Turbo CRVTEC Question

[97HCiViC]

I was planning on building a CRVTEC motor for my car. I want to make it F/I so i was wondering what is the ideal compression ratio for the motor?..? It's a b20z block with a b16a or b if i can find one head. Also i was wondering if there are any special parts i need and such. Also any info if anybody has built one for turbo. Thanks! -97HCiViC

How far are you wanting to take it? How much you willing to spend?

[97HCiViC]

I have about $8,000-$9,000 dollars to spend and i want to get it to at least high twelves or low thirteens

a stock crvtec and 10 psi should get you too your goal

and if you want to build up your enigine 9.5.1 cr and maybe sleeves if you wanna go over 15 psi

[97HCiViC]

What ratio should i go if i want to run at 10 psi?..? And also what's a good turbo to use?..?

get a big hairy T3/T4 turbo with $9K you can easily get a turbo kit and build up the block to get you into the 13's. I think you're biggest concerns will be forged rods and pistons, resleeving the cylinders and getting the block decked. That should give you a pretty strong block so you can up the boost at the track. I suggest you run somewhere between 9.2:1 - 9.5:1 CR. A lot of other things go into calculating CR, so just try to get it somewhere between those two numbers. That way you aren't a total dog off of boost. However, you can run semi high compression and still have a reliable vehicle as long as it's tuned properly.
