Rotary Extrem
 

Hi everyone I got a good news, I just talk to Ben in rotary extreme and he is going to help me install turbo for me and tune it for me. He will help me bring the most potential out of my 4-port AT. We are planning bring out the most HP and yet safe for daily driving. I am really excite that Ben is so nice and willing to help me the best he can.

what turbo?

greddy, but he suggest that i should buy from MM with the greddy upgrade kit. which most likely what i am going to do.

thats my plan, but i'm going to use the stock greddy turbo first.

sooo much tuning.. sooo little time

to him its a really easy job

How much would the total cost be? And also are you going to get a BOV for an auto? i wonder how that works. Only hear it in tiptronic mode? Im planning on supercharging or turboing but i dont know the price range with tune and labor and all

Really? A Blow-off valve works by pressure differentials, not transmissions

:lol:

i gonna take me car to paul at rotorsport. ^_^ i'll give em a call tomorrow at rotary extreme.

anyone found out about the pricing? How much labor is etc?

well I have to provide all the parts and things like that, since there is no shop anymore because Chuck went back to Taiwan to do personal things. But Ben outrageously charge me only $400 for labor plus shop rental because he is really nice and really cool with me. There is no shop i know charge that price, anywhere is around 800-1000. but the parts including the turbo you are looking about roughly 5500 dollar, Turbo, gauges, pods, boost controller. engine gasket. did I miss anything else?

Thanks for the info! now i know where i am looking into when i decide to go fi. I always wanted to know how much labor fee would be etc. Not too bad ay? :)

you also have to buy Cobb from MM, Yeah when you have all the parts and ready to install. Then you can talk to Ben for it. even though he charge fof cheap price but when I get all m parts, I will pay more then the price he offer just because he is cool and he know the stuff. I rather pay more to the people who know things and I would say Ben are one of the best in the Bay:eyetwitch

what is his phone number laulongfei? pm me plzzzz

I'm going to throw this wrench into the mix.
For us 4 port owners AT/MT The 3071r that MM supplys dosent reach it peak efficency until after 7500 rpm. :banghead:

Just a thought.


However I agree it's a much better turbo than the Mitsu snail that the Greddy kit uses. The greddy kit was built on a 4 port motor btw.:icon_no2:

No it dosen't. It only works on M/Ts and you know that.;)

Are you saying that Mitsu snail haha, give more torque than 3071R under 7500 rpm? Is it because its a bigger turbine? what makes you think that? What I really want is Torque on lower rpm. I think it produce peak torque around 5000rpm.
I dont really care about high rpm. since our trans aren't made for that high speed turning. But it can hold above 300BHP(RE-Amemyia said it.) But the problem he said is that You have to manually shift if you are running high HP and each time you shift, let go the gas pedal and wait couple second before shift to next gear or down gear, so that the band will not slip.

what is 300bhp=???hp, none of us have reach that high, so I will be the first lab rat. hehe But another concern is that 4 speed will reach high rpm so fast since its not 6speed. if my tran broke during the test(knock on wood), i just sent it to Level 10 and have them beef it up.

I'm not saying that at all. The peak efficiency of the Greddy turbo is under the mazda imposed rev limit of 7500 to 8k rpm. It craps out around this range.

The Garrett 3071r's efficiency is at the nearer to the 9k rpm range.
look at the following post by MM.

if anything the Garrett will make more tq at any given boost psi because it flows more air per psi.

All i was trying to point out is that the Garrett doesn't get used to it full potential on our 4 ports at the 7500 rpm limit.

Amemyia-san is wise young padawan. :)

Cool, thx 09 factor, that is another very educational lesson.
Did the turbo makes a big difference from NA to 5psi turbo, interns response of the power and overall performance.
I want to get an idea how my will feel when my get my turbo install.

It did make a differance, but it's more "feelable" @ 9psi.

Damn, I've been living in a cave my whole life!!
