I was just wondering if this set up would be a match for a gsr?
B18b head-
with a wild port and polish job, crower stage 3 cams, crower springs and retainers, new valves, and a larger fuel pump with a 2 or 1 layer head gasket with 2 layer ill be pushing out about 11:7 compression and with the 1 layer ill be pushing 12. what does everybody think i should do to get max power (92 octane) should i mill my head at all since compression is already going to be high?
B18b block-
jdm ctr pistons .025 oversized, machined to my ls rods and balanced, and a machined crank

P.S. I will also be running a hondata stage 4 programed ecu

if so what other parts can anyone think of for me to use on my build up to beat a mild built gsr thanks!!

IMO it's not even worth it. After spending all that money you could do a LSvtec setup.

 

b18b's are not bad...
it should make good power, nice torque
Compression with ctr's is about 12.4 with the stock 3 layer head gasket.

 

I've been toying with the idea of tuning a B18 with a much higher rev limit, and maybe a type r tranny. That should take any stock GSR by far.

 

c-speedracing.com there compression calculator says my compression ratio with ctr's with stock oem 3 layer head gasket would be 11:4

 

I thought I read in SCC that the CTR pistons hit in a LS. Do you need to cut the relieves more to use them?

 

CTR's are great in an LS.........I have them......11.4:1 CR, awesome power.

Don't listen too Non-Vtec haters! Look at my sig. The head has not even been pnp and I am in the 13's. I spent about 1500 bucks on the build.

 

hey wat up i need to know how well my set up would do can you help me out and tell me if it is good or should i go with some other parts?

SET UP:
B18b head-
with a wild port and polish job, crower stage 3 cams, crower springs and retainers, new valves, and a larger fuel pump with a 2 or 1 layer head gasket with 2 layer ill be pushing out about 11:7 compression and with the 1 layer ill be pushing 12. what does everybody think i should do to get max power (92 octane) should i mill my head at all since compression is already going to be high?

B18b block-
jdm ctr pistons .025 oversized, machined to my ls rods and balanced, and a machined crank

P.S. I will also be running a hondata stage 4 programed ecu

c-speed racing is wrong, search and youll be surprised.....
pct's have different compression height than pr4's
pr4, p73 and pct's all have different compression heights, pct being the highest one..
Dont forget that.So in c-speed calc you got to change piston to deck height to 0

But whatever floats your boat....

 

would it be safe to run ctr pistons on my ls with 92 octane gas? will i have detonation?

 

not trying to cahnge subject but wondering if you know what i would have to do to put my 91 LS motor in my 94 civic ex??? please help out if you can

 

the motor should bolt right up and all you need to do is get a ls wiring harness and ecu

 

with hondata and good tunning you should be ok.
people run pct's in ls/v's with no problems.

Power is good. Consider better gearing.
Get either a Si(R), GSR, ITR tranny. You're see wonders.

 

If you are not rolling in cash, stay with the LS tranny and build the motor the way you want it now. You can put a tranny in later without pulling the whole engine out again. I am running LS tranny!!!!

 

I would advise against the ls tranny those gears are way to long for an underpowered ls. i'd get a b16 tranny those can be had for pretty cheap.

Don't take this the wrong way, but BS!!!! Its not that bad, and I know cuz I got one. Sure maybe a ITR's 4.785 FD would be noticable. But B16, come on. Your talking 4.2 LS vs. 4.4 Si. Not worth it. Just my 2 cents.

 

B18A all motor would be chill. GSR motors built right are really insane. I had an LS/VTEC CRX running mid 13's but I totaled it. I now have a 96 Civic DX with BUILT GSR motor and a mild 1.9L bore. Puts 205hp to the wheels. It would be hard to beat a car with a GSR if the GSR motor was built right. Build it up and let me know man. Later

 

I also had a ls transmission and it lost 2nd gear so I switched to a b16 tranny I had laying around just to get me around and I noticed that the 3,4,5 gears were dramatically shorter and improved acceleration noticeably.

this was all on a stock ls

 

bump!

 

doesnt take alot for an LS motor to take out a MILD gs-r like you stated, but driver plays the biggest key.

MMMMM, no ls tranny's are not bad, but there is a world of a difference if you switch to a b16 one....
Short gears do wonders for a ls motor
also not only the final, but also 2,3,4 and 5 are shorter.......worth it?sure
