I'm not going with a 42R...I am putting on the Twin Scroll s256 which spools just like a 18G on a 2.5L...so it'll be good for any type of racing


We are going to develop this as a kit...so if you want one let me know and I can make it happen

I want one but I don't know if I want one, ya know? I'd need exact costs and a wile to convince the mrs

but yeah, I'm definately a prospective customer for that kit. I'd want a smaller twin scroll though and I have an EJ20... not sure how different that would make things...

Well....here's the deal now...I throw a Valve from my EJ20 heads to my Forged EJ25 Block....it is the Suck

Soooooo I have decided to rebuild everything..

Soooo the build just got bigger; We are going to have a forged everything, steel sleeved....etc....cams...etc...point blank probably the highest horsepower WRX in the state when we are done...process begins in a couple days, going to be insane! We are shooting for 500-600whp with this new set-up...NO2 free too :)

I will keep you all posted.

Actually there are a few 500 and up subi's in the state.... I know of at least 2 in the springs alone. Check out Revolutions Performance's STI it has around 550 at the wheels.. But anyways I would like to see this thing when you get done since we are essentially neighbors.

*NEW MOD

This started out as a simple turbo swap but a few nights ago I threw a Valve from my EJ20 heads in to Forged EJ25 short block...I don't know exactly what the damage is yet (we are going to pull the motor Monday or Tuesday) but I just went ahead and got all new parts for this build and I am going to sell off everything that is not damaged.

I don't plan on this build being 100% done now for another 7-8 weeks or so...but I will keep you all posted and post pics
