I've pushed ~600whp on my girdled Gen 3 2.1 build. I wouldn't see even a non girdled Gen 3 giving up at anywhere around that power level, but who knows.

cmiller8006 11-19-2014 10:49 AM

I really doubt that the girdle helps the gen 3 much if any at all. The gen three has the benefits of the girdle and better cooling capabilities. But with that said, I don't see either breaking at 650, I was prolly in the 560-580 range at Chicago.

InfraRedline 11-19-2014 10:55 AM

Yeah that's why I said I don't see even a pistons/rods only Gen 3 having any issue. GM seems to have nailed it with the block design.

I want radials instead of slicks but I'm still debating it haha

Which cylinder is farthest away from the timing chain? I'm guessing it's number 4. The way the gen 3s are laid out that appears to be the weakest cylinder I would say just by looks.

Well snit. I thought cylinder number 1 was by the tranny. :lol:

#4 is next to trans

The compressor map will be different with the .63 housing. It'll choke up for sure and never reach peak flow. I'm going to aim to get it working on pump gas first, make 500, and then up the boost. 600 or disappointment lol. I figure the block can take 700whp and 45psi with ease.

sorry for creeping through your posts haha is 45psi deemed safe on the Gen3 block? I was curious as to the max boost I can run on mine as well , I figured 35psi consistently and a 40psi run a few times

raver0789 11-20-2014 08:16 PM

This was my gen 3 stuff that was going together but I sold it to buy cmiller8006's block. The guy who bought it is putting it together and this is his now. Boost isn't the issue it's detonation that kills these motors.

gotcha , I was just afraid of cracking/blowing open the sleeves in my gen3 block from running too high of boost. Thanks for the quick reply !

Towed the truck up north to get the kit fabbed up. It's gonna be a tight fit in the engine bay for this turbo lol.

Nice

raver0789 02-09-2015 03:53 PM

Well ran into the first problems. There always are when doing a build :)

The motor i bought from cmiller8006 uses the ati damper. The sky redline's power steering runs off the stock damper on the car. I was talking to omiotek about this. Either i can run the stock pulley (I rev to 8k and have stage 3 lnf cams. I want the motor to last, stock damper is probably not a good idea) or i find some way to run the cobalt system. Or I run another aftermarket damper. Anyone have any thoughts and insight?

You would think I would have seen this coming :D

Cheers.

Old mr2 had an electric power steering pump that would be an option you could make a couple custom hoses and be ok. Also you'll save a couple hp!

raver0789 02-09-2015 06:16 PM

Argh. These things never go smoothly. I was told the cobalt one won't work because it uses the bcm. Is this the case?

I believe you are correct.

Omiotek 02-09-2015 10:32 PM

dude I told you it wont work due to the bcm and if you get any of the electrical wrong you will pop fuses left and right or the car will not start what so ever. Its a lot more complicated then you think and you will probably want to kill yourself trying to figure it out.

Call ati and they should be able to help you with a drive setup. most of that stuff is custom made. you should be able to get something that bolts up to the dampner itself. that's how the fluid dampner setup is.

they will make your anything you want

raver0789 02-10-2015 12:08 PM

You did tell me, but I figured I would ask around as well.

I will be calling them, thanks.

raver0789 02-10-2015 12:25 PM

They are going to try to make a custom pulley for me, I just have to get it all measured up and send it over to ATI. Thanks Omiotek.

Omiotek 02-10-2015 12:32 PM

Welcome. I'm sure they can do it. I've seen a lot crazier custom stuff done by them

raver0789 02-10-2015 12:51 PM

Yup. It's just time frame. Gotta get the ball rolling asap as it's gonna take at least 60 days to get the custom part made.
