I an going to go turbo in my ep3 and was wouneding if anyone made internales for the k20a3 (rods, pistons, sleaves, and head stuff) for our cars. If not an places that custom build stuff would work to. How much boost could i get away with (safely) with rods, pistons, and sleaves.

Check out Cybernations Stage 2 and up kits (http://www.cybernationmotorsports.com/). Pretty sure that comes
with new rods, pistons and some other goodies.
Not sure about sleeves, I think some guys at honda-tech were working
on making them. Pretty sure you could get nasty boost with that sort
of setup.

Cybernation has their own Pistons and Rods for stage II. They have Valve Springs and Retainers as well for Stage III and IV. You can just as easily call them and order them for yourself even if you don't buy their kit. They do sell them seperately. Their asking approx $1,000 for the pistons and rods shipped right now.

Their are also Darton Sleeves available for the k20a3. Cyberbnation is using them for their Stage IV installs.

Right now Stage II is Rods and pistons and about 25psi of boost.

Add the valve springs and Retainers to go to stage III and your good for 30-40psi.

Stage IV is 45-50psi and in Cybernations case requires a new Turbo as the one you get with a Stage I kit is only good thru stage III.

In the case of Greddy, you may only make it to stage II with your turbo. I'm not sure of the specs on Greddy exactly but I'm of the understanding that your T08 is smaller than our T3/T4 and spools faster, yet puts out less boost overall (you max out at like 30psi and we can make 40psi).

Well, hope some of this actually helps ya ;)

Well, stage II is rated at 200WHP over stock (about 330WHP) and stage III is rated at about 300WHP over stock (about 430WHP)...

Not exactly sure what psi that's at tho... I'm guessing max psi for that stage...
