The B20VTEC discussion thread

no, sell teh B18CR short block to pay for the B20...

it will cost you around 5000 for a built (forged) bottom-end...

plus 89mm crank is better than the 87.2mm crank for power...

is this considered an average price? sounds quite good considering all parts/labour and warranty from TODA.

[MikeyG]

its a good price coming from toda, obv theres some that can do the same for cheaper but you dont know their workmanship

[grifty]

how much kw can the stock crank handle?

[ZeForce]

More than you will ever make naturally aspirated

Yeah im talking with Adrian ... So many different directions..

lol -- anyone want a B18CR engine un-opened? What do they go for? 205 compression approx across all four cylinders.

Spreadsheet is looking a little crazy with all the different cost scenarios argh...

Adrian --- Thanks for your time again, always plenty of time to discuss with your customers!

Great site on how to build a B20 -- With actual example measurements for machining etc and detailed instruction ...... Hmmm ...

Yeh Larry does a good detailed build report, there is a few more out there on honda-tech, I take some of their advice with a grain of salt though... gotta remember the politics behind it all, it's very annoying.

ivé had a b20vtec for 3 years now built from the bottom up. you name it, type-r crank and low friction journal berring's , 84.5mm forged 13 comp pistons with 3 leaf head gasket to drop the comp to 12.5, forged rod's, block guard+welded in and the block planed and the cylinder's honed out, p72 vtec head, stage 3 + buddyclub cam's, skunk2 intake manifold, buddyclub 4-2-1 header, high flow cat with 2.5 straight through piping, toda racing fly wheel, exedy sports tuff clutch, type-r gearbox 4.7 final drive, koni adjustable shock's with lowered king spring's, blox 68mm throttle body, buddy club double coil valve spring's with titanium retainer's, jdm p30 ecu with apexi vafc2 and 240cc injectors. and this is my daily to and from work ,shop's, road trip's and home. iv'e had no problem's with this set up. it was buit @ good performance centre yennora by charlie and his crew. so why doe's everybody hate on the frankenstien?

You spent all that money, and tuned on a VAFC2?

What sort of power you getting from that combo - Imagine the header is restrictive? I've heard restrictive header can induce detonation in high output B20's?

Stock ports on the head?

I'm about to buy an Endyn head thats been prepared -- 1mm oversized intake valves, extensive porting and welding etc .. Hoping to use it as my 'power-getter'

[ewendc2r]

Thanks for the info -- Also wondering why you went with 13:1 comp pistons only to reduce comp by using thick head gasket.. ? Were there clearance issues?
