20v and 16v 4age flywheel interchange solved, how bout in/ex manifolds?

[Wildsupra]

will the 20v black top and 16v 4a-ge flywheels bolt on to each other or do 20v have a different flywheel bolt pattern?

[damo101]

should do..both are 8 bolt flywheels

[psychofox]

100% interchangeable - with some caveats. The early 16V, ie AE82, some AW11, AE86 engines suit a 200mm clutch. Smallport AE92, some AW11, all the 20V suit a 212mm clutch. All are 8 bolt. Blacktop AE111 flywheels are lighter as well.

yeah i can gaurantee the above i have used the blacktop flywheel in a aw11

[Wildsupra]

ok cool, my plan was to replace an aw11 4a-ge with a 20v blacktop and use the original flywheel and clutch setup from the 16v 4a-ge on the 20v. Reason being is that the 16v engine has not long had a new clutch on it, so why waste it ay.

Anyone know how interchangable the inlet and exhaust manifolds are? I believe the exhaust needs one hole redrilling or elongating?? How bout the inlets?

Not that i neccessarily need to change the manifolds for any reason, but if buying aftermarket gear would be nice to know some options.

Inlets are completely different, the exhuast is close, but you need to slot the outer two holes in the manifold.

Here is a set of extractors with a 20v flange and a modified 16v gasket:

i guess i'l stick to the right manifolds then
