ok i have a stock d16zc sohc vtec with a d15b7 tranny what is a good safe boost psi to go??

 

10lb(it will last you awhile)....dpends on your budget too. more boost will call for quality parts
sissies will tell you 8 or less. but ive seen around her stock Dseries go to 15lbs all day long daily driving. all in the tune though

 

i'd still go at 8psi

 

10 lbs will be fine. i have a buddy with 20 pounds on a bone stock y7

 

^^see, its doable...but overtime the motor will give after abuse.
i say that cuz i abuse the crap out of things

 

i would say 8-10psi would be safe. It really comes down to how good of a tune you have.

 

i new a guy with a bone stock d16z6 ex model with 150,xxx with just a built head and arp head stunds with a t25 turbo runing 15psi, he tryed to break the thing, couldnt do it, untill he took her on the highway one day really pissed off and ran her super lean, then dropped her from 5th to 3rd and out came pistions ,oil, an smoke. gota love hondas .

 

i think his honda sensed his anger and didnt agree with him

 

If you go ANY HIGHER than 9PSI, I strongly suggest upgrading to ARP headstuds.

Z6 tend to have head lift at around the 11-12PSI mark, but it is hit'n'miss.

Some will lift at 10PSI, others will go up to 18PSI.

Me personally, I have been running 10PSI on a stock Z6 w/OEM headstuds no problem.

Also, the OEM Honda MAP sensor is good to 11PSI, so if you wanna go higher, you're going to need an aftermarket pressure/MAP sensor.

Hope this helps.

 

thank you guys

 

boost that bitch 15 pounds! it will last a while as long as you don't get on it all the time.

 

umm yeah, i just ran my d16 turbo del sol, with a Stage 2 crower cam, ARP headStuds, .030" over Cometic Headgasket and stock block and a little over 20,xxx mi on it, at around 10-12lbs of boost, and put roughly 4 holes through my block and had piston/connecting rod/block parts all over the road, i would be careful. I blew out my block at around 4-5k rpm's going roughly 70

 

There is no such thing as "safe boost level". It is addictive. You might start at 5psi and your engine MIGHT hold together. If it did hold together you would get excited and bump it up to 10psi. Again, it MIGHT hold together. If it did you would get excited and bump it up to 15psi. This could go on for a while, but when you least expect it, it will let go, and violently. Then you will spend a ton of money building a new engine that can take the boost (because at that point you are addicted and you HAVE to have boost). And the cycle will start again.

Anyway, I say go for 8psi. lol.

ah...the cycle....the...vicous...cycle... i have no $ now.

 

what is a good compression ratio for a d16 for a lot of boost? i have been told too low a compression and you will have no power till it spools up. any help is appreciated
