hi all
i'm planning on changing the pinto in my kit car to a z20let i've already got over next winter.
i believe this is the same block as used in the x20xev and possibly the c20xe and c20let (not 100% though)
sooo, if this is the case i know it's possible to attach it to a type 9. i was just wondering what off the shelf parts i'd need.
obviously i'll need a bellhousing from the likes of yukspeed or SBD.
i guess my question is what flywheel + clutch + clutch release mechanism options are there?
anyone done the conversion and can give me a nudge in the right direction? part numbers, diagrams, pictures etc would be brilliant.
thanks,
andy
SBD would be the people to ask. I'd be more concerned with breaking a type 9 pushing 200HP and lots of torques thru a T9.
x20xev and c20xe/let block not identical, but gearbox connecting the same.
fly wheel used opel, but 230 mm clutch disc i used from ford galaxy 1.9TDi, 2.0, 2.3, 2.8 (same tooth like t9 or mt75).
due to higher strength as using mt75 gearbox, cut and welded opel gearbox front
You better use t5 gearbox, but expensive and hard to find....
If its a light weight car like a Seven a type 9 is fine with up to about 250 bhp. In a heavy car like the original Sierra donor there is no way it
would cope with that power.
At the end of the day its revs that kill a type 9. Up to 7500 they are fine but over that you need a modified one (Quiafe Pro, Tran-X, Steve Perks)
where the gears on the mainshaft run on needle rollers.

I am building a Z20LER (Lotus Europa S engine) based scratch build with a heavy duty Quaife type 9 and a bell housing from Zukspeed.
The standard type 9 is supposedly only good for 140 bhp so you really need a heavy duty box. One problem is that the bell housing has to be modified
to take the larger lay shaft bearing housing on the HD gear box.
The other problem is that the Z20LER has a dual mass flywheel which won't fit inside the bell housing. The crank / flywheel is 6 bolt pattern and
the X20 / C20 is 8 bolt so it is not a straight swop.
There are lightened flywheels available for Z20 engines but they have upstand blocks on the rim which takes the clutch pressure plate to the same
height as on the dual mass flywheel. It may be that the solution is to get one of those and machine the blocks down to suit.
That bit I haven't quite sorted yet. I would be keen to see any ideas you get given.
ore use early c20ne 6 bolt fly wheel (flat) - one mass and lightweight, pressure plate use from early c20xe - allow use 230mm the clutch ( clutch
disk from ford galaxy)
or use x22xe (frontera) one mass fly wheel (6 bolt) and pressure plate (but he is higher and weighs more)- allow use with 240mm clutch ( clutch disk
from ford trasit, sierra, scorpio..)
Due to the height, i do not know which is better

vauxhall omega box bolts straight on and holds 400+ hp in a 1000kg car, drag racing, we've done it.
Type 9 in standard form will last one standing start if that (in my experience, in a heavier car than a locost admittedly!)
Type 9 with quaife pro kit might last a few more, but still only rated to 275hp, and 400hp on an LET is dead easy!!
We've just seen one make 425hp on standard bottom end, stock pistons, standard cams etc, just fabricated inlet and decent exhaust manifold plus
bigger turbo.

hi all
thanks for taking the time to reply.
sounds like i need a trip to yukspeed. only 10 minutes from my house so would be rude not to!
the omega box looks miles too wide for my tunnel so i dont thnik that's an option really
sounds like a t5 g/box would be the sensible option. i cant see me wanting more than 250bhp from it, but who knows. i think i'd better future
proof the install by going for a tougher gearbox.
will report back with any progress
thanks, andy
picked myself up a t5 gearbox from london a couple of days ago.
been in touch with SBD and they've recommened me a 6 paddle clutch and uprated clutch cover for a not too expensive price so think i'll go
with that come payday.
and a vauhall to t5 bellhousing is on the way from RWD motorsport
only thing that does concern me is theres quite a bit of of side to side play in the t5 g/box input shaft. will have to investigate
will keep this thread updated
Also went that route ^^^,bomb proof if in good condition.
