T9 or T5 in MK Indy R?
I am debating putting a T5 or T9 behind a Duratec 2.3 in an Indy R, I am based in the US where cheap T5’s are readily available and am concerned about
the durability of any T9 that I bring over with the kit, however I am not sure if I will need to do any mods to the kit or loose space in the cockpit
(especially legroom) if I use a T5.
Comments???

I have been putting 300bhp through a type 9 with no problems for the last 2 years so would go for a type 9.

Depends on what power you want to run and how much room you have in the chassis.
T5 should be good up to about 400bhp as standard. Not sure about the US, but in the UK they go for about £300, and have a half decent (2.95:1) first
gear ratio as standard.
Type 9 (standard) seem to die at about 200bhp / 200lbft in my experience (lots of synchro problems - but then I use £25 second hand 'boxes!),
and have crap ratios (3.65:1 first gear). The stronger remanufactured Quaife / BGH / TranX type 9s will set you back over £1000, and are supposedly
rated up to about 300bhp. You get to choose ratios for that price!
Size wise - I've just swapped a T9 for a T5, and there's surprisingly little in it. Same length (within an inch), but the front of the
gear casing is maybe a couple of inches wider.
Weight wise - judging from feel alone, a T5 is lighter than a standard T9, probably due to the ally bellhousing. T9's is steel and weighs a
ton.
Let us know what you choose!

You will loose a little bit of legroom. To get my type9 (and Vauxhall XE engine) into the Indy-R, MK had to move the bulkhead the pedals are on back
by 3 inches to make the engine bay long enough. The front of the transmission tunnel has also been widened a wee bit, even so it's a very tight
fit.
I still fit in fine though, 6ft tall. I'm using the MK fibreglass seats and there's still a bit of room to move the drivers seat back a
couple of inches.

in a car a type9 is not the strongest option but when u put it in a kitcar u have a third of the waight to push so the type9 ends up a strong box if
it were me id go for type 9 and u will need a ally bell housing any way to fit it to duratec so will be lighter than t5
some people dream of sucsess, others just get on and do it !!
