ARP bolts & studs

Top End
96 VtiR head
Bronze valve guides
Valve Job
New Valve stem seals
Dual valve springs, titanium retainers, flat faced valves & seals.
Full port and chamber work w/ competition valve job, resurfaced and assembled
BC Spec 4 camshafts and toda cam gears
ARP bolts & studs

Tranny
Type R gearbox with final drive
Fidanza lighten flywheel
Upgraded clutch

Other shiet
Hytech replica 4-2-1 header 2.5 inch (looking at upgrading)
Skunk2 intake manifold
Hondata computer
High flow injectors
65mm throttle body (looking at upgrading)
2.5 inch CAI (looking at upgrading)

anyone recommend any good tuners?
Dyno Dave was my man but ive heard he is retired?

what sort of power and 1/4 mile times do you think ill be running with street tyres, stripped out back seat, front seats and boot upholstry all gone?

im hoping for a 13.2? would that be reasonable?

Adrian from Toda is what I hear

What chassis?

[booget]

Dc2 chassis

yeah mid-low 13s high 12 is possible with this engine combination provided its not a lemon
and makes power on the dyno

In comparison a 158kw B20VTEC DC2R did 13.4@105mph 2.2 60FT on street tyres.

maybe up the final drive as well to 4.9?

[booget]

do you guys think i should get a bigger throttle body? bigger CAI?
or even go a 3inch zorst?

[Super-DA9]

I'd run a 68mm without hesitation, especially for 2.0L displacement. maybe an Injen or something similar to go with it as they are something like 68-70mm. and get the opening in the S2 manifold machined out to match the throttle body size.

I personally wouldn't bother with 3" exhaust on B series unless you are equipping it with forced induction. 2.5" should be plenty, or maybe 2.75" at the most.

Right on.

thanks for the input guys.

i think i will go bigger CAI and throttle body =)

cant wait to thrash the bloody thing.
waiting on the joint oil cooler part from overseas since I cant find one locally

[GSi_PSi]

Before you go about thrashing, be sure to get a breather system made up, to let out all the excessive bottom end pressure the vtec head will stress on the
B20 Block.
