ive heard of a 7 age whats is this where did it come from? I'm guessing rare in Oz? what are the specs and such? are they they worth finding and buying?

A 7AGE is a hybrid (as in bits of differente engines, not petrol-electric :P) engine with the block of a 7AFE ad the head from a 4AGE. They aren't a factory engine, and as such you won't "find" them in anything in particular, and they are as rare as any other hybrid engine (maybe a bit more common though).

 

Don't bother trying to find one, just make one yourself, there are plenty of threads around detailing what they are and how to build them.

what sort of advantages are there? is it only 7 afe block and bottom end used then the rest is 4 age?

you get a 1.8L 4age.

 

head over to ae86dc, there is a large tech article/discussion on making one.

 

or even just have a google.

 

i wouldnt do it myself, but some people have had success and swear by the idea.

has any one here got one? or had personnal experience with one to say whether its worth it or not

Matt's 20V ate one for lunch, they don't make much extra power than a 4AGE, just more bottom end torque. They need aftermarket rods if you plan to rev them hard, so it isn't a cheap or common option.

lets say i have a crazy idea of building a 7 agte. with beefed internals and major head work just because i hate having tyres. iv got 12g to spend with the refurb of the car 5 g to body and paint so still a bit spare change left over for a bit of engine work.

If you have 12g then just do a 4agte or an SR20det, the let down with most 7age's is that people use small port heads, I have seen 7age's make from 90hp up to 180hp, to build one quickly you just stick 4age pistons in the 7a block (valve cuts), bolt the 4age head on and use a porsche 994 (I think) timing belt.

Or if you have that much........3SGE or 3SGTE

The weight is a let down.

Really what's the weight difference of a 4age/7age to a 3sge (oh and i meant the beams version)

ive got a bigport 4age in it now so i will use those parts

What are you rebuilding? a micromachine?

Not all paint jobs are expensive you know, the expensive part is body work, painting is cheap.

<snipe> porsche 994 (I think) timing belt.

Porsche 924/944

 

HKS 5age ??
