How much boost do you run on a stock D15?

- Mon Oct 26, 2009 9:18 pm #152888 Just curious as to what you run, or what you think is safe..

I seem to keep getting the same response when I say I'm running 10psi on an all stock D15B7. I've been running it for a year no problem, no gasket changes, and absolutely no mods/upgrades to anything except the injectors/rail, and exhaust.., obviously because I had to.

What say you?

i don't recommend going much higher, though.

how much power/torque are you making?

- Tue Oct 27, 2009 11:16 pm #153221 D15B7 au-natural with a T3/T4 ebay setup. Never planned to boost it, but when I found a kit for $575 shipped, I dropped the cash and did the install myself (minus tune and gauges). The kit was actually pretty good, not just some crap thrown together.., was impressed.

The chipped and tuned by dyno inc. (now out of business) in va. beach.

As for upgrading, I am.., but not the bolts per say. I'm deploying and will be dropping a fully worked ITR under the hood when I get back. I love the D, and I may keep it to learn engine building on while I'm in Italy, but it's time to move along.

Thanks for the input!

- Fri Dec 11, 2009 12:56 am #161140 My dyno sheet says 170. I need to replace that god awful obx rail, new filter, etc and I'm sure the numbers would improve a little. I know it does a solid 170+ because I took down a solstice (factory says 173) from a roll. I went looking for a GSR but it had to be the one night that none came out :x A guy in my club was pulling out in his solstice and invited me for a stroll. When we let loose, he shot ahead like a rocket.. As we all know, D-series torque leaves a LOT to be desired. But, I slowly reeled him in for the kill. He wasn't too happy about a d-series honda civic beating him :lol:
