If I decide to upgrade and go with higher compression(thinking 10.8:1 from dh racing) how would I address the fuel issue? or is there even a way? thank you in advance for any help on this.

jus use higher octane gas.

thats all i need is higher octane gas? i won't be running lean or anything? and also is it still safe to use nitrous with that setup? I will be upgrading the rods as well

if ur going to go FI why do u want to up you'r compression? lower compression when going with nitrous, or turbo is the best.

the computer should make up for the fuel mapping up to a certain extent otherwise you can search for the DIY of a inline fuel pump and slap a fuel pressure regulator on it and it should help with your problem

I don't want to go turbo due to all the ongoing maintence required with it. Its a non-stop process trying to keep it running and i don't want that. I'm going with the higher compression to have a little extra power under normal driving and nitrous is just nice for when you need that extra boost. But can anyone tell me if they've done this or not??? thank you

seems like just higher octane gas will work.. your engine will run hotter, uh.. might want to look into the egr valve, because that will try it's best to keep NOx down

we do have a fuel pressure regulator, it's in the fuel tank

im sorry an easily adjustable fuel pressure regulator, the computer maps it out more then an older car with a manual fuel presure regulator sorry for the poor wording on my last comment

i know people than run 13.0 compression ratio you just need proper tuning and to retard timing, im in the process of building my hih comp motor but thats with a d16 someone on here used some gx high compressions pistons in there engine the power was great but they had overheating problems

yeah i think that was chrissy...

You will have to do ongoing maintaince on n/a or turbo setup. The parts just change in what you will have to do maintaince on.

mclean987 buddy...if you add more compression you need to add more octane or you will detonate. If you retard your ignition timing it is cancelling out the compression you just added...read your other thread i replied in more detail there...

If you want to make power you want to advance your timing...read up on some facts before YOU give advice on something your BUDDY doesn't know about.

And how do we know "Chrissy" even did anything she said??

Listen, Boo, I've been thinking about doing this too, and the computer should adjust for the higher compression. 10.8:1 isn't too high, but you will have to start using premium gas. I don't think there's one person on this site who's done this cuz they're all to scared or something. So be a pioneer and let us know. I just don't have the cash on me to do this project.

Just curious, I have some money to burn, but I am hesitant on the turbo mod. How much would a high compression piston + ring set cost me + labor??

 
Rep Power: 0

well if you notice i said tuning is the key so obviously when you tune you will adjust timing where it sposed 2 be, i know people who run d16a1 and d16a6 p29 jdm dome pistons in there sohc vtec with a **** load of mods and cams and no b series engine can beat it

Its different trying to tune a d17 compared to a d16. If the D17 was easy to tune people would be doing it then........has anyone adapted an aftermarket radiator to our cars or is there one for it to address the overheating issue?

 
Rep Power: 0

The whole package should cost you less that $1000. I could get it done for about $500 but I just don't have the money. My uncle is a mechanic and he could hook me up with cheap labor. The pistons/rings should cost you at the most $300 - $330. That's not including rods..

i never read the thread about the gx pistons chrissy had

but i am sure she probably killed her cat, and her egr

if it was simply adding higher compression pistons into the car, there would've already been d17s out there running that compression, obviously, it's more difficult dealing with that overheating than just a simple bigger radiator

you would need to retard the ignition timing elctronically through hondata
or JetChip. not retard the cam gear..

 
Rep Power: 584

hondata doesnt exist for our cars and never will according to them, i wouldnt say jet chip either, bc once u do it i dont think u can change it back correct me if im wrong, i retarded my timing with the emanage

And what is your "tuning" consist of? and like i said if you raise the compression and retard the ignition...your cancelling each other out...get a clue.

 
Rep Power: 584

mine consists of a turbo where that is beneficial

 
Rep Power: 0

but would it be so hard for someone out there to at least try it? it seems like most people who have a D17 in their car is afraid to change their internals. i mean, i go on clubrsx, and a lot of people there upgrade all kinds of crap in their engines. they upgrade everything from pistons, intake manifolds, cams, and more. if more people with D17's tried to change the internals, and revealed actual results, i think we'd all see that it's possible to have a faster car without an engine swap.

ok... so how much HP to the wheels should this upgrade possibly add??? that's the most important part of all

 
Rep Power: 0

what do i look like? a dyno?

j/k. seriously i don't know. it should add some actual "noticeable" power compared to what we have now, though.

again, NO ONE will know unless SOMEONE tries it, and then let's everyone else know.
