What is the maximum octane that is available up in Washington state at most all gas stations?

Anyone seen any dyno graphs/tuning results for the JDM EJ207 with the Dom 1.5XTR?

I've found a couple that make the turbo look fairly attractive, but they've been highly modified UK Ej207's w/ cams.

Basically, im still on the stock VF30 and just stage 2 with a hybrid MBC/EBCS to prevent overboosting (was getting it a fair bit on the highway and this fixed it).

I've got Maddad headers, DW 750cc injectors and an HFS-6 waiting to go in to the car in the spring but since I'll be making a trip to the tuner anyway, I figured Id get'er all done and upgrade the turbo as well.

I gave Blouch a call and talked to someone about the 1.5XTR. They said I could expect peak boost around 4000rpm. That's basically where my VF30 tops out right now (yay for elevation!) but Im hoping to see some graphs... y'know, as proof.

As for goals... 340-360whp would be great but if I have to give up a significant amount of spool for it (too far north of 4k) then ill go a different direction.

You should be getting peak boost on the VF30 by about 3,500 RPM if there are no leaks. I had a Ver7 EJ207 that was factory from the valve covers in with stock headers and some porting on the intake mani. 20PSI at 3,500 in 4th on an EBCS.

Then I switched to a 257 and a blouch 1.5xtr and found full boost was roughly 3,400 (23psi in 4th, same EBCS, different cams) but obviously YMMV. I had the 10cm and 3" inlet, but I'd probably do the same on the 2.0. Maybe the 8cm....not sure.

Its been tested for leaks... there were none. Maybe its the elevation (~3500ft)? Maybe its our crappy 91 octane?



Zeev 91 remap 526958 by airboy123, on Flickr


Zeev 91 remap boost 526958 by airboy123, on Flickr

Tuned for 19.5psi in 4th (JDM 6-spd) on the Prodrive EBCS. The Hallman MBC was added in hybrid after and is basically only there as a clamp.

Im thinking the 8cm is the way to go for the 2.0L. I've seen a bunch of testing on the Dom 1.5xtr on the 2.5L and it looks great there... great spool.

Well, I failed NJ MVD inspection yesterday . Passed everything but the overall emissions because of JDM ecu not communicating OBD system readiness. State inspection definitely tightened up last time I got the v7 ecu to pass in the state.
Only stuff that communicated readiness were -fuel system, comprehensive component??, O2 sensors and O2 sensor heaters.

Hey, do any of you guys know if the V7 Thermostat is the same as the USDM Thermostat?

Thanks

When I did my Ver.8 swap I used an OEM USDM WRX thermostat and it is working great. I have around 3k miles on it with no overheating issues.

Appears to be same, the part number even cross references to 1990 legacys to the 07+ STi in the dealer catalogs.

Up here in Canada I lot of guys need to do use ecutek to get JDM ECUs to pass emissions. Not sure what it is they do...but it seems to be common.

I dont see how ecutek does anything to add anything to the ECU to pass emissions unless its the preferred tuning method up there to lean the car out enough for a tailpipe sniff test.
Some states here are stricter than others, AZ just looked for OBD2 connectivity and readiness, while there was a longer list of things to check by NJ. TX state inspection computer could not complete the test at all and kept dropping communication.

No...I'm talking emissions with an ODB2 connection check...

My bad: http://forums.nasioc.com/forums/show...2210698&page=6

They didn't need ecutek....but they thought it made the difference....in the end it didn't matter.

I have a question about the S202:

Does it come with the regular unequal header single scroll, or does it come with a 4 into 1 equal length header, single scroll, from the factory?

Quick question:

My version 8 when I completed the swap. I noticed a CEL, P0365 camshaft position sensor B circuit (Bank 1). I have a replacement sensor, not new, but it came from my old engine, EJ205. i was wondering if I can use this on my EJ207 motor? or do I have to buy the sensor that is made for the EJ207?

thanks,

thanks,
does the CEL go away when you get on the throttle? if so, its your avcs wiring bugging out and your sensor is fine.

Wrong forum. Since you have a built motor/hybrid motor/whatever you want to call it, I think you should go here: Built Motor Forum

I am wanting to install a front mount intercooler on my Ver 8 motor, but I am not sure of how much there is to be gained on the stock VF37 turbo. It is running 19lbs of boost on 91 oct. I am looking to get 300whp and I was either looking to go water/meth injection or a fmic and another tune. I am currently at 280whp.

Thanks

You have the stock Ver. 8 TMIC? Then there is little to gain. Unless you are going for 380whp+ the stock intercooler setup is satisfactory.

Thanks, I will just stay with the Ver. 8 TMIC then. What about the meth injection? Would I be able to hit 300whp with the meth injection on 91oct?

Thanks
