gearbox problem... doh!

[Eternal]

As i knew it would be a massive bellhousing. I cant cut the rails as the chassis as is not fully welded yet. and i cant do any tunnel work or U3 or U4 till i know how far back i can get it.
Also its looking real high at the moment any ideas?

[Eternal]

also i guess i will have to mount the diff higher as well to have a straight prop?

don,t forget that the middle section of BR10 gets cut out ( between U7 & U8),

cheers

the bottom of the gear stick( black rubber thing) is 330mm from the table. center of the prop shaft is 185mm from table top. top of the gear stick is 525mm. gearbox is 840mm long. and gearstick center(at base) is 100mm from rear.

would love to know some of your measurements from type 9 and mt75 would give me a good idea on where to put it. I have given myself self 60mm from the back of the gearbox to the firewall.... this will allow the pully to clear the BR7 but it might sit above it im unsure yet lol

I might have to cut the top bit of TR8 out as well and add another bit above it. Anyone done this before?

Thanks just seen your v8 height thread. dude that engine is massive. Im really worried about the dif to be honest. its going to be a nightmare to mount. =( the skyline dif is a 4.1 ratio do you think i can get away with a 3.9 sierra one instead or maby a 7.5inch cossy one? (RB25DET - twin-cam turbo (T3 Turbo) ~245 to 250 hp and 319 N·m) ~wiki) my one will be old so not that much power. it would save sooooooooooooooo much trouble,

Also can someone measure how high the center of the dif shaft center is from the table top? just so i can get the gearbox inline.

Thanks again all

Edit found out my gearbox ratios i dont have a clue at all about this kinda stuff all those cogs are confusing. So can anyone who knows whats what, advise me to the best dif for this 'RP71C #2', the ratios are 3.32, 1.9, 1.31, 1.0 and .838.

Sierra 3.9 will be fine, acceleration will be down a bit. Will handle the power fine.

TT

I would probably try and get a lower ratio diff than the 3.9. ive settled with the 3.6 ratio diff as i couldnt afford a 3.3. I have been told that the sierra diff will handle the power of my engine (200 bhp 210 lb·ft 280 N·m).

Hope this helps

I guess later i can get a quaife diff 4.1 when i got the cash. Would it be a load of work to put a 7.5 inch diff in? as i saw that the 7.5 inch 3.9's cost less than the 7inch versions.

Btw thanks for all the help guys
