Supercharged 20v

[gemless]

i have done searchs but found little information.

 

mt plane is to buy a 20v and put the low compression pistons out of a 4agze in and strap on the standard 4agze supercharger.at the moment i have a ae82 4age and a 100kw lift back.

 

id like to know if anyone else has built a supercharged 20v?

will the 4agze pistons fit into a 20v?

will i be able to use the 4agze gear box on the 20v?or would the 6speed box be better?

what was changed on the second version of the 4agze to give it 20hp more?higher compression?

 

thanks brett

Later model 4agze run:

-Higher compression 8.9:1 not 8.0:1

-runs 10psi not 8

-smallport not bigport

you'd be better running a sc14 off the 1ggze.

You would have to change your induction to the GZE intake as running ITB's would be hard with the charger mounted where it goes, After the questions you have asked i think you are going to be better off buying a smallport GZE halfcut and doing a full swap over and change the S/C pulley and doing the ABV (air bypass valve) mod, That way you will have more power than the 20v did.

Seen it done, but ran out of power after about 6000, as i just can't supply the volume of air the engine needs, in the end made the car slower, Just go with a 4agze to begin with

AE70-thanks for the info0 much appreciated

 

POZMAN-why the sc14?more air?better mounting location?btw thanks for info

 

Trev-could you please explain the air bypass valve mod.when you say power do you mean torque, kw or both?would using the sc14 give a better postition as i plan to run it with the ITB's.thanks for the info

 

NickZ-would using ITB's, the big port 4agze head,higher psi and a sc14 give power above 6000 rpm?thanks for info

 

thanks for the info it has helpd

SC14 has a displacment of 1.4L and the sc12 has a displacment of 1.2L. SC14 pumps more air due its size.

what he said, 20 rev harder so they flow more, also it's a good mod for a 4agze, so kill two birds one stone

The ABV mod utilises a plate to block off the air bypass valve so you get more of an accurate boost instead of it bleeding off, You will get more HP and torque.
