Alright i am running a Stock B16b CTR motor in mmy hatch, besides the bolts ons, i wanna go Toda Spec C cams but not sure if i will need there pistons, i am pretty sure there pistons and CTR pistons have the same clearance, but not postive, adn i was wonderomg if anyone here has the Toda setup on there car, Cams, Springs and gears.

 

hey if u r gonna get the toda cam r u gonna sell the ctr's if so how much r u gonna sell them for???

 

sorry man its already got a owner if i get the cams, buddy is buying them.

 

BUM BUMP


come on guys i need some help here

 

to get the most out of the cams you will need more compression

Definately.

 

I agree 10.8 compression is not enough for the Spec C's. Need at least above 12.0 compression to make the best use of the cams.

Got a similar set up as you with Toda A's, Toda E/M, Toda cam gears, Toda valve springs, Skunk2 I/M, Skunk 2 retainers, RSR test pipe, JUN Hyper exhaust, JUN clutch & flywheel, etc.

When I spoke with some tuners in Japan, they recommended 13.0:1 compression for the Spec B and C.

 

you have a b16b with CTR pct pistons....the highest bseries compression piston honda makes.....

C's will work great!!!

get some head work.....mill/deck the head and run a 2 layer headgasket!!!

my b17 on C's put out 197 and 124!!!!!

with ctr pistons.....

 

what head gasket do u say i should use...and soo all i will need will be the C cams and Cam gears and springs right....

THIS IS NOT<U></U> true......

i have a buddy with b16 with jdm itr pistons 2 layer head gasket and head is milled .005 (just to make sure it is true) which is 10.4:1 compression......

his HP was 182 hp at 8700 rpms!!!!!!!!!!!!!!!!!!!!!!!!!!!!!


tell me you need compression


and my b17 only had 1 point more compression!!!!! and HEADWORK!!

send me 100 bucks and i'll send you a 2 layer headgasket!!

 

Chad what pistons were in your B17A? PCT's?

 

is that ur website and number in your proflie..if it is i will give you a call tommrrow becuase i have tons of ?s..

 

standard bore PCT (ctr)


yes that is number where i can be reached and also the business which i drive the racecar for.....


car on track at vir....

 

how about keep your pistons, buy the spec C's and find a B18c Crank. THen you have 1.8 liters with a b16numbered block (even though it is really a B18C block, and then with the added stroke you can have your low 12 something compression to take better advantege of the spec c. Your Welcome.

we you can do it the way you have stated!!!

you must also get the b18c rods!!!


like i said higher is not always better!!!
only 15 more hp with headwork, header and 1.5 compression difference

 

What happens when the pistons stick out of your block 5.1 mm? what compression will you be at then? Id use a gsr or ls block if your gonna use a gsr crank and rods.Or you can get custom rods. You have a pretty serious deck height issue.

 

sorry forgot to mention the rods as well. slightly major oversight on my part. But why would the pistons stick 5.1mm out of the whole. The b16b block is the same exact thing as a b18c block.

Yes you are correct, B16B=B18c, same block. So with a ITR crank and rods he'll have a 12,5:1 CR 1,8 l Should be a nice match for a set of Toda C cams

I'm planning on the same setup, only I have a B18C6 and would need a set of CTR pistons to get there.

 

yeah thats what i will end up doing is the ITR crank and Rods...

 

Hey Chad don't B17A's w/ CTR's = Low 12:1's making you 2 full points over your friends B16A?

I was under the impression after seeing for myself they stick out of the hole -010" so they are more like 12ish:1 instead of say 11.3:1 with standard .020 PDH?

YES CTR pistons in a b17 block stick out of the hole .01!!!!!!!!!!!!!!


compression with ctr's in a b17 with STOCK HEAD and head gasket 12.474

 

btw, i do have a b18c crank if any interested
