Hey guys need to upgrade my hairdryer....oh sorry my stock turbo on my rb25.....lol

Thinking of putting a gt3040r with a 0.63 rear housing so it can be more responsive. Searched it already but no luck.

Its a 600hp dual ball bearing turbo. Want to know how responsive its is and when full boost comes on?

Who ever has this info it would be most appreciated. Basically I want to increase my present 211.8rwkw to about to 260-270rwkw. HOWEVER, response and streetability is my first and foremost goal! Dont want a snail that has great peak power but poor low-mid range.

Any help would be great? I do not wish to hi flow coz its around the same for a new turbo these days.

pfc injectors, pump, z32 etc etc.

all needed anyway

i have the HKS version of the 3040

291rwkw on 18psi with poncams

i have the 1.12 rear housing, so fairly laggy at full boost at 5000rpm

without cams you will still get boost about 4000 rpm-ish with that housing.. cant say for sure,

If you think you need 'em for the 71, your gonna need 'em in spades for the 40.

You are right though!! :)

CAn you elaborate on this GT3071R

What size ex. A/R should i use?

What is it rated at?

Do i need a custom dump? How much?

How much is this turbo cost?

Is anyone running this turbo on a RB25? If yes please state mods and power made.

PS: I will put a pfc in with the upgrade and run about a bar of boost. I will in the future place some bigger injectors and z32 afm (or maybe pfc-jetro)

Thank You In advance!!!

I'd step down to the GT3076R (HKS GT3037 56 trim) or the GT3071 as mentioned. The GT3040R is a mismatch turbo and will be too laggy for your power targets.

I'd go one back again, 250-260rwkw is smack on the peak for the GCG Unit, and it gives insane response with great top end.

For the sake of having 250-260rwkw as opposed to 260-270rwkw (which can be attained by playing with dyno numbes if you need the sheet), i know what i'd choose for the RB25.

try doing some research, you have been handed some info on a good choice.

price will depend on where you get it

custom dump pipe = YES - depends where you get it made

response - go for the 0.64

    • 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
    • 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.
