The B20VTEC discussion thread

**tinkerbell** · 19-07-2013 11:10 AM

hi ozhonda guys, look, i really appreciate all the "I was reading the B20VTEC thread and I want a B20 too!" messages...

but just to be clear:

1. no, i dont know of anyone in Sydney or Melbourne (i dont actually live there) who i would recommend to build you an engine.
2. no, i cant tell you all the parts that you need to build one yoursef, or how much it costs, or where to get it all from.
3. yes, i will consider selling my 160kW B20 race engine, but i doubt you could afford my terms.

im not posting this to be rude, but more so that you dont waste too much time punching out a PM to me that i probably wont reply to (unless you tell me that you just won lotto, or something... in which case i'd happily build you an enigine!)

People just want to over think there B20Vtec setups and dont listen to the correct people and read to much internet bull about what to do and what not to do,they like all Honda engines are not hard to assemble and if you build them as an OEM build with OEM spec's you will not have any problems the hardest part is finding a good machinist that wont tell you what he has been doing for years on cast iron push rod engines with 2 valves per cyl.

A small hint is find a machine shop that does machining for motorcycle engines because they know about TIGHT clearances because bigger is not always better they also understand how important balancing is with engines.

The other problem is tuning them with STD sleeves I just retuned one that came from a well know shop and is the 2nd one I have redone and it was WAY OVER TIMED and it was a very poor tuning job with only the 100% throttle done the rest of the tune was rubbish with very poor throttle response and it just drove like crap and the other tuner said thats just what B20's do.

yep, Honda engines are easy to 'put together', but you also need the right parts - and the right parts are the ones that are machined correctly, starting with the engine block.

to have a correctly machined block you need a great machinst, so take it to a specialist - not just a workshop that does bore an hones for grocery getters...

then balance, weigh, re-check and re-measure everything before it gets to final assemble, and you know that when it starts up first time you'll be checking for coolant and oil leaks, not where 'that rattle' is coming from...

then you shut it down, put it on a trailer and send to to your tuner for initial break-in and around 8-10 hours of tuning.

easy eh?

and 30'000km later you end up with something that continues to impress with big numbers:

Nice to see it come together after all your hard work Dave, let me know how it goes on the weekend bud. ; )

no worries mate, i am guessing people could contact you regarding the acquistion of a decent machinist service?

**INT DIST/TODA** · 24-07-2013 10:50 AM

Yes they sure will, we will have a full machining, cnc cylinder head and balancing service available to all shortly, just in the process of locking in a premises at the moment, whilst its been a slow set-up, rather do it right once! ; )
