Hks Vs Gcg Wastegate Actuators

[SiR_RB]

Hey guys

I'm getting major boost drop at high rpm because I've got my standard 8psi actuators running 19psi

Are there any differences between the GCG and HKS actuators?

I got quoted about $440 for 15psi GCG actuators and about $320 or so for the HKS items

I don't need them to be adjustable just preset at 14-15psi and after a set which will hold boost the best

Thanks

How did you get quoted $440 when they are on their site @ $120ea?

What ! I sent an email enquiring about them and they quoted me $220ea not $120 !

Does it always mean it needs new acctuator ? Not that turbo just out off pig as I run 18 but makes peak power at 11 on my hg hiflow

ive seen dyno charts and people have held 20psi to redline no problems with -7's, some even higher, my wastegates are wayyy to weak for this application

[R31Nismoid]

Id like to see those graphs.

I'm yet to see one with -7s that hasn't fallen a good 2-3psi by 7500rpm.

They simply aren't big enough to slow

I'm assuming you have -7?

Didnt they come with acts? Or did you use stock nissan items?

Yeh I'm getting about 4psi drop ! Afew people only get about 2psi drop which is pretty good

They came with the turbos, have been tested and are fully open at. 8psi

They are adjustable but duno if they can be tightened up for 14psi. And I don't want to risk tightening it too much then the wastegate flat won't open all the way?

Well it seems that if you aren't specific they send the .5bar ones, guess that works for most people and means a bit more profit for the seller

So with the EBC off you are seeing 8psi?

Even though, they are adjustable for a reason. I think you should shorten the rods a bit and see what results you get from that first.

However I dont think you'll be able to tighten them up to 14psi, but you should be able to reduce that drop off a bit
