7M-GE Motor not working as it should

[Colossus25]

Hi, I have an '87 Supra with a 7M-GE motor. It is not working the way it should. When I step on tha gas it takes a while to kick in and get speed. the motor sounds weak. IT starts out rough and eventually gets to the way it's supposed to run. Also, it's always overheating. Can someone tell me what is wrong with it or a reliable source for getting anothe 7m-GE motor? thanks!

Well, overheating could be anything from fan shroud to blown head gasket. Do you have any other solid symptoms?

[Colossus25]

Not really. Just the fact that it runs at low capacity. It struggles going up hills and when i step on the gas the motor sounds like its gona power down before it actually starts going.

As far as getting another 7m-ge, I know of a good shop in Vernon, CA (by Burbank) thats pretty good. PM me and i'll give you their number.

Buuuut.... I agree. We would need further info of your engines problem. Maybe a video?

Thanks for the info but as for the video, well, my car doesnt turn on anymore so i'm pretty much screwed. Luckily i live close to Burbank, I'm looking forward to visiting that shop. THANKS!

Makoto in Gardena is also good..

back when my 89 was n/a I had a JDM 7MGE swapped in, including long block, labor, new mounts, new radiator, spark plugs and wires, misc items, and a 6 month warranty it came out to $1200...

I have a 87 7MGE n/a (214K miles) that went through the same power symptyms last summer. The car struggled to get up hills. Replaced the plugs and wires with NGK's and its running fine now. Just a chance at a cheap fix.

Also, if you blew a head gasket you should drain your oil and see if it has a gray/brown milky consistency. A result of coolant getting into the oil via blown gasket. Also check the coolant for rainbow colors showing evidence of oil.

If ok, change the plugs/wires to NGK's.

Worth the $ to try.

did you get it swapped at Makoto..?


My car used to pull like a train once I got the engine swapped, because my original motor had 236,000 miles..
