4ac Modds....

[luke641]

Hi guys im new here so take it easy on this question....

I heard that you can put a 4age head on a 4ac and it will increase the power of somthing rather.. I havnt heard of it befor this guy told me so im not sure its true...

So yer...

dont waste your time

[luke641]

Im not saying i would do it...

Just want to see it is true?

[shift_rook]

you can, it'll give you a comp ratio of around 6:1so it'd be shit, try searchin first dude

I don't know why this rumour is still out there, its the most stupid thing ever.

You have to go to the same level of trouble to put the head on the 4AC than what it would be to just put in a complete 4AGE if not even more.

Except the main advantage of putting a 4AGE head on a 4AC is that you get to waste a lot of time and end up with an absolute turd of a motor!

[Axentrik]

so the blocks are the same, with different internals?

[Golberg]

I'm reasonably sure that if you stripped it down to the bare block you'd find that a 4AC block is the same as a 1st gen big port(blue top).

I've been thinking of doing it on my very clean AE71, basically keeping the 4AC block (which has the original engine no. on it corresponding to the build plate) and basically stripping a 4AGE and swapping the 4AGE internals into the 4AC block.

does anyony once know the volumes of the 4ac? piston dome & combustion chamber?
the 4ac supposed factory compression ratio of 9.0:1?
i highly doubt it would be 6:1 with a 4ag head.
on the topic, does anyone know if the 4ac crank timing belt pulley is the same as a 16v 4age?

4age's are 1000 bucks save your money and buy one.

[sun_moon]

no compression and also piss weak internals.... not cool.

a stock bigport 4age are slow enough, so imagine one with 6:1 compression LOL !!
