Got this LT1 that spun a bearing from over revving, he had this motor in his RX7 then rebuilt it. It was bored over .30 and ported and polished. New pistons, new crank, but we think it's the same rods. Since I don't have the tools needed to do the swap, a friend of mine is doing the swap. I was told today one of the pistons were backwards... This kid that sold me the motor is suppose to be an experienced mechanic. When I say kid I mean 20-21 years old. He says he's rebuilt plenty of motors before and he seemed legit at the time. Other problem my friend says is it's extremely hard to turn the motor over. It's suppose to be tough, but not that tough. I'm not much for the internals of motors, but is this motor worth trying to put in after fixing these problems or should I find this guy and get my money back? But it was for a pretty damn good price, I would like to put the motor in if it's at all possible. I'm willing to bet it's not going to be as easy as getting my money back and giving his motor back. I'm not going to call him either about the problems with the motor, were going to take it by a machine shop and get opinions from someone there too. I'll call him up one day with the list of problems when I'm ready if it comes down to it.

my lt1 was sometimes stubborn on cold starts.

good luck on the swap though

How is the piston backwards??

Intake valve reliefs,exhaust valve reliefs.If lt1 is a rotary then disreguard my stupidity

No you are right. The LT1 is what you are thinking it is.


I would just make sure when the motor is taken apart on your own accord that its properly put together. I wouldn't worry about it after that though. However, I would look over all the wiring the guy did on the car. I am going to assume it is a FC. So just double check all the nuts and bolts on the whole vehicle to make sure there is nothing else done poorly.

The whole vehicle??? I'm putting this motor in my 93 Z28. It came from his RX7 which he modded for it to fit in. He over revved it, spun a bearing, rebuilt it, it was then sold to me. I also spun a bearing but I don't know the extent of the damage so I'm just replacing the motor all together with this newly rebuilt one. I'm having the problems as stated. I don't know if it's normal for it to be that hard to turn over (manually turning over with wrench), or what else he could have fucked up if he put the piston in backwards. We received the motor in several pieces so we are able to see what's going on.

Oh ok. I was making the assumption it was going back into the 7. Thats why I was saying to double check everything he did. But if its your vehicle then don't worry about it.

It's a piece of shit. I went to check it out today, it turns over about 3/4 of the way and gets stuck and you have to muscle it to turn it the rest of the way over. The piston is like, upside down... and there's a label on it that's suppose to match the others. I don't know how you fuck that up. One of the rods that connect to the crank are slightly loose whereas the rest of them won't budge. It's like somethings bent in the motor, it just doesn't flow 1/4 of the way.

What was he asking for it?
