Whats up guys. Well its been a while since i last posted on the forum. but i have a couple questions that i hope some of you could have awnsers to.
Its Mainy for the N20 Guys and the Boost Guys. so anyway here they are.

#1 Boost. I'll Be adding a turbo in about 6 months.. but i keep hearing this stuff about E.C.Us not reading boost and shuting down..i've read on what kind of stuff to buy to fix them. like a piggy back for the ecu and the synaps missing link. but will my apexi (vafc2) read the boost pressure as Zero or what this question is more of a wants to know how it works.....any replys are greatly appresiated (sp)

# Boost. Is there a pully driven Turbo availble

#2 N2o . Since i have hesitations on the ecu issues for boosting. im also looking into spraying what would be a safe shot for a stock internal d17a2. and ..how safe is it.

#3 Boost and n20 used together...is it possible. Any Dangers??

#4 Manafold Presure. A buddy of mine boosted his 97 ex. and add'd head studs to run more boost.. ..dont think he changed the head gasket ...but i also heard of this oppoxy that you use to basicly Clud down the head...any of you heard of this. and if so how much more boost do you think you can run w/ all the head support?

sorry for the long post.

Honda ECUs do not like positive maifold pressure as read by the MAP. A missing link, e-manage, and your AFC when used as a hack can trick the ECU into running with boost by keeping the voltage sent to the ECU by the MAP down. If you were running an SAFC I would say you could try the AFC hack, I don't believe I've seen anyone here attempt it on a 7th gen, but as far as piggybacks, the e-manage is showing promise.

There are no centrifugal superchargers readily available for this car.

Forced induction is forced induction a properly tuned nitrous setup is no more safe nor dangerous than a properyly tuned turbo setup. Turbo will make better power on the big end and doesn't require fills. Nitrous on the other hand boosts torque immensly and will provide instant power in lower gears, but loses effectiveness towards the big end as bottle pressure drops.

As far as a safe amount? common theory with nitrous on any stock engine, is that the maximum you SHOULD spray is 60% of the engines original output. So theoretically up to a 76.2HP shot on an EX would be safe.

Unless you have a built engine and everything that goes along with it, the reliability of using both would most likely be quite low.

If your friend changed his head bolts I assure you he changed his headgasket for at least another OEM/OEM style if he has any inkling what he is doing. Some of the previous model D-series engines had a problem with headbolts stretching under boost, which I assume is why he replaced them with ARP hardware. the D16Z6 ARP head bolts will work for the D17s as well.

As far as epoxy It's probably HondaBond you're thinking of, it doesn't really keep headgaskets from blowing, as much as it helps you maintain alignment when you're reassembling the engine.

How much boost can you run? Who knows. It all depends on the tuning, and frankly there are not too many viable options available yet. I've used Hondata to run a reliable 9# on a customers RSX-S which is running 11.5:1 compression. Jason form Autologic routinely turns out B-Seris hondas making upwards of 320whp on stock bottom ends using Hondata. Full-Race made 427whp out of an all stock H22 with their bolt on turbo kit and tuning with Hondata... See a pattern here I'm a Hondata *****, but until it is available drop in for the D17s my advice doesn't help. I'm sure some of the paid advertisers on this board working at turbo development could give you a much better idea of the performance envelope a stock D17 can be pushed to.

In my mind from my observations of other D-series... with ample tuning, there is no reason people here can't make 220whp reliably out of a D17.

^^^ yeah, everything this guy said. Except, only the afc II will work with the D17's and i don't believe anyone has completed the hack on the afc II.

Most people will say 50 shot wet if the highest shot you can do safely, but I've been spraying nothing but a 75 shot wet w/ stock fuel system for the past year with no problems yet. Car is still runs like a champ.
