Hey guys, New to the site and need some help.

Do you guys remember that cp racing had a bolt in rack and pinion conversion for the 1st gen.

Does anyone know of anybody who is still makeing that setup or has one willing to sell.

I just finihed putting a 13bt-rew into my gsl-se and the thing is a little difficult to controll on the street and even more scary with the vague 1st gen steering setup.....

Another REW, great. Got any pictures?



CP racing did sell one but as you know they are long gone now. And for good reasonI hear. As I recall it was a VW R&P correct?



There are a couple other options that you have:



1. 2nd gen subframe. This would give you the R&P but you have would need to re-fab all your motor mounts.

2. Custom fab up a bracket to hold a R&P. Personally i do not advise this. There is a lot more to a steering system tham people realize. I learned this the hard way with a buggy that I built. Then again it had over 12" or suspension travel.



Personally I would just upgrade your stock suspension. There are tons of cool little add-ons that you can do. Ie. Stiffer springs better struts, Cabmer plates, turn-in spacers etc. I rode in a very tight rx7. I was surprised how well it handled compared to mine. Suspension is under rated.



Good luck.

The second gen subframe is a pretty easy conversion to do, I have done one in mine with the Rew as well, have not had a chance to drive it yet. Still building it.



Heres some pics.

I used the front bolt for the factory subframe, which in turn put me about an inch to far forward in the wheel well, But the caster is awsome, the car turns so smooth sitting still, and rolling at pushing speeds. I built all my own exhaust and turbo Manifold, the wastegates route back into a single 2 1/4" and meets up with the down pide where it goes to 4" up and over the axle and out

Thanks for the little insight guys. I have tons of flicks but Its on kodak i'll have to scan them, I spent all the money in the car so I couldnt afford a digital camera https://www.nopistons.com/forums/pub...>/rolleyes.gif . ( a 150.00 camera WTF https://www.nopistons.com/forums/pub...DIR A 6000.00 engine, OOOOhh yeah)

The engine was built in pureto rico by Vivo ( the guy who ownes bam bam and who beat rafelito before,stilll has the article framed in his office.

The sub frame sounds like a next fab job that I will have to ponder a little longer. My mind right now is dealing with the weak rear end. I just spoke to grant at grannys to do a 8.8 for the car.

I have raced a two turbo hondas and when I pull for 2nd I just walk away so easy that I just granny shift 3rd and back off the throttle and thats on 93 pump gas with a weak rear. Now no honda wants to race. On to the pony cars (well after I get my rear end)

Why not get a Kaaz?

z-beater 07-11-2007 09:55 AM

Do they have a Kaaz for a 1st gen? I have never heard about this. Here is what I would do.



1. Brace the housing so that is cannot twist

2. Install Respeeds moser axles

3. If there is a Kaaz get that as well.



I don't know why people jump on the 8.8" so quickly. The reason I have a 7 is to have a light car. Why would you want to throw an extra 80-100lbs in it. I am trying to get weight off not put weight on.

gsl-rew 07-11-2007 02:29 PM

Everything is a trade off? More power means I need stronger axles more axles means more weight( more or less) I would love to keep the stock rear end But The stock rear has its limits. Its really only good up to about 250 hp even with the kaaz or torsen unit installed. I'm getting 420 rwhp on pump gas. and I want to run slicks on the track.



You see all axles flex. ALL.Even the axles in the big semi trucks with 55000lb rated axles that are thicker than your arm. the spline area is suppose to be the thickest part of the axle with the rest of the axle taperd down, this lets the load of the launch to be spread out along the complete axle. I saw an upgraded axle for the stock gsl rear on the turbo fb (yahoo) site with this axle being big and beefy BUT tapering down TO the splines. With this setup with lots of traction and power the load can not be transmitted along the entire axle and it will snap right after the splines all the time. Evertime.



So in a nut shell the axles coming out of the carrier is to small for the power.

But if someone knows of a way to stuff a bigger carrier into the stock rear let me know.





OOOOOhhhhh yeah arnt you guys suppose to be helping me with my steering https://www.nopistons.com/forums/pub...R#>/tongue.gif

Anybody with a cp bracket who wants to sell.

gsl-rew 07-11-2007 02:43 PM

Oh and with the rear from grannys Im getting it with the turbo II bolt pattern and the tII caliper bracket so Ill just buy the big brake upgrade kit for the front from re-speed and I'll have 5 lug all around.



Now tell me that nice.





And its a daily driver

z-beater 07-11-2007 03:22 PM

Ok, to each there own. I don't drag though with huge slicks out the back. Guess it depends what you are doing with the car. Weight savings is the name of my game.



Just trying to offer some other options. Seems like most people around here are lemmings following the leader.
