That looks like a good option, probably best to install it during the initial swap though.

Toddcod

Didn't Flynin miata cut most of theirs away? Or are you placing the motor higher and using stock oil pan.

UrbanSoot

im using boss frog swap. no need to cut oil pan with it.

sutol1

perhaps no need to cut the pan but definately do a baffle. I have read so much about the issue I bought the V8R pan baffled with remote filter. Took two versions to get the fitment right but now it is in and looks great. I like how it was engineered.

I had an Improved Racing baffle ordered until I decided the V8R pan would be the best route to take. I'll need to build a skid plate like Lee's before the car hits the road though!

I'm thinking about getting a V8R oil pan and pick up snout for my conversion. I don't track my mine but I would like to head off a bad problem and make my conversion a little nicer at the same time. Why did it take you two versions? Do you like the remote filter arrangement? Any surprises? How long did it take to swap out the pans? Any thoughts would be appreciated. Thanks, WWW.

They had some issues when using a non stock gasket, as well as a few fitment issues on the very first batch. I'll be able to tell you if the newest batch has any issues in the next week or two

I'm also partial to the remote filter setup, as it allows us to put the filter anywhere we'd like (I'm putting mine up front next to the oil cooler)

Another possible solution would be to get the C5 batwing oil pan. It should fit using the rearward mounting position (on the Boss Frog, not sure about the V8R). That's what I'm going to use, and another guy on M.net is going to as well.

I put the improved racing baffle in David's LS6 miata (4sevens.com) and he has tracked it several times with no issues. That's on a stock f-body pan.

4sevens.com

I've got trackmate videos/logs to prove it. Long sweeping turns with lots of lateral G's with no problem.

LS2 V8 Miata

The Current OEM LS2 Corvette pan has NO Bat-Wings and NO ISSUES with G-Loading / Cornering starvation due to it's excellent new (2006 and up) internal baffle design. there is still plenty of room on both sides of this pan to run exhaust and ground clearance is about 1-1/2" Better than F-body pan.

Additionally, I milled off the horn-like, projections on both sides of the oil level sesnor and installed a flat plug in the passenger side, sensor hole, giving even MORE clearance for exhaust routing.

My experience anyway.

chpmnsws6

I'd double check the oil starvation comment. C6 LS2's have problems, and LS3's REALLY have problems on the track where the C5 LS1's didn't have many.

LS2 V8 Miata

There's a ton of Corvettes running here locally C-5s & C-6s, LS1, LS2 and LS3s (roadracing) on 4 different courses / tracks, with The Bondurant's School that's 5 courses and his Vettes & CTS-Vs. ProAutoSports here in the Southwest also runs the Bondurant Corvette Challenge Race Series and nobody is complaining of "oil starvation" problems that I've ever heard.

Hard to imagine that with the LS2 and 3's windage tray, pick-up tube located in the dead center of the engine and the baffles running both directions (see 1:03 to about 1:10 in the LS2 video) in the LS2 and up pans, there would be any wide spread, design problem. I've been in Vettes pulling over 1.25 lateral "G" without incident. The fastest ALMS prototypes on race compound tire pull under 2 "G"s on average.

If I had engine failure, especially on a rebuilt / modified engine, I'd look at something the builder might have screwed up first. My experience with hundreds of engines is that human failures happen more frequently than mechanicals, and humans like to blame mechanicals so they don't have to build it again, correctly, at THEIR expense.

Just my experiences and opinions.

Just OTHERS experiences...... Since I'm too poor to own/race a C6

LS2 V8 Miata

Noted in the Forum discussion you posted, one guy talking about a "Handful" of LS3s starving, noted they were ALL prepped by the same guy and others weren't having any problems. (Hence my comment about "Builders" problems versus Mechanicals)

I wasn't trying to give you a hard time, I can't afford a C-6 either, hence an LS2 Miata. I've had the benefit of working for all the sanctioning bodies involved in roadracing regionally and oddly, my son-in-law has had a LSX engine business, with a large part being 100K+ Sandcars, mainly running LSX motors.

These Sandcar LSXs are not only mounted in the rear, they're turned around back-ward to mount to a trans-axle in almost every instance. Not only are Lateral "G"s a potential problem, (see pix) but huge, long duration Wheelies can smoke a motor (again see pix) The best oil pan like we used in Jeff's Car twin-turbo LS2 stroker is a GTO. The GTO's deepest part of the pan (Sump) is in the Front. On a turned around LSX in a Sandcar, it's now deepest in the rear, great for oiling consistancy during long, crazy wheelies. No broad base LSX oiling problems with these cars as long as factors are taken into account.

The Sandcar in the fore-ground is a 650 RWHP LS1 and Jeff's twin-turbo is over 1000RWHP. This is a liitle of where my first-hand, extreme conditions with LSXs comes from.

Don't worry about ribbing each other a bit as it keeps discussion alive..... And teaches us pups a thing or two

On the flip side, can even a prepped miata pull the same G's as a prepped C5-C6? 325 gumball tires, 3000 pounds, low slung, great suspension, and even better aftermarket support on their side. My C5 with 255/295 Kuhmo MX's had about the same suspension mods as the miata does (C5 actually had less), but it used to rip your face off going around on/off ramps. The miata just doesn't get to that point before it breaks loose (205 RT615's).

I know these are quick little cars, but can they be THAT quick?

Keith

The MX is a better tire than the RT615. Can a Miata corner like a 'Vette? Dunno, never worked on the plastic cars.

I'll probably make a copy of that improved baffle for my MG project. I'm using an unmodified F-body pan in that build. Thanks for the pics.

If anyone wants a C6 LS2 pan, we have a bunch at FM along with windage trays and baffles. Brand new, they're take-offs from our crate motors.

chpmnsws6

How do they compare to the 225 RS3's? Wish I'd known the MX's were better..... I've been thinking the 615's were better and wondering why in the world they just weren't holding. Sure they are smaller, but the car is also just as proportionally smaller!

I wish a Hankook or Kuhmo would make a 245/45/15 in the RS3/MX flavor

LS2 V8 Miata

Yup, you know it seems like we're All always chasing after Tires, Manfuacturers and Ever Changing Tire Sizes.

I've had 16" rims on my car for years and have run Michelin Pilots, Dunlop Sport 9000s, Yokohama Pradas, Kumho Ecstas, 712s and MXs and currently ToyoT-1s 225-40-ZR16 and the battle always seems to be Finding Size availbility first, performance level (stickyness) and then Price.

I've Shopped extensively too, even world-wide and it's always; "Iffy"!!

Keith

Grassroots Motorsports does testing of the "UHP" class of tires on a regular basis. The RT615 has been eclipsed. All of their testing is done with the same tire size and wheel width, as once you start messing with that you open up a whole can of worms

Toyo always seems to have the widest variety of sizes. Most manufacturers stick to the standard ones.

Racers choose their tires first, then find out what the best size to use would be. Finally, the correct wheels to fill the hole in the middle of the tires.

chpmnsws6

What tires do you recommend for a street/auto-x car?

They need to last 10k miles (1 season)

Looks like GRM's results show the Kumho XS being the quickest, so how would the 205/15's match up against 225/15 RS3's?

Keith

On the V8s, I've been recommending the 225/45-15 RS3 simply because there aren't many other choices in that size, and it's the largest size you can easily run on a Miata. The Toyo R1-R might be worth looking into as well. The upcoming TR Motorsports C3M 15x9 is shaping up to be a good value in wheels too.

chpmnsws6

"Sadly" I already have 6 15x9 6UL's sitting here waiting to be wrapped

Keith

That is a shame
