what spark plugs are good for a BUILT b16 running high boost and what gap? not sure how much boost i will be running until it gets tuned but probably around 20lbs...

boost means nothing without a setup rundown. 20 psi on a small turbo could only net you 300whp vs 20 psi on a huge turb would net you 600+whp. up to abotu 400whp heat range 7 is good, after that an 8 or 9 would be needed. higher number colder plug. BKR7E is where you want to start for 400-450whp

what compression is this built b16 even at? starting with a 7 and then inspecting to see which way you should go is one way to go about it

16 gap, stock ignition?

Im running a 32 gap @ 400whp pump gas 93 on brk7e plugs but im also running a summit capacitive discharge box and crane ps92 coil

Thats what I was thinking too and he's using the iridium ones which should allow for an even bigger gapping. I switched to brk7e after the recent build with a 25 gap but I have msd ignition, wires, coil so I'm wondering if I should use a bigger gap...

What MSD box? The regular boxes like 6a, 6al, sci dont like alot of gap from my experience, but if your running a CDI6 or 7 then you can widen the gap up a little if you dont get spark blow out

(Sorry OP not tryin to thread jack as I'm sure this will help you sometime too)

LS, its a SCI box...

then i would personall;y keep the plug gaps where your currently at. You can try going up, worst case is you get blow out and have to gap them back down

its 8.5-1 compression... and the turbo i am using for now is a precicion3431E turbo 57 but i was looking into the denso iridium plugs 2 steps colder??

BKR7E amen

bowtieboy911

I use NGK R5671A plugs. As long as your not using the Hondata S300 there all good....

bowtieboy911

i still dont know what im going to tune on i would like to use hondata but not sure which one

pcguy760

It all depends what features you want and how much you want to spend. You do not really need an S300 unless you plan on doing your own tuning, etc. (it has on-the-fly tuning which is nice to have but only in the right hands otherwise you can make your car go boom lol).

I think the Hondata S200 (WITH boost, datalogging and 2-Step) is a nice option for most people.

bowtieboy911

yeah i got it tuned with chrome pro before but i am probably gonna go with hondata i would like to get launch control maybe that no lift shift or they call it full throttle shift

pcguy760

Crome Pro has 2-Step if thats what you're looking for.
