All Series II L67s were rated at 240hp. They were made 1996-2004. Early L67s(96) came with the 4T60E, later ones(97+) all came with the 4T65E-HD. The 4T65E came with NA 3800s 97/98 and newer.

Not all of the PCMs are interchangable. Generally 97s and 98s are on there own and 99-2002 are very similar. Your best off getting the PCM with the engine and tranny. This is the only way to be absolutely sure that it will work.

i bought the tranny from the 99 regal. the junk yard still have the font clip from a 99 GTP complete, and a motor with wiriing and pcm. i will be going back tuesday to remove the wiring and PCm from the regal. you can give them a call 718-381-2727. they are located in 4600 metropolitan ave, ridgewood n.y. 11385

yes all 97 and up regal ,GTP,Bonnevill, and park ave came with the aluminum spinder. i think on the 97-2003 bonneville came with the aluminum craddle. i know the 2004 s/c motor is a series III with a littil re-de-design on the m90 s/c the 2004 series III motor push 260hp and 280ft-tq. yes you can wire the 2004 setup into the t-type, but you must you the old casting of the 4t65e, manily 97 and 98. all the component from the 99-2004 with fit into the 97-98. the is not much differance in the unit.

hey thanks t and stevex,, t you mentioned 97/98 is stand alone and 99 up similar, what is the diffrence thou ? steve, if i were going to do a 2004 setup why must one use theold casting of 4t65e ? has anyone made the ac work ? wich compressor was used ? can the newer compressor be used with the rest of the t type ac system ? if so what gas was used and is it still cold ? steve x you most likey have no need for cruise control while racing, so t have you hooked up yours ? if there were to be a lets say 98 parkave non sc 3800 and a 98 parkave sc 3800 next to each other are the wire harness still the same? if not what is diffrent ? stevex i was under the imppression the term front clip meant when they sawzaw the car in half, from the dash to the front bumper is what you buy, i thought. i called up the junkyard you mentioned and they want 2500 for engine/ trans/computer/ and wiring , is that what you meant by front clip ? why would they want more over the regal ? sorry for all these questions but id appreciate it if any one can answer them . thanks

I believe the 99 and newer trans is missing a few of the bolt holes that
we need to mount the trans in our cars. The older models have holes that
match up with the existing mounts.

I used the T-type ac compressor. Just needed to modify the mounting
bracket to move the pulley out of the way of the supercharger belt.
I stayed with the r-12 system since it was all working and in good
shape before I did the swap.

Just to be clear, the 97 PCM is different and has different wiring. The 98 and
newer pcms are all the same. They both work equally as well though.
Make sure you get the pcm to match the wiring. I basically followed
the wiring diagrams for a Grand Prix GTP so I could use the grand prix
aftermarket pcms.

All of the parts I used came from a 1998 riviera (excpet the half shafts
from a bonneville)

the 3800 n/a and the 3800 s/c wiring and pcm are different. they are not interchangable. i am pretty sure if you are buying the front clip. and you are standing in front of the junk guy with $1600-$1800. he will sell you the front clip. i use the method all the time. people react differently when they see money in front there eyes. i don`t not have a/c on my car at the present time, but i do plan on installing the a/c later. has for cruse control. i don`t think i will ever need it, i love being control of my car, and you will too if you where driving it.

you need the use the 97-98 casting for the 4t65e. GM change the casting form 99-04, but the interinal are the same. the 3800 n/a and the 3800 s/c are two different tranny when it come`s HP. the s/c tranny has more roller bearing ,where the 3800 n/a has bronze bushing/guild.

yes, the front clip is the car cut from the wind sheild piller. the regal you are talking about has 38,000 mile ,i think.

when you car ready to buy , it is alway good the have the cash in your hands, while you car talking to the junk guy. money will change the personallity of a person right away.

i do not want to use a CC because you will have to pay full price PLUS you will have to pay sale`s TAX. the difference between the 3800 n/a and the s/c it the program perameter. and the wiring goes to different pin in the pcm, plus the s/c motor have sensor the n/a motor don`t have.

I think it would be a good idea. I'll give everyone a chance to know it's moving.
