    I have a MKlll non-turbo 7MGE. I went to start it the other day and there was no crank no clicks or anything. I can hear what I think to be the fuel injectors in the engine going on the key turn. I am fairly new to the automotive field and have a lot to learn so I figured I would look for some...

    I know, another exhaust forum, but I just wanted to ask a quick question. I have heard that for the 7mge you shouldn’t go above a 2.5” exhaust, but my car has a 3” on it. I have driven it with both the 2.5” and the 3” and have not noticed a power difference as people say there is. Only thing i...

    For about three months now I have been battling my car(1986.5 Supra NA MT). During the summer I let it sit for too long and the battery drained.

So I'm asking and hoping someone else has gone through this issue and has a fix for it. Its currently at a...

    Hi all, I'm new here. I received a 1987 Mk3 Supra 3.0i from my uncle today and I've got to say its not looking good. Pros: The interior was spotless apart from a small amount of mould on the rear seats. The car still had a good level of engine oil. Cons: The entire nearside A pillar has rusted...

    I am swapping a 7MGE into my project and was in the process of resealing the engine. I’m new to engine reseal/rebuild.
