Ok I was thinking about this for a while well over a year. First I was thinking about a 3SGTE swap then chose thought a 4AGZE swap would be more economical. Now I see that a turbo set up is the way to go (for me at least), because of price, availability.
Yea a lot of people might say that if I can take the 3g’s that I’m going to spend on a turbo setup and just do an engine swap. Yea I don’t think so. I’m taking a page out the playbook of those crazy corolla guys. For some reason the love the 7afe engine and I found out why. They have been boosting then 7afe to 280 hp on stock internals. I have found a few sites that have everything I need to do that too. 280 hp from a turbo What do you some of ya’ll think about his? -------------------- |

I think that a stock 7A-FE running more than 10 PSI is not going to survive long at all. It would require even more than 10 PSI(I'm guessing 17-20 PSI) to achieve 280 horsepower, which would destroy a stock 7A-FE incredibly quickly.

na i was talking to a corolla guy he has been running 11psi for over 4 years now... with no problems...he says the 7afe is great for boosting alot of people think cause it's and fe head that it will not hold but it holds up to the boost great.

I don't think the 7A-FE can take anywhere near 280 HP in stock form -- especially coming from a Turbo. I didn't read that site fully, just quickly scanned over it, but I don't recall them saying that the Turbo would do it in stock strength. Just my opinion. But good luck!

That's interesting. Is his 7A-FE stock? Also, I'm sure he's not anywhere near 280 horsepower by the way.

280 ain't gonna happen. First I'd like to see somone with stock internals on a 7afe boosting 200 hp reliability.

I'd like to see a 7A-FE transmission hold that much power...they can bearly hold the 100hp that the stock engine produces!!!

I bet the tranny can hold it (toyota trannies rule!)... the head can do it, albeit a bit restrictive and fairly poor at heat dissapation, but it can do it (might need to upgrade some components...but it's a good head, even in stock form)... the thing I question is the crank... it's not a particularly tough crank...

But is this a car your going to be using everyday?
If he's boosting that much he may be only running it sometimes. -------------------- |

What is the Benefit tho? its going ot cost you 3,000 just for the kit. And then your running a risk of blowing ur engine. Just because some guy did it doesnt mean it will happen with you ya kno? You can do the swap for that much and have a car that can be boosted to that power with less potential of disaster.

ok for me the benefits is a turbo setup is a lot more resanable....
i just want 200hp that my max... i don't want more no now not in the future... well not out of the celi.. and parts will be a lot easier for me to get if anything does happen... a whole new engine, 0 miles on it will be easier and cheaper for me to get if i do blow mine up by boosting it... and i will pass my inspection also... if i get an engine swap i won't pass inspection... New Jersey is kinda strict on that...and i'm sorry but if i do a swap it's going to coast me around 5000 after everything is done... for a car that i wont be able to drive everyday.. -------------------- |

well, i think the best thing about turboing the stock engine would be that i can go in my garage and 45 minutes later the car will be NA again
and please dont spend that much on a kit. dont forget that most likely the piping wont work and the exhaust stuff they give you will have to be modified. also the turbo that comes with that kit is small and i highly doubt that they can get 280hp with it on a 7afe. as of now im running 8psi on my setup and believe me, thats about all the power i want with a FWD car. i have gone to parking lots and going through a hard start with my hands off the wheel and the car wants to fly in a different direction everytime you can have a good setup for about $2k if you take your time gathering the parts the 7afe engine may not be all that strong but im sure it can reliably handle 200-220hp and last for quite a while but anything above that goes into really high boost levels. with any engine, so long as you make sure it gets all the fuel it needs can be turboed to make a lot of power over stock HP and still be pretty reliable. the stress on the internals is not as bad as some of you think. it is more stress but the fact that the engine is making more power makes the engine handle the up and down motion of the pistons more easily due to greater momentum. if maintained, and not driven hard all the time, a 7afte could make 200-220 hp reliably and last for atleast 75-100k miles depending on the condition of the engine before the turbo was installed(mine had 13k miles on a rebuild) and for most of my driving, i dont even hit boost. an engine swap wil always yield better performance but at the cost of long down time, potential insurance problems, in my case more money, and emmissions problems. and really, some of you guys shouldnt be so doubtful of something you havent tried -------------------- 1994 Celica GT4 WRC Edition

thanks... and yea i know that kits pipping might be not fit the celi but i'm just using that as a guide to everthing i need i'm going to start using some of my hookups to see if i can get all the parts i need new... at a lower price and GT2GT4 yea i know it is misspelled but i don't feel like changing it so it will stay like that till you'll see the repainted celi .... -------------------- |

You guys are way to cynical about this whole deal. The only thing I'm gonna add to this is never say never. You guys are so skeptical because you've never seen a 7a-fe do 280HP. I mean sure, we know the facts about the engine, and it wasn't built for that much power, but hey, you never know.
Dreams can come true. |

I'm not debating that it can't be done, becuase it can, just not on stock internals. It'll just require a lot of money and work.

Just re-build it first. In the long run, you will be better off.

Im with macavely in the sense of screw a motor swap. I know alot of you are hardcore 3sgte fans but for me and my GT the burien T-kit will do just fine to lay out 170whp(intercooled). Im not looking for drag but i wanna kick ass. I say to macavely do what you can and if you blow the motor go to E-bay and get another, youll never know the limits with out some complications. Im doing the T-kit and I really dont care about about a swap, ctually the more I think about it it pointless. If you want a 3sgte why not get the real thing. Youll spend close to the same on it with the price of your car plus the swap. But anyway thats my opinion.

if a 7afe can handle 25psi for a week of driving(even after it had lost all its oil at one point, and over heated a few times before the boost was turned up to 25psi), than impretty sure it can handle the psi needed to make it a 200hp engine. no one will know how much a 7afe can take if they dont try. i might try to find out this comming year before my warranty runs out. -------------------- 1994 Celica GT4 WRC Edition

10psi would be enough for me
Hey mac, you might see if they'll send you 4agze pistons in stead of stock 7a;) Jon |

I got my 4AGZE pistons today and I'll put them when I'll do the whole turbo thing.... Anyway since I don't know the measures of 7A pistons I don't know if the compression rated for the GE head will be the same of FE head....Who know this????

Yeah, but if you're limited on funds, it's not fun wasting money on an engine that will requires LOTS of money just to be able to compete with an engine that's already built for performance... |

u gotta be kiddin. im only 40hp away (dyno proven.) and my safc settings were not 100% correct when i took it down to the dyno. there were also no fan to push air through my IC. 200hp is not a problem, im probably putting down more than the dyno says b/c of thoes limiting factors, and its still running STOCK injectors. so upgrade them and i could be fueled to even more. |

40 HP for an economy engine may not sound like much, but it is... once you reach 200, I'd like to see how reliable it is... I don't have first hand experience with this, but there have been board members (on Celica.net) who's applications didn't last them very long... I think 180 was one of the highest someone attained with the 7A before it blew... Good luck with your project tho bro. I would definitely like to see you succeed. There aren't many people doing what you're doing, and if you do reach 200HP reliably, you'll definitely give hope to a lot of eager tuners. Keep us posted bro. -Ray |

macavely, how far along are you on doing this? it's something that i'm seriously considering, and are you going to swap transmissions? was looking at first at swapping but if you can get 200 hp i'll give it a go!!! good luck and keep us posted on your progress.

i was thinking a bit more and was wondering if there are any transmissions that will bolt to the 7a-fe that either come with or have an aftermarket lsd available?
