1G 9:1 compression, what can it hold?

[SRTNemesis]

I'm going to buy a talon locally, the owner claims the car has a bent rod, I'm going to inspect it today. He also said he checked the oil pan and there is no metal in the pan. What kind of power can this car hold with 9:1 compression after the rod / piston is possibly replaced, planning to run T4 or 20g turbo?

The car also has 13 miles on a new motor, please check the list below and tell me if its worth getting.

* 6 bolt JDM 2.0 Liter DOHC Engine
* Ground crank .010"
* New oil pump
* Wiseco Forged Turbo Pistons .020"
* 9:1 compression
* Balance shaft eliminated
* JDM DSM Cyclone Head & Cams
* 2g Throttlebody elbow
* Custom Ram-Air Intake
* Custom FMIC
* Dave Brode UICP
* Dejon Tool 2.25" J-pipe
* 2.5" Mandrel bent Intercooler piping
* B1G Limited Slip differential

BTW, properly tuned I'm looking for 400-500whp.

as long as you got the proper fueling and timing you'll be ok,let not forget proper tuning.

I wouldnt expect that to last very long. The are nitrated and when they are cut like that it gets rid of that and just leaves you with soft metal. Good luck.

Yea I never was a fan of grinding dsm cranks. I got one from a junkyard for $50 that was still standard size and just needed a polish. I think the coating is .015" thick?

 

[iwantawd]

it doesnt really matter cause its hardness decreases. so as soon as the outter layer is ground off, no matter how much, it is weaker and i wouldnt trust it.

i was under the impression the coating was .05 thick...

I always heard .015" ... maybe you're right though but that seems very thick.

Either way I would just replace it for piece of mind. Why spend all this money then have your crank take a shit becasue it was turned?

What he ^^ said.

So basically your telling me this motor cant hold shit for power?

The tech that built the car said with proper tuning it can hold the power range I'm looking for 400awhp and a couple other local DMS techs I asked said the same thing with proper tuning.

No basically you posted about the engine and you got an answer. If you wanna believe the local "DSM techs" then that's up to you but really why risk it I agree just get a different crank and be done with it. Why build a motor half way.

Did they know the crank was turned and that takes away the best part of a stock DSM crank? I bet they didn't. If you want to use go for it, it will hold power and I bet it will last a decent amount of time, but why take a chance is all I'm saying. Do it right, do it once.
