The section of table that you posted adds model numbers for rev F and G and correct E model numbers.
In many cases, what people are looking for in a table, is engine code number, ECU code number and part numbers for those and maybe internals part numbers. The articles are a collection of articles mostly from British media, I've read them before. Where it gets confusing is that at least two of them do not actually refer to a stock Spec C, but to a Spec C that has been modded by Litchfield. Litchfield is not only a tuner, but also an importer into the UK. So It's confusing, when you look at a "Litchfield special" to see whether it's output is what the car had when it was stock in Japan, or what Litchfield tuned it for. In this case, they added an exhaust and tuned for UK gas. Also, the units can be allover the place in different articles, in some you have BHP, in some you have PS. |

The S202, 204, 204 and Ra-R had the expensive inlet.
Right now however, Sti has a factory recall on the expensive inlet. |

Hey Vlad, very informative thread!
I do have one question though, I'm in the process of getting ready for a V7 swap and I got a bare V7 intake manifold. Can I just swap in the throttle body, IACV, TPS, etc. from my ej205? Thanks! |

The IACV you can, I know I replaced that and the part number was the same with an 02-04 WRX.
The throttle body may be different, I know that the heater lower conduit seemed to pop in a different spot than my WRX, when I did the heater deletion mod. Anyway, some more info added, the process of improvement continues.. |

What USDM clutch can be used with a ej207 and ver7 non dccd 6spd? I've been looking around and read that the 2004 USDM STi clutch can be used is this correct?

I'm more tempted to move forward and make more information available of the V10, GRB bodystyle.
As things are, I think I posted several times that one should take a step back and count how many years old a V7 is and how much money they end up costing, for how old they are. My personal opinion is that no junkyard, 10+ years old engine, should cost $3000+ I am struggling with the thought that this very thread can be an instrument for the prices to continue to be where they are. These are engines that sat in a junkyard, possibly after a colision, maybe a serious accident and did not even turn for more than 5-7 years. I was thinking in the past, that classic car first start-up rules should apply: Take the spark plugs out and spray WD40, a thin film, turn it by hand couple times, etc.. And people want to buy these and begin running double the designed horsepower from day one... So yes, we have to move forward in time, to the newer engines, sorry.

Big port heads which are on V7,V8 or V9 have usually part number on heads LHS20 or RHS20) Spec C in opposite way using different part number(LHT20 or RHT20,but some people saying they're using LHC20 or RHC20,but we are bought S204 heads which have part number as above LHT/RHT) But from v7 JDM WRX(EJ205) using same Big port heads just there is difference mainly in cams which are used Hope this help Jura |

In any case, GDB Type RA and Spec C Type RA are two different cars. There is nothing for me to choose, because they are different timeline wise and engine wise. Type RA uses a different cams than Spec C in revision A. They should not be confused. Also, "big port" is a vague designation. All the JDM Sti are "big port". If you look in my posting, you will see that, although the Type RA (and NOT the later Spec C Type RA), already had big ports, they did an additional radius smoothing. Take a look at the technical drawing provided, it will help with ID-ing those engines. Now, as far as the Type RA and Spec C Type RA having different heads than their contemporary JDM Sti, this is incorrect. All you have to do is go and look up the part numbers for, by example: 2001 JDM Sti and 2001 JDM Sti Type RA 1139AB370. Same part number. Now the radius smoothing was a process said to be done after the heads were machined. If you meant to compare the Spec C with an UKDM Sti, please specify this, otherwise causes confusion. The LHS and RHS are casting and assembly codes, but not part numbers. A Subaru Part number has a format as the example above (1139AB370). Using these instead of part numbers is a good atempt of creating useful information for enthusiasts, if you have more info of this nature please post it. It's possible that some in UK consider thet the UKDM EJ207 from an UKDM Sti and the same year JDM EJ207 from a JDM Sti, are one and the same engine., but they are not. By example: First Sti Type UK in '02 had heads: 1109AB440 The '02 JDM Sti 1109AB370 Last edited by Vlad; 01-29-2013 at 02:28 PM. |

Agreed all JDM STi heads are Big Port,but you cannot forget on JDM WRX which from V7 using AVCS and are Big port,although they're have different cams(i've run before on our 20k wagon JDM WRX AVCS heads,which has been Big Port) UKDM STi using small port heads as on USDM,cams are different,although they're interchangeable(you can use JDM STi cams in UKDM) Agreed GDB STi Type RA and Spec C Type RA are two different cars,Spec C Type RA using VF34 and Type RA has used VF30 as S202 STi,JDM STi v7 I''ve just been confused with the Type RA In heads compartment would say,Spec C single scroll or Twin scroll heads are different for sure in ports etc. About the ID drawing,good work I've at home 3 pair of the JDM Big port heads which suffered as every 2.0L with cracking around the spark plugs,last set is S204 which have clean faces and no cracking LHS20/RHS20 or RHC20/LHC20 is not part number,but with this is much easier to see difference,if you are going to buy some heads yourself and from this you will know what they're.This is usually stamped on the heads above the ports No UKDM or any other EJ207 is different from JDM EJ207,heads are not the same as I said they're small port,cams are different etc Jura |

So, I decided to update the GRB section.
As more people will become involved wit the GRB EJ207, the knowledge base will increase, hopefully we will have the same amount of info as for the GDB |

Any info on the ver6 ej207dw2pr would be awesome! I just bought a complete ver6 STi RA Half-cut with everything, basically the whole car. It just had to be cut to come into the states unfortunately.
But yeah, any info on the ver6 ej207 would be cool. I just wanna know more about the internals. I think they are forged , but not 100% on that, so it would.be sweet to get more information! |

More GRB info added.
Sorry, V6 is not in my scope. Those are older engines and more likely to have problems. If I was to put the time and effort into researching that and would publish a comprehensive article about it, the engine dismantlers and vendors would read this, conclude that it is easy to swap these in now and raise the price for these. This in turn, would cause others to not buy V6 anymore and this would make the research useless. |

Just thought I'd add some info:
Quote:
Crank sensors are the same, no issues there. Passenger side sensor bolt-hole needs to be slotted and o-ring swapped(or not; the VR o-ring is pretty thick and requires a lot of force to push in). Driver's side sensor needs to be pushed a little further back. Everybody has milled the head and use the stock sensor, but I opted for a smaller diameter aftermarket hall sensor mounted offset in the original bore(trimmed nylon bushing with a rubber washer to act as a seal under it; bracket sits on top of that and had to use a longer bolt+spacers to clamp it down). The sensor I chose is a little long and touches the TGV housing.... though seems to be working fine(Sorry for the crappy cellphone pics)! |

-Yes, the crank sensors are the same.
-I guess you can say that; but in that case I should mention that the coolant temp sensor uses a different plug(if you're reusing the 32-bit harness) so either the connector has to be swapped or the sensor does. -Yes, the intake cam sensors. -Currently running on a 2005 LGT ECU; 32-bit, with EGT disabled.

I can only say they're the same as the 2002 and 2005 USDM WRX since those were the only ROMs I checked.

This has been the understanding, as far as the front oxygen sensor, use a 16bit front sensor, so from a WRX '02-'05.
