    Adapting the 240sx TB

    in Turbo / Supercharger

    Posted

    The 240sx TPS, at least all the ones I have found, are swtich type. If you get a sentra SER throttle body (like 90-92 style) its a ponetiameter(SP) type and also 60mm.

     

    The idle adjustment can be carried out by adjusting the stop on the TB so the plate stays a little more open rather than closing all the way.

     

    Also, you wont have to cut the TB shaft at all if you get the TB off of a car WITHOUT cruise control. the shaft is short enough that all you have to do is take off the linkage and the outter return spring on the TB. Leave the inner spring on there, and bolt on the Z linkage in the proper position.

    HTH :D

    SDS question, big backfire on hot starts

    in SDS

    Posted

    Doug, I have *just* installed a fuel pressure gauge and havent even had a chance to fire the car up yet. Just out of curiousity, how quick of a bleed down are we talking here? like just a few seconds after shut off, or like 5 min after? I wont be able to get around to fooling with the car untill sunday so I will repost my findings then.

     

    Drax, I found 2 plugs at the local pick n pull that look like they will work. If you want them, let me know via email Fiestaboy80@hotmail.com They came off of a trecel I think, and they werent the main fuel injector plugs, but for something else under the hood. There was no motor in the car so I really cant say what they even went to. The injectors do lock into them nicely though.

     

    Thanks for all the sugestions so far!

    SDS question, big backfire on hot starts

    in SDS

    Posted

    Hey all, I am in the process of tuning my SDS all up and I have run into a problem. When I have been hot starting it the last two days, it has let out a huge, shotgun sounding, backfire out the exhaust. no error codes, and non of the programming seems to be out of whack (ie everything is still pretty close to what SDS gave me). the START function is set at 0 for the temp range it is usually in when its hot. I have double checked the intial timing to make sure the hall sensor hadnt moved any, no difference. The car runs great otherwise and I am really happy with the SDS. If anyone has any suggestions on what I can do to make it stop back firing on hot start it would be great.

     

    My car is running 440cc supra injectors, stock turbo, 3" DP, and 3" exhaust. Just to share :D

    Running supra injectors, where to get the plugs??

    Hey all, I got my supra injectors all installed, a new fuel rail hooked up, the only thing I havent been able to find is the plugs that actually plug them in. I havent been to the local junkyard yet, so I havent seen if there is anything there that will work (no supra turbo's for sure :( ) I also tryed the dealer "you would have to buy the whole harness to get those" so that was a dead end. If anyone has info on what would work, or has a set laying around I would be greatful for the info/parts. I also hosted this picture to show what they look like. thanks all!!!

    Head bolts re-usable?

    I think I payed $60 or so when I bought them about a year ago. Should have just gone with the ARP's.... Summit has them for like $125....

     

    Thanks for all the replies, I think I will actually try to get a little extra cash together and get the ARP's before the car goes back together. later!

    440cc injectors on the way

    in Turbo / Supercharger

    Posted

    I am running the supra injectors on my Z right now. they fit in the manifold just fine, use the OE Oring's on the manifold side. I can send you some pics of the fuel rail, its a little wierd but gets the job done well. I couldnt locate the stock supra plugs, so my injectors are very "poorly" wired right now :( later

    BOV after turbo or before TB? pros/cons?

    in Turbo / Supercharger

    Posted

    The idea behind a BOV is to vent boost while you are in a high boost/closed throttle situation (ie when you are shifting) That being said the BOV should be placed post turbo and pre-throttlebody. Closer to the Throttle body is better. I have usually heard 6 inches is a good number to have. Since I assume you are running a MAF setup you will want to have the BOV "vent" back into the system after the MAF and before your turbo. the idea being you are feeding the turbo its own boost to keep it spooled for that split second you are shifting. If you vent it to the atmosphere you may experience some rich running condtions if the BOV opens any durring idle and while you are shifting.(mmm flames :D ) Hopefully this helps you out some. later!

    Turbo bolt-on for stock 76 L28?

    in Turbo / Supercharger

    Posted

    I was running a cartec kit on my car for 6 months untill I broke three pistons :D it didnt like being over boosted and under-fueled for that second. I was running a cartec rising rate FPR (4:1 ratio) with stock fuel pump, injectors and AFM. I have a feeling if you can keep an eye on the A/F mixture the pistons may stay together longer. An extra injector controller say from SDS EFI and one or two extra injectors may be able to help you out. I am suprised no one has jumped in and said how much better it is to just find a ZXT and do the swap. Good luck and happy boosting!!

    "Systems"

    I personally wouldnt do much more than 2 10's in the back of a Z. I dont think on the show circut you have to have a zillion speakers that fill up the whole entire car. I assume judges are looking for originallity and also neat-ness. IE how your wires are run, placement of amps, speakers and neon (a must now a day puke.gif ) Also if you are goin for some sort of sound qualitly other than rap/bass style music you will want to stay as far away from bandpass boxes as possible. They are "boomy" and only play well in a small band. There is a ZX on this site somewhere that has 4 15" woofers built into a wall behind the drivers/passenger seat with all the amps and shiz mounted in the back. Pretty nuts!

     

    For me, I am goin to run 1 10" behind a strut pointing twards the back, two 5 1/4 3ways in the back, two 5 1/4 component sets in the front kick panels or doors (not sure yet) with a 5 channel amp (50x4 and 200x1) I think this will be plenty of a system to deal with my musical tastes. I guess I am goin to stop rambling now twak.gif Good Luck with you system! cheers.gif
