BTW, you read some forums and never saw the RLZ flowcharts where an LS with a valvejob outflows a stock VTEC head? Sir, the ports are the SAME SIZE as a VTEC unit. The bowls are a bit of a disaster by comparison, but can be opened up. There are OEM 33mm intake valves For people wanting to make more than 200 whp, which is the reasonable cutoff point for a stock valve LS head. You really should sit down with a 92+ large port LS head sometime and compare it to a VTEC unit.
Maybe you are right, but vtec heads still have an advantage imo, who wants to run huge oversized valves, high c/r pistons and high lift cams? fuck p/v clearance issues, v/v issues and after all that you still have worse gas mileage and premature rocker wear because you are constantly on a big lobe, and still making only similar power to a more low key vtec build.
I don't know where to begin?
I never mentioned huge oversized valves. You aren't getting power out of a VTEC motor without high CR pistons and high lift cams. ?? Never had p/v issues with any mild up-to-12.5:1 CR Honda motor, and the only thing I've experienced valve to valve problems out of was a VTEC head, sorry. A stock LS swap gets 27-30 mpg, and Wes was getting 30 mpg off of his B20 with 272 and B16 trans, and 31 mpg off of his LS with 403 setup and B16 trans. Never seen premature rocker wear out of anything except a B-VTEC and H22, sorry to dissappoint - we aren't dealing with a big heavy component cammed V8 that got fucked in the ass when all the suphur and zinc was dropped out of the common off the shelf oil supply, when those guys started stripping out cams shortly after the millenium, the import guys didn't know anything about it.
How do you explain needing to run 33mm valves to break the 200whp mark? when there has been many vtec builds making 225+ with 33mm stock valves
...
Do you even listen to yourself?
