Does anyone have experience of them? I'm toying with getting one for an engine conversion, I want around 300bhp and thought it would be cheaper than getting an STI as I need the whole car for the loom etc., I've seen the legacy's go on ebay for £700+ for the whole car which is considerably cheaper than an STI, any advice would be greatly appreciated

Bob,

Are you -
1. Buying the Leggy for the engine to put in an Impreza STi?
I think the looms are different and the ECU will definetly need work or replacing with a TT Leggy one.
2. Are you converting a Leggy to twin turbo?
As above.

The conversion cost may push it toward a V3/4 STi with 260BHP as standard. 300BHP is only a short tweak away.

It's going in a non Subaru car so I need the donor car, a legacy TT would be cheaper than an STI especially as I wouldn't use the STI brakes, suspension and the other goodies etc.

Thanks for the link

Extra link added.

Excellent, cheers!

Does the legacy TT have the same mounts and gearbox as the Impreza? If it's essentially an EJ20 with another turbo and associated plumbing I might try a test fit with a knackered motor first

Hi.
The Legacy EJ20R blocks run 280bhp, and are not tunable.
No-one can remap them yet, it is being worked on, but not available yet.

Engine and Gearbox mounts are identical.
There is one extra mount for the N/S Downpipe, but cant see that being hard to make.

If you are doing a custom job then maybe look at doing a single turbo conversion, that way you can run Impreza V3 STi ECU... parts needs would be things like intake mani, turbo, headers+up-pipe, downpipe... and more importantly it would be re-mappable

Bobfrog

Interesting! I'm guessing the cost of the sti v3 ancillaries and ECU would bump up the cost of the conversion by quite a bit though, I know it's not going to be a sub £1000 conversion but I need to do it for a reasonably small amount because I have other projects to get finished too. I'll certainly bare that in mind though because I can get the single turbo legacy engine in then faff about with the STi v3 bits at a later date

Bob Rawle is good with TT Legacy's

From Bob's website.

In the early days of our evolution, we started with the ubiquitous Link (PossumLink) engine management system from New Zealand. Then we mastered the high-end MoteC solution. Gradually, we familiarised ourselves with a wide range of engine management products available for Subaru and Mitsubishi performance cars and chose to work with those we deemed good enough to provide the results we would expect to achieve. Not such a long time ago, we proudly adopted the very first British solution of the kind – EcuTek – which enabled us to further stretch the envelope of possibilities, while retaining the original, manufacturer's ecu (engine control unit) as a starting point. We have developed a particular expertise in this area, including even the extremely difficult Subaru Legacy B4 Twin Turbo.


V3 STi's are only mappable after the ECU is modded.

Weighing the costs/work/benefits up of buying the STi parts, ECU and having the ECU modded I'd rather use a TT motor so in the short term I run around with 280bhp and spend £650ish on megasquirting if I want more power that way I get 95% of what I want straight away, I have a smoother power delivery (it will be RWD with a ghetto welded centre diff for now) and a fully mappable ECU

Is it going in a Beetle/VW van?

think i might have misunderstood what year of legacy you were looking at...
-if you are looking at a phase one, single turbo unit, you will be fine...
-i thought you were looking at a phase two BG5 Twin Turbo unit, they arent that great, cant be mapped etc...
-or like Blue Dragoon says the B4 (BH5 chasis) engine and ECU can be mapped... but i imagine still very pricey

Bobfrog

Nope, e36 bmw, I've taken preliminary measurements and it looks like it'll fit, I'll try a test fit when I have a weekend to pull the motor out, the steering column looks like it won't foul anything as it's off to the side much like the scoob, the cross member location will make or break the conversion I think but the ej20 only has a little sump so fingers crossed!

I have thought about putting a 325 motor in then turboing that (it's a 318is), it'll be easier and definitely fit but a lot more expensive and I like putting different engines in cars anyway, it's more fun

If I can test fit a knackered engine and gearbox (JimbobWRX might have one) and it fits I'll buy the legacy and crack on, if not I just pop the 1.8 engine back in and I've not lost any money

Bobfrog

The ones I've seen for the money I want to spend are 1994 models, they're ranging from £700 to £1000 for a runner with a few scabs on the bodywork here and there, the worse the bodywork the cheaper it'd be for me!

I think you have to have a word with Bob Rawle both in terms of what can be done and price.

Bobfrog

If the test fit goes well I might well give him a call to see what the engine options are

Cheers

and the range of Legacy they can now handle and at what price.
I think because they are not straight forward and Bob enjoys a challenge, he has made them a challenge.
There is a specialist Legacy forum if you look for it.

Here's the US site, there are some serious techno's on here.

I've asked some questions on the UKLegacy site, it seems there are quite a few different ECU's people use from reading it today

Thanks to JimbobWRX I measured this today, the e36 chassis rails are not as wide as I'd imagined, I only noticed when the measuring tape came out....
