You can find out the truth for yourself, same as me.

So I've been called out. Whoop-dee-do.

Let me ask you again, 9k, what's more important to you, having a bigger e-peen than me or finding out more info regarding S2 turbos?

I am all for valid data and sharing information. If you have it, provide it, if not then don't make claims you can't support about things you have no direct experience with. And yes a boosted S2 is an area I am exploring right now. And at no point will I ever need to email Dave for any information.

Man, what did Dave ever do to you?

I would've thought that a good way to explore this area would be to get in contact with everyone who has attempted this project and to see where they've succeeded and where they've failed. It's always good to get as much information as possible, right? That's why we come to these forums in the first place. I know of two people who have done it but there might be others. (Dave and the Aussies)

I'll (or the owner will) back up the claims and provide specifics of the oil lines not fitting (and the rest of the project) in due time, whether he does it himself or gives me permission to do so. All I can say right now is that the car that's currently at Speed1 had issues fitting both the oil and water lines with the Turblown kit. If anyone is going to Speed1 in the meantime, they can look to verify this and ask Dave the questions regarding this.

Well after your comments, I'll certainly be on my guard when I attempt to do this. So thanks for the warning.

I have encountered some pretty strange things when trying to tune these cars .
For example : the auto rx8 is pretty much untunable for boost via flash tuning, if you apply the same logic as the MT.

Try relocating the MAF as well for some experimentation if you have any spare time and see what results you get.

Relocate it where? Any concerns with the size of the MAF tube? Length of MAF tube? This type of detail is critical when dealing with the MAF. If you know of a general area that works for a boosted S2 then provide that info. If it is similar to the S1 then say that as well. Vague suggestions can waste peoples time and money.

I don't know of a location that works. That's why I suggested experimenting. For starters, relocating the MAF as per the Turblown Low Mount Kit and trying to get that to work is a place that I've seen people get stuck.

I didn't mean to imply that I knew of a place that worked. If I knew of someone who has a successful S2 on ME, I'd be bugging him to post his details ASAP, but unfortunately I don't.

Nothing, I just don't need to go to him for information. I am aware of that shop, I have heard good things and mediocre things from people here who have gone their. And yes sharing info is good, you have offered up no useful information what so ever.

Don't take it personal, it is what it is.

I wish you luck then in building an S2 turbo, I hope you don't waste any extra money hitting the same stumbling blocks we've already hit along the way.

What was your part in the build ?

Mainly relaying communications between the owner and the shop when they had difficulty getting in contact, delivery of some minor parts to the shop and in general, being kept abreast of the status of the car (though not as much or as in detail as the communications between the shop and owner).

I was usually at the shop for minor or non-critical fixes on a non-RX-8 or to hang out there when my buddy worked there as the dyno tuner last year. I'd be at the shop a lot more frequently than the owner so I'd update both sides with the current status.

For the actual work, none. That's why I refer any detailed, technical questions that I can't answer to Dave@Speed1.

Full disclosure: I do not currently own an 8.

Do you know if they upgraded the injectors ?

1300's I believe.

bet that was the main issue . Saw this on an auto 8 i tuned .....

How would you solve the fuel issues?

There is an issue with how the secondaries are handled in the software . The auto only has 4 injectors just like the S2 so i'm picking it's the same thing.


This took much headscratching ...... but I resolved the issue using the VE table. There will be a 'correct' way to do it but what ever table that is ..... is not labeled

I was told directly by Dave they didn't change or modify anything on the turblown low mount kit. The kit was purchased with an oil less turbo that didn't have any oil lines. He also told me it made 338rwhp @ 7 or 8 psi on pump gas, and they did about 180+dyno pulls on it. He said the only problem with the car was it would not stop throwing check engine lights, as the S2 ecu is far more complicated than he was aware. He did say don't turbo an S2.

In other words ..... you got fed a line of BS . ;)

Yeah my brothers uncles, ex sister in laws son, works there and he said that they did 338 dyno pulls and only made a 180WHP @16psi.

Yep, that would be on par with 99.9% of the rotary shops I have had experience with over the years when discussing anything RX-8 related.

Notice how I tried not to mention that it was an oiless turbo?

kthxbye.

They definitely modified the oil pan as 9krpmrx8 mentiond earlier.

Just tuned a S2 using M/E (NA)........ no problems . Very confident I could make it work on a turbo S2 as well .

All the S2 owners just got chubby

Brettus, I'm interested to see if you were to bring the car you tuned back after a period of DD usage, would your tune settings persist in the ECU or would the computer have changed it back to stock somewhat?

Why would it change? This wasn't a piggyback unit. The ECU is being rewritten. No change should occur.
