Is anyone running a nitrous kit on their stock bottom end B20 VTEC ?
Is this not a wis thing to do? I get the feeling that it would need a resleeve before taking a 50shot?

Is anyone doing this reliably, or can anyone say to me that its a really bad idea (with reasoning behind both arguements)?

 

I wouldn't recommend it, tho we haven't had any of our higher compression (11.5-12.5:1) stock sleeved NA CRVTEC's develop any cracks I have seen others... Nitrous creates an enormous amount of extra pressure and that's a lot to put on their type of sleeve... I'm not saying that it wouldn't work, I just don't know how long it would last... Sleeving is really the way to go, drop some 10.0-12.0:1 slugs in there and sqeeze 150 on top of that, hehe... Just my $0.02... Latez

 

It could be done, but you have to tune it and set the car up for spray. With the extra pressure that Nitrous creates, you will have to bleed the cylinder by having a exhaust cam with a lot and duration. I have seen crazy amounts of spray on a stock motor (a STOCK 5.0 with a 400 shot single stage, 12 runs and it only blew a head gasket). It matters how much time and money you want to put in it.

 

I think in 18 months the block would be rebuilt with sleeves for a turbo, in the mean time I just want to keep up with my friends that have turbo'd B16's :D
You know the score

Thanks for teh advice, anyone else have a view on this?
