I was curious.. to see how bad it is to run turbo on a stock ls/vtec block..

Stock as i mean.. pretty much oem internals...*assuming its built correctly*

i know tuning is the key.. but is there harm done by runing a turbo.. of oh ummm 5-7 psi on a stock block? b18b + b16a2 head...

It runs great, a guy on clubsi.com says that our engines are designed for boost. You should be safe to at least 60psi.

Accord94DX

it was 70psi but ill forgive you

I hope you're just being sarcastic.

guys, ease up, i think he hit the "0" button by mistake trying to hit the "P" button with his thick fingers?

Your fine up to 7psi. 10psi is OK but not daily, at the track go for it.

hmmm what if the 10 psi is tuned with a dyno and wideband using hondata 2b? I was planning on running 9 daily. Please let me know before my dreams are shattered.

most of us run turbos on a stock bottom end...

b18cTurbo

u can run 10 psi whit proper tuning max(safe marge)

10psi on a good tuned system is

Depends on your elevation.

Typicaly you can boost 2 more PSI for every 3000 ft above sea level.
I would say 8psi is safe for sea level, asumming eng. man. is taken care of.

my kit comes 7.5 out of the box for my b18c1. im guessing its ok if GReddy says so =P I don't punch it much, I rarely get her out of vaccume. Only when im passing someone on the highway, or when im feeling saucy do i punch it.

just boost the damn thing already.

id say... no more than 9... but i would keep it between 5-7lbs to be on the safe side.

falcongsr

where did this come from?

lets see. higher elevation = less ambient air pressure, means the turbo has to work harder to maintain a given boost pressure = more heat - and youre saying its safer to boost more in thinner air?

whyzat?

I run 9 daily right now.....nothing wrong with 9 daily and good tunning.

turbocoupe

I think you have that backwards. . .
Yes 9-10 psi on a TUNED engine is OK. If you just slap on a kit and go I wouldn't run 10psi. Tuning is a must.

I have run kits 12psi with thick head gasket good tuning on a stock b16a block, they all have gone at least 40k no problem. Haven't blown one yet. Ooh yet (knockonwood) so your fine.. just tune

here we go....

The quote of "2 PSI per 3000 ft elevation" is NOT an actual mathmatical finding. It is just my experience with what I have seen.

I know of a Guy who boosted a ZC at 14psi for 3 years, with just a hi-pressure fuel pump, 12:1 FMU, and MSD BTM, at an elevation of 4000 ft. He sold the car, so that is why I only said 3 years. The car was also daily driven.

I personaly run 12psi daily, on my interally stock ZC, and have had NO problems.

Then I have heard so many stories of people around sealeval blowing their motors at only 6 psi, with the same setup.

BTW... 10psi at sea level is nothing like 10psi at 4000 ft. The 2 air combinations, have totaly different O2 contents, and there-fore at higher elevations you can boost higher. I'm not saying that YOU SHOULD boost higher, but THERE IS a difference in the maximum safely ran boost level.

I never said it's "safer" then boosting at higher elevations; I'm saying it's "safe" to boost a little "higher" then what the same setup can at sealevel.

yeah that's kinda... why... I said... "ENG. MAN." = Engine managment.
