In most states in the US registration is not a problem. There are only a few that require an emission inspection and almost none that require a safety inspection any longer. There are many Big Block Vegas and Pintos (not sure if you had those chassis styles in Australia or what they might have been called) and having a 500 to 600 HP supercharged or turbocharged whatever is only regulated by how much you are willing/able to spend on your car. It becomes a little bit tricky in those few states where emission laws rule our lives but even in most of those states that is a regional thing (certain counties, etc) and imaginitive folks seem to find a way to license their cars. In the US if you wanted a Viper V-10 in your 1200 the only thing that would stop you is how to make it fit. (Might I suggest a Toronado transaxle ane rear-mid engine positioning?)

Blue printing doesn't do much to add power but it does add to reliability. Blue printing is the optimum machining of all of the components in the engine (bringing them to the specifications that were on the original "blue print" of the engine that the factory engineers designed) Engine components are like anything else in a production car, there are tolerances that are considered acceptable. Rods may vary in weight by a few grams, ports may have irregularities and core shifts in the castings, the flywheel may weigh a pound more than the original design intent. Bringing all of these parameters to the "blue print" will make an engine more durable.

Performance enhancments like porting, different cams, higher compression pistons will increase the performance more dramatically.

An A15 running to 10k rpm is probably a 10,000 to 12,000 project, billet crank and rods, custom forged pistons and a cam that probably has differing specs from the one that you have (I said probably, don't know for sure) as well as perfect balancing and a highly refined GX head to top it off. Roller rockers and the aforementioned double or triple valve springs, and an aluminum flywheel are probably on the menu as well.

Good luck.

Wow. I got all excited and tried to access the classicdatsunracing (dot) com web site. It says that it has bee deactivated.

Somewhere, and I thought it was on this site, I remember seeing a B210 race car that was yellow with what I'm going to call "Krylon Blue" stripes over the top. It was a good looking car and I am just trying to find that picture. Does this ring any bells?

On my 1200 racer I used 240Z front springs (cut roughly in half as I recall) and stock rear springs. I used a stock front bar and had done the items that are outlined in the handling book from Nissan/ Datsun that you can download on this site. The only place that I deviated was the installation of a rear panhard bar that was adjustable. This permitted me to raise and lower the roll center to compensate for immediate conditions. The combination of the adjustable front camber and the panhard bar allowed for about the amount of adjustment that a novice with one friend at the track for crew can accomplish and I found this to allow the 1200 racer to handle quite well. A car had to have a bunch bigger tires and 200+ more horsepower to leave me behind in the truly twisty stuff.

The car in the second video looked like a Legends car. Made by 600 Racing in Charlotte area NC. USA. Had the wrong wheels. There are also a series of homebuilt cars that are similar that are known as Dwarf Cars. Just about the same (the Dwarf Car guys are going to jump me for that statement) in specifications but the Dwarf cars are a bunch quicker as the guys get to do their own suspension tuning and make more power vs. the Legends which is a spec series.

The first vid is what drifting should be about, not making smoke and burning up tires.

The Church Lady

A fellow went to church on every occasion possible. One day a new lady came to church and sat in the pew directly in front of him. She was a particularly large lady. Whenever she stood for the prayers, singing or what have you, the fellow noticed that her dress was always lodged between the cheeks of her bum. This went on for some weeks.

One day the fellow could stand it no longer, when everyone stood for the singing he reached over the pew and gently tugged on the bottom of her skirt to dislodge it from it's location.

The next day, at the Doctor's office the poor chap had to relate the whole tale to the Doctor when asked why he was beat to a bloody pulp.

A few weeks later a friend came to church with our fellow. He was also a very helpful sort and when everyone was standing for the prayers and singing he noticed the way the woman's skirt lodged itself. He reached over the back of the pew and tugged on the skirt to release it from it's location. Now, our poor fellow who was a regular looked at his friend and said "oh no, she likes it that way" and proceeded to tuck it back in with his fingertips .

The coroner asked his friend, who had only attended church just that once, what happened

Well, now I went to look at it again and it's gone. Has been removed.

matty, look at your pm

I have certainly considered it. But that would require me to change the body on my car to either a MX5 or a MX3. I like the B13 body better than either of those options.

Nissan body = Nissan engine where I want to race it.
