stony Posted November 21, 2015 Share Posted November 21, 2015 Well, after pounding the calculator trying to figure out how I was going replace the rb with a 2j.... it just wasn't adding up. was going to cost way to much to transplant the 2j in the place of the rb. SOOOOOO I did some research and picked up a bone stock 5.3 truck motor just in case. After I did the math and sold the rb.... I was able to get everything I need to put a turbo 5.3 in the car and have a bunch of cash left over ;> Specs stock 5.3 truck motor with 40k on ticker. chromoly push rods BTR trunnion upgrade stage 2 BTR turbo cam titanium springs and retainers. Melling hi volume/pressure oil pump I also pulled pistons and checked bearings. Damn things looked like new and measure good so I reused and increased the gap on the top rings for boost. All this will be mated to the same drivetrain I had in the rb Combo. Powerglide, ford 8.8, currently 4:56 gearing but will be going to a 3.70 Do to the way the trans tunnel and chassis was built around the RB the ls motor will sit a little more forward then a typical install which will make getting the BW480 in there a challenge.

~KnuckleDuster~ Posted November 21, 2015 Share Posted November 21, 2015 Why the change in direction? Just bored? Quote Link to comment Share on other sites More sharing options...
stony Posted November 21, 2015 Author Share Posted November 21, 2015 Well for me to continue down the road I was going I would need to dry sump the rb and its stupid expensive. I will more then likely need to do the same thing with the LS eventually but they have much better off the shelf pans that work well. also when its time to go dry sump the ls is a lot cheaper to do. And again for the same reason I was considering a turbo NA 2j.... I cant find junkyard motors in the use for 300 bux. Quote Link to comment Share on other sites More sharing options...
dexter72 Posted November 21, 2015 Share Posted November 21, 2015 Dang stony, 2jzs are in yards out here all the time. We have $69.00 all you can carry Junkyard days out here. I carried tons of parts out of the yard on those days. Doing my build thread now. Its not anything close to an epic build. Junkyard low budget special.

stony Posted November 22, 2015 Author Share Posted November 22, 2015 LS is the same here as 2j. got a complete longblock with 40k on it for 400bux. it was just the 2j was going to eat up too much funds in cams springs, ect ect. LS is done and should be good for 1000hp. and all the parts I put in the motor cost less then a set of cams for the 2j. Quote Link to comment Share on other sites More sharing options...
Ryan Merrill Posted November 22, 2015 Share Posted November 22, 2015 I switched the direction for teh same reason. The transmission were expesive as hell. W58 wont hold the power, the 6 speed costs more my my car. Quote Link to comment Share on other sites More sharing options...
ktm Posted November 22, 2015 Share Posted November 22, 2015 Welcome to the dark side as they say. I understand the appeal of the 2jz and rb motors, but people need to remember that the LS or even truck motor (5.3) has LITERS of displacement on those engines. The LS/truck motors can then have forced induction on top of their displacement advantage. People pursue build routes all the time for illogical reasons, when logic prevails base displacement is always the best starting point.

Z-Gad Posted November 23, 2015 Share Posted November 23, 2015 I hear ya Clint!!I love the aesthetics and exhaust note of the 2jz, but like you said, you can have the entire j/y 5.3 motor together for the price for a set of cams in the 2JZ...If money were no object, Might be a different story...but money is an object Quote Link to comment Share on other sites More sharing options...
stony Posted November 25, 2015 Author Share Posted November 25, 2015 Well I have most of the core support prep done. Not sure how I'm going to do it yet but intercooler and radiator will be as far forward as possible. Quote Link to comment Share on other sites More sharing options...
stony Posted November 27, 2015 Author Share Posted November 27, 2015 Well Other then not being able to use the old RB mount tabs (wasn't planning on it) the CXracing 240sx single turbo header fits like it was made for the 240z. My motor is mounted a little more forward as mentioned previously and maybe a little higher then most but I still think if it was mounted in the normal JCI location the headers would work.

stony Posted November 27, 2015 Author Share Posted November 27, 2015 Drivers side plugs are gonna be a BIATCH! !!! Will be easier to pull header to get at plugs. Also stock wire will not work. Will need some serious heat protection for the boots also. Quote Link to comment Share on other sites More sharing options...
stony Posted December 27, 2015 Author Share Posted December 27, 2015 Well I have made some progress. Mig skills are not the best but they will work. A little grinding and seam sealer and will look good ;> at any rate. Lower Bar and intercooler mount done. upper radiator support bar (removable) done. just need to make the tabs for the upper intercooler mounts and the radiator mounts. Then on to the turbo hot side.

stony Posted January 3, 2016 Author Share Posted January 3, 2016 Some progress pics. I have the Driver side hot pipe tacked and ready to weld. Need to fab up passenger side, waste gates, and downpipe. going to be tight in there when its done. Quote Link to comment Share on other sites More sharing options...
JustinOlson Posted January 6, 2016 Share Posted January 6, 2016 Looks good. Where are those headers from? Quote Link to comment Share on other sites More sharing options...
Mikey303LSZ Posted January 6, 2016 Share Posted January 6, 2016 stony - Thanks for sharing the photos. This is helpful providing ideas for my turbo upgrade. I was just in the garage thinking through a radiator/intercooler support and came across your post. Keep them coming... Looks good! Quote Link to comment Share on other sites More sharing options...
stony Posted January 6, 2016 Author Share Posted January 6, 2016 Justin, They are CXracing 240SX headers for their Ls swap. I flipped them to give me more room. Only bad thing about them is it makes changing plugs a bear. Quote Link to comment Share on other sites More sharing options...
