2.8 to 305 swap ...

My friend is going to do an engine swap in his thirdgen, Its a 92 2.8L Camaro. The engnine he got is from a Grand Prix, I forget the exact year he said. He has the complete engine, all accesories. No Rad for it or AC condensor, can he use the one on his car ? Also, what all is involded in doing the swap? He said he talked to a mechanic who said he would physically have a hard time fitting a V8 into his car , I seem to think differently. He has the motor mounbts too , shouldnt almost everything bolt rite up ? ... I could be wrong so dont quote me on this , but the grand prix was a 1983-85 , dont remember exactly if that helps. Also he got the Trans with it, its an Auto , so is his Camaro tho. Can he use the same driveshaft ? And isnt the rears in all thirdgens the same ? Or well in the 92's ...

if it came out of an older grand prix, it's not a 305, and whatever it is (probably a 302), it's an underpowered pig. When he finds out the major expense he's got to go through to put a V8 into a v6 thirdgen, nobody with any brains would go through all that expense and time to put in such a crap motor.

Putting in a 350, although still cost prohibitive (compared to selling the V6 car and just buying one with a v8), it's still WAY easier and cheaper than screwing with that old Pontiac boat anchor.

I'm with Jim on this one...your friend should have definitely saved his paychecks and looked into getting a new or quality used 350...sink right in, and would be cheaper to install...now you have a lousy engine that's going to give you nothing but nightmares...good luck with it though

I agree with these guys. I looked into an engine swap and besides having a 305 (assuming it is that), you need a new transmission and ECU. For the money of installation, just get a 350.

Thumbs down

Well said jim, josh, and garage inc. They are all right. Save your buddy alot of time, money, and headache and advise him against it. Sell the V6 and pontiac motor. When hes done he'll have enuff money left to buy a 350 camaro. He would need alot of new things to make that motor work in there not just motor mounts. And only chevy motors go into other cars not other motors into chevys! I mean hell i bought my 85 305 tpi IROC for 1200 it screams and its almost mint! U just have to know where to look.

Im not a big pontiac fan , my bad , he told me it was a 305 from the prix tho so i guess its his screw up now lol ... At any rate , he got the engine, with the tranny , and a few other parts for like 500$ ... and he wanted to get a 6 and do the wap so his insurance isnt gunna sky rocket ... I told him jsut buy an 8 hehe ...

Best way to **** a 6 cyl owner off ... " Hey you got a V6 Camaro ... I bet its REAL NEAT ... " haha the kid snapped and threated to brick out my windsheild , which is currently the broken one anywasy form when i bought the car wrecked so i dont give a **** lol

It would be a Waste of Time, Effort and the Money putting any V-8 in a V-6 car. No matter if the engine was free. Not a very compatible swap, so I would just drive the car as is and forget the transplant.

Yeah, well... when you taunt them, sometimes you've got it coming. Karma is a bitch.

Anyway... back to my V8 rant. As said above, putting a 305 in is bad enough, but you've got a Pontiac motor. This means your buddy is going to be making his own motor mounts, and when he gets to the transmission and finds out that NOBODY makes a BOP transmission that you can hook the stock torque arm to, your buddy is going to start feeling pretty stupid. I'm not sure if the 200R4 in the TTA uses the BOP bolt pattern or not, but whether it does or doesn't, he's going to be laying down some MAJOR cash for a transmission that works in that car. All so he can pimp around in a motor that maybe makes 150hp.

It probably is a 305 Chevy if it is out of an early 80's Grand Prix.

whoops. According to one source I found, starting in 83, all V8s in the grand prix were the LG4 305.

Still a pig of a motor though.

This source says all v8s before 83 were the Pontiac 301... which makes more sense than my first sources that said 302s, since as far as I know the only GM 302 was the one they put in the 1st gen Z28s.

Ok i talked to the kid and found out what all he has ... My first post was pretty off with the details but here i go again lol ...

1992 ***3.1*** V6 Camaro , Auto

Then engine tranny and driveshaft he has is from a 1984 Grand Prix ...

Engine is a 1984 Carbed 305 ...
Tranny is a Turbo 350 ...
Driveshaft is the one from the grand prix, so wouldnt it be too long ???

He has the complete engine with the mounts btw ... So what all would be involved ? He got the engine tranny and drive shaft for a couple hundred bucks, and NOW after he buys the **** he wants to know how hard it will be to install , What is and what isnt compatible ? The 305 has all the accessories with it ( Alt, AC, Power Steering Pump ... ) No Rad or AC Condensor, will the old ones from the 3.1 work ? Probly not rite ? ... He also has a Flex Lite Fan for it ...

Same answer as in all the other Posts, " FORGET ABOUT IT".... IT STILL MAKES NO DIFFERENCE....Or better yet just rip that 3.1 out and try making that bad boy 305 work and find out you now have a car that can not run. "Live and Learn"

I understand its not gunna be no rocket, all he wanted to know was would it go in ... What all mechanically is involved in putting it in ? He already has the engine, and he is goin to put it in , he jsut needs to now what all has to be done ... I've told him 100 times sell it and get a IROC or something , but he wont have to it ... so at this point its not a matter of Go sell it and buy a V8 car instead, he wants to put it in , and thats what he plans to do, he just wanted to know what all is involved mechanincally in making it fit.
