    L28et help me choose Comp. Ratio, camshaft and Turbo for best synergy

    in Turbo / Supercharger

    Posted

    Ok so I'm gonna keep my flattops and keep my bottom end stock.

     

    Gonna put a unshaved p90 on my F54 w flattops should be around 8.3cr.

     

    Battling pre detonation w a stock sized Headgasket to utilize the flattops quench.

    A wide band o2

    Megasquirt 3 for fuel and spark

    A ported free flowing head

     

    I need to find a turbo that can boost efficiently and not raise temps.

    I want the t3/t4 everyone talks about.

     

    How do I find out what size parts to use in it to match my custom "a" grind cams powerband.

     

    What trim? How do I find out exactly what turbo to have arizona z car build?

    Gotcha gotcha. Well I've got an NA cam to grind. It costs only 170 to do it.

     

    With that and ported head with ported intake runners do you think I would be gaining closer to 500??

     

    I guess I'd rather have more power and be able to turn it down for reliability.

     

    Then turn it up for drag or something.

     

    I'm allready beefing up the axles and stuff for high power.

     

    Is head work a waste of money too for 400 hp??

     

     

    I guess I'm at this cross road

     

    Do I get head work done and pop my p90 head onto my stock NA bottom end with the flattop pistons and call it a day

     

    Or

     

    Do I replace the pistons and install arp hardware along with it

     

     

     

     

    Or not do any headwork, pop the stock p90 head on and leave the bottom end alone?

    I basically need to choose a

     

    Piston set and comp. Ratio

    Camshaft

    Flywheel weight

    And Turbo

    for the best synergy.

     

    Doing my first high performance engine build

     

    I can't decide holset hx35/hy35 or arizona z car t3/t4oe 60. Trim

    I like the idea of water cooled turbo btw is that necessary?

     

    I want to build the turbos boost pattern to match the powerband of the cam.

     

    I want to get a custom cam grinded from a NA cam by "elgin cams" and I have a list to send him of my turbo specs, piston compression ratio and head cfm's etc.

     

    He grabs all that info and makes a perfect cam to synchronize everything.

     

     

    Pleaaase DATSUN GODS

    I need HELP and ADVICE other then the research I've done filling out the list for my engine build!!!

     

    Shooting for 350-400hp for drift/track car i can mash on reliably all day.

     

     

     

    I have MS3 and a innovate o2 sensor

    P90 head that will have a mild bore

    Bored out presmog intake/exhaust

    Isuzu large npr intercooler

    Big fuel pump and fuel rail and 450cc injectors

     

     

    I need help choosing a set of pistons and their CR. Want forged ones

    Can't decide super low comp. or high comp. for more low end torque

    I want to keep my 3.9 final drive

     

    I need help deciding what flywheel to use if I should go light or not

    If I go high compression I'll go light I guess?? If low compression keep it heavy to balance torque/hp ratio?

    need BOV, L28et, p90, t3/t4,oil/coolant feed,engine/tranny mounts,shifter bushings,ms3,gauges,

    Finally getting parts together for a textbook hybridz turbo build!

    Got a email back from diy. Looks like everything I want.

    Hello,

    Here’s a quote for a pretty complete system with the ECU/Stim assembled: 

    CLTIATwPiggy- $17.75 GM CLT sensor

    MS2357-C $445 Assembled Megasquirt-II with V3.57 PCB

     

    MSHarness $67 8' wiring harness

    IATwPiggy $22.25 Intake Air Temperature Sensor

    38NPT-Bung_A $9 Aluminum bung for IAT sensor (Also available in stainless steel)

    TuneCable $5.50 6' DB9 tuning cable

    USB-2920 $22.50 (Only needed if your laptop doesn’t have a true DB9 port)

    MSRelay-C $94

    TW_L28ET- $28

    Subtotal without wideband-- $711

     

    The Stim kit is a good idea if you are assembling your own ECU so that you can check the ECU while you build it. Also the standard MAP sensor reads up to 21psi, above that you can swap to a 4 bar map sensor to read up to 44psi. Yes the ECU will read a variable TPS from a 240sx.

    Okay finally comming across some money and I'm getting all my parts lined up.

     

    I'm a over the road truck driver and I'm working on my car on the road and once every 6 weeks while I come home.

     

    I'm going to be porting my non egr manifold next week and am creatively thinking of ways to work on bits and pieces while I'm on the road.

     

     

     

     

    so far I have...

     

    440cc supra injectors

    Non egr intake manifold

     

    Free ebay boost controller w gauge(guy that I bought the injectors from said he bought a different one because he couldn't read how much boost it was giving,not sure if I trust it I'm trying to hit 18psi)

     

    Walbro 255 fuel pump

    Rx7 fc oil cooler

     

    steel mandrel u-bends for intercooler piping that's left over from exhaust work

     

    Aeromotive a1000 -6an FPR w gauge

    89 240sx throttle body w/ TPS from manual transmission

     

    -Need to get a whole megasquirt package.

    Thinking ms2v3 w relay board and whatever makes it easier to install. Still doing research.need help installing this at least some supervision.

    -Need turbo engine w everything attached

    Manifold,oil line,harness,dist,

    -Need t3/t4 turbo (don't know what type?)

    -Need intercooler (large npr)

    -Need wide band O2 (?)

    -Need BOV (going cheap 1rst gen dsm)

    -Need radiator fan (taurus fan mod)

    -Need plans for ignition (msd 6a?-stock?)

    -Need pallnet fuel rail and TB spacer

    -Need nissan injector seals for supra inj.

    -Need manual steering rack so I can add steering angle

    -Need 2.5 downpipe

    -Need help installing all this crap haha

    -Need help filling in the blanks for my parts list

     

    Plans during the build

    Look for rust under battery tray

    Paint engine bay

    Wire tuck and vacuum line tuck

    Delete egr

    Maybe move charcoal canister or remove

    Need to learn how to run coolant line into turbo

    Want to wrap EVERYTHING with heat wrap

    Want to do any other cooling efficient mods

    Need to figure whether I'm keeping AC or not

    Need to figure if I'm going to a manual steering rack or not "goal is for better steering angle for drifting""also will take stress off pulleys and allow for a lighter pulley"

     

    Goal is as close to 400hp as I can

    I'm going non sequential with Megasquirt if I can get away with it.

     

    Need to know if I will really benefit from Port polishing a p90 head even though the cost is about 2k."money is kind of an issue but I can value time and money spent early instead of redoing it all"

    battery relocation

    Buy a deka battery. It's the battery braille uses. They then wrap carbon fiber around it and mark the price way up. You can buy two and use them for daily driving then on track days take one out. And the one I have in my lil motorcycle has enough cca's to turn over a dodge viper.

    bought pacesetter headers, will my car smog now?

    in S130 Series - 280ZX

    Installed the pacesetter headers yesterday, my neighbor helped me. the egr tube was not long enough and it had to be cut and made a loop extension pipe and used jb weld and some heat wrap to mend it.

     

    also there were 8 mini circular shims that had to have a 1/8th inch grinded off them to be flat so the intake and exhaust manifold would fit flat. it came with a gasket and i bought a felcro gasket and some copper heat spray for the gasket. 2 studs were broken and were a pita to get out, but they came out!
