I was looking into swaping out my rearend in my 89 auto vert hopping to get some better accel. but i dont know where to find any parts like that, can any one help me on this?

thanks

 

The GTU's ran a 4.30. If you can find one, that will fit.

 

Any NA will fit. Is your question what you should get to make it work, or where to get it?

 

The GTUs had a 4.3, the GTU had, I believe, the 4.1.

IIRC, any S5 N/A LSD will drop right in.

 

Any rearend from a NA Stickshift 2nd gen will work. Just make sure to get the speedo gear also

 

What to got.

Im not really looking for stock fast, im more looking for my god fast. I sont care how fast it will go, 110 is fine with me, i just want it to get there FAST.

 

get a 5speed rear gear. it is 4.1. That is the cheapest way to do it. Mazdatrix sells the 4.3 rear gear BTW, but it isnt cheap. Niether is one is oh my god fast, autos steal too much hp IMO. Plus you got the slowest/heavest 2nd gen made! To go "oh my god fast" with an auto vert, save up for a LS1.

 

thanks.

Yes she is big and heavy but i still love her, thats one reason why i like making her better, so the slowes and heaviest will be faster. I plan on dropping a turbo block in here in the nxt few years.

 

I just put the 4.1 in and it was pretty much a bitch and requires alot of man handling everything, especially if you got rust.

 

A t2 swap will get you the speed your lookinh for, BTW clean as car, looks great!

 

Thanks

about the swap, i have found a car with the block( i havent actually seen it) but what the guy says it sounds like a s4 would that have a better rear end also.

 

S4 LSD is clutch, hence why many prefer it.
