Blacktop Flywheel on 4afe/7afe

[jeremiahnz]

Can anyone (preferably with some engineering knowledge) tell me if there is anyway to have a blacktop flywheel safely modified to fit a FE series engine? The FE series only has 6 bolts rather then 8.

Cheers

nope, unless you are planing to change crankshafts (to make it 8 bolt)....

[Jebus]

nope again, if you just want lighter could go for something like this (to the dismay of everybody anti lightening flywheels, search to find out the risks)

as 4AFE/7AFE/4AC are all the same IIRC and 1ZZFE may also be??

[jeremiahnz]

Yeah, I've seen that trademe one.

I was hoping that there may be some way to redrill a blacktop flywheel without sacrificing the integrity too much.

MS Paint says No.

Haha, cheers for that.

Hmmmm, when I done my silvertop conversion I had to use my flywheel from my 4afe. Two of the bolts matched up.

As my dad is a fitter and turner, we cut little bits of bolt, threaded them into the unused holes, welded them up, used a milling machine to drill and tap the new holes, and finally put the flywheel on a lathe to see if everything looked good and smooth everything out.

I had the flywheel on for about 20,000 kms and nothing went wrong. Only reason Ive put a proper one on was because I changed my clutch and had the oppurtunity to, and the "fe" one was a bit heavier.

While on topic, what have people used in their 7AGTEs? I'm assuming standard crank and the 7A flywheel?

Thanks for that. That was a similar idea to what I was thinking. Can anyone provide further opinions on whether they'd consider this to be safe?

I don't believe there's any reason why this should be a problem. Just be sure to use the right people.

[jeremiahnz]

Would it be fine with the standard 4afe clutch?

[20v_rollaboy]

The clutch will fit. Depends in what condition it is in as to how long it will last. I would change it just because you have the gearbox off and wont have to do it again down the track.
