very hard, it took us three days to figure out the 98 wiring diagram but after we figured it out it was easy to wire up.

the switches used to be for my NOS, but then i wanted some more power, so i went turbo....they're not doing anything right now, but they look fancy...the lights turn on when you activate the switch too...really fun to play with...i'm actually going to hook one switch up to a sylenoid so that i can regulate boost...it'll run 7lbs, and then 14 when the switch is on >:^D no clue what else to do with the others ***....i'm sure i'll think of something ***

the pods on the pillar are just 300zx pods (they don't quite line up, but oh well) and the cup on the steering wheel is just an autometer cup with a nordskog digital oil pressure gague. you can get em all from summit. i got it on ebay for 5 bucks *** >:^P

it's actually a stock shifter that has been slightly modified....the stock shifter has a plastic balljoint in it....we put it in a press and relocated the ball down about an inch or so...thus an instant shortshifter...it took about 2-3 inches out of the throw at the stock height, then i just chopped it off to make it shorter (i hated having that elephant dildo sticking up, i almost punched my LCD because of it)....so now i have a shortshifter with a REALLY short throw....when ppl drive my car i alwas get asked "is it in first or neutral?" it is VERY SHORT now.

i have yet to get it on a dyno....that should be by the end of the month, but it runs REALLY hard...i turned up the boost tonight...so it's running 10lbs now, and PLENTY of fuel to go around (i do have a bbk fuel pump, and 370cc injectors) i'm not sure about the HP, but it's enough to piss off a corvette >:^P i'll be sure to post more details after i get it on the dyno...i'm really curious myself

Quick Question

Kjopi,
Are you using the AFC along with the JWT ECU or are you using the AFC alone as your engine management?

i'm just using the afc for the fuel managemet...i wanted to see how well i could get the car to run without going JWT, and so far so good. it's a little tricky to get used to, but once you figure out the little tricks of the afc your set...it's really fast after that. i love it

kjopi, supposedly the SAFC has a corfrection program you can enable to fix the problem when using a blow off vlave that vents out tot he atmosphere. Have you experimented with that?
