Measurements of trans and engine

Post by idreamidrive »

First off i would like to say hi and because of this site i have been thinking about dropping in a 4g into my 1990 miata.

i was originally thinking about doing a 3sgte, but sourcing parts for that swap is almost impossible

could you guys measure the front of the engine to the back of the tranny, the front of the engine to the back of the engine, and also the height and with of the multiple trannies that now bolt up to the wonderful 4g.

if this is asking too much, sorry. but i want to make my life a little easier than it will be in the coming future

the 4g63 should be a inch or so shorter im guessing.
You get extra 12mm of stroke, so it is 12mm (or just under 1/2") shorter :wink:

4G63 is 19" long, from the tranny mounting surface to the front of the timing belt (accesorry drive pully is extra, depending on the number of belts that you decide to use).

19.5" tall, from oil pan mounting surface to the top of the timing belt gear.

And the oil pan is 5" tall (with a dry sump set-up you can get it down to ~2").

Its actually 12mm / 2. The deck is only 6mm taller.

Getting the engine bolted in is about 10% of the way there.
The next 80% can go quickly with help and skill.
That last 10% takes about as long as the 90% that came before it.
