Hi,

For my next build, I would like to go to dry sump but I have a few questions :

A. I would like to keep the AC, so it looks like it's possible to mount the oil pump below the alternator.

B.1. I would love to find room for the oil tank in the engine bay (by removing/reallocating the fuse box) however I'm afraid of the efficiency of the oil tank as it will not be a bottle design ?

  2. or in the driver side front bumper, but same as above + quite annoying when refilling oil or even checking oil level...I only saw some R35 with this location (no R32-R34)

Conclusion it looks like the best area is the trunk or the rear seats which is quite annoying for a "street" car

C. How can I know how many oil liters the engine needs per RPM ? I'm looking into the selection of the correct pressure of my oil pump but I don't know how to do it ?

D. Goal is 600-700WHP, street and track days (no drag or launch control to save the transmissions) and since my front trans already broke (due to incorrect ratio => previous owner). I know what's involved if it brakes again

D.1. Considering my application and power level, do you think I should go with a kiwi oil pan (with separate front diff case) ? or it's not likely it will brake and I'm better putting the money somewhere else. "Money is not the issue". The question is does it worth it ?

 

Thanks for your advices !

Hi octane do a kit that puts the pump under the alternator but you can’t use an ls1 style alternator with it

you can put the tank in the bay it just requires cutting a hole in the inner guard for it to fit through

Thanks for your answers guys !

 

@r32-25t do you have any pictures of such installation ?

Yes I saw the kit, I'm going with a R35 GTR alternator with a custom bracket, I think it will be okay

 

Yes it's not recommended to put the tank below the pump so I will not considered this option

I need to keep the ABS location free if I need to put it back for autorities...

 

I'm still looking for answers to questions C, D1 (and D) 😛

      98 R34GTT 4k engine stumble

      By JC71 · Posted

      forgot to mention that when it does this it does not kill the engine, but I have not kept the pedal down long enough to let it, as I see no reason to beat up on it as its got to be something simple, small and dumb causing this.  And as soon as I let off pedal, the engine returns to its normal super smooth operation and rpms re-stabilize quickly, once below 4k.

      98 R34GTT 4k engine stumble

      By JC71 · Posted

      neither stumble or cut really seem to be an appropriate term....hard to explain its like a rev limiter but at 4k, but it violently shakes engine and entire vehicle as the rpms will not rise over 4k, even with slow acceleration. as soon as it hits 4k, it sounds like entire spark is lost entirely. plugs were 1.1 which I used as such, but later put in new plugs gapped down to .8 changed back after issue arose when I replaced the coils, still does it with either plug gap...damn and it was all running so good.

      Why am I hitting a power wall with my stroked RB25?

      By TurboTapin · Posted

      Oh how times have changed! I actually lean it out relative to my water/methanol injector duty cycle. The methanol adds a lot of fueling and you can then lean it out even more due to reduced knock.

      Yeah my thoughts are the same, a well thought out WMI setup, would be slightly ahead of just straight E85 and you're also chemically intercooling the charged air, dropping it even further. This is why you need to add so much more fuel as soon as you spray. I remember someone taking me through their set up before (Dennis, has a R33, lives around Cabramatta - no idea if he's still around on this forum). He would target AFR 10:1 on 98, then as WMI ramped on, AFR would lean back up to 11:1. Amazingly, he did this all through his PowerFC, a relay to cut power to his EBC solenoid if there was not enough line pressure on his WMI kit. And of course, if there wasn't any boost made above gate pressure, you wouldn't be accessing the load cells with heaps of timing for WMI. One downside to that rudimentary setup, once the WMI came on, the EBC would unleash the dragon, and of course all the timing. Tyres would fry lol.
