After months of wanting a new project I finally figured out one that would fit my needs. AWD was looking real good but after duing research on it the 60’ and 330’ wasent really the same as a straight RWD. 240sx was looking good. but there are some weekness’s such as the head and IRS. seems like the only problem with the fast240s out there is the head and there is not really a “good” fix to the problem. and everyone knows IRS is weeksause for drag racing. Chrysler Conquest is going to the new build for '09. solid rear axle, 4g63 goodness and possibly and auto tranny to hold ALOT of power discuss… pros cons? ---

hmmm should be fairly stout. have seen a few out there. what axle you thinking about using? are you running a class or just building for fun? thoughts on rear suspension? ---

What is your end goal for times? What class are you looking to run? Solid Axle is no doubt where it’s at, thats why I was contemplating building the Datsun 510. After seeing what Hybrid did with the IRS on the 240 with a properly setup suspension made me think that it might not be the biggest concern. The 4g63 is a great motor, but I am sure just like the sr20 it has its quirks. The SR20 head issue seems like its pretty much resolved with the latest combo from mazworx/hybridynamics. ---

that was the reason why we started with 510 use the nissan titan rear end and should be golden. already four link from the factory so easy to build adjustable arms. but the grey area was if a carb car could be fuel injected and still run the class. no real answer so more less scrapped that idea. ---

I will sell the 510, right now I have no plans for it especially when I just sunk more money into the 240. If you want to run a class just double check that you can go carb to fi. I don’t see a place in the rule book that it specifically say you can not. ---

here goes a random thought. look into small or mid sized import trucks from the 90’s. something has to have a solid rear but who knows how strong it would be. then just swap a nice turbo motor in. ---

I double checked the rule book. trucks are permitted to run turbo street. here are the pieces that scared me when thinking about building the 510: > ENGINE: Reserved for 4 cylinder, 2 rotor, 6 cylinder entries equipped with a turbocharger, superchargers, a nitrous oxide system for a total of up to two power adders. Engine must be the some make as vehicle racing. Bolt on modifications only. Aftermarket cams, headwork, valves, cam gears and other internal modifications allowed. Motor-swaps allowed. Approved aftermarket > blocks allowed. No air-cooled entries. Wet sump oil systems allowed for competition, no vacuum pumps of any kind allowed for the oiling system. So that pretty much says anything goes as long as I am using the same manufacture for the engine and chassis. > INDUCTION SYSTEMS: Any commercially available induction may be used, but stock > configuration must be retained. Ex: Fuel injected entries must remain fuel injected, with the same > type of injection used as delivered stock. Now this statement is pretty vague but it would lead me to assume that you have to stay carb if you started carb.
