I know that this has been covered but i could not find anything that i was looking for. What i need to know is what machine work i have to do (becides boring) to get them to fit and would it be safe to run like a 100 shot with them or would i have problems?

 

The bore on the CTR and the GSR are the same; 81 mm. You do not need to bore your GSR's cylinders unless you get the oversized CTR pistons which are 81.25 mm.

As far as the 100 shot goes the pistons should be fine, but make sure the rest of your engine is up to it - ignition and fuel systems mainly.

 

you shouldnt have to do no cyl. work cause they are the same bore. so you can just swap them and enjoy( to the best of my knowledge)

 

with ctr pistons in a gsr you should be near 12:1 c/r. you do not...i repeat DO NOT want to squeeze anything in that car. not even orange juice.

LOL...I was thinking the same.

 

with the change is compressions..what gains would there be ?

POWA

 

Sure, you can just swap the pistons in, but while you're going through all the trouble why wouldn't you pull the block and punch it over? This will make sure that you get a good seat and seal. And that's only half the equation for running nitrous. you might want to take a good look at some nicer rods to go with your slugs.

 

I thought that the higher comp was better for n2o

Yes and no. You can run nitrous on high compression but the higher the compression, the more detonation you will get if you do not tune it right or you do not have a strong enough bottom end.

 

So with a 12:1 comp you can tune the car enough for everyday driving without risking cyclinder wall damage?

What shot? 100?

 

without boost or nos. friend told me that higher compression would cause detonation that would damage the cylinder walls and/or rods. (closest thread i can find for some answers to https://honda-tech.com/zerothread?id=899114 )

 

You talking NA. Yes, higher compression will make the motor run lean if you do not tune it (small bump in compression is not that big of a deal).

But with the higher compression you go, you should put cams and other mods (header, IM, etc) to get the best out of the compression.

When making power, Tuning is key.

 

like he^ said. you are gonna need to seriously upgrade your other components, mainly valvetrain. you might get away with stage 2 cams on that c/r. but even that will be undercamming a little. you will get the best gains if you get some stage 3 or spec c cams. but you will then definately have to upgrade your springs retainers, and valves.

 

whell i would like to run a 100 shot at the track and maybe sometimes on the street but not very often. i plan on upgrading the head and getting a port and polish job done on it. so what do you think the biggest cam is that i can go with when running 100 shot cause i heard that the bigger lift and duration of a cam is bad.

 

probably ctr cams. but...ctrs in a gsr is closer to 13:1 believe me or not.

 

yes you can run 100 shot on that setup but you are going to need something
to back off your timing when you spray! Crane cams makes a nitrous retard
that retards the timing the instant you spray wires right into your stock ignition.

I have been dealing with nitrous for about 11 years now so I know that setup
will run real good.

 

so you think that ctr cams are the biggest that i should run.

that crane cams nitrous retard is just a little com and how hard is it to wire in

 

the ctr cams are really good with that compression as for the timing retard device its really simple to wire in its a five wire hook up positive,negative, and the two wires that attach to the negative side of the ignition coil the in/out and a yellow wire
that goes to one of the nitrous solenoids so it knows when you spray so it instantly retards the timing to whatever you set it at.

 

do i have to use that or can i just move the dist.
