would a b18b be able to handle 15psi+ small shot of nitrous with a new crank, pistons n rings, cams, and if i got the block resleeved?

 

you would need pistons, rods, and maybe a block guard. no need for new sleeves or a crank. stock sleeves can handle about 500 and some change safely. and i have never seen a factory honda crank break. i have seen nitro funny cars crack a crank, but thats a totally different world, dotn worry about a crank.

your biggest concern will be a proper tune when doing 15psi and nitrous. i hope too run 18 and nitrous with pistons, rods block guard and a good tune

 

so if i go with an ext wastegate do i still need a boost controller?

 

If you want to change your boost levels then yes,

you can buy different sized springs and just use the Wastegate. That's what im doing with my tial

 

so should i get a wastegate an spring for the maximum amount of boost ill be running.. because i know theres boost controllers with a hi an lo setting.. so could i have my hi setting say on 20 an low on 8 but use a wastegate+spring for 20 psi?

 

your boost controller is going to regulate the amount of pressure your spring sees, so it shouldnt matter...i think, not positive, so it doesnt matter what spring u have. just make sure that whrn u run lines for the boost controller that nothing gets pinched, becasue if it does, then you might not have a motor anymore

 

Judging by your numerous threads (which I can point out if you'd like) you have no room to talk about being "owned".

On top of that he has stated that his power goal is between 200-300hp, which is a big ranged goal. But still would only require low boost, which an internal wastegate would be better suited.

 

You don't need a boost controller or a thicker spring, just put a needle valve in-line with it so you can crank down and limit the amount of boost your WG sees, it's a poor man's boost controller, and there's almost no limit to how much boost you can make. A close friend of mine is a Saab fanatic and he's currently running a primer-blue 1986 Saab 900 chassis with a boosted 2.3L engine to 47PSI of boost this way. He had to lower the compression ratio so low first to take all that boost.

 

i wish i had a tial wastegate i have some pos that came with my drag kit...

 

i tend to agree with you about that guy....


But it depends on the turbo size. If he gets something smaller and wants to hit towards the 300whp side of the coin, He would have to make a decent amount of boost. For that the tial wastegate would be better.
