Bolt color just states LSD. You have to take cover off to see gear ratio. It is stamped on the ring gear. Subaru stopped putting tags on in mid 90s.

JohnK most Subaru's share the same diff if it is an all wheel drive version. Impreza WRX, Forester are the most common. They come with a variety of gear ratios 3:54 3:90, 4:11 and 4:44. For naturally aspirated engines especially the S2000 engine the 4:11 or 4:44 are the best. If you do more track days and less driving on the road the 4:44 certainly gives you alot of grunt out of the turns. It will rev to about 4200 at 70 mph which can become a little annoying on long drives at steady state speed. It doesnt bother the motor but the engine noise at the level can wear you down after 200-300 miles. Millenium Auto speacilizes in Subaru salvage they are very knowledgeable about the diffs. http://www.y2kimports.com/contact-us . Chuck Spera has a 4:11 diff with Quaife diff in it that he is intrested in selling. He will be in Michigan thru Christmas after that he will be in Florida for a few months so if you are interested let me know fairly soon I dont know how much he wants for it. I have a few diffs here I have one brand new in the box that is an LSD but I dont know the ratio. I have about 10 others but I need to pull the covers all of them and get the ratios. General rule of thumb on Subie diffs if the diff cover bolts are gold cadium plating they are limited slip. If they are plain steel bolts they are open. I also have a chart that I will try to attach. I have it for about 10 years so it is a little dated I think it stopped in 03 but it will give you an idea of ratios and LSD and which car has what. With your inboard brake setup your axles should go into any of the R160 diffs that accept axles. Some diff have a stub axle that comes out of the diff those wont work.

Xcarguy the R180 is dimensionally the same. The ring gear section is bigger but they should interchange The axles will be different for sure the STI is heavier. We change the center section, axles and rear uprights. I am the new owner of World Class Motorsports. I bought it from Brian a few months ago.

Sounds like it will beca fun car. I don't know if the R160 diff will hold up to the supercharger. We used the same diff on our first supercharged car we were making about 300 rwhp. We had to change the 5 times in one week with broken pinion and ring gears. You may want to consider cryo treating your diff parts to help strengthen th some. Or change to the R180 out of the STI Impreza. You may also find the first few gears will have slot of wheel spin. We changed to 3.90 which works good with the lower end grunt of the Rotrex. You will love Rotrex power is very linear the unit is very quite. Are doing air/air or air/water intercooling? Sounds a great project and a lot of fun. I like the color too it looks good with black wheels.

RossD I am very familiar with the performance benifits of ethanol. 7evin and I built his car specifically to run on E85. We researched it for over a year and have been running it for 3 years. You will never get the same mileage running ethanol as you do gasoline I dont car how well you groom the ECU. It takes 40-50% more fuel running on E85. It has performance benifits because it has a very high octane (113) and that is why we can run 15lbs of boost with 11:1 CR on E85 and it makes great power. It does have a induction cooling effect which helps on forced inductin engines. It does come at a cost. We had hard anodize all the aluminum components in the fuel system. The fuel cell in normally aluminum. E85 corrodes the aluminum. We had to find a crosslink polyethaline tank to use for a fuel cell. The fuel pump is double the size needed compared to when you run on gasoline. It also has to be hard anodized. Fuel injectors need to increased to supply the fuel required. We are running 4x1000cc injectors on a 2.2 l motor and we are close to running out of duty cycle on those. The modern flex fuel cars have the provisions to deal with the alcohol. They have plastic fuel cells, plastic fuel lines and sensors that detect the alcohol content to adjust the ecu. Those that buy e85 for the modern vehicle have no concerns with flex fuel vehicle unless it sits for over 90days. The fuel will start phase seperation after 90 days assuming you put in you vehicle when it was fresh. If you bought your fuel from a station that doesnt move alot of fuel the gas can be bad when you put it in the tank. This doesnt even bring up the problem fuel stations are having with the ethanol eating the varnish off the walls of old tanks and pumping into your car. This will get better as time goes on and the tanks eventually get cleaned. There is a big concern that the underground fiberglass tanks will start to leak because the alcohol can disolve fiberglass tanks. You can see this in the boating industry where there has been a massive problem with the fiberglass tanks built into the bottom of the boats are leaking due to ethanol in fuel. My intent on bringing this up is there are a number of guys here that run aluminum side draft carbs and aluminum fuel cells with aluminum fuel lines. They have mechanical fuel pumps with a rubber diaphram or electrical with rubber parts that will eventually fail when exposed to ethanol for extended periods. I assume a large majority of the members here also have string trimmers, leaf blower, lawn mowers and snow blowers, generators, atv's and motorcycles that can impact. Talk to any of the mechanics that work on any of the above items and they will tell you the devestating effects of E10 gasoline. That is assuming you are getting E10. I stated in the first post we have found E50 in tanks that were labeled E10. Matter of fact a mojority of the spots we tested ranged between E10 and E15. Seafoam is a product orignally developed for the boating industry. The engineer that gave our class has been working with ECHO for 30 years. He stated that the Seafoam has showed the best results in all their testing. Echo spent millions of dollars working on the problem over the last few years.

I agree that not likely with those tires but the potential is there.

Looks like EPA is trying to ban 100LL by the end of 2011.

It is basicly like a powered parachute with a drive transaxle. It varies at little with the mast pole to hold the chute up for quicker take off and landing. It must give it a little more wind stabilization too. Powered parachutes dont handle winds of more than 8-10 mph from what I have read. I wanted a Buckeye Powered Parachute years ago, but I live in TExas and the wind always blows. After looking at the website they use a subaru 2.5l on the standard version and turbo version with 300hp is an option. It uses a CVT trans and weighs less than 1000lbs so 3.9 sec to 60 sounds plausable. Looks like fun to me.

here is a picture of a newer style bracket on a car. It is 3/16 metal with an 1/8 metal rib that runs along the back of the brace and is tig welded on.

7evin and I used the Gerbing heated motorcycle jackets too. They have a rotary style thermostat to adjust for comfort. Like Budlite suggest we just used a heated liner that we wear under a insulated jacket with wind resistant shell. It keeps the whole body warm. Just a good insulated set of gloves and a helmet and you can motor all day in sub 20 weather if you wish. I found I had to keep the thermostat in low for most conditions 35 and above. It uses a simple twelve volt plug that we had wired by our seats and it draws little current, just sit down put the belts on and plug into the car and you are nice and toasty.

MisterMike what do you do when you store your car for short periods?

Kitcat from what I understand is that Stabil does nothing for ethanol fuels. Stabil forms a barrier that floats on top of the fuel that helps reduce the the octane vaporization of the fuel. It helps keep it from going bad by providing a layer between it and air. The engineer doing the seminar stated Stabil was becoming in effective with new fuels.

We have a much better bracket now. I will send you a pic.

I attended a class a few weeks ago about the damage ethanol causes in small engine and how to avoid it. It had been easier in years past to just buy the 91 or 93 octane and avoid the 87 which usually had ethanol mixed with it. With the new fuel incentives that push the mixing of Ethanol in the fuel it is now showing up in the super unleaded tanks as well. I had always assumed that the fuels that say they are 10% ethanol were a calculated mixture. I started doing some testing in the last few weeks and have found as much as 50% ethanol in the 10% marked pumps. Super Unleaded have had from non to up to 15% ethanol. The state weights and measures dept that monitors pumps at stations says that they do no fuel quality testing. They make sure you get a gallon when you buy a gallon and that is it. There is no stae or federal agency monitoring the actual percentage of the mixtures being dumped into you local gas station. You can buy a tester for under 10 dollars check your favorite fuel spot and see how it stands up. So what does this mean for our favorite fun transport. To start off it is recommended that you run a tank of fuel at least every two weeks. Current gas shelf life is 90 days. After 90 days you will begin to have phase seperation the ethanol seperates from the gas and doesnt just remix with a shake. Ethanol is very hydroscopic so will pull moisture from the air thru the fuel vent and put water in the fuel. When they water sits in the fuel tank, fuel lines, side drafts carbs corrosion sets in at an aggressive rate. The Ethanol is also corrosive to aluminum and other metals. Fuel systems that have ethanol must be hard anodized or plastic to keep the corrosion at bay. If you have side draft carbs and your car sits for a few months over the winter you are very likely to have a poorly running car when you start it in the spring if it starts at all. The fuel will corrode the bowl and eats the brass jets in the carb clogging it or changing the orfice sizes for incorrect fuel ratio when you finally get it cleaned out. I have a friend that is the local professional lawn retailer for west Texas and is one of the top Echo dealers in the state. He has seen string trimmers and blowers that have blown the engine in 1 or two weeks because the home owner did not read the manual and put E10 fuel in and scored the piston and cylinder from the ethanol washing the oil of the cylinder. Most new equipment has a ethanol sensor in the tank. If the sensor changes color your warranty will be voided. What are your options? for all your small engines you can buy a fuel made by VP racing fuel that is call SEF (small engine fuel). It is available in quarts and 5 gallon it is available as a 4 cyc or 2cyc with the oil already mixed in 40:1 and 50:1 ratios. Your cars need to be filled with fresh high octane fuel with Seafoam additive in it. I would recommend testing the fuel before putting in the car before storage to make sure it is ethanol free. you have access to aviation fuel 100LL can be used. I wouldnt recommend it if you have fuel injection with O2 sensors the lead can ruin the sensor. The VP fuel is a pure 94 octane gas with a long shelf life up to 2 years. The bad thing is the cost. Here a 5 gal bucket is 47.00 for the four stroke fuel. 57.00 for the 2 cycle. A 54 gallon drum here is 405.00 so you are looking at 9.20- 9.40 per gallon for real fuel. Not a cheap option but it is better than ruining your carbs and dealing with poor running conditions. There is several days of reading on the net if you want to research it on your own.

The bottom bracket usually breaks does yours have the T style bottom bracket?

Brian gave me a pile of T shirts he had made a while back and I thought I would pass them on to Ultralite owners. I have 4 large Ts in black with the yellow logo on the front. I have five smalls with 3 with logos on the back and two with logos on the front. I have two mediums with the logo on the back. First come first served. Shirts are free just pay the shipping. I think USPS has flat rate package for 4.95. I can take paypal or send me a check or Money Order. PM me for the details.

RNR working on cd fenders and fiberglass. We have better fender brackets that are very strong. Send me a pic of what you have I will see what style you have.

All Ultralite owners or other guys that are using the s2000 engine to power your ride of choice. I have found a nice oil pan baffle made by ENDYN . Larry did research and testing on it for several years and seems to help reduce the chance of oil starvation in sustained long turns. Larry is legend in the racing world and is an expert Honda engine builder. If he says its good then you can bank on it. I am going to be purchasing several sets of baffles to keep in stock. It is easy to pull the pan on the Ultralite take it to a local welder and get it welded in. I have several spare pans that I will go ahead and weld baffles in and do some type of exchange with you. Price will be 299.00 + shipping for the baffles. If you want me to weld them in I can do it for 340.00 + shipping includes the baffle. Just send me a good pan in return.

It's is a drawer slide. I am changing to extruded aluminum slides it should be more sturdy and easier to mount.

Ultralites have adjustable pedals on them.

Very funny , but sadly mostly true.

If you travel frequently what is the effect of multiple exposures to the radiation of the scanners. Is it equal to 50 x rays a year? The long term effects of multiple radiation doses are pretty well documented. I don't fly frequently a few times per year not a big deal. If I travelled two or three times per week then it might be a different story. I also have a huge problem with the approach used on small kids. I train my kids no adult is touch you in that area. If they do kick the he'll out of them and run. I agree with Benjamin Franklin who said those who give up freedom for security deserve neither.

I always have enjoyed his videos. My son found this video that is pretty amazing feat by a 4 yo.

7evin has something similar in his car. He has a switch on the dash. In the gas mode lower boost less power. In alcohol mode more boost more power about 100 up more. The extra wheel spin comes with both modes.
