I've already made my cosmetic and suspension plans for my Celica that will come in the future, but now I have to think about what is going to be under the hood. Sometimes it only frustrates me to think about it so I figured I would get some ideas and opinions.
OK, so far I've pretty much ruled out a 7a-fte project. It just doesn't seem like it will pay off in the long run. The minimum goal I'm wanting to achieve is 250 whp, and 250 lb-ft. of torque. How I get that... I really don't care. The problem I'm having is that I don't know where to start. I want something that is going to completely blow people's minds when they see it. I know that getting something like that requires custom work - and I'm not talking about the homemade kind (unless you're someone that knows how to do it). I don't know anyone at all that can make custom headers, mounts, intakes, piping, etc. I know that probably the most fun project would be a 7a-gte. I'm really impressed by frotou's project. After seeing all the custom work he's had done, I doubt I would ever be able to pull something like that off. I guess the only other option I have would to be a 4a-gze or 3s-gte swap. After seeing all the trouble that John went through with his 4a-gze, I'm kinda iffy about that as well. I know that the 3s-gte would give me trouble since I have an ST. I haven't done that much research about it. I don't know which generation of the 3s-gte is better, or if it's more common to find a USDM 3s-gte for the swap or a JDM 3s-gte. Sitting around and thinking about all this just makes me want to turn the Celica into a beater and save up for an EVO. But despite that, all my friends say I should keep the Celica and fix it up beyond belief. I guess that's the path I'll go unless a swap or hybrid project drives me insane. I am by no means a car expert, and I wouldn't even touch my engine in any way other than to change the oil, spark plugs, belts, or any other job that a monkey with a wrench could do successfully. I'm all about tearing it apart to learn about it, but I wouldn't consider putting anything together on my car without some supervision (I think I got lucky when I successfully replaced my front axles). I dunno, maybe I know more about cars than I think, but I'm still nervous to do anything big. Alright, I started rambling. So give me your ideas, opinions, criticism or anything else you can come up with. |

It's not that it's not getting credit, cause it definately has proven itself under boost, but as far as parts and power goes, it lacks. There are no cam gears (not to mention the 7AFE has only one cam gear), no ECU programs short of a standalone, and pulleys make little difference. It just lacks in certain areas, but things like that do not heavily affect how the engine will respond under boost. The deal is, the guy wants 220bhp which is probably not doable with the stock 7AFE internals. I would estimate 220bhp out of a 7AFTE to be at least 12psi well tuned.
Good start, but It's been said that 4AGZE pistons do not reduce compression, in fact, it raises compression significantly when compressing to the 7AFE head. IF you look at the designs, it tells a whole lot why that is... so that pretty much will strike out using 4AGZE pistons to lower compression in a 7AFTE set-up. As for blueprinting and balanceing... expensive and not needed unless you're gonna heavily modify the internals. Cams also are not a necessity for a boosted motor, although it's always a nice upgrade. I personally would do things differently... but that's just me. The compression in the 7AFE is low enough and can be brought down a bit more with a thicker headgasket, that you can boost a bit higher, so long as you supply ample amounts of fuel. The weakness is in the stock rods and pistons... -------------------- "It's ok to be naked girl... I'm an artist!"
