Hello,
I blew my B16a2 block, and now I have to build a new one... The head is fine, and I am trying to buy a C5 Block but not enough money for that.. I checked with Bert-O and New is 2100 plus tax.. anyways, I think i am going to get a bare b16 block..

My question is.. What internals would be nice to use???

I know that I really want to use CTR pistons, (I believe they yield a 12:1 Compression, correct me if I am wrong).

I do NOT know what else to do as far as; Rods, Rings, crank (Knife Edge, etc...) Block gaurds (I think those are for Turbocharged motors, not sure...)

I want to make a great bottom end, and the head I will be using REV Valvetrain (Stainless Steel valves, dual springs and retainers..) with either CTR cams or TODA Spec B's, and a port and polish, not sure about angled valve jobs...

I just don't have much knowledge in bottom ends, so any N/A suggestions would be much appreciated..

Thanx

You should hook up with a good engine builder unless you want to "learn" on this build.

SGT or RLZ is not to far from you.

Hopes this helps.

 

i think ctr pistons will not yueild 12:1 on a b16. can anyone confirm or deny this?

u might wanna build a b16b.
custom length rods\find ctr rods and throw a b18c crank and ctr pistons in

 

CTR pistons in a b16 are around a 11.5:1

CTR cams are 11.5mm, duration 243 @ 1mm intake and 10.5 mm, duration 235 @ 1mm exaust Not to bad of a cam set.

Don't touch the crank. Stock honda cranks are almost perfect.

Only other thing you would have to do on the lower end is have the rods shaved for the CTR pistons.

On the pin (small) side of the rod you would have to take 1mm off each side of the rod.

 

SGT or RLZ???? Not sure what you mean????

i think ur best bet would be to buy a bare b18 block and put ctr's in that block...ull be much more happier with the gains u will see..like a b18c or b18b block would be fine

 

**** a c5 block...it's not worth **** to you if you want to run the CTR pistons anyways

bet a b18c1 block or a b18b/a or a b20b/z

get a hold of Brad and get that thing running

 

I have had a stock B16a block with Type R pistons and Jun 3 valvetrain. I was very dissapointed with the end result. I like to make lots of torque and a B16 is really hard to make torque with. Are you trying to build a drag car or a roadrace car? That I would need to know to give you my best advice.

 

well before u do any thing what happened to your b16 block is it still in 1 piece or did you blow a rod out the side? what kinda power are you trying to make? street drag ? give us a call we can help you out the number is 310-328-5514
or check out our web site and go from there maybe you'll get some new ideas

The block is no good, No.1 cylinder rod ripped thru the front and rear of the block.. I would like to make a road race car... I like highspeed cornering and even quicker apex exits... I'm not too big on racing from one red light to the next.... just gonna get myself more tickets that way..

 

i say just save for the b18c5 block. but if you really dont wanna spend the money, get the ctr pistons in a b16a. the CR IS around 11:1, give or take.

 

Why do people say "do not touch the crank"!!! It may be almost perfect but that does not mean that the bottom end will be balanced with the rods and pistons etc.... Oh yeah and in the racing world, ALMOST is not good enough. An ALMOST balanced bottom end turning 9000+ rpms will usually not be good enough.. Sorry I just had to let it out cause a lot of people talk about the "great honda crank".

i hope u have jdm itr pistons becuase usdm itr pistons loose compression in the b16

He had CTR pistons.

I think they mean dont knife edge the crank not "don't balance it".??

 

Yes, balancing is always a good thing!! But knife edging, cutting, welding and grinding to make a stroker are all bad.

 

why do ppl want ITR blocks???

it's the same thing as the GSR...but cost more money!!!

the only difference is teh tranny to block stiffing thingy...but who cars...it's basically worthless


just get a GSR block with eagle/probe/of the cheap *** crowers...toss in some 12.5:1 pistons...BALANCE IT ALL, including the clutch and flywheel...and be done with it

 

Its not a bad idea to take weight off the crank. Especially if you make the counter weights equal to the rod and piston weight. Enertia should not be lost given that you do not take off more weight that would exceed the weight of the piston and rods. I am still a fan of knife edging the SOHC motors!!! haha

Counter weights aren't for counter weighting the rods and pistons, They are for counter weighting the bearing race (part on the crank that the rod bolts to). The crank should be balanced to itself, flywheel, and pully/harmonic balancer. Rods and bearings should be weight matched to the other rods and bearings. Pistons, rings and pins should all be weight matched to the other pistons, rings, and pins.

If everything is done right the entire lower end should be perfectly balanced when put together.

That's fine and dandy, but I have yet to come across a normal condition crank that is out of balance. The crank out of my LSVTEC I built a long time ago couldnt be any more in balance according to my machine shop, aswell as the R pistons I had. This is just one example, I certainly HAVE ran across many other cranks in perfect balance.FWIW
