You sure about the 3-rib block? All GZEs were based off the 7-rib block

And there are only 2 bigport GZEs anyway (distributor = AW11, coil-pack = early AE92), and neither had TVIS either. I'm guessing you've got a bitsa motor

as above

tvis = not gze.

3 rib = BIG not a gze

 

Some one has strapped a charger to an old block.

 

If you pull it down you will know.

Ok so i think i may have made a mistake......

 

pleases tell me that there is 7 ribs there......

 

and yeah its got tvis? whats the go there? I'm going to get a custom plenum made anyway but still

 

P.s no charger, going turbo.

AAHHH ok I’m starting to freak out here, as i said in my original post: I have been reading thing and they all just don’t add up.....

 

Well I found this site that was talking about the TVIS bizzo and I realised that I only have 1 large throttle body (butterfly) at the front o my intake plenum.....

 

Now is this supposed to be in the yellow circle?

 

I got it from the wreckers the other day when I went to get a wiring harness I just couldn’t be bothered taking it off the harness.

Thats were tvis goes. Bin it imo. Thats a 7 rib, and thats not a gze intake, but thats ok there bad any way.

The GZE intakes are bad or the big port intake is bad?

 

so chuck it you rekn? I'm going to get an intake plenum made anyway.

 

thanks everyone :)

 

but I'm still stuck wndering what GZE i have

yea thats a 7 rib block, and you got a knock sensor so its should be 4agze, unless someones put a bigport head on a smallport block (very possible as you got a NA 4age alternator mount on it)

 

looks like some one bolted on the tvis and NA manifold on

 

if your going to turbo chuck the tvis in the bin :)

yeah when i pulled it appart to get it out the car, the tvis was bolted to the mani/gasket then to the block as is now in the pic, no tvis

 

So i think the prev owner was just using it as an intake plenum?

 

wow ok this is difrnt

yea a 4agze has a different intake manifold, as the throttle bodie is before the supercharge so not on the intake manifold.

 

if he was using it for turbo, he would of put the rwd 4age NA intake manifold and the NA 4age alternator bracket on it

 

edit just noticed it doesnt have a 4agze cooling system too hmm did he say changed all this stuff over?

Edited June 24, 200917 yr by Roo

could it be a 100kw??

 

big port head is better for turbos i think, you don't want a tighter space to force the air in,

 

do a compression test, my good gze bigport put out about 138-140psi

 

take the head off and look at the pistons they should look like this

 

 

 

should a ciramic coating, deep dish with flycuts for the valves

 

 

 

its like holding a baby

Edited June 24, 200917 yr by ae174agze

yeah i was going to take the head off but i would rather not have to re shim the head.

 

yeah going to do a compression test soon, just got to buy one irst

if your going to turbo chuck the tvis in the bin :wink:

This is what some people do because you can only get to a certain power level with the small-port head, but the big-port can get to insnae levels of power N/A. I have seen some with 300BHP+ going N/A. I don't know where I saw it, but it can be done.
