Finally have the EJ20 twin turbo in my garage but no affordable 930 transmission after over a month of making calls and searching the net (can't afford a +3000 Euro trans right now).

Should I risk putting the EJ20 TT on a late bus trans(>'76) and go a little bit easy on it until I find a 915 or 930 box or would that just be a waste of time and money?

Thing is the bug is currently my daily driver (+ the car from work but that's just to get to and back from work) and I wan't the turbo engine in as fast as possible now, it has taken long enough as it is.

If I were in your position, I´d do it if you got the bus trans anyway. Ride it till it breaks and find 915 or 930 in the meantime. What are you loosing anyway? Go for it.

I don't have the bus trans yet but I'll propably be able to get one for around 200 Euro.

Hook in son!!:thumb

yesdo it for now,
if you want to get the engine in the car then do it the bus box can handle a fair bit of punishment, i gave mine a bit of abuse and it was behind a 4.4L V8 it was going fine. then i fitted a 915 trans
cheers

Just use the Beetle box! They can cop a fair bit of abuse...

i would go the bus trans........and then take your time looking for a good 915 or 930 trans

As discussed in length here before, and as Jak, myself and several others are doing...just use a single side plate late beetle box. Jak uses his as a daily driver and races anything that requires embarrasing, and his has not missed a beat!
Everyone freaks out about the box not handling the power, although we have not yet heard of one shitting itself in the early stages of any daily driver conversion.

I'm with Jak, go a 1303 single side plate box. A good mate of mine who's a kombi specialist says the 091 2l boxes have the same size components as the 1303 box anyway. He swears by them. Just have a tuff one built up later if needs be. Cheaper and easier than a porsche box any day.

over here in perth. to get a kombi box that could easily handle my 300rwhp target was gonna cost about 6k. whereas i found a place over here that charges 5000 for a porsche G50 box. i know which option im going for.

Handling 300rwhp is only relative to the way you use or abuse the hp. I watched Jaks car do power run after power run on the dyno and he has been racing everything he comes across...gives them a rolling start and stands on it! It always looks more inpressive when you overtake them before crushing them. The little use my car has seen, has also shown no faults with the 3.88 box.
Unless you are regularly giving the car 6000 and dumping the clutch, the vw box with a few mods is fine.
If you have $5k spare and the to make the porsche box fit then sweeeet!

yeah. as this will be only a weekend car for me. then i will more than likely be squashing many a ricer. its a cruise car/weekend warrior.

but i will run the ssp box that i just got standard until it brakes. then put the g50 in. i was simply saying that to get a box that can handle the power AND the abuse. it works out cheaper for a porsche box.

this friday I should have a '78 bus box and transaxles for a good price so might be mating box and engine early next week
