also i am not moding the nikki to be cheap just different, and maybe this thread can help someone ealse trying the same thing.

 

I ran 16psi non intercooled on a stock 135k mile 12a. No problems at all. Make sure you have it tuned decently before you start turning up the boost though. I turned mine up before I had the fuel pressure set right and ended up splitting 3 corner seals in half, and breaking 2 side seals. It still managed to have good compression so I didn't notice it until I took it apart to port it after running it at 12-16psi for 5k miles.

 

who is makeing turbo hats for the nikki?

 

o ya i was also wondering if any one makes a block off plate for the omp? time to premix.

 

I'm making them. 100 + shipping. Thread with pics and more info in my sig.

 

bad *** i saw the thread, and it looks sick!! it clears the hood no problem? what size is the inlet?

 

i cant wait to get mine, coldy rox!

 

Yeah, they clear the hood no problem. The inlet is whatever size you want it.

 

sweet 2 1/2 would do me good... i will look to pick one off u when i get that far!! but still where should i star with the jets? whats stock? i see that mazda trix sells them, just dont know the how big the diff between each jet is?

 

If it's a stockport 12a, then start with the stock jets. I was still running the stock jets in mine, but it seemed to be rich on the low/mid and a bit lean up high.

 

i was thinking 2#s up on the secs but what size is stock?

 

what no one like this thread?

 

Halo.
I could give you the specs on my jets.But i` dont think it will help ,since i`am running a BP.The venturies are machined,and so on.

The stock Nikki jets are .036 primary and .62 secondary.
With the mechanical conversion we find that the secondaries should be replaced with no bigger than an .060, while the primaries- depending on your driving needs- have anywhere from .053 to .058 installed.

I don't know yet about boosted application. It's something I could speculate on, but tossing a number is not tuning.
You have to be prepared to disassemble the carb top and play with different air jet and fuel jet combinations, and it takes a while.

That's the part too many of my customers don't seem to understand...We make our Nikkis completely tunable for this reason, but driving style, vehical wieght, transmission, porting, type of roads, altitude, temperature, filtration unit...and a few others, are all variables that can be compensated for by jet tuning.
There is no "one size fits all" approach...only a starting point.
And like I said, I do not yet have this information.

-Obviously the guys that do ain't sharing.

We'll be adding boost prepped Nikkis to our services list as soon as we know what to base-line jet them at.

 

Or they just fake it real well. Why open your mouth and remove all doubt.

 

i'll have the banana boost on the dyno soon. will play with some jets

 

As I understand it, you're getting the Boost Prepped Sterling Carb.

 

thank you for the specs... i know it takes time i was just looking for a starting point so i dont run it way too lean right at the start...thank you again.

 

You are correct as usual sir.

 

wait so whos doing boost prepped nikkis, and what is the expected output

 

yea, i'm the trial guy for the banana boost! wait i mean.... hahahaha, i'll have it on a dyno shortly after i get it. we'll see what can be done! WOOOO!

-zac

oh and here's what will be going with that amazing nikki....

-rebuilt/ported to all hell s4 turbo and manifold
-npr front mount intercooler
-msd fuel pump
-mallory 4309 rrfpr
-2.5 custom downpipe
-2.5 exhaust
-3 magnaflow 2.5" diameter mufflers (yes 3!) hahaha
-and debating on which clutch to use.
(racing beats or mazdaracing's)

 

I was hoping to beat you to the turbo 12a zac, looks like I won't be able to do it now, you are well ahead of me. Send me some pics.

so if the nikki works out good, how much would a boost prepped one go for, i like this idea, could save me some money, and get my blowthrough going sooner!!yay

so are you useing the stock intake mani.thanks

 

stock intake manifold that's been ported a lil bit. hahaha, not enough though. yet. WATSON, yea i am pretty much damn near done. just waiting on the carb and one other little piece. i'll take some shots today when i get a chance for ya. the intercooler sits in there real nice!
