verse Posted August 10, 2004 Report Share Posted August 10, 2004 You could find an MK2 Supra 5MGE for pretty cheap, sometimes on Celicasupra.com people give them away. Or even an MK3 Supra 7MGE could be found for not that much money. Good strong motors. Quote Link to comment Share on other sites More sharing options...
Guest mudbutt Posted August 10, 2004 Report Share Posted August 10, 2004 The 7m-gte headgasket issue is due to low torque specs. Tighter ARP bolts will do you fine, add to that a metal headgasket and you are golden. Stock internals are reliable over 400 (some gone over 500) with issues of the shitty oil cooling system addressed. They are plentiful, cheap, easy to work on and easy to find parts for. If money were no option then an rb26 or 2j would be superior. Quote Link to comment Share on other sites More sharing options...
Avenger1647545502 Posted August 10, 2004 Report Share Posted August 10, 2004 I'd go with the slant-six myself, but I'd be wondering about fitment issues. They do lean over a bit, you could end up with the same type of clearance issues, but only on one side. And since the \6 was never available with FI in the States, and the Mexican/Brazil versions are a little tough to get, you'd have to go carb'd. Unless somebody has made a plug'n'play FI kit, and I'd hope that would have been in at least one of the Mopar mags! Quote Link to comment Share on other sites More sharing options...

I haven't seen Dave's car yet, but there is a good chance it won't fit. Also, those being a new engine that is only put into one vehicle that isn't selling that great, the chance of finding one is nill, even compared to a 2JZ Quote Link to comment Share on other sites More sharing options...
Dave1647545494 Posted August 11, 2004 Author Report Share Posted August 11, 2004 lots of good ideas here I'm for sure in the early research stage here so I'll be looking into all alternatives. ideally I'd like to start with a totally stock setup make it all work in the car and then mod from there. the car also needs a complete interior resto and paintjob so its going to get a it'll start and run drivetrain to begin with. lots of different stuff here I apreciate all the info thanks Quote Link to comment Share on other sites More sharing options...
SupraGlue Posted August 11, 2004 Report Share Posted August 11, 2004 I like the Trailblazer six or the Ford that Eli mentioned. Cruisers love cubes, and those motors are both as state-of-the-art as any of the Japanese motors. If you want to go with an older carbed motor, Pontiac had a performance I6 in the Tempest in the mid-60s (Sprint Six, maybe?). I have no idea where you'd find one or what it would cost, but that would be an interesting motor to have. Quote Link to comment Share on other sites More sharing options...
Guest Dark_Viper01 Posted August 11, 2004 Report Share Posted August 11, 2004 I would also say go with the 225 aka 3.7L slant six, one of the most reliable engines ever built. I had on in my old ram, it's up to 312,000 miles now. It's never been rebuilt, and runs fine. It's outlived 3 trannys though. They do make EFI conversions, and there is a good sized aftermarket for the 225. I know a guy with a 72 duster running 8lbs of boost on stock internals for the last two years, and he hasn't had a problem. There is also something to be said for sticking with mopar.

Guest jpurdy2003 Posted August 14, 2004 Report Share Posted August 14, 2004 My mom used to drive a slant-6 1970 Dart last year, and while it had decent low-end torque, it fell on its face above 3500-4000 RPM. Quote Link to comment Share on other sites More sharing options...
Dave1647545494 Posted August 14, 2004 Author Report Share Posted August 14, 2004 slant six won't fit leans too much has to be a straight up and down motor I also have plenty of hood clearance as the motor sits low in the chassis Quote Link to comment Share on other sites More sharing options...
Guest mudbutt Posted August 15, 2004 Report Share Posted August 15, 2004 How much width do you have to work with? I can measure my 7m for you. Quote Link to comment Share on other sites More sharing options...
Dave1647545494 Posted August 15, 2004 Author Report Share Posted August 15, 2004 rough guess is about 36-40 inches between the fender wells Quote Link to comment Share on other sites More sharing options...
Guest mudbutt Posted August 15, 2004 Report Share Posted August 15, 2004 Roughly 31" between strut towers Quote Link to comment Share on other sites More sharing options...

Guest mudbutt Posted August 16, 2004 Report Share Posted August 16, 2004 depending on what tranny you use, I know people have adapted powerglides to the 7m, so Im sure something else could be made to fit if desired. If you arent wanting over ~ 300hp then the stock auto will work, though it isnt the greatest(wont get into this debate again smile.gif ) The motor is fairly cheap to upgrade to around that power point also, and up to 400 can be done relativly inexpensive. Past that things can change. If you need any help locating a motor or associated components, I will try to be of assistance. Quote Link to comment Share on other sites More sharing options...
copperhead Posted August 16, 2004 Report Share Posted August 16, 2004 the manual tranny that mates up to the turbo 7M, i think it is the R154, will hold up to pretty much whatever you can get out of the 7M motor auto = weaksauce Quote Link to comment Share on other sites More sharing options...
Lustalbert Posted August 18, 2004 Report Share Posted August 18, 2004 292 chevy straight 6 there is a good aftermarket for them, especialy in circle track also 4 bbl intakes, so you can put holley 4di system on it, and you cant help but fall over a gm trany just by walking into a junk yard Quote Link to comment Share on other sites More sharing options...

Guest xxxyyyzzz Posted August 22, 2004 Report Share Posted August 22, 2004 Cummins. What?! It's only 5.9L, plenty of power potential, and they're swapped into other vehicles occasionally...
