External Wastegate On Rb26dett?

[_K1NGTR_]

like the topic sais im a huge fan of EXTERNAL WASTEGATES my boss has alot of evo's and he has one on each of them and i think they are the best is there anyway to put them on my GTR? do i need two im not good with this stuff so i thought id get some advice got standard turbos gon go N1s soonish but yea i want that scream of the EXTERNAL and can i hide it well? thanx guys

You can do it. but the reason is why? just for the sound? Putting an external gate on a pair or N1's are not needed (can achieve 400kw in some cases) but they are only need if you are using high power low mounts. Just for arguments sake a pair of 2860's running 25psi obviously you dont need to go external gate but it will help control boost alot better. External gates are usually used for big single turbos or twins making over 500, 600hp + kinda thing..In your case unless you are going for huge horse power you don't need an external gate. If the gate is big enough say 50mm upwards you might get away with 1 but generally if you use 2 turbos you use 2 wastages and you can mount them anywhere you like if you have enough $$$.

There is no room too fit two external wastegates with a low mount TT setup.

I mean, you probably could if you fabricated absolutely everything from new manifolds, intake, oil/water, dumps etc etc etc.

Maybe fit one big gate...

Silly idea and expense end of the day just for a sound. Not to mention you'd never get away with it here in Vic... i didn't 4 years ago, times are a lot tougher.

External gate = single or highmount twins only

You can make over 450rwkw from internal gates, so no drama there

If you just after the noise then just add some screamer pipes to the dumps and problem solved! Alot less $$$ aswell.

Ye but internal gate screamers sound nothing like a true external gate, not even close... and often have issue with sealing at idle so you get exhaust leaks and so on

A wet fart best describes internal gate screamers, and no-one likes having one of those

[johnbarry88]

pure and simple we have given you the facts of why an why not, so its up to you to make the decision on what you want to do...just know if you get caught with a screamer you'll get f*cked over..

nawww i really wanted one lol with the nismo Exhaust that i installed the aggressiveness of my car is gone just another question i have a hks SSQ and a HKS that makes a standard air noise and the SSQ shits me to hell if i put stock GTR bov's on will the Car make a nice noise cuz i wouldn't mind hearing a little dose does anyone know how to make a GTR dose other than re locate the AFM into the cooler piping or after market computer that disables the AFM?

Like if i blocked both my BOV's off or change my cooler i duno just asking

Lancers are a very different beast being an inline 4 , they are a lot easier to package an external gate into than a twin parallel turbo inline 6 . Actually there are some really good twin scroll twin integral gate turbos available for 4G63's - but thats another story .

IMO you would go backwards with one wastegate controlling two turbos because you lose the pulse seperation effect of two turbos on their own individual exhaust manifolds . Once you link them together you may as well have a 6 into 1 manifold and a single scroll single turbo .

You call but I would have effective twins on an RB26 and call it a day . Sounds can be emotive but I'll take function over flamboyance every time .

mate all your questions have been asked, just search some VL-terms like:

-dose

-blocked bov

-cooler noise

etc etc

i heard about 6-7 years back you could buy a device that you attach to your gearbox so when you change gear it makes the BOV sound for non turbo cars, maybe by now they the same thing for gates, then you wouldnt have to spend heaps of coin, and maybe lose power????
