Results Of Gt3076r With .63 Housing And Ex Gate

[Dale FZ1]

There's no doubting it's a cracking result, though I'd be interested to see it run on the rollers again after that screamer is given the heave-ho.

Every time I see an EW setup and results of boost control, it's pretty clear that the effort and expense is well justified. It's a real bugger that you had to go away from the original plan, but if it won't fit, it won't fit. Grafting a pipe onto the housing obviously works, just doesn't look that elegant and makes it difficult to swap housings if the need/want arises.

Couple of comments about the DE+T spec: I've got a set of those 25DE pistons, not a bad thing but they do have sharp edges around the valve cutouts. Can be knock-inducers so keep that in mind. Also the DE block does not have under piston oil squirters. The oil jets take temps out of your pistons, so be aware if you intend taking this thing to a track and running consistent high rpm/load.

Given you're powering a GTS4, this engine/turbo spec would be quite satisfying on the street, vs a GTR which would work in a different rev range.

Ahh so another DE+T conversion.

You know if I had a RB25DET and I blew the motor, I'd grab a DE and use that instead. Or even put DE pistons in a DET block to retain the oil squirters as Dale has mentioned.

Wicked build nonetheless - I can imagine having that much compression, it would build boost FAST, especially running such a small rear housing. The reason my power levels are so close with a Turbo compression motor is because I run water methanol injection - and this means I can run a lot more timing.

Imaging WMI on the DE motor... Would be insane.. Problem is, with such high compression, if the kit died it wouldn't take that long to kill the motor. But, I would think the DE motors are just as strong, if not stronger than the Turbo motors. This is just a guess but would the pistons have more meat on them, or is the gudgen pin height just a little lower?

I love this thread - Thanks for sharing it with us mate. You're a champion.

this is great to see a setup basically what i was looking at so i have an idea on what it will do, thats more power than i was looking for so i am excited to get the 3076 all up and going now onto my car!!!!

[BTM]

the screamer is ridiculous, way too loud, so I will plumb that back in.

Stao, it will be an interesting comparison, your prototype looks really good.

Thanks for the interesting info Dale. I only took this to winton when it was non turbo, but I have been wanting to get to some track days, so the higher piston temps is something I will have to think about.

Jono your very welcome, thanks for posting up you dyno, I will have to get the torque graph off Sam. interms of boost building fast, it is under a second delay from foot down to boost and have always enjoyed that about the car as so far it has been a 98% daily.

thought i'd crawl under the car and show you guys the screamer:

Where did you get the bell mouth insert for the intake? you mentioned the HKS core....was it a broken 3037-S that you had rebuilt with a Garrett turbine housing?

Yes the sound has grown on me, but i have spent that much time and money on it that I would hate to have to take it all back to standard and jump through all the hoops the cops make me do just for the sake of a few db of loudness. as long as I can make it still have the same power plumbed back and a bit of gate noise I will be happy.

see this is the thing that I dont get. I purchased it brand new fully assembled from a Garrett distributor as a gt3076r with .60 inlet and .63 exhaust. but the core says 3037s, I thought that was a HKS model or core or something they did?

and the bell mouth insert came with the larger Garrett anti surge front housing, but we havent needed to use it as yet as there is no issues with surge.

[zebra]

They are the same turbo bar the turbine housing and bell mouth.

So that would explain the 3037 CHRA #

I guess it has just come off the same line the HKS turbos do

[l0WRB]

should try the bell mouth insert, you will get a nice loud induction whistle as it comes onto boost. similar to hks t51r or t04z

[Lithium]

You get that without it too?

[l0WRB]

you mean with the normal port shroud? works in the same fashion, i wasnt sure if he had the port shroud version or not..

[zebra]

The bell mouth only fits the port shrouded comp covers

all 3076s have 3037 written on the badge, its their code under the old garrett naming system before they switched to using compressor diameter for the second 2 numbers. there was a thread a while back with details of where to get bell mouth inserts iirc

Package drives so smoothly... Looking forward to doing a 3076 twin scroll on my R32 GTS4 RB25DE+T... Might even try E85 with it

Adam - I'd be interested in seeing the difference with / without the insert and gate plumbed back... Let me know when you're ready and we'll work something out

[Don Dada]

That's a rather impressing result as i along with many others here would have thought the .63 would have been incapable of these sort of numbers without special fuel or water/meth injection based on "mafia's" results some time back.

What makes it even more strange is that u would think the higher comp motor would be more prone to det with the small turbine but yet u pull it off with knk no more than 20

This shows us that the true Garrett .63 is capable of nice numbers and its a shame that we dont have more results with that turbine as it seems to be the trend now just to go for the larger .82

Happy to do it Sam, i'm interested aswell, give me a little time to get some cash back up and we'll chat, i really want to avoid loosing any power/torque by plumbing it back in.

I managed to open up the hole on the heatsheild to fit the new pod you gave me(see below), looks good imo and at least thats 1 less thing to be defected for. will do the other heatsheild to hide turbo over the weekend.

If you gate next to a cop you deserve to be canary'd lol.

There is definitely an argument for street cars to have external gates plumbed back in, but seriously, how could you happily remove the glorious sound Adam's car is making.

I completely understand the argument. It's an experience I've been through before. But I can only imagine how your car currently sounds, and feel it would be a loss to other road users to lose that external gate noise

I'm going to have to learn to drive sensibly again once my external gate in on my car. I tend to use it as a self control mechanism so I don't drive like a dickhead haha.

[WYTSKY]

lol you make a valid point ie, if you gate next to a cop... but in this case its more if he is in the surrounding suburb.... havent had a chance to get a video of the car, but will do my best for this weekend.
