pcs_russ Posted March 6, 2009 Share Posted March 6, 2009 Some info for you RB20 guys. This is a dyno of my brother's 240sx with an RB20. 100% stock engine, GT30r turbo, 440cc injectors, ebay manifolds, 3" exhaust, front mount intercooler and Electromotive TEC3. 20lbs on pump gas running in the high 10's afr and 18 degrees of timing. Going back this weekend to hit 400rwhp. Russ Quote Link to comment Share on other sites More sharing options...

turbotalon1g Posted March 14, 2009 Share Posted March 14, 2009 That looks like fun. Dizzle don't worry, just get to work. lol Quote Link to comment Share on other sites More sharing options...
sqweekykneecap Posted March 14, 2009 Share Posted March 14, 2009 haha. that is impressive. im still goin crazy over either 20 or 25!!! only got 2 weeks to make the biggest decision this year! Quote Link to comment Share on other sites More sharing options...
Bat Fastard Posted March 14, 2009 Share Posted March 14, 2009 Dizzle, 300whp should be easy to get. The first pull on the dyno we made 318. That was with less than 5min of tuning that Russ did just to get it to run. Theres lots of room for improvement at its current tune. It should get 400 to the tires or it will die trying. (then we can put the RB26 in it that is collecting dust over in the corner of the shop) sqweekykneecap, flip a coin and go for it. The RB20 is a ton of fun in the 240sx, the 25 would just be better! This RB20 has been beat on pretty good by both Russ and myself and it hasn't brooke yet. (trust me we tried) Almost everyday it gets run, it's banging off of the rev limiter in 1st and 2nd, and keeps coming back for more.

RB20DET_Z Posted March 15, 2009 Share Posted March 15, 2009 Nice numbers. Gives me confidence Ill hit over 400whp with my setup. I look forward to seeing your final numbers. Quote Link to comment Share on other sites More sharing options...
pcs_russ Posted March 16, 2009 Author Share Posted March 16, 2009 Still haven't had a chance to return to the dyno but after some tweaking and turning the boost up the car is going pretty good now. Does nice 60mph burnouts. Running 22lbs of boost now on pump gas. I wonder if it'll take 25? Quote Link to comment Share on other sites More sharing options...
RS Speed Posted March 18, 2009 Share Posted March 18, 2009 nice setup but what's with the catch tank... it isn't doing much there, turbos still eating the oil. Quote Link to comment Share on other sites More sharing options...
Evan Purple240zt Posted March 19, 2009 Share Posted March 19, 2009 Classic catch can fail! Quote Link to comment Share on other sites More sharing options...
pcs_russ Posted March 19, 2009 Author Share Posted March 19, 2009 Your correct, it won't do squat. It's there for looks. Russ Quote Link to comment Share on other sites More sharing options...
Careless Posted March 19, 2009 Share Posted March 19, 2009 Your correct, it won't do squat. It's there for looks. Russ it could be re-routed to work though. put the filter on the valve cover port going to the turbo intake pipe, cap off the ports that join the two valve covers, as one will be intake-air, and one will be pressurized-outlet port. keep the one going to the catch can, and send a line from the catch can back to the intake pipe. the Bernoulli effect created by the turbo's compressor wheel suction will pull vacuum and suck the oil from the valve cover into the catch can (take that filter off the catch can), and will separate the air from the oil inside the catch can if there's a substrate for it to fall onto and suspend it. Am I right or is this incorrect? that's how i've seen it set up. Quote Link to comment Share on other sites More sharing options...
jerryb Posted March 19, 2009 Share Posted March 19, 2009 Thats how I have mine set up and it does collect oil. I use a clear oil compressor air filter and it works great. A question aside...do you run a blow through MAF? it could be re-routed to work though. put the filter on the valve cover port going to the turbo intake pipe, cap off the ports that join the two valve covers, as one will be intake-air, and one will be pressurized-outlet port. keep the one going to the catch can, and send a line from the catch can back to the intake pipe. the Bernoulli effect created by the turbo's compressor wheel suction will pull vacuum and suck the oil from the valve cover into the catch can (take that filter off the catch can), and will separate the air from the oil inside the catch can if there's a substrate for it to fall onto and suspend it.

RS Speed Posted March 19, 2009 Share Posted March 19, 2009 hes actually almost got it hooked up half a$$ correct lol. for the easiest fix, I would say slap that little filter from the catch tank on the intake manifold side valve cover which is currently going to the catch tank. then move the catch tank to the other side of the engine bay, inline from the exhaust side valve cover fitting to the turbo intake pipe fitting and you done. Leave the U bend hose where it is. in all honesty you have all the parts including the lines to hook it up right, you should just hook it up Quote Link to comment Share on other sites More sharing options...
pcs_russ Posted March 21, 2009 Author Share Posted March 21, 2009 A question aside...do you run a blow through MAF? No MAF at all. Just Map. Russ Quote Link to comment Share on other sites More sharing options...
jerryb Posted March 21, 2009 Share Posted March 21, 2009 How???...Mega Squirt? No MAF at all. Just Map. Russ Quote Link to comment Share on other sites More sharing options...
RB26powered74zcar Posted March 21, 2009 Share Posted March 21, 2009 How???...Mega Squirt? I think Russ is running a Tec3. Quote Link to comment Share on other sites More sharing options...
Evan Purple240zt Posted March 21, 2009 Share Posted March 21, 2009 The way that catch can is plumbed is definitely for looks. At least you not running a MAF, which would leave you with unmetered air. At least connect it between your intake pipe and valve covers so it collects something. Evan BTW; Didn't mean to threadcrap, nice looking car.
