Hi

I have a 95 series 1 R33 with FMIC HKS superflow pod and apexi neo piggyback SAFC/VAFC (not tuned yet) . I am having an electronic boost controller installed next week. with these mods and running standard boost it seems i am having some overfueling problems, seems to miss a little bit from 4500-5500rpm then takes off. That is what the apexi neo is for just have to have it tuned next week. There are a few questions I would like to ask:

1) Should I put in some splitfires, and do they make a noticable difference? Or do I just get NGK plugs and clean up my coils ( they seem fine)

2) should i get a decat, fuel pump , fuel reg, turbo elbow or downpipe ( dont know what these are for) . I cant get all this stuff at once but in which order should i get all these things.

3) Are there any reccommended dyno tuners in the brisbane area? Sorry I am new to all of this stuff.

4) the car seems to be lagging a bit since i put the FMIC in at standard boost, will this be improved when i install the electronic boost controller, I have been told that you can safely boost at 12 pounds with FMIC?

Any help would be greatly appreciated, thanks alot

Patrick

Hi

I have a 95 series 1 R33 with FMIC HKS superflow pod and apexi neo piggyback SAFC/VAFC (not tuned yet) . I am having an electronic boost controller installed next week. with these mods and running standard boost it seems i am having some overfueling problems, seems to miss a little bit from 4500-5500rpm then takes off. That is what the apexi neo is for just have to have it tuned next week. There are a few questions I would like to ask:

with your current mods, your max power will be around 180kw (no exhaust mentioned). splitfires wont be needed.

edit: just get some decent spark plugs, part no: BCPR6ES, then gap them down to .8mm or lower.

2) should i get a decat, fuel pump , fuel reg, turbo elbow or downpipe ( dont know what these are for) . I cant get all this stuff at once but in which order should i get all these things.

i'd definitely look into getting a turbo back exhaust to push your possible power to 200kw. you wont need a decat (illegal in most states and is a hefty fine if you get busted).

so, what you'd get before the tune:

-fuel pump (040, 044, walbro or nismo)

-exhaust:

get a split dump pipe, or a split dump/front pipe in 1. hiflow cat. and any 3" cat back exhaust you like.

-you wont need a fuel reg.

turbo elbow isnt an aftermarket item. its a standard feature on your standard turbo :D

downpipe = dump pipe (already mentioned).

3) Are there any reccommended dyno tuners in the brisbane area? Sorry I am new to all of this stuff.

hit the Queensland section of the site and do a search.

4) the car seems to be lagging a bit since i put the FMIC in at standard boost, will this be improved when i install the electronic boost controller, I have been told that you can safely boost at 12 pounds with FMIC?

i'd keep the boost standard till you get an exhaust. you'll usually gain around 3psi from a nice flowing exhaust. if you turn the boost up to 12psi now, then get an exhaust you'll run 15psi without noticing. so just install the boost controller, leave it at around 9-10psi and get the exhaust installed. if you hit above 12psi then you'd want to turn it back. i wouldnt run 12psi constantly on the standard turbo either.

    • Have a look at that (shitty) pic I posted. You can see AN -4 braided line coming to a -4 to 1/8 BSPT adapter, into a 1/8 BSPT T piece. The Haltech pressure sender is screwed into the long arm of the sender and factory sender (pre your pic) into the T side. You can also see the cable tie holding the whole contraption in place. Is it better than mounting the sender direct to your engine fitting......yes because it removes that vibration as the engine revs out 50 times every lap and that factory sender is pretty big. Is it necessary for you......well I've got no idea, I just don't like something important failing twice so over-engineer it to the moon!
    • Yup. You can get creative and make a sort of "bracket" with cable ties. Put 2 around the sender with a third passing underneath them strapped down against the sender. Then that third one is able to be passed through some hole at right angles to the orientation of the sender. Or some variation on the theme. Yes.... ummm, with caveats? I mean, the sender is BSP and you would likely have AN stuff on the hose, so yes, there would be the adapter you mention. But the block end will either be 1/8 NPT if that thread is still OK in there, or you can drill and tap it out to 1/4 BSP or NPT and use appropriate adapter there. As it stands, your mention of 1/8 BSPT male seems... wrong for the 1/8 NPT female it has to go into. The hose will be better, because even with the bush, the mass of the sender will be "hanging" off a hard threaded connection and will add some stress/strain to that. It might fail in the future. The hose eliminates almost all such risk - but adds in several more threaded connections to leak from! It really should be tapered, but it looks very long in that photo with no taper visible. If you have it in hand you should be able to see if it tapered or not. There technically is no possibility of a mechanical seal with a parallel male in a parallel female, so it is hard to believe that it is parallel male, but weirder things have happened. Maybe it's meant to seat on some surface when screwed in on the original installation? Anyway, at that thread size, parallel in parallel, with tape and goop, will seal just fine.
    • How do you propose I cable tie this: To something securely? Is it really just a case of finding a couple of holes and ziptying it there so it never goes flying or starts dangling around, more or less? Then run a 1/8 BSP Female to [hose adapter of choice?/AN?] and then the opposing fitting at the bush-into-oil-block end? being the hose-into-realistically likely a 1/8 BSPT male) Is this going to provide any real benefit over using a stainless/steel 1/4 to 1/8 BSPT reducing bush? I am making the assumption the OEM sender is BSPT not BSPP/BSP
    • I fashioned a ramp out of a couple of pieces of 140x35 lumber, to get the bumper up slightly, and then one of these is what I use
    • I wouldn't worry about dissimilar metal corrosion, should you just buy/make a steel replacement. There will be thread tape and sealant compound between the metals. The few little spots where they touch each other will be deep inside the joint, unable to get wet. And the alloy block is much much larger than a small steel fitting, so there is plenty of "sacrificial" capacity there. Any bush you put in there will be dissimilar anyway. Either steel or brass. Maybe stainless. All of them are different to the other parts in the chain. But what I said above still applies.
