I am about to order a FULL LE2 package ( heads, cam, ported intake) and want to use my 125 shot of n20 ... BUT I still have the stock bottom end. I have EVERY supported mod everywhere else. Will I be fine, or is just the LE2 stuff on a stock bottom pushing my luck? Opinions are appreciated, THANKS ---

 

i would have to say ur pushing it. Ur bottom end will hold but for how long is teh question

 

I think you'll be fine. Dont go crazy with the spray and the bottom end should hold up.

 

Id say your pushing it aswell, sure it will hold up but how long, like camaro ss said.

 

I think thats really pushing it!! The LE2 on its own is about the limits of the stock bottom end

 

I'm a heads/cam car on a 125 shot too, if it blows up I'll let you know.

 

I would keep the idea of a motor rebuild on the back of your mind. As long as you are getting enough fuel, I can see it lasting awhile.

 

You're pushing it. The LE2 on a stock bottom end is what I consider the limit just because of the rpm's you'll be running and to add a 125 shot on top of that might blow your motor.

 

How many miles are on it? I'm going to be running a similar setup next year but have a rebuilt 355.

 

Yeah thats pushing it in my book. I would be worried about those stock pistons and rods. If you had ARP hardware in the rods, forged pistons, and main studs then you might be a little more safe.

Do a 50 shot.

 

It's pushing it, but I'd do it, as long as I have a budget for a built shortblock just in case.

 

I'm good.

 

The car is SUPPOSEDLY a 355 rebuilt 20K miles ago, but I cant seem to trust what the guy has said about other mods, so the odometer says 130,000, lol.

Maybe I should just go with a 75 shot, and rejet to the 125 after I get a full rebuild? Its the ZEX dry kit and it only comes on WOT, and uses an electronic fuel management box to control everything so it should be solid.

THANKS AGAIN ---

 

You will need a good sized injector to run a dry kit on that setup. Your injectors will be close to being maxed on motor alone.
