high power dream, transmission impossible?

[Rabbit on Roids]

the rollers start skipping around 7-7.5k rpms. they simply cant go any higher than that. kev, why dont you just fit a inline P pump off a 4 banger cummins or mercedes engine? that would give way more than enough fuel. its not gonna be even remotely close to bolt on and go, but you should be able to make something work if your gonna graft this into a mr2.

I have a friend with an 02m (6 speed, 2 wheel drive) out of an 03 20th anniversary gti for sale, with shifter box/cables/clutch/everything and is asking 500 I think.   Shipping would be the hard part.   This is the tougher of all the transmissions listed in this thread.

I wonder if stronger springs inside the pump would counteract this, as heavier valve springs would in a head?

[macka]

maybe but how would heavier springs affect the initial fueling?

[8v-of-fury]

yeah i came to that thought afterwords... I have no idea, I'm guessing a higher internal pump pressure would be needed?

[Rabbit on Roids]

the springs are closely matched to the pump head assy. thats why bigger pumps dont run well when people swap in 10 or 11mm heads and use 9mm springs instead of the tougher springs that are set up for the 11mm head.

ooh!  me want PM sent

[Rabbit on Roids]

and an 02M fits on a diesel bell housing this old?

[NintendoKD]

it's an 02q out of the next generation car MK5 should bolt up still right?  this is also a cable shift tranny and will ork with the cable shift setup of the spyder

All transverse VW 4-cylinder bolt patterns are the same.  4-speed, 5-speed, and 6-speed.  That's all 4-cylinder engines too, 8v, diesel, TDI, 16v, 1.8t, and even the 2.5 5-cylinder.

There are some differences with flywheel mounting and clutch splines but that's easy stuff compared to everything else that's needed with a tranny swap.

i thought the 2.5 was actually different,  josh at nls had to do some weird stuff to make it work in the rabbit, he did use an 020 but it wasn't a direct bolt on

[NintendoKD]

what stuff has to be done to the flywheel tranny spline?  I plan to lighten whatever flywheel I use to a rediculous degree so this info in advance would be of tremendous use now.

[Rabbit on Roids]

you just gotta bolt the appropriate flywheel/clutch/pressure plate on the engine that is particular to that transmission. shouldnt have to modify the input shaft splines at all...

So you're saying the added force needed to shove the plunger would make the roller cage fight the internal pressure. I think it would but I bet that could be fixed with bumped up internal pressure.
