Welcome to Forge Racing

Welcome
This site will be used to chronical my many adventures and misadventures with my 1972 240Z tube frame racecar as well as my 1979 280ZX streetcar. I have owned the 280ZX for about 5 years now. I love to modify and generally tinker with it. The 240Z racecar has been mine for about 5 months now but it shares most of the same components. L28 engine, B box 5 speed transmission. 3:90 rear end and there are small differences. I will cover these in the categories for each car.



I am also involved in several local clubs that promote racing and skilled driving events. Among those are the Oklahoma Z Car Club [OKZCC]. Also I am a member of the NEOKLA SCCA we hold local autocrosses and Road Rallys throughout northeast Oklahoma.

Dave Martin having clutch problems.

A little background: Dave is also building a GT2 280Z racecar. About 2 weeks ago I drove down to Henrietta OK, to help him put the engine and transmission in the body. Since then he has found and resolved an ignition/timing issue with a missing screw in the distributor. Today I called Dave to see how things were progressing and he said not so well. His clutch does not seem to be completely disengaging. Interesting, because when I put in an aluminum flywheel in the 280ZX about a year ago, I had all sorts of problems with the clutch not disengaging. So I suggested that he might want to get a bar clamp and place it on the clutch fork and tighten it down (this is what I did) and see if the clutch would completely disengage. If so this leaves two possibilities the clutch fork rod is the wrong one and is too short. Or the release bearing is too short. He mentioned that he had heard that there were 2 different release bearing sleeves one for a 225mm clutch and one for a 240mm clutch. Just coincidently I had the transmission out of the racecar and I could get to a known 225mm release bearing sleeve. I also had the one that I was in the 280ZX 2+2 when I was having all of the clutch issues after the aluminum flywheel install. So I measured them side by side with the digital calipers. Look below.
225mm release bearing sleeve so the coupe is longer

240mm release bearing sleeve and the 2+2 is shorter.


Don’t you love it when it takes you about a year to positively figure something out?

Tulsa Boneyards, and Z Legends


Tulsa Area Chapter Z-heds doing their own repair or restoration projects know the value of a good salvage yard. In Tulsa, the common knowledge for many years was to seek out Henry at Ace Auto Salvage for used parts. My first visit there, however, was not pleasant. Just my luck Henry had retired and sold the salvage yard to someone who turned out to be less than interested in Z cars or customer service. I did not go back there for a long time. Then, I got a tip from OKZCC member Chuck Wilson who referred me to the personal salvage yard of Peewee in nearby Turley. After finally finding the place, I noticed something vaguely familiar while rummaging around the yard and talking with Peewee. Turns out that Peewee used to work for Henry at Ace and had bought all the Zs and ZXs and moved them to his own place. Peewee had my business for more than a year, until I got a tip at the monthly Tulsa OKZCC chapter meeting that Archer Auto Salvage was under new management the legendary Henry had bought it back. I believe persistence and loyalty, even if it is to someone you’ve never met, will eventually be rewarded. On my first visit back to Archer Auto Salvage, I was greeted by a scruffy version of Santa Claus who wanted to talk about Z cars and racing. Yes? at long last I was face-to-face with Henry. Each return trip to the Z-car salvage yard over the next two years felt like a family reunion. Henry would perch nearby to chat and watch me strip some part or another from a donor Z. Even though he claimed to be too old to run the yard and was supposedly retired, he always seemed to appear (seemingly out of nowhere) to talk Z cars and share tales of his racing at Hallett in the 1970s. I had mentioned to Henry that I was trying to save enough cash to invest in building a Z racecar, but the goal was still a ways off. I never gave much thought to that particular conversation until November 2006 when Henry met me as I got out my 280ZX at the salvage yard. Still want that race car? he asked. Sure, I said, and for the first time in my life, I actually had some money saved. Henry gave me the number of Tulsan Larry Childs who had raced at Hallett in GT2 and was thinking of selling his tube-frame 240Z. Childs had bought the car from Henry in about 1992 and converted to a sole-purpose competition machine. It was rough, but essentially ready to race. I looked it over and less than a month later it was mine. I did some bodywork on the steel fenders, cleaned up the hood, put on a fiberglass front bumper, and painted it with Duplicolor Fleet White (the cheap stuff). Fellow OKZCC member John Lucas machine buffed the entire car for me and vinyl decals gave it the finishing touch. This is the car that won the Sports Competition trophy at the Darryl Starbird car show in Tulsa last March, and that I drive in NEOkla Region SCCA autocross competition. I’ve also driven it at high speed at Hallett until I used up third gear on my last outing this past May. More visits to the boneyard are in my future, and I look forward to more visits with Henry.

Fuel cell failure 05-22-07

Found the fuel cell leaking

So I drained the fuel and pulled the bladder


Turns out that the bladder was made in 95 should have been replaced in 2000 and 2005
