Is this a stock CT26?

here are some std wheels

 

yours is not std.

Could tell difference quite easily.. Awesome that saves me some money on an upgrade. Would that be much better then a CT20 though?

really depends on what comp wheel is in there.
 
power wise generally they don't make more when on an unopened gen2 with bolt on mods etc, but the ct20b is more responsive which is what you want for the std gen2 imho, as the cams choke the top end.
 
i had a TO4E hiflow, didn't get on song till 4000rpm. 

That is a T04E considering its the same as before the engine replacement. I don't have a tacho but it sounds like it kicks in around 3000rpm until 6000rpm or even less.

it would definitely start making boost well before 4000rpm, but would hit hard at 4000, boost would be a gradual increase till then.

So you reckon for what I have already a CT20 would be an improvement on my hi-flowed CT26?

my personal preference would be to have a ct20b, but i prob wouldn't bother with the hassle of swapping turbo's if i already had a hiflow'd item.
 
theoretically your hiflow should be in better overall condition being rebuilt, than an old std ct20b

Yeah true, thanks for the help again haha.
