Well some of you know that i have been looking into putting an LS1/LS2 or an LT6( i think those are the proper terms). Anyways i have been doing some reading here and there and i came across a friend who is willing to seel me his motor out of his 91 pontiac trans am. He mentioned that it was a small chevy block and i believe the term he used was a 350 but i amy be wrong and he could of said 305. Sorry but i am not familar with the GM terms. Long story short he said he would cut me a deal and sell me the motor for 800 bucks. Catch is it come with a auto tranny. It's still in his car and the motor has 91, 000 kms on it. He has the papers and car to prove it. He said i can even drive the car if i want to test the motor. He also told me i can mate the 6 speed tranny to it, t265 i think was the code he said.

Now i know any of the motors i mentioned above would take some serious work and an experienced mechanic to do. Is this a good deal? is the 350 a compariable motor to the LS1? Another buddy that was with us also said that i sould run the carbs for it instead of it being fuel injected. Now remember i am getting the whole motor, ecu and tranny for 800 bucks. What type of numbers does this motor produce? is it worth the hassle? Help me out guys....i will do some research my self just thought i would ask some of the e30 gurus here. Now i know this is a chevy motor going into a BMW so please don't post any negatvie comments. I am just looking for some constructive and helping advice. I figure jay and Zimmie and BMWBMXER should have some good info for me. Thanks guys

dude, the LT/LS are world difference, the LT are iron block where LS are all aluminium. The weight difference is huge, an LS1 crate engine weights 390lbs out of crate. Not too sure about LT.

honestly, if you have the budget for LS engine, don't even bother look into the iron block, an LS1 is like 360hp minimum, LS7 starts at 505hp.

I believe the motor makes like 200 something odd horsepower, a Camry v6 (not the new one), can trump that thing.

if its a 1991 automatic Trans Am its either a 305 lb9 - 200 hp or an 350 l98 - 240 hp. If its a firebird I think those also had a low level TBI 305 which put out way less than the 305 TPI's 200 hp.

The cost of the motor will be a small percentage of the total project cost if you're not doing most of the work yourself. I would wait at least for an LT1.

As Nick so politely put it (and I'll translate what he's really saying), that motor is absolute crap.

Call Rocco, I'm pretty sure he's sourcing the motors too. LS1 and up if you're going to bother.

Ya there are tons of 350s/305s. However the firebird ones generally are not the greatest.

If you were putting it into another chevy (ie blazer, which as a side note I am infact saving for.) I would say go for it as it is pretty simple, but for the amount of work it will take to put into an e30 I would also wait for an LS1.

I am glad to see that you do not want to go BMW v8.

Here is a page of an e30 with a small block 350 swap: http://www.personal.kent.edu/~wbainey/BMW.htm

It seems pretty old but maybe you can get a hold of one of them.

Good luck.

^^ what Jay said

the final price of the full conversion after everything said and done will be $10K+, reinforcing everything so the car wouldn't fall apart under 400hp will be another at least $6K
No reason to cheap out on the motor.
If you are going - go all the way, otherwise money is wasted IMO.

Also i would not advise making decisions on what your buddies say.
Your best bet is to find a specialist who has done these swaps and knows what he's talking about.
