#1 recomended clutch for a dellow toyota 5-speed conversion
steveo Posted on: 2009/3/16 3:47
Just want to know what sort of clutch plate fellow members recomend for the toyota 5-speed to A-series? i read some where that you need to use a toyota clutch plate and A-series pressure plate. Is there any clutch plate that can be used without modification? or do i have to get a clutch plate from Dellow?

I`m not sure what clutch plate comes supplied with the dellow conversion. I purchased one of these kits about 18 months ago and the plate that came just looked like any generic plate. I`m not sure whether toyota and nissan shared the same plate sizes though?
I`m interested where this thread will lead as the standard plate that came with my box has never been able to cope with full boost on my A15T.
I`m running a twin diaphram pressure plate from my old set-up and the std dellow toyo/nissan plate that came with box, I`m thinking I might modify my old plate (solid saw blade with full face asbestos friction material).
I know this probably does`nt help much but I`ll let you know if it works when I get around to pulling the motor (again?!).
cheers.

steveo, go to your local clutch outlet and get a clutch plate that is the same diameter as a a series one, but with the toyota spline.
its 190mm from memory.
you dont HAVE to get one from dellow, they are a pretty common thing and your supplier will have one on the shelf.
ive had one behind my a series for a while now and it still dont slip. from there you should be able to get some heavy duty stuff easy enough if needs be.

AHA!!!! That what i wanted to know! i'm running this toyota 5-speed in question behind my A14 turbo and i wanted to know if the toyota plate that is supplied by dellow will be able to handle boost?

What alternatives are out there? what has other people used?

EDIT: thanks Pepper, i'll have to make some inquiries!

If your running serious boost (20 psi+) the standard (dellow) clutch plate will fail prettymuch str8 away i`v had to shorten my clutch fork to get more purchases on the p-plate but it still slips at 15 psi+ ( 80kph in third).
What sort of set-up are you running ( EFI, DRAW THRU,?????)

Blow through set up, running through a 350 Holley, it's running 15psi at the moment. Pic is in my album.

Rang up the local brake and clutch place today and i found that there is so many options available! i ordered a extra heavy duty unit from a celica(early model i assume) should be able to handle boost! i hope!

sure your getting the right thing steveo?

with the conversion you still use an a-series flywheel and a-series pressure plate... and the clutch plate is the a-series heavy duty one with the centre splined changed to the celica spline

so essential it's still all a-series bits... if you ordered a celica pressure plate it's not going to suit an a-series flywheel

i have a ceramic button clutch to suit a-series, i think it cost the original owner 270 (maybe it was 370)

i'm not a fan of the button clutch though as you lose control in regards to slipping the clutch in and out, particularily handy in a rally car, but it was a pian on the street too i had it for a year or more and still stalled the car every now and then trying to pull away from the lights casually

The stock A series diameter plate is just too small for a strong boosted motor. IMHO, I wouldn't bother with anything of the 180mm variety. Take your flywheel to an engineer, and get them to re machine your flywheel to accept a 200mm P/plate. Then get a toyota center fitted to a 200mm friction plate. I used a (Heavy duty) 200mm L series P/plate on my A series. They only just fit on the flywheel though.
In the very beginning, I ran a (MINT) 180mm plate behind my A14 S/C. And it couldn't keep up. The extra money you'd spend trying to make a 180mm clutch heavy duty enough would be waaaaay better spent on getting the greater surface area that goes with the 200mm plate. It has around 36% more surface area.
