Welcome Jay. Nice looking car and would like to see this go around on a couple of track days.

Awesome guys
So had my STi six speed (2004 forester STi) fitted today along with some new DBA T3 4000 disks and pads.
RSS will be building me a brand new EJ207 based around a closed deck block with forged internals. Will also have refurbished heads with some porting done also. Kelford 272 cams will also be fitted.
I have also settled on a Blouch 20G XT-R turbo. ID1000 injectors will supply the fuel.

It will be running on BP98.

So, whos going to make the first guess for power???? im hoping for 350whp and a high 11 second timeslip to start with.... until the blue bottle goes on

Going to be killer mate, did Maximum Motorsports do the 6 speed swap?

As for power on 98RON, I will guess 347.7HP

Should be close to 340/350hp with the cams and boost depending.

E85 not viable?

Would make the world of difference getting that 20g spinning a bit faster and the torque down low.

Mate I would love E85, how ever, it just isnt common enough to use IMHO. Closest station to me is 40 min away and I cover a fair few km's during the week so it would be a big pain, even if I loaded the car with Jerry's.
My ECU wont support flex either. Its an option I may look at later though

Thought i would update this thread.

So motor has been recieved and consists of following.

- version 8 SCD block
- 2.5L crank (2.15L stroker)
- Nitto rods
- JE pistons
- ARP case and rod bolts.
- ARP 625 head bolts
- new water pump
- sti 11mm oil pump
- OEM gasket kit
- new cam belts, tensioner and pullies.

Heads are 04 WRX heads (big port AVCS and shimless buckets)

- Kelford 272 camshafts and springs
- retaining OEM retainers
- currently with Neil at 'the engine shop' being rebuilt.

ULTREX headers with double layer ceramic coating inside and out and will also be wrapped.

Process west TMIC
Blouch 20g XTR
ID injectors

Coupled to a long ratio sti six speed.

Car will be run on BP98 and the goal has now been reset to 350whp and hopefully break a high 11 second pass, or atleast 115mph

Thanks for all the help from the forum. I feel i have learned a lot from this build.

PS i still have a big nitros shot if i decide tens are in order

That's a long way from the 10 second car you said you were going to build.

Yeah daz, it was definitly some naivety on my part. being new to building these cars and learning alot on the way i quickly learned that 10 seconds was a little unrealistic as a daily driver in these cars (where a v8 its quite easy)
This was never a question of money (as i had 35k to spend on this) it was always avout remaining drivable as a daily... which i quickly learned is unrealistic (every engine builder said the same thing. Will be laggy and a pig). So ill pump it down to tens with nitros for a once off
Unfortunately a GT35R equiped 550awhp car just doesnt work as a daily as you would know.

350 is still a bit of an ask with a 20g on 98 i feel ... but all the best
