Need Help Tuning Toda Spec B's
Hi,
I'm looking for advice from Toda Spec B owners out there. I don't know where to adjust my cam gears and distributor timing. I have: Toda Spec B cams, Toda cam gears, Toda valve springs, Portflow Ti retainers, Spoon drop in filter, Spoon 70mm throttle body, Mugen 4-1 header and exhaust, punched out cat and a SX fuel pressure regulator. Oh, also all this is in a JDM B18C. As of right now the cam gears are at stock, fuel pressure is at 41psi at idle, and distributor timing is advanced 2 degrees. I'm also planning to get an upgraded computer in the future. What are your recommendation for this setup. Any advice with the cam gears and distributor timing will be greatly appreciated.

There is this great new machine called a dynojet. Put your car on one of these and tune, tune, tune...then you will reach the settings your looking for young Jedi. Don't use others settings unless you want me to give you a big
The dyno is your friend...remember that

.....I got the best results from my setup by advancing the intake cam and retarding the exhaust cam. try +5, -5 and go from there... also try raising fuel press to maybe 50psi with the vacuum line off...
if you have a vafc, raise the crossover to a little over 6k - maybe closer to 6500, and trim/ add fuel in different parts of the rpm band for minor corrections.
You will have to do this on a dyno, with a wideband o2. Shoot for a 13.5:1 a/f ratio... I'd expect 190whp sae corrected. Good luck!
