says non AVCS cars need to modify breather system.. no clue on that stuff either for these cars.

To give u guys an idea my quote for forged ej205 was 2100+vat.. for that I get forged pistons.. rods.. new bearings new studs all bores cleaned up and polished and heads done too.. basically a fully restored tall engine block ready to drop in.

stockcar

if you contact the 'right' people they will not only assist on pricing but have the knowledge to give you the exact parts required for the most reliable set-up........

Thanks for all your help guys. I decided to run with this option and purchased last week. It said in stock so hopefully it'll arrive quickly.

Yesterday we got the engine pulled out.. bloodbath but 3 hours later myself and a few friends had it removed. I'll be taking the heads off this week and taking them to get built with the new ej207 and some ARP studs. I'm also going to find out what happened with the 205 short block too.. friend says piston4 will have give out.

Question...is it worth me going with a slightly thicker head gasket to get the best from the vf35 turbo?

I'm also considering a new replaced front subframe as the other looks very tired and has been welded to pass an MOT anyhow. They aren't expensive.
Also gonna get my BC coilovers on too and looking at the front disks they look super shot with a big botox lip so going to get a K sport kit on the front.

Won't be a big power car but as some one said if it's doing 280 to 300 and handles and stops great I'll be happy!

Russell38

Speak to ASPerformance he will give you advice on what head gasket to use and will be cheaper than importcarparts he is very knowledgeable when it comes to subaru and will have everything you need call him on 0191 410 3770

anthonymcgrath

Will phone tomo ta

One thing I'm trying to do is keep the cost down so I just can't be shuttling the car to tuning shops sadly. I have to get as much done as I can myself and tbh half tempted to do the head gasket and head fitting myself.. done it on skylines plenty so can't be much different for scoob lol. Some ARP studs will definitely help too.

Russell38

I would get the map checked once built and will need to be run in also check sump and oil pickup for metal flakes

anthonymcgrath

Definitely will be running it in and getting the tune checked... hopefully wont cause too many problems.

I want to plug a wideband I have sat in my boot into it too so I can monitor that.. I think if I weld a boss into my downpipe just down the vertical part of the pipe (about 18 in from turbo) I should be ok. I know there is one in there anyway but wouldn't mind getting my own in there.

Also if I can source the ecutek software I should be able to connect to the ecu. Altho I want to get a link G4 too as I'm more clued up on that software from skyline twiddling.

anthonymcgrath

Hey guys thought I'd update this thread too..

We pulled the bits off the block in the week.. manifold off.. cylinder heads off etc..

We found 1cm of coolant in piston 2.. most plugs were wet and honked of fuel. Head gasket looks like it was leaking. The block I'm told was decked altho checking it myself it certainly didn't look it with significant warp.. same for cylinder heads so no wonder if chuffed steam and blew it out the back.

Checking modene no shavings of metal and none in the filter. Dropping oil it was clean altho smelled fuelly.

Anyway got a shiny new short block ej207 and I'm getting my cyl heads to the work shop this wkend. Once there they'll get cleaned up and sorted out and fitted to short block with new head gaskets and new timing kit.

Btw can anyone tell me the head gasket thickness? It looks like 1mm but just wondered. Is it worth me fitting a thicker one with the vf35 turbo?

Also what size oil pump do they have? (02 wrx wagon)

Cheers chaps

Ant, I did ask before if the oil smelled of fuel so it could possibly be getting too much and might be bore washing, I would get it checked for peace of mind. you do not want it happening to your next engine.

anthonymcgrath

Cheers yep I will definitely get it checked. Yeah it smelled rich on boost previously and was thirsty. I thought Andrew Carr was meant to be good at tuning because apparently that's who mapped it. Either way I've kinda lost confidence in the map that exists :/
