well i convinced some one else to, suburize Options

A plug and play wiring adapter would be great, but because there are many differences in the model years in terms of sensors, locations, ECUs, etc., it would be hard to make a generic one. I'm considering however making up some printed circuit boards which would replace the stock relay board and provide simulation of the unused sensors for the Subaru ECU. It will hopefully take out some of the complexity of doing a conversion, but not all of it.

But if someone took the "best" engine for the 914, say the EJ20t out of a wrx, with the most plentiful supply and made that adapter, those looking for just a subaru conversion wouldnt have to worry about what block. If you're a renegade and want to do an ej20tt or an ej25t or something you can do your own wiring, but Im willing to bet most people are looking for a subaru engine conversion, not a specific engine.

[TonyAKAVW]

Well, the EJ20t even has differences in the model years. They are probably not big enough that a common board couldn't be made however. Its probalby a good idea actually. Make a board for the WRX motor and one for the 2.5 (which has a SOHC and DOHC version and many differences in the model years as well). (IMG:http://www.914world.com/bbs2/html/emoticons/idea.gif)

more subaru (IMG:http://www.914world.com/bbs2/html/emoticons/smilie_pokal.gif) the engine ej20t will fit with NO body mods whatsoever, engine and gearbox will also go, disengaging the rear drive clutchpack which are electronically controlled and placing a welch plug into the the rear output stops the oil problem ,
i hope that somone in the us builds a kit for these soon so the mounting is made simple for the average joe.
we have done two diffrent wiring styles one was a graft of an aftermarket ecu to the suby engine loom this was on a 94 model the other has been a complete ecu flying loom which comes with its own sensors on an 05 sti corsa bitumen motor and six speed cost of computer is approx aus$1600 and comes with hand controller also maybe this is an option that tony could look at.
my biggest consern is the drive shafts any ideas ,we have a hybrid 914suby setup but strength ???????

We just worked on a 400+ hp suby powered sand car that spanks $100k+ LS6 V8 powered cars all day long. Owner said it was approaching 500hp, lots of money to get there though.

my need of info on possible shaft theories is of importance to my end result.
[QUOTE] Owner said it was approaching 500hp, lots of money to get there though
i was looking at a site here and they are getting almost 500 hp at the wheels from an ej20 in a subaru brumby ute see it at tony rigoli performance (trp) they are now moving on to the us scene, the modifications they are doing is nuts

[eric914]

Add me to the list. In the last week I bought an EJ20T Subaru motor, the Kennedy adaptor kit, and their stage 2 clutch assembly.

I am in the process of liquidating all my type 4 stuff. The more I though about it the less I liked spending lots of time and money for 120Hp at the most from my 2L type 4. With the Subaru I will get 227hp stock and the block can handle more on the stock internals with some modifications.

I can't wait for the rush of 227hp in a 2200lb car.

i have heard that the cat before the turbo when bypassed adds like 20 hp. i dont know if suby ever changed the design to do away with it thou

[Kostamojen]

The catless uppipe does add some HP, not a super lot but some. Aftermarket uppipes with larger diameters and better designs tend to do a bit more. There have been a few issues with the pre-turbo cat causing premature turbo failures due to pieces of the cat material being sucked into the turbo (the 2006 subaru turbo motors are no longer using the pre-turbo cat and are instead using a pump-type emissions system).

Right now there are alot of companies putting out 400-550whp kits for WRX's and STI's but that stuff does get quite expensive (its said for over 400whp you need internal work done... forged pistons and such, better heads, cams, etc.). The good news about all this is the sheer number of options that simply were not availible 4 or 5 years ago (even 2 years ago). Another plus with this means there are ALOT of OEM parts floating around, so if you choose say a EJ20T you can find an STI intercooler, injectors, even the stock STI turbo for very little and have yourself a ~300hp motor without too much effort.

If you really want to do this on a small budget, I just had a friend who found one of the early 90's legacy turbo's at a pick n' pull and he bought the whole motor/etc. out of there for like $200. The ej22t actually has probably the best shortblock subaru ever made. The heads are SOHC and not worth mentioning, but even with that block you can use an old TD05-16g from one of the JDM EJ20G motors (which can be had for ~$300) and a WRX/STI intercooler along with some engine management and again have a ~300hp subie motor for next to nothing.

As far as whether a 914 tranny can handle all that, I have no idea. Transmissions are the weak point in Subarus too but for different reasons (AWD = Grip, Grip + Massive TQ = Blown stock tranny). Axles havent been too much of an issue for subaru transmissions though, but my thinking is that if you kept the power within reasonable limits and not too much initial torque from the motor maybe the axles will hold up? Im sure it would be an easier motor to deal with in that reguards compaired to some of the V8's that people have used.
