Surely a new 255L walbro would flow more then a 18 year old GTR pump?

wtf? It's the 255l one...

So the walbro pump should be fine with standard 440cc injectors?

I was going to put a walbro intank fuel pump in my R33 GTR today but my friend told me that I need to get an aftermaket fuel pressure regulator first or else the car will run lean and use more fuel, is this true?

I use Motul 8100 X-Cess on my R33 GTR and I change it every 7000kms / 10 months. What about you guys?

My mate gave me a Apexi Power FC + commander for my R33 GTR and I'm contemplating whether I should put it in my car. The only mods I've done is a Apexi N1 Evolution catback exhaust, K&N hi flow panel filter and the boost is set at 1 bar. I don't really have that much money to modify it further and I'm pretty happy with it as it is. Would the PFC + tune be worthwhile in my near standard car and what kind of power gains would I be looking at? Should I at least upgrade my fuel pump and injectors? I've been looking at these injectors: RC Fuel Injectors Nissan Skyline RB24 RB26 660cc 660 cc: eBay Motors (item 280396155407 end time Sep-06-10 09:58:11 PDT)

I'll try put the originals in today. I think the popping from the exhaust is "misfire". If the original spark plugs work, I'm gonna regap the BCPR7ES to 1.1mm.

Yup, the old plugs are BCPR6EIX. They are so worn.

Hmm... I've searched these forums and lots of people recommend going 1 heat range colder and a gap of 0.8mm for a standard RB26DETT?

Just changed the spark plugs on my stock standard R33 GTR and now the car is running rich and there's a popping sound coming from the exhaust. The spark plugs I used are BCPR7ES and the gap is at 0.8mm. What do you guys reckon is the problem?

Has anyone cut wire #53 on the ecu of a R33 GTR to remove the speed limiter? Does it affect the hicas or anything? Don't want to spend $$$ on a HKS SLD or Apexi RSM just to remove the limiter... Already used the search button but cannot find any posts where people actually did this method.
