I am a newbie to all motor so I've come here to seek ur all motor advice. I currently have a stock b16a in my civic HB. I have the chance to buy the crank pistons and rods of an ITR and also the head.

Im wondering what parts would i need to buy to increase my displacement from 1.6 to 18 litres in my b16a. Any help would greatly be appreciated.

 

well actually none of what you have the chance to buy.
unless you choose to run an expensive deckplated (raised height of the block) motor.

the ways you can increase displacement on your B16 is to
1) find a B17A1 crank and rods for a bump to 1.7 liters
2) sleeve the block and bore it to 84+mm cylinders for just over 1.7 liters
3) combine both of the above for just about 1.85 liters
4) run a deckplate which allows a larger stroke and rod and you can go pretty big displacement-wise but its not cheap
5) there was a guy here thathad a shop and ran custom rods and very custom pistons (and a crank possibly) to get a sleeved B16 to be 2 liters... not cheap either but very impressive

 

Bore x Stroke=Displacement...increase either one and thats how you'll increase your displacement. Unfortunately for you, the items that you just purchased (ITR rods/crank/head etc..) are not plug and play to your current motor. Except for the ITR head which will increase your compression but not displacement. Run a search and you'll learn a lot more.

 

It would be really expensive to buld that motor to anything more than a 1.8lt
What you shoud so is buy a B20 block and use all those parts you buy and use those on it (pistons, rods, head ) and then you will have a 2.0lt vtec (crvtec) that with your basic boltons and you will be jaming

Correction, you wont be able to run your ITR pistons on a B20 block...ditch the itr rods and use the B20 rods, should you decide to go this route.

 

oops i shall sorect myself, brain fart there for a second ! that is correct that u cannot use the ITR poistons in the B20 block due to the bore difference. But I would sure the ITR rods cause they are allot stronger then the B20 rods, if you want to use all the ITR stuff then you will have to get a b18 block (LS or something)
But I would still use a B20 and biuild it up a little. It will make allot more power then a bored and stroked b16 and will be cheaper!

 

What the hell just happened here?
1) changing to a type r head will not increase compression. He will see a minor increase in performance from increased flow.

2)The ITR crank + custom rods will bump him to 1797 cc's. All he would need to to is a little bit of machining to the pistons (they'll need to be notched, notching the block and oil squirters, and getting a set of custom length rods.
Even though it has less displacement, that setup would be stronger for drag racing, but maybe have long term reliability issues. You also might want to look at custom pistons with the wrist pins moved up (you wont need custom rods then, or you could run a combination of custom rods and custom pistons).
Anytime you're looking at something like this though, it is a serious job, and one that I wouldn't tackle myself.
IMHO the best way of stroking a B16 block is with the addition of of an Ls bottom end. You can use your stock Pr3 pistons, so the whole setup will be fairly cheap (compared to the project you are thinking of undertaking, but still in the thousands of dollars.)
I've got another post I'll find it later that'll really help you.

 

**** you'd be better off just buying an LS block and taking the B16A pistons out of you block, putting them in there and putting your head on.

Thanks for the help guys. I always thought that it was the crank that caused the difference in displacement from the 1.6 to the 1.8 motors. Having read all that, its more than just the crank! I think the best idea would be to buy a b18c bottom end (bare?) and put all the ITR parts on to it, and put the itr head onto it also.

Im not fond of the LS/VTEC setups, simply because the LS does not come with bracing/block girdle etc. Thanks for your hel[p guys, I know now that I cant increase my 1.6 to 1.8
