Yep I have fcon v pro currently installed. Still debating what to do with the auto trans and how to beef it up a little

What you are suggesting could well make 3 times the stock torque, if not more. If you have the Transgo kit fitted you may be ok for a while, if you drive it nice.

How far off is this high flow option scotty? Thinking I need to sell my ss1 and go something capable of a bit more power

I should have some by the end of the week, or early the week after I am hoping. Then I will fit one to my car and test it out with the Link Fury running the show. Big few weeks coming up...

Get hold of the highflow built by Rick, that Scotty is using now; that thing is a monster, and seems to have no downside at all.

I can only imagine who told him that, in desperation. Hypergear have a good name, unfortunately the way you treat a customer is remembered long after the turbos have failed. We gave him many opportu

Yep I have the transgo kit installed.I think i know the company you speak of, the one you have to send them in part of your box then it gets sent back after the mods?

That would be the valve body, which you have already upgraded to some extent.

To handle more torque you need to increase the amount of clutch plates in the clutch packs by using thinner drive plates, not just bump the pressures up.

I feel the TCU reprogram is the key(2nd to stronger internals). Changing the shift duration via a transgo reprogram kit helps much less than it should due to the TCU compensating for the changes(pulling them back towards stock).

I noticed Borg Warner EFR's were mentioned earlier. This would be the ultimate option as I feel these are the best spooling turbo available on the market. Precision will make more power as they aren't limited by shaft speed but an EFR will smash it in average power/drive ability. I have one on my race car and spool is similar to stock. Transient response is excellent and below spool boost is available from idle. The design also allows for a large turbine which is great for reducing heat and back pressure. We recently installed one on an IPRASA car and it went another second faster over the previous Garrett unit with a restrictor. I'll post a vid of my WRX which runs a 6758 to show response. Mine does have anti lag but it was more for the crowd as it doesn't need it at all, it makes boost free revving.

So install wise of this long turbo on a Stagea could be achieved as the mount angle can be up to 15 degrees(advertised) due to the double oil seals they run. Mine is around 20 degrees and has no problems. I've seen the cosworth WRX run one at over 30degrees. I guess what I'm trying to say is if a kit could be made, you would be in the money.

Here are some pics of my install on the rex

Your car goes like a beast! I do like the EFRs may end up putting it in the air boxs place, i built a box around my pod filter unsure if it helps much lol, either way it looks like a good spot for a longer turbo

Cheers, not bad for a 2ltr with medium cams. The slow speed track really shows the response. I do also run a 6 speed so that helps a lot also. I love these turbos. A 7163 mixed geometry EFR would be insane on an M35.

My GTX was installed on a 15 degree tilt, I had no issues other than space. You are welcome to try and fit the EFR in the stock location, but without going to external gate housings and without the bov etc. I doubt it will fit, no matter how you tilt it. Have you seen how little room there is to work with? It makes RB26 twins look easy.

If you relocated the turbo to the airbox location it would work, but then you have issues getting a decent size exhaust through beside the engine. My 3 inch intake touches on both sides...

Small low mount twins would work, as long as you ditch the AWD, you would need to change gearboxes anyway if chasing that kind of power.

I took up the challenge of removing the GTX and putting a highflow back in, that's the smart option. :)

Anything larger isn't going to work well without spending the big bucks, auto rebuild, high stall converter, 3.5 inch exhaust, there is no way a 4 inch intake is ever going to work... I'm quite happy with 300+ on ethanol, it's the guys running 98 that will be limited by their crappy fuel. :P

      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?

      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.
