More bottom end internals and turbo size Q's
 

This is for a "daily driver" 6 speed manual 93 RX7 (~2800-2900lbs). I've got a 370ci iron block (4.030 x 3.622), stock crank, ported and polished 317 heads, ported LS2 intake, Holley 90mm TB, truck manifolds, and I'm about to order eagle h beams (6.098 length ok???) TBD pistons (leaning towards -15cc diamonds, which would be ~8.9 cr I believe) and I'm still workin with the local cam guru, but so far it looks like 22X/22X .590/.583 115. I'll be running 93 pump gas and meth injection... My power goal is 700-750whp, on 93 octane and alky if needed, and I'm not sure how much boost I'll need for those numbers or what RPM I'll be able to spin it to... With that being said, what size NON BALL BEARING turbo would you suggest and what ar, I want quick spool up, not like a supra dyno sheet, and I don't want the turbo or motor to choke up top. And are my piston cr and manufacturer and rod length ok?

I hope thats all the info you need, if not, please let me know and I'll try and furnish the info. Thanks in advance!!!

To reach those #'s on pump gas you'll need a nice decent size unit. Probably around 76-80mm range.

I was leaning towards t76. What ar would you reccomend?

.96A/R....and no less.

So would your Turbonetics TC78 F1 Trim do the job?

Yes, it would do the job.......

Hopefully I will be able to tell you how that turbo works on a VERY similar setup in a few days...

The Eagle Rods are a good choice. We can give you a great deal on a set of K1 Technologies Connecting rods. We do have the equipment here to balance your rotating assembly for you.

Not matter how good the internal parts are, if the block is not properly machined and assembled it will usually result in a premature failure.

Shoot me a PM and let me know what you are working with and I can see what kind of deal I can get together for you.

Thanks,
