hey every one

i have been looking a while now and would like some opinions.

i am looking for an external wastegate to suit the setup im putting together on my r33 atm.

setup consists of:

standard rb25 with replaced head gasket and stud kit.

6 boost external gate manifold,

gt3082 with a .63 rear housing,

plazmaman plenum,

wolf v500 (afm removed),

750 cc injectors (may go e85 later on)

surge tank with 044,

exhaust, intake and fmic as always lol,

a turbosmartkompact plumback Bov.

i think they are all the mods related to the topic.

i am pretty keen on the new comp gate 40mm wastegate from turbosmart, would it be suitable with my setup or if not what should i look for

i am planning on having it run at 18 psi.

what are your thoughts?

Not the best choice of rear housing IMO, doesnt really justfiy/support the expense of aftermarket manifolds/intakes etc as the turbo is going to be choked to the heavens

As for gate sizing, read the FI Guide ;)

Tial MVR.

Cheap, reliable, well engieered, v-banded for easy installation.

Did I mention they are cheap?

Confuses me why people spend $500-600 on turbosmart gates, they are good, but wayyy too expensive! Especially when there's cheaper alternatives for half the price that are just as good!

    • I don't know any details, but I really wouldn't be surprised if they do it as a LHD only version, at least initially.
    • Thanks for the replies everyone. Definitely a coolant push. Oil catch can is empty and always has been. As the engine is out now I'll be having a good look over things. I do have some detonation on the piston tops from a trigger issue back about 5 years ago. I felt it and shut off then bought a new ecu and changed the trigger. Never been an issue since. It never hurt the power, its made almost 80hp more since that incident but I will pull the bearing caps to take a look. If the bearings are damaged I will do a bottom end refresh. Head is being re conditioned at the moment and the block will be cleaned and checked to ensure it's flat. I'll go with a kameari gasket and see how it ends up. The other thing I'm not super keen on is the cylinder colours. I suspect this is from the inlet manifold. The plan will be to put it back together, retune and then stick a plazmaman billet inlet on it and retune. I'm happy with the power, if it makes a little more, then great, but I would rather just make everything more efficient at this stage.
    • Maybe they'll look to do a bunch of presales to help inject some cash fast for their financial issues...
    • Does it also misfire equally when revving?   Josh is very correct in what you should do. The coilpack harness wiring loom itself is a known problem due to its age and the number of heat cycles it has gone through. Throwing parts at a vehicle to diagnose the issue isn't a smart or good way to do it. Secondly, you may have a bad coil pack, you pop replacements in, they fix that issue, but messing with the harness breaks it, so the issue persists. So now you think "well it wasn't the coil packs" and have to continue chasing your tail, potentially swapping back in your shit coil packs and returning the good ones (yes, I've seen people do this because 'it wasn't the problem' and they want to save money). And suddenly, you've got two issues with the same symptoms...   Diagnose, don't use the spare parts shotgun.
    • Well the articals keep saying a Q50s (Skyline in Japan) with a new Manual gearbox. I like the talk about the new looks with the round tail lights. I hope they bring back the retro look like they did with the Z
