** LS Vtec / B16a2 + B18c Block **

[Twincam16]

Info:
B16a2 motor

If I want to add .2L displacement, what will I need and what options have I got?

Please no talking about B20, K20 or H22's

Ive been reading that getting a B18c block will make me lose compression. What can I do to get around this (on a budget).

Thanks gents

not really an ls/vtec, setup you mentioned above is "Poor Mans Type R"

the other alternative is to use a B18B block and use the pistons from B16a to get the compression up... block won't be worth anything anyway...

but AFAIK B18B doesn't have piston oil squirters and finding a B18C2 block is the most hassle free way to do it.

Couldn't you also use CTR pistons to get Compression raised?

or is this only in the case of a B16a2+B18C7?

i posted this before but fell on deaf ears.. probably should've ended up in the faq:

really good calculator if you know the aus specs to punch in...

CTR pistons are ideal for anything but a B20 for obvious reasons.

but regardless what block he chooses.. using the standard B16a pistons is still better

the piston and useless B16 block after build is probably the only reason i'd pick a b18b over a b20 build though with 1.6l equipped cars as it also doesn't need to be engineered (under 15%)

From what ive heard, b20 route would be just too expensive. Funny that my mum has a crv though... so might happen one day (*evil grin*)

Correct me if im wrong. Cheapest and hassle free option would be to go B18c2, retain b18 rods/bolts & switch the heads and use my b16 pistons? Will this lift CR back to normal?

*Any issues with timing?
*What ecu?
*Anything else to consider? There is no difference between the hydro box on B18c (apart from r's lsd 6spd) and a b16a2 box correct? So should match up no trouble

have a look at some of the b20 builds, they are not that expensive, pretty much the same cost as your b18c with a b16 head.

Also no 6spd in b series. :)

all b series box are interchangable

Ignore my moment of retardation there... lol

Except itr has LSD option correct... What about hydraulic/cable? No differences?

cable gearboxes came on the older OBD0 series of cars afaik... shouldn't even be an option for you.. FD is different if you get the 4.7FD itr box.:thumbsup:

play around with the calculator though...

the way i see it assuming you can get a b18c2 block for $1k it'd be the best combination of hassle free + easiest + cheapest in the long run... hence why so hard to find

I wouldnt go thru the hasssle of swapping heads over. Just change the whole motor.

What is your budget?

Jimmy, whats point of getting b18c7 if ive already got basically the same head?

hassle?

Do you actualling have the same head? ITR has better valve springs, cams, valves, and slightly better flow. Not to mention ITR manifold and 62mm t/b.
