Why are you swapping a b16 for an LS? Are you doing an LS VTEC buildup? Please give us more information so we can help you..

lol...you would need a b-series VTEC head, definitly new pistons, LSvtec convo kit, and a tune to go with the new power. I'd also do a crankcase breather setup since ls/cr blocks don't have the shotty stock versions.

they make one or you can go with a cheap ebay kit which is the same exact thing (two SS lines and fitings and two dowels)

I just took my LS block apart that had some CTR pistons in very good shape, the guy that I bought the block from told me that the block had at the most 10,000 miles on it. I am selling them if you want em just let me know. Here are a couple of pics.

BTW here is a how to guide for a LS/VTEC build, hope it helps. http://www.c-speedracing.com/howto/lsvtec/lsvtec.php

From what I have heard any B series part will fit any B series motor. And as for the pistons they should work but if your going to swap out pistons why not go with higher compression pistons like CTR's or ITR's???

I used PR3(b16) pistons in my ls/vtec motor and they were great.

if im not mistaken ctr pistons are 100grams heavier than my b16a pistons no?
i remmeber reading that in some forum on here
it was comparing ctr pistons to another similar high compression piston

and wont i already be at alot highrer cr with LS/VTEC
around what cr will i be at when swap is finished with PR3 pistons
and around what cr would CTR or ITR pistons give me

are ITR and CTR pistons the same?(i think so but im not sure)

compression calculator



according to their calculator the PR3 usdm gives a higher cr than the ITR P73 usdm
it gives around the cr same as ITR P73 jdm
however it the cr of B16 P30 jdm is quite a little bit higher than the PR3s

with that information wouldnt it be wiser to just stick with my pistons rather than buy new ones that will give less or same cr

unless CTR pistons are PCT pistons ? in which case they would be higher cr.

thats what i figured
because i read somewhere that raising compression by a larger dome wasnt very good
(i could be wrong i just remember reading it)

and 2ndly where could i purchase a 2 layer oem gasket or is there a better gasket i should get

OEM headgaskets are 3 layers; people usually take the middle layer out to get a little more compression. But you could buy a Mugen/Spoon headgasket to raise CR, or do the former, heck I've heard of some using only one layer from the OEM gasket.

BAD NEWS

well the reason i was doing lsvtec was because i couldnt sell my b18b1 engine (full swap)
today a man knocked on my door around 12ish noon and wanted to buy it and take a look at it.
well he comes monday to pick it up. i cant decide wether im happy it got sold or sad because i cant do the conversion now which i was really looking forward to doing. i just wanted to thank everyone for their help as i was preparing to do the swap yet cant now. however i still plan on doing the conversion in the future so i will keep u posted as to when i get a b18 block again.

well thanks the info helped alot
