Not enough oil pressure from hydraulic lifter gallery(being low pressure, as opposed to getting feed direct from main oil gallery).

I think the internal vct mod is a bit of a hit and miss some say it works others say it doesn't.

All I can say is that it didn't work for me, and its a head off job to drill and tap for a vct feed line.

Take a risk and find out if it works for you :P

So you ended up wanting to go the 35R? What made you change your mind? Just curious...

Ive currently sold my GTX and just purchased a 35R to throw on there.

currently she only revs to 6500 rpm as anything over that it just stops making power, though still enough to run a 12.1 on 18 inch ling longs.

With the 35R on there I can rev it just that little bit harder and gain that extra 1000 rpm. +fix the vct issue and I am back to where I started in terms of response.

Its win win, fix vct and get similar response to the gtx without vct + have that extra 1000rpm head room to get down the 1/4 quicker.

      Another "where do these lines and plugs go" RB25DET question

      By thatjawncrazy · Posted

      GTSboy, thank you again. i’ve been reading all the other SAU RB25 vacuum line threads and you have the utmost patience for people asking “where do my vacuum lines go”. it’s appreciated. i did also enlist a few other RB guys local to me.  i would like to run 5 to 4. turbo pressure side to wastegate actuator. i would like to run 3 to 1. power steering air valve line to intercooler outlet. (this is how it was previously). i was told 2 is the bleed port for the boost solenoid - which i’m not running - so should be capped.   anyone see any problems with that?

      Ethanol Content Sensor - Always at 11%?

      By Kinkstaah · Posted

      So yes. All of them. Something like 98% of all fuel in the USA has 10% ethanol: https://afdc.energy.gov/fuels/ethanol-fuel-basics It's labelled as like, AKI, 87, 91, 93 with an E10 or E5 or E15 label on the pump. At a certain point, it's not just "E10" instead of 91. It is 91, 95, 98, and all of them have 10% Ethanol in them. You can also get E85 and E30 which is why you do see some people rolling around with E30 tunes in them.

      Blue slip

      By Stringycheese · Posted

      Thanks for the response. This is an 04 EP3 Type R. JDM spec. Fairly certain they're just basic BC racing coils. I do plan to keep as the ride quality on stock I've been told is pretty meh given Sydney roads. If I were to go down that avenue, does NSW require them to be a certain spec (close to original) etc?

      Blue slip

      By PranK · Posted

      I've had two super conflicting experiences with blue slips. My 30 year old E39 waltzed through with no issues but my brother in law was knocked back on 12 y/o 3 series due to wiper blades and some cracking in a control arm bush.  What kind of coil overs? Do you want to keep them after?  If it was me I'd get some dirt cheap shocks and springs from eBay or scumtree. Not ideal but will get you over the line and might even be less than $1k.
