I currently have a st so i have pretty much desided i want to so a 4A swap, but i'm not sure what one? or should i rebuild my 7A-FE and either super charge/turbo it. I don't have to have a super fast car, just tired of the car being so slow. Any insight would be helpful. thanks

I would recommend redoing the mounts and going either 3sgte or beams.

3sgte will net you more hp, but if you wanted a light car a 4age would be the way to go.

From everything ive read if you wanted to make high hp out of it go with a blacktop head, 4agze pistons and rods, and slap a turbo on it. I know the 4agze rods and pistons are good for about 300hp (crank), never found any info on the various hp levels the cranks can take tho.

i figured someone would say that. like i said i'm wanting to use a 4A series engine, just now sure which one.

If you want to do the 4a swap, you can either get the blacktop/silver top engine and go high reving Natural aspired power. Another option you have is a 4agze swap, which is the supercharged version of the 4a engine. The 4agze engine is over built and can be turbo charge if you want more power later on.

If you do turbocharge the 7a or swap in a 4a engine, the tranmission will be a weak link in your car. There is no stronger transmission to switch in if you break it. That is why the 3s swap is popular because you can use a V6 engine or the mr2 turbo transmission with lsd ( certian years).

Like Hanyo said, If you want to stick with a A-series engine and emissions isn't a problem for you, then suggest getting a ae101 4agze. At stock it puts out a good amount of HP and torque. And like all swaps, you'll run into some trouble besides engine replacement would be like making a wiring conversion for the car, routing your vac. lines, getting other essential parts to get the engine to run properly, and redoing the exhaust system. But with the 4agze, you would need to make custom intercooler lines and run a front mount intercooler if the factory overhead intercooler doesn't clear the stock hood. And since it's a 16v, you can definitely find maintenance parts alot easier here in the US compared to another JDM engine like a 20v 4age. So consider going down the 4agze route, I think it would benefit better if want to stick with an A-series engine. And you can always boost it later in the long run when your up for it.

now am i correct that there are no aftermarket superchargers?

I havent seen too many different superchargers on 4a's besides the sc12 (what it came with) and the sc14 (off a toyota previa van). There is the twinscrew option and someone is working on making a kit but its still a ways off. Pretty much if you want forced induction and over 200 horses you have to go turbo. NA 20v would barely hit 250hp and even then it would be expensive.

well i'm looking for atleast 200 hp, but of course more would be nice.

hate to break the news to you, but if you want 200+ hp at the wheels, then the only swap that will give you that out of the box, would be the 3s.

yeah, kinda what i was thinking too. having an st sucks for a 3s swap though.

not really. its been done time and time again.

i know it has been donealot but i will have to spend more money.

well there is a upgrade supercharger pulley kit you can get to increase the boost on the sc 12 super charger. I dont know the exact numbers and specs, so I'm not going to say anything and spread rumers. If your serious about this swap you can head over to the corolla forums and search around.

Not to be repetitive, but...

Yeah, listen to Lagos on this one. Drop the 3s in there and you should be set. Consider putting a 3sgte if you want to turbo or a 3sge BEAMS redtop if you want N/A. You can go beyond 200+ HP with a 3sgte where as the BEAMS is somewhere like 200 HP at the crank. If you wanted the BEAMS to push more than it's stock HP, then money will become an issue. Just like a 20v 4age, to put over 200+ HP you will need to have an extremely large amount of cash. Everything in it needs to be replaced. And it needs to be in spec with the Group A 20v 4age (The one in Initial D) to make that kind of HP. Also, with that much HP, you would need a beefier tranny to handle all that power. Same goes with a 4agze, you can make a bit over 200 HP at the crank with a turbo, but at the wheels it will be alot less because of the weight of the celica. For me, I sold myself to Uncle Sam for another 6 years for my bonus and saving money on the side to want to make the 200HP 20v 4age even possible (Need to hide the spendings from the wife before she finds out and kills me). It will be a bit of a while though, but i'll make it happen and post on this forum when the time comes.

well maybe i'll go back to my origanl idea and go with the 3stge just because it sounds like i would be doing the same amount of work either way.

Yeah consider it, and feel free to ask anyone about the swap. There will be a few people to help out as much as possible.

well i've ridden in jgreening's car and liked the results he got from a 3sgte. just thought a 4a could make 200hp with less work

You know, I've been giving this subject a lot of thought lately, and I honestly don't recommend 4A engines to anyone anymore. Ever. You see, no matter what swap you do, you're going to end up spending a good amount of money. Then after spending all that money, if you end up with an engine that only makes 160hp on a good day, how's that feel? It sucks. And then you tell people that you did an engine swap and they're like, "Cool! How much power does that make???" And you answer. "well... 160hp". "Oh."

On the other hand, you spend some more money and get yourself a 3SGTE in there, then when someone asks you how much power it makes and you can say "250hp ", that feels a lot better. And when you get in the car and step on the gas and it scares you a little, you say to yourself, now THAT'S why I spent all that money!

So basically, if you're really on a budget and you really can't afford to do a big swap like the 3SGTE, then go for a 4AGE silvertop or blacktop. They're pretty easy and cheap to swap in and give a good increase in power compared to a stock 7A, if you're going to be happy with 160 or 170hp. Just skip the 4AGZE, but the time you get that done you're about $1500 off from the 3SGTE, and for the extra power it's worth every penny. But if you want the real thing, go 3SGTE. ESPECIALLY in a Celica, where the swap has been documented dozens of times.

another thing people dont realize is that the silvertop is WAY overrated and only makes about 120hp at the wheels. thats about 5-10hp above what you would get with a 5sfe. why bother with all the downtime and money, just to end up with a slow car?

You guys are making me feel bad JK. Both you and Doc are right though Lagos. Lately i've having the urge for more power on the Celi. I mean the 20v 4age HP felt great compared to the 7afe, but since I lost to a friend's supercharged TC i've been wanting more HP since then. I was thinking i've buying TODA internals for the 20v, but knowing how expensive it would be if I bought straight from TODA or Toysport. And since I still want to have an N/A engine in my celica, I wouldn't mind just swapping in the 3SGE Beams in the car. I don't need that 200HP at the wheels, I just want to have another screamer that puts out more than the 20v.
