    1JZ-GTE Full Tune Up

    So seeing as I've started amassing parts for the winter to install on El Supro, I figured doing a full tune up wouldn't be half as bad of an idea. So this is what I've planned on doing thus far:

    Differential flush
    Tranny flush
    Obvious Oil Change + Filter
    Air Filter
    PCV
    Rad Flush
    Spark Plugs
    Maybe coil packs
    Maybe battery

    So the point to this thread, I need help in picking some parts / fluids.

    For the tranny & diff I was going to try Redline's series of products (MT-90 for the tranny and Heavy shock proof for the diff) I've normally used Royal Purple on my Skyline but I've been told that Redline offers some nice products as well.

    For oil, I've always used Castrol Edge in these babies with a K&N oil filter (just because they're easier to put on and take off =])

    For airfilters, I'm trying to keep my engine as stock as possible, so I'd like to retain the stock airbox. However, that doesn't mean I can't find a sick drop in filter.
    I've heard TRD, HKS and and K&N makes a decent filter for these. Anyone have or tried any of the above?

    NOW HERE is where i need some help. Spark Plugs... In the past, I've always gone with NGK iridiums for any car I've owned. However, a customer who brought in a R33 RB25 GTS Skyline to my shop last week complained his car did not run right after he changed his plugs. They were the NGK's and yes they were properly gapped. I replaced them with Bosch (they were on hand) platinum tipped plugs and the car ran fine. I'm just concerned about putting in *wrong* plus so to speak.

    Can you tell I'm not too experienced with the 1J's yet? lol


    So any input you guys can give me would be a big help. My suspension techniques swaybars, BiC metal end links, Cusco STB's and new shifter bushing kit have arrived, I'll be sure to keep you all posted with updates on my beast =]

    He's saying that because they burn cold. I also changed out my valve cover gaskets and my HKS BOV was alot louder.

    better seal!

    wtf???

    To the OP, you've got the fluids down pretty well, and K&N will probably be the best drop in air filter, though you'll benefit a LOT more with a complete intake system. As for the spark plugs, V-Powers are recommended. If you have the engine out, it may be beneficial as well to change the seals and timing belt if you have the money. Just good insurance.
    Our supras, who art in the driveway,
    hallowed be thy name, thy speed has come, thy will never be done,
    on the road as it is on the mind, give us this day your daily beauty,
    and forgive us our speeding, as we forgive those who drive slow,
    and lead us not into incarceration, but deliver us from the five-o ....amen

    Hmm, the only thing I'm weary about is the K&N, I've been told the oil on them isn't good for MAF's, but then again, I don't have a MAF =]. A person on Supra Mania told me I could go with iridiums as I'm not looking to make a whole lot of HP in the end result (I'm looking to make about 350 - 400 max) as it's a DD for the summer (so no mods to turbo's or fuel systems)

    V-Power is fine for that power level. As far as the Iridiums being too hot, they have different heat ranges lol. 6 is stock, start with a 7 (colder) and see how they look after about 50-100 miles.

    K&N does not ruin MAF's, they've done tests on these to prove that the filters do not pass oil into the intake tract, this is a common myth.

    I figured someone would say that. I posted a picture to try and show my set up. My bov came off of a 1JZ in Japan and came with the block off plate. It has all of the Factory connects of the Stock BOV.
