Forged rods and pistons, large exhaust valves with ported heads, air pump delete, Perrin front mount, DW injectors, SC46 turbo etc. full drive drive out build, run in by us and mapped on Race Rom by Martyn. Finished to usual Enginetuner standard.





Power? - Adequate..

 

jesus its tight in there, you must have hands like a lady lol

 

Looks tidy Alan, although it's adequate have to ask what it made lol?

Also what clutch is it on or can the standard clutch take a beating?

 

Very nice, factory looking finish. The more I see them the more I'm wanting a hatch now

 

My hands are just about worn out, which is why I employ those with bionic fingers.

 

Go on, make a guess.. SC46.
We used a CC organic clutch, which I'm getting to like very much. They are very well made, smooth in operation and cost less than the Helix and AP versions.
Yes, we're dealers for them.

 

id go for 440 bhp

 

With a perrin front mount? I`d be more inclined to say bang on 460 with a lot of lbft depending on the boost target

 

Kind of looks familiar but different to me

I'm guessing 450ish BHP and 475 ish lbft peaking at 1.55 bar on the original ECU. Maybe a bit more with the ported heads/valves etc?

As always look nice and subtle and not too 'blingey'.

 

475bhp

 

450 ish

 

Great job Alan that looks perfect

Is it a 2.5 in these or a 2.0 ?

 

It's a 2.5

 

Of course the power is relative to very specific inputs.
We had a dyno figure in mind which matched exactly what we expected bearing in mind the SC46 turbo chosen.
On the road the MAF figures at only 1.55 bar suggested 480 bhp.
V Power only.

 

That will have some torque then..... I'm stabbing at 475/550

 

Very tidy job, looks spot-on - as ever

 

I can vouch for the quality of this car as is seen it for my own eyes 7.30 sat morning when I was @ ENGINETUNER for an early mapping session with martyn with my blobeye Sti. .
Martyn showed us round the workshop and when I saw this it looked OEM and subtle but with all the Perrin etc and updated goodness.
Looked amazing!
so much care had been taken in my eyes.
He came up behind me on the m5 when going home so we cruised in convoy for 30 odd miles!!.
Reppin the subarus!.

 

I love the black crinkle on the pipes!!! It's def what i'll be having Alan. Unfortunately it looks like now the third engine has fallen through

 

CC clutch? 1st I've heard of them is this the new kid on the block

Out of ccuriosity what does the standard clutch in a 60 plate sti take if not launched off the lights. At what power point roughly do they start to slip or is it to hard to say

 

480bhp isn't to shabby though I bet the owner is well chuffed, what tourqe did it make?

 

It's more about torque really. The 240mm stock item is probably ok at around 400 lbs ft. unless you start launching it. Some guys are ok with clutches and some aren't!
We've fitted the CC to a few recently and it certainly seems to do the job, one 2.5 running at over 500 bhp now.
