16 Year Olds RB25 240z

[Mark Maras]

 Oh. how I wish there were Z's around when I was sixteen. I would have had one at any price. After thinking about it tho, at that age and always loving speed (mph) it was probably a good thing that I started with drag racing. I undoubtedly would have crashed AT LEAST one Z. While I'm reminiscing, @jchoi have you considered driving school? Not the ordinary kind. Most sports car racing organizations and tracks offer driving schools, classroom and on track experience. Probably the most fun and the best money I ever spent on my Z.

Mark you are true speed freak! I used to be but when a 400lb motorcycle would get close to 200mph I knew my brain couldn't keep up with that and bought a dual sport DRZ 400. 80mph tops!

I'm still alive but crippled up as hell from all the wrecks I've had so I agree and highly recommend some driving training from Someone. That RB motor in a 240 is going to be rocket and as much as love the 240 they are not new enough to handle curves at speeds that motor will put out.

@siteunseen that does sound like a good idea, I used to race go carts when I was younger and did appreciate my coach teaching me alot. A refresher and some classes are hopefully in line sometime in the future.

Ok 930 I got in on this a little late. I too am an aspiring engineer so I get where you are coming from and like most others am quite a bit older than 16. 1st the metalwork, Harbor Freight sells an affordable sandblaster since you did disassemble about 60% of the car and it's not too late to do the job all the way. 2nd kudos to you for even buying this car considering the spaghetti bowl that wiring harness looked to be. 3rd you probably won't end up keeping this car due in part because of your age and if you turn out to be a successful engineer you will be making enough money to go out and but the latest iteration of the 911 or 458. So it may seem like site users are being overly critical because we plan to KEEP our cars. Most of us probably don't use them daily but they can be used daily which is why you may have gotten some unexpected feedback on your fuel cell. 3rd, here's my take on the fuel cell, I wouldn't go that route because it holds less fuel and it raises the C/G (center of gravity). Raising the C/G can alter the handling characteristics of the car which could put you in a dangerous situation under spirited driving conditions or even normal driving conditions depending on road surface conditions.  No one here wants to see anyone get hurt or worse. It is your car do what you want with it. Experiment, that's what engineers do, try out new concepts and ideas. You are beginning with a relatively light (weight) platform. It is very easy to try and reinvent the wheel so to speak and overpower these cars and most of us have seen it done before with not so great results. Just remember, racing is meant for racetracks not public roads so decide for yourself if you want a racer or a machine you can drive everyday if you choose to and look damned cool while doing so. Judging by the posts to your build most just can't seem to figure your rationale with certain mods. When I saw the harness I couldn't see your rationale for even buying the thing but I'm sure many thought that about me when I bought my 1970. Carry on young man but read, read, read. Invest in a sandblaster. You will be glad you did. Much faster than abrasive disks and wire wheels and much more thourough also. GOOD LUCK!

@esmit208 thanks for the advice. Its a lot to take in I don't plan on doing much racing but I am looking for something more connected to the road. And for the sand blaster, what type of compressor are you using to power it. I know they can't be powered by the cheap harbor freight ones.

Believe it or not the sandblaster cost me $30 and I spent another $40 re-installing the plumbing. The previous owner was ready to throw it away. COMPRESSOR was bought from a friend who owns a shop in the neighborhood 60 gallon capacity. Compressor cost me $200 and I bought a new motor for it $110. I sort of fell into these two items but a fellow enthusiast pointed me in the right direction. 60 gallons is enough to run any air tools. The sand tank will hold about 125 psi at least the manufacturer suggests no higher than that and the 60 gallon will take it well above that. Sand will also expose any weak spots that wire wheels and abrasive discs won't. Good luck

If you can get to Long Beach for the JCCS you'll see a number of Datsuns with RB swaps. Might get some good ideas.

That is for the tip. I didn't know about that but it's seems like a great idea.

Its been a while but my engine finally came in and the car is mostly prepped for it to be dropped in.
The engine is going to stay stock for a while so I can build into the power later is needed. I also have most of my roll bars installed at this point.
The welds came out pretty good for me.
I have the oil pan for the rear sump conversion and my wiring harness of the way. The engine should be in next weekend hopefully after I fabricate some engine mounts

Welds came out nicely indeed. Just out of curiosity how much the the roll hoop weigh?

[jchoi]

The main hoop came in about 20ish pounds
