WRX/SUBARU Engine Conversion
BU90FF - March 9th, 2006 at 11:57 AM

Hey Everyone,

There are plenty of post about people using Subaru engines etc and but no one has actualy mentioned where or who is doing the job.

I am a proud owner of the of a 56 oval and am very interested in a wrx engine conversion. I am in sydney and if anybody knows who i can speak to or be pointed in a direction it would be much appreciated.

Cheers BIG ZEE

Do you want to do the conversion yourself or have it done by others?


VWCOOL - March 9th, 2006 at 01:28 PM

I'll start:
Is your Oval standard? Do you know roughly what's involved (body mods, radiator, brakes, ballpark costs etc?)

edit: Speedster beat me!

I did my own, using Custom Off Road components. That is to suit EJ22 into Bay Bus


BU90FF - March 9th, 2006 at 04:46 PM

Im going to find out exactly what mods have been done to the oval etc.

i am looking at getting it done somewhere if i can, but if need be i can do it myself.

not sure wat needs to be done or whats needed or how much but it doesnt matter.

Im prepared to divorce the wife and sell the kids

Do a search one here, for EJ20t into bug, Jak, Matt (Boof) and Paul (1303) all have good build threads on this forum (Pauls' is on the members rides section and I only just found it!)

The big thing to look for is getting the correct WRX motor with good heads .Subaru motors ( EJ series & WRX ) have some big issues with lifters .some of the above had had issues all ready .

I have just picked up a 94 wrx donk & looking to see if the heads are good .I am going to strip the motor down before I put in a ride .

welcome to the other side :vader

:sniffle:
I thought the whole "thing' revolved around being more reliable than VW.

Definitley more reliable than the average VW motor. Based on age more than design though.

EJ series motors and peripherals are generally less than 10 years old.

VW aircooled motors and peripherals are generally more than 30 years old.

It is also about power. If you draw 160+ HP from a type 1 VW engine it will not be reliable. You are exceeding the capabilities of the cooling system that was designed for 60HP max.

The Subaru will make that power all day long, as it was designed to do so.

OTOH, if I had an oval, I probably wouldn't be looking to drop a subaru into it. I'd be restoring it unless it is _really_ far gone.

helbus - March 10th, 2006 at 07:24 AM

Very good point George. That is one point it it easy to agree on.


VWCOOL - March 10th, 2006 at 07:37 AM

Yep - and compared to later models and in consideration of a Subie transplant, the engine bay is too small and the suspension is spindly and can't be made to handle and the brakes suck and the doors latches are crook and the gerabox is weak and the chassis is flexy and the windscreen wipers are crap

Does anybody know anyone in the sydney area i can speak to. Thanks for all the tips fellas


malcolm - March 10th, 2006 at 08:54 PM

try and get a 99 mod wrx front cut .


seagull - March 10th, 2006 at 09:13 PM

my whole rs front cut cost $1800.00 , I am using the auto ( in my liberty )


boof2332 - March 11th, 2006 at 06:15 PM

Please call me 0416115993.
I am doing them on request. Have just finished another one for a friend, still have the 914 to complete(not far off) as well as the oval that is hanging in the garage. I now have a workshop for the conversions/fibreglassing/spraypainting so the garage can return to some normality....well as normal as can be with subaru powered vw's and porsches everywhere.

Matt

P.S. I will have a heap of fibreglass W decklids moulded soon if anyone is interested.


BU90FF - March 12th, 2006 at 08:50 AM

NO Probz BOOF ill be intouch soon. hopefully i can get this little transformation started.


Jak Rizzo - March 12th, 2006 at 02:22 PM

I'd be quite interested if u can actually get one in the back of an oval. My superbug is an extremely snug fit & thats with the gearbox moved forward 2 inches. My mate has difficulty getting his twin webbered 1914 in his 56 engine bay.
Another issue to think about with a wrx/Oval transplant is the weight. 860kg is the minimum u can have with the ej20t, my mates oval is about 760kg & thats on a later IRS chassis. I only gained 60kg when I did my conversion.
Just something for u to think about.
regards
Jak


Baja Wes - March 12th, 2006 at 06:41 PM

Actually the minimum is 800kg.
2.5 x 800 = 2000cc turbo

but then once you get to 800kg you are into the 2.75 rule so it actually becomes more.

the way to do it in an oval would be to put the oval body on a late model pan, so you can use the weight associated with the later pans chassis number.


boof2332 - March 12th, 2006 at 10:16 PM

Ill be putting my 54 body on the white car soon, or maybe build a totally new pan for it...either way i'm sure it will fit The oval engine bay looks smaller as it had to meet up with a 36hp motor. Cut out the unnecessary metal and all should be cool...

Our Engineer & the RTA in NSW said that it was 860kg minimum. Maybe QLD is different?

Hi Jak,

For NSW you can either use the old RTA rules here;
http://www.rta.nsw.gov.au/registration/downloads/vsi/vsi06.pdf
Look on page 3 and you will see the 2.5 x weight in kg = engine size in cc rule.

The 2.75 for over 800kg rule is a new one from the new national code of practice for light vehicle modification, which NSW should have now adopted. See the national code of practice post for more info.
