I wanted v7 for the pistons, but I also didnt want a motor that has been sitting alot longer. I opted for the v9 because it's newer, twin scroll, heads and condition.

I did. Let me know if/when you get a tactrix cable, let's see what kind of ROM you have. You can use that cable for logging anyway.

-ECu
-Immobilizer ECU
-Key with transponder
-The antenna is in the light ring arround the key. It may be separated from the ignition key cylinder.
These have to be all matching, the swap vendor would have to provide them.

Then, the USDM has an immobilizer pass-through, through the gauge cluster. This meas that the cluster does not hold any immobilizer components but has a blinking light and such.
In the wrinkleboi thread, one guy skipped the cluster and was able to get the combo to work just fine.

You tape the key to the antenna under the dash, this way you never have to go to the dealer to ask for a spare transponder key for a Japanese model, which they are not likely to ever get done.

http://forums.nasioc.com/forums/show...ht=immobilizer

I do have a connectivity diagram for the immobilizer, that I could post, but it's in Japanese ...
One thing which I was reading is that they flop the pins for the fuel pump controller at the ECU so that you cannot start an immobilizer car with an older ECU.

Of course, you could run the V9 with a reflashed earlier ECU.
Here's a link to a thread where the forum member runs an S204 (which is a V9)with a V7 ECU.
http://forums.nasioc.com/forums/show...2230372&page=2


So basically it's time to move to the V9, guys .

Yup! Thanks for all the help throughout the day.

After I finally got home from work I spent a few hours researching here on nasioc and the www. I figured out that stuff and some other stuff.

I spoke with my jdm vendor. They only had the immobilizer and ecu so I decided to go with the V9 and V8 ecu. Plug n play with the IAP kit (which I will be ordering tomorrow)

Negative, I still will be. No problem not to. Clark even said he's tuned many v7-v9 with 30Rs, even some 35s.

Vlad, Do you know if the V9 Spec C cams are the same as the V9?

if you were good and depending on what flange the turbo has, you could possibly get a twin scroll exh side in t3/4 and then bring each of the v8 up pipes to each inlet on the flange. weld the inside then a cover piece on each outside part and it would tech be twin scroll t3/4 flange. should help down low! i am currently in the process of trying out a new style quickspool valve we prototyped and machine up in the next week. should help the big basketball turbo my friend has spool before 4500rpms.

sure, you can do almost anything with custom fabrication, you can even run the uppipe to your trunk to run your turbo rear mount mustang style if you want

I think moore posted recently about making some custom uppipes in the stock location twinscroll thread.

Talking about other communities, the 3000gt guys moved (after garrett ballbearing cartridges and after machined compressor wheels) to medium sized Titanium Aluminide turbine and shaft.
According to a coworker, apparently they can spin wheels by flooring from cruising rpm's.

We have them in the Borg Warners, but that's a big turbine-shaft unit and that denies the weight savings, I think.
There are the VF42, but too rare and too expensive, probably not long lasting either and I don't think they can touch 300whp on pump gas.

i've only seen the supra guys run them, and i doubt many do because they can sit on the line to build up boost when they want to spool for 1/4 mi or Texas mile type events on their big turbos. That is if you are talking about that valve Sound Performance has to sit inbetween the exhaust manifold(uppipe) and turbo hotside inlet.
Since they are actuated off of boost pressure, i'm skeptical if it would be practical rather than just getting a smaller hotside for your application. If you do try it out, share the results!

its mainly for building boost faster. yes the valve placed between the up pipe and turbo hot side. it should help accelerate the air into the single scroll. we are going to try it to see the difference with it always closed to when it will open prob around 15psi. my friend is going for 450whp on pump and prob pushing it to 600whp on 113 octane leaded fuel. if its too big he is going to downsize to a borg warner 200 series so its more street friendly.

I was running an idea through my mind this morning. I have two bugeyes. A Black one with an 03 wrx harness and ecu, the other, white, with an 05 sti harness and ecu. Could I swap the jdm v9 engine in the white one, install in the jdm v8 ecu and be ok or would the usdm immobilizer issue come up?

Have an of you guys bought or are you familiar with the downpipe option from Tomioka Racing? Sold through EDO Performance.

It is supposed to be twinscroll flanged and usdm length.
However someone on the boards here says that is is not usdm length and not 3" as advertised.

Are any of you guys familiar with this pipe?
I'm looking for a TS downpipe that is plug and play.

Can I ask, what's the sense of a twinscroll downpipe? It's all going out one pipe throught the exhaust.

If you have a twinscroll turbo you need a twinscroll dp as the flange is different.

Does anyone have a v7 spec C or v8 ECU they want to sell. Heres the catch, it CANT have the ECUTEK software on it. The JDM ECU I have currently in my car has ECUTEK and as such, its locked. I can't get it tuned open source unless it's through ECUTEK. I plan to do some mods in a few months, and would like an ECU that I can tune with without any problems. Thanks!
