Custom chassis car
Thursday, December 28, 2006 7:45 PM
Anyone ever see a second gen j body hung on a RWD chassis other than a jbody thrown onto a short S10 chassis. I've seen a couple of RWD conversions, but never actually a car built to have the body work and some interior stuff hung onto it. I've been kickin around the idea for awhile but never really seen an example of it. I'd like to build a car with a Z24 body, using some dash and interior pieces aswell. Figured it be something different.
Right now I'm pretty set on using the last generation f-body runing gear with a northstar.
I have a enough know-how to build a chassis myself from the ground it's just gonna be a couple years before I have the time for a project like that again.

yea ive seen it done. there are lots of j-body drag cars. they are built with a tube chassis and then a fiberglass body, and a glass dash modled after a stock one. you could do the same thing with a steel body. just get a shell that is straight, cut the body around the rocker sills and set it on a tube chassis. you would have to build a floor to fit, but the dash and most of the interior could be stock stuff.

ive thought about doing it, but it realy doesnt interest me enough to do it. if i wanted a rwd car it would be something with the main goal to be fast and handle well. id start with something like an old mg, datsun 510 or 280z, or a kit car of some sort. i realy want to build a turbo 3.4l twin dual cam twin turbo. these motors have a lot of potential but most people dont build them to there max because they are only in fwd cars and the drivetrain reaches its limits very quickly. id love one in a rwd with a 5 speed.

Yeah I seen the drag cars built like that, but I'd like to do something that apeared like a production z24. I'm looking at just using the sheet metal skin of a car, not setting the whole unibody onto a rolling chassis or getting a stretched fiberglass one. I figured it would be a project that would take some time and be a platform I could really build up to some performance. The wolf in sheeps clothing.
I was going to keep my 90 z24 and convert it into a RWD car but I figured I could ultimitaley get better performance if I spent the extra effort in fabricating a frame to hang that body on. I just never seen one done to be a street car that didn't look like a hacked up unibody underneath.

you can build a rwd out of a j-body without building a rolling chassis and still make it nice. many muscle cars use unibody construction, and you can utilize it like they do. you could get a rear clip with the 4 link for under $1000 from art morrison. you can cut the floor out and weld that into the body much like it would be done on something like a nova or chevy II. as for front suspention, you can use 3rd gen knuckles installed on the opposite side they were ment to. this allows you to use a steering rack ahead of the motor. this allows you to use our complete stock suspention, you just need to install the outer axle end to keep the wheelbearing together. you would need to cut the firewall and a tranny tunnel, and thats the couple things that would prevent you from using the stock console and heater system. you can weld the mounts right to the subframes. i would install subframe connectors to strengthen up the body.

it is fully feasable to build a rwd withou using a chassis. it has been done many times with stock eliminator conversion cars (a fwd car converted to rwd with a v8, designated GT/-- ). there actualy was a front end kit for the beretta that was a bunch of stock parts moddified for rwd with smallblock mounts, a firewall templet and a tranny tunnel already cut out. all you had to do yourself was the rear suspention.

I have seen an 84 or 85 Sunbird on an early '80s G body (Monte Carlo, etc) frame. The frame was shortened but not narrowed. All of the original suspension and axles were used. 4WD S10 wheels were used due to the offset. It wasn't a bad fit. The frame rails hung out a bit but looked OK. I've also seen full on custom chassis and a few FWD cars with RWD axles and suspensions hung on 'em.
