Nismo FPR on Lowports

629 Views 5 Replies 4 Participants Last post by  97SE-R C2
Will the Nismo FPR work on low ports? Just asking because the injector rail is inside the intake manifold as opposed to on top as in high port motors. I'm just thinking it would be a real bitch to adjust the regulator. If any lowport guys are using it please share your experiences.

Its not that hard to adjust at all. I took off the intake manifold bracket to adjust it easier. Make sure to put it back on though.

nismo sells a fpr that is also universal.

Ok so its not that hard to adjust. Now some more questions? Adjustment is that done at idle? Also in order to know what your doing your going to need a gauge. Does The nismo allow a Gauge to be plugged in? If so what would be a good gauge to get and where to buy it.

its needs to be adjusted at idle with the vac line disconnected. as for a gauge you can get a small fpr gauge from summit racing with the hose adapter for around $20.00
You'll splice the adapter in the fuel line and run that to a gauge (usually a short piece of fuel line to mount the gauge to the firewall).

This is from Andreas on adjusting the pressure for a 4 Bar 370cc setup.
Set the Fuel Presure to 59 psi with the vacum line off. This will be what you are looking for. If you want to run xtra high HP set the fuel prsure to 60 PSI with vacum line on but only do so if you are trying to get more than 270 WHP do not go for more than 290 WHP with second setup.
