Fuel Problems


Recommended Posts

Hey guys,

I have a r33 RB20E

I'm getting 250kms per tank on ultimate, and 300kms per tank on optimax, just had new plugs, new oil, etc. I only rev out gears occasionally, and i cant seem to work out why my fuel economy is so damn bad!

Ive put up with it long enough, but now its past a joke!

I only live 5-10kms from school so it does do a fair few cold starts a week...

Can someone suggest how i can go about fixing this? and getting a bit more kms out of my tank, i dont have any complaints about the car bar that. I was thinking dyno tune, but what else is there?? and is this even possible with the stock ECU. Also, is there anything i can buy aftermarket to make the situation better? can i advance timing etc??

Thanks guys....

hmm... 250-300 to the tank is quite poor.. specially in a 2L car...

I wud recommend maybe try resetting the ECU? (there are threads - try a search)

clean the afm? but yeah a dyno sounds like a good idea and will save u from mucking

around - check the AFRs and see how it goes.

keep us updated man.

a rb20E or a ca18 skyline wouldn't be too fast...

and mate some people say to spray the sensor with contactor cleaner - whereas I recomend circuit board cleaner as contactor solution does leave a residue

rb20e is a little faster then your 100kw corolla, civic si,vti, etc!

not the fastest thing, but when youve just turned 17 i dont think you'd really care.

i'll try that, and a few other things today n let u all kno how i go.

yeh there are a few owners on sau....

there's even been a CA18 33

CA18 was R32 (GXi model) only, thankfully! I think a whale would be a bit too much for the poor little 1.8L to cope with....

R33 GTS (ie no '25') has the SOHC RB20E for reasons best known to Nissan.

Yeah, now i just need a few more things and it'll be sweet:)

Yeah its a series 1.5 R33 skyline with an Rb20E

Pretty strange i thought too, but it'll do for the time being, might even turbo it, but i dont think it'll be worth the hassles, just sell up and buy one already done!!

Thanks again for all your help!!

Anyone needs a new sensor, repco sell them i baught a ford EL one, got it for $85!

    • Go to SP mufflers and get the muffler of size you want and make a nice mid muffler. It's about that simple! I have 2x 3.5 Magnaflow straight through Mufflers and while it's pretty loud with the Varex open, it's quiet enough with the Varex closed. You can also buy off the shelf Magnaflow straight through mufflers as well. You also have a turbo to quiet the car down too. Don't overthink it. Buy my extra Magnaflow muffler sitting on a shelf doing nothing (buy it new, ignore this part)
    • Centre-offset muffler under the floor, same as stock. Just....3.5". The change from straight pipe there to centre-offset will mean that you need to remake some of the pipe (add a bend or two).
    • Hey guys. So my R34 GTT has a custom 3.5” exhaust (done by previous owner) with a high flowing cat, and then just a Varex cannon muffler on the back. The car does drone alot and is really loud even on highway driving just cruising, as you can imagine due to the Varex muffler basically being a straight through with the valve open. As much as i love a loud RB, it can be a bit much with no other muffling in line and just driving casually. I wanted to lower the volume output on the exhaust a bit, as well as remove the drone (probably a way to do both at once), and was going to do it all myself as I am a fabricator and have done exhaust work in the past, so the fab work isnt my issue, im just not sure on the right product or type of product to use to get the job done, and i doubt an exhaust shop would be wanting to help me as they wont be making any money from helping me, unless they supplied the product? Anyway any help or guidance in best way to approach this would be awesome   Thanks in advance
    • Meh, whilst the Honda is a "really" good car and has potential if you want to drop coin on, it was uninspiring for me to look at, but, it did serve its purpose and is now in the boys hands, his happy, his girl is happy, as she wasn't to keen on the noisy old Patrol, and most importantly, the Minister for War and Finances is extremely happy that her "little baby boy" (6'2 nugget who is currently training to be a copper, which will make 3 coppers in the immediate "circle of trust") has a well sorted reliable car that doesn't guzzle diesel Me, I'm more than happy with the NC MX5 that I replaced it with, it's a fun little car that I like looking at, like driving, and yes..... I do like the fact that the maintenance and modifications that I have done/will do are plentiful and relatively cheap, well........ while staying naturally aspirated slow that is, and that's all I really need for a fun little daily, I can rev the 5hit out of it rowing through the gears and never really break the speed limit  In saying that wicked word, "modifications", I've already ordered something for some noise and an additional "3 ish" horse powers, or whatever it gives, in the form of a header, and, a new set of "cheapo" BC coilovers that are already sitting in the shed waiting to get put in, I had the same BC's in my old NB and found they were fine for the street, hwy, and the occasional track days I did in it, they have 6kg front and 4kg rear springs which is about 10% stiffer than the stock springs which I found worked well for their price  I've also already been in touch with MX5 Mania in Dural, so once the header is on it will get a ECUTek RaceROM tune there (I cannot rev match for 5hit, and I loved the RaceROM rev match and FFS in my old 86 "RIP") In other, maintenance news, I put some new sparkler plugs in it, and have a new set of DBA Street series pads to put in over the next day or so, I'm running the DBA street series in the SS and Honda and really like them, they work great and are not dusty at all I've also booked in a few days leave over this weekend to give me 4 days weekend do some paint correction and give the leather seats some conditioning and interior some Bissell and steam cleaning OCD lovin', the carpet and interior looks clean, but from my experience with the Bissell IRT carpet, and the steam cleaner IRT trim, looks can be deceiving I've also found that finding a detachable hard top is proving problematic, the main reason why I didn't like the NC initially was the power retractable hard top that I seen them with gave the roof line a weird look, the detachable roof though looks good, and is a same shape as a NA/NB hard top, similar, but unfortunately not the same as it has different fixture point on the front, so fitting a easy to get NA/NB detachable hard top is no bueno New Old cars are fun, cleaning, hunting and playing around brings much joy How are your beasties going? Do you still have the Skyline with the LS???, or Barra??? that you were playing with
