will a 7 bolt swap in a 1g

[superpimp]

theres tons of post on 6 bolts in 2g cars but no 7 bolts in 1g cars is it do able???? heres what I have a 99 gst low miles (rolled) and a 90 gsx with a bad motor. that is why i want to do this swap. I know 1g is stronger blaa blaa blaa. WHAT DO I NEED IF DO ABLE?????

youll need a 7 bolt gsx flywheel thats for sure .

Wow, I'm not sure if anyone has even attempted this swap. You might have a tough time finding information on what's needed. You're running toward the crankwalk storm while everyone else is running away from it.

With that said, I'm sure it's possible. You'd need a number of parts. I couldn't tell you exactly what is needed and I'm not sure I'd tell you if I did know. I'd feel guilty for helping you do something you shouldn't be doing.

Actually, you arent helping him do anything. It is almost impossible without tons of fab work.

First off, 1g's(mid 92-94) did come with a 7 bolt, but the block design is totally different from the 2g 7 bolt. The reason you never hear of anyone doing a 2g 7 bolt into a 1g is because there are no engine mount locations on the front or rear of the 2g block for use with the 1g engine mounts. If you take a close look at both of your cars, you will see that the 1g has a mount bolted to the block under both the turbo and intake manifold. Now, if you look at the 2g, these mounts are located on the transmission, not the engine. Look closer and you will find that there are no provisions on the 2g block for the 1g mounts to bolt to. In order for it to work, you would have to use both the 2g engine and transmission and then do some custom fabrication so you would have a location for the 2g mounts to bolt into the 1g chassis. On the opposite swap(6 bolt in a 2g) the 2 g tranny is used which retains the factory mounting locations on the tranny, so in turn, the mounts on the 6 bolt block are not used. After it is all said and done, it would be a waste of time and money to install the weaker 2g counterpart into the 1g chassis.

Now Chris you know that since its a 7-bolt doesn't mean its going to CW. Anything with a piston can CW. The 99 7-bolts have virtually no records of CW's, 98s have very few, so he would be pretty well off if he went with one of those. I would imagine that a 7-bolt would fit in a 1G due to the fact that 7-bolts were in late 92s-94. I think the 2G motor mounts are in different spots then 1G MMs, so you would have to fortify the block and custom weld in 2G MMs if the motor is out of a 95+ . I figure if you find a thread for a 6-bolt into a 2G, you will need those things but for a 7-bolt swap from a 2G 7-bolt into a 1G. If your using a 7-bolt out of a 1G it will drop right in for sure. You will need a fly wheel for sure though.

Man I would think it is possible. I say if you dont have alot of money and that is why you are doing this then go for it. I dont see any real reasons it wouldnt work and you should have pretty much every thing because you already have the motor an tranny. And come on crank walk is over rated how many times do you really here of this. Its not like the seven bolt is a bad motor. I say go for it you shouldnt need to many more parts you already have two complete cars.

beat me to it. I agree With him.

Good luck,

I didn't say it would crankwalk, I just said that everyone is doing 6-bolt swaps into 2G's (usually to avoid crankwalk) and it's almost unheard of to read about a 7-bolt going into a 1G. He might have a tough time finding someone who has done the swap that will know exactly what is needed, from first hand experience.

'92awddsm nailed it on the head. You will need to accomodate for either the motor mounts to be fabricated to the block, OR as said, would need to swap the whole tranny/motor and fabricate the mounting positions to work with the 2g mounting locations. Has nothing to do with crankwalk or not, just the fact that if he is doing it to "save" money, it would be a horrible way to go as you will dump more into fabricating than anything.

Thank You Thats Correct Not Alot Of Money To Play With, The Mm Sounds Like It Would Be A Problem. The 2g Tranny A Have Is Fwd, Car Is Awd To Buy A Tranny & Tcase Then Make Mounts Is Not Cost Effecitive For Me. Time To Save Money For 2.3 Stroker. Will 2g Cams & Or Gears Work On 1g? Thanks Agian

1g cams are a little more aggresive so there is no point in switching them around.
