Anyone think a 5th gen clutch and pressure plate would hold a 3.5 swap (Tilley's way) with nothing but a Cattman full exhaust and JWT ECU w/ 8k rpm redline? Would a Fidanza flywheel make things easier?

Sorry if this is a repost... My search on this wasn't exhaustive but I haven't found anything conclusive.

 

Bump.... Anyone?

 

No, I think it would start slipping. Get an ACT Heavy Duty...i think they sell one that holds up to 336ft/lbs TQ. Ask Krismax, he has a very similar setup.

 

I forgot to add that the car would probably never see the track. I'm looking at it strictly as a daily driver.

Does that change things?

 

I would get an aftermarket upgrade just to be safe.

 

yeah yeah...aftermarket for sure...they say the 00-01 clutches are stronger than the 95-99...dunno to what extent....but having driven both cars (3.0 and 3.5)...the torque difference is HUGE between both cars....i doubt a 3.0L clutch can handle the 3.5L tq

 

Fair enough. But I won't have VTCs or an operational VI, and therefore less power than a 5.5gen, especially on the low end -- which is fine by me, because if the one VQ35 4th gen I drove is any indication, it'd be a little twitchy without e-gas and a 30-pound flywheel anyway.

I'm probably looking at about 210-220whp. That's, what... 30-40 more than a 5th gen? And on top of that, the 4th gen is lighter overall, I have lighter wheels/tires than most 5th gens (~40 lbs per corner), and I would most likely be using a lighter flywheel as well. That's why I'm thinking it could work.

Am I wrong?

 

not to go off subject, but why would your VI be non operational?

 

When I was talking to Tilley about it almost a year ago, the car he showed me as an example just had the VI set wide open. IIRC he felt it was too much trouble to hook up. I got to drive that car a few months ago and, honestly, I didn't find it lacking for power (it was his 13-sec all-motor car). I realize now that people have made the VI work, but I thought about it and I really don't think I need the extra low-end. It'd still be a ton more than I have now, and given the crazy response that the engine will have from the cable throttle and flywheel, low-end loss doesn't really sound bad, especially if it means I can still use my buttery-smooth 5th gen clutch.

Besides, ~210 whp is already starting to push it with 225-section street tires, and I'd rather not go any wider because from what I've seen, good tires in 235 and 245 widths tend to be significantly heavier and more expensive.

So... that's the rationale.

 

How many clutches have you gone through ? If you can get up to 100K miles out of a clutch, 3.0L OEM clutch will have no problem with holding down all them "210WHPs". It all depends on how you drive, personally I would stay awap from ACT clutches, I haven't had one that lasted more than 30K miles. And I have 70K on my Exedy Stage 1 without any hint of slipping or failing, and I have a bit more than 210WHP but lack bout 10lbs of TQ of a 3.5L 4th gen setup.

Get a EXEDY clutch- SPEC, ACT are ALL garbage.

 

I went through an Exedy OEM replacement clutch from eBay in about 35k miles... but that was with some really, really stupid behavior early on. Needless to say, that behavior has long since stopped. It's too soon to tell how my current habits are working, but I really don't think I'd have trouble getting those 100k miles out of a clutch. Most of my driving is highway, and I try to keep my shifts as quick as possible.

 

word on the street is that a stock 3.5 clutch setup holds 400ftlbs...not sure why you would want to go for a lower grade clutch

 

i dont think u can use the that 3.5L clutch...doodfood is swapping a 3.5L into his 4th gen but using 4th gen components such as the transmission, timing covers, ecu....so he cannot use the 3.5L clutch....only 3.0L clutches are available since hes using the stock 5spd tranny

 

someone said something a while ago about usin a 5th gen clutch in a 4th gen, i guess they could have mean the 3.0 5th gen i guess though. well if thats true then ya, definitely dont go for the 3.0 clutch, get something with more clamping power

 

I went through the same clutch on my 3.5 in about 2 weeks
