Hi guys and gals,

Clutch is slipping at high revs, therefore examining all the different issues that may be causing it. It is in having the clutch adjusted as I couldn't be bothered doing it myself. This may solve it but if it doesn't are people using Exedy exclusively or have they found other heavy duty clutch kits the Starlet GT? Also got a bonus from work so aftermarket ECU here we come.

Cheers

I started with the Exedy heavy duty before i blew the motor, when i pulled the box off to fit the lsd it wasn't looking crash hot after only being dyno tuned.

I got a custom clutch made at a local mob in Sydney who are well renowned for their work.

I told them how much power i wanted it to hold and they made one to suit, recommended a ceramic button. It's very heavy, and it bites - but i'd rather that than to have to replace the clutch anytime soon.

Ooh, that's interesting, as I have an Exedy for mine, and so does JC and Tony!

I'd rather replace the clutch than the gear box. Mind you it would probably be the driveshafts or cv's that is the next weakest point, and at least thats not an engine out job.

Just remember when you upgrade the clutch to a very heavy duty bitey clutch, you are effectively moving the weakest point down the drive line. Make sure its not to something thats too expensive like a custom driveshaft.

On the other hand it sounds like a few people have had trouble with Exedy clutches not lasting.

I think the Exedy is ok - but it will not have a very long life with big power and it wont stand up to dragstrip like abuse.

Look on austarlet, a few guys have burned them out. They are only rated for 20% increase over stock..that's 160HP at the motor which is say 140atw at best.

I would much rather stuff around with CV's, driveshafts etc than to be pulling a motor out and box off. You might rather replace the clutch than the gearbox, but the gearbox still has to come off to replace the clutch - so cost wise yes..as far as the work involved..no way, i'll stick to driveshafts

The box is pretty strong...touch wood.

Worst comes to worst - get cheaper tyres

Bugger! We'll see how it goes in the starlet then......

Agree - may be due to mode of operation!

Yeah Extreme was the response on Austarlet. So I think that may be the way I go. One other issue may have been that I did not adjust the clutch actuator and so full engagement never occurred except when brand new and so basically burnt the clutch out earlier but I think it simply went. The tires have lasted me only 5 months but were DO1J's. Oh well engine out then, bugger....Still with a new clutch, new rad and a microtech LT10 she should be sorted...

I'd look at getting something made to spec rather than off the shelf. Tell them how much power your making and you'll get something made to suit. Mine only cost $440 for the whole pressure plate and 4puk clutch. It'll also be closer and if there are any issues you can take it back.







Dan has a great cushioned button clutch as well.

Have you looked at Adaptronic Matt? For the money they can't be beat, really good locally developed ECU. I'm not a huge fan of Microtech's - Dean has never gotten his to run right, Starting is an issue and cold starts are even worse.

It'll be awesome once you sort out fueling and clutch

Thanks for the heads up Josh about the Microtech, my only reason for going the Microtech is that there are a number of places that will do a walk in walk out fixed price installation including full dynoing.

Yeah I don't want to have to replace this clutch again any time soon so I think I will go something like this. Yeah I looked at a Adaptronic which was my other choice, given your statements I might go that way especially as I know they have previously done a 4EFTE... And yes it should go like bullet after the engine mangement and clutch is sorted...

By the way my pedal is pretty firm will something like this make it extra hard?

Cheers

Microtech's are very common and almost all workshops will tune them, but most people will tell you they are not that good. They are cheap and will make good outright power, but off idle running and starts just aren't refined. Borgy on here runs a Microtech as well and he doesn't like it. I've never used the adaptronic, but have heard good things and the developer Andy is local and will help you out with any requests or changes that you may want with the firmware.

Do you want to stay in Canberra to do the ECU? or would you come up to Syd?

Comparing my pedal now to what it was with the Exedy it's a bit harder, but i wouldn't say too much - it's personal opinion though, I actually like a tough clutch with some bite nothing worse than a slippy clutch, then again it's not a daily driver anymore and if it was it would probably crap me. Just about everyone who has touched the clutch has gone "WTF!"
