Made 286rwkw from 5558 on stock mani low mounted 98 fuel, boost 18psi dropping to 16. Told tuner to push it to 20-22psi but intake temps getting too hot. He said forward facing plenum will help cos it doesnt run along radiator and over exhaust cams as stock piping layout.. Its cold beside battery tray but heats up the next few centimeters.. Oh man that damn 300rwkw

water injection mate...wel done anyways.

Good work Ron!

How does it feel on the road? Does it compare to the 335kw machine you went in?

Also, who tuned it? JEM?

First impressions- L-A-G----- boy its as doughy as f**k, maybe at 60% of the stockers response up till 3500rpm, after that its coming coming then 4000rpms WHOA BANG it fkn grenades like a rocket, not much difference in seat of pants feel to the 336rwkw car, feels almost, say 90% as mad when boost is on its on! Skates and wheelspins a bit but not too mad, its awesome but the lag is just way too much, I havent driven a ' proper turboed' car so cannot judge, when I come back frm my overseas trip on Jan, u can drive it and gauge Jase, love it but the lag sucks, theres no power below 3200rpms... Is this how its suppposed to be?? 2990rpms=60kw, 3790rpms=120kw, 4720=225, 5470=260kw, 6660rpms=286rwkw

Cant upload dyno graph from iphone in the dyno results thread damn.. Anyways fullboost 18psi around 4000rpms and drops to 16psi from 5700rpms, JEM are awesome, ADAMs a top guy definitely recommend him really goes out of his way to help and explain, takes his time to go through detail by detail :)

sounds a little bit laggier than my old GTST with a 3071R on it... mine was tuned at 20 psi... see attached dyno

the different is the PT will have a lot more in it! chuck it on e85 :P

I wonder how that would compare to a standard G3 type B... For on road feel anyway.

Get the sheet up when you can, I would love to see it.

Hi guys,

I've been following this thread with quite a bit of interest and thought I'd share some info on my project.

I running an FJ20det which I swapped from my old DR30 skyline into my 1600. The previous turbo setup used a Fantasy split pulse single waste gate manifold and a twin scroll GT3071r and made 265rwkw on 22psi.

I have since built my own twin scroll manifold with twin waste gates for the 3071r. I have also built a manifold for a Vband in and out Precision 5558 which a friend of mine sources from PJs Quick Bits. I will be doing a back to back test of both these turbos on my FJ in the next few weeks and will post the results.

Cheers

Awesome that will be interesting, what fuel and engine spec? That Precision turbo should have a big edge on potential for power advantage but may need to be pushed harder than 22psi to prove it's extra lag is worth it

The engine has been rebuilt with forged piston and port work to the cylinder head. Cams are still standard. I will definitely run som proper boost through the 5558 as that's what they are made for!

I currently run two maps and I will have both tuned for each turbo set up. One for pump 98 and the other for pump 98+water injection provided by an aquamist HFS3 system. Made 295 rwkw @ 28 psi using pump 98+water injection with the 3071r. This is compared to 304 rwkw using c16. I can't speak highly enough of the water injection and once you have set up and tuned it, it's cheap as chips to run. 30 rwkw when ever you want for under a grand fitted and tuned! Can't argue with those results!

I dont think it is.

that's not why I questioned it lol, look at the power he made. 295kw. Given that he also said water injection = free 30kw, a 3071R would make 265rwkw on 18psi without hassle. Not 28psi lol.

    • 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.
