I have a ZC Engine in my 90 CRX Si. It is turboed currently at 6psi. All I have right now is a FPR and a timing retarder. Next week I am getting a Crane Ignition system with an external coil. I am going to rebuild my engine to a lower compression so I take the psi up to 15ish. Here is a list of what I think I need but I am novice to turbos so please let me know what I am overlooking. Also please let me know of what companies I should look at for these products.
- Pistons
- Rods
- IC - are there any that will just fit a CRX or will it always require custom front end work?
- Injectors
- Fuel Rail
- Fuel Pump
- Programmable ECU (Thinking ZDyne)
- Block Guard (or should I get the block pinned?)
- Do I need a new Crank Shaft?
- How reliable are Manual boost controllers? Should I not bother and save for an electronic one?
- Anything Else?

Everything sounds good on what you have for plans. No, you wont need a new crankshaft unless you really want one. I havent heard anything bad or good about manual boost controls but i personally think that the electronic ones would be easier to use. What turbo are you running BTW?

it is from a 88 or 89 Mazda 626

MAZDA 626, MX6 88-92 2.2L IHI RHB52W VJ-11X

Those are the numbers for it...not too sure what they mean though :)

there is nothing easier than turning a screw:D

Sure there is....push a button or turn a knob from inside the car

Me personaly I would go with an electronic boost controller along with a Turbo timmer. Thus you can both control you amount of boost and preserve some life to the turbo !:D

cranksharft should be ok because they are already forged when out of the factory. for the ECU, i recommend getting Hondata or Haltec. i think the hondata is more affordable like ~$1000. with good tuning on the ECU, you will be able to run boost like never before. also, i HIGHLY recommend getting your fuel injectors at importparts if you haven't already gotten them. they are only $72 bucks there. it's the RC engineering brand.

for the price and function, I love my dual stage turboXS MBC

i'd be more worried about rod and bearings before a crank..... stock zc rods aren't anywhere close strong enough to hold 15pounds.

pistons: wiseco, srp, crower, arias, ect
rods: crower, je, eagle
fuel pump: walbro 255 lph
injectors: get some turbo eclipse injectors 450cc for $50 a set

i'd get the block posted (pinned) instead of a block guard.
intercooler you can use any that will mount under your bumper guard just make sure the piping is on the top or bottom.
