Re: Performance parts ! (marlon88)
What you gain 1/8mi with the 3.54s, youll lose in the next 1/8mi.
You have 2.59 as the stock ratio, 3.07 would be the perfect gear for the L98, but with the D44 casing if hes offering a good price AND youre planning on engine mods later, then i might buy that. You will need the D44 for the slicks, the D36 will shred itself to pieces. The slicks would be your best gain in ET.
Performance throttle thing is junk, so is the hypertech chip

Re: Performance parts ! (marlon88)
marlon, i think you missed vader's point. he was saying the 3:07s would be optimum on your car as it is.
the 3:54s are gonna wind to quickly for an l98, but may be ok for you later on if you affect the upper band with your mods or motor swap. as far as your tranny goes, it's a good unit as is, but if you want to beat on it a bit (like we all do) you may want to beef it up. the more you hook, the more stress you're putting on every part of your driveline.
the D44 will absolutely be a lot more stout, so in effect, all you're doing is transferring stress to the other parts of the driveline (u joints, half shafts, driveshaft, tranny). the key is first going after the easiest thing to break, which is the rear end (which you're doing), especially considering the use of slicks. if you're gonna stay low end (l98) then your best bet would be 3:07s in that D44.
geeze, hope i didn't confuse the issue :lol:

Bottom Line, 3.07 is the perfect gear for your car as it is.
If youre going to do engine mods, then it would be OK to go to 3.54s.
If youre going with a SuperRam one day, the 3.07s will still be perfect for it.
If youre going with a Miniram one day, the 3.54s might be better for it.
Either way, a D44 carrier is a good idea, your tranny can handle the 3.07s or 3.54s, whichever you choose. However, if you put 3.07s in the D36 you have now, and also put drag slicks on the rear, youll blow the differential to pieces. The tranny can handle the drag slicks too, the stress is more on the differential/u-joints/halfshafts than on the tranny. So you must put a D44 on if youre going to go with drags one day, you dont have to beef up the transmission.

Re: Performance parts ! (marlon88)
Can some one say if the 44's torque beam can go onto his tranny? Or can his beam go onto the proposed 44? I'm :confused: not sure 'bout that.

Re: Performance parts ! (89 Paul in Cal)
I'll know for sure in a couple weeks when I put my D44 in Paul. I have the torque beam from the new one plus the one that's still on my car. Previous posts say the new one works perfectly, but you can also use the D36 torque beam by just re-drilling it because the D44 is aout an inch or so longer. Same issue with the driveshaft too they say. Keep in mind this is just from what I've read, not personal experience (yet :D )

Re: Performance parts ! (Caboboy)
If the slicks are taller than your normal street tires, the 3.54 may work well at the track. With normal height tires, you may not like it driving around normally though. I have read 3.73's are too far for stock TPI cars, and 3.54 is about as tall as you want to go.
