Where is the engine made?? should be on one of the labels under the hood?? chip---gearing??? yes if you do a little research on exactly what kind of "performance " you want and how to best get it.
sycronizer probably going out since that gear is primary when gearing down from 5th
All depended on the engine in it and rear gearing.
That would all depend on the size of your engine and your rear gearing.
That would depend on what year of Ford Ranger and what size of engine it has
Which highest performance Toyota engine would fit in my 1985 Corolla
That would depend on the engine size , automatic or manual transmission , what the differential gearing is , etcetera
A better question is why would you want to put a ranger transmission on a mustang
The main compatible engine with a 1999 Ford Ranger would be a 4.0L Ford V6. A V8 engine would fit well as well, but uses a lot of gasoline when driving.
Most likely would be the 2001-current 4.0L with the SOHC engine. The best looking one is the 2005 Ford Ranger STX with the same engine.
I would need to know what size engine you have and what year of Ford Ranger in order to answer your question
No it would not. Transmission performance does not affect the engine. But engine performance does affect the transmission.
It would definitely help keep the engine from overheating.
