4 AZE 4 AGE

[sherv]

does anyone know if a supercharger from a 4 aze engine will fit a a age? what else would need to be done for this to work??

no you cant just bolt it on, the 4AGZE runs a much lower compression ration and all the inlet side of it is different, ECU also different as the supercharger itself has a clutch and only comes on when you have open throttle. Easier to use a low compression turbo on the 4AGE making it a 4AGTE.

wow, sounds like you really know what you talking about! thanks for the reply ill have a look into that route rather, unfortunately i have to wait till november to carry on my build as im in Germany for a year,

out of interest what else would you need to run this set up on a budget? apart from the standard 4age engine, my engine, is from 1989 corrolla, with the red lettering i believe it to be a the third-generation of this engine. the compression ratios are 9.4:1 to 10.3:1 with smaller cross section inlet ports compared to previous models. Hopefully the correct one, for this conversion but im not sure,

anyways fabrication of the car/frames are easy, but im new to engine modification, any help will be much apriciated!! :D :D

sherv you can get the 4AGZE pistons new from the states very cheaply and thats the only internal difference as its these that lower thr CR so set of those and then the SC route becomes much easier.

It sounds like you've got a late model smallport 4A, so like Sam says, the only difference between your model engine and the GZE is the low comp pistons.

IIRC, your model engine and the late model smallport GZE share the same internals except the pistons...

another option would be to use the GZE pistons and use a low compression turbo and that would see an easy 175bhp or go higher boost for 200+. I have a HKS "uppy" cast T3 manifold and a compelte T28 turbo setup on "downy" manifold that is going to be used for twincharging the 4AGZE in the MR2 which then makes it a 4AGZTE engine (z denotes supercharger and T for turbo). Turbo would take up less space and if u went low boost route you could possibly also keep it high compression engine as better fuel economy and better power but very tricky to build this and keep it reliable but not impossible.
