has anyone try this before?? What compression ration that will be??
And how much power and torque it will produce??

 

This has been answered a few times recently...

You will need B18c rods in order to properly use the B18c crank. If you use the B16b pistons you should have around 12.1-1 compression.

Power and torque is subject to tuning.

HTH

 

why i cant use da b16b rod? i thought those two are the same... ???

 

I'm not familiar with the B16"B" rods but B18C rods have a smaller big end width than the rest of the B series. I'm assuming that the B16B rods have the same bottom end width as the B16A/B18B/B20B/Z.

 

I think the B16B has the same size big end. The rods are longer than the B18C rods though, and so I imagine they will not fit.

 

the compresion will be around 11.6-11.8. after all... it has the type-r head. if it had the gsr head, then it would be about 12:1

 

oh.... and the gsr has a longer stroke so it uses shorter rods...

 

oh.... and lots of power.... i got a gsr crank in an ls block with ctr pistons.... which is the same think... and its well worth it. i got a milled head too so my comp is higher. i say go for it.

 

The easy way to think about the B16B is that it is a B18C/1/5 block with a B16 crank... To make up for the additional 7mm taller block (over the B16A) you have to run a longer rod... That's what gives the CTR motor its ~1.86R/S... When you drop a B18C (87.2mm) crank in you have a overall stroke which is 9.8mm's more than the B16... That means at TDC your piston will be sticking out of the block ~4.9mm's... NOT GOING TO WORK... That's why you need the B18C rods... They are set up for that crank and block deck height (270mm's)... With the P72 cylinder head as everyone has said at std. bore your static C/R will be right ~12.05:1... If you have the CTR/ITR/B16 (PR3) cylinder head you can take off roughly 0.20:1 dropping you down to 11.85:1... Remember longer stroke means more air compressed in the same combustion chamber volume for more compression... Likewise an LS motor (89mm) crank will yield a higher static C/R with the same basic setup... Hope this helps... Latez

 

thanks a lot guys....
need to do experiment now...
