Best turbo for B12

[Swirl]

Ok so just thinking out loud, been reading about td04 turbos, is this the turbo of choice for you guys, or are there any other common turbos that should be considered, I'm thinking for ease of purchase of manifold etc

Well..... mine is the best turbo for a b22..... why , You ask ?...... because  I said so .

I'm using a TD04 - the saab one which is slightly bigger than the subaru and mitsubishi evo one.  It spools up very quickly and I reckon its perfect for a road bike.  Would use bigger if I wanted a dedicated top speed machine.

If you prefer Garrett, take  a GT2860R ar .64 for street

td 04 turbos all use the same exhaust side wheel . The turbine housings( exhaust ) vary on size and shape . Volvo are probably most compact . Compressor wheels vary and so do the housings . Td04 13 (basic scooby )mate uses loads of them to turbo mx5 cars and they do 250hp at the wheels on the dyno . Get an old one off the bay then purchase a new core for £150 then swap over off you go .

from my previous SAAB tuning days - the 9000 TD04 has a 6cm housing, the 9-5 or 9-3 use a 5cm housing - both are 15T - a brilliant upgrade is to fit a compressor wheel from the garrett GT28 - best to use the 9000 6cm housing for this, the GT28 outperforms an 18T compressor upgrade - and although you may get a tad more top end using a 19T compressor, the 19T is difficult to tune where as the garrett 28 compressor is very easy - I did not observe any noticeable lag when increasing the compressor to the GT28 - also where using the mitsubishi compressors (18 or 19T) you needed to run 1.4+ bar where as the GT28 made good flow nearer 1.2bar

the GT25 turbo's from the same cars are also good, spool is a bit quicker than the TD04, only losing out to the TD04 at the top end
