hey all, just picked up a 4agze for nice and cheap!

 

I'm going to turbo it but first i need to replace the rings and main bearings.

 

i have an n/a 16v 4age now

 

I'm wondering can i put the na head on the gze block? also can i use the same loom

 

silly questions but I'm wanting the best advice at the right price ;)

 

cheers-Luke

Hey Luke, the heads are fine to swap, as long as they are the same (big/small port) although the camshafts had different lift and duration, does the gze loom have any extra sensors over the 4age? I can't remember.

Club4ag.com has alot of useful specs on the 4a series.

The 4AGZE loom is different to that of the 4AGE, so is the ECU.

Depends how you are going to setup the GZE when it is turbo and are you going bigport to bigport?

Hey guys , I don't actually have the gze loom so I wouldn't know. I was hoping to use just the big port head on the gze block and go from there. Would you know if I can just straight swap the cams or would I be opening a can of worms. As far as the ecu goes I was talking to Sam from razorback he can do me one for 350

Why are you swapping heads?

I still have no idea what you are trying to achieve.

 

What is wrong with the gze head?

It is probably a smallport GZE and he would prefer a bigport.

yes bigger ports :) also I'm trying to be cheap and use the rwd intake i allready have would that work?

Yes, so you wanna use the smallport CAS and coil setup?

I'm guessing the gze i got is an earlier one its a smallport gze with a dizzy, as far as I'm aware i haf to get a dizzy relocation kit and run coils but i don't know what a cas is haha i sound so new but ive never dealt with a smallport or gze before

The early dizzy 4AGZEs were all bigport, the later bigports and all the smallport ones were DLI/CAS (Distributor-Less Ignition/Crank Angle Sensor).

 

I think you should double-check exactly what you have now before you go start buying things that may be worse than what you already have, or even exactly the same....

its a smallport head with a dizzy hole, its a 7 rib block i don't think it has a CAS il check when i get home and upload som snaps!

*sorry, meant "cam angle sensor" (the definition varies depending on which engine you talk about, but they do the same job), on the GZEs it goes in the same place as the distributor would.
