Any help would be appreciated (i hate to see it just sitting on the driveway)

Cheers

Well that's the thing, i believe that the standard supra clutch can handle up to 500bhp

Yeah soon i want to get a single turbo, but not just yet

I honestly can't say until I know your max rwhp goal.

i would say im looking to make it around 500 hp

Again, there's absolutely no way in the world to confirm this without knowing your planned max rwhp.

Why do you say that? The oem fuel pump, and in fact the entire oem fuel system is good to at least 500rwhp....and the oem twins can't push that much rwhp so why would you need a new fuel pump???? :dunno:

This is what i was told by the guy who was going to do my exhaust fitting etc.. i was a bit like errr why as well, as i didn't see why i needed to change the pump for just the exhaust!

Every multi-disk clutch, including the TRD twin, comes with it's own lightweight flywheel.

Unfortunately, no good, high-horsepower-holding aftermarket clutch will be cheap. ...and the higher the hp/tq rating, the more $ it will generally cost. For example the RPS twin carbon is about $2900 and the Tilton triple carbon is about $4500. It's easy to buy more clutch than you need, so the first thing you need to do is figure out exactly what rwhp figure you need the clutch to handle.

I can advise you as to exactly what would be best for your application, but I need to know a bit more about what you plan to use it for in order to give you the best advice. Please answer these questions:

1. Again, what "engine work" are you planning? A single turbo?
2. What is your application? Roadrace? Autocross? Drag Race? Drifting? Daily driving? Hill Climb (eg. Pike's Peak)? Top speed (200mph+)? etc.
3. The other question I posted above isn't clutch related, but I'm very curious: Please tell me why you say "im am looking to change my whole exhaust system taking out both CATs and will therefore have to upgrade my fuel pump"?

The reason i said i would have to change my fuel was coz the guy who was doing my modification advised me that i may have to upgrade my fuel pump, as i was taking out both CAT's... i was unsure as to why this was necessary as well!

I have to advise you to stop using that guy as an installer because he's dead wrong. Sorry to be so blunt about it, but there's really no other way to say it. The oem fuel pump is good for over 500rwhp (through a 6spd), and absolutely anything the oem twin turbos can push out. I'd literally LOVE the opportunity to 'educate' your installer.

Agreed, but why are you limiting yourself to twin-plate clutches? There are several aftermarket single disk clutches that can hold your target rwhp... Only downside is slightly higher/harder pedal pressure. Would that be okay with you?
