DO NOT PURCHASE ANY REMAN ENGINES FROM PROFORMANCE.....
Im on my 3rd engine in 3 yrs. from these yahoo's and the 3rd one just crapped out on me with less 8k miles on it. The first 2 I got about 35k out of them. Now the warranty's out and dont know if their going to stand behind their product. Waiting to hear from them. 1st one had a wrist pin going bad in #1 cyl. 2nd one spun #3 rod bearing and burnt a hole in #4 piston. 3rd one is knocking in the upper engine area like a broken piston. I had a 3 yr/ 100k mile warranty and havent even got that many miles on the car since the first engine swap. They had no problem paying me the $450 to swap their engines or sending me new ones but I'm getting tired of putting engines in my work car. Anybody used these people and if so what's your experience been with their engines. Im wondering if their really giving me a vin. 1 engine and not a regular 3.8.........:confused:
 


if they gave you high compression supercharged motors you'd never know.

but you'd chip pistons before anything else.
 
kinda what im thinkin. Gonna pull the pan down to look for broken piston skirts. If thats all(cuse broken skirts will sound like a bag of hammers in engine) im just gonna order some pistons and go from there.

Update.....
Proformance is not and will not stand behind this engine since it's 2mths out of warranty. They said the engine with the spun rod bearing was from abuse and neglect. I haven't drove this car hard in over 2yrs. How could the engine be oil starved and be my fault when I used THEIR OIL PUMP they sent with the engine. See what my laywer has to say about it and proceed from there.

Keep it between the ditches boys!

For the amount of work and $$ you have to do to install new pistons, etc. in one, I'd sooner just get a used L32 and install that. Plenty of good used low mileage motors out there. Besides, if the piston is chipped/broken then you may well have scored/damaged the cylinder wall as well. It sounds like they aren't building these very well assuming regular maint. is being done after install.

If its out of warranty then you are probably SOL. Been there done that.
 
Done every swap myself(thanks to the lift in my shop) in about 9 hours apiece. Wondering if they actually put hyperetic cast pistons in these engines and not the forged ones in the L32 engines. I can have the cylinders bored and sleeve if need be but I've tracked a 60k engine out of an 04' for $800. Time will tell.
 
Non S/C engines dont use hyperetic cast pistons cause of the cost involved. Check it out at a GM dealer if you try to order pistons.

they're powder coated........

still not forged lol

Besides, ZZP has made sub 10 second passes with a factory non forged short block.
 
Try sub 9's...they went into the 8's on a factory block before they tore it apart and started upgrading internals. Only thing they had on it were studs (head/main)

That's it IIRC.

I don't ever recall seeing anything indicating that the pistons are anything BUT hypereutectic. If they were forged, I'm sure that someone would have figured it out long before now. you can set a forged piston beside a factory one, and visually tell the differences simply by color.

L32/L67 pistons I don't think are powder coated either, they do have a type of coating on them to handle the heavier abuse of the supercharged application.
 


Well to get off the piston debate which I could care less about. I'll just order a set of pistons from GM hyperetic or not. Atleast I know I'll be getting the right ones.
 
UPDATE:
Found all the engine parts on Northern Auto's site. And apparently is something different with the pistons between S/C and N/A. 2 different part numbers from Clevite. But anyway, $55 a hole or I can just put together a rebuild kit for about $500. Atleast I know it'll be done right and if something does happen to the engine this time I'll only have one person to blame.
