rswilliams Posted March 24, 2009 Share Posted March 24, 2009 I just found a complete jdm RB20DET with trans, comp, and harness for $1000 on craigslist. The guy was planning on putting it in his 240sx, but ran out of money and time. Does that seem like a deal I should jump on? Here are my questions. Would the RB20DET be a good choice for my 300 - 350rwhp goal? If I get it, I am planning on adding the ebay top mount exhaust manifold, with full 3" exhaust all the way back straight mufflers and no cats. also an ebay intercooler kit. Fuel system will be custom fuel cell forward. Only other mod will be a bigger turbo a little ways down the road. What HP should I expect from this? how much boost would the stock turbo support? It seems that parts wise, I can get most of what I need for around 2k. That leaves the management system and injectors. I am still in college, and on a budget, so need to keep it as inexpensive as possible. Megasquirt interests me, but doesn't seem to be a good choice with the RB engines. If I just add the manifold and intercooler, would the stock cpu work ok for the time being? What other reasonably priced systems would work well. Or, after I make my mods, can I get the stock cpu reprogrammed? All in all, what would you guys expect this setup to run me in parts if I do all the wiring, and fabrication?

RS Speed Posted March 25, 2009 Share Posted March 25, 2009 Rb20 ecu is easily programmable so that would be your best bet for fuel management once you are ready. Changing the manifold and intercooler wont need a tune so you can roll around on the stock ecu for the time being. Save up for injectors, turbo and a tune. Should get you to 300whp no prob.

RB20DET_Z Posted March 29, 2009 Share Posted March 29, 2009 I love my RBz. No regrets. The RB20 will last forever if you take care of it. Quote Link to comment Share on other sites More sharing options...
