Thanks I'm looking forward to it!

Good luck with your GReddy turbo!!

 

Subscribing...
Simply,
I would listen to Mysql about the fuel pump and the ignition. For the ignition, there is a better preformer ( cough BHR, cough) for less cost, that dosen't require a diffrent tune that adjusts the dwell of the ignition coils.

The Mazsport coils have diffrent dwell than the stock coils that does not play very well with FI'd applications.
Now since you have the AP, and if MM (assuming you purchased it from him) is NOT Aware of the Ignition coils you are using, when he sends the FI'd maps to you, you WILL have problems.

Also invest the money into the BHR AT Radiator, and a second oil cooler.
My first oil cooler bypass valve falied shut, but thats another thread.

The AT will put down more Tq at the same psi than a MT using the same turbo.

 

Regarding the BHR radiator & a second oil cooler, I've already got those down, the list on the front page is kind of incomplete now since I've added a few more things. Updating the first post now.

Regarding the Mazsport upgraded fuel pump and ignition, it appears that yes some people have had problems with both, but many people haven't had issues. I will keep it in the back of my mind though, and talk more to Ray and Erick about it when they get here.

 

Good news everyone, I just bought a greddy turbo last night, so i will get it about 2 weeks hehe I can't wait.

 

Are you getting Jeff's turbo upgrade?

 

you will have 600whp if you just get a electricsupernawzcharger

 

lmao

 

who is jeff??? I had my local shop ordered for me, because he can get for a cheaper price.

 

MazdaManiac

 

Good planning there.

 

Jeff = Mazda Maniac the turbo king

Did you check with BHR for a turbo price? Oh well if I had your money I would not shop ether.

Can't go wrong with a BHR radiator for any FI application.

 

That's what Ray told me, and told me, and told me, until I finally bought it









Just kidding, he only recommended it once And boy, I can't wait to get it!!

 

UPDATE
I spoke with Scott @ Mazsport yesterday and he told me (Scott - correct me if I misquote, I should have wrote this down when it was still in my mind yesterday) I will get ~270whp @ 14 psi. He said that due to the fact that it is a 4 port automatic, I already have a lot less power to work with. He said that most of the turbo kits he's sold to automatic owners have gone to Europe, and he hasn't received or done any dynos on AT RX-8s with his turbo kit.

Assuming my AT RX-8 gets 140whp right now, that's almost double the hp to the wheels. From his sig, 09Factor is getting "185 HP and 242 Tq @ 2800 RPM @ 5 psi" with the GReddy turbo, I know you can't compare turbo to turbo hp for hp, but if you could that would be 353ft-lb torque.

One other thing to note, the 270whp is at 14psi, I doubt I am so daring. I will probably never venture above 8psi, and in fact I'll probably be content at 6psi. Even with Water Injection using the AEM meth kit, I just don't think it's worth the risk of trying to run my car at 14psi.

At this point I just want the temps to stay low, fluids to flow, and my AT to go go go!!

What's funny is the that some MT can get over 400whp with turbo and us AT, despite all that we may do, will likely never get to 300whp. I'll try to do a dyno after everything is installed and tuned - that's the only way I'll know for sure.

 

Don't foget young grasshopper that the Greedys 5psi flows diffrently than that of the Turbo Mazsport is using @ 5psi..

Presure is just that, Pressure. It boils down to Lb of air flow of the turbo.

 

Ya I know, I said if you could compare them directly and the math were exact

It's wishful thinking!

 

So this is going to be fun. When ever your ready simplyphp! Get the BBQ warmed up!!!

 

That is only the 4 port AT, the 6 port AT will (or should) be capable of the same HP.

 

So it's a give or take in terms of how long it will last, the 4 port will last longer because we can't abuse it as much as we can abuse the 6 port.

 

Now I hope I did not give that impression. I honestly wish that the 4 port AT trans was compatible with the 6 port engine. For me that would be the best of both worlds, the better AT trans and the engine with more power and power potential. As far as abuse, they both are susceptible to misuse, over heating and inadequate oiling. While I feel the 4 port AT trans will handle 300hp, I would not feel comfortable with it trying to handle more. We'll have to wait until someone with a 6 AT gets his up to 400hp and see how the 6 AT trans will perform.

 

Seems like you'd have to be running an absurd amount of pressure even in a 6 port AT to get to 400hp, seeing as how the 6 MT are barely at 400 and that's only one or two people. There's not really much else I can do to the car beyond an engine swap that would get me more power out of my 4 port... except raise that psi. And the 6 port AT has what, 15hp more than the 4 port? And the 6 port MT has 35hp more? Maybe I'm doing my math wrong but that doesn't put the 6 port AT at par with the MT, it puts it at ~325-330whp - IF the 4 port can get 300whp.

But then again, I don't know about the 6 port getting the same gains as the 4 port, because the 6 port already has more cc's of fuel going into the engine, and I'm upgrading the fuel injectors. Since the 6 port already puts more cc's of fuel in that the 4, upgrading to the amount that the 4 upgrades to puts them now equal... Then using the same turbo, all other components the same except the fact that it's a 6 port & has the 6 speed tranny. I doubt the gap would by 30hp, and I seriously doubt the gap would be 100hp.

But I don't know for sure because I'm not a pro by any stretch or even a mechanic by any definition. I'm just going off of figures others have presented and some basic logics, though logic is sometimes flawed.

And speculation doesn't count for anything - the only way we will know for sure is when a 4AT dynos @ 300whp and a 6AT with same mods - or hell any mods - dynos @ or + 300whp.

Everyone seems afraid to turbo their AT, coupled with the fact that EVERY TIME someone asks a "how can I get more power out of my AT" their question is answered with "n00b trade in y0R sux0r autotrajicz and get a MANUAL!!" It'd just be nice for us AT, regardless if we're 4AT or 6AT, to post some respectable HP #s, and I think 300whp would show all the MT owners that the AT are still fast and worthwhile - you can have your pie and eat it too.

 

That comment is usually mabe by those are narrow minded in believing that an autotrajicz has no place being in a "sports car". Also it come from a group that dosen't know what TorqueFlyte (sp?) tranny is.

The 6port motor has 2100 cc of fuel delievery, the 4 port has 1570.
Upgrade the 4port inj's to equal 2100 cc's of fuel the power output will be close to a turbo'd 6port.

But then the VE's of the motor rear their ugly heads and start messing with the power that can be produced from the motor.

 

Well put, the limit of the 4 port eventually is reached. The theoretical limit is very nice as most of us 4 port AT owners are looking for the 300hp range.

 

Maybe I should. I can't be any worse than whats in the running

 

09 Factor for highway commissioner

 

You guys are hilarious :-) I don't know who is more excited at this point, Phil or myself.

Phil because Ray is rebuilding his engine, and he'll have his kick *** s/c ride back
Or me because Ray/Erick are going to come "throw sum D's on that b!tch" sittin in my garage :D :D :D
