Hey Guys,

Following on from my intro thread http://www.perth-wrx.com/vb/introduc...ing-perth.html) it's now time to start my big power build.

I've decided to go the Closed Deck 2.2L Stroker route. It looks like I've managed to source a block (subject to being able to organise shipping it from Victoria). However as I'm new to Australia and Perth I don't know who to use for preparing the engine block.

As it's a 2.0L Closed Deck Block it needs to have a bit of work doing to it before I can even contemplate building it. It will need the usual bore and plateau hone as well as a block to head surface skim but the major thing is the conversion from centre thrust to rear thrust crank. It will also need a 14mm head stud conversion too.

Can anyone recommend somewhere that will be able to do this and to a high standard as I'm aiming for around 450KW / 600bhp.

Cheers

Daz

Here's a couple of my previous builds back in the UK. But there I knew where to go for the machining work, here I don't hence the question. Any way first up a 2.1 stroker.
Cosworth Rods, Roger Clark Motorsport /Omega Stroker pistons.

Neil Herbit at the engine exchange is a machinest & engine builder. He runs a hi powered Wrx. There is many members on her have has motors built or machine work done by him. He specialises in this type of machine work and is set up to re oil phase Subaru cranks.

Awesome thanks.

Here's the 2.5 I did with the front mounted GT35R turbo.

































































































This is how the car looked when finished.

You carry out your own tuning don't you ? I think I have met you last year

I've just moved here from the UK so unless it was there I doubt it

I dont have anything to add about where to go to build a high HP ej. But i will be looking at building something eventually and am curious as to what those round dowl looking things are? And why you would go with that instead of a full closed deck setup that i have seen from deshelle and other on their high hp builds?

Does it provide similar strength without restriciting coolant as much?

You've answered your own question pretty much.
The closed deck inserts weren't available in the UK when I built this. It's only recently they've started to do them. The inserts provide the strength where it's needed without restricting coolant flow.

They were used by few well known tuners in the UK to good effect in their 800+Bhp race cars. The dowels were easier to do, cheaper and did the same job. The block I built is 6 years old now and is still going strong at just under 600bhp. I would probably do another but I really want to do the 2.1. As didnt get to finish the one in the first set of pics due to moving here.
