Impreza EZ30 Swap

[Subru]

I have been thinking (again lol) about an EZ30/36 swap in an Impreza/wrx body.

Done some research and seem like its a case of finding an EZ30 with gearbox, modify wiring to suit the body to the engine, aftermarket ECU(?) and modify radiator location.

I assume there would also be other stuff like fuel pumps I may need to upgrade too.

Has anyone had experience with a swap like this and is it as easy as it sounds? I like the idea of being able to do a swap by myself with basic tools and not needing a shop to make custom mounts etc.

Maybe have a chat to possumborne. Not sure how much of the build they did but they had a late model one that was converted to a H6 just recently up there. Was going for big power so imagine the build price was extraordinary.

 

What's the end goal? Adding a turbo to it or staying N/A?

 

You’ll be talking a fair bit of custom stuff To get things fitting since a H6 has never been offered for an impreza. Not sure why you’d need a new gearbox, your current 6mt will fit up to it.

search this forum for notawhiteGTB's diy guide : tis GREAT

 

(I'll try now too)

 

EDIT : FOUND

 

it does start off life into a BG5 GTB then into a Type R that then gets a widebody treatment <3

I was not thinking about my car. I was thinking about a gc gf chassie impreza and just having an NA H6 in there. Nothing too special.

Im not sure if the factory gearboxes from the 1.6-1.8na gearboxes will handle the torque of an H6 unless I could find a wrx or sti with no engine.

@Joker cheers ill take a look tonight.

Clint's car was super cool. You could probably just get away with an old GTB gearbox.

[J CHILN]

ever seen the mighty car mod videos of them doing the work to theirs? pretty good plus on the skid factory they put one into another car also

[Subru]

Yeah MCM's was in a legacy with a turbos and and stuff. That build was pretty cool.

Marty's daily - SuperGramps.

It's a EZ36 with a Garret turbo (can't remember turbo model).

 

 

This guy in NZ did a EZ30 out of a BL/BP Legacy with a 6 speed into a old Impreza wagon.

Runs a Link G4 ECU. Few videos on his channel about it.

 

I seriously think you should consider this swap though... 13B Impreza 

 

If you are totally seriously, you need to do the BL/BP EZ30, because of the 3 exhaust port heads and AVCS that the BE/BH (first gen EZ30) didn't get.

I've always wanted to do something similar, but BP wagon manual, Centrifugal Supercharger, FlexFuel, and thats that. Be a wicked daily/road trip car in my opinion.

Haha 13b wouldnt be difficult or expensive . Would be cool tho lol

[ginganinja]

13b impreza has been done. Was a track car.

 

Also therebis an EG33 engine for sale on tm atm.

[Subru]

Yeah eg33 seems to be more popular swap into imprezas. Unless in america they are easier to get.

Only need to watch andy Forrest videos for inspiration for eg33 build. Go all out a twin turbo it.

I was thinking a little GC Impreza with a plain old EZ30 w/factory ECU would be a fun daily driver. And pretty good on gas. It doesn't need to be a rocketship drag queen.

[Andy_Mac]

The older single ex port BE/BH 3.0’s should work a treat on a stock ECU. BL/BP ones are considerably more complicated and would need a crap tonne of electrical know-how to get running without a Link, if possible at all...

[McMatty]

Should have had this idea last week, there was a deregistered 3.0 manual BP on trademe for $1200, would have saved a bit of cash

I was thinking the same, a whole bunch of torque everywhere and no lag with a nice 6 cylinder exhaust noise to go with it, perfect daily.

Even my Sti is a bit annoying to daily because its just warmed up when I get to work 15 mins away so I have to baby it the whole way off boost.

The guy in NZ that did the BL/BP EZ30 swap into a GC chassis used a Link G4+. Mind you, that car took him like 5 years lol.

The EZ30 from the BL/BP is more complicated due to having AVCS (& AVLS?) on the intake cam. Plus it has Drive By Wire Throttle and all that economy stuff, that you basically remap to be like a cable throttle.

I've thought about doing this swap myself, into a BH Legacy - kinda like @whitebait19's Lancaster, but with the BL/BP EZ30 and a 6 speed.

Seeing that beautiful car around town a fair bit doesn't help with the temptation too

With a link wouldn't be an issue at all but the cost starts to really blow out once you start going down that route

Once you start modifying a car, it starts getting expensive.

A mate has done it recently into a bc5, took him a month or two but knows what he is doing and has the tools.

 

Made a radiator top joiner/cross over pipe so he could use a factory rad, seems to be working.

Link g4 extreme, wired using factory engine loom and link a/b looms

Falcon throttle body (bolt on i think), unsure on what throttle cable he used.

 

Still not cheap.

[Subru]

yeah, would be a cool build to do one day when I have the room and time.

In the mean time im looking at buying a Mini as investment/project car.

Which EZ30 did he use? The first gen (came in BE/BH), or 2nd gen (BL/BP)?

[pl0x]

ez30r / 2nd gen

 

1st gen shouldn't even be considered a ez30
