Stock b16a2 cams.

curves look good man,

no need to re-torque head studs - unless you failed to do it properly in the first place, then it is time for a new HG...

you need to find out where the oil is coming from - dizzy o-ring or the VTEC port on the back... either two places makes the oil run to the front side of the head...

PCV is covered in previous pages of this thread...

thanks tinkerbell.

Yeah, I checked the area under the dizzy and vtec sol and its definately wetter. Ill change the seals and see how it goes.

Also, I meant, would be be alright to run the oil breather to the intake before the throttle body instead of using a pcv. Could find any info on that..

[tinkerbell]

PCV is already covered, if you don't want to follow that - I cant really help you...

This.

I admire all the work, but for the $$ it took to build that motor one can dream of the K-swap that could have been done... I think it did a high 12 on the 1/4? Moiz can you confirm?

13.0 but that was his first time

There was an eg that made 160kw and ran a 11.9 on a stock 84mm bore b20 in comparison, I'll try get my mate who knows the guy to get slips and dyno sheets

What tyres was he running bro

one could have done 2 k swaps for what he paid. with oem reliability.

True that

ok, say i want 130kw plus b20vtec

i already have--- b18c7, mugen header, customized mugen twinloop (straight through pretty much) j's racing whale penis, hondata s300, spoon oil sump, hks oil cooler.

what kind of price would i be looking at? could i do it for around $5k using alot of the parts i already have?
im talking labour and tune included.

i was just planning to go toda b cams valve springs and retainers plus re-tune with my current b18c7, but im still waiting to here back from a workshop and in the meantime i've considered going b20vtec.'

opinions?

[GSi_PSi]

very possible. but depends on where you want the build done. people charge a lot of labour for a build in a shop , although Charlie at GPC is pretty decent
charges 800-1k for b20vtec build labour not including installation
B20 Block is cheap around $300-500 , wreckers will usually just sell you the whole engine
Bang for buck is RS machine which is basically ITR copies around $350 landed
Using aftermarket rods is optional as it is still n/a i recommend the stock ones are fine just shotpeen and press them into arp rod bolts $100
VTEC conversion kit $350
Bearing Overhaul kit $200 ( highly recommended)
New Oil pump $120

New tune ~500... calculated total around ~3k .... output power figure
same setup my cousin produced 133kw atw with toda header, 2.5inch catback with xforce twinloop, Injen CAI, Crome chipped ECU

[u mad?]

what would i be using off my b18c7? just the head?
is the spoon sump and cooler compatible?


thanks for the brake down of costs, makes things a little clearer!
