Is there another route to adding more Hp to my motor instead of adding more boost? I have a B18C1 with 273.5 whp and 204.2 tq @10psi on a stock motor right now. I want to add more hp without adding more boost is there a way to do it besides adding a exhaust, DP or Filter.....(should i build my head)...thanks for any info

 

-Tuning (depending on whats currently been done)
-cooler intake charge
-more compression

 

All of this together will see the greatest gains: larger TB (needs inside diameter to be bigger than IM diameter for best results), ported/new IM, ported head, larger cams, cam gears(if you don't already), smoother flowing pipes, ceramic coating on exhaust manifold (doesn't really add power, but aids in spool time). If you're running lower than stock compression I wouldn't recommend running too large with the TB unless you like lag then a sudden rush of power. I do, but I run higher compression so it's not as noticable.

Oops I forgot a few things like what the guy above me said. Sorry a little tired. 48hr. days own me.

Do you guys think i can add a thin headgasket to raise compression to make some hp? i want to hit 300 whp. That is basically my goal....

 

how bout you list your mods so we know what you already have

 

yea ok...i have a stock B18C1 with a drag 3 kit, hondata 4b, 440cc rc injectors, 2.5 inch open downpipe ands thats about it...

 

You'd probably be safer upping the boost rather than the compression. Cam gears do an engine good. Some guys pick up quite a bit of HP on the dyno with a turbo Honda using them.

 

well where do i start. you said mroe HP and not more boost. NOS. cam gears, cams, IM boost controller, bigger IC. bigger exhaust and down pipe. spark and timing. thats all tuning.

 

i could up the boost to 11 psi, but i can't go past 11.3 psi because of my map sensor i was told. i wanted to do 12 psi and keep it there, but i dont feel like getting the 3bar map sensor for 1 extra psi. How much hp gain would i get from 11 psi instead of 10 psi? from the mentioned above Hp and Tq....

 

those are some good numbers for a stock motor... i say don't push it, unless you have a spare car, but others will tell you differently i'm sure.

IMO...
don't mess with the compression
10psi on a stock gsr, is already a lot...

bigger downpipe/exhaust (3")
bigger throttlebody
intake manifold
headwork...
bigger intercooler
adjustable cam gears

look into bigger injectors too, 300whp with 440's seems kinda iffy.
and more tuning.

but it's all been said before.

who tuned your hondata for you?

 

you should just up the boost...adding parts cost money plus its still added hp so if your worried about to much boost, the extra parts making more power will put the same strain on the motor or will require the added fuel.

 

you'll have to get one eventually

 

Actually it's more like 9.5 or something like that is where the stock MAP starts to disagree with you. I'd sleeve it before you get too carried away with the boostin' high. Compression helps with spool and gives you more HP if you don't want to run that high of a boost level.

It's amazes me veryday when I hear all of your opinions. I wish there were people closer to me that shared the same interests. This town bites.

Lawrence from DSR in San Jose, CA tuned it for me in 30 mins. Rocket from ef-1 (formally hondasavers) made my base map...
