B18c crank rods and pistons??

[D'janiero]

I'm hoping to start collecting parts pretty soon to stroke my b16b.

I was just wondering how much roughly I should be expecting to pay for a b18c crank rods and pistons?

Also how much would I get for my b16b crank rods and pistons?

I'm still in two minds whether to use b16b or b18c pistons (Ive heard b18c pistons are better, as their domes are not as prone to hot spots like the b16b??)

Thanks guys

Expect to pay around 700$USD + for the combo.

B18C are not "better" pistons, B16B are good pistons also, the problem is that if you install B16B pistons on a stroked B16B you will raise your compression to 12.1+, you'll need, high octane fuel, programmable ecu and a good tuner because your car has a big chance of suffering from detonation

Point taken rvm
Tuning on hondata s300 is something I would like to do in the long run, not straight after the build. So I think I would be better off using the b18c pistons so I can a b18c ecu untill I'm ready to go for an s300.

Would their be much difference performance wise using the b16b pistons with higher c/r opposed to using the b18c pistons with the lower c/r?

You'll have more hp for sure, higher compression (with good tuning) = more whp. Also you can get bigger cams, for example skunk2 pro 2, to match your compression ratio and get some nice whp numbers.

If you use the B18C pistons you'll have less compression ratio but you car will not need high octane fuel, and you can easily use it as a daily drive car.

Make your decision based on what WHP you got in mind.

Any B18C (stock or modified) is always ready for a Hondata S300 since oem honda ecus, are made to pass emissions, fuel economy etc. Hondata S300 is a "perfomance wise" ecu

the PCT pistons have high dome that rises CR but don`t have pockets, and piston to valve clearance will be an issue, especially when using more aggressive cams plus you`ll have detonation timing issues.

I'm not after big whp really. I would be happy with anything between 180-190whp
I have access to 99 ron fuel over here, but I think I will go with the 18c pistons as I'll be able to use the stock 18c ecu untill I'm ready for hondata.

Thanks for the info. I'm sticking with 18c pistons

If planning to tune the car in the long run, I would stick with the B16B pistons and simply put a thicker head gasket to get the compression down to safe levels while being able to use the stock B18C ECU.

So that when the time comes and you decide that you want some more power, all you need is to replace the head gasket and get the compression back up which involves much less labour than replacing pistons! As stated earlier, a good tune is a must in this case.

Guys, how can I tell the difference between the b18c/c6 crank pistons and rods, compared to those from a b18c4 /B18c jdm si?

ps -Hey Fonzu. I see your point, but I would'nt feel comfortable running that setup with a stock ecu tbh.

My crank rod and pistons may be up for grabs as i might... might.. be going B20 will no by the end of the week.

 

[D'janiero]

Orrr don't say things like that to me man. I was thinking about maybe going b20 after speaking to daz81 a couple of months back. You've got me thinking again after saying that dude lol.

I know daz81 and others say that a b20 can rev jus like a b18c (if you a b16b/b18c head) but in the back of my mind I would rather have a b18c as it was made to rev from the fatory rather than having to add parts to make it rev safely if you get what I mean Ian?
Having said Ive never owned a b20 vtec so only can go off what others have said. b20 vtec must be alot of fun though man.

hmmm....got some thinking to do

 

[Gee]

Unless you have a reputable builder who knows what the hell he is doing I'd stay away from the B20 conversion. Very unreliable if not done right (from my research)

 

[D'janiero]

I hear you Gee. If I did go b20 I would be getting someone like Daz to build it for me. He seems to have a good rep building reliable b20s.

I might just play safe and stroke my b16b as originally planned. I'm hoping maybe to go turbo next year if/when insurance allows (either that or buy another starbo lol) so sticking with a stroked 16b seems to make more sense.
