No clue but Smittro will know. He should be in here within the hour

[zboy2012]

ok thanks

Did'nt I answer this already in another of your threads?

Yes you can make it fit.. It's been done before..

But for the work you'd be better off to build a 60*v6 instead and not have to change the trany inless you have the 4cyl grand am..

But be warned the 4t60e and the 4t65e(HD) is a junk unit no matter what engine is bolted to it..

It's well known that 60*v6 can be made to make better power N/A and are lighter than the stock l67..

You're looking @ barely 240hp in the l67 (depending on year) with about the same amount of custom work on an LQ1 N/A you're almost there already @ 215~225 stock.

Build a set of headers and a custom CAI and there's no need for the heavy l67.. Especially in the lighter J-body cars..

ya ik but i like the supercharger wine and what tranny would you recommend?

[Smittro]

A muncie 5spd, or the 4t80e if going auto..

You can build the other two I mentioned to handle more wear and tear but they are still not the greatest units..

o then what would these two herr u just listed be good for? and i'm goin to go auto

The muncie will handle ~400+hp crank. Kryo or heat treatment (depending on HP goals) to it's internals will make it handle even more..

The 4t80e (large unit) will handle just about anything (within reason) you throw @ it.. Say safely also ~400+hp crank..

The 4t80e came in FWD Cadillac northstar v8 models, and in the last Oldsmobile FWD v8 Aurora's.. Pretty sure the v8 GPX uses it as well.

It's a heavy duty unit with heavy duty weight too..

Many folks use a built 4t65eHD with success.

But it's hit or miss finding a solid used unit to start with unless you buy a new one and build it..

The main problem is the differential area is weak and has been known to flex under stress..

Adding an LSD can help a lot but may not cure the issue..

With all this said, many folks also have had the weaker units last pretty good under normal situations..

However if you ever get it stuck or race it often it will be toast or will start the die in a relatively short time...

so i can build a 4t65eHD and wwill do jsut fine?

If you're not racing it on a regular basis yes.. But as stated they are'nt the most reliable units..

4T60-E
Main article: Turbo-Hydramatic 125
The 4T60 was the transitional model from the old Hydramatic (formerly called the 440-T4 aka 4T60) to the new electronically-controlled transverse family. Introduced in 1984 on the 1985 C-bodies, it was enhanced with electronic controls to become the 4T60-E in 1991. By the mid-1990s, the 4T60-E was the transmission of choice in nearly every front-wheel drive GM vehicle with the exception of compacts. A heavy-duty 4T60-E HD was produced only in 1996 for the supercharged GM 3800 engine. The 4T60-E was phased out in favor of the 4T65 beginning in 1997.

The 4T60-E featured a 245mm torque converter with varying stall speed and gear ratios. Stall speed is the rpm(revolutions per minute) that the converter reaches maximum efficiency and is correlated with the engine and vehicle weight for the best combination of power and efficiency for the vehicle. (For example a '95 Beretta features a 1650rpm stall converter as opposed to '99 Century converter with a stall of 2095rpm.) Gear ratios are remarkable in the 4T60 family in that there are two points in which the transmission can have different gearing (the drive-chain sprockets and the differential, or Final Drive) resulting in up to 12 different available gear ratios. The combined gearing of the two is called the Overall Axle Ratio, and the different ratios allow the use of the transmission in multiple applications based on the engine and vehicle. Please note then that there are up to 12 different versions of the 4T60-E, and they should not be mixed as undesired operation would occur.

Gear ratios:

1 2 3 4 R
2.92 1.56 1.00 0.70 2.38

[edit] 4T65-E
The 4T65-E was introduced to replace the 4T60-E in 1997. The 4T65-E included a larger 258 mm torque converter for some models and many other changes to improve reliability. It is able to handle vehicles up to 6500 lb (2948 kg) GVWR with up to 280 ft·lbf (380 N·m) of torque. A number of final drive ratios are available, with many distinct models. Starting in mid year 2000 models, all 4T65-E models received an upgraded valve body. Starting in 2003 the internal electronics were changed, hardened 4th gear shaft, ratcheting sprags for input and 3rd gear were added.

Models:

M15 — 245 mm (9.6 in) torque converter
MN3 — 258 mm (10.2 in) torque converter
MN7 — 258 mm (10.2 in) torque converter and heavy-duty gearbox (see 4T65E-HD)
MD7 — 245 mm (9.6 in) torque converter (Chinese version)
M76 — 245 mm (9.6 in) torque converter (with all-wheel drive capability)

do u know if intense parts are any good?

[Smittro]

do u know if intense parts are any good?

They have a 3800 in the 8's..

[zboy2012]

They have a 3800 in the 8's..

it's gonna be a DD so u think heads and cam would be good for that

[Smittro]

You'll need more than heads and a cam to ever see 8's with a 3800..

[zboy2012]

o i dont wanna c 8's haha i just want something that'll run at least 12's-11's
