should i go with b16 or itr pistons??? for 3500 i am getting a b16 head with b16 tranny and gsr block with new bearings, type r pistons with new rings and honing, so basically its a new block.

CTR if you don't want to then go with the ITR...

 

i would say CTR too

 

I 3rd that. Why not just buy a GSR motor?

gsr head will give you more compression that a b16 head.

 

get the ctr pistons w/ the b16 head, b/c im not sure on the clearances w/ the ctr pistons and the gsr head

Id say go CTR pistons with a double layer head gasket....but if thats a little wild for your liking, then go with some P30 pistons with a double layer head gasket. That'll be a little more conservative without getting all wimpy in the compression department.

 

do u guys know the actual compression ratio of using ctr pistons in a gsr block with a b16 head???..i will also be doing this setup shortly..

 

http://www.c-speedracing.com

under the how to section theres a compression calculator, check it out meng....

 

well i got 11.7:1 is this CR to high to run on pump gas without any tuning?!?!?

 

im not sure, but i think ctr pistons in a gsr block with b16 head is around 12.1:1 cr. my buddy has that exact setup in his civic si, and the thing just rips untuned. my other friend does a 14.60 in his civic, and the guy with the ctr's just pulled on him like crazy.

what guy with CTRs?? I mean i can vouch for TR cams pulling mad on the top end, but not enough details meng.....

 

its just a friend of mine...he has a gsr block with b16 head, type r cams with ctr pistons (standard bore) with an si tranny, rps clutch...it pulls a lot harder than my other friends setup in the same car-gsr block (stock internals), type r head and valvetrain, skunk2 intake manifold, gsr tranny, act clutch, 8lb flywheel. both have i/h/e's. enough info??

 

word, compression rocks

 

high compression and 91 octane sucks!

 

so get higher octane gas......then mix em.....you should be able to go up to around 12:1 on 91 with the timing at stock, maybe retarded a degree or two....

 

**** CTR pistons!

Its going to be a short lived Engine that will Be A nightmare!

Just go with ITR pistons, Your not building a race engine and the differnce Between CTRs and ITRs is very little!

Eric

 

If this difference was so little, than why the hell would it matter fool?

if you want an engine to live long all u got to do is not drive it like a complete tool.

Ok Fool, Im not going to argue with You being you speak like you Know Very little!

But think of this, By the time you retard timing for CTR's, You are not making alot more power the If you used JDM-USDM itr pistons

You Will make more with CTR's But In the end, Its not worth it IMO!

Eric

 

im running this setup currentley im just over my break-in period and really starting to beat on it. So far no problems at all besides a locked up dist. (damn 1'st gen b16 distributers )I have the skunk stage 2's The car is some what tuned w/ a vafc and eriks racing pr3 ecu but im still running very rich because im running large injectors (rc 320's ) because its going on the bottle. Go ahead let the flaming begin lol

dude.

im talkin about daily driving, retard the timing while on 91 gas, go to the track, dump in race gas, problem solved.

Power is what its all about IMO....but then again I dont know what Im talking about...

 

dont forget bout the final gear tranny!

 

i am going to go with jdm itr pistons...anyways where do you think my powerband will end...8200rpm??????
