swap a 4a, be prepared for disappointment.
you wont say it, cause you'll wanna cover your own a$$ in the end, but first time you ride in a 3s swapped 6gc, or even a beams swap, you'll wish you'd not spent your money on the 4a.

So basically the 4age is just a waste of money?

Not if you HAVE to rebuild your 7afe...I mean yes it wouldnt compare to a 3sg(t)e swap. But it is a crap load cheap and easier for us ST guys, plus you wont get get 20mpg premium like all the 3sgte swaps

if your looking for an N/A motor to build and keep N/A, and want somewhere close to the 200hp mark, i would highly suggest the beams swap. It's probably one of the easiest, best bang for your buck N/A engines that you can swap into the celica.

If you want something very close to N/A power but not turboed, the 4AGZE is another great choice. I remember someone posted a link to ebay where someone had swaped a 4agze into a 6th gen, and weither the numbers were correct or not, i remember it was somewhere around 180, which is respectable.

Im in need of a rebuild, but i also need to look at putting new timing system, water pump, thermostat, ignition, wires, velocity stacks, possibly webcams, and a few other odds and ends on the 4a if and when i do get it so i have to look at that also

Webcams isn't going to get you cams for a 20V.

HKS (~$1000 for a pair), or Toda (good luck), or nothing.

Kyle do you plan to swap the tranny as well?Or keep your c52?Because if your gonna tranny swap id def go beams.

Wrong.

Peak torque starts at 6 yes, peak horsepower no.

the AE101 Levin redlines 500 or 600 short of 8000, the AE111 Levin redlines right on 8000, both motors make their peak horsepower right on the redline as do other 4 cyl GE engined cars of it's time such as the SS-II and SS-III Celicas.

If you're dropping off after 6k rpm it may have something to do with the bt ecu and silvertop setup you had.

The 4a is a good motor I would take a 16V 4AGE over a 7afe any day, yes the 4a makes more power up top but they are
not the puny little wimp for low end. I have thought about swapping my 7a with the 140 hp16V 4AGE I have sitting in my garage.
I haven't because I really want a 3rd gen 3s. I would think about what you really want, for a basic commuter engine, the 4a is a
helluva lot more fun than a 7a to drive. The main problem is, even if you spend a ton of money to build the engine, turbo, ect, it is
still going to be less power than a stock 3rd gen 3s, with nowhere to go after that.

If I remember correct, Coomer put a 7A geared tranny in the yelli celi, so it is going probably seem different than a 4A geared tranny,
as far as low end.

It wouldn't be that much more difficult to swap a BEAMS into an ST. Just need a few little things. But the issue that I see is cost. The 20V can be had for a lot less than a BEAMS. It seems like in all the posts I've read, the 4A will actually cost you power on the low end over the 7A. The 7A will pull harder from a stop. But as far as options go, you have the 7A-FTE, which will mean a full rebuild of your engine plus all the added items for the turbo build. Then you have the 4A series engines, the 4A-GZE being the best, of course. But I don't really see how you can go wrong with a Silvertop over the 7A. Yes, you may have to rev it hard to get any power, but you have to do that with an S2000 as well, and people never complain about that. Besides, quite frankly, you have to rev the 7A as hard as you can and it never rewards you with more power like the 4A-GE will.

There are pros and cons to the swap, obviously. Cons being less low end power, pros are more top end power and cost/ease to swap as opposed to the 3S's you could get.

4A Swaps sound cool and all, but really, what are the gains? spend all that money for not much gain, in the long run youll be dissapointed, might as well go trade your st for a GT, and there u go. Swapped.

No heading u for a beams swap, but why not a V6. they are becoming more popular if u dont want to hassle with a turbo.

heck, dont the 7a trannies bolt to the newer celica engines/ (maybe im wrong). Well may be a lot of fab...

anyways, do something that in the long run youll learn to appreciate, and not get aggravated..

You guys are looking at this like he wants to swap for power reasons. He HAS to rebuild his current engine, and isnt the 6gc moto"if it breaks upgrade it?" Hes not looking for power, hes looking to have his car running strong, and if it would only be a few hundred more to get some more power, then why not?

two things..

Whatever rocks your Boat!

Do it rite the first time!

Pick one...

Here is the thing, yes like i have said and suprakid has said the engine needs to be rebuilt or replaced, and being a college student commuting over 60 miles a day having decent gas mileage and a reliable engine is a must, yes a 3s would be cool but then you have to put premium in it and get about 20mpg? I do enjoy beating the living hell out of the car on occasion, but it is a DD above all. I would like turbo but then again reliability issue, not saying the 3s has reliability issues but im just going for a swap for a good price that is going to serve me well untill i graduate in 3 years and get another DD, then maybe a 3sgte, but this just seems like a good idea for the time being

If those are your reasons then I'd say you're right for going with a 4A if it's price-competitive with just rebuilding your 7A; newer engine with a little more "oomph" for a bit more cost-wise than your 7A.

I'm in the same boat but I'm going to go with Dan's second recommendation; rebuilding my 5S and then turboing it next year if I don't buy another car.

Good luck either way and have fun!

I used to be so set on swapping in a 20V, but after reading this, I think I'm going with a BEAMS, which was my first choice. Mpg doesn't matter to me because I was only gonna swap in the motor when I can retire my Celica from DD duty. Until then, I was just gonna get the suspension nice and tight and keep the 7A running at least. Hell, since I won't be DD'ing it, I might as well buy a super cheap GT shell, stick the BEAMS in there, and transfer all the yummy goodies from my ST.

Good luck with whatever you go with, Kyle

I still plan to go with the 20 valve now, i actually found the wiring diagram today so thats off my list, just need to find one for the 7a now and figure out what wires need to be moved

Bump.... back on topic, does anyone know which wires need to be moved from each harness for this to work?
