Adjustable Wastegate

[1400r]

Ive got a 2530 on my fairly stock 32 and it has a hks adjustable wastegate on it I cant seem to get it to run less or stay on .8 or .9 bar I have it wound out (its almost loose) as far as possible yet it still runs .9 bar and feels a bit laggy.

Are they made to run .85 bar( or 12psi) standard? I read this once in HPI and I guess it would explain why I cant get it to run less boost.

How far is your done up and what boost are you running?

I have mine so tight and im running 20psi. I dont know whether its a good thing or a bad thing but it works.

that's a rather large turbo for an RB20 isn't it?

I doubt you'd get stock turbo like performance in terms of lag.

and I always thought the HKS adjustable wastegate rods were set to 1 bar (14.5psi) at the loosest setting.

2530 large turbo? eh? they are pretty small mate. they are amongst the smallest aftermarket turbo you can get (obviously except 2510 and SS). hell GTR's use 2 of them and are only 2.6litre...

2530 on a 2 litre engine is a nice combo. not very laggy at all.

I put my stock wastegate on last night and the car seems yeaps better spools up alot better and doesnt hesitate at .5 bar like it did with the hks adjustable one I might get it tested at a turbo place see if they can fix it. Im happy running stock boost for awhile anyway till I get a remap and inj. Thanks guys

hmm sounds like my issue. ive got an adjustable hks one also.. its got the bolt in the middle of the rod.. which way do i turn it to tighten / loosen it ?? also if i play with the wastegate do i need to get her dynod again if i dont increase the boost at all ??

if you loosened it too much it may be opening earlier and hence more laggy, I would have though 0.8Bar would be there minimum boost pressure (much like the T518Z I have 0.8Bar minimum)

im only running ~13psi.. ive got my ebc hooked in and it works alright.. but i think the wastegate is set at 18psi which is maybe the problem ??

how do i go about making her looser ?

heres a pic...

???

does mine look tight or loose ?

[justin911]

ok people... lets just say things that shouldnt of been touched where touched....not important whos at fault..

can someone with a hks actuator take a pic or something please so i can see how big the stupid rod thing is meant to be ? ive tried a few times but now the ebc isnt as happy anymore
