Far out guys thanks for all the feedback!
I'm actually a little confused now with the whole stroker kit thing haha, here is a link to the place that I am looking to buy the engine off, and from the way they talk about it it seems they make it pretty bulletproof. Would it be Harder to get good results out of a stroked turbo compared to a normal turbo'd engine?

And to scuba-roo , I am hoping to do most of the mechanical side of the swap myself, although the wiring loom, and anything I might need to change or cut on the interior to allow for the manual gearstick I might take to a workshop as I don't like stuffing around with he electrical side of things and I want the interior to stay looking schmick haha

Hi,

I'm slightly lost (nothing new) - are you saying you want to stroke out the N/A, and then later on down the track convert it to a turbo engine?

Cheers,
Nik

From experience, ben at ichiban usually gets a nice halfcut. got my gen 3 converted and after ironing out a few kinks it runs like a dream.

im looking to buy a 2.6 cosworth engine (its what they call it on that alldrivesubaroo website) which is just the ej25 stroked out obviously and they replace all the internals with much stronger components apparently.
just dont know if its worth it, wondering the potential for extra power compared to the problems i might get while trying to turbo it.

sorry if im sounding a bit all over the place haha

I reckon you'll probably regret it if you start with just that motor. Best bet, like others have already mentioned, is to start with a halfcut and a conversion. This way you will have everything else that is needed for your intended goal, ie. gearbox, diff, brakes, loom, turbo ecu, etc. Then when ready for more power upgrade again to that motor.

Best to read through those other mentioned build threads to gauge an idea for everything else that is required to convert your car.

Uneducated assumption, but that looks like a turbo motor to begin with.

What exactly are you trying to achieve?
Power?
Bragging Rights?
Or just a fast car to put a smile on your face?

If you are looking at that engine, id say you have a large budget?

From what i can tell its a ej257 block, they get the extra little bit of stroke by using the 81mm crank as opposed to the 79mm one.

But dont take my word for gospel.

Personally i think you should find a decent version 7/8 half cut and get that going the ej207, brembo's r180 and 6speed box will keep you gen3 happy days for a while.

Then you've got the option of using your stock ej25 block and sleeving it and forged internals, and mating that to the STI heads.

Or upgrading the turbo intercooler injectors etc with the 2L. Which should handle 250kw@w for a long time.

I think its been mentioned before but A&M auto's do the wiring. Or whole conversion if you want. You'd just send your wiring loom and the loom from the halfcut to them, and they'll send you one back ready to plug and play.

Best of luck

[Pat-01obk]

Haha Adam I'm kinda aiming for all three of those haha
But by the sounds of things I am more leaning towards the halfcut option, i guess it will make it far easier in the long run and save me buying all that extra stuff I will need to make it reliable.
Can anyone recommend a good reliable site for finding decent halfcuts?
Thanks heaps for all your help guys

Yes, agree with everyone here. Get the v7/8 from japan as either a cut or an engine package. For an outback I would go for a cut, as you will then get the turbo rated box, shafts, lower arms etc. (Which will be needed at some stage if you are chasing big power)
Cosworth motor should be able to handle anything you throw at it, but at about 10 - 12k for just the motor, its going to be an damn expensive conversion!

Big approval from me re AM Auto. Those boys did my conversion, no problems, and the tuner/mechanic said they did a great job, best he has seen in a long time regarding the loom work.

Remember you can always throw a new worked 2.5/2.6L motor into it once you have all the turbo and underlying stuff sorted and running well. Matter of bolt new motor in and re-tune.

After all the preparation and planning to do a motor conversion with my mates, I later decided to bite the bullet and let a well known mechanic do the work for me!
Alan and Miles up at AMAuto at Noosaville, QLD did the work and I've never been so impressed in my life!!

Full engine/driveline/gbox/dash everything was changed all in under a week. I drove in Monday and drove out Friday arvo.
This was only last week and the total for the conversion only came to $2500.

my advice and as many others would agree, PAY SOMEONE ELSE TO DO IT AND SIT ON YOUR ASS AND ENJOY THE STRESS LESS JOB.
for $2500 you can't really go wrong.
