Yes that does look good. I see you've still had to mod the bulkhead though, which I wanted to avoid really.
How much power and what is that gearbox?

Gearbox will be Omega - fits straight on to the B204/B234 engine (due to GM owning SAAB by then.

Just a little thought.....the future?
It seems that a lot of these modern mechanical bits can become obsolete very quickly. An example with me is the BMC A engine/gearbox. At the time of my starting a major rebuild on my Austin the BMC gearbox (Morris Minor etc.) was becoming almost impossible to get bits for so 2 different companies invented conversions more particularly for Morris Minors; one used the Ford type 9 5 speed box (which fouled a cross member on my A7 so could not be used; another used the Toyota T50.....a very nice box easy to open up and work on and horizontal rather than vertical size and this becam a very popular box for many applications (Spridget racing). Now I find that this wonderful T50 box is obsolete and spares no longer available and boxes are like the proverbial rocking horse s... One consolation is that if mine + a spare is any good it should last a very very long time with the modest power from the A series engine compared with the 1.5 Toyota engine output, and my use of Synionic Anti Friction Metal Treatment (AFMT) added to oil.

So as a summary just think long and hard about modifications or you may find yourself in the near future off the road for the sake of a small unobtainable part and have to start a new modification all over again. :(

Dennis......ps any donation of Toyota T50 gearbox or parts gratefully accepted.......bring them and have a self catering stay free in Devon.

Hi Dennis, I'm doing a engine / box conversion on my 5a and ive thought exactly the same. so ive kept the original engine / box as a backup; but my thinking is, if the omega engine and box does become unobtainable, then I will convert to another engine and box available at that moment in time ? its almost appreciating the shape but using a current engine philophosy.

Bulkhead mods could have been avoided, I just got a little carried away, the gearbox is a BMW M3 jobbie, power in its current spec will be around 480bhp


I break stuff...... :w

thats a lot of horses. is that simply down to a bigger turbo or have you done engine internals ?

Whilst driving home today I was musing over nitrous on my omega v6 3.2 and whether the gearbox could take it. (apparantly the engine is mucho stronger than the 3.0 version )

Try the stock lump first - the corners will come up a lot quicker already..

Yes, the 3.2 apparently has a forged crank (over the 3.0) so should take more abuse - handy for you :shock:

Is it the R32 box you’ve fitted? If so, that’s the limit - 320Nm. R30 box (3.0) is 300Nm and the others got the R25 (250Nm).

Anything over that and you’re into life-shortening.

Har har. :D

I now have the r32

Although I also have an Rx8 five speed and Essex conversion plate, it was tempting to adapt to the omega engine.
