How Hard Is It To Supercharge The 4age?

[MISS SX]

Just want to know, is it hard to charge the 4AGE or is it just easier and cheaper to buy the 4AGZE??

 

i want my super charger and i want it now

As far as I know all FWD 4AGE's that came in Australia are MAP sensor. Only the MR2 ones are AFM.

yup, some markets got afm but i think only USA. not sure...

 

 

easy to turn 4age into 4agze, but $$ will be the problem, maybe cheape rand easier to turbo though

[1G-GTE KE70]

4A-GZE pistons and thicker metal head gasket to lower compression.

[Mr Revhead[RL]]

no the4agze pistons are lower compression.

4age/4agze headgasket is the same

It would be far cheaper and WAY easier to just buy a 4AGZE (about $950). At this price you'll still need to buy a computer & ancilliaries, or you could just buy an AE92 or AE101 4AGZE half-cut (not sure of price).

[ancullen]

Correction. AE101 4AGZE $1,200. Halfcuts available from about $2850. Couldn't find a price for any engine packs (engine with ECU & ancilliaries).

Thanks Guys for your input..... Money is but isnt a prob, cause my uncle can get me the engine really chepa and parts, just needed some extra info...

 

Cheers :P

HEY DUDE NICE ROLLA !

 

I FOUND SOME GOOD WEB SITES THAT MIGHT HELP U.

THEY HAVE HELPED ME WITH ENGINE CHOICE FOR MY ROLLA.

GOOD LUCK !!!

hey done some more lookng into this....

 

you can slap the s/c gear on to an n/a 4age no worries....

id go for the bigport though. the aw11 I'm buying has an n/a blutop thats had ae92 gtz s/c and ecu put on it, faster than 4agze casue of the extra compression :D

[Mr Revhead[RL]]

not sure how tough the 3sge is... its all in the tuning though!

So it's running 9.4:1 compression and 10psi boost? You've just captured my interest. Has it been setup that way for long??? The bigport head would also be an advantage. It's pretty much all my engine's missing (I've got AE101-spec 4AGZE). Either a bigport 16 valve or a 20 valve, that is :)

[ancullen]

Just on the topic, I plan on putting some pretty wild cams in my motor (much later down the track when I suddenly become rich :dry: ). I'm thinking 304 intake and 288 exhaust with a bigport head. I'd take the redline out to 9000rpm, meaning that the supercharger would start making 15psi boost, but I was going to leave the compression ratio stock (8.9:1). Does anyone have any idea if this would work, or would the comp. ratio be too low for me to be able to get the engine to get up to those rpm?

[Super Jamie]

apparently you can wind 8psi into a stock 4age with minimal side effects

 

those are pretty big cams, and that's alot of boost. not being used to working such numbers out, i'd suggest you get proper cam timing specs (304/288 can be ALOT of cams) and calculate the dynamic compression you'll get by combining that static compression, those cams, and that boost

 

calculate DC for a stock motor, for modified motors that you know hold together, and for your plans. if yours has way more DC than the ones that work, then likely you're in trouble

 

i couldn't really tell you an ideal DC for a 4age, those new fangled overengineered twincam crossflow things break all the rules. a long time ago you used to have to be super-careful (everything balanced within 0.5g, blueprinted, etc) running over 8.4, but a honda D series motor runs 9 stock!!!
