Is this something that has ever been done, with something like a 20G etc ?

Yes Matt.subaru4you make a rotated standard fit turbo uppipe/downpipe so you can have a 20G in rotated position

i thought this was only done because the turbos are to big to fit in standard position

Ive done it on my rally car (vf34) the idea is to keep the airflow (inlet/exhauts to turbo and exit) in nice straight runs, the less you try and turn the air through tight bends the better.

That's good news as its something I've been thinking about lately. Yes usually people only go rotated to allow for bigger turbo fitment but I'm thinking more along the lines of keeping the inlet straighter and cooler. With a standard fit the inlet runs under the manifold and must get very hot, with a rotated setup I could keep the inlet away from such temps and bends.

Any ideas on price chaps or links ?

Not cheap

Superb thread. Ive saw some classics with rotated 20g's and always wondered if there was a kit. The engine bay looks so much neater.

Is spool noticeably quicker?

Found it.

Looks like £500 plus the vat (why do companies do that, just put the total price please)

Then all current pipework, feeds and drains need to be addressed as in the rotated position very few will fit. You keeping the maf?

Don't run a MAF buddy.

Obviously there would be some work involved to make it work.

Simon had it fitted to his car with an MD321T, worked pretty well from what he said

Matty not sure if will worth this to do,you will not gain more bhp etc.

Yes will look better,but for this price I would send your turbo and get billet,this will be better idea and with this you should gain like bhp and spool

I made a thread asking the very same question awhile back when I got my 20g and the outcome was not really worth when comparing costs to gains to be made.

I think spool is notably sooner, yes.

It's one of the main reasons for doing it (aside from if you were to have a too physically large a turbo to fit in std position, obviously).

I've heard (for large 500+ rotated turbos at least) that anything up to 1000rpm can be gained in spool-up(?!?!). So don't know what gains in spool-up you can expect for a relatively small 400+bhp turbo - I expect it's proportional(?)


But I stand to be put right on the spooling aspect...
