No offense to you guys interested in a 4A swap, whether its a GE or GZE....i cant see justifying it, and this is from personal experience in having driven with a 4AGZE before. If i had an ST, i would sooner get a turbo set-up and have it all done professionally someplace before swapping out the 7A for a 4A.

I mean, sure...the 4A is a more "performance engine" in its purpose, but the power and cost advntages just arent there in light of the effort involved to make it work. For the ammount of money put into a swap, you could have a 7AFE engine cranking out some pretty reliable and impressive power. It also allows for more displacement than a 4A could provide and to me sounds better running than a 1.6 liter does.

When i drove the MKI MR2 with a 4AGZE, i wasnt all that impressed with the output, even in a lighter vehicle like the MR2. I mean, it had some great response to it when you nailed the throttle even in 5th gear, but i dont think its worth the money and headache to swap it in when theres a boost-stable platform under the hood already.
My opinion is that its simpler just to tune a 7A well to around 160-170 with a turbo than to swap in another engine. Feel free to disagree with me, but i get the feeling that theres alot of hype attached to saying you have a 4AGZE when its not terribly fast and theres easier alternatives.

this seems to be pretty un-informed..... it also depends on what he wants to use the car for..... if it's like auto-x and road course i say go naturally aspirated, makes for smoother and easier driving and maneuverability..... if you wan't just straight line power then do a turbo setup

but you really can't justify building a 7a-fe to a 4a-ge... the 4a-ge head and blocks are both stronger (unless you outfit the 7a-fe with a 4a-ge head and internal 4a-ge parts... but then you still have a weaker 7a-fe crank)

like you can see above, i spent a total of $1600 on my 4a-fe to 4a-ge swap.... which includes several aftermarket parts...... a turbo setup done by a SHOP will cost you around 2 times that amount for mild boost (and if you're paying less than that by a lot, then i wouldn't trust the work... just my opinion... you get into tricking the ecu, running boost, and driving the engine harder you should spend the money)...... and at that point, you have a peaky HP motor that's generating a LOT more heat and is working a lot harder.....

if you build a 7a-fe to stay n/a be prepared to spend a fortune trying to get good numbers.... racer25 on corolla-racing.com (although has done ALL of his own work) has done TONS of work (i believe including a port & polish head, rebuilt block, 4a-fe higher compression pistons, tuned ecu, auto->5sp swap, intake, headers, exhaust, and i know theres more) and he has lower HP numbers than my 4a-ge and just mildly higher torque numbers than my 4a-ge..... he has spent more on modifying his 7a-fe than i have on my swap.... and i haven't started doing much to it at all and have a stronger platform to work off of

that's just my opinion....
