7afe v& 4agze

[corolla-18's]

what can a 7afe use from the 4agze engine wise, if anything?

[jon_570]

nothing...the 4agze has diff cams and pistons because of the s/c plus the gze is a 1.6l and the 7afe is a 1.8...so intake no..pistons no cams prolly not...why what are you trying to do?

[REN69]

You can't use just single parts from the GZE onto the 7AFE, HOWEVER there is something called a 7AGZE hybrid, where you would keep ONLY the 7AFE block and use the 4AGZE head and internals, wiring, etc...... it's basically a 4AGZE with a 7AFE block. Expensive but it puts down nice power figures.

^you would use the pistons from the 4A-GZE, but crank, connecting rods from the 7A-FE, atleast so I understood from the whole thing.

nope.... that's where it gets tricky, as the compression would be WAY low

[freakinbox]

didn't think high compression was as much of a worry with a FI engine like it is with an N/A engine

no, its only low if you use the dished 7afe pistons.

im trying to get decent power to the ground in the N/A way, i want internales, like cam gears, camshaft, pistons, rods, you know. i got an auto and i dont have the money for an auto swap, but i want some power, what about P&P, bout how much will that and boring .20 over give me, pulleys if anybody knows?

[corolla-18's]

and i seen a kit on horsepowerfreaks.com that makes your intake manifold bolt up to a b16, b18, or h22 intake, would that actually work?

[freakinbox]

if you want N/A the 4agze stuff isn't what you want. If you don't have enough for an auto to manual swap not sure why your looking at an engine swap

[corolla-18's]

well i got a complete 7afe on my porch, waiting to be rebuilt so i just wanted to be the lil sleeper car round town were honda rome the streets, so if i have an auto with a lil power they will never see it coming and what kinda ecu can i use, like standalone, what about jet, who reprograms your chip they say, or what about megasqirter, how hard is that to hook up

[freakinbox]

yea but still, why use the 4agze for parts if your not going to stay supercharged or go turbo? you could use a regular 4age big port or small port from an ae92 instead... or use a 20v instead 7age 20v :o

[Piloter]

Best NA potential: 20V head on the 7A.
Cheapest swap: 16V bigport head on the 7A.
Easiest cheapest route to power: 16V GZE head on the 7A. Swap SC for turbo, keep the boost down.

Probably the best budget option for power out of something with a 7AFE is to either turbo the 7AFE straight-up or swap it entirely for a 4AGZE.

[freakinbox]

problem with the f/i options is that with that type of power the auto tranny won't last long, unless you get an auto that was meant for the 4agze, I know the mr2's had it but the ae92 probably didn't... gts only came 5 speed so I doubt the option of a 4agze for it came with an auto.

[Piloter]

Don't talk to me about auto tranny issues with the 7AGE. Forgot that part. Yeah, the A241E transmission bolted up to the 4AGZE on the SC MR2 and was designed to hold ~165 horses. Had an LSD, too, and the same gear ratios as the A245E that came with the auto 7AFE applications. Same four solenoids for shifting.

As to whether the connectors and such plug in...

And whether the 7AFE ECU (OBD-2) can control it (OBD-1 unit)...

And the likely need for custom axles...

NO IDEA! These are all issues I have yet to work out for my own project Real Soon Now.
