Why do alot of people around here think that the 7AFE is weak and can't handle boost? I just want to know your view points on this? Do you think its cause it's and N/A engine? Is it because it comes from the factory with only 110 hp? is it beacuae you know someone that has boosted the engine and it has blown up? or any one of the many other reasons you might have?

I just really want to know what all you guys think, that say the 7AFE is weak and people shouldn't spen anymoney on it other then a intake or exhaust system..

Dont worry bro, they have no idea what their talking about. Pretty much just what they heard in another post and it happened to stick with them. We shouldnt spend any money on either engine if it isnt a damn swap.*thumbs down*

Should i change my sig to: i am a nerd who doesnt know anything about Celica's with a silly hood scoop?

CR for the 7afe is 9.5:1.

not the best for turbo, but its definately not high up there.

turboing does bring good results, but its custom work, and you ahve to know what you are doing when it comes to custom work.

i had my oil return line break too, but i noticed the problem right away, pulled over and cut the engine t inspcet the problem.

i check under my hood daily.

i check my plugs once a week to get an idea of whats happening inside.

the 7afe is a good engine, by far not a performance engine. the two reasons why it only has 105-115hp are the economy head(small valves, different angles) and the CR.

the head is the main reason why the 7afe makes for a lousy NA power motor. it is the limiting factor.

the main difference between a 7afe and a 16 valve 4age besides the displacement is the head(the internals might be different, i know the crank is). a head swap, while very costly, would not only net good gains, but also make gains from other mods more meaningful.

i have driven 4k miles with my turbo setup. no major problems.

if you dont beat the engine to death, check it often, let it warm up and cool down

you could make a 7afte setup very reliable. corolla guys do it all the time.

the 7afe may not have power, but it is still a Toyota engine, reliable and hard to kill. turboing will shorten lifespan, but if you do it right, only 15% of lifespan will be lost.

my 7a was a tough little bish... i finally learned why i had an oil problem.. it was actually an internal motor problem, yet i still ran a few thousand miles with it, and it still yeilded good vacuum so i never though it was a motor problem.. i probably pushed the envelope a little too far with mile but it was FUN while it lasted.. i got a good amount of kills with it. like my friends VR6 no1 could keep up with, gave a hand full mustangs a kill or a good run. the 7a has not yet been really pushed by many, theres a lack of info on the motor out there too. 7age is possible, i built a 7afte so that is possible, so a 7agte is very possible too. there are internals to be had by cross referenceing parts but its not very know about yet. theres a huge arra of grey in there. i was afraid to swap at the time so i went 7afte.. i learned enough now that i fell i could do a swap.. im still gona have problems but im not as afraid of it. it was a great but expensive learning experience. once i see how bad my internals are i might just put her back together, or save the parts for a future project, try it again, maybe in a corolla this time.. who knows.

too add to 97... the g head swap alone doesnt yeild good results, add higher compression and its a different story.. theres little info about this out there, but if you take the time looking you could find some.

man thats a lot of work, and being on the ground wont help

a quick way to check the pistons is take out the plugs and look at them, you wont see much but if one is really really bad you will notice.

but the oil pan and valley thing is a good idea. with the pan off, you can easily see one of the rods and a piston, but with the valley off, im sure you could see everything except the top of the pistons

good luck, dress warm.

Kwanza, I dont know what you are talking about. In no way shape or form was I reffereing to you. In anycase why dont we all just do what we want to our motors keep it all safe and stop with the whole "wasting your money" pitch. Both engines will handle boost w/o overkill and the 4age and 3sgte are both outstanding motors but its not for everyone to swap. To each his own.

Woah...I missed this topic >>

well i think the 7a has potential to be powerful even if it is an econmy car look at civics there made for econmy also with the exception of an si but look at the power you can get out of there engines. The thing is with the right amount of money there is no limit of what can be done to make your engine more powerful

my 7a was shy of 200 hp.. my best dyno run put 184tq ant 173hp, we didnt print that out thou cause we wernt finished tuning it. it was in tune to run a little richer to avoid lean conditions. so my number fell but when i turn up the boost a little more that extra fuel is burned and they car lets you feel the difference whenn u turn it up an extra notch or 2
