7AFE weak engine????? Options

[macavely]

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..

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.
