I am going to buy a turbo engine and get rid of the N/A that is in my car now. When i do do the upgrade what all will need to upgraded within my car. I have an 86 rx7. If someone could list me some items that would be super. also does anyone know where would be a good place to go through to get a new engine. as far as pricing and durability goes. whenever i do get this new engine, hopefully in a few weeks i will be selling the old one so let me know if anyone wants it.

 

Sell the car and buy a turbo ii.

 

check the search button, or hit the forums on www.teamfc3s.org they have a whole writeup in the N/A section as a sticky.

 

If you read the FC FAQ at the top of the threads (https://www.rx7club.com/forum/showth...hreadid=181219) you would have found your question answered (as it is the very first question in that FAQ).

 

I was looking into this aswell, but upon further research i found out that its not worth it. You might aswell sell the car and buy a Tii or atleast get the engine rebuilt and ported(If you have already done the easy power adding mods), its cheaper than a Tii and yields good power.

 

1. Get a turboii trasmission to go with the engine or as an alternate put the N/T flywheel on the turbo engine. That's so the N/T starter will work on the engine.

2. A TURBOII boost/sensor. Twenty to thirty bucks max....used

3. A turboII ECU. Fifty bucks max...used

4. A downpipe for the turboii engine along with a presilencer or a catalytic converter. Can't use your present exaust header/pipe. Can still use your cat/back though. See MAZDATRIX.COM

5. A knock sensor along with minor wiring to it. We're talking four wires. Wiring has to go to the knock sensor on the left side of the engine to the Knock sensor. Another wire from the Knock sensor to the ECU, a ground wire for the Knock sensor and a power wire...something like that. Thirty bucks max for a used knock sensor. Cars driveable without one. But. Get one.

6. The intercooler NEEDS a air inlet. Get a turboii hood or front mount intercooler. Hood...depends..one fifty to two hundred bucks used.

7. Minor extension of what now is your split air solenoid connector to something called the twin scroll solenoid. Its just another solenoid like the ones that you presently have. Junk yard...two bucks max. Its used to control the switching actuator on the 87-88 turbo. Well worth the time to rig it up.
8. You do not need a turboII harness. That's a myth. Period. The differences b/t the wiring for a turboii and N/T are few. Like four wires, maybe five. Just make a list of the N/T wires at the ECU and compare it with a Turboii wire list and functions. You'll be surprised how few changes need to be made/ignored.

9. An aftermarket boost gauge if you really must know how much your boosting. Autometer...sixty bucks????

10. If you decide to use a turboii transmission, you'll need to buy a special driveshaft. It will have to have a turboii yoke and N/T tail piece. Mazdatrix sells them. Approx 245 bucks. They work.

11. You can live without a Turboii afm, but you should get one anyway. Up to you. Fifty bucks?? Max. File it under things to get someday.
12. Ignore any remarks about needing a check valve for the brake booster. Myth.

13. Hopefully you'll get the ducts b/t the turbo and the afm with your engine. If not....big bucks new.

14. Extend the wiring at the bac's plug so it'll reach the turboii bac on the other side of the engine. Two wires. Big deal.

15. You can run the wiring to the Port Air solenoid and Split Air solenoid whenever you darn well get around to it.

That above is talking about a series four swap.

 

unless you can get a good deal on a TII parts car, then you might as well sell your car and buy a turbo.
Basically you need the engine in long block (with everything on it), the turbo flywheel, counterweights, clutch, the transmission, driveshaft, rear end, half-shafts, and of course the ECU.
So again, you pretty much need a parts car, so you might as well buy a TII.
