Why are we being brought into this thread about how to spec and engine to suit a T4?
It could have been an interesting and productive thread for once!
Pretty much everytime you post on a thread like this it's to try to stir shit or score a few points.
We didn't build any of the engines in question here so i fail to see what we have to do with it?
It's just pathetic steve, you need to build a bridge and get over it lol.

I've never known to feel a difference on a low comp car vs std comp...Euan's old 550bhp, his was 6.2:1 and he swore it drove as well as it did off boost as it did when it was standard
Same as the old "oh huge intercoolers an it'll be laggy/unresponsive"
I never noticed any difference whatesoever when I doubled the size of my apexi intercooler on my 200sx...
Think people jus mump their gums for the sake of it half the time when 9 times out of 10 they've never tested their theory's!

I only said it was the first time Doug had used the car after being set up.
I said nothing else.

I can't wait to get my T4 saff back up to MSD, the standard T4 has been replaced with a roller-bearing maram shafted unit, so I am hoping the claims of the roller bearings making it as responsive as a T34 are true

Slightly lowered cr, probably around 7.5:1 I like bd16/14 combo, stu likes bd16/15
Good spec head not mad on port sizes, 83s lots of boost and a good map
They work really well.
I'd still choose a T4 over almost any other YB turbo. I just love the way they make boost

obviously timing makes or breaks these engines making it aweful or IMO brilliant.I'm with you james, t4s are awesome, I love the way they do business with the above spec

on the dyno it was pulling hard at 3500, gave 540bhp at 7500 and 510bhp at 8000 with a smooth flat torque curve. awesome engine, cant wait for it to be done so we can check the mapping in the car.
some people will look at the graph and say the torque is low, but everybody gets used to these rolling road figures with massive boost, gavs had 32psi everywhere
