I really need your opinions and experiences on this so please help me out. First, im driving 94 eg(dx)-D15B7 with about 250k on both enging and body. I decided I'm gonna do a swap this coming summer and put a B-series. I want to get the engine before summer so that I can replace timing belt, water pump etc.., before summer comes. This is my project this coming summer and looking forward for next year, TURBO ... My first choice is B16A, so which one is the best to boost. Need your experiences here and opinions. Thanks guys!!!

i think the b18b has less compression I think... which would be good

2civic3

how much psi can you run with B18B??

littleblue

I've seen some guys running alot up to 30psi and im sure there has been a higher number, it depends on the mechanical components and how well you tune your car.

b16a turbo. thats what i have. since i have put it in i have never though about getting a different setup

Id say get the B18... lower compression and you get the torque you want with it. My buddy has a daily driver on 11 pounds with 267whp

the b18b is lower compression and handles boost well, my friend is going to make 275 whp on his ls motor with stock internals. B16's really do not have much torque to them so I wo uld not recomend buying them, I have not been impressed by a stock on yet. But there are alot of people around here running bosted b16's so they must handle it decent, have not heard any horror storys just know the ls is a better boost motor

haveaniceday

everyone is going to be biased .. you have to decide what you want .. i say ls/vtec best of both worlds .. if that isnt an option, b18b it is ..

can someone post a Dyno of B18B boost here?? thanks guys for the ideas!!!

I probably can but it's not on stock internals.

You definitely want to go B18B if you're going boost, the bottom end is stronger than the B16, and with good tuning you can make respectable power on stock bottom end. The only positive aspect of boosting a B16 is VTEC, otherwise the engines have low torque. If you want VTEC, just go LSVTEC

B18b that would be my choice. That what I have planned for my car.

TheThiefTheKnife'NTheGun

I am all about the vtec with boost. If you have to choose between the two of them I would go with a b16. But that is just my opinion. Yeah the compression on the ls is lower which means you have a bit more room for error but if you have a solid tune you can run higher compression with out blowing up..

2civic3

so how much HP can you make with B18B non-vtec stock internal with boost??? good feedbacks guys, peeps here rocks!! thanks and keep coming....

DYRcivic

if you really wanna go cheap get a d16y8 SOHC or any Sohc vtec and boost it
go here if you want some more info

not planning to go back to SOHC yet(no offence SOHC fans). just wanna feel DOHC with boost then get another civic 4 door next summer and boost that sohc....

a STOCK b16 blows at 26 psi

I'd say with a good tune you could make 250-300, but it won't last forever that way.

^at least b18b's are cheaper then b16
id say go b18

That would probably be your best choice. I'm going to boost my B16 eventually, but my car came with it, so.... meh

Yeah you couldn't be more wrong...have you ever seen the internals of either motor?..b16's are built considerably more stout than an LS...b16's have shorter, thicker rods and bigger rod bolts, and being a shorter deck motor with a shorter stroke, the sleeves are less likely to shift..the only strength "downfall" is the higher compression ratio, which means tuning has to be more precise to avoid detonation, but the pistons themselves are not physically any weaker than an LS.Either motor will take 275-300whp with a good tune, you just have to decide which powerband you like, torque or top-end.

I disagree. Have you ever compared b16/b18 rods in your hands? B16's rods are hands down stronger. That and the fact that the longer stroke puts more side load on the rods.

All that aside, I would personally start off with a LS turbo over B16, haha

ITS_Dunn

I sold my full jdm b16 swap, bought a full b18 swap with the cash and had lots left over, that includes my new act clutch i ordered for it

Im sticking with the b18 for lower compression and torque, nothing compares when you have torque imo.

as for vtec, i find it pretty useless when turboed, as well, if you are wanting just the sound, trust me, vtec is pretty much gone when you boost plus, all you wanna hear after is pssssh

TheThiefTheKnife'NTheGun

That is not true about vtec.. If you look at any dyno plot with a vtec turbo motor when the car pops over into vtec the HP just jumps.. Vtec isnt just a sound..

vti2

On the street a build B16 will allways beat a B18b because it has less torque at the bottom end so yoou will have more traction.
And yes vtec is imo better, und can get more WHP with it because you are getting more air to your cilinders and you can also rev it higher so you can use the powerband from a big turbo.

ITS_Dunn

true enough, never really thought of it that way.

i assumed that the dyno showed that there wasnt a jump when vtec kicked in, i always heard that it was still just as constant.
