hey guys. im new to the ka-t thing but im building a very mild ka-t for now. if anyone could tell me some good numbers to tune it according to what i have.

Fresh bottom end (new rings and bearings)
bottom mount turbo manifold
t25 turbo
370cc sr injectors
Greddy FMIC
HKS SSQV bov
HKS Hi-Power exhaust
Apexi SAFC2

Can anyone tell me some safe numbers to tune the SAFC to? Also I was told to turn the base timing back 5 degrees to 15 degrees btdc? What heat range plugs should i use?


Im looking to upgrade to bigger turbo and stuff later i just want a basic tune idea so get this thing to start for its first time. Thanks guys i appreciate it.

 

set timing back like 4 degrees, better yet just get an msd btm and knock light. as for fuel management a good base to start with is the 370cc/maxima or rb20 N60 mafs. a bit rich but you can drive with it. get a wideband on there and see if you can pull some fuel in the lower and mid range. ngk bkr7es-11

 

thanks

 

what do you suggest for the gap on those spark plugs?

 

.026 to .028

and you may have to add a lil and take away all turbo setups are differnt in someway do to all the variables

 

i use very wide .038 gap

 

meehhh.. like i told the young chap it varies for many setups.. my turbo would blow that out lol

but as long as its under .044 ( stock gap) your somewhat ok.. close to .044 is pretty hot

 

thanks guys

 

actually yea go with about .033-.038 seems to work better for my in cold weather now... gotdamn climate change.
