It made mine run richer.. A Lot richer. hence slightly more fuel consumption and lots of pops and bangs from the exhaust.

One quick question.... Anyone..

I heard Matt's 268rwkw RB25 R32 idling and I noticed that the fuel pump was a little noisy (what mine sounds like on a hot day) BUT.. My fuel pump only operates when you touch the accelerator not when idling.

Mine is setup so that it runs Inline as it is an external pump.

Is that a normal type setup? When you touch the accelerator it activates the bigger pump?

yeah, i would also like to know how loud the 044 pumps are, are they really that annoying? like say compared to the annoyingness some ppl find of loud exhausts on the freeway.... i.e. not the same loudness, but would it be that annoying daily driving?

edit: also if possible, could you give a description of what it sounds like? maybe even a wav or mp3 file would be nice :D

Hmm shit...

alright...because ive been getting round 230k per tank since having it put in...though i also had the timing put down at the same time due to pinging (thought the old pump was on the way out), so i thought that was the main cause of power loss...

So, can we adjust the pressure without a regulator?

I was looking to get 1 of those r32 chips in the 'for sale' section, which is ment to have new fuel maps...will this also help?

    • Hello!  i just finished manual swaping my r34 skyline with a r33 rb20de box(RB71C)box  When the car is running it squeaks crazy loud and it was smoking from the gearbox area. The gearbox is fine it was tested. The clutch slave cylinder seems like it doesn't fully releases the clutch. I want to ask if this noise is from the throw out bearing or could it be the clutch assembly or disk att.xFliq87Gzw6kImKBVqDebXkj0fBqymk0JaYeP3_3SlM.mp4
    • A few small updates since the previous post and lessons. I decided to do a little interior light upgrade on the 110. I quite like the iilumo items, even if they're a bit of a premium over other brands. You'll also note the Stedi Fogs, that will go into the S15 fog lights as I needed to match the bulbs since I got the new ones earlier. I hope they fit as the body is quite a bit longer than your normal bulb.  Annoyingly, I managed to trip the fuse, which normally wouldn't be an issue until I located the fuse. I can't say I've ever come across this. I had lucked out that someone nearby had a spare, but oddly enough Toyota dealerships seem to keep this in stock. I ordered some to keep in my stash and as luck would have it, someone else nearby tripped the same fuse so I passed on the favour.  I also did a little service on the 110 ahead of some additional work coming up. It's been annoying that Goleby's stopped carrying this particular HKS filter for the 110, so now I need to keep them on order from Japan. I also took the opportunity to install a bash plate and number plate riser. The plate riser is such a cheap but nice fix to help really tidy up the car. I'm tempted to now also replace my headlights, on this car. Both items were from Project Aero.    I also needed to replace the rear tyres on the 110, and after trying to get it aligned learnt that I need to replace some bushes in the front end, so that's next.  Closing out this update with a nicer picture as always! 
    • Yeah mate, never miss it.
