foxyroadster Posted July 24, 2009 Share Posted July 24, 2009 I've got a 68 datsun I'm sticking a RB into or going to attempt to... I'm unsure on which one.. I've been looking at all of them and which one of them do you guys think might be better for a little car? I am wanting 300hp that has some reliability of a daily driver and I don't think it is too much to ask of any RB. I'm thinking I'll be best off with a RB25 with what I'm describing, I've searched around on RB's but feel free to school me some more so I can make the best choice for my project on the motor to buy.

jerryb Posted July 24, 2009 Share Posted July 24, 2009 You are right in track. The RB25 is a great deal and would easily provide that power level with stock internals and extra boost. Just search.................. Quote Link to comment Share on other sites More sharing options...

dwarlick Posted July 25, 2009 Share Posted July 25, 2009 What about an SR motor? Its gonna be cheaper and the parts are more readily available. I have an RB26 and they are great but come at a price. Plus you have to consider that the S30 engine bay was originally intended for a straight 6 and your car was designed for a 4 cylinder (I'm assuming).

Canadianz Posted July 25, 2009 Share Posted July 25, 2009 One thing to remember at the moment RB oil pans are very pricey as they are no longer available from Nissan. I have a RB25det with bolt ons and it is a ton of fun, if your doing the work it might be worth a RB26. These engines get pricey quick which is the major knock.... also buying some parts takes a wee bit more time than on other more mainstream engines. I say if you can find a decent price on an oil pan go for it ! Quote Link to comment Share on other sites More sharing options...

Plus you have to consider that the S30 engine bay was originally intended for a straight 6 and your car was designed for a 4 cylinder (I'm assuming). I would use the SR but what I want to copy requires an inline 6.. I just figure since I was looking at L28's I might as well just jump into something newer. I think it might have been what sorta was the tinkering that eventually lead to the beloved Z. http://www.datsun.org/fairlady/Oct2006.htm It has a link to the history of the Fairlady S In the GP-II Class, competing against the likes of the newly unveiled Toyota 2000 GT and the Cobra Daytona Coupe, Nissan revealed an exciting variation on the Fairlady theme. The Datsun Fairlady 'S' boasted a twin overhead cam, 6 cylinder, 12 spark plug, twin distributor, 2-litre engine, a whole year ahead of the launch of the single overhead 4-cylinder 2000. The takeover of Prince, with all the OHC expertise that PMC brought with them, undoubtedly influenced the development of this 'UY' engined prototype, not to mention the production Nissan/Datsun OHC engines that followed. As well as the prototype engine, the car featured lighter vented body panels, streamlined panels under the chassis, and Minilight style wheels. The doors had no handles and were opened from a recess in the door jamb. The rear arches were also cut away and flared to accommodate the alloy wheels. The 'S' still retained drum brakes at the rear. The Fairlady 'S' qualified a remarkable 1st on the grid, much to the excitement of the crew and surprise of the crowds. In the race proper, she competed well, until ignition problems caused her to retire after 36 laps of the 60 lap race. She was sadly never to race again, although the entry was a sign of Nissan's serious approach to track competition. At the time of writing, a Japanese SROC member owned the remains of a 'UY' spec. prototype engine, a truly rare piece of Nissan competition history. I'm in the middle of a frame up restore on the car and will be able to freely cut the body. I'm pulling the body off the frame be able to see about placing the motor properly and touch up rust spots. I'll have to double check but I think I'd only be gaining 100ish pounds by swapping to the RB over an SR as the R16 in the car is cast iron and weighs more then the SR. Currently with most of the parts for my car I'm looking at a weeks wait with shipping so this isn't my daily driver. Guess I'll have to make my own oil pan.
