Default Turbo choice.......

So i think im in the market to buy a MD321T.......

where is the best best to buy one of these from?
its going on a 2 litre so im guessing the smaller intake is probably better for this also

any other turbo choice people would consider instead of this one?

smallest one they do is the efr6258 which they rate to 45,0 but in the real world will probably do right around 400

All depends on budget,

Proper Billet 20g around £6/700
Sc42 around £1600

Or custom setup unsure on cost but wouldn't expect change From £2000

Dont forget your harvey up pipe as well for the free spool gain

I've got an sc46 on mine now and love it. Had a sc38 on before and there isn't much in the lag. Especially if you have the supporting mods on a 2 litre

I'd recommend a Harvey trick up pipe with a bigger turbo. It all helps

Not correct, depends on set up, but now my avcs is working, I feel it start to spool at 3200, I was at blyton over weekend and honestly I really didn't need to knock it down to 2nd on tight corners, I could easier be on boost coming out of corners in 3rd, it's an awesome point to point turbo, I'd say 450 is easily achieved on meth.
Need to get mine on dyno again and see what's what.

Have you got a graph of your 46 on the 2.0? As 46 was made for a 2.5

Both good turbos, but the billet version of the md is mdx321t which is the one I'd get, not the non billet version, md seem to made slightly more power on vpower than sc42 too so either will be fine.
Depends on cost really

What turbo are you running? I was expecting it to be worse comparing to my old sc38. There isn't much in it really. Meth map next I think lol
