No need for it yet. I'll be doing another Det head for solid lifters and kelford 280 cams and take it up 9-9500

Nice numbers. Not bad at all.

Get yourself some jwt C2 cams, they will perform better.

Ditch the rocker arm stoppers and do the twin grove shim modification and rev to 9k+ all day long.

Also what turbine housing are you using on that t76?

Ya already considered the twin groove for the next head I kept this set up simple hence why the stock valves are still there. Not even valves seals were replace or a valve job just added springs cams and resurface?
Was also looking at the kelford 288/304s

Isn't any known use of them stateside but they have a strong following in the evo 4g63 crowd

It's a t4 .63 housing
Boost starts kicking in about 5500 so my power and is short having or left off/shift about 8k
Turbo wants more revs but can't give it to her just yet. At this power level with hooking up I should do low 10s with a 135+trap

If you look at the video you can hear the turbo lag till it gets up in the revs then it just wants to shoot up

Trust me, that turbo will love the JWT C2's. My head had stock valves, BC springs and retainers, twin groove shims, C2's, VE oil pump (your det oil pump will be fine) and was reving to 8700 no problem, took it to 9100 several times just to say i broke 9k and had no issues. Power was still climbing with the C2's and T67 with a t3 .82. made 486whp at only 18psi and still climbing at 8700 rev limiter.

The C2's will absolutely love that turbo, run them straight up, no gears. You will see a huge difference.
