I see NISMO make a FPR but they don't say what the flow capability is. They don't even say why it's better than standard. But you'd hope it was! The good part is that it looks like it would bolt straight on. There's a bunch of eBay FPR's available too but most are generic types (of questionable qual...

Hey Josh, I wouldn't use the knocklite to tune until you have verified its operation with another method anyway. You really shouldn't need to tune much at all. 1) First check mixtures. 2) Once they are right take a couple degrees timing out on the last 4 columns. 3)Get boost level where you want it....

Yeah, true. There are plenty of FETs around that would do the job. The other way would be to just wire in a big power resistor to drop some voltage. It goes against the grain though! Probably the easiest solution would be to just use a brass tee in the delivery line so he could bypass some of the pr...

SR20 also has a form of fuel pump voltage control (they just switch a series load resistor in/out of circuit). I always believed that it was just to decrease fuel pump noise at low load. Once boost comes up the pump gets full voltage. Most (all) of the engine conversions I've seen run the pump at fu...

Hi Ed, Yeah, they certainly love timing. But in the midrange you gotta be really careful. 8.5:1. It's always tempting to add more timing but it will come back to bite you if you get carried away in the midrange. You can start tipping it in again up top no probs. They'll handle 20 degrees at 14psi up...

Ummm - yeah. Leave it alone. There's about 10 degrees extra in there already! Having said that, it's certainly worth checking. If your car comes on boost fast you may even need to remove some timing. Fortunately it's quite easy to hear knock in this area cos the engine isn't really making masses of ...
