the uglier Supra...

And here is my Supra. Not comparable to Reign_Maker's ofcourse but maybe one day. The 18" Konigs are no longer on it. I bought it without them with the intentions of buying them later on and now I can't afford them. I've also since spray painted the car which turned out terribly I might add. Dupli-color is garbage! It was supposed to be glossy black. It is like 2 shades darker flat black than it is in the picture. Mods are a catback exhaust with a dual tip muffler which only cost me $175 plus tax at Jet Muffler in Crestucky!!

There is alot of potential there man... Throw a GTE in there and keep that bitch wingless! I love turbo wingless supras...

Oh, and dont be so hard on yourself or your car man... Please dont compare it to mine by saying yours is the uglier... My car didnt wake up over night lookin like it does, it just takes a lot of time, money and patience... You will get there... Dude, Ive been working on my car for just over two years... There are guys who have taken 5+ years to build the car they want... I just dont want you to feel inferior man, because you arent... It may take time, but you'll get her where you want her to be...

All Supra's gotta start somewhere right Jake? I also have a MKIII Supra. I just put up my build thread. Check it out.

LOL! What do you have against spoilers man? I like the factory turbo wings. I also have a rear louver that was on it when I bought it but I snatched it off until I can get it and the car repainted. I'm gonna clean it up and paint it dark flat black and hopefully paint the car a nice glossy black to match my truck.

Nothin against spoilers, but if you put one on, get an 89+ wing like mine or one like Andrews... The pre-89 spoilers are horrible... I love wingless too, because all turbos came with spoilers, so when its turbo and no spoiler, its sleeper... What I really love is wide bodied MKIIIs that are wingless... MMMMmmmm!

Definately, I've seen a couple pics and damn, it looks good.

Get your hopes up on the supra man, there is a lot of potential, hell, a JDM swap for them is cheap.

There ya'll go again with "JDM", LOL! The motor was built in Japan. It is JDM. Thanks for the compliments though. I wish it had a paint job and some wheels. Like I said the 18" Konigs aren't on it now. Also the rattle can job I did turned out all kind of horrible. It basically doesn't even look like I painted it.

I'm also not making enough money at this job to actually afford to do anything to it. Heck I was supposed to be testing the TPS a week ago and still haven't done it. Don't own a multi-meter and don't have the money to buy most of the stuff I need (minus the TPS Reign_Maker is giving me). One day though!

thanks dude, I tried to call you about this car for like a few weeks...now I drive an eclipse non-turbo.

LOL, you weren't trying to call me cuz I'm the cool guy who bought it. There was another one in Destin for sell for $1,000 at the same time.

Anyways be glad you didn't buy this. So far it's a money pit. The moron I bought it from lied his but off about it. I already knew that was the case when I was buying it but I just didn't know what all he was lieing about. It'll be straight though once I get the money to replace a few parts here and there.

Supras are money pits... But most cars that are 20 years old are, especially ones that are controlled entirely by electronics...

MUST.......................PAINT..................................SUPRA........................Ahhhhh NOW!

what kindaparts you need for that beast? i have a bunch of stuff for them. I like that bodyslyle, they have a clean look about them. I have built 1 N/A and 2 turbo MKIII's so far and they aint that bad to work on either.

Hehe, I was actually asking you about yours in your introductory thread, LOL. Yeah obviously I don't have the money to do much to her right now but as soon as I can get around to testing the TPS, I can figure out whether or not it'll have to be replaced. Reign_Maker said he's got a good one I can have so I'm set there. Gonna have to rewire the knock sensor and most likely replace it. I'm really trying to get all of the bugs worked out of her right now. Once I get it running good and make sure it's reliable I'm gonna pretty it up just a tad. One day I might let nismodude paint it and I'll put some decent rims on it. Then I'll start saving up for a 7mgte. Reign_Maker also told me he knows a guy who has a junk 7mgte for sell for $50 but I guess he's still checking on that. We'll see.

Nothing but plans for now though...

I have a 7mgte at the shop with a spun rod bearing, it was a running engine though. I have a 7mgtet also, but it was improperly rebuilt by some kids and it threw a thrust washer and ate up the block. it has all brand new head, pistons, rings, all the rods were still good, basicly it needs a new block. I also have the supra t3/t4 turbo for that engine but it needs the turbine bearing replace, it has some shaft wobble, I have a stock t3 also that needs an oil seal, it was dumping oil into the exhaust by the gallons. you can have that 1 if you want to get it rebuilt. as far as your car, whats the problem that you think the tps is causing?

I've only had the car 2 months and it's a long story already but you asked so buckle your seatbelt.

When I bought the car it was missfiring at idle. It didn't missifre while you were driving it but once the rpms got back down to idle it was missfiring again. I drove it like that(just around town) for a while with no problems and was just enjoying it for what it is up until a week and a half or so ago. I decided it was time to finally check the timing and see why the heck it was doing this. The car was basically advanced as far as the distributor could turn. We're talking like 30*-35* before TDC or thereabouts. I cranked it down to 10* before TDC which is where it's supposed to be according to the Toyota info sticker on the hood(they thought if it all didn't they?) and the idle was... near perfect. Standing in front of the car with the hood popped I could still here a slight muffled pop(missfire) about every 3 seconds or so but once you got in it it was great. Revved nicely and sounded awesome. Took off down the street and NO POWER/TORQUE at all! It wouldn't even accelerate past 3000rpm with my foot beared down on the throttle. In fact it drove better with only an inch of throttle and no more. Took it home and advanced it back to 15* before TDC, drove okay. Missfire became a little more noticeable but still not noticeable in the car and it seemed to have 60% of it's power back. I drove it a few miles like this and it was enjoyable still but not right so I left it parked for the last week and a half or so. Cranked it up saturday to take it to work just to knock the rust off the brakes and it was as bad as it was worse than it was when I had the timing set to 10* before TDC! I had to lap the block and park it back in the yard. It's like there is no fuel getting to it AT ALL when you mash the throttle. It was also idleing a lot lower than normal when I started it up the other day. It was idleing at about 1000rpm when I parked it last and saturday it was idleing at about 500rpm but wasn't stable.

The plugs, wires, cap, and rotor have all been replaced by the guy I bought it from. I haven't checked all the plugs to make sure they have been replaced(probably should). I did check #1 because I had to take it out to verify which mark on my crank was TDC, and it looked weathered due to driving it around with problems but obviously had been replaced relatively recently.

I read on SupraMania how to test and recalibrate the TPS so once I can afford to buy a multi-meter I'm gonna knock that out first and foremost. I'll be buying one this friday or saturday and will probably test it this weekend and go from there. I do have 2 check engine light codes on that point to the TPS so I'm sure it's bad.

have you checked the cam timing marks? if 1 of the cams is off about a tooth or 2 it can cause this problem also. another thing I have found alot is the pins in the plugs in the engine bay (every connector you can get your hands on) vibrate loose and get bad or weak connections. You have to separate the plug and inspect both side for the pins pushing out. wich could explain why it seems like no gas also. the OBD system in those cars is very unreliable. Everything is linked so that a tps code can come from a misfire. its good cause you can use the data screen with a scan tool for diagnostics but other than that it sucks. another way to check your tps without a meter is by putting a jumper wire between the low and high side terminals on the plug. if you jumper them together and it fixes the problem then you have a bad tps, if the tps is good and you do this it will usually cause a weird idle or the car can stall. this is just to test it though, you can use your toyota book to see which wire are wich.

Yeah I don't own a Toyota repair manual. I've tried skimming through the TSRM online but it's so incomplete it's hardly worth looking at.

Your the second person who has told me it could be one of the cams improperly timed but as far as I know it's never been taken apart. Can they get out of time on there own? Seems like someone would have to take them out and then incorrectly time them putting them back in but the car was stock when I bought it so I doubt anyone has fiddled with that. Still I reckon it couldn't hurt to check. I'm gonna test the TPS first.

If the knock sensor isn't working or is unplugged do you think it could cause any of this? It was unplugged when I first got the car and I plugged it in but didn't notice a change at all. Also the plug doesn't click into place. It just poked on... think the clip on the plug is broke.

if the timing covers have never been off then its very possible the cam timing is off, between dryrot from age and wear from mileage the timing belt can get loose and slip a tooth on its on. that would explain why it ran bad when you cranked it the other day. your distributor/crank sensor runs off the exhaust cam, so if that cam slips a tooth or 2 your timing is gonna be way off.
the knock sensor will set a code but it wont really effect the way the car runs if its all stock, it is supposed to tell the ecu if the engine spark knocks from bad fuel or whatever and the ecu advances or retards the timing a little to get rid of it. I have run them disconnected and the only thing I noticed was a ck eng lite.
if you go to autozone.com, they have alot of free wiring diagrams in there DIY section

Well I'll be sure to check the cams then. Heck I may just rip the timing cover off and slap a new timing belt on there so I don't have to worry about that crap. I need to go on supra mania and find out how to align the cams I guess. I'll check that stuff next week when I've got some spending money.

Thanks a lot for the tips and I might hit you up whenever I have the money to start thinking about buying a 7mgte to rebuild.

I can email you the timing mark info tomorrow, I have alldata at the shop. just send me a message with your email address in it. if i remember I will send the tps info also

Put a 350 in it, lol

Okay so today I advanced the timing a bit so now it is at 20* before TDC and it drives great. Not perfect but it's got plenty of power again and isn't bogging down. I think you might be right pjsj26. I think if the TPS was bad it would have the same problem no matter what the timing is set to although it would obviously be worse under one condition or the other. I'm still gonna test it cause like I said, I have 4 codes coming up and 2 of them point to the TPS. But I'm also planning on tearing the timing cover off and replacing the timing belt.

Got another problem though now. I checked the coolant reservoir and it's got oil in it.... and no small amount either. I couldn't pull the radiator cap off cause I just finished driving it but I checked the oil and it's clean. Last time I popped the radiator cap off and checked to make sure it was full, it was both full and clean. Not sure if maybe it had a blown headgasket at some point recently and someone fixed it or if it currently has a blown headgasket. Either way it looks like I'll be getting my hands dirty coming up soon.

you know, those cars are notorious for crackin heads and leaky head gaskets. not to sound bad or anything but it sounds like someone realy beat the crap out of that car. no worries though, its just nuts, bolts and time to fix. almost sounds like you have a heat crack in the head, in wich case you would only see it when the engine is warm. but then again it mite be nothin at all. need to warm it up and do a pressure test on it to be sure. if its not over heating or anything i wouldnt get to upset about anything yet. see if theres a reputable shop close to you that can do a cooling system pressure test and maybe a block leakage test. just ask for test only, I know at my shop we wouldnt usually charge anything to check it, if we did charge it wouldnt be more than 20 or 30 bucks. if you were closer to fwb I would do it for you. as for the timing issue I still say it sounds like a tooth or 2 off on 1 of the cams. you shouldnt have to crank it up to 20 degrees to smooth it out unless it has some race cams in it. let me see what i got happening this weekend and maybe I can come out there and look at it. i will let you know

Well I work Saturday and I'm at church most of the day Sunday so getting together to work on it can't happen anyway. I really appreciate the offer though. I may call around and check to see if anyone can check that stuff out for me for real cheap. If not I may just buy a compression tester and a cooling system tester and do that myself. I've done the cooling system checks before when I was an apprentice tech at Lee Imports. Never checked the cylinders for compression before but I've talked to enough people about it I'm sure I could figure that out easily.

I don't think this has a cracked head. Maybe a blown head gasket but I don't know. It drove it all over town today and it runs like a champ. We'll see.

If somewhere down the line I do need a head do you have a good one for a 7mge? Don't know if the year makes a difference.
