I got a 2001 Prelude SH with AEM CAI, ZEX colder plugs, and 55 shot DRY, I also got axel back duals mufflers so I have little back pressure, or less at least. My motor feels like its struggling in vtec when I push it nor does it feel to pull as hard, when Im not on the nitrous and I dont really notice it when I am on the nitrous but it doesnt seem to pull as hard either. I dont know whats wrong, I havent been spraying for more than a month, but I have sprayed like 3 times in a row on occasions like twice. Thanks Do you think its due to the nitrous? I DO

 

Do a leakdown test. Check your coolant for oil.

 

can you explain what a leakdown test is, and what does check your coolant for oil mean

 

it means that it sounds like you blew a head gasket or worse. Do a compression check

Do a compression test first. It'll clue you in if it's an internal problem, or some other problem.

It could be a number of things. Preludes have weak ringlands, so you might have blown that. Do you get any black/gray/white smoke out of the exhaust?

Or it could be as simple as a worn out clutch. (Let's hope it's just the clutch and not a costly engine rebuild)
