I have a jdm b18c its dynod 179.4 and 128 tq on a dynojet. I was wondering if you think 200whp would be possible with the stock bottom end. My mods consist of skunk 2 obd1 harness, no p/s, just put the a/c back on(dynod with no a/c), no cat, JDM R header, greddy sp header back exhaust, AEM type r CAI, STR 70mm throttle body, port matched skunk 2 manifold, CTR intake cam, B & M fuel regulator(52 psi) stock injectors, msd 6al, ngk plugs and wires, AEM adjustable cam gears (still at zero), Spoon flywheel, ACT heavy duty six puck, tuned with a VAFC on a stock jdm p72.

to hopefully acheive 200whp i was thinking jun 3 cams, port and polished head along with milling to up the compression a little, tuned with hondata, and tuning the cam gears. And add some ground wires( i believe the propaganda) and hondata IM heatshield.


what do you peeps think?

 

Not to sound like the ***** of the board....

but i really doubt 200+ would happen without higher comp pistons and maybe milling.

 

i said milling if you would of read it
not to sound like a ***** on the board.... i know big cams like compression i just want to know if you think its possible with a stock bottom end 200psi. and if anyone has done it

hey Mr. Teg tried to see wuts up with your ride but couldnt access it
said to try back in an hour or something cause it was down or something

dude you asked if 200 whp was possible with stock bottom end. I said no. Regardless of whether its milled .50 or not (which would be impossible with big *** cams because the pistons would murder the valves).

haha 200 psi.....

 

i dont know what the hell you are talking about, but 200 whp is waaaay dooable on a JDM B18C stock bottom end... ESPECIALLY if we are talking about the spec R B18C...

Its going to take some more work... but it is possible with a GSR C... First of all.. it seems as though you have thrown away a lot of your money thus far... i mean.. i dont remember all your mods but your MSD???? 70mm TB???? Why? anyways... here is what you need

1. GOOD exaust manny... look header tech, hytech, ANR, SMSP..
2. 2.5 mandrel bent exaust w/ high flow cat or test pipe (prefer the high flow)
3. 3 angle valve job and p&p head... working up the head makes a big difference
4. Some decent cams.. My prefrence is Toda/Skunk either the Bs or stage II
5. I forget your intake but you need an ITR manny (skunk 2 replica if you have a GSR)
6. Good intake.. id go with Jay's Racing CF short ram.. very succussful
7. Cam gears and vale springs that are made form the same manufacturer as the cams you are buying
8. Engine management.... Hondata s100 would be nice.. but you have a VAFC and that should get you started
9 Possible bigger injectors depending on what your dyno shows... but most of the stock injectors will be running @ 100% in the upper rpm ranges for the power your looking at.
10. About 3-400$ for dyno tuning..... This is VERY important, and goes missed by alot of people..

With what i have given you... you should be right around 200 for a stock GSR stock compression, and over 200 for a 11.1 stock comp for a JDM B18C spec R...

You can mill a bit with the stage IIs and B's... so dont be scared just remember to advance the timing accordingly to compensate until you get tuned... and if you want to be ****, clay the motor before hand just so you know how low you can go...

hth

 

just reread your post.... if you are pushing 179.4 right now.. im thinking you have spec R... you will get 200 whp no prob.. i currently have a 96 B18C spec R that i have dynoed at 176.5 with nothing more than an pos intake, pos exaust, chipped P28, and gears...

Bought the motor this way, but i have personally seen many a type R stock bottom end do exactly what you want to do... and you got more comp to boot...

 

im making a bit over 200 on stock USDM b18c5 block

 

im going to make over 200whp on a stock jdm gsr block. Im at 182/131 right now, and my header and IM gasket are on the way. PNP and a mill and im there so who wants to help me pay for it?

 

A few key things that I see being reciprocated here that are good points...

1. --Cams--
Big cams definitely like compression. The more compression you throw at it, the better results you'll see. However, milling the head and throwing some big cams in there im not sure is your best option. You might have a problem w/ the valves.
2. --Headwork--
http://www.portflow.com

3. --Valvesprings--
Toda valve springs seem to be the sure bet. They can handle cams with alot of lift....safe to rev to about 9500 or so...

4. --Header--
This is key....you need as much flow as possible...(SMSP etc)

5. --Tuning--
Hondata and some injectors+dyno time and a good tuner=success.

Ive seen almost 200 whp from a completely stock c5. (no mods internally)

I dont think that 200 whp for your goal is out of reach. Good luck

 

thanx for all the input guys

what about valve to piston clearance, right now i have a ctr intake cam( ive heard thats a little less lift than a s2 stg 2) i have the skunk 2 manifold type r replica so yes it is a jdm SIR NOT a jdm SPEC R compression is around 200psi with a compression gauge so i believe its around 10.8:1 maybe less. If I were to get JUN 3's would that be too much cam for the stock block? Would milling be out of the question with that big of a cam? Ive heard of this clay procedure before but not exactly sure what is done.

 

Don't worry john you'll be there soon.

back at you

 

inlinefour.com had an employee nammed kenneth that had a JDM b18c that knocked out 205 to the wheels on JUN3 cams and PYR headwork. so YES. it is possiable.

Aslo MAX ha made a bit over 200 on a USDM b18c5 with jun cams, last year.

so thats 2, not only is it possiable, its been done.

 

thanks for all the input guys, thats definitly what i wanted to here, i didnt want to mess with my block yet since its still running strong. what kind of fuel management was max ha using by any chance, VAFC? Hondata? what was his torque? ive see high hp motors with not that much tq, not that it matters anyway just wondering.

 

I've seen people break 200wHP on stock bottom end in their usdm b18c. It's doable, no doubt.

I want to see proof of that.......

 

try importreview graynayda

 

Miguel SIINS made 205whp and 136TQ on a stock B18c itr bottom end .with jun spec 3 , header , jun ecu and bolt ons . So is possible depends on the type of cams and tuner

 

damn gaynayda sun seems like your being proveen wrong again
maybe in maine they dont have experienced tuners

 

its granada u illiterate bast. ask me if i care about being proven wrong. at least if gets you mawfuckas to post.

 

I made a little over 200whp & 153tq on a stock usdm b18c5 block, JDM type R header and VAFC for tuning. Definatley possible.
Good Luck!

 

153tq from a 1.8 thats internally stock? Eh....i dunno about that man.
