I just bought a 1996 WRX RA engine with 5th injector and closed deck block... Apparently they do exist.

Right, but not off the standard production line. We've talked about this before. You could order most anything off the "menu" back then but it would not be correct to say that as a general rule 1996 RA's came with a 5th injector. That's a special option by order, not the basic spec that the majority of the cars were built to.

Yes, I think the option code for a closed deck block was 62C.

Why won't 207 heads run with a G ECU? I just bought a second motor (V6 WRX RA) and was hoping to drop in straight into my V2 STi RA (with SB ECU). Won't this work?

There are a number of things that affect ecu interchangeability... probably the biggest issue with using EJ207 heads with a EJ20G ecu is valve train timing. Cam gears (and their timing pickups) change from time to time. The crank gear could have a diff number of teeth, the sensors on the intake manifold could be a different number of pins.

I won't say it's impossible, but it will probably take a significant amount of effort to modify things to the point they work. I definitely believe it won't work out of the box...

If you really want to go down that road, I know a guy that can help you... but it's not going to be easy, and it might just not work.

Thanks for that. This is a little trickier than I thought... Looks like I should run the A7 ECU that came with this motor. Anyone know anything about the A7? Is that the pick for these V6 RA engines?

I know with those early G engines, the 6K, 7K SA or SB ecu's are good. Lots to pick from there.

ok so no word of a lie there is a big lack of information on how strong are the ej20k ...... like alot of people say they swear by the ej20k but uummmm what do u swear by on them in the sense what power Hp did u push through it ??

cant find anyone pushing stock ej20k to 400awhp....ive seen more ej20g been pushed to 430 to even 520 awhp stock block stock heads......but it was the new ej20g from the bug eye onwords....

Im asking from the bottom of my heart Nasioc people... please please let me know if u have ej20k and what power u pushed it ...

i have a old ej20k stock heads but 03 sti bottem end internals inside ej20k block.....and please let me tell u my experince ....5 cases where oil and water mixed in oil pan......all 5 times had to drive it for 16km home.....i drive it hard and very very hard in 5th gear love getting to 220km ....has vf22 fullTBE Headers 22b tmic and thats pretty much it.....still puzzeld as to seeing heaps and heaps of people saying u need biger injectors for vf22....still using stock gray wrx injectors.... anyways havent spun a bearing and it dosnt sound like engine is on its way....

i really want to know whats the max awhp ej20k can take ? i think there only good for 340awhp

I've been waiting for quite some time for my EJ20g to blow or wear out so I can go to a Ej25 block with EJ25D heads. Problem is, it just keeps running. I've had it 5 years now, rip it good, long highway miles, up and down mountains, off roading, and nothing still runs like a top. I'm going to upgrade from my TD04l-19t to a twin scroll TD05 or VF37 and see if pushing more power will kill it.

As everyone as said on here, it's really tuning as there aren't good tuning options for the 20K. Just need rob to release his Z32 MAF tune

I'm also hoping Rob releases his Z32 MAF tune (for the EJ20G), as this will hopefully lead to Rob being able to have another look at the EJ20K... as mentioned by Rob at his website Here.

If you're an EJ20K owner, it probably wouldn't hurt to let Rob know that you'd love to have him develop a tune for us.

Any reason why the daughter board from ESL isn't a good tuning option? It seems to offer just about everything a new ECU or even a stand alone does in terms of tuning? The reason I am asking is because I am considering buying one.

I'm a newb with Subarus, and I know next to nothing about any of this... but I can still offer a thread for you to have a look at Here. Yes, it's a few years old, but I believe it at least demonstrates a potential pitfall with the implementation of an ESL board.

On the other hand, I've read nothing but good things about RobTune... so I'm hoping he eventually develops something for the EJ20K.

Thanks for the thread Vancouver98sti. Sounds like the boards can be kind of a crap shoot. I am guessing that no one in Texas has any experience with these boards, so I would probably get charged out the *** for a tuner to learn the system.

How has the greddy management system worked for you whiterabbit? Is the system common enough for most tuners to use it? And what did you do about the lists of the MAF? Also, I know you have been asking about the max HP for the ej20k (V4?) motor recently, and I am also looking forward to an answer.

trust me when i say this brother the ESL daught boards are pimp i cant belive there that good ...e-manager only found 1 tunner in Melbourne Australia thatz why i went with it and he puts down some good figures with other cars so i would go with him..... problem with E-manager is its piggy back and somtimes has to fight with the factory ecu to do its thing ..... where as the Esl is full stand Alone......long story short a few rally gc8s had the stock ecu modif3d like the Esl and put some haltch and motech tuners to shame ..... thats why i knew the stock wrx ecus are very good if tuneable and Confirmend with XLUBEN nasioc memeber cranking 9sec 1/4 with stock ecu ..... if u find a tuner that knows ESL go with it man its a pimp board ....

ill let u know how i go with my e-manager soon just need to fix some boost leaks and tune time.....ill send u a message
