Guys,

Is there a problem with oil getting into the AFM?

I have been told that it will ruin the AFM after prolonged use.

Is this true?

Yes after prolonged use it will go into the AFM but nothing a little contact cleaner and a steady hand can't fix. Dont want to kill the post but i have done signifigane dyno testing with air box's and found that a partition box with the air still accessible from the top is better than a completley enclose pod. The new Apexi filter is a non oil based filter and uses surrounding air from all area's. The Unifilter are a great product and i have used one in the past and the kit price is very well priced. But can i ask one question, why dont all you people who want a box make you own? It takes about 30 mins and cost ya about $20 :(

yeah no doubt some people are cable of making their own shield, this is a great option for people who can't or don't have the time.

The other thing I should mention is that I have seen a lot of cars coming from jp with an old HKS pod or similar. Generally, they either filter really poorly or are well and truely ready for replacement. Support a locally made and engineered product instead ;)

Couldn't agree more with you there Duncan, the ram pod should be one of the first things that people replace on there car when they first import it. Clean the AFM completly and then maybe look into using a non oil based filter from there. The Uni filter products are great and the contrstuction is top notch, if your in the market for a new filter guys take advantage of this buy as its a good price and a good product :headspin:

drinkan. can you help me out with a partition/box to suit my pod filter wearing 32GTR? do you still run the stock air box in your improved GTR? if not what are you using? :D

Yeah unfortunately we have to use the standard airbox for Combined Touring and Targa :P.

pm sent re details of the 32GTR kit, we can get hold of these as well

Hi Duncan, please send me a PM as well re details of the partition/box for a 32GTR. I have got the Apexi twin air pods setup.

thanks in advance

Just a quick note for those who already have a pod filter... I can get ABS blanks with a 90 deg bend in them... Got one for myself, because I have custom intercooler plumbing. I just need to shape it myself. If there is intrest, PM me. They are about $30 plus P & H. Probably less for group buyy.

Pics attached.

A free bump for the Unifilter Rampod induction kits.

I'm importing these into the UK from the good folk in Hornsby. Feedback has been excellent. I'm running one on my own GTSt, and also replacement Unifilter panel filters in my Delica, and Unifilter in my KTM bike.

The oil from these will NOT contaminate the AFM. Unlike some light oils that other filter manufacturers use, the Unifilters are oiled with a tackified foam filter oil. When you re-oil the foam, you squeeze out as much oil as humanly possible leaving only a sticky surface on the foam. Mine has been on my GTSt for ages now and there is absolutely no sign of AFM contamination.

I have found absolutely no noticeable diference in performance between runs with an Apexi dual funnel intake, a Unifilter Rampod induction kit and running with no filter at all (just the Rampod with the foam removed). Throttle response with the Unifilter Rampod and heatshield is noticeably better than when running the standard airbox. I am running 0.95 bar of boost and I suspect that the standard airbox MAY have been a little restrictive as this is well over the standard boost.

The Unifilters will also filter out far more crap than any dry foam filter, metal gauze filter or paper element filter is able to. A dry foam filter will only filter out particles that are larger than the spaces through which air flows in the foam. Metal gauze filter will only filter out particles larger than the holes in the gauze, and the same goes for paper element filter.

By the very nature of foam filters that are oiled with tackified oil, particles down to just a few microns across are filtered out as they cling to the sticky surface of the foam, rather than being drawn through. The majority of aftermarket filters will only filter down to 45 microns. Engine wear is caused by particle sizes as small as 17 microns, and something like a Unifilter will filter down to just a few microns.

Re the heatshield - it's not an enclosed box, but rather a partition that diverts the heat away from the intake, and is open towards the rear of the passenger side headlamp. It will not therefore restrict the intake of air into the pod as the pod remains open to air in all directions - so no worries there.

Final point - I've got to say that the metal construction of the Rampod intake tube is far better than the moulded plastic Jap Crap that nearly everyone for some reason is totally fixated on. It's about time people started to reliase that better stuff can be had from elsewhere other than Japan, and are far more sensible prices. Over here in the UK, the HKS and Blitz stuff is costing in the region of £200 just for the intake. The Unifilter kits, coming halfway around the world, are costing not much more than half of that including the heatshield and all taxes and freight.

Sorry for rambling..........just think you al should think about stuff other than what modified cars have on them when they leave Japan.

Hi Yogi, Unifilter only sell them as full kits, but thats good news since it gives you the chance to change your dirty, poorly filtering jp filter for a quality australian product :O

      S1 rb25/s14 starting problem

      By 25zenki · Posted

      Harness is for a s1 Rb25det, and it is engine and lower harness.  the old harness had broken off plugs and was in very rough condition/exposed wires and splices etc. it is not able to be put back on the car, I could visually inspect to see if they had rewired any pins on the ecu plug. The fuel pump definitly isn’t turning off it’s an external pump and very loud you can hear it. Will look at the other harness tonight, am also going to pull the fuel rail and watch the injectors spray, will update here with what I find. Pretty sure at this point it has to be something to do with injectors because car will fire up on starting fluid and cas is clicking the Injectors. Fuel pressure is steady 43psi

      S1 rb25/s14 starting problem

      By MBS206 · Posted

      Check the injectors flow evenly, and are actually flowing what you and the ECU think they should be flowing. If it's starting up on starter fluid, you have a fuel issue. Is it possible under cranking your fuel pump is turning off?   The harness you replaced, is that the whole engine harness? Do yourself a test, and drop the old harness on and plug it into the Z32 ECU. It's possible they've wired things different. From memory S1 to S2 is different in RB25 and you may have a wrong loom

      S1 rb25/s14 starting problem

      By 25zenki · Posted

      I haven’t pulled the injectors to watch them spray yet but they are clicking from the cas and all of the spark plugs are wet with fuel. I’ve thought the cylinders were being flooded from the beginning and was hoping fuel pressure would fix it. Tonight I am going to pull the rail and watch the injectors spray. Don’t know how to test/diagnose if the plugs are firing in correct sequence but that should be a timing thing and as far as timing goes my car still has the half moon for the cas can only install it 1 way. And my mechanical timing is 100% correct I posted photos above. Confirmed with the balancer on and off.

      S1 rb25/s14 starting problem

      I checked spark on all cylinders and they all visually have spark with the plug pulled and grounded, but plug 1 is the only one that fouled. This was a running swap that blew up and was rebuilt by a machine shop, put a new wiring specialties harness and did all gaskets, studs, and bolts while it was out.  compression is 135-150 across all cylinders. Aside from that from my understanding with the z32 ecu and maf the car should start regardless. The wiring for TPS and the dual 02 sensor/ dual knock sensor stuff shouldn’t actually stop the car from starting or even running well, (just slightly rich)  they just give fault codes. Car supposedly is supposed to start as long as you have z32 afm and ecu with the nistune base map and that’s info coming from a well known and trusted tuner who does a lot with SR/RB (Rsenthalpy). After more trouble shooting today where I’m at right now is that the cas is sending signal to the injectors they click while spinning the rotor, Fuel pressure is now set at 43psi, all cylinders have good compression and all of the plugs looked great (just wet with fuel) except for cylinder 1 which was very black (cylinder 1 has 150psi compression). all of the coils generate spark if pulled out and grounded out on the head. On the fuel pump car just pops into the exhaust. On starting fluid car will fire off. Hard to tell if all cylinders are firing off but definitley a couple. sounds like all of them but it’s only for 3-5 seconds hard to tell.
