ok so i have been searching and cant find someone posting what needs to be moded? sure people have done it, so how about what it took to get it done, like:jetting, turbo hat, floats..ect? come on share the know how.

 

680 whp how did you do it? come on some one.... anyone?

 

i would say the biggest thing to change in your carb would be the little flux capacitor needle they cant handle boost

 

haha flux capacitor maybe i should run beer injection.:d

 

gotta fill the float pieces, seal everything tight, use special gaskets that won't blow out. no choke, mechanical secondaries, umm.stuff?

 

y fill floats there rubber? i thought that only metal floats crush under boost? I just did a rebuild with rubber gaskets no paper crap, and converted to mechanical secondaries(big inprovement... but it is time to for a turbo!)

 

What are the stock floats in a nikki made out of? On my holley I had to use nitrophyl floats. Brass floats crush and plastic floats crack under boost.

You should be good up to 5psi on the stock carboretor.

 

but i dont want get by, i want to build it for up too 15psi on a sp 12a.

 

you need to contact robert from rotary shack, thats all i have to say

 

that may be right, but the stock nikki cant push more than 155hp so it would pretty much be pointless

 

Greg, I'm gonna have to call ya on this one, and ask just how you know that, and to please explain that to us all.

 

Well I must suggest that you need to do some serious research if you are concidering a stock Nikki for such an application.

I must also suggest that choosing the correct carb for such an application should be one of your lesser worries at this early stage.

 

i have looked in to this and found that it would probaly be easier and cheaper in the long run to spend $1500, and buy a 12a turbo from rotary shack...well put together factory turbo motor v.s. garage special...you do the math.....plus you get that cool red intake manifold.

 

If you are wanting to run 15psi then good luck with the stock 12a turbo, it is garbage and you will need an upgrade. I like garage specials!

bump for boost?? LOL i like that , very original!!

e-mail me and ill serve you up a boosted nikki, good for 500 hp if you god the *****

bump that for boost

 

Per the original question...... So what exactly needs to be modded on a Nikki to "serve up" boost?

 

alot!

 

of money?

Surely there are specific things that need to be done. What kinds of things are modded on it?


This board is all about sharing knowledge

 

That's only when it's n/a, and it's about 140, not 155. When you go turbo with it, the flow doesn't matter nearly as much and you can get a lot more power out of it.
