D Series Boosted

Hey guys whatsup? Just picked up my Centerforce Dual Friction Stage 2 Clutch today along with my ACT Prolite 8.4 lbs flywheel pretty sweet....... But anyways I want to upgrade my valvetrain (Skunk 2 Stage 2 Camshaft along with whole valvetrain assembly) Can anybody tell me If this Cam is way to aggresive for boost or not.........

If this helps I am resleeving my block with new pistons and rods (Any suggestions on pistons rods would be appreciated) The head is getting ported and polished......... I would like to adjust my boost to maybe 15 -16 pounds of boost ???????? Is this realistic????????

Just in case you guys think im not considering all the other s**t I am.... like intake manifold, Injectors, Fuel rail, fuel pump, regulator blah blah blah and finally tuned ??????Can it Be Done??????

Goal to hit 12 sec in a SOHC Boosted by next year this time

Thanx for your time and replys

Every thin goyu have mentioned is possible...Though with that kind of money you are better off building a DOHC and will be able to acheive your goal easier and quite possibly with less money...There is a lot more tuning possible on a DOHC engine..Plus running on 15-16 PSI in a DOHC you will achieve more....12 seconds..I dont know..High ti mid 12's Im sure of....

But its up to you....Spend more on the SOHC or spend the same or less on a DOHC and exceed your expectations.

BTW the stage 2 cams will be fine...like you said you will need to upgrade, valve springs, retainers, etc., a GReddy timing belt or equivlent to handle the higher stress put on the belt.

I figure this is my theory you guys may think im stupid but meh
It is $3300 to get a 1.6L Dohc Vtec Engine canadian installed with that I can be pushin all if not nearly all the engine mods then I just gotta boost it.........I heard that pistons from a ZC motor will boost stock Hp to around 140 from 125........
If I have the engine basics before i boost it I will be able to run some pretty high boost numbers........

See alot of peeps just boost but if you prep everthing before boost then you have the advantage of runnin higher turbo numbers then the next guy.......

skunk2 stage 2 is too agressive for boost. get a turbo specific cam, like a crower boost cam.

 

[evan2]

^^ like he said get cams made for boost, the lift and duration on the stage 2s are for na
plus if you werent boosted you would need some more compression to really get power outt the stage 2s

if your going to boost sell the flywheel now and get a 12.5 lb flywheel, best for boost n the street unless your building a drag monster

if you stay na the 8,4 is great

you dont need a fuel rail, doh people get it right
you need injectors, fuel pump and hondata or better imo
fpr isnt really needed imo

greddy t belt, dont waste your money honda oem all the way

CP pistons for boost eagle rods

You really think so Mike? What are the profiles...

greddy t belt, dont waste your money honda oem all the way

Dude you need to upgrade the timing belt when upgrading the valvestrain....THe tension put on the belt is much greater when upgraded valve springs, cams, etc., are added....You are more likely to snap, shear teeth or simply damage a OEM belt without upgrading the belt....YOu dont see pro drag racers running on OEM belts dude..

TODA or GReddy belts I have seen on a few drag engines...

 

[evan2]

go to honda-tech most of the ht gods agree and so do I .. you really cant beat honda OEM when it comes to a lot of things
do you honestly want to claim greddy, some of the s**t they putout is junk some is ok
and trust me you dont need to run a diff t belt with upgradeed valve train

i dont, omnimans 200whp b16a doesnt and so domanyother high whp na stunnas

the toda belt is nice but so much cash on some bling...


look at the cars in jdm land, they rev to all high hell.. ctr still uses a honda oem belt

you cant go wrong with honda, why does everyong think greddy and toda engineers are better then honda engineers

i dont know

who cares profiles, bottom line the SS2 isnt made for boost... so ditch it

 

[Civicdreams]

Will I be losing alot of power becuz of the cams being to aggressive????
If the Stage 2 is to bad is the stage 1 suited for me better????

 

[evan2]

its not that you will lose power, but you could notice valve overlap, really just get cams made for turbo... the lift and duration would be better for ya

just get turbo cams

 

[evan2]

bad word choice, they wouldnt run great with the turbo... bottom line
plus they are somewhate aggresive for a small time set up

 

[Civicdreams]

coo 1 question do you guys think I would get more power out of a turbo on this engine or would it just be plain stupid to try and tune it with s charged nitrous lol

 

[Handlebars]

its not that you will lose power, but you could notice valve overlap, really just get cams made for turbo... the lift and duration would be better for ya

just get turbo cams

actually, with larger overlap, you are losing power. if you have a small turbo, you are having reversion- the spent exhaust gases has more pressure in the manifold than in the combustion chamber, so the long overlap allows them to seep back into the combustion chamber, increasing temps, cylinder pressures, and reducing the amount of intake air that can get in. if you have a free flowing turbo, you have blowby, where overlap causes the pressurized intake air to blow right out of the open exhaust valve, again, hurting power. get a stage 1 turbo specific cam, or get in a lose-lose situation.

 

[evan2]

look at my next post sucka.. haha
bad word choice thats all
and a tiny bit of valve overlap isnt death defying, gsr cams are good with boost but still have a bit of overlap

 

[Ravage70]

with a sleeved block and new performance internals 11s is doable
30psi will own u

 

[Civicdreams]

f**k man if i could boost to 30psi I will own alot of things first on my kill list CORVETTE lol..........
Do you guys think s charged is better in my case????

 

[evan2]

no never, turbo all the way for any 4cyl

 

[Civicdreams]

you think man, You woulnt do s charged on my D series with internals

 

[evan2]

hell no, takes power to make power plus sced power band is meh
depends what you want to be honest

whats ur goal.. ive been turbo and ive been in sc cars
sc in a honda was nice down low but up top it didnt have it

 

[Civicdreams]

oh yea that sucks.........I guess........cause I need mad top end if im gonna pull to 12's in the quarter........f**k
the problem continues......lol.......I need to get low compression pistons and rods and one thick ass headgasket

I went to my local tuner who is well respected in these parts and the sales guy was tell me they got some guys with D-series engines hittin deep twelves.........im like wtf.........boosted of course

Im gonna call skunk2 becuz there turbo cam for my engine is like to be announced.........

If i run 10 psi for daily street driving I should still have a pretty quick car........Maybe a GSR contender

f**k man on my way to work yesterday I saw the f**kin craziest sleeper.......Mazda like 323 hatch looked like s**t then we pull onto the main road so I start kickin in magnaflow and the Vtec screamin.........all of a sudden i here the bov go off and buddies car just like hopped and took off............WTF........... never be fooled by a shitty lookin car cuz this guy got my respect

zex mild (59100) camshaft is what the guys over at td16 recommend.

with a hatch, the proper suspension setup, and a smooth power curve, 210 whp is enough to hit 13's.
