Here's the deal. I put a turbo on my 99 cavi. I went to visit some family. I didn't tell my roommate about the oil leak that I had to fix and he borrowed it. The next thing I know I got a blown (not in the forced induction sense) motor. So I got a used motor put in it by a local shop because I've been too busy to do it myself. Now I got a blown motor, a turbo, all the goodies that go with it, and alot of time to work on it through next summer. The motor isn't too bad, just a rod bearing and the damage created from that, so no holes or anything. So I'm gonna rebuild... reanimate... revive... my blown motor. I was wondering what some of you put into your motors when you built them up for forced induction. What type of pistons, rods, cams, etc. Also what else should I get for my setup? wanting around 250 to 300 HP.
Heres what I have so far:
Garrett T3 turbo
internally wastegated at 7.5PSI
BOV
log style mani
downpipe
cartech adjustable 14:1 FMU
RC engineering 310cc injectors
intercooler
colder spark plugs
cometic head gasket (.74 for boost)
performance lower motor mount and upper insert
oil return and supply
all vacuum lines

if you spun a main bearing I would consider that block NFG, also the crank is probably NFG too, but I can't be for sure.

Unless the car was shut down immediately following the spun bearing, I think you may have to look for another donor engine.

yup time for a NOT blown junkyard motor.... I got a stock head from a junkyard for 75 and it was guarenteed to work.....

Good luck

Lee.

I was told one of the rod bearings was starved of oil. The chevrolet shop said it was knocking slightly and that rather than replace the bearing it would be better to put a different motor in it just incase something else was starved that hasnt reared its head yet. I don't know that much about internals and everything but I'm gonna work closely with a couple engine shops in town. The first thing I do when I get some spare time is strip it down and take a look at the internals and have the shops see what they think, but from what I've been told it is rebuildable. Thanks for the input though. I'll take a close look at the block and everything.

You've got the right idea. Measure everything. Check cam bearing journals, rod and main bearing journals before planning to use the parts again.

Was it #3 rod bearing?

-->Slow

no it was the #1 bearing. The guys at the GM shop said that it is often the first to go when you run it with low oil. but they might have just been talking out their asses. They don't always seem to know as much as they claim. Plus one of the guys working on my motor swap had just been fired from the ford shop! but it runs now so its all good.
Can't wait to start pulling that 2.4 apart!

well you may wanna consider a 2.3 oil conversion. best insurance on a built motor you can have imo. many people on the org have done it and theres quite a few post about it so take a lil time to search and think about doing that too.

just because you spun a rod bearing does not make the block junk........ probably the crank though.......

yeah the crank might not be usable, but the block is probably very usable. you could always have it line bored and get another crank. you can get a factory forged steel crank for $180. your cam jounals should also be fine.

What are my options for good places to order quality aftermarket internal parts. I've checked cavalierconnection but havent looked at too many other places. Also, I'm planning on using a cometic head gasket made for boost. Should I use 9.1:1 pistons or 8.9:1 pistons along with the head gasket so it still runs smooth at low RPM but handles the boost well. And I tried to find some info on the 2.3 oil conversion, can anybody who has done it help me out, or if I was looking in the wrong place maybe someone can tell me a topic to read through about it. Thanks

lesson learned.... always fix oil leaks.
