How much NOS spray can this block take?

[98GS400Turbo]

3" Exaust
Stock block (bored, balanced...)
JE 2618 custom pistons 8.2:1
pauter rods
.10 over

I'm giving up on the turbo for a while, so I figure I'll just spray it, fast, cheap, dangerous.

The above combo is not cheap.

Bored and Balanced (assembly and engine installation) will run about 3k
JE Pistons run about 1000
Pauter Rods run about 1400
NOS system & Installation 1000
Fuel pump: 130
Injectors 600
Tuning 1000
Misc.. 250

I've already paid, engine has been running well for a year. With NO BALLS! NO BOOST! NO SPRAY! Because the original tuner screwed me real nice and never did any of the hard stuff (build the piping for the turbo....)

So now I'm tired of waiting and just want to spray it instead of paying another 20k or so to have it piped and get turbos, and all the other nightmares we've all read about.

What were rods made of? Stock motor can take 125 shot safely, and 150 pushing it. if you have all forged internals i wouldn't say a 200 shot would be unreasonable at all. Of course for a 200 shot youd have to do fuel mods, most probebly a progressive n2o controller, at least 2 step colder spark plugs, etc. And its not dangerous if you do it the right way, its just n2o has a bad rep. from people not obaying simple rules... like never hit the rev limiter while spraying... only spray above 2500 -3000 rpms... and other stuff. But i agree, nitrous would be a cheap and effective way to see some good things come out of all the hard work youve done to your motor.

I really don't know what the pauter rods are made of. Probably good stuff I wonder what the worst it could be is.

 

[Lextreme II]

I have seen them. They are either I or A beam. They are the same rod for the Tundra. http://atomicspeedware.com/newrodspaut.htm

How much of a shot do you think the stock transmission with a shift kit installed will handle?

 

[Lextreme II]

Shift kit has nothing to do with how much your engine can take. I would say about 100 to 125 since u have rods and pistons. Most importantly is tuning of fuel and ignition. U can get bigger shot if you have proper tuning and fuel supply.

 

[xirforever]

yeah, only thing stopping you from going really big is ignition and fuel supply, just get the bigger fuel pump from lextreme and upgrade your ignition along with a step or two colder plugs. And if you go with a dry kit you might want to upgrade your injectors.

compression doesnt effect spray. You can have 7:5.1 compression or 11.7.1 compression, its only as good as the pistons are.

I put over 200 RWHP on the stock motor and didn't have any problems.
Pauters X-bean rods are in my oppinion the best in the market.

With Pauter rods, and J&E pistons, I see no reason the motor couldn't handle over 1000HP If the fuel is right.

Bob,

We finally got the Pauter Rods in performance parts collection.

 

[98GS400Turbo]

Engine is blown now. block is cracke,d hole in piston, apparently a valve stuck open, knocked a hole in piston, and somehow cracked the block? And this is with no nitrous yet. What happened?

 

[Red Supra]

got any pics of the blown motor?

 

[lowboost]

did you have any FI?

 

[sniper]

Any pix? Because you had low compresson pistons, the valve should not have even hit the piston, let alone blow a hole in it...............Load some pix up so we can see what happened.

 

[Lextreme II]

What happened? Please take pics....... This doesnt sound right. You have good internals and blow up???

 

[lowboost]

well one thing is if you did have low compression pistons it would run like crap with or without spray, it prolly wouldnt have 150whp! Something wasnt done right, first off is that you cant have to low compression without a turbo or something! also I bet the reason it blew was lack of oil pressure or oil level, and reving to high

 

[rarson]

If a valve stuck open, chances are it's related to the timing belt, or perhaps a valve spring (or retainer/clips).

 

[98GS400Turbo]

You think we can fix it with a little jb weld?

The new ls400 block is at the machinist now. If we drop another valve, I am going to go postal.
