Transmission tunnel help

[Eternal]

Hello all.
Have been doing research and im trying to work out what to do with the tunnel when i make the chassis. Seeing as there are quite a few sierras out there with MT75 gearbox;s should i just make the chassis to MT75 size reglardless of what donor i will eventualy get?
My question is... my endgame plan is to install a 13b engine and gearbox from a fc3s into the chassis i dont suppose anyone knows what tunnel size would be best to make this fit?

that looks a damn site smaller than a type 9. Is it in a standard width chassis? If so there is tons of room to spare with the standard tunnel dimensions. If you saw the size of an MT75 bellhousing you would see what I mean - it's huge.

Hi Eternal,

Its not easy to gauge from the photos but i reckon as that engine sits so far forward in the chassis I think you might be ok with a type 9 tranny tunnel, tho if you can get a width measurement around the bellhousing in line with the starter motor ( thats what i think it is ) I,d be able to give a more confirmed answer.

Also as i presume your car will be right hand drive then there is no reason why you couldn,t narrow the passenger footwell width a little, its plenty big enough as no pedals in there etc.

That way you wouldn,t lose "foot " space in the drivers footwell as you would if you fitted the MT75 tranny tunnel.

hth

The other thing is it looks like a very short engine so could be made to sit further forward so the gearbox would be even narrower at the point it passes the forward trans tunnel tubes.

That damn Andy beat me to it:D :D
Bloody bloke!!:D

I really cant tell from the site listed most of it is just pics. i guess you can work it out from looking at the chassis steering support position but im not that used to the chassis to be able to tell. I do know that the rotarys generaly sit a little forward so maby thats it? I got to get this worked out as its my main plan so any help research would be great! lol

Edit: lol loads of replys in the space of 1 min!

I just tried to post a photo but it's too big so it gets rejected. PM me your email addy and I will send a photo of the MT75 sat in a modded trans tunnel. I think it will give you the answer you need.

looks more pushed back. i guess it depends on where i want the gear stick...

Thanks for the pic mate yeah that thing is huge.

Can u guys have a little scan down this page and see what you think?

Some great pics down towards the bottom of the page.

looking at those pics, i,d say you,d be fine with a type 9 tranny tunnel , tho you may need to move the passengers side of the tunnel in a bit, just to clear the starter etc, but as yours will be right hand drive its not a problem for you.......

Type 9 tunnel me thinks, :) ;)

Hmmmm, me thinks that will work brilliantly. It looks like there is superb ground clearance and very low centre of gravity - all the weighty part of the engine is very low. I would think you would need a bigger fuel tank, I understand teh rotary drinks fuel like it's going out of fashion. The builder in that thread looks to be doing a superb job. Those rose joints don't come cheap, looking at some of the other build parts he aint doing it on a budget (me and Andy share one thing in common - we are both tighter than a duck's arse, which as everybody knows is water tight). Looks like a superb job, put's mine to shame somewhat.

Right found another build here. http://www.clowar.com/gallery/v/Locost/ looks like hes done a good job and the chassis looks stocko :D

Soooo all looks good... i think! :D
All i have to do now is just make sure the donor car has a T9 box not a MT75

Also just to show i found this pic on Turbosport.com
