    NON-Z (Engine choices: Info Needed)

    in Non Tech Board

    Posted

    Out of those two engines, definetly go with a KA24DE. Its a great engine. Strong, and reliable. idk anything about the other engine. but the KA, in N/A form will make upwards of 220-240rhwp on motor w/o juice. With a turbo, you can manage 350rhwp on stock block, so anywhere from 10-12psi, maybe even 14psi on a T3/T4. The only problem with the KA is the weak ringland. They will blow after 1bar (14-15psi). If you run forged pistons ( many choices, Supertech, Weisco, Ross,) Forged Rods ( Aries handle up to 700rhwp), you should be able to make around 500-600rhwp with 25-30psi on a big turbo. You can run a T66 a SC61 a T3/T4Oe. The head, stock flows pretty well. On N/A cams you can make decent power, If your cheap, swap in a altima's intake cam so you'll get 248/248. Anyways, if your going with a 4 cyl, definetly go with a KA24. If your going for a high revving car, get a 3rotor, 13B, plenty fast with a turbo. Also, dont get a S2000 motor because it would take a shitload of money to make it fast, if you put I/H/E you could actually lose power on it.

    Treating Metal

    in Body Kits & Paint

    I cut out my rear end, and welded everything back together, but because of the moisture, there's surface rust on the new sheet metal, what should i paint it with or prime that wont rust it out again. Or is the sheet metal bad. I looked at POR-15, also searched. Thanks

     

    EDIT: A more indept search, i found out about RustMort. If any has any more ideas about this please post.

    compression: http://e30m3performance.com/myths/more_myths1/comp_ratio/comp_ratio.htm

     

    A AEM AMS costs about 1700 for a KA(idk about the L28) and should be around no more than 500 to install. I recommend a standalone if you're serious, but you can try a piggyback, like a Emanage, or a Megasquirt.

     

    I believe Arizona Z sells cams, and they can regrind to any spec you want. For the cam it depends on what you want, like if the car is going to be streetable, you need a mild cam, so not to crazy on the lift/duration, so your idle isnt like 2K, most cams will eliminate low end torque, so for streetablility, idk if you want a large cam. What is the car going to be used for ? daily driving, auto x, etc ?

    Rebuilding my L28E

    I'm rebuilding my L28E to hopefully run 12's. I got a turbo motor which I will be using parts from since I want to save the 60,000 miles on the block and head. I'm going to put a L28D crank in it but I want to keep a low compression between 8-9 :1. How should I set up the pistons and rods?

    The pistons, depends on your bore, can be .20 / .40 overbore, and must be forged, the rods, aswell must be forged. So if you're going all motor, you must bump the compression to atleast a 10:1, but for a turbo that seems fine.

     

    Next I will be having a custom Intake and Exhaust manifold fabricated. Should I get the intake and exhaust holes bored? If so how much are the able to be bored? And how does $2000 sound for the both of those together?

    I was quoted 1300 for a twin turbo header, so that seems reasonable. What do you mean bored ? Do you mean port matched, if so then yeah.

     

    Then I will have them install a universal intercooler (which I want to be very efficient) and fabricate the piping. Any ideas on what I should look for?

    Read this : http://www.are.com.au/techtalk/intecoolersMR.htm#ENGINE%20DESTRUCTION%20%20!%20!%20!%20!

     

    Then they will be installing an ECU for me which will run about $3000 installed. They are going to re wire everything. Then it will be $150/hour to tune it.

    What kind of ECU, that seems way to much, unless you'll be running a standalone like a AEM AMS, or TEC3 but still thats alot.

     

    I'm going to get an angle job on my P90 head. I've never sent a head to get machined, so can someone fill me in on how this works and what I should ask for?

    Read this:http://www.sa-motorsports.com/diyport.shtm

     

    As for the turbo I was going to use a GT40 turbocharger from Arizonazcar.com but they got two different A/R. Which one should I use?

    I will be running this turbo as well. Read this:http://www.forcedinductions.com/help.htm

     

    Then I will run a 3" exhaust from the turbo with a test pipe in case of emissions. I want to go no muffler but I'm a little weary about emissions. How should I set this up?

    To pass, you will need to run a cat and maybe even C116.

     

    In the end I hope to obtain a 3.1L turbocharged reliable engine for my 280ZX. I'm going to hook this up to a 5-speed from my '79 and then to a 3.90 differential. If you guys take the time to read this, thanks and leave any advice or comments about what I'm doing

    B) You can either get a custom manifold with the correct flange made or you can have the stock manifold modified to take a new flange. Both will run in the $1000 to $1500 range if you don't have the facilities to do it yourself.

     

    c) Uhhh... I wouldn't count on it. The stock 'automatic'? transmission will have a significantly reduced life expectancy somewhere after about 200 crank horse power.

     

    I would look for a 5-speed' date=' drive shaft and probably an R200 from a donor 280ZX.[/quote']

     

    wow, thank you for the links , also if my ZX has a auto does it have a R180 or a R200 diff ? because i heard that all the ZX's have the R200

    Turbo on a L28E?

    in Nissan L6 Forum

    Posted

    I bought a 83ZX, i was planning on putting in a KA24DET ( i have a FWD KAT) but now i feel that a L28ET will be enough. My question is a) where can i get rebuild parts from ? Is Arizona Z the only place ? B) What do i need to run a GT40 or a T66 maybe even a SC61 on my L28. I know i need injectors, fuel pump, etc. Is the OEM turbo header the only option next to a custom header ? I searched and found that no one has exhuast manifolds for the Z :( Also how well will the stock auto handle 350-450rwhp.
