Default ej22t build

UPDATED APRIL 17, 2014

Alright, so I ended up cracking a piston and am losing a lot of compression....my ej205 is on it's last legs.
After a lot of reading - I've decided to go with an ej22t build and wanted some advice as there are a lot of different routes to go down with this build.

My current plan is as follows:

EJ22T block halves - stripped down, cleaned, honed, balanced, bored 1mm (0.04")
OEM STi rods (from what I gather they are strong enough for 400whp)
JE 98mm pistons
S20 WRX heads with quick PnP & Stage 2 cams OR stock D25 heads out of an EJ255 2.5L WRX
OEM Phase 1 75mm Crank
ACL race bearings
ARP headstuds
Timing belt kit/tensioners/pulleys
11mm STI oil pump
Headgasket = K601M975

Any help or input would be greatly appreciated!

My plan is as follows:

ej22t block halves - stripped down, cleaned, honed, balanced, bored 0.020mm and checked for tolerances, machined for #5 thrust
OEM STi rods (from what I gather they are strong enough for 400whp)
Wiseco 97.5mm pistons (0.20mm overbore)
ej205 heads (well ported, polished)
ej207 phase 2 crank
ACL race bearings
ARP headstuds
Timing belt kit/tensioners/pulleys
11mm STI oil pump
Headgasket = ??

I'm kind of confused now as to what the final CR will be. I know with ej205 heads I will get a low CR, of about 7.4:1. Will the Wiseco 97.5mm pistons over come that or will I need to go custom pistons?

Any help would be greatly appreciated!
K601M975 used with .024" head gasket will give you a static cr of 8.38 to 1. Je makes a piston with smaller dish that will get you around 8.58 to 1.

Thanks!

I just found this kit online - seems like a great deal on JE smaller dish pistons + Eagle rods deal. Otherwise the pistons themselves are around $550.

That's what I figured. I'll just stick with OEM STi rods. Are there any specific years that I should know about, being stronger/weaker than others?

Ok so I've updated post #1 to reflect the current parts that I have purchased and near-future plans for block to be assembled.

Can someone chime in in regrds to my heads dilema? I can't seem to decide whether I should re-use my stock S20 heads and get them PnP'd with a fresh set of Stage 2 cams OR get my hands on D25 heads, leave them stock, and just use those.

Also, this will be my track car and perhaps auto-x. As a result, I want to chose the best turbo for my application. I want the best of both worlds, if possible. I have recently picked up an AVO450 turbo. With a built 2.2L and some boost + timing thrown at it, I can expect full boost around 3400-3600rpm.

Is this an OK choice in turbo for track AND auto-x or is it too big?? Should I go with something a bit smaller, like an HTA 68 or a Blouch 20g xtr? I'm not too familiar with these new billet turbos on the market, until now I've been scooting around in my EVO3-16G setup hah hah.

Input please!
