building my new motor

i'm about to rebuild a 2.3 for a turbo car,


this motor will be able to sustain HUGe amounts of boost....

like 20-25 LBS

i want a trqy cam, 8.9:1 comp

what type of pistions do i need??

and i'm getting the block blue printed and balanced and all suchnot's

this motor will do 10k !! rpm or so i'm hoping,

the crank is a light weight crank....shaved....but where can i get it ?!!    let's just say money isn't the problem here..it's where to get the parts. !!

Money isn't an issue? In that case, my friend, you need to check out Esslinger. They have lightweight 2.3L cranks for about $1500 or so...

Also, the stock turbo pistons & rods will hold up to 20-25 psi. The factory dished, forged pistons give an 8:1 CR. However Esslinger has aftermarket rods & pistons I'm sure they would be more than willing to sell you as well...

id stick with the stock compression personally, with as much boost as you want to run, the factory compression works very well, im running 18-20 psi on my stock turbo, injectors, and compression ratio with no problems, other than my turbo wanting to commit suicide

even the fast guys across the boards run the stock compression ratio, because it works very well
It's Gumby's fault.

if you plan on turning 10k or more you should be ready to spend 10k or more... esslinger can help you out with that.

the only problem with Esslinger is that theyre so expensive, you get what you pay for, but its just a bit time expense

AM has alot of stuff to help too (Shameless plug alert)! Anyways, I 'm actually in the middle of building a very serious motor (~350 HP/425 FtLbs) so I'm going through the what to but and what not. My professional advice is DEFINATELY new pistons, Summit carries some very nice Sealed Power forged dished (9-1 comp ratio) with coated skirts. Racer Walsh sells Crower Sportsman rods, stick with the 2300 larg-journal (turbo) crank though, there has been a rash of stroker failures lately. ARP main and head studs (we have those), good oil pump, Fel-Pro gasket kit (we have those), should take care of a very nice, stout bottom-end. Essy's aluminum head is pricey, but it flat works, get the big valve competition version with a good roller cam (make sure you repeat the phrase "turbo motor" to them at least 25 times or they'll send you an N/A head, and get UNDERCUT studs for the al head). Stock intakes work fine, just match-port them, same with the TB. Nobody makes a header that doesn't crack and the E6 manifold is very good, buy some carbides and hog it out (not too much, you want to preserve exhaust velocity as well). Turbo, call Scott at S&R Racing for a recommendation, and a clutch. Go with a Vortech Aftercooler in place of the stock IC. Then build the rest of the car to handle the power. Obviously your going to want an aftermarket computer/injector set-up.
