21u highflowed onto a 34 neo engine

[SoulScene]

Basically my op6 r34 turbo is dead, for a quick fix will the 21u r33 turbo (highflowed) as i can't afford the gtx3076 just yet but need the car on the road. As far as I'm aware it'll bolt on, and being highflowed would assume it'd be same/better than a standard op6?

It will be much better than a standard op6. You will need to have your car tuned if u want anything decent out of it. Otherwise you can run it as is at say 10 psi untuned and it will be ok and perform roughly about the same as your op6.

Will be better than the standard op6

Recently went from op6 highflow to 21u highflow on r34, hoping to achieve better response, haven't started car yet so can't really comment since I'm getting a whole lot of other stuff done to it too. but I hope it'll achieve good response and make around 260rwkw region

Mine made 260 on 98 and over 300 on e85.

Awesome thanks guys, just after a quick fix for now so the car is driveable so 10psi will be fine.

Gearbox needed rebuilding, turbo went and then got rear ended to top it all off, all in 14 days. So unfortunately the turbo got the quick/cheaper fix for now

How did you go with the retune man? Was the op6 really laggy?

Will find out soon, still busy finishing off some of the work on the car

I've had 21U highflow from precision, OP6 from GCG and OP6 from hypergear throughout the few skylines I've had and I preferred the 21u.

Managed almost 280rwkw on 20psi from the OP6 hypergear but the OP6 highflow doesn't really see full boost until 4000rpm

It'll hit full boost slightly earlier on the 21U. But I think the biggest difference is partial throttle response, where it matters the most in everyday driving.

Seeing that Hypergear is getting some good results from the 21U i thought I'd swap the rear housing over. Will report back once it's ready to go

Yeah that sounds about right, I managed to get 397kw on a hypergear op6 highflow..minor spike to 22 psi then drops down to 20 psi. Looks like I will be getting a 21u housing machined up. Thanks for the reply and good luck with your car!!

Any news on this? How did it go with the 21U?

Wow that's a crazy good result! E85 I'm guessing?

So did you get the 21U turbine housing? And how laggy was the OP6?

Is that a typo? 397kw? did you mean 297kw?

 

Cause damn, 397kw on a op6 higflow on 98 is wizardry.
