Hopefully this isn't in the wrong forum:

I currently have a 383 with Eagle forged internals that was used with my D1SC setup that I recently sold. I was heading the NA route when I had a change of heart(call it boost withdrawals). My question is this:

Can I use the Eagle crank and rods for a T76 GTS build or would I need to use a smaller turbo(T67S) and keep the hp at a certain point? I'm thinking that I would need 925 hp to run in the high 9's with a 3500-3600 lb car. I'd like to use parts that I already have knowing how expensive this is going to be($3500 for the PTK kit, $1,695 for the turbo, $$ to upgrade fuel system, new tranny, new cage, etc.). For those of you who have gone through the aches and pains of parts breakage, please give me some insight.

How high can I go with the compression? This is a street car but will spend more time at the track than on the street. I don't have to run the RPMs up real high to achieve my goal which I would imagine would help in the parts department.

Can this be done with stock ported heads or do i NEED to go with bigger AFR heads?

 

This should really be discussed in the Forced Induction forum.
Transfering, thanks.

 

Those internals will take all the 76GTS can dish out. I'm using the same components with a custom PTK T88 kit. BTW I'm running mine at 8.5cr.

That's music to my ears.

Thanks for your reply.

 

So you guys like the Eagle for 800rwhp+?

 

Local buddy of mine is running 5.4's@137 in the 1/8th with Eagle 6" rods, and Eagle crank in a 377, and tons of spray. Don't see any reason why I need anything different. 4340 is stronger then people give it credit for....

Its not the fact that is 4340, its the fact that eagle is chinese and the others in comparison are american...

I just trust american grade steel a little bit more than chinese from experience.

 

If what you guys say is true, it bears to reason that one is a theory(opinion) and the other is fact. I'll take proven info over personal opinions any day of the week.

Not to say you haven't had bad experiences with Eagle products, Highlander, but I'd like to hear specifics.

Maybe a few more could chime in?

I once was told you couldn't run 12 lbs/boost on a stock LT1. I did it for almost two years while going through tuning issues, fuel issues, etc. It only gave up the ghost when I sprayed on top of it. Why did I do that? To see what would happen.

Oh, by the way, I ran 15 lbs/boost with 10.0:1 compression in my 383 for a full year.............almost a full year...........lol. That's with **** poor tuning on my part. Slightly hurt the #7 piston. Block and heads are O-ringed so head gaskets weren't being blown weekly. If what I put the car through for that time period only hurt #7, I'm a believer in the notion that "some people play it TOO safe."

I'd like to do this project RIGHT but I don't want to play it TOO safe(spend more than is necessary).

 

From my experience in construction....

I guess the eagle will do then...

 

They get their steel from the same place we do. I'm not a huge buyer that just because it's made in the USA it's quality is any better. All the equipment used to make Eagle parts probably came from American vendors... Automotive parts are only "in print" or they are not. I doubt Eagle would be in business long if their parts were junk. BTW my bottom end is made from Eagle as well! my $.02

 

maybe... maybe not... there is got to be a catch that one crank costs $400 and the other one $800.

anyways... I will stick to it and see how it holds

 

It's called "capitalism." Ever wonder why that $99 orange dicer "ONLY COSTS $19.99 IF YOU CALL TODAY!!"??

Create a sense of NEED and people will NEED IT.

There's a 700+ rwhp STOCK LONG BLOCK turbo LS1 now. Why? Because they said it couldn't be done. And he said......."really?"

Just like the 540ci motor in the Camaro that everyone said "it won't hook, too much torque......." It hooked.

Not knocking you Highlander, I respect your opinion. I appreciate your input. I prefer your opinion to those that are reading this and won't say a word. Somebody's personal opinion or experience is what makes this board what it is. If I fail in my attempt to do what you said wouldn't be smart(you never said it couldn't be done, just not smart) then I will post my failure as I would my success. I always have.

Wish me luck!

Besides, I've never broke a crank before.........or ever hurt a rod. This could be something to tell my children about....................

If I break something it's all JZ's fault, lol. j/k.

 

Slo-Ride,


That's kickass that you're going Turbo. I hope finally that you'll be able to hand me my *** like you've wanted to do the past 3 years....just pray you have your's done soon.


You know I'm just giving you crap. Your car is going to be down right sick and I can't wait to see it run

Like you, I'll soon be switching to a T67(min)-T71 on my car.

Good luck with your project bro, and keep me updated on what is going on.

 

Man, I have broken lots of stuff. You must be lucky or something.

If you are talkin' to me, I'm a little lucky, but I also keep my a/f ratio at 11.8~>12.0:1 on the street. I'll give up a little power to keep my engine alive.
