Up for sale is this Datsun 1200 fastback which is in amazing condition.  Check out the For Sale section for more infomation.  Happy Friday.

I know… I know… Many of you have been waiting patiently to hear what has been going on with this 350z project car.  Now I am here to feed you a just a teaser of what is to come!   From the graph below you can see that the car made 500whp and almost 500wtq at 15lbs of boost on our terrible CA 91 octane fuel.  Remember that this car has a built automatic transmission, with a drive train loss of over 20%.   That puts the crank horsepower rating at or above 650hp!!!

If you are wondering why the car hasn’t made more all you need to do is consult the dyno graph again.  Just as the torque converter locks up the numbers seem to go flat.  This is because the car has a mere fifteen degrees of timing in it.  When fully tuned this car will run close to 18 or 19 degrees of total timing which will smooth out the graph and bring this engine to life!

REMEMBER THIS WAS JUST THE BASELINE RUN WITH THE NEW TURBO KIT

After more timing is added and the air fuel ratio is adjusted, we expect to see the graph continue to climb into the atmosphere.  Only time and tuning will tell, and for that you will have to wait just a little bit longer.  Drool away.

I’ve added a sale section (top, center) to the blog that will allow us to offer cars and other parts for sale to all of our readers.  I will post a message like this on the main page whenever I make a major addition or change to the items in the sale section.

Right now there are two cars for sale with more things to come!  If you would like more information on any items in the ‘for sale’ section or if you would like to post an item for sale contact Rob through rob@zcargarage.com.

FOR SALE

That’s right!  Valentine’s day is hear already which means that the trip to Hearst Castle with the Z Owners of Northern California (ZONC) and the NSX club of America (NSXCA) is taking place this weekend.  Hopefully the event will have a nice turnout even though the rainy weather and the Valentine’s weekend hotel rush are trying to put a damper on things.  A couple of us here at ZCG were able to get in at the last minute due to a few cancellations.

I will be updating the blog with photos and what-not by early next week so that everyone will be able to participate in the good times.  DRIVE SAFELY EVERYONE!

Yesterday we installed a set of Stillen high-flow catalytic converters (HFCs) onto the 350z that received the Injen Intake system and the Unorthodox Racing lightweight pulley last week.  We’ve seen how these HFCs have improved the power band in the past on other cars but it’s always nice to back up good results.  Again, this car is equipped with a Nismo exhaust system, unlike the other car with these mods which has a Bassani exhaust.

The Stillen high flow cats are a high quality piece but as with all exhaust modifications where the stock catalytic converters are removed we were interested to see if there would be any increase in exhaust rasp.  As you remember this was a small issue that we had to resolve on the red HR car that had the Bassani true dual system with an x-pipe.  The Nismo system is much different, it comes from the cats into a 2.5″ to 3″ Y-pipe (stock is 2″ to 2.5″.)  From there is a single 3″ pipe, with resonator, back to a factory style (but larger diameter) rear muffler.

This car with the HFCs installed exhibited almost none of the rasp that has become associated with the dual exhaust cars.  While the exhaust note was very nice, you can see from the dyno graphs that this car was a few horsepower short of the Bassani 350z.  The cars were dyno’d on different days but all the results are SAE corrected to get them on as even a playing field as possible.  In their uncorrected forms, both of these cars are putting down over 300hp to the wheels. Very impressive.

Below you can see the run comparison with and without the HFCs.  The Stillen cats gain around 10hp and 10lb/ft of torque at the wheels throughout the rev range.  That’s certainly power you will feel on the road which makes this change almost mandatory from a performance aspect.

Here are the graphs that show this customer’s entire power gains over the past week or so and the comparison between the this car and the earlier Bassani equipped car.

We are trying to get the ball rolling with a header and camshaft comparison for the HR engines and maybe an turbo install in the near future to show all of you what is really possible with all available modifications.  We can’t wait to make more “RELIABLE” power from the HR series.
