DIY Turbo upgrade project

New TD06 bolt on direct entry compressor housing / TD05 90 degree




Flip side -





20G compressor wheel / Std 'small' 16G compressor wheel





Modified exhaust housing to improve spool up and minimise lag



The main turbine discharge area is ported to remove steps and allow gradual expansion of the exhaust gasses directly into the main 3" downpipe.
This set up is to mate to a twin dump downpipe where the wastegate gasses go down a separate pipe which rejoins the main pipe at a shallow angle near the bottom of the downpipe.


Compressor maps show 20% more flow at 4% higher efficiency than the 16G

Projects forum..... we have got one. I've already learnt how to wall paper my walls and put up a curtain rail..... brilliant. Oh sorry you actually mean a project forum to do with Subaru's.... your on the wrong bbs. Try 22b .

Looks very interesting Andy.

Tony.

Nice pics andy....I must admit I'd love to see beyond those white garage doors now. I can only assume its like a WRX RA graveyard with bits of engine everywhere As a non-getyourhandsdirty type I really appreciate pics of the various engine bits to give me an idea for what they look like.

Thumbs up

Cheers Kenny

I never knew that a wee scooby engine could take up 30 feet of bench !!!

 

Andy,
Pity i didn't know before putting on md 304.

 

nice on andy, I spoke to you about this a while ago, but I was talking about the 18g.. nutter


interested to do a comparison on my hybrid with regards to lag.. ill try and shove it on for well lane..

David

 

But what about those of us who want a Turbo that can flow circa 450-500bhp?... any suggestions......... without sacrificing too much lag?

 

Speak to Mark, he has something jst up your street Steve, good value, low hassle, good power.

Paul

 

Does anyone know of other car manufacturers turbo parts (same make of turbo obviously) that fit the scoob ones(td05)

What I mean is I once used a saab turbo exh comp housing on a T2 garret on a 'home brewed turbo conversion, I got it from a scrappy for peanuts. Would have cost me bout £250 new.

Just wondered if you ever use parts like this or just buy new?

I mean those parts have been designed for another vehicle (small truck perhaps?) and there are things like that sitting in scrap yards

 

Good thing with Mitsubishi turbo's is that everything seems to be available to buy....at reasonable prices

Doesn't the Evo td05 spin in the opposite direction?

Richard

 

yes they spin backwards on the EVOs. But not on the US DSMs and Talons that much of the turbo stuff (over there) is available for.

There are about half a dozen companies that do a good range of turbo conversions for the TD05.

paul

 

IIRC, only the 5,6 and 7 are reverse spin. I believe the early ones also used a TD05 but not all of them had the 'big' 16G.

Still, not many of them in the scrap yards

not sure about the similar money bit?? Unsure on price, but very nice...












David

 

David,

Looking at the last photo, how much has the exhaust inlet port been opened up on your TD05 hybrid?

It'll be interesting to see how these 2 very different TD05 hybrids perform.

Andrew...

 

And my one will be without Nitrous Oxide spooling it

Re: 'similar money' I meant for a std TD05 16G, I think yours David has a garrett compressor wheel in it ???

[Edited by Andy.F - 12/30/2002 3:24:43 PM]

 

Nitrous Oxide? David, you should run with and without it! to see the true benefits of using it! Just make sure it doesn't run out of gas!!

 

looks like DW has a big straight entry intake too.

61mm?

[Edited by T-uk - 12/30/2002 3:47:38 PM]

 

a bit like mine, but mines nicer

 

dont think it is any nicer... my photos do no justice... Ill take some more sometime

David

 

 

top.

 

Fecking Hell. Go away for Christmas and this happens. Andy that compressor wheel is huge.

 

Andy F,

"If only we had a 'projects' forum "

Have you, perchance, visited bbs.22b.com lately? IIRC, there might be exactly the forum you are after sitting there.

Moray

 

Steven,

when I pointed out to Andy that the 20G was larger than Shropshire he got all upset

See you Monday.

Trout

 

Yea, cos Shropshire ain't that big

 

Is getting a turbo of similar dimesions to the Tyne Tunnel

Nice to see your sense of humour is back Andy

Trout

 

Not concerned with comparing size, as long as it flows better

 

Andy,

Just curious, but the TD06 cover looks like it's too big to fit in the stock location, are you making a custom up, and down pipe for it ?

Also, what are you doing for the actuator ?

Mark.

 

Although I have not actually mounted it yet I'm fairly sure it will fit in .......watch this space !

After all, when one can walk on water, how hard can this be

I had offered it up and all that would appear to be close was the original FPR....which I don't have
The wastegate actuator will require a longer rod and one bolt hole relocating.

Andy

 

I'm lookin for a TD05 if anyone has one for sale to fit to a USDM WRX after machining the compressor inlet of course. Please let me know if you can help me out.
