My car currently is using a stock '86 951 tranny. Stronger, and the gear ratios are slightly more in tune with a converted car. I think a late 968 6-speed might be a nice addition, but have heard they are not a strong as the 951's 5-speed. My car runs 80 mph at 2700 rpm. I would like to reduce that to around 2200 for crusin', but if we can't engineer the 'Vette transaxle, then a higher 5th gear from POWERHAUS

totally cool! couple questions:

1) how much heavier is the LT1/4? does is affect handling much?

2) got any pics of the engine bay?

My understanding is that the answer for #1 is just like 50-100lbs. Seems kinda low to me, but I guess the LT1 is all aluminum, so maybe. I'm sure someone else has a more accurate answer to this. Heck, if it's only 50lbs, how much of that is made up in loosing the power brakes, lol.

Either way, I'm pretty sure it would only take the car to about a 51/49 ratio (remember stock is actually more like 49/51 on N/A's). Might even be able to 'cancel' it out by using all fiberglass front body panels (hood, front end, fenders, etc.). I think if combined with a good suspension setup & turbo transmission it could be a good setup.

It's just those power brakes that bother me. Is there any way to do power brakes without the big thing in the engine bay (why can't I think of the technical term)?

93 is the only year with the viper transmission and no first to fourth lockout from the factory.

I posted a link to a gear/speed calculator a few weeks ago.

with the stock wheel size 26.66 height (275/40/17 or 245/60?/16) im running 2700rpm at 80 in 5th and 2100 rpm at 80 in 6th according to the calculator program. I guess the final drive of your 5 is about the same as GMs 6. at 80 with the stock motor in 6th i am at the sweet spot of the torque curve, with your mods are you going to have to downshift to get to the sweet spot if you change gears, and if so will fourth be to tall leaving a dead spot in the gears when the motor is in the sweet spot?

I don't think its a Viper transmisson. All the 6 speeds were Borg Warner. 93's just had a different first gear ratio.

Correct me if i'm wrong, but i'm pretty sure its not a viper tranny. Weren't those Tremec 6speeds?

Here's a way to move some front end weight rearward - Relocate the battery to the left rear fender cavity below the carpeting. Just like the 928. Just ground it to the frame and run a cable to the starter.

That will move about 50 lbs to the *** end where it belongs!

Scootin159

Not a bad idea. RHD cars already have it there, so you could even use some RHD parts to make the job even easier.

Tom R.

here is a link to a thread on the mullet board that explains it all. it also has a link to a site with the max torque figures.

i was very surprised to learn the car had a viper transmission too.

"In 93, when GM started the LT1 F-Body production, Borg Warner didn't have the F-Body spec T-56's ready yet. So GM goes to Chrysler, and buys up a bunch of Viper T-56's. Thus, the two different ones in the 93 F-Body, and the different gearing and power rating. The M28 was the weaker one."

Scootin159 - are you saying RHD = right hand drive? And if so, did all 944's with RHD come with rear mounted batteries?

Does anyone have any PIX?

Tom R.

yeah, and in the later models, if the battery runs down you cant open the hatch to get to it. run a search about six months ago.

Scootin159

haha, yeah, forgot about that. Just curious, anyone know why they 'upgraded' it? Does it actually work any better? I guess your best option is probably to just install some jumper posts up in the front under the hood for such a problem.

Gotta be worse on the cabs as you can't even climb over the back seats.

My car gained approx 120 lbs. 80 in the front, 40 in the rear. No effect on handling that I can detect. Some LT-1's came with iron heads, most with aluminum. Most desirable engine is '94-'96 Camero Z-28 or TransAm, because of the serpentine belt set-up. All my pics are too big to down load to the post, but you can see 'Predator' on the Renegade site. Look in customer cars, (I'm Scott in Brentwood), and fun stuff (Hot Rod Power Tour). Also p-caronline, (Scott in Tennessee).

e-mail me the pics in full resolution & I'll get them hosted for ya. I'm sure everyone here wants to see them & I'd prefer to see the full-size ones if possible.

Tom R.

i thought the 93-97 motor was the same except for the venting of the optispark. 97 camaros had the new interior with the old lt-1 mechanicals LS-1 was from 98 on.

trivia i would not have known or desired to know until three months ago.

Er no, not all RHD cars have the battery in the boot, there are actually a few different bulkhead's to these cars, i guess the early 944's used the 924 set up so the battery was under the bonnet, the European cars had the battery in the boot but they were also LHD, my race car is LHD and abd the battery I moved to the boot, this gave me somewhere to put the remote brake servo. One thing to note the two with the battery in the front both had no sunroof, I wonder if the bulkhead on these cas are slightly different.
