Looking into a TD04 Hybrid turbo, just wondered how much boost do I require?

Looking for about 280-300 bhp.

 

assuming you don't mean the big TD04, 1.4 bar standard limit for a tuned standard engine usually- very quick spool

 

I'm getting my TD04 turned into a hybrid.

 

Just get a 19T conversion done, same characteristics as a stock td04 with mild porting and billet wheel. 1.3 bar typically sees 300-310, close to 320 at 1.5 with the correct supporting mods

 

Ah ok, never heard of 19T conversion to be honest. Like video below?

 

Yes, as above. I'm looking to do similar myself but I need to find where is best to get the parts - would prefer a UK supplier to a US one.

 

So whats the power delivery like with one of these? Anyone currently running one?

 

If you're around south London I can take you out in mine.

 

Billet wheel,polished and ported. Td04

 

Nice, who did that for you?

I wish i was down London way but i'm afraid i'm not , cheers for the offer though.

 

It was turbo dynamics that did it.
Some people on here think I paid too much at 500 but they only offered up Facebook turbo builders as an alternative.
I'm very happy with it. It comes back like a new turbo with a test sheet etc.
Also one years warranty.
Could you buy a new turbo for 500?
I doubt it.
It's basically in between td04 and td05.
I've had both and this is the best of both worlds.
I live in London and need the low down grunt and pull of the td04 hybrid.
Strangley if you call turbo dynamics they don't hybrid the td04 but it's called something else.

Ah ok, i've had both aswell, and the TD05 lag didn't bother me, gives that extra sensation of speed, and as i only use mine as a weekend car. £500 does seem quite abit, i have been quoted something not far of that though, think in £400 area.

I don't want to spend silly amounts of money as i could just get a VF35 for less, which sounds similar to the TD05 with less lag people say. As for the TD04 hybrid just wondering how much boost i'd need to be running?

 

Mine would of been cheaper but I had everything done to it like ported and polished.think that added about 80 quid.
I did originally buy a used vf35 and payed to have it fitted and mapped but it turned out to be a dog and smokey.
So had to get my money back.
After that I didn't want any more issues so sent my td04 off.

 

I'm pretty sure mine was mapped at 1.35 boost.
It was done by rich at fb.

 

Any chance of a picture of any porting you can see? Be interested to see how much/where they take it off...

Thanks, Paul

 

 

Those are the only 2 pictures I took of turbo.

 

Looks very smart, what bhp are you running? thanks

 

Haven't had it on the dyno mate.
Rich said around the 300 mark when he mapped it.

 

Can someone point me into the correct direction in buying one of these 19T conversion kits?

 

I'm leaning towards the ARD kit, as no machining is required. Might also get a turbine wheel, as it remove the need for balancing.

I'm considering this:

With one of these:

And the rebuild kit too:

You don't need to machine the CHRA with their kit and it won't need balancing if you get the turbine & compressor together.

They do a 9 blade turbine also but I'm not sure if it's worth it as it increases spool by 500rpms.

 

Wow that looks ace, cheers for links.

 

Maybe I'll wait for you to build yours first before I spend any money

 

I think you'll still be looking at £400+ depending on whether you are buying a donor TD04, ceramic coating the exhaust housing etc. So considerably more than second hand VF35.

However, you can't rebuild the VF series turbos (not cheaply anyway), whereas you can with the TD range. So I think it's worth paying extra to have a fully rebuilt turbo, that would be a lot cheaper than a new VF35 etc.

You could do it really cheaply and simply swap the compressor and housing on the TD04. Depends whether you are happy pulling out the turbo and refitting it yourself, if it lets go.

Ultimately I'm looking for the response of the TD04 and I like the idea that it can be customised and fully rebuilt to your spec. Plus I want something else to tinker with myself, rather than just throwing money at someone else to do it for me (and trust that they have done it properly). And I'm intrigued to see the results once mapped.

I'm in no doubt that a second hand TD05/VF will yield more headline BHP and be cheaper initially but I think I'll wait to go down that path once the day comes to rebuild my engine.

 

Didn't think of the cost of a rebuild kit aswell, this could end up costing as much as a VF35 at this rate. Unsure of current condition of my turbo.

I'm thinking of buying a TD04 to practice on, once i've done that, swap with current turbo, then rebuild that aswell. Only thing i'm unsure of is how it will deliver the power, i'm not worried about abit of turbo lag, but i prefer the delivery of the power to be hard, of course a map will help with that aswell.

 

I've just bought a TD04 to use as a donor, rather than swapping mine out.

As I say, you could just fit the housing and compressor, which is about £180. Seems a bit daft not to rebuild it whilst you are pulling it apart. I've seen rebuild kits as cheap as £40 but not sure how reliable aftermarket parts are.

A VF35 will work out cheaper second hand but you can't rebuild them. So it's a gamble. Plenty of people here have bought and fitted with no issue. But then many have also had to buy twice. If you are also paying twice for install....

If you want a big dollop of power all at once, then I would suggest getting a TD05 rather than a TD04. You'll need it converted to front entry (if you don't find one already) but you can buy converted housings. TD05's can also be rebuilt and you can change turbine & compressor wheels exactly the same as the TD04.

ARD only do a complete TD05 turbo (with 20g wheel) http://www.ardideas.com/search.asp?s...O&keyword=td05 but Kinugawa and others sell all the various individual parts.

 

Yea thanks, was thinking of TD05 and convert the housing, think i want to stick with 16G as i've noticed a few on here who have had the 20G's and gone though a few gear boxes.

I've found a TD05 on ebay looks abit rough, http://www.ebay.co.uk/itm/SUBARU-IMP...4AAOSwZtJW-~Ln

And found Mitsubishi TD05 18G Turbo Compressor Housing and Compressor Wheel.
