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

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

my kit on erynns car is making about 8 lbs

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.

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.

You are runnig custom wiseco pistons tho? Because I've read your parts
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.

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

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

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
