Thread: 2_Liter_Turbo's S13 SR20DET Twin Scroll Build

  1. #1

    Talking 2_Liter_Turbo's S13 SR20DET Twin Scroll Build

    In the spring of 2007, I ended up buying a white 1992 240SX coupe for $500 to initially fix and flip to make some money, but I ended up liking it better than my red car, so I took my entire spring break and swapped everything over from the red car to the white car. It took me about 50 man hours to do everything. Interior, suspension, diff, transmission and engine, wiring, brakes, and all the other things were swapped over. It was a big undertaking!

    These were taken April 28th, soon after I swapped everything over from the red car.





    These pictures were taken May 12th of 2007 at the Redding, CA Drag Strip.





    The car stayed as it was after I did all the parts swapping for some time. I started saving and buying parts for the next step of my build. More power!!!

    Ordered some new goodies for the next part of the project.

    Kaaz 1.5 way LSD, ACT HD pressure plate, ACT 6 puck racing clutch, ACT Streetlite flywheel, and a new radiator (wish I would have just ordered another Koyo), because my koyo was damaged.


    Splitfire Coil Packs


    Tomei 740cc injectors, Tomei/Nismo adjustable FPR, oil filter relocation kit, Earls top mount turbo lines, Tial Q BOV, cheap catch can, Nismo engine and tranny mounts, and some other hardware.


    And where the money was spent! Full-Race twin scroll GT3071R, Full-Race twin scroll turbo manifold, Tial 44mm waste gate, and a Full-Race 3" down pipe.

    06-17-08

    Dirty motor




    Cleaned up a little, and with new turbo stuff mounted.

    09-10-08: Took some current pictures of what the car looked like.










    03-26-09: I got some new wheels finally!




    Then I installed some 275/40/17 tires on the rear.






    05-07-09 I finally was able to make it to a dyno!






    It was a mustang dyno and the elevation was at 4200 ft. I put down 342.5 whp and 334.6 lb-ft of torque! The stock cams really hurt my power up top!


    With this power, I was able to run an 11.95 @ 114mph with a 1.61 60' launch. That is my best time so far at the drag strip.

    05-30-09: I did a "photoshoot" down on treasure island in the bay area. My friend Bryan To shot all of these pictures. This is also how the car sat before I pulled the motor (again) for the current build.

    Now a little story: So I ended up buying another block to do my "build" on originally. I had it machined, and the rotating assembly installed (just the block), and then I installed the cylinder head and all the other parts I had ordered up to this point. The engine had scat rods, Mahle pistons, a brand new SR20DE crank, ACL bearings, Apexi HG, all the head hardware etc. I ran out of money towards the end of the build and stupid me cheaped out on the tune. I paid for my stock ECU to be modified and re-flashed for a tune capable of my modifications and boost parameters. The initial engine break in went decent, and my AFRs looked to be good (a little on the rich side except for when at 20psi and higher rpm). Well about 600 miles into breaking in the motor, the tune showed its ugly self and detonated badly and blew out the ring lands on number one mainly, but a little on two and three pistons. Number 4 was the only one still in great shape. I also had a lot of problems with the block sealing correctly with the coolant fittings that were pressed in the block. So I decided to scrap that motor, and am now currently building the original motor that I bought back in 2005. From now on, all updates will be of this motor.

    01-11-11: Brand new Greddy intake manifold!


    01-21-11: New CP 9:1 86.5mm pistons.


    02-10-11: Separating the SR20 that I bought back in 2005 for the first time! This motor had 140k miles on it from me alone, so with an estimated 200k on the clock after whatever miles were put on it in Japan, this thing still ran perfect! It had factory compression before being pulled, and the bearings look amazing after I pulled the crank. I've always used Royal Purple motor oil.



    03-02-11: Mazworx Tq Plate!


    WPC treated parts


    WPC treated CP pistons


    As of 03-30-11 (today): The motor is in the machine shop getting prepped for assembly. More updates soon!!!

    Well my crank scraper/baffle/windage tray setup FINALLY got here! Almost 2.5 months of waiting for this to be finished! Now it's off to the machine shop to finally get the bottom end machined and put together. More updates soon hopefully, lol.

    04-28-11: Got my head back from the machine shop. Got it resurfaced. They used a PCBN cutter setup (which is basically a diamond cutter) to get a decent finish to seal with a metal headgasket.



    They also installed my Supertech dual valve springs (I don't have a valve spring compressor), new OEM valve seals, and other spring hardware. They also cleaned it up a bit. Going to clean it some more before I install of course.



    Now I'm waiting for my test shims to get here (hopefully this week) so I can see what sizes I need to order to get the proper clearances for the Tomei solid lifters.

    05-08-11:

    Did a little work on it last week after work:

    Ordered a new set of Tomei test shims


    Grabbed my WPC treated (and modified for solid lifters) rocker arms


    Cylinder Head


    Installed test shims and rocker arms


    Installed cams to spec


    I then checked the clearances for all the valves, did the math, and ordered the needed shims to have .13mm of gap between the rocker arms and cams. Had to order 10 of the 16 shims from Tomei, the rest from Nissan. Waiting on those and my new cam cap bolts, and the head should be ready to go.

    Picked up my bottom end today! All the machine work is finished, crank is in with the scraper, Scat rods, CP Pistons (WPC treated), ARP mains and ACL race bearings. I'll have lots of updates over the next couple weeks! Couple pics before I start working on it:

    By the end of last night I got a few things done. I should get a ton done today!

    Oil Pump Prior to assembly:


    Timing hardware installed:


    Timing cover, water pump and crank pulley lightly installed. Torquing down after "red death" drys, lol. The crank pulley will get torqued when the head is installed along with the rest of the timing gear.

    Yesterday I didn't get a lot done mainly because I also bought a new tool box and was dividing my time getting that sorted and working on the motor, lol. Anyways, here are a couple pics of the progress:

    S14 oil pickup installed. This was a big PITA with the scraper in the way...


    I got the cylinder head torqued down on an Apexi HG with ARP head studs. I'm always nervous torquing these, ha ha. Cams are also installed with the rest of the timing gear and CAS.

    Update: 06/25/11

    Here is my upper oil pan that had to be modified to fit the ARP mains and crank scraper.





    Here is my progress by the end of today:


    -----------------------------------------------------------------------

    Update: 06/26/11

    Got some more work done today. Turbo/Manifold combo is not bolted down tight, it's just on there so I can build turbo lines. I need a 45 degree AN fitting (ordered tonight) to finish that up so my lines are all set up. I'm now running an S14 water neck, so I was able to delete the hard line at the back of the head as well as the long SS line that wrapped around to the turbo from the hard line. I can also now run a normal heater hose to the heater core rather than the mickey mouse crap that most SRs run due to the hard line pointing the wrong way normally.




    -----------------------------------------------------------------------

    Update: 09/11/11

    Engine is done. Going in the car today!









    It's finally in the car! Lol




    -----------------------------------------------------------------------

    Update: 09-22-11

    Worked on some IC pipe routing today. Need to cut some more piping tomorrow to continue...

    Thanks! I am done posting now, lol. I will do my best to keep this thread updated. As you can see from the dates on the posts, I tend to take my time, especially now, because I want to do it right (I'm also super busy, so things take a bit long, ha ha).

    Fantastic posts! And a great build. Looks like you're to the point you can pull that motor in your sleep. :D

    Keep us updated. It'll be fun to see what the new motor will do when you finally get it like you want it.
