what exactly does that mean.
i saw this guy was selling a h22a. but said it was built loosely for nitrous so smtimes it smokes a lil in the upper rpms.

good buy? hes selling for bout 1000 and has 12:1 pistons eagle rods. aem fuel rail and some other stuff

what would i have to do to tighten the engine down(since it was built loosely)

 

^^this is the dumbest thing ever^^


if you dont know what it means dont buy the engine its not that hard to figure out

 

Lol


You can use nitrous on any engine. Some engines are built with stronger parts to increase power, and handle bigger shots with better ease.

 

Ummm...my guess; Built with looser tolerances?!

Personally, there is so much that can be wrong with an engine, that I would never buy something that I didn't have some major insight on. i.e. Engine was built by XXXXX shop and I have the receipts. Even at that I would be hesitant. It takes so little to screw up an engine build. This is a world where 0.001's of an inch can cause major disaster.

If you don't have insight, don't bother replying.

 

ok thanks for that
he said like the pistons rings or something.
but since im just going to get bashed

ill stop

 

actually its not stupid question at all. Only some of the replies are stupid. Yes when an engine is built "loosely" it generally means that the piston ring gaps and crank bearing tolerances are looser than normal. This is the stupidest thing ever for a street engine. Not sure what kind of engine the guy is selling you but i wouldnt buy it for my street car.

 

thanks alot i appreciate it and why wouldnt u use it on the street?
and could i just fix that?
and it is a h22a
its 12:1 compression eagle rods. and some other things aem fuel rail thats about it i think

 

You should really ask the guy what he means. Ive never heard of an engine being built loosely. I dont see any benefit in having loose rings even on a drag car, or I just don't understand the full functionality of having them.

 

he said it was cuz he was using nitrous on it. but only used nitrous on it a couple of times

 

im not sure how "loose" it was built but when going FI, the gaps are bigger then normal because of all the heat from turbo/nitrous. So the more heat, the more those rings expand. You should just ask him what the rings were gapped at.

 

ok would it be alright to drive on the street?or should i just find a diff h22a
and ill ask him when i get the chance
thank u

 

^ It really depends. Maybe he wanted to build the motor for 400 shot of nitrous which wouldn't be very good on the street because of the super big ring end gaps if you run it NA.

 

he was using a 100 shot
and ya i wanted to go na

 

In order for the tolerances to be put back to stock, the motor has to be torn down, and the rings, and perhaps bearing need to be replaced. So unless you can afford to have this done, no this is not a good idea.

 

NOTE:

what is done differently between a boost build and a NA build with piston to wall in mind?

Nitrous increases cylinder pressure just like boost, just faster. When you increase cylinder pressure, what happens with the heat? What does heat do to metal and what is done to compensate?

food for thought.

k thank you very much i appreciate all of your guys' insight
