Within the next month or two I'll be looking for a power boost for my Tjet. I think I've decided against just a remap and turbo back exhaust on the vl37 I'm hoping to get above 200bhp but nothing too insane. By the time this is done all suspension, steering and brakes will be replaced and I'll have a 2.5" custom cat back fitted. Downpipe and cat will be replaced to suit turbo.

From my research i reckon I've three options, first being VL36 which seems fairly straightforward and the other two are TD 04 from WRX or GT1446 from esseese. There seems to be a lot of conflicting info about these two and i have a couple of questions i hope someone can help with.

For the 1446 I know i need a downpipe with V band coupling and some new IC piping, 380 cc injectors, sensors​ and oil and water piping.
Is it possible to use the original Tjet manifold with some sort of flange or would the manifold from the Punto evo that runs a Garrett fit ok? Also wondering if it would really be necessary to change the oil filter and housing?
Problem with this conversion is price of turbo and manifold and possible oil filter issue.
If i could use the manifold from punto Evo then it may be possible to use the Garrett 1752 which i think was fitted to some Saab's​? These can be picked up fairly cheap.

For the TD04, I'll need flange for original manifold, suitable downpipe and oil / water lines and possibly injectors, no mention that I've seen of new oil filter and housing.

Other than the TD04 being cheaper are there any pros / cons to the two set ups?

Cheers

Anyone got any thoughts of this?

TIA

Sorry Ben,

no personnal experience with that kind of wichcaft, but certainly some forumers could jump-in...

The td04 is bigger than the 1446, so you will definitely need injectors.
Where did you get the idea you need to change the oil filter housing for any of them?

You don't need new boost, map sensors...they are not faster or anything (if you have/want them that's different)

I've just installed the vl36 on mine yesterday not remapped yet.
Even the small difference in compressor wheel makes a big difference in turbo lag... so after this change i would not go to the TD04, maybe the 1446.


FIY: i have installed the Ragazzon cat-less downpipe there is no difference in noise or drone... it is just as quiet as before with the original cat.
