Starting my turbo project. Please Help!
Hi folks, I have been reading threads here for a while as my turbo plans progressed from ideas parts in boxes. I think its time to introduce myself and ask my questions.
OK, this is what I have so far.
One 94 miata with totaly stock engine.
One remanufactured journal bearing t25 turbo from a FWD nissan sr20det.
Compressor: 54.36mm exducer, 60 trim, .80A/R housing.
Turbine: 53.0mm inducer, 62 trim, .64 A/R housing.
One used JR AFPR/FMU, I don't know the rate of rise but plan to test it.
One new BEGi new style exhaust manifold, and one new BEGi series Z mild steel downpipe without the sparate wastegate path.
One used emanage blue from mohdparts, tested and updated with the latest firmware by them, complete with main and ignition harnesses and injector wires.
One nokia dku cable on order, my old (win 95) laptop has a usb port, but I don't know what drivers I might need, Im sure I have a normal USB cable lying around someplace.
One used Subaru WRX stock intercooler, size is just right, and dirt cheep, but plumbing will be a pita.
Cheep ebay foam air filter, I oiled it.
OK, now for the hard part, what I still need.
Coolant lines should be fairly easy I like those bajo fittings designed for "pushlock" hose that atp has.
I keep wondering if I can just push a barbed adapter into the other end of the pushlock hose, or if I need to do pushlock to npt then npt to barb to get to my normal coolant hose?
Fuel lines are the stock springy hose clamps up to the task with the FMU or do I need real ones? Some of those clamps are real hard to get at.
To clock the turbo, I have the big *** snap ring plyers, but I still have to do something with the wastegate actuator. I think I can just drill and tap the outer ring of the innside edge of the turbo's intake housing to mount it in any orientation I want. Correct?
Oil suply line. I have a block to AN fitting from BEGi, but I still need the line, anyone know how long to have it made and what angle fittings work well? Does my turbo need an oil flow restrictor?
MAP sensor. Do I need one? doesn't the MAF provide a good load signal? Is it needed if I go for the autotune?
Speeking of the MAF, I still don't understand the emanage manual, do I need to use a resistor or not?
To take my LC-1 out of the MR2 and put it in the miata along with a display and a boost gauge.
Oil return. Easy.
Thats all I can think of right now, I will try to post some pictures of parts tomorrow. What do you think?
