    Project 240Z Turbo ITB Install

    in Nissan L6 Forum

    Posted

    Thanks Pete.

     

    I just emailed SDS since I noticed the site had eliminated many of the **SDS Top Tuners** from the dealer list and experience with my setup for the second set of eyes I need.  They said: "Many shops have gone out of business in the last 5 years. Nobody near you who I could recommend. If you have a wideband, we can help you with specific problems. If you have a hot cam and ITBs and are trying to drive on the street, tuning will not be easy." Awesome!! :icon50:

    Thanks again Tony for everything as you always shed your realistic light on everything. Yes it was only one dyno session but man did that really hurt my ego and all the work I thought i did correctly. I'm sure it's something in the wiring, the brain has been sent out and has the latest and greatest firmware etc in it. I think it boils down to the harness I made while having the right intentions I could be the cause. 

     

    I've had a few people contact me on here after my posting and I told them all what I have invested and I agree it would be foolish and start over. I just wish I had another set of eyes to look at it or get the boys from the north to come and help sort it out... I am so close its not even funny which is the sad part!

    As far as I can tell, the only reason to stick with ITBs is to have something that's different from most other cars. In my book, that's not a great reason.

     

    Join the pack of l28et owners who rarely complain about their cars, and stop feeling like you're missing out on something. You've been at this long enough, and if someone else wants to carry the torch of ITB/SDS for awhile (and pay you for the privilege), I say let them.

     

    That's how I feel Jesse, you can see how far this thread goes back...

     

    If they are running well, why change? Slap an HKS Type2 on there and follow the logical progression of the build.

     

    You aren't making any more power now over a custom plenum N/A Motor...

     

    Once they're set, they're set. Giving them up now for a manifold that flows what...maybe 190cfm per runner at best...

     

    You just wasted all that time!

     

    Stay with it, and more power at lower boost. Watch the threads...it's boost pressure (the Corky Bell Approach) that causes difficulties in a turbo build.

     

    A good lowing head and good cam makes killer power at 8psi, half the power most others. Make doing the "maximum boost" program.

     

    Then again, if you make a custom intake...oh, waitaminit...

     

    You are three bolt on parts from going turbo: a turbo, an HKS box, and a turbo manifold. Retune and run.

     

    I've done it for years. People at MSA one year said "wasn't this car turbocharged for the autoX yesterday?" It was, but in 45 minutes it wasn't anymore. Changed over the morning of the show. And with EFI it's even easier...no jet change required!

     

    This sounds more like a failure to grasp the basics of the project than a failure of the individual components. I don't know what SDS you have, but there are plenty out there running just fine without headaches, same as Megasquirt, MOTEC, Emerald, and for that matter ITB's.

     

    If you have issues it's likely form basic things overlooked or improper procedures. I don't know. Many times its misguided efforts and unrealistic goals. Like putting ITB's on a cast-piston N/A Motor with no cam. Terrible parts mismatch. On a turbo, the ITB's flow difference over the stock manifold makes for a big power difference at the same "plenum boost" as the stock manifold setup.

     

    Flow matters more than boost. High flow turbo engines (low boost) run into less tuning issues than mega boost engines making the same power.

     

    No, you don't need it. But you really are willing to toss out all the time you put in to get it "right" and start over with everything new?

     

    Having others tune? There is investment in personal learning in a project like this. If you abdicate that, you invariably end up disappointed with the result.

     

    Thanks for your words of wisdom as always Tony.  I'm running the EM-6F (coil packs and hall sensor off a custom BHJ pulley. 

     

    Look like they have already done the HKS style box.. :)

    You know, Big-Phil comes to mind, because his friend Chris (who I believe is a member here) owns a blue S30 with a turbo L motor. At one point Chris made 402hp at 17psi while Phil made 342 at 25psi. Phil seemed to run into problem after problem. Phil, as much as I love him, was kind of cheap about certain things. In the end he probably spent as much on his L motor as Chris did, but never saw as much power (from what I recall...). How many turbos did Phil run? He ran TWO different standalones (MS then later haltech). He ended up having to swap/rebuild his bottom end, yada yada yada. 

     

    I personally attribute many of Phil's problems he had along the way to his Maximum Boost mindset. He loved power, and instead of planning out a build, he'd turn up the boost until he hit a limitation. Fix that limitation, and then ramp it back up.

     

    Tony knows a bit of what I plan, and for my dream L build, that might actually become a reality in the not SO distant future, I'll be putting MOST of my investment into the head, then followed by the fuel system, then followed by other odds and ends. The reality is that I've seen time and time again, THOSE are the places that success comes from. Get the head to flow (which includes induction and exhaust, as a SYSTEM!), and then make sure your fuel system is up to snuff to tackle the challenge at hand. The rest is icing on the cake.

     

    I'm sorry to hear you've had issue with SDS. I also understand that it's frustrating to not be able to find someone to help you tune it. It's a rather unfortunate reality, but too many of us buy something we think we can handle ourselves, just to find out we cant', and are then stuck at the mercy of those in the know of that product. The truth is that most people should probably shop for their EMS by who they trust/know to tune it, and go with what they recommend. Many of us assume we can tune an EMS system all by ourself, or assume that a dyno shop can tune ANY EMS... Not always the case sadly...

     

     

     

    Once I had it running decent I loaded her up and took her to a local tuner that I knew didn't specialize in SDS but I wanted to give it a shot. We had her strapped down she was idling a little high 1300-1400rpm and started make the first pull. Well I couldn't get out of second gear so we went to the LCD. The LCD was freaking out showing black boxes on the display, so I whipped out the troubleshoot guide and followed the directions specific to that. Nothing we seen was out of line, started her back up (mind you we haven't touched anything) and the idle would raise slightly on its own hold the drop down 600rpm then back up. We messed with it for over an hour and the shop felt bad and only charged me the strap down fee. So I towed her home and she has been sitting since. I have a personal relationship with the guys from SDS and I have even offered to fly them in yet to no avail. I've even posted in this forum to reach out to other SDS owners local to me for help with no results. It seems like the more and more people I talk to who are either tuners or car guys say ditch the SDS and start over. Others are saying if the end goal is EFI turbo ditch the ITB.. The more this goes along the higher the price tag keeps on getting unfortunately..

    Explain to me again why you need to get rid of the ITB's to go "Full Turbo"?

     

    I'm sure George can explain what I'm talking about...

     

    I don't want the hassle of dealing with 6 ITB's over a single throttle body. Yes it can be done, yes I know the RB26 uses them stock but it was a pain to get them running decent. Besides Extrudabody only makes the back plate and I would have to have someone build the plenum to enclose them.

     

    By "Full Turbo" I mean I've had a built L28ET minus the turbo bits for years. What I thought was a progression stage and evolution of power for this engine only caused more headache. Time to $hit or get off the pot unless you have any better ideas? I'm close to washing my hands with these ITB and definitely done with SDS. I need a more modern ECU and something that someone local can tune and not rely on email and phone exchanges for minimal gain. No local car guys anymore just beyond frustrated Tony is all..

    We will NOT have a hodgepodge of wiring dangling under the dash anymore.

    We will be able to trace and troubleshoot circuits at the track without issue.

    We will not be required to be contortionists to get access to said circuits.

     

    Good deal Mike. I'm picking up a 25ft/25pin serial printer cable (different colors 16gauge around $10-$12) to re-run my SDS behind the seat and have runs for constant 12v from the starter, keyed 12v all with inline fuse and dedicated ground from a distro block.

     

    Anything outside of the cockpit will be wrapped in Raychem DR-25 Heat Shrink Tubing and Nomex fireproof braided sleeving.

     

    You might want to add an extra run to say the fuel pump just in case. I plan on doing it right for the last time.. :)

    Hell Yeah she started for the first time in a little over 3 years after taking the SU off. She started right up on the first try after triple checking everything and I even pulled the valve cover, took a plug and turned her over to build the oil pressure up and get some oil into the head. Besides from running rich and idling about 1500-1800 I have some SDS 101 learning to do. Thanks for all the support and advice everyone and watch for more videos!

    UPDATE:

     

    I am waiting on Rebello to start my damper. I had to send him the SDS Hall Sensor bracket and old NISMO pulley because he wanted mock it up on one of his motors to mount the magnets. He received it two weeks ago and said last Friday he should start this week. It's so close I can taste it!!

     

    In the meantime I picked up a BRAAP P90 to get swapped in right before the turbo goes on.. :)

    Is there anyone using this? Did you buy the trigger wheel and mount the magnets on it? Or did you drill the back and mount them the normal way?

     

    After trashing my Professional Products wannabe damper, I have been talking to Dave and Chris about purchasing one of their dampers.

     

    Thanks,
