TGP/Beretta


Beretta

Recommended Posts

Hello i have searched this already to no avail. why wont a 3.1 5 speed from the beretta or the 2.3 5 speed work with the TGP 3.1. I dont really understand why the input shaft would be a problem. is there something u could swap from one engine to the other ?

the 2.3 has a completely different bellhousing bolt pattern and wont even bolt up. if you get a 282 from a 5 speed v6 beretta then you still need to find a W body donor for the rest of the swap parts.

The Getrag 282 is quite strong.....it has stood up to quite a few L67s in both FWD platforms and Feiros.

 

He was refering to the 2.3L Quad 4 5 speed (a Getrag 282)............not the manual transmission used with the ol' Iron Duke.

 

Now, it is quite possible that you could use the Q4 manual (I don't know why you want to, the V6 Getrag 282 has gearing suited for a 3.1T and is stronger).........2.4L TC are basically a Quad 4....they where also bolted to 4T60 transmissions in J bodies dueing the mid-90s.....so was the 60 degree line up. So, it is possible they have the same bell housing bolt pattern......I have never compared them directly. The Getrag 282 is a flat out better choice.

the ultra rare W-41 quad 4 transmisson would be awesome...i know where one is too...3.94:1 gears and posi traction WHOOHOO....but then again i don't have a car or the time to try to put it in

i thought i was told the tranny from the quad had gearing that was better suited for a turbo charged engine. oh well i have the 5 speed from a 3.1 beretta so what other parts will i need i have a tgp engine; turbo; intercooler and tubing. as some of you have read im just looking for a turbo. is there anything else i am going to need ? and what am i going to do about the early 90's mount getting in the way ?

 

Also why would the tranny from the quad be weaker ? The quad has more h.p. than the 3.1 and the same amount of torque. albeit at a higher rpm.

 

 

 

Thanks Guys

the LO Quad-4 and other 4 cylinders did not use the Getrag 282; they used the weak Isuzu 282.

 

as far as 4 cylinders go only the HO Quad-4 and Turbo 2.0 engine used the Getrag 282 as far as i know, yet they still don't have a V6 bellhousing (the bellhousing CAN be swapped)

 

does the Getrag 282 from a W-41 car really have limited slip? i have my doubts...

 

a 5-speed from a HO Quad-4 will work, but you'll need to replace the bellhousing with one from a V6 Getrag 282 because the bellhousing bolt pattern is different. a Getrag 282 from a 2.8/3.1 Beretta should work just fine with a TGP engine.

not if he's putting it into a Beretta :) you'll probably need the L-body specific intermediate shaft and both axles.

i don't see how the input shaft could be a problem at all. do you mean the intermediate shaft?

Quad 4's (HO's anyway) got a total of 4 different gearsets for 89-94.

 

89:

 

1st 3.50

2nd 2.19

3rd 1.38

4th 1.03

5th 0.72

Axle 3.61

 

90:

 

1st 3.50

2nd 2.19

3rd 1.38

4th 1.03

5th 0.81 (shorter 5th gear for stronger top end accel)

Axle 3.61

 

91:

 

1st 3.77 (shorter 1st for launch)

2nd 2.19

3rd 1.38

4th 1.03

5th 0.81

Axle 3.61

 

(These BTW, are the same as all of the W Body 282 V6's)

 

92-94:

 

1st 3.50

2nd 2.05 (revamped 2-3 gear spacing to help the horrible rpm drop for that shift)

3rd 1.38

4th 1.03

5th 0.72 (back to the long 5th.......it's actually close to the same with the 3.94 axle ratio)

Axle 3.94

 

(These are the same as SCX gears except for having a longer 5th).

 

Everything else Brian's page is correct.

 

I don't view the W41 SCX transmission as that great.......sure, 3.94 gears would be cool.....but thats to deep for the low end of these V6 motors.......and the limited slip it uses is cool too, but really isn't that great....its only a viscous unit afterall.

if i had a choice of Getrag 282 i would pick the '89 HO Q4 gearset. i hate the 3.77 1st gear of mine....way too steep IMO (really good for burnouts). i'd probably save gas with the 28% overdriven 5th too. right now in 5th gear @ 75mph my RPM is about 2700. not that bad but 5th gear is a highway cruise only gear for me....i could care less about 5th gear acceleration.

and what am i going to do about the early 90's mount getting in the way ?

 

Thanks Guys

you'll probably need to build a custom crossover because the TGP crossover is not going to fit in there with the L-body transmission mount right there in the way. and heck, if you have to build a custom crossover i would forget about the TGP T-25 turbo altogether and build a crossover with a T3 flange instead.

im pulling up a mental image of my engine and i dont remember a mount located where the crossover lives. ill have to go look at it today.

i think it depends on the year (it's been a long time since i owned my 5-speed Corsica). i think the earlier L-bodies have the mount in the way and the later ones don't. or something like that.
