Mdx555-450 old hat?
Would the mdx555-450 be considered old hat these days?
Looking for a 450+ capable turbo to sit on a 2.1 but don't want to over spec. I see most people have a hard on for sc46 these days. What's everyone's experience and thoughts on these turbos?

No experience with MDX555-450, however I did put an SC46 on my 2.1. It lasted 3000 miles and then the plastic bearing cages gave way, SC/Blouch said warranty would not be honoured due to high EGTs. Had to pay £800 to get of fixed by Blouch, upon its return I sent it to Owen Developments to have plastic bearing cages replaced with metal ones and thicker heatsheild for bearings, that cost another £450. So personally I wouldn't go SC/Blouch again.

I also Run a Blouch,
Been re-machined by Owen Developments to fit bigger billet wheel 73HTA, Metal caged bearings, heatshield, seals replaced & rebalanced
More than enough turbo for my stock newage sti engine

very nice...I had one on my old blob sti where it made 475 odd with 20 percent methanol...that was just a 2 litre with syvecs etc...445 on just vpower...it's a very capable turbo..with my new blob sti I'm debating whether to go rotated with a gt30...it's obviously a hell of a lot more cash but any bigger standard position turbos on my blob sti are just going to be laggy I think hence the rotated idea..
I've been looking at an EFR7163 with a rotated setup, looks to be a good performing turbo with quick spool. Anyone running one of these ?

But the gains % wise will be correct,
That's V-power vs 20% Bio-Ethanol Blend

Any 450+ capable turbo on our 15+ year old design 2.0 will have a high boost threshold think 4500+
But when above that the responce from my turbo is as good as stock i would say bearing in mind it has a FMIC

currently has 10k miles on it around 400bhp
68k in total
if your going much beyond 400 i would have a plan B just in case.
but if it did let go a 2nd hand newage bottom end wouldnt really brake the bank.
