Hello Guys,
I have a Subaru STi GC8.
I just got it a week ago.
Now in my country i have many evos.
And some scoobies, So i would like to mod my scooby upto 500BHP.

I used to have an evo 8 MR but i transfered to subaru. once i drove my freinds gc8 i fell in love with it.

Now to the point my gc8 is stock and i would like to know exactly what i need to get that mark 500bhp so i can bully evos around.

HOw muc $$ am i looking at here .

Cheers
Mudi.

 

Short answer?
For a reliable 500bhp including engine rebuild, 6 speed gearbox, brakes, turbo, etc. I'd say probably anywhere between £13-17,000 if you're paying someone to do it for you.

Say £2k for a 6 speed, £2k for a turbo, £5k for an engine rebuild, £1000 for an ECU then all the other bits like hoses, exhaust, induction kit, intercooler, headers.
And then labour. Those are all very finger in the air prices and based on new parts.

Obviously if you buy parts like the turbo, intercooler, exhaust etc second hand you can save quite a considerable amount in that area but unless you know your stuff I'm assuming the engine rebuild and 6 speed fitting would be left to a specialist.

HTH

 

Be far cheaper just to buy a high power impreza ready built

 

for a true reliable 500bhp then its gonna be way more than that.

 

Hello guys,

My GC8 is already a 6-Speed the previous owner had changed it. And plus iv already bought 4pot used Brembos off ebay.

I have a freind who is a specialist mechanic so probably he'll do it for me for free basically coz were close freinds.

So now i would like to know exactly what ill need like which turbo ,ecu etc

Cheers

 

I did wonder, but I guess it depends who you go to - RCM would probably be the daddies of the bunch, and I'm sure in their case my figure would be way out!!

 

anyone else

 

Stick a v7 jdm short motor in there, either mdx321t, sc42/46 or something similar, fmic, injectors, 3" exhaust, fuel pump, 3 port boost solenoid and uprated filter and cold air feed, that should see you 450+ on the right set up, bearing in mind that's a stock bottom end so much over that and your on the edge of known reliability, that's the cost effective way.

Want a solid forged motor which is rated to 500+ and your talking a few quid.

If you want a "safe" 500+ rated bottom end, I'd say budget a minimum of 5k basic for starters and that's without anything else to go with it, and then you may want to consider head work, valve train etc list goes on and can quickly become a money pit, if you got the cash or a friendly bank manager then go for it

 

Yess i had a chat with a specialist... im fully forging my motor...hes gonna give me the quote by next weeks,,

And all them evos going doooooooooown

 

It's a lot of money to spend to beat an Evo tho, especially the modified ones good on you! Have fun

 

thanks mate..nah in my country evos are not modded all of em are stock.
time to kick evo ***

 

lol is this guy serious?

 

bro when i say somethng , im always serious.
went to a specialist he quoted be about $20k. all even including the turbo and ecu...
Its a huge huge list.

 

22b lump, syvecs ecu ,clinic turbo, and a dam good map sorted.
then 6 speed box and diffs, brembo brake kit conversion.not ness in that order.
