Adaptor To Use Ex Gate On Stock Manifold

[Don Dada]

What do u guys think of this thingy to mount a Gt3076/GT3037 on the stock manifold?

Couple of points to note....

1) No internal WG so no f@&kin around with actuators and dump pipes for proper boost control.

2) No excessive heat in the engine room from using a ss high mount as the original heat shield can be reused.

3) No headaches to pull off the ss to repair when they crack

4) No need for a spacer to clear the compressor from touching on the manifold.

5) Everything just bolts up with new gaskets

6) Cheaper

7) Did i mention it was cheaper?

And the cons.....

1) Will it clear the strut tower with added 2.5" or so added to the side?

Does any one have pics with the Gt3076 mounted on the stock ex manifold using either this or the normal flat spacer???

What do u guys think??

Thanks.

is this a cheap chinese no-brander ebay part or is it a proven HKS / Trust / Greddy item?

im guessing a cheap chinese ebay no brander part so its probably not proven / useful

i mean, the exhaust gas is forced out one way and full throttle then a 90deg port is opened

i dont how other gates are setup but im certain they aren't 90deg bends ?

i agree with external gate for better control and stability sure

but if you goto the effort and $ of external gate, you should really do it properly

ghetto external gate setups = not my preference

you get what you pay for basically

Is is a ebay part and i have no evidence what so ever of its results.... kinda why i asked the question in the first place

Anyway i had the same concern with the ex gas venting at a 90* angle but i guess its ok since it vents where all the ports has already merged and in a common chamber.

The other ss ones that alot of ppl seem to be using vents from a common chamber also, but at 180*.... ie. in the total opposite direction of the air flow

As i said i have seen no results but it just seem as a very convenient option instead of using a high mount or welding a pipe for the ex gate off the stock manifold.

i think the spacer i used was 10-15mm so this is either 40-45mm longer

I personally don't think there is alot of room down there

maybe they are not for skylines but some other car that has more room

[Don Dada]

Its in a C35 Laurel chassis sooo... i do believe i have more space than a R33 Gtst chassis

This is the only pics i have thats kinda showing the area

you get what you pay for only very rarely cheap obsolete versions of the genuine will work out my advice spend the extra dollars

[Don Dada]

Its nothing but two T3 flanges connected by a piece of hollow section with a 38mm wastegate flange on one side...... can be fabricated pretty easily if u ask me...... the mechanics of it however is a bit questionable...

And spend the extra dollars on what?????

[paulr33]

he is saying (as am i) that its probably a junker product

if you are up to trial fitting and mechanically minded etc then go for it

fit it at home and set it all up and away you go

if the part is ass you remove it and go to how it was

if you arent and you have to pay a workshop to do it then its probably wasted $ as the part could be ass

Do you already have the turbo? if so just pull off the intercoller piping in the engine bay, measure from the face of the flange on the exhaust to the strut tower then measure from the face of the flange on the turbo to the furthest side of the comp cover, add 2.5" and see where you are at, then post it up here coz i would like to know as well.

As for it being a cheap chinese part some are good some are bad, this one looks pretty simple with not a lot that could go wrong, whilst it is better to get name brand stuff sometimes little things like this sometimes have no difference from the name brand stuff.

I also dont believe that the 90o venting will make much of a difference, all a wastegate does it relieve pressure before it gets to the exhaust housing.

Don't have the turbo but i'll see if i can get some dimensions off Garrett site.

This looks sweet though...

That is neat, i had one a bit different, sold it a while ago as i decided to stay internally gated, here is a pic:

Could use one of these

I went thru the exact same dilemma when I installed the HX35 on my RB30det. and I looked at these but was stopped by the sheer size of the turbo. there was not enough room without the turbo touching the strut tower.

also I was worried about it cracking due to sheer weight.

I ended up using a 20 mm spacer to get the clearance I needed and then going and external gate mounted on the manifold from a section of steam pipe the same as worp3d's but joined at the collector on the top. I ended up with PERFECT boost control and decent clearance. I fabbed up the lot myself and it looks reasonable.

what foolboost has posted is the way to go. but it would require a lot of custom work making it to expensive to justify as by the time you had it done you could have bought yourself a 6boost manifold.

HAVE A LOOK HERE FOR MY TREAD WITH DETAILS AND PHOTOS

Since the turbo is with out actuator bracket its got abit more room. should be a very useful bit of gear for high boost application.

Is this a something u made or is it pre-fabed?

[r33_racer]

I spaced it out 15mm. Welded w/g outlet to the exhaust housing and bolted it upto that. GT30 lowmount with ext gate now. Works well.

I had to use an adaptor like this to fit a gt35/40r to rb25/30 in r32. The compressor housing was touching the manifold so a spacer was needed and it was a good place to fit wastegate fitting.

If i used a straight spacer, the turbo would hit the chassisrail. as it sits now, i have about 20mm clearance

BETTER

[Don Dada]

Yeh i figured the one with the angle will allow for more clearance as seen here

The one i pictured above and all others i have seen that is recommended for the Rb however doesn't seem like it would work without modification.

The holes on both sides are threaded so i guess it was designed to work with studs on either side which will be fine for the turbo side but impossible to bolt to the manifold because even if the thread is drilled out the hole is sooo close to the wall it would not allow for a stud to fit especially where the wastegate flange sits.

Someone on another forum went through this and was left to weld the adapter directly to the manifold

The one "Foolboost" posted however seems like a better option although i think the wastegate flange/type might be a little too big....44mm right?

Anyone know where i can get that type of adaptor???

Thanks.

[Don Dada]

aaaaah my thoughts exactly......

Was writing when u posted.

And again, where can i one of those?
