Right now im running stock internals on my type r and I am running 100 shot direct port of nitrous...I'd like to build up the motor and run like insane amounts of NOS without blowing my **** up....of course I will dyno tune everything as well...

Turbo00

i would say get 10.5:1 forged pistons or maybe a bit higher and u should be fine with a 120 shot direct.

PM-Performance

isnt that what we already have?
what ever you do dont post this up on the r forum , i take a beat down whenever anyone sees my sig over there. . . . shti let me knwo when you do it . im curious to see how it goes, i wanna boost mine more soon too , but low on cash

Get some GOOD quality stainless valves in there or pay the consequenses!

Exhauast valves burn easy in hondas on NOS. 10.5 or 11:1 would be nice in the ITR.. stock pistons should be ok, just keep the NOS shot dead on, or even a little Rich...

hahaha I already paid the consequences lol I got skunk2 valves now I believe they should be good enough...so you think 120 should be ok? I do have cam gears and a VAFC I guess I would need a new fuel pump though huh? maybe injectors?

PM-Performance

deffinately new fuel pump. . . i dont remember if you got an ignition, but thats a good idea. i dont think youll need injectors though. dyno it 1st before wasting money. find out if shes leaning out for sure.

how bout Eagle rods or some other brand of rods...and what is a good fuel pump BBK Holley?????Walbro????? any suggestions

People_Mover

Keith, I like my Walbro 255, but since you are running such a high shot of Nitrous, you may want to go with the 317. The humming sound gets annoying, but after a while, you don't even notice it. I'll look around and find one for you. Easy install - my price free

Pinhead

255 should be more than fine I'll never go past 150 and right now im running rich....so 255 should be fine.....looks like we'll have some work to do when I come back and we'll all be SHITFACED just make sure it's after my car is done lol..... ttyl

i recommend stainless steel valves and je pistons with eagle or crower rods. you'll be able to push a 200 shot if you got enough fuel. Tony Fuchs had that back in the day.

Hey any of guys in Orlando change out valve stem seals? I need to get that done along with my valves getting adjusted. I am pretty sure the seals are shot. blowing little smoke out.

Pinhead

why Je pistons type r pistons aren't good enough...or should I drop down to like 9.8:1 or so???

People_Mover

Let's say this weekend, you all can come to my house and we'll **** our cars up (especially Keith's) and drink lots!!

FAST94GSR

**** our cars up? mines already fucked up, i wanna fix this ******!! haha no i just need to change out the friggin valve stem seals and then buy a new intake and redyno her. I want at least 200 to the wheels all motor, I know its in there..

I say forged pistons because stock cast pistons will break from the extra heat and pressure from the nos. I'm sure there's a pic of a piston exploded when a big shot of nos is used and its stock. its pretty ugly.

do it right the first time!

FAST-who had a buzz on last night and right now as I type!!

Pinhead

sure man I'm all for safety but what compression should I get 10:1?????9.8 what do you guys suggest...I already got skunk2 valves should I get springs and retainers too..and some head work I'm lookin for a 125 shot.....

FAST94GSR

I've heard from a NOS expert on the FI board that nitrous loves compression..

I would go with either 10-10.5:1 but definitely a FORGED piston..

Definitely get springs and retainers, that's a worthwhile investment to prevent valve float..

ARe you revving to 9 grand ? if not your stockers will work fine. depends on your budget? how much did your valves set you back?

I wonder how your car would run if we put my cams in your motor...hmm

FAST94GSR

REading my honda builders handbook for nitrous you want to open up the exhaust flow up to 110 percent. There's really nobody around here that I know of or trust to do headwork in orlando. You need to indicate to the porter what you are doing to your engine, what cams, how big a shot of nos, compression etc and he will (or should) port it accordingly. You don't want big hogged out ports that are designed for 10000rpm usage and sacrifice your low-midrange. Just a bit of advice..

Pinhead

I only rev to about 8600 or less...so what EXACTLY do I need....be specific please I'm a retard hahahaha

FAST94GSR

forged pistons and rods. everything else should be ok. I wanna ride in this car when its done. in fact i wanna ride in it now and compare how it feels to my car!

Pinhead

hahaha no problem bro...I'll take you for a spin when I come back to orlando january 7th so I'll save up for some pistons and rods and I'm gonna go ahead and get an apexi n1 exhaust and a test pipe I just wanna find somewhere to get all this stuff for cheap...I just ordered a Walbro 255lph I hear they are good so you guys gotta help me through this I'm GOING to go 125 shot if it kills me or my engine lol

FAST94GSR

it will probably be the latter! jooo gotta get some slicks man. I wanna see this thing run mid-low 12s

Pinhead

once the engine is done I WILL get some slicks I promise...they can't be that expensive...how long to them things last anyways????

xxplosif1

holy shitt! Keep us inform, i cant wait to see the results.

btw, should i be able to drop my times by about one full second with a 85-80 shot wet?

Pinhead

definitely with an 80 shot...I dropped mine by a little over a second with that setup....
