Don Oldenberg is still making and selling the Nissan Comp pan. Design Products Racing.

Despite notices on the web site and in other places, some folks are a little upset that betamotorsports.com is no more. Remember, I sold the company back in March. I'm doing fine working at Benton Performance (Benton Performance) and we do work on S30s. I've kept the Betamotorsports Facebook page (http://www.facebook.com/pages/BetaMotorsports-LLC/143989191670) and will update that from time-to-time. And, don't worry, I'll still be posting trite and obnoxious things on this forum.

Not true with wheel bearings. They should be done with the front wheels off the ground. There is a very specific process outlines in the FSM from proper setting of the front wheel bearing preload.

Take $1,250.00 or more off the price for a sunroof. Myself, I wouldn't buy a sunroof'd S30 unless it was for parts or as a race car.

The ring gears in the R180 are 10mm until sometime in the mid 1980s when they went to 11mm. There's a post on Hybridz where I list the exact date of changeover. "K" housings normally contain a two pinion open diff although some 4 pinion open diffs were used, although I don't know the application. All the 720 truck, Maxima, and 200SX R180 K units I've seen were two pinion open diffs.

The 3015, 3016, 3012, 3013, and 3038 are all the same shock. The difference part numbers are for the gland nut and the spacer (if any).

Its not a bolt on. There are slots cut in the cylinder head intake ports to allow the injector flow to atomize properly in the port. That's assuming your engine is carburated.

1970 and 1971 S30s are not particularly rare. On the local craigslist there are 8 for sale right now.

I used to charge $600 per side for a complete floor pan install and there were no gaps, no need for bondo. For that price I also cleaned the underside, painted with high zinc rust proofing primer, sealed the seams with body seam sealer, primed, and painted both inside and out. You got what you paid for if you paid $600 for both floor pans.

Race 2.4Ls that ran in GT2 back in the day made over 360 horsepower. Spin fast and you can make power even without a lot of displacement.

Reducing lift increases fuel mileage. It takes energy to lift the front and rear of a car and that energy comes from the engine. In a corner at the traction limit an additional 20 lbs. of less lift on the back can be the difference between the exiting the corner under control or having the rear end break loose. Turn 9 at Willow Springs will teach you that. Formula 1 teams spend tens of thousands of dollars to generate an additional 10 lbs. of downforce.

That was over 10 years ago. Tokico appears to moving away from their aftermarket shock business. They have not done any R&D on vehicles made after 2009 (check their catalogs) and really screwed up with the last distribution agreement with Belshore. I used to be a Tokico WD but cancelled that agreement in 2011 after they outsourced all their assembly, warehousing, and distribution to Belshore (who happened to be another Tokico WD) and I started receiving product with missing and wrong parts. I spent over $400 in FedEx overnight shipping costs to make things right for my customers and Tokico/Belshore told me "tough luck." Things went downhill from their and Belshore declared chapter 11 in December 2012 to get out of their agreement with Tokico. Belshore's claim was that Tokico USA had vastly overstated product sales and Belshore was stuck with a warehouse full of Tokico product that wasn't moving. Tokico has been saying they have their distribution problems solved but vendors still can't get product.

Staggered for show, square for go... :-)

Normal. Alignment specs are for flat roads.

G-Force used to build a nice T5 style transmission. Contact Taylor Race Engineering in Plano TX.

42.3%, 18.726%, and 89.001%.

Yes. The triangulated front STB I built for my racing 240Z let me increase front spring rate by 50 lb.in. Before the brace I was spring limited in front. Any increase over about 275 lb.in. showed no change in lap times. Adding the STB let me increase the rate and drop lap times. Adding additional reinforcement let me add another 50 lb. in. in spring rate up front up to 375 lb. in. in the car's final iteration.

60F is generally not considered a cold start. 12 or 13 at most as mentioned above.

Webers do not have a cold start choke. They have a cold start enrichment circuit and no fast idle. There's a little lever that gets pulled via a cable that increases fuel. What that AFR is depends on how you've tuned the car. It can be anywhere from 14 to 1 to 10 to 1.

M8 x 1.25p.

The same as it affects other rwd cars.

A suggestion... try to move away from three bolt flange connections. Slip fit with collector springs, bolted tabs, or t-bolt clamps saves weight, increases ground clearance, eliminates gaskets, and generally has a better flow.

Its all TIG welding. Very purdy...

A couple nit picky items. Car bumpers are generally not designed to be part of the safety system that protects the passenger, other then as additional crush space.

Also, make sure you're comparing parts within the long nose R200 and the short nose R200 models. There are differences.
