i have a rebuilt d16z6 with:

stock pistons and rods
arp head and connecting rod bolts
stock headgasket
4k miles on rebild
act hd/ss clutch
t3 externally wastegated turbo .42 turbine .48 compressor (not 100% sure)
walbro 255lph pump
dsm 450 injetors
1 step colder plugs
beerbongskickass uberdata file with conservative timing

Do you think 12 psi is too much, I will be running 93 octane plus 1 bottle of N20 brand octane booster per tank

if I use my buddies wideband to tune will this work

I just spent 1 year building this up and really cant afford a new motor untill feb, when I will get a fully built 20 over bore sohc

and should I expect over 200 whp?

I would convert my 1.65 re-pack 3 maps over to 1.66. Just import the maps directly over and it should give you a decent basemap to start tuning from. I think 12 psi would be fine if it's tuned well.

that octane booster doesnt do **** . and ive seen people run more boost forever , but every motor is different. personally id keep it at 10 lbs . run the 93 and get it tuned well.

yusoslo

i thought it wouldnt hurt to increase the octane to 100

anyways anyone ever think of water injection into the intake mani (or throttle body charge pipe?)

I have talked to tractor drag pullers around my area that run 120psi on their engines and say water injection cools the piston temps alot!

yusoslo

any more opinions

USDM 4G VTEC

yea dont run that octance booster

doesnt work for ****

i onced used it on my N/A aplication and made my car run like **** and sluggish.. i used all the gas down to empty and once i filled it up and ran a few miles i got the power back

SUCKS


i say just run no more than 10psi or the rods will let go

yusoslo

i was hoping for 12 pounds cause the the uberdata tuning would allow me better control over detonation


or are you saying that the rods just wont handle that kind of hp?

yusoslo

also will I have any problems with 2.5" intercooler piping?

If you want octane booster that will actually boost your octane go with xylene or talulene... it works pretty well

beerbongskickass

2.5 inch intercooler piping will be fine, that's what I am running. I think with your t3 .42/.48 turbo your car will handle 12 psi just fine with good tuning. The same guy that tunes my car had a friend running 14 psi (big 18g turbo) on a stock ZC for a while and his rods held up. I have been running 10 psi with a bigger turbo than you have for a while now, I also plan on running more boost at the track. 92 or 93 octane should be fine also.

yusoslo

your hp levels are really good, i was hoping to suceed them with more boost and some wide band tuning. I really dont know how much less power I will make with the smaller turbo but maybe I will have a broader power band to make up for the loss in peak hp

I tried that. FOr some reason, my fuel maps switch in the boost levels. Anyone ese have this? Im gonna IM you cuz i need to kow what the hells going on

It seems like they go too lean. Can't wait till my techedge comes.......

beerbongskickass

What do you mean your fuel maps switch? The vacuum and boost columns numbers at the top are a little different in the 1.66 version, but it shouldn't matter that much, I didn't notice too much difference. You sure it's running lean? It should actually be running a little richer at WOT if anything because all the boost columns are beignn used.

yusoslo

what is the benifit of using 1.7 over the 1.66 that you already have set up?

aside from fuel and timing changes
1.66 has full throttle launch, and boost cutoff right?

thats kind of all I need

nonvtecD

Use 1.66, it's fine. Tune it right, run conservative timing and you'll be fine for 12 psi. It's detonation that kills, so dont let it detonate.

yusoslo

i wish I could have afforded to build the motor with rods and pistons........do you guys think the arp conneting rod bolts will help at all with increasing the threshold of power I could make.

yusoslo

anyone else running 12 plus lbs of boost on stock rods?
