im planning to put CTR pistons in my 1st gen B16A, juss wondering if this set up is safe for my motor. if i do put them in wat grade of gas should i use??? 100 octane??? will there be any valve-pistons problems???

i need all da help from u guys....so if anyone have tried this set up b4 pls let me know!!!!!
THANKS!!!!

 

I use it right now with head milled 20 thous and run 93 Hess fuel... no ping.

ive got a milled 40thousands on my head.. and ctr slugs using 97 octane petrol no pings watsoever.. when i go lower than 97 i can hear ping on accelration...good luck dude!

 

i had them in my ooooold b16. no problems on 92+ octane. head was milled minimally. no pings, had remapped ecu with nasty fuel curve though.

 

would i have any problems running os ctr pistons in a b16 on 91 octane?

thanks

 

no, the lack of displacement in a B16 makes it fairly safe. The CR is much higher in 1.8's and plenty of people are using that setup with relative ease.

 

just to be more accurate, it is not the displacement per say, it is the relatively small bore that allows for high CR on B series. and very good chamber design.

so its all good....it should be fine...pump gas here in australia is 98 octane. ill be runnin it with juss da normal b16 head with SPOON thin head gasket and ITR cams.

thanks guys!!!!

 

not a problem whatsoever....good choice, but don't forget the milling on rod end so you will fit (about 1 mm total taken off width) piston.

 

isnt 1mm both side of da rod end????

 

Yes just one millimeter off both sides. But I will say that if you are planning on running a Spoon 2 layer head gasket you might want to reconsider. A lot of people have been blowing them, the Mugen piece seems to work a little better. Either way good luck man...sounds like you have a really nice setup on the way.

 

yes, here's a diagram to help you understand what needs to get milled:

 

thanks dude!!!! i hope everthing will work fine.....i should be ordering my CTR pistons in new zealand pretty soon......

 

HEY CHIE how much are those slugs gona cost u over there?

 

560 new zealand dollars...dats around 500 australian....and dats about 12500 philippine pesos!!!! is dat cheap???? its brand new from HONDA NZ.

 

that's about 260 US, that's a grip, unless that's with rings.

 

Katman, completely OT, but i have to ask, due to the fact that i anticipate the reopening of your site for a while, i trace back the pictures you post to their respective parent directories . the questions is, how the hell do you keep your engines so damn clean?!

i guess the pics are decieving for some of our engine bay pics. Just wipe it down with a rag & cleaner...that's about it.

 

thanxs guys
