7afe quition? Options

[97celica_st]

I was wondering how well does the 7afe stock engine internals hold up with a turbo?

[96stgreendemon]

around 8lbs is roughly what it will hold, people have run more but its not really an engine to boost

[Smaay]

my kit on erynns car is making about 8 lbs

[97celica_st]

On 8lbs of boost how long will the motor last? Because I was reading a post of a guy with a corrola with the 7a and he had a turbo kit but his motor only lasted about 6 months befor the ringlands practically dissapered.

[Smaay]

must have been a tuning issue. if you get detonation then yes that is to be expected. Erynn has been beating the hell out of hers for over a year

The 7A pistons are pretty strong, there must be severe detonation to kill them
I was boosting 8-11psi on the racetrack for two years and up to 13psi with my street setup without any piston problems.
With a good and safe tuning the engine should have no problems with up to 250bhp.

List on your profile.

Hi guys,

Anyone know where I can buy a turbo kit built specifically for the 7a-fe? I'm based in the UK but am willing to pay for delivery if the kits proven to be decent. I'm only looking to get around 180-190bhp.

My new engine will be build with the wisecos because it's intended to have quite a bit more than 250hp

How much Does it cost to have wiseco make custom pistons for the 7a?

I got them for almost 800$ with rings, but i think you could get them much cheaper since you don't have to pay all the stuff to get them over to europe

ill make you a kit and ill send it to UK, no problem. i dont know how much power its making since i cant get erynns on a dyno but i know what 200HP feels like and this is definatly in that range

I can have 7A-FE pistons made for about 600 from Diamond. I use their pistons in some of my high HP 2ZZ engines. they are made out of a better aluminum than wisecos are. they are a tad lighter and stronger.

[presure2]

What material are they made of, smaay?
Why can't you get ereyns car on a dyno?

[Smaay]

ill have to ask, he told me like 2 years ago what it was but i just cant remember. as for erynns car. we live 100 miles apart and its tough to coordinate. its not for a lack of trying

[Hafkai]

Both manufacturers use the same 2 alloys, 4032 for more durable street engines and 2618 for higher performance engines.
I actually don't exactly know what my pistons are made of but i think its 4032, but they should handle at least twice the power i will run anyway
