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. :thumbsup:

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!!!!

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:

Adam, please don't be gay. Plumbed back external gates are for girls :D

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.

and for those who dont like getting pineappled by the boys in blue

exactly

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?

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.

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 :happy:

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 :blush:

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.

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.

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.

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.

    • Have a look at that (shitty) pic I posted. You can see AN -4 braided line coming to a -4 to 1/8 BSPT adapter, into a 1/8 BSPT T piece. The Haltech pressure sender is screwed into the long arm of the sender and factory sender (pre your pic) into the T side. You can also see the cable tie holding the whole contraption in place. Is it better than mounting the sender direct to your engine fitting......yes because it removes that vibration as the engine revs out 50 times every lap and that factory sender is pretty big. Is it necessary for you......well I've got no idea, I just don't like something important failing twice so over-engineer it to the moon!
    • Yup. You can get creative and make a sort of "bracket" with cable ties. Put 2 around the sender with a third passing underneath them strapped down against the sender. Then that third one is able to be passed through some hole at right angles to the orientation of the sender. Or some variation on the theme. Yes.... ummm, with caveats? I mean, the sender is BSP and you would likely have AN stuff on the hose, so yes, there would be the adapter you mention. But the block end will either be 1/8 NPT if that thread is still OK in there, or you can drill and tap it out to 1/4 BSP or NPT and use appropriate adapter there. As it stands, your mention of 1/8 BSPT male seems... wrong for the 1/8 NPT female it has to go into. The hose will be better, because even with the bush, the mass of the sender will be "hanging" off a hard threaded connection and will add some stress/strain to that. It might fail in the future. The hose eliminates almost all such risk - but adds in several more threaded connections to leak from! It really should be tapered, but it looks very long in that photo with no taper visible. If you have it in hand you should be able to see if it tapered or not. There technically is no possibility of a mechanical seal with a parallel male in a parallel female, so it is hard to believe that it is parallel male, but weirder things have happened. Maybe it's meant to seat on some surface when screwed in on the original installation? Anyway, at that thread size, parallel in parallel, with tape and goop, will seal just fine.
    • How do you propose I cable tie this: To something securely? Is it really just a case of finding a couple of holes and ziptying it there so it never goes flying or starts dangling around, more or less? Then run a 1/8 BSP Female to [hose adapter of choice?/AN?] and then the opposing fitting at the bush-into-oil-block end? being the hose-into-realistically likely a 1/8 BSPT male) Is this going to provide any real benefit over using a stainless/steel 1/4 to 1/8 BSPT reducing bush? I am making the assumption the OEM sender is BSPT not BSPP/BSP
    • I fashioned a ramp out of a couple of pieces of 140x35 lumber, to get the bumper up slightly, and then one of these is what I use
    • I wouldn't worry about dissimilar metal corrosion, should you just buy/make a steel replacement. There will be thread tape and sealant compound between the metals. The few little spots where they touch each other will be deep inside the joint, unable to get wet. And the alloy block is much much larger than a small steel fitting, so there is plenty of "sacrificial" capacity there. Any bush you put in there will be dissimilar anyway. Either steel or brass. Maybe stainless. All of them are different to the other parts in the chain. But what I said above still applies.
