Does a mans word not mean anything any more?

Are Subie turbo engines that weak where I'm constantly hearing about blown motors?
Whats up with that?

Most cars don't have the absolute piss run out of them like a scooby. I don't know anyone that's had one that didn't just molest it like a sheep at a Montana bachelor party



Not that I've ever been to Montana

I've not heard about blown motors, but transmission going out in them. What I understand is that when they add "toys" to the engine for more HP they don't upgrade the tranny and it just can't handle it.

I think it's more like what Troy said in having the piss ran out of them and not being taken care of the way they should.

the issue is exactly what you pointed out...

but lets look a little closer:

the 02-03 tranny has the worst reputation, it was ment to hold 164whp and does it well
this is the first generation of the usdm wrx and in stock form it is fine, you start adding go fast goodies it reaches its limits fast and blows 2nd usually sometimes third, but adding a stage 2 which is just some pipe work and a Accessport tuner and your looking at adding 50hp and more torque. I more then doubled the hp and its holding it, i cant get wild and abuse it but i knew that going in. the rule of thumb is that the 02-03 can safetly hold 300hp at the crank, the sti which has thicker gears can hold 400hp at the crank which is still a little less ~ then i am making, needless to say i have never launched my car

as fas the engine is concerned a major issue is oil starvation at the #4 cylinder due to the oil sensor being set at ~3 psi and its just too damn low, once it hits that low the damage is done, which is what happened to me. when they rebuild the car they replaced it with a aftermarket unit that is set at 12 psi, which is well above the safetly margin, so if it dips i know i have a issue before we have reached the land of its already fucked up.

the main reason is its so stupid simple to just crank up the boost and disregard the reliability of the engine, if 14 psi is good, 25 psi is god! well it will make power, till it doesnt any more lol, to safely make power the supporting mods need to be in place and most ppl skimp on them unfortunately

Like trying to run 32 psi boost on stock internals

Too much boost plus on the stock components just finds the weaknesses.

All that "extra" boost keeps my friend Kurt busy at the shop.

Wow! 3psi oil sensor. That is dumb.
