FP does an alternate compressor housing for the 3076HTA , I think its a Mitsubishi based one they use when the T04S one is too big .

I was under the impression that turbos with the S or "GT35" compressor housing fitted if you use enough spacing on the standard manifold . Isn't someone running around with a GT3582R on a std manifold RB25 ? Happy to be corrected but that's what I thought .

well after considering all the options i think i will go with: HTA 3076 .82 A/R single scroll turbine housing and the '3.25" in 2" out' compressor housing. Top mount single scroll 6 boost manifold..

Pretty sure the HKS ex housing (as used on PJ's car) on are only T25 size so amazed the small inlets can flow that power.

Angry rb: is that a gt3076 or does it have the gt35 compressor housing pn it?

If a low mount hta3076 can't be done then I will go with the high mount single scroll t3 1.01

Why doesn't forced performance offer a 1.01 ar turbine housing? Only upto .83

I think 34GeeTeeTee was saying FP don't do TS - though I am assuming you will be just getting the Garrett T3 housing, either supplied through FP or otherwise.

As a caveat - I don't know of anyone, or many who have tested the Garrett T3 TS housings so it's hard to know what flow etc to expect from them, I haven't actually seen turbine flow maps for them so I am cautious about saying what exactly to expect with them. Actually... I might have a dig and see if they have released anything.

If they do line up well, then a TS HTA3076 on an RB25 would make a complete monster of a thing - I suspect.

<edit: They don't appear to have released maps for them, bummer>

Still can't seem to get a turbine housing bigger than .83 on the fp3076 so would have to be purchased separately?

The idea of mounting onto the factory manifold is very appealing, any more info on this?

I wouldn't go bigger than .82 in single scroll - just to be clear, Garrett do different numbers for their single scroll and twin scroll T3 sizes. The single are .63, .82 and 1.06 and the twin are .61, .83 and 1.01. The .82 would be the go with single, just NORMALLY it seems that to get equivalent performance from a twin scroll housing you go up a size - but that's a sweeping assumption and will really depend on the design as well

AFAIK if you can fit a GT3582R on the standard manifold you can fit a GT3076 HTA because dimensionally they are the same .

FP have an alternative compressor housing which you can see if you go to their site . I think its based on a TC06 housing and is port shrouded . If serious email them and ask if it makes any notable difference with this housing .

Looks like only one comp cover option now.......the forced performance comp cover.

Go back to the site and look in the Lancer Evolution/Diamond star or Subaru sections and open the FP Turbos section in any of these .

You'll see pics of these turbos with FPs "84mm FAP" or flow advancement port covers - comp housings on them .

They still claim 59 pounds a minute air flow but I'd say they fit more easily in the engine bays of Evos Rexs Diamond stars and DSMs .

If it works for them I can't see any reason why it wouldn't on a Nissan RB engine . I can't see why you can't order these turbos with any GT30 turbine housing you like or without if you have your own already .

well after considering all the options i think i will go with:

HTA 3076 .82 A/R single scroll turbine housing and the '3.25" in 2" out' compressor housing.

Top mount single scroll 6 boost manifold..

Setup should be similar to yours geeteetee so hopefully make 330rwKW on pump

Sounds like quite a potent setup to me- remember 34GeeTeeTee has some good bits on his, not JUST the turbo.... good manifold(s), upgraded cams, good tune probably needed to make sure the full potential is realised. That power isn't messing around on pump gas! It should result in an awesome setup though, regardless of the final figure.

Yep I've got plazmaman too, and 6 boost and tomei type b's on their way.. Was thinking of going to jems for the tune, although haven't fully made up my mind, ..

Adam has done this combo numerous times with positive results ;)

There would be a power difference but I personally wouldn't go smaller than a HTA3582 on an RB30, remembering that the HTAs spool noticeably better than the GT, the difference between a GT3076R and a HTA3582 on a 3 litre should also not be a huge deal

      Even more fun, leave all the ADAS stuff plugged in, but in different locations, hopefully avoid any codes!   And honestly, all these new cars with their weird electronics. Pull all the electronics out Duncan, and just shove an aftermarket ECU and if needed a trans controller in, along with a PDM. Make it run basic but race car styled!

      To follow up a question from earlier too since I had the front bar off again (fking!) This is what is between the bumper and the drivers side wheel And this is the navigator side, only one thing but its a biggy! So basically....no putting coolers in the wheel arches without a lot of moving other stuff. Assuming I move to properly race prepping this car I'll take that job on and see how the computers respond to removing a whole bunch of ADAS modules

      Duncan's V37.......race car?

      By Duncan · Posted

      So I prepped the car for another track day on Wednesday (will be interesting to see coolant temps post flushing out and the larger reservoir, with a forecast of 3-14 being 20o cooler than last time I took it out). Couple of things to mention; since I am just driving the car and not taking a support vehicle, I took the rear seats out and just loaded the back up Team Trackday style. Look at all that space! To cover off removing the rear seat....it is weird (note the hybrid is probably different because it wouldn't have folding rear seats) Basically, you remove the lower seat base, very similar to a r series but it is a clip that pulls forward to release the base rather than it being bolted down. Easy Then, you need to remove the side section of the rear seat on each side. There is a 14mm head nut at the bottom of the side piece, the it slides upwards off a hook at the top to release; you also need to unhook the seatbelt from the loop at the top. Then the centre piece is weird. You need to release/fold the seats forward with the tab in the boot on each side From there, there are 2,x12mm headed bolts holding the rear of each seat to the folding bracket, under the trim between the rear seat and the boot (4x christmas tree clips there, they suck). The seat is out but you can see where the bolts attach to the bracket

      As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year.

      I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
