    B18b Turbo & B18c2 Turbo

    theres this thing on these forums going around where people saying the b18b block is stronger? eg: to support turbo. can anyone provide hard evidence to support this case?

    need to know, so i know whether i should get dc4 gsi or dc2 vtir. (eventually turbod t28) bang 4 buk wise.

    any proffessional advise could be helpful!

    I think one of the limitations that was mentioned was the fact that the VTEC head will flow better than the GSi head ?
    Got a question? Check out the FAQ - http://www.ozhonda.com/go/faq

    but is the b18b head restrictive in anyway?
    or it just doesnt flow as good as a vtec head with normal atmospher pressure.
    remember the engine is no longer sucking air in.
    do the same pricipals apply to a boosted motor same as a N/A???
    vtec was designed as a means of getting the most power out of a small capacity motor with out the need to boost, so y go and boost it, y didnt honda bring the option of a boosted vtec?
    these motors make great power NA thats the way they were designed.

    I wouldn't go as far as saying it's stronger... most people claim that because the b18b is lower compression

    yes, i always thought that ppl chose b18b for forced induction because of the lower compression too

    i could be wrong...

    well ill be getting internals done too, so it wont make a difference will it? strength wise. or heard flow wise? or is the vtec head still an advantage... turbo vtec'

    fly have a search on the net to see if the vtec head has an advantage under boost to the b18b.
    i have been told i doesnt by 2 tuners.
    i was all set to buy a recon flowed b16a head for my gsi, but i back off after speaking to these blokes, they said the difference it will make would not be worth the price,
    boost and vtec are 2 different methods of extraction max power out a small capacity engine.

    if you look at cam specs then you will c the difference between a cam profile designed for a turbo motor and 1 for max N/A power the duration @ .050" is a lot lower on the turbo cams on non vtec vehicles.

    i been told the b18b is much safer to turbo and in the long run you will get more out of it

    Vtec seems to limit the amount of boost you can run, assuming both gsi and vti-r engines would get new internals, the vtec cam profile would be to high to run higher boost, end up with valve float in high rpm
