The B20VTEC discussion thread

[bennjamin]

My Old EG back in the days with a internally OEM B18cR motor with Intake, headers, exhaust and tune ran 13.6@103mph. This was on road tyres.

Power figures between different dyno's are irrelevant. 120kw from dyno A can mean 140kw at dyno B. The real result is on the circuit and 1/4mile. Track Times do the talking, dyno numbers are just to wank over

Just to add - I took my old Eg , same internally stock motor and only a jdm 4-1 header , full interior vti and re001s to a 13.7@103mph too.
Did 116kw atw but that's not relevant.

Point is the b18c r engine is a fantastic package and hard to improve on ( note tune and probable weight reduction do little)

Anyway.... Totally agree 1/4 mile / mph is somewhat of an indication of power and reliability. Factoring gearing and weight too !

anyone else apart from tb and Fatboyz taken a b20 vtec setup down the 1/4 or had some reliable times at the racetrack ?

here are a few good places to start playing with ideas:

Cheers man. They are awesome sites.

Benson and bennjamin, did you guys both run the ITR gearbox?

Cheers man. They are awesome sites.

both may contain inconsistencies - that is why i gave you both, use for 'ballpark' purposes only

TB when are you planning on taking yours to the 1/4? really looking forward to your build
Fatboyz, dave has built your customers lots of B20s how many of them taken it to the 1/4 mile?
Hopefully when i come back overseas end of October (if its not sold by then) ill get time to take it, currently have no licence

JSCC has a lane booked next week - so maybe then?

Lets not forget Toda built b18c 2L e240 motor. Not a bad motor. Similar ponies last yr b20vtec we had.

interested thread.
i ran a 13.6 b20vtec in my eh civic sedan vti model with no weight reduction back in the 03.
also a b20vtec in my dc2r with no weight reduction did a 1.12 around wakiefield park onthe old track back in the 04.
currently runnning a 1.8 lsvtec in my dc2r and with no time and testing after a fresh build raced it at the superlap.

Okay here is the situation, ive purchased a B20B8 from wreckers, looking at the PHK markings on it, when we took it home looked at the back of the block
it says P3F which is the low compression bottom end indication? but everywere else it says PHK on it, can anyone give us any idea on what pistons this block has?

someone correct me if i'm wrong? but arn't all B20B's the low comp (8.5:1, i think?) block's. and the B20Z's the slightly higher comp (10.5:1,?) blocks?

nah, the pistons designate the compression.

a b20b4 will have low comp p3f & b20b8 will have phk which is slightly less low comp...

never seen a B20Z so cant comment...

all b20b blocks i have seen are marked p3f externally...
