Hi All,

Here are a few pics of my car after my eagerly anticipated engine build.

Pretty much everything is new, apart from the cylinder head casts.

I'd like to say a huge thank you to David and the guys at API, a true gent and ultra patient with me. I really cant recommend them enough.

Its running in at the moment, 900 more miles to go!!!

In total everything cost £12k, there wasn't much to use from the old engine, so almost everything is new.

I'm looking to get around 450/480bhp from it.

12k great spec engine and it looks like that on the exterior

Illest

if youve spent all that money on the engine, you might as well go rotated gt30-35.
also a 6 speed should be on your shopping list for that power. for a 12k build i would be expecting 550bhp +

12k on the engine build?

al02uk

iTrader: (1)

It has a 6 speed box. Apologies, I thought I'd wrote that. I've added it to the list

Everything adds up quickly (turbo and clutch was £3,000), like I said, the cylinder heads (although had a lot of work done to them) are the only original part of the old WRX engine, everything else is new. Then of course there is the labour, mapping/fuel etc. £12k is about right

If you are after 550+, you need to look at pinning the block, or going down the CDB route. I'm more bothered about it being reliable. 450-480 is fine for the road.

It's actually an APi developed Blauch billet using twin scroll technology. It was designed for my JDM 2.0 Hatch, but that is taking so long to get sorted out, that we have used it on the this build. First results are confirming what a good turbo it will be when fully mapped. We were having trouble holding it back when setting the run in map, the spool is phenomenal.

At the mo the car has .9 bar boost and a 4000 rpm rev limit, but it'll see most things off even like that.

We are very pleased with the way it runs.

Should have just let you write the spec list really, I was guessing most of it.

nice build mate,what brakes and suspension are you running?SJ.

al02uk

iTrader: (1)

Thanks guys, much appreciated.

SJ - The dodgy bit, brakes and suspension are still standard.......

APIDavid

iTrader: (4)

Sure thing, they come with a £12,000 rental tag. Just



let me have a debit card number and it'll on its way to you today..............

Tidgy

david, are the heads avcs?

stonejedi

iTrader: (51)

to start,i have to say again your build is first classyou will be ok running the engine in but when its mapped for full power the standard set up of the brakes and suspension will start to show there weakness,try to make them your next priority you would not want to stuff all that hard work and money through a brick wall.SJ.

No mate, they are the 2001 WRX heads.

Tidgy

ah k, be interesting to see what graph is like when its done, my 2.5 is on avcs heads.

al02uk

iTrader: (1)

Yeah I know mate, as David said earlier even now it goes like a rocket.

The turbo is great (and ultra loud), I'll have to look into the brakes first.

I'm relocating to America in the later part of the year, so I'm in 2 minds on if i should take it with me, which is difficult, but not impossible or sell it.

I've had the car for almost 8 years now, so it's a bit of a tough one.

stonejedi

iTrader: (51)

8 years!!!!its part of the family nowSJ.

APIDavid

iTrader: (4)

They started off as WRX heads, almost the only bit left is the original WRX casting

Tidgy

just out of interest why do it that way ratehr then just sourcing some later 2.5 heads?

APIDavid

iTrader: (4)

Most 2.5 heads don't flow well [ Kev will tell you that too ] and as we had the originals, it was just as easy to gas-flow them rather than buy heads and do the same. Saved the owner the cost of head castings.

David

Tidgy

didnt know that. so what does it tend to do, reduce sppol or lower peak?

APIDavid

iTrader: (4)

Part of APi's family too, it's been here best parts of 3 years.

We work even slower than Matt Clark

Seriously there was ' no hurry ' and we took that to mean ' No hurry ' .

AL02 has never once mentioned the time it has taken. Perfect customer in many ways.

I've moved house twice whilst it was there too!!

It has pride of place underneath the CCTV camera.

The poor Audi has been abandoned, I havent touched it since the Subaru came back!
