this is my setup:

gsr block

darton sleeve's with a 85mm bore

wiesco low comp pistons

eagle rods

stock gsr head

drag 3 turbo kit

hks bov

tial 38mm waste gate

hondata s300

currently i traded some sub's for my buddy's nos kit and i threw it on just for show because i dont want to fvck up my investment but im thinking about squeezing on it and your views whould be greatly apreciated thanks!

 

ditch the nos and raise the boost instead!

 

the boost is already at 18psi the guy who tuned it said i shouldnt go higher without race gas

 

what turbo are you running?

 

ditch the turbo and run NOS, LOL. Seriously though...stock GSR head?, won't work with just NOS, definetly will not work with turbo and nitrous.
How much boost are you gonna run and how much spray?.
You will need stainless valves and a good set of springs locks and retainers to run the gas and lots of combustion chamber work no matter how small the shot, same goes for the turbo.
If you want it to be reliable, IMO do one or the other.

 

its a turbonetics 48 trim t3/t4 its kinda small

 

thanks thats the reply i was looking for

 

Great, "I" or "we" could go on for months about making a reliable set-up with proper tuning and the likes. however don't over look the basics, IE: good parts.
The GSR motor is possibly the best Honda motor that was made, throwing boost and juice on it is possible.
All the tuning in the world will not help without the proper foundation and all the best parts in the world will not help without proper tuning.
Racing springs will "snap" the valves shut quickly wich promotes better heat transfer through the seats, keeps your valvetrain from floating when you pulling for 10k and just makes a more reliable motor.
Combustion chamber work would be simply deburring and polishing after you un-shroud the valves you choose to install. The piston tops should also be deburred.
IMO, people have problems with nitrous and boost because these things are overlooked.
Good Luck with your set-up and don't hurt that GSR they are getting hard to come buy.

 

Don't listen to him. Saying nitrous won't work with a GSR head is retarded.

It will work just fine with that head and will produce power far and beyond what the jets are rated at because of the other ways it will benefit your setup. Just get it on a dyno with your tuner, run some colder plugs and you will be fine.

 

Just seeing Nitrous and Boost side by side makes me cringe..*Cringes*...See?

 

This is why I like Honda Tech so much.
Anyway, great reply(golf clap), very informative.
Why will a stock GSR head hold up to boost and nitrous?, please explain.

 

Why will it?
Because Nitrous is an oxidizer, basically it contains more parts oxygen than the air we breath (nitrous 36% vs 23%)

How is that different from a turbo? A turbo forces more air into the engine...

Is this a wet or dry setup?

 

 

Im not the one whining saying you can not use nitrous with a turbocharger, not my fault you fail to realize the basic concept.
regardless im done with you, if you have any comments or concerns feel free to pm me, ill be sure to answer them .

Op personally i wouldnt spray your setup, saying it cant be done is one thing, practically speaking I would look into a larger turbo and bigger injectors, sell the Nitrous kit for some $.

 

omfg.
go back and read the post....all of it.

 

WTF are you talking about why are you in this thread?

My friends has gsr was nitrous made 287/221tq then added a turbo kit and kept the nitrous on as well. The car now makes 455/305wtq off the bottle on a gt30r with a 50 shot for that extra top end. Car is totally stock gsr it's been through 20 bottles then turbo'ed and never had the valve cover lifted in the last 3 years and it's full of jobber parts water pump/tensioner/spring/t-belt was 65$ and it's holding way strong :p.

Outlasted my K by a shitload lol

 

--------------------------------------------------------------------------------

I love replies that start "my friends".
Yeah and my D16Z6 makes 900whp/1000ft lbs tq. and was built by GM.
Oh yeah no bottle or turbo and it runs on recycled bullshit.

 

Ran a 30 shot on my stock b16 turbo, to help with the turbo lag...turbo was a 60-1. Made 300hp and 219tq on 15psi, with the 30 shot (dry), made 389hp, and 297tq. Lasted a whole race season....lol.

 

its a wet set up

 

ya thats pretty much what everbody has been telling me and im already running 720 injectors. plus my turbo has been smoking like crazy and its on its way out so a bigger turbo is definitly on my lists to do

 

Gotta love how quickly people say Nitrous "wont work" with a stock head. Funny. Also love how "racing valve springs will help" ???? Honestly kids, shake your heads. The OP has a bottom end thats built like a brick sh*thouse, so go ahead and run a small shot for kicks, but make sure all is well with your motor and fuel system first, also drop your plugs a heat range, if you havent already. All the other usual stuff applies, like avoid detonation,get it tuned, etc etc. Dont jump into a 125 shot or something stupid like that, just use your head a bit.

 

I'd spray it! Just need to take some timing out when on the squeeze. Only thing I'd worry about is the backpressure from such a small turbo since the nitrous will create a huge amount of extra exhaust from the engine.

Supposedly a 50 shot with up to 25psi of boost is tollerable but I've heard of a 125shot with 30psi! Of course turbo size and other factors effect this.

 

I'm definetly shaking my head.
Another informative post from a nitrous pro.

 

No, I'm no nitrous pro. Ive only run my old LS crx on nitrous, then I turboed it, then I ran both at once on the LS. It wasnt built, just a stock, rebuilt bottom end, stock head, some arp studs...thats it! The garrett t3 (svo mustang) on the car was maxed out at 15psi, and it was a fun, reliable car. The nitrous was there for sh*ts and giggles. Didnt hook up worth a damn, either. Ran that car on nitrous for the first year, at last one good shot every day on my way to work. turboed it the next year, then figured that I have the bottle anyhow, so why not run both?? Do I have any dyno sheets to prove anything?? (I know that will be the next question) No. There is no dyno close to where I live. Did it work? Yes, and the person who has the car now is still beating on it, minus the spray (I kept my setup when I sold it).

Your statement of "the stock GSR head wont handle nitrous" is a wide, blanket statement that, simply put, it a foolish one. Almost any (healthy) motor can handle a small shot. Your logic on valvesprings "snapping the valves shut" to aid in cooling the valves is also mildly askew. By your logic, anyone who runs a high duration cam with nitrous is doomed, because the valves will be off their seats for an even longer period of time! Really, the springs are there to prevent valve float issues, and coil binding issues on a high lift cam. You did state that. I wont touch on valve harmonic issues here, it isnt necessary.

As a side note, you should really check out how many guys are running JRSC setups with spray!! In fact, a small shot of nitrous is a BIG help to those guys for cooling their intake charge! I built an 11psi JRSC'd D16Z6 last year for a good friends daily driver, and putting a 35 shot on there is looking like a good option for him too.

Am I a nitrous pro? no. But I have built many, many motors in the last 20 years, from circle track , to whitewater jet boat marathon motors, to VW, to Hondas.

 

Read it, 15psi, 35 shot both a massive waste of time money and effort.
And not a good foundation for any argument.
Whats the point?.
