ragejg Posted June 18, 2005 Report Share Posted June 18, 2005 I was gonna swap my 91 buick 3.1 motor in to replace the SHOT hunk of metal under the hood, but it looks like that motor may stay in my 92 euro for a while... So if this happens I can wait a while longer and swap something else in. I have the oppurtunity to obtain a 92 Delta 88 with a severe tranny problem, for $200... the car has 207k but I do believe the 3.8 is it's second motor... For a 93 3.1 to 91 3.1 swap, I've been quoted a loose $1200 @ my local shop... How much extra labor time might be involved in throwing a 3.8 in instead? I'd like 175hp and some 90 degree torque in my 93 if possible, the car's in great shape and deserves an -other than stock motor- if I can afford it. $200 for the delta is a hard thing to pass up. I'm gonna search these forums a bit more for some more info, but in the mean time, does anyone have any good points to bring up about this possibility? I'm no 1/4 mile whore, or a dyno addict, but I love luminas, I own 3 of them, I drive them hard, and they serve their purpose great. Quote Link to comment Share on other sites More sharing options...
ragejg Posted June 18, 2005 Author Report Share Posted June 18, 2005 Ok, I've done some searching, and am getting the impression that my present wiring harness may in fact be compatible... Also, oddly, my tranny in the 93 is the 3-speed... for some reason I liked it when the car drove, and it seems that the final drive ratio was different than in my other 4 speed luminas... I understand that I may have to do some relocating as far as battery/WW fluid/intake box... this is not an issue. I'm more wondering if the garage would be able to grab their shop manual for a 93 regal with a 3800, and act like theyre simply replacing the motor in one...

ragejg Posted June 18, 2005 Author Report Share Posted June 18, 2005 Hmm, after more looking, I'm having trouble finding info about that 3 speed tranny... is it as strong as the 4 speed? Could it take the extra power of the L27? I know, I've posted 2 replies in my own thread... heh... and I have seen similar threads to this, but none dealing with the possible price differences between a 3.1-3.1 and a 3.1-3.8 swap, and none dealing with the 3 speed tranny... Thanks in advance for any help... Quote Link to comment Share on other sites More sharing options...
digitaloutsider Posted June 18, 2005 Report Share Posted June 18, 2005 The 125-c would be toast with a 3800 next to it. Don't bother. The 3800 wouldn't run properly with it anyway. If you want an L27 in there, take the 4T60 along with it. Quote Link to comment Share on other sites More sharing options...
ragejg Posted June 18, 2005 Author Report Share Posted June 18, 2005 I think the 4T60 is shot... maybe the 4 spd from my 91 would handle things better? Oh and for the record, I'd need a different radiator, wouldn't I? I do know that 2 of my luminas use the same raddy with the tranny cooler in/out... but the L27/regal combo probably used a different setup, didn't it... :? Thx for the fast response...

digitaloutsider Posted June 18, 2005 Report Share Posted June 18, 2005 You'll most likely need the radiator, but I'm not too sure. IIRC, the Chevrolet and Buick 4T60's are NOT interchangable, so.. you're sort of SOL there. Quote Link to comment Share on other sites More sharing options...
cutlassdude96 Posted June 18, 2005 Report Share Posted June 18, 2005 you will also need the engine mounts from a 3.8 Regal too Quote Link to comment Share on other sites More sharing options...

IIRC, the Chevrolet and Buick 4T60's are NOT interchangable, so.. you're sort of SOL there. The 4T60 is the standard issue 4-speed that is in the 92 Delta 88, and is also in my two 4 speed luminas, right? I'm not up on the trannies as you can tell... ... ...EDIT... allrighty, the 4T60 is the pretty much across-the board tranny... with the "E" coming in the mid-nineties mated to the 3100 and the series II 3800, right? And CRAP, I really don't know if the particular 4-speed in my 92 euro (with the transplanted 91 buick 3.1) came with the buick motor, or if it was a carryover... Hmm, ya know what, after some contemplation I'm almost 100% positive that only the buick MOTOR made it into my 92 euro... ... so with that said, I am now under the impression that my 93 Lumina could accept the 92 L27, but the 125-C needs to go... (it's kinda a shame, I sorta dig its shift points) ... and my 4T60 from my 91 should do the trick... ... sounds like I'll need a 93 regal 3.8 EEPROM, right? ... and what exactly is so weak about the 125-C? Is it an ancient design that was originally only meant for 4 cylinder Citations or something? ...and the 125-C refers to both the TH125C and the 3T40, right?

ragejg Posted June 19, 2005 Author Report Share Posted June 19, 2005 Hmm, I've decided what to do... The 91 Buick motor's going into my 93/125-C... The 92 euro's getting trashed save for the trunk and maybe the insturment panel... And... I'm gonna get the 92 Eighty-Eight L27 to put into my 91/4T60... So... I'll need motor mounts, a radiator, and a computer from... what, a 91 Regal 3800? The car needs a motor, and if it's only gonna be a couple more hrs labor vs putting a 3.1 in there, then I don't see why not on the decision to put a 3800 in there... I just wanna be prepared with the right information when it's finally time to do it (probably this fall or winter)... Quote Link to comment Share on other sites More sharing options...
