Thread: Qr, Turbo, Nitrous - discuss

Ok first off, im getting a reman engine and turbo kit installed after christmas. I have a nitrous kit...
I am wondering...how hard can you hit a bone stock qr?
I mean, sure cams, tune, minor require fuel upgrades, but essentially a bone stock qr.
I don't have a death wish with it...lol I just wonder how much boost and nitrous a new one could take.anyone every hit one with both?discuss....
and if some one has..im sorry I missed it. I did see someone with a intercooler sprayer...also..discuss.....

Some guys running it, on a built engine.

Stock block, most say stick with 10 psi of boost, and im not 100% sure on the nitrous, but I think most of those guys try and keep it around 75 shot, maybe 100.

Running both would probably not be wise on a stock block.

With the stock compression, I think the formula for boost calls for a maxium of 8.5 psi or something along those lines (safely). If your reman is going to be aftermarket, I recommend lower compression pistons. If not. I'd just stick with 8psi and no nitrous. Better to sell that nitrous kit and get a meth kit to support the turbo, in my opinion. If your set on nitrous and boost, depends on what you plan on doing with your motor, how much your using it, and how much you want to spend on tuning. Personally with both, max id see is a 50 shot.
Meth would allow you to run more boost, and make that +50 horsepower or whatever because of more boost when spraying meth/water. + Itll be safer for your motor, and in general more reliable.
Local guy was making 350 wheel on meth/10psi on stock block (before he blew a rod)
You godda pay to play.

Great ideas and opinions so far.
So basically, 10psi and im pushing the limits of the bottom end? So basically the I should probably just guide a setup around 7-9 psi and try to make it as efficient as possible( size if intercooler/pipe, ect) and def run alk.
Has anyone gotten any numbers on a qr with intercooler sprayer? I don't wanna sell the kit I have .might as well put it to some use...
So. Stock qr with turbo and nitrous is a no- no.

Nate aka atomic guy on here used to run a 60-1 at 12psi on highway pulls, never had a problem from what i know. Also ran the 60-1 at 10psi daily... completely stock motor from what I remember. Ill ask him to make sure. I wouldnt be worried about running 10psi on my 50trim on a daily. I dont push the car often besides to merge onto highways but still not worried.... I wouldnt pass 100shot with upgraded plugs and a decent na built, i.e cams full exhaust header back... Maybe with the newer 3" header back combos there would be a higher threshold but that hasnt been tested yet.

11-12 psi on a stock block with a good tune is very realistic.

some OG guys know that 15-18 psi has been done on a completely stock block before. one of them being a local from the vboard/msv days that ran 18-20psi on a 60-1 for months with just an afc tune on 93.

edit* not months, but like 2 years

now that you mention it, there was a guy that ran 17psi with only a block guard and meth... tuned on a safc..

60-1... what are you guys refering to there?

Ok..well ...that's fuckin nice!
I guess I should be a lil more specific. Im planning on getting the base treadstone kit for now. Im guessing a jwt tune is how im gonna go on that end. Any advice? Engine is a Nissan reman. 0 miles. Bsr..moderate cam...93 all the time. Its gonna be driven everyday...and beat on somewhat. Looking for solid dependable setup. Not looking to break any records just wondering what's the limits.

treadstone kit with BB upgrade at 9-10 psi will be a fun daily. and still put down around 290-300whp depending on tune

It's not psi that will kill a motor, it's torque.

+1

I'd pick one or the other unless you plan to build the block...I guess you could run like 5psi and a 50 shot, but what's the point? Might as well just up the boost and sell the nitrous kit. Sell the nitrous kit and put the money into suspension mods...better to be able to put the power to the ground than just spinning the wheels.

I was under the assumsion that cyl pressure and det from running lean kill a engine.
Tq is just a measurement of an output ...right?

torque will kill your rods.

detonation/running lean will kill your pistons/ringlands.

in a nutshell, both result in death.

But isn't cyl pressure directly related to the amount of force applied to rods?

Run the turbo kit, and if you must use the nitrous kit, convert it into an IC spray. They say you can add 15-25 hp with that. I wouldn't trust running any shot on just a JWT reflash.

Thats my advise.
