AT rx8 msp turbo
 
It seems that the car is quite good, which arouses my confidence to install turbocharging. My car is AT 6port. Is it feasible to install turbocharging?

Quite the ride...show & go. Well done! :icon_tup:

Is it possible for AT to install turbocharging? What's the main need?

yes you can turbo an auto but i wouldnt suggest it. a friend turboed a 4port and it made around the same power as my n/a 6port 6spd. the auto 6port is much better than the 4port but still not ideal. members here have both turboed and supercharged both 4 and 6port autos. read the major hp threads

My goal is actually within 300p, which should be possible.

yes its possible but its more than bolting on a turbo "kit" whats your budget? what are the compression #s on your engine?

My engine compression is about 7.5, and my budget is between 70,000 and 80,000 RMB.

i have no idea what that translates to in u.s. dollars

you really need to read the turbo charging the rx8 threads on this site. its all documented many time here.

what kit?
what engine management?
cooling and fuel system upgrades?

does your budget factor in the cost of rebuilding your engine?

Zephyr, 200 gives you good advice re: boosting an AT. Also don't be enchanted by a quality example of what "can be", e.g. Fazda's ride. Hopefully you read the thread. Any reliable, quality boosted 8 will cost you resources; time, $$, "know how" & sweat. To the degree you're short on any one of these, you'll "spend" more of the others. Good luck.

zephyrsms168 02-20-2019 12:16 AM
About $12,000

Now that I've seen Fazda's case, I'm thinking about budgets and possibilities. Is AT more difficult than MT to install turbocharging?

Corresponding to the installation of turbocharging, our domestic technical engineers are more worried about the side vent of msp, and the other is about the sealing problem of O-ring. These are some of the problems I am thinking about now. In addition, if turbocharging is installed, must the engine be rebuilt first?

The $12,000 budget does not include the cost of engine rebuilding. If reconstruction is needed, increase the budget.

Does this really need it? Install RX7 top seal

Zephyr, I've not personally investigated AT installs b/c I've a MT. But don't believe its more difficult, you just won't get as much performance for the investment, which is WELL documented around here and what 200 was saying earlier.

You've interest and questions about this exciting journey, and it is a journey. That's good, but you REALLY NEED TO READ the many build threads in the Major Horsepower section, which will:
  1. inform you about our cars. ...(They dont have o-rings. They have apex, corner, & side seals.)
  2. give you insight into the challenges you're likely to encounter, and
  3. answer many of your questions re: AT platform, kits, cost, installation etc.
Issues you are calling "problems" are inherent characteristics of our cars / engines anyone boosting an 8 must understand and manage. Here are your likely choices:
  1. READ, READ, READ & learn
  2. Pay someone to do your install. (Downside is you will know very little about what w/b a fun, but finicky car, i.e. requiring supervision & attention)
  3. Spend significant $$, time, etc. ... and likely fail to achieve anything near a reliable, enjoyable boosted 8.
Choose wisely. Good luck.

Not required, but it probably reduces the chance of a big failure caused by the apex seals during a detonation event. That rotor in the above photo is still in my turbo 8 - I've had good success with it to date running around 12psi without a rebuild. But I've been luckier than most, and also very careful to avoid detonation events - I haven't noticed a single misfire under boost in the years I've had the turboon the car.

Happy to talk about it more, but it would be more polite to start your own thread rather than posting these questions on Fazda's build thread.
