arco, thanks for the link. Its almost a mirror image of the last few posts on this thread.

Some other factoids for this thread from my perspective. The shop manuals I mentioned are from Australia. Im probably one of very few in the US to have these manuals in english. They are specifically for the entire version 6 range. My set includes, electric, body, mechanical, and suspension. No where in the engine section is AVCS shown in the australian books. Im baffled why a version 6 sti would be made with AVCS near the tail end of the MY run. There wasnt two versions of shop manuals to buy when I acquired my books. I cant imagine a later V6 owner opening up the bay and finding that they have a bunch of mechanicals installed that arent even listed in the australian factory service manuals.

Another factoid from my point of view. My Group N car was built from a Australian V6 Donor car. It was a MY2000. I'd have to find the VIN plate for it, but it was a late production version 6. It also did not have AVCS.

For those old schoolers on the board, I spoke with Mike Shields from the old spdusa. I spoke with him about this. Same conclusion. No AVCS on GC JDM STi models. Here's the kicker though. Japan had AVCS since 1998 on 2.0 NA motors. This could confuse people in thinking it had it so early.

Folks, Im fortunate enough to have a lot of professional contact in the fields with my experience in rally. Im really not in the board to try to spread misinformation. I simply try to contribute the best I can.

Clark - If I remember correctly, you were AZscoobie? If so, I've always appreciated many of your threads. You definitely have a great knowledge of the subaru platform. With the amount of posts on nasioc, it can be easy to become frustrated with folks around here based of various comments, attitudes, etc.
I am not one of those folks to become frustrated with. Thank you for your contributions.

Regards,
Vic

I skimmed through this whole thread, and forgive me if I missed any pertinent information, but what about those of us in California?
I'm graduating from the automotive crawling in diaper stage (Honda/Acura) and look to own/drive/build a fun "real" car. Nothing too crazy just fun for a bit of spirited driving, and merging onto the freeway without having to rev to 8k to match the flow of traffic. My best friend had an 04 STi that he let me drive all the time and I fell in love! Being fairly new to Subarus I'm trying to figure out if there are any legal/BAR refable swaps for those of us here in the land of fruits and nuts. I know the engine has to be the same year as the car or newer, have all the emissions crap, can't be hybrid (correct Subaru terminology for a block with heads from a different engine?) Or are we pretty much limited to bolt ons or illegal swaps? Great info on here by the way. TIA,
Eric

Has anyone received a ref ticket with a V8 207 and gotten away without barring the swap?

Has anyone received a referee ticket with a Version 8 207 engine? Were you able to get away with making it a legal swap by having it BAR'd?

I've spoken with many people lately and they say that jdm motors cannot be BAR'd. JDM ECUs also cannot be read by the OBDII scanners.

is it better to replace my 207 block, crank and piston heads with a legacy Turbo 2.2L block, crank and piston heads or go to over on the 207 and upgrade as necessary? I'm thinking the 2.2 would be a better due to the closed deck but I'm not really in the know about these things. any help would be greatly appreciated.

Why not just put your stock ECU back in for inspection and force pass all the codes?

The EJ22t is probably more hassle then it is worth. If it was me (or when it is me) I would either stroke the 207 or do a 257 with pistons and have the CC's matched to the bigger bore. Unless you are planning on making huge power or something goes massively wrong, the case/sleeves will more than likely never be an issue.

I just picked up an ECU last night. This is my plan so far. I pray it works.

it will work, i do it once a year

remove all the tgv codes because USDM ecu will look for those sensors to be active, oh and change the injector size to whats in your jdm ecu, you want to be able to at least drive the thing in right?

fwiw, i passed my spec c ecu here in AZ, I did not have any CELs but the OBD2 readiness monitor was detected but passed anyway. I found in the ECU that it was a simple checkbox to force pass.

Thanks, who makes stroker kits for the EJ207?

I'm going to put in a stock ecu. Is anyone able to help me out with scaling my 800cc injectors, or providing a a similar map for a vf37 20g and 800cc injectors? I only need to have this on for a week assuming things go well.

if they're the same injectors, can't you just copy the flow/latency values into the other ecu's tables?

but if you want to rescale them, i read in a thread on the RomRaider forums, that to scale injectors, just use the flow tested average flow value, and then mathematically derive the latency from the stock by:

new injector flow, divided by old injector flow, (say 440cc or 565 or whatever your ecu had stock), and then multiply the your latency table by the 1.XXX value you get.

so for example, my injectors came with the flow sheet saying they were matched at 856cc. and i was working with a version 8 ecu with the stock v8 ROM in there. so, i did: [856/552] = 1.55. then i highlighted all the latency values in the latency table, typed 1.55 in the field at the top, and hit, "mul".

DISCLAIMER: i'm just getting going with tuning, so i can't verify that this is correct, or the best way to scale injectors. this is just what i used for my map, and it seems to work for me. so i'm not pretending like i'm right, i'm just trying to help by offering up what worked for me.

I was going to use the same injectors but I just threw in some 850s (coming from 816s). Can anyone help me out with scaling this weekend?

My friend who usually helps out can't find his tactrix cable. I'm in Lakewood, Cerritos, and Long Beach.

Does it come with a turbo already? Make sure it bolts up and is not twin scroll. Otherwise it should be "fine". You should get a tune for safety and performance. I don't know what you're planning on doing with other following mods so it may be better to hold off on your tune. You can throw the dp on though.

Hmm i would have to get under there to see if its a twin scroll or not. If its a twin scroll that means the DP flange wont match back?

If your car is a legitimate Version 7 2002 STi than it is not Twin Scroll and the typical Single Scroll Flanged Downpipe will work...

the oem jdm map must run extremely rich because i've seen the timing curve it runs and its outrageously aggressive. I would caution running the oem map for too long, but then again i'm a stickler for trying to remove any and all knock....my $0.02

Most I have tested are in the 11 to 1 range. Lean. There is way to much timing for US fuel. I once imported a V7 STI and it came with slight rear end damage and a full tank of JDM fuel. I ran it on the road and data logged it. It took the full timing over and over. its like 100 octane unleaded in terms of tuning. Dont run the JDM map on US fuel

wow that's interesting to note, clark. most people regard their gas as equivalent to 95 octane in US measurement. but i agree, their timing seems to ask for a lot from the gas being run. this took me a while to get my head around, even though the afr's were "rich". thanks for the post, it supports what i was suspecting. so, knock at 11:1, does that mean pre-det? or normal detonation as if it was a high afr? just curious.

If you at 11 to 1 and you see knock. Its over advanced. That JDM gas is alot better. That car took that full timing and never knocked. It also killed 04 STIs stock to stock.

hey me again, motor is in and idles fine (sounds amazing just idling) however i need a protune which i will do this summer before i can do much more (gets on and off the trailer fine and in/out of the driveway)

need a up-pipe and would like some headers does anyone with this motor have any recommendations on brand?, should i keep the EGT sensor bung so the tuner can use it? i know it will throw a CEL but this should be something the tuner can fix (if i read right)

also i am keeping the front mount (since it was fee ) im worried however about heat still since this blocks the bottom part of the radiator any input on this? an oil cooler is on the list as well but later
