How long has your tubo set up lasted?

[deevergote]

Nobody says "bar" around here! 15psi, right?

If you replace all the guts with stock stuff, and run 1 bar... you might last for a while with good tuning... GOOD tuning. At 15psi, you'll easily crack a piston if something goes wrong. The heat alone might do it (so, to be safest, run a larger turbo... no 14b crap! and get a good intercooler!)

Still, if you're going to totally tear down and rebuild the engine, spend the extra for forged internals. Stock sleeves on an F22A will be alright for 15psi and some forged innards, I would think. Above that, a resleeve would be wise.

yea i agree, forged slugs should hold on a fresh stock bottom end/ARP headstuds and 14ish psi

[MRX]

MRX's setup lasted what, 2 years before it finally gave out? That was largely due to a properly sized turbo, good tuning, and intelligent driving (he didn't beat the living piss out of the car every single day). He had stock internals.

2 and a half or so, it wasn't even power that made the motor fail, it was low oil lol.

[deevergote]

Low boost setups on stock blocks will rarely blow the motor due to power... sometimes heat... but the added stress of the turbo will accelerate any normal wear.

Or, you could just run out of oil Do you think it would've failed as quickly, or as fatally, if you weren't boosted, Antoine?

With all my research as of late, I honestly think N/A honda's go through a lot more stress than turbo honda's do.

Especially F/H series.

There is more force to push the piston down, but it's at way less steeper angle than that of an NA setup.

Long rods+long stroke=disaster when you add too much timing. Hell, even with stock timing, just revving the piss out of the motor, even if it's just to redline, puts a hell of a lot of stress on the bearings. The crank angle in our motors when the spark fires is just insane.

14b turbo (really not the proper size for our motors).

14b are good for the F20A motors

They're actually for dsm motor

TRU DAT

[Accord SiR]

first setup, stock motor with inline pro thicker headgasket, went for about 1.5 years. conservative tune. Blew the motor by over revving it the day I got my 3" exhaust welded up. Hey what can I say it was like night and day and it built boost up quickly.

second setup went strong for 3 years. Took it apart to do some minor upgrades/freshening up. And always drove the piss out of it and she was still running strong.

The car will last as long as its built properly and tuned correctly. Its all in the tuning. Stock motor can last, there are a few h22a that have proven that but its all in the tuning.

The DSM motor is a 2.0L... so yeah... the F20A would be better matched to it.




And SiR is absolutely right... get a good setup on a healthy motor, tune properly, drive with care, and it'll last.

I didn't realize your first H22 lasted a year and a half, Carlos! I thought it blew pretty quickly! I remember that conversation we had, and I got the impression that it was a VERY bad idea
I still think boosting a stock H22 is very risky... especially since these motors are well over 10 years old, in most cases. Even the low mileage ones may be worn (sitting for a while can do some harm as well)

[Accord SiR]

The first setup lasted for awhile. But the most boost that setup saw was 11psi. I wish it would have a lasted a bit longer. But what can you do. Due to the h22a thin ring landings is the big issue with boost and with stock internals.

[c mak]

8 months untuned on 10-12psi with a basemap; Stock block before I broke 2 ringlands on cylinder 1 . Time for a rebuild with some higher comp pistons , going all motor again for reliability issues.

[h22sparkle]

yeah mane ringlands is a mofo when i first boosted mine the only ringland that lasted was cylinder 4 went got it built it lasted for another year and a half and traction was a bitch.

[deevergote]

Yeah, stock H22 ringlands and turbo don't go well together! How long did that last, Mike? I don't even think I remember when you were boosted before you got it built!

What was the cause for the failure of the built one? Was it something to do with the way it was put together?




That's one thing I don't like about turbo, especially on motors that aren't initially designed for it. It adds stress on parts that weren't made for it, and it introduces a bunch of factors that could end in total engine failure if they fail.

I probably said it already, but I'd never have a turbo car for my only car. ESPECIALLY if it's a Honda! I might consider something that was boosted from the factory (though, once you mod those, you run into the same potential issues). I don't think I'll EVER have just one car again, though I've got 3 now!
