I am rebuilding a 94 Camaro, fairly mild build, stock cube rebuilt engine (all stock short block) mods are small cam (Crane 227), 1.7 RR, LE1 heads and air, egr, smog delete all on a mid sized stall and stock 3.23 gears on Nitto Nt05 drags. Goal was 310-325whp before a power adder.

So here is the question......

Rear mount Turbo or Nitrous? I had planned to go turbo and purchased all the parts from a take off from a fellow forum member, even left the stock manifolds on because that was the advise given. I recently found (from another forum member) a brand new NX nitrous MAF kit so I purchased that too. From my reading, the turbo boost will need to be limited due the the higher compression of the LT1 and to get to 150 whp I will be pushing the limit at about 7-8 lbs. On the other hand the nitrous can be pilled to 150 and from reading, the higher compression is not a bad thing for the nitrous. So with both on the garage shelf, which way would you go with?

Advise??

 

You are gonna have to provide more info on your "stock cube rebuilt" engine. Such as which crank, rods, pistons, rings, rod bolts were used etc. I believe a 150 shot of Nitrous is a large shot for a stock short block.

 

All stock.....pistons, crank, rods, rings, bearings, everything to stock spec. It was a 90K mile engine when rebuilt has 0 miles on it now. The nitrous kit is a wet MAF kit by NX. (modified my original post with more info)

 

Your ring gaps are all wrong for either of those and your pistons are weak. You should just change pistons while you can and do whatever else you need to make it last. It's one thing if you weren't in the middle of a rebuild, but since you are, you're not going to want to do it again any time soon.

 

Engine is already back in the car (took 30hrs), I do have the block that was in the car when I purchased it back. I can have that engine redone with better pistions, rings and bearings waiting on the stand when and if this one eats itself. So I take it 100 shot is max on a stock block?

 

I'm not sure if you can go 150 safely since those are only estimates of what the nozzles do- just make sure you have a good fuel system and safeties in case fuel pressure is inadequate. You also need to take out your timing and may want to be conservative with that since nitrous can take out your engine in one run if you don't get it right. If you do get it right, you will go 10's for a while.

 

By adding headers and a good exhaust system you should exceed your goals minus the nitrous. That cam only has produced as much as 360 rwhp.

 

I purchased a nitrous filter, bottle heater, presure gauge and a fuel presure saftey switch. The kit comes with a window switch and WOT switch. I am set up for a dyno tune with a well known engine tuner/builder down in RI so I need to choose the direction so I can have it ready for the Jan 3rd appointment. The Z will be a street car driven less than 2500 mile per year. I have other go fast cars but this one has some history behind it. I would like it to be equal or better than a LS3 Vette which I believe is a 12.2-12.4 car. Lots of advise on the nitrous, is the turbo out of the question? Thanx for the advise so far, I am very new to the nitrous thing.

 

Might as well do both. Use the nitrous to cool the turbo discharge and you might only go 1/4 mile instead of 2500, but it will be fast as hell.

 

Too funny!

BTW looks like we have similar taste in cars and bikes.
