    I have seen the billet one, but they did not have the body heater hose connections. Thanks for checking.

    Status Update

    Ok, we have been so busy, I have not posted any updates.. They are in our Facebook thou.

    So, we have the rear end torque arm fixed, trans cross member done, custom driveshaft in.
    Started the junkyard engine, took some work to get the computer / wiring working, but she runs
    Built a crappy, but effective water line to the radiator. -- hope the miata radiator is large enough

    Todo list (we hope to race this weekend), that would be a 14 day swap !!!!

    - Exhaust
    - Alternator
    - Air Cleaner
    - Oil and Temp sensors (manual)
    - Fabricate firewall
    - wiring (starter, etc)

    Lots to do, about 24 hours til we load the car on the trailer, wish us luck !!!!

    Best of luck.
    Intake tube before TB: short=top end, mid length= mid to top end, long/cai= low to mid(with ok top end). Most of your power is top, so mid length should be good(about three feet if you can support it).

    Sorry guys this is a bit late: If you have some money left over you should replace the alternator pulley. The stock Eco is very heavy. Much, much more than even a five rib V6 pulley(stock GM that is). There are two makers of light weight pulleys. MRZ and MD Enforcer, MRZ's site is down right now. MD Enforcer is a member here, I have one of his pulleys on my car right now. It does help get the revs up a little faster. Not shocking, but you can tell there was a change and a nice one at that. Also it was stock size, so no need for any other pulley changes. You should stay with the stock dampner do to the rubber ring inside(takes away some vibration). Or a stock replacement if the old one is not doing the job or is cracked.


    http://www.ennotechdesigns.com/performance-pulleys.html

    Or you can PM him http://www.ecotecforum.com/forums/me...84-MD-Enforcer

    The price, well they are not cheap at 75 bucks, but for what you are doing it will help. Oh and the Twin Cam must be lighter than the Eco. Ask him(he should know), then you may be able to snag one of them at the JY if there is a good weight loss.

    Not the best way, but the fastest is to take the pulley off with an impact(on low) and put them on the same way.

    Ok, the Update !

    Head needed .12 of a grind (yah more compression), and we did the timing chain set.. It was easier as we could not find the indicators on the old chain.
    She starts and runs real good.

    Clutch barley works, the miata master cylinder is way too small, im adapting a larger one this morning
    found we nicked a brake line when cutting the firewall - fixing that too

    I did a few laps around the street late last night, feels powerful. Appeared to run out of gas when long accelerations, have the stock miata pump, may need more pressure.. (I have the pump Brett recommended), just need to match it up with the Miata Fuel Pickup

    All going well, we will be doing laps @ Willow Springs this afternoon TESTING !!!!!! YAH

    Ok, an update

    We had issues before the race with the clutch, at first it was not engaging enough to get into gear, so we spaced the throw-out bearing, then it was slipping, 3rd time was a charm and we adjusted spacers/etc..

    We got onto the track, the car felt really strong / fast.. But the oil pressure dropped after a couple of laps and the engine over heated. So I pulled off.

    We are pulling the engine and going to swap in something more reliable. I will send pic's shortly !
