1987 mark iii 7m-ge i6
 

Hey evey one, new to the supra world, and wanted in. i have found a 1987 Mark III with only 45,000 miles on it. old man only wants 2500.00. but heres the questions. WHAT AM I GETTING MY SELF IN TO!!!! i have worked on cars my whole life, I can do just about any thing and evey thing to a car. but i have never messed with a supra or a import car of this age ever, seeing how i was born in '87. but i am just looking for a project car that i will have a fun time working on and a fun time driveing. another question is how hard are aftermarket parts or OEM parts for this bad boy going to be. and how what is required for a turbo upgrade on a 7M-GE I6. where do i fine out what Transmission it is, 5-speed W58 manual 5-speed R154 manual, all i could find on the trans/eng was this HT43.0V5FBB1 , does that make any sence to any one? but thank u for the help ahead of time. here are some pics as well!

First: make sure the thing runs and doesn't have a bad head gasket (very common if your not fimiliar with supra's).

Second: from looking at the pictures I would bet it has ALOT more than 45,000 miles on it to have that much paint fade and interior damage.

It could only have 45,000 on the motor and if it's been sitting out side all these years will do that to the paint And the 7mge comes with the w58 the 7mgte has the r154

With that low of mileage, it probably sat a good bit of the time. So every hose, gasket, belt, seal, and bushing should be considered. Some times a car that was driven with more miles is better than a car that sat for a while and was driven less. It could be a nice project car if that what you want but that paint and interior look like they have seem better days. Just keep in mind that a 7mge with a w58 is not that special.

Thank you for all the help, and the car runs and drives fine. With the eng I have can u get the turbo and the headers and make it a turbo and any one mess around with a twin turbo on the mark III's any info on that would be great! I'll keep every one posted on what's going on but as of now it's half way striped down only thing left is the rear end and the dash. I'll get pics up soon thanks again!!!

theres alot more to it than that brother..
who has that damn link to the conversion page..

oh the good old hoed out link
http://www.4cefed.com/conversion.html

I wouldnt drive that car at all untill all the the gaskets , seals hoses were changed out... flushed rad, changed oil...defiently new filter.. BRAKES for god sakes..

do yourself a favor and just save up for a 7mgte.. still all the fun of a project car with half the battle.. but im an NA hater..

Ha, I have messed with turbo and twin turbo a bit on newer cars but my back round is more of superchargers. What is the positive side of having 7mgte, because it already have the turbo? And is that block for the 7mgte considered a long block? And Green That link was nuts lol not even a page but all info no bullshit. And according to the man the oil, bets seals have all been replaced but I did trailer it back to the house, just in case. But I may be sticking to an N/A not sure yet ill do some digging around online and have a few of my buddies in Japan look for some parts and so on. But thank u again for all of the help, deff the place for me, hope every one have a great weekend, I know I will! Pulling the ENG and TRAN’s out today!

how ever i did find :bow: http://www.suprastore.com/7mgte.html :outahere:

nice. but with any motor.. just purchased or not you have to assume its been sitting in the elements for god knows how long.. always.. always do a rebuild..

If it sat that long and was just periodically turned on and then back off there could be a significant amount of damage from condensation: Pitted cylinder walls and eroded bearings.... just something to keep in mind. Was this still driven on weekends or just sitting in a garage for 5 years? At any rate, if you've got experience with rebuilding and plan on doing so it's no big deal.

oo belive me i just droped alot of money on hourse power freaks, bottom to top rebuild! but i did have a question should i get a ruber HG or a metal one? and what kind of pistions? and any one know were i can get a High VOL Water pump? and any one know the size of the belt needed with out AC! and whats a good cam set up? i have found alot just wondering what worked the best for people if you tryed out a few. and after market heads? do they even exist???????? sure have found alot of cat backs tho ahah! http://www.horsepowerfreaks.com/part..._Touring/10112
has any one messed with that exaust?

hahah its funny the more looking i do the more shit i find i forgot to order!! such as a bushing main kit! break lines big break kit! ahahah its starting to add up, Total is now at 5476.87 car not included! oo and as i was looking around any one know a sight for trans rebuild kit and/or trans gears?

Rubber HG? WTF are you talking about? Where on Earth did you hear of rubber head gaskets??? Your choices are: composite (like the stock one; single layer of metal as a substrate for compressed graphite), copper (generally only used in racing applications) and multi layer steel (MLS generally what is being referred to as a "metal HG"). MLS, steel shims and even some copper HGs vome with a VERY thin viton coating to act as a sealant, but this doesn't justify the title of "rubber HG".

Aha I'll post the link when I get home it was on eBay. I was thinking the same thing.

Only two possibilities: 1) joke/novelty 2) they're fucking retarded

My guess is a retard!!!:p

But to go back to your question, the man said it was started every weeke d and drove around the block. For 10 mins and basic shit was done.

If your going to rebuild the motor from top to bottom why not convert it to a NA-T. If your looking for cams the best bang for you dollar would be to buy a set of 7mgte cams and put them in your head. Oh and buy a metal head gasket and ARP head studs

Ok... just stop right now... I don't know who the f#$% you're talking to but they've no idea what they're talking about and have apparently missed all the threads, tests and the regular old fashioned physics involved in all the old wives' tales of the Supra.

There is NO difference in the GTE and GE exhaust cams. The only difference is a VERY small change in duration vs lift. GE intake cams on the GTE make it fall flat on its ass in the mid RPM and remains there. Running a GTE cam in the GE costs the N/A pretty heavily. You lose a very big amount of bottom end power and the N/A doesn't flow enough to make up for it (as the GTE does starting around 2K RPM). The GTE intake cam is a worthless upgrade... well, downgrade actually.
