blow through nikki

[mattallac]

well have a side project fb drift car a friend and i are building with all of our spare parts and cars ,has anyone done a blow through nikki ? all im gonna run is 8psi max on my n/a 12a . the car will be drift only trailered to the track ,if the motor pops in goes another junk yard motor. any help would be greatly appreciated.

8 psi is pretty low in my opinion , webber for 500 is a little steep for our budget and i can drill the jets for more fuel if needed .rotary shack makes a turbo hat for the nikki so i would think it has been done before

I guess we have a communication problem , a BOX and a HAT are two different things ,and the least of my worries. I am looking for someone who has moded the nikki carb before for a turbo application. ( power valve , e tubes ,plugs ,etc) I really don"t need opinions ( not to be rude ) ,just some tech from someone who has done this before. thanks

boost prepping a nikki is easy. pull off the smog crap, make the secondaries mechanical, drill the acc pump squirter, jb weld up any open holes. done.. you will still need to jet the carb. what size is the turbo?

[mattallac]

the turbo is a t3/t4 we are only gonna run 5 to 7 psi on an na motor . you know about what to do for the distributor ? Q- drill out the acc pump :how ?

the distributor needs to be locked so the timing does not advance 30 degrees when your making boost. the timing should be set at 15 degrees advance total, more boost, less timing..
to drill out the accel squirter remove it and use a jet drill set to enlarge the holes. i will measure the one i use an get back to you ...

cool thanks

well the distributer is done now i have the carb open looks like 3 jets per bank , so drill the jets that are in line with the squirter correct? leave the other jets alone ?
