Wow, very cool. Would LOVE more info... such as how much would you charge to do this to another car, slightly less radical engine mods tho, as I need to drive my RX-8 daily.
And, can you tell us more about that georgeous red 8? What all have you done to it? Just a turbo? And what did you do about the ECU?
Thanks...

The 20b engine can be picked up for about 2500.00. Figure shipping cost, etc, you are looking about 2900, or 3000. Lets say 3000.00 for the sake of it. Now, to have a performance engine we need to tear it all down, put new housings in, new seals, etc. A typical place (pineapple, mva, etc) will charge about 6,000 - 7,000 for a ported, pinned, etc built 20B engine.
So, now you have 9,000 invested alone in the engine. But wait, you cannot just plop the engine in the car and go. Lets add some other things. Turbo. 4k is a good estimate. A typical Innovative dual ball bearing turbo runs about 2200.00 from them. Add the custom manifold, 1000.00 (conservative quote here), and a large wastegate to support the airflow, figure about 600.00. This right here adds up to 3800 not including shipping and other little nick-nacks (nipples, wastegate spring, etc, etc).
So, thus far we have 9,000 for an engine, and 4,000 for the turbo. Thus, 13,000 invested so far.
Well, lets talk about an intercooler and radiator setup. Due to the heat and cooling charge, a typical 20B custom intercooler runs about 1700 - 2800 in this industry. You could get away with an off the shelf unit, but that sacrifices other areas. For cheapness sake lets assume the intercooler was 1700.00 Figure piping now. Custom 3" piping and silicone tubing would run you about 300.00 when said and done. That is about 2,000 for the intercooler setup right here. A good radiator and fans will run about 700.00 total. Now, because you have a 20B you have to change the water pump housing design area too. This will cost about 300.00 extra. So the cooling area is now 1000.00. Total, we are talking an aditional 3,000.
To add what we have thus far, 9K + 4K + 3K = 16,000.
Ok. Yay. We are getting close. Lets talk about the ignition and computer system. We have to have one of these to run the car correctly. Lets talk about the computer system first. There are a few choices to choose from. A microtech, Haltech, and a few other more expensive choices. For sake of this particular conversion, lets go with the microtech. Once you add up all the computer stuff (LTX12, 3Bar, Wiring Harness, Wideband Sensor, Laptop Port, etc), you are at about 1700.00 or so. Also, you need coils to ignite the plugs. You will spend about 600 or so on just the coils, and an additional 120 on good wires and plugs. How are we doing thus far? 1700 + 600 + 120 = 2420 for the computer associated stuff.
16,000 + 2420 = 18420.00.
Now, lets talk fuel. We are not going to use the crappy stock injectors, lines, and pumps. We are doing it right remember. Add up all the large injectors, fuel rail, two fuel pumps, sump, and lines. You are looking about 2300 or so for all of this. Keep adding.
18420 + 2300 = 20720.
Now, lets get to the drive line issue. These stock axles cannot handle this torque and hp. Instantly, we are looking at 800 for new chromoly axles. What about the diff? Nope. Crap with this power. Add another 800.00. Ok.. Transmission? Wait... we will be using a Guru 6 speed dog box. Oh, that runs in the neighborhood of 8,000 more. What about a 20b flywheel and counter weight? Oh, lets throw in there for 650.00. Clutch? Yep, need a strong one for the job. This will cost you about another 500 for a good unit. Lets add up: 800 + 800 + 8000 + 650 + 500 = 10750.
Add it to our listing.
20720+10750 = 31470.
Ok. Not done yet! What about the gauges? All the Defi system is needed. Boost, Water tempature, fuel pressure, egt. Dont forget the pods. This will cost you about 950 total when all said and done.
31470 + 950 = 32420
Exhaust! Oh we forgot that. 4" exhaust with muffler, and setup stuff. That will be about 1100 total for the downpipe (custom made) through the back of the muffler.
32420 + 1100 = 33520.
Ok. Misc parts must be needed. All of this is what kills you. You can budget about 5000.00 for this. This would include all the little stuff. Shortening the LIM, and UIM, various little things that you need, hoses, etc etc etc. Ask any one who has done a 20B conversion, and they will tell you this kills you here. For a shop, the cost would be less. Lets average 2500.
33520 + 2500 = 36020
Now, what about labor, dyno tuning, etc?
I think I will stop here.

He does go on later (on another thread here, but total cost is over $80k - all this is rough guesswork and I dont think includes peoples time/work.

but still, a really good motor can be built, tuned, and installed for less than $40k.

The 40K is just not motor. is every thing around the motor, plus labor, plus pick and delivery, ECu, tunning, dyno, MSD, etc etc. go to my website, and it shows you a complete list
