300+ horsepower on copper gaskets?
As long as you guys have also, rebuilt your engines with forged pistons, rods, crankshaft, ported cylinder head etc, then that's ok.

It think its a bit risky recommending parts and products, if its not installed on your car and tested it yourself.

I've just gone through a different direction with my engine rebuild.
adding a multi-layered metal gasket, this only cost $150.

just my opinion.
Because it cost me a lot of money for the rebuild on parts/labour.

Dont take shortcuts!

 

I don't plan on going past 300whp, but I know the T28 is not going to be able to make it there. I just want to know if the engine will be able to hold it or not.

 

engine can't handle that much psi/hp without being rebuilt/strengthened.
cooper gaskets are rated at 10psi -16psi.

for turbo.
garrett gt28rs 250hp, garrett gt2871r 350hp, gt3076r 500hp. (approx hp ratings).
T25 flange, same as a t28.

recommend to install a multi-layered metal gasket on the engine for safety.
rated for 20psi+

previously, on my car with copper gasket it cracked and end result was damaged bent rods.

Check with Dennist99.
from his explanations, He's car must be a rebuilt engine also with copper gaskets.

 

i dont think you notice how he said he was REBUILDING THE ENGINE WITH UPGRADED PARTS

 

The stock head gasket with ARP head studs will be fine to hold 300WHP and more.
I am running a stock head gasket now an dno problems and im gonna soon install my ARP Head studs just in case because im at 19-20psi now

 

i stil lrun the OE Mhead gasket... i didn't even open up the engine yet ;-)
just threw in most N/A stuff i could without actually doing engine work ;-)

engine work is the next stage ;-)

 

Talked to Rodheavers (http://www.rodeheavershotrod.com) yesterday. It seems like I will be able to get more from him for some more money. Here what he broke it down too:

Balance-150.00
Shotpeen and Polish Rods-75.00
Bore and Hone-120.00
Magnaflux Block and Crank-120.00
Debur Block-75.00
Knife Edge Crank-50.00
Port and Polish Head, Polish Valves-300.00
Check Decks, Debur if Needed-150.00
Clean and Assembly-400.00
Blueprinting-150.00

Total-1,650.00

I would need to provide new springs and retainers, crank bearings, flywheel, gaskets, and pistons.

I'm pretty confident I am going to go this way. The work seems great for a reasonable price. So, just need to decide from here. Thought'

 

yo guys, quick question, does anyone make a beefy crank for us? or are we stuck with having one custom built for us? Cause i know theres no way our stock crank could take the abuse of highhorsepower for too long right?

 

Stock crank is supposedly good for 600+ whp.
