JE 8.8:1 pistons and Eagle rods..

There are a variety of setups you can do. You need to search the forum more before making a post like this.

JE 10.5 and Eagle rods.

Yup there are so many combinations/variations. Gotta do your homework and if you have a more specific question, ask then.

10.5s would create alot of knock for a high boost car, you want 450hp be prepared to spend 10k

Why did i turbo a 420a? Why is your 4g63 smoking in a ditch?

I have around 5k-6k spent on engine and transmission. Should be able to hold up to 550+whp. I could have done it for less if I had looked for better deals, but didnt wanna waste to much time.

Your question is kinda general and has been discussed before, but the like Mark said, there are many combinations possible, 8.8:1,9.6:1,10.5:1. It really depends on what you want and how committed you are to this project...

I wish I had blown it, believe me, I do...

Our engines are not that sensitive toward knock (though it is about a good tune). Even at 570whp with 30lbs of boost (on a 10.5 engine), the engine is not knock limited (albeit this is on C-16. But I did the 486whp with 3 gallons of C-16 and 3 gallons of 93. Still not knock limited). There are also a few on here who have run 10.5 comp on their daily (turbo) with no problems.

And no, you shouldn't need to spend that much.

Ive already spent over 10k in parts, and i know you have these cars aren't cheap to turbo right. I dont think hes looking to spend that much so 10.5s would probably be out of he question for him, I didnt say it wasnt possible but without a good tune you will destroy an engine.

Why did i turbo a 420a? Why is your 4g63 smoking in a ditch?

Spent too much if you are just talking about engine and turbo set-up;

Guys have turbo'd these for hundreds. Now with the level the OP is talking, you'll spend more (not $9500 more, but more).

Originally posted by Raine883I dont think hes looking to spend that much so 10.5s would probably be out of he question for him,
He's building his bottom end (i.e. built engine). Whether he buys 8.8, 9.6, 10.5, 12.5 the cost for slugs will be the same.

This is true of whatever comp you have.
