oh, and the only two expensive things left to do on my car (other than the front diff), are the FMIC (which I'm covering with water/meth injection)...and brakes. I've got my heart set on Brembo monoblocks front and rear, 343mm rotors so I can continue to use 17" wheels (buying a set of 18" is highly unlikely for me, unless a set falls into my lap - the cost versus benefit - simply slightly more bling appearance, just doesn't work out). Anyways, the Brembos...the calipers are grey. The car is grey. It's just....destiny

It's also ten thousand dollars!

But truth be told, Endless rotors, stock calipers, APP braided lines, Endless pads, and Motul brake fluid go a LONG way in improving brake performance. I've never been in a situation on the streets when I needed more. But when I eventually run sanctioned time attacks, more braking power would be useful for late braking and trail braking.

Nice technical pics, keep them coming! Me likes precision work, thats what I learned...

Have you drilled out the sump oil return holes

OCD is good, man. Just what you want in an engine builder.

They are the row of holes under the drive shaft tube in the sump.

Yes but the Tomei baffle covers the front of the holes so oil cannot splash up them when they are enlarged .

If the modification is not done the strainer could end up pulling air, as the baffle lid does not have enough holes in it for the oil to flow back into

kismetcapitan · 4th July 2008, 05:13 PM

is this a mod specified in the Tomei installation instructions? Odd that they put two holes on the front (left side of the pic) upper deck of the baffle, but none on the right sloped part. Wouldn't oil just flow under the top part of the baffle and through the trap doors underneath? Or is the problem that there are no trap doors on the right (rear-facing) part of the underside?

A fair number of people use Tomei oil baffles, I think I'll start a separate thread about it.

kismetcapitan · 4th July 2008, 05:35 PM

ok, I nicked this pic from RHD Japan:

here we have the lower assembly. The right side would face the front of the car, and the left the rear. Just one trapdoor to let oil in. I can see the notches for the ribs in the pan.

here's Tomei's illustration:
Oil lubrication

so would holes be drilled in the upper plate to assist oil drainage from the rear? That would make sense if the single trapdoor wasn't enough to flow enough oil from the rear of the sump into the "box" where the oil pickup is.

I'm straining my eyes at the small picture on the Tomei website - it looks like there's a "wall" perpendicular to the ribs that might get sealed off when the upper plate goes in? I wonder why Tomei didn't think that out.

Yes they even spec the size to drill out too

I see now. Damn, need to check on this.

Here is a picture of the holes in mine

not to threadjack your sh!t kismet, but...

i was going to use the tomei baffle on my r34 build, but instead i got my hands on a second hand nismo baffle that I understand might offer a slight advantage over the tomei.

does anyone know if a similar modification to the pan must be made for the nismo baffle? i didn't get instructions with it since it was second hand.

kismetcapitan · 5th July 2008, 08:51 AM

I guess it depends on how it installs, see if the baffle impedes oil flow back into the "box" - if it does, drill accordingly!
