Im building a GSR block to take some NOS. I going to have 8.5:1CR pistons or 9.1:1CR pistons. Im going to put a direct port it on the block. With the stock bore or over .5. I want to know how much NOS I can put on the block before it blows?

I have a cable B16 tranny. Should I get a cable LS for longer gears?

Also what head gasket shopuld I use to make the CR go down?

 

i wouldnt lower the compression ratio THAT low.. You will see a loss of power when your not on the bottle and that sucks *****.

 

N20 and compression get along quite nicely, dont go that low. If you have the components that can handle the heat load then you can probably run a 100 to 120 shot. Make sure you have a clutchand good ignition system that can handle it also.

 

Go with 10:1 C/R.

 

So I should just get some Forged Je 10:1 CR pistons...

What should I do about the tranny.. I have a a JDM Y1 right now.. should I keep that or get a LS

 

just make sure you have enough fuel. i used 9:1 je's with a stock block b16a2, the head was built and a quaife in the b16a2 tranny. i melted a pistion with a 120 shot because it got a little too lean. i like the b16 tranny, i think youll be fine with that one

 

I will stick with the B16 tranny,

what did you run with the 120 shot?

Let me know

I was wondering if JDM ITR pistons would asking for trouble with a 125 shot??

 

it was a 99 si that weighed about 2450 and i ran a 13.1 with some traction problems in 1st and 2nd

 

Well I have a built head, GSR head, with skunk 2 manifold, type r TB, RC 330cc injectors, STR fail rail, JUN valvetrain and also JUN 3 cams.

I want to get it down into the low 12's with the Nitrious. Can it be done?

I still dont know if I should use some JE 10.1 pistons or some JDM ITR pistons.

 

im sure you can get it into the 12's no problem, you have a smaller car, what size shot you gonna have?

 

Spencer's stock B16A (well besides a ITR IN cam) did an 12.6@108 a couple years ago in his EH2... That's nothing too special but okay for his motor with an 80hp dry setup... The LSVTEC blew up last season after running 12.3@112, we resleeved it to 84.50mm with 10.5:1 JE slugs and he's looking at 200-300hp progressive (just needs to find solenoids which will handle it)... Bottom line is I don't think you'll have problems hitting 12's... Read your plugs and don't get greedy, any signs of detonation, etc. pull timing and add fuel... Better to be safe than sorry... Also I absolutely would NOT swap trannies, your B16 will be fine... Same way with boost, I hate long gearing... You have to bring into consideration your power, overall tire diameter, etc... We run B16's and GSR's on 500whp+ FI cars so I'm sure you'll be fine... Just my $0.02

EDITED: I had a few errors

I was thinking a 125...

 

im sure you could run a 12.5. i gotta big hog with a 120 shot and ran a 13.1 so good luck man

 

The JDM pistons will melt on a 125 shot. GO forged and coated if you can. That will give you longer life. ANd I agree with the gusy on the B16 trans. It will be a hauler.

 

you can post topics on h-t but you cant respond to my im's? wtf man

 

Adam....correction...The "all motor" b16 only had a type r intake cam and went 12.6 @108 wit a 80 shot .......The ls/boom went 12.3@112 with a 70 shot before i realized it was a bad idea to squeeze on stock sleeves with a 1mm overbore. I have the progressive system figured out. When the track dries out we shall see.

 

Hey buddy what's up!!! Good, when it does you gotta take me on a ride so we can make a new vid... We don't have any good nitrous stuff yet...
