so, turbo people, looking at getting a new turbo for the s14, as the stocker is one its way out. not thinking anything massive, got it down to a garrett GT28R or GT28RS, just wondering if anyone here has any experience with them? ill probably end up browsing the forced induction forum soon, just seeing if theres anyone here whos used either first.
cheers krish, completely forgot about dale. shall have to have a chat with him. 34 turbo sounds interesting, thinking lag could be an issue with the missing 500cc though. just looking for nice streetable power, somewhere around the 150-160rwkw mark.

Hey Dave,

If there is nothing wrong with your turbo then I would keep it fit a boost controller and go see Jeff (SpeedLab) for a remap. For around $500-$700 (my remap was around at or below the lower end of that scale but SR's need a daughter board installed which the CA's don't and the board costs around $250 by itself) your current turbo you will make around the 190rwkw mark. I have a feeling that you will be near the limit of your AFM at that point and you won't want to go to much further with your standard injectors, but you should get there.

If you want to go bigger turbo then you will be looking at at least 550cc injectors (but 740cc are the same price and they will give you more scope for improvements in the future improvements) remember that with 4 cylinders you have to go bigger with your injectors to make the same power as a 6 as there are less of them.

You will also need to a bigger AFM; once again you have choices a Z32 will support around the 320-350rwkw mark but costs anywhere from $200-$300 where as a SII RB25 AFM will support 230-240rwkw and will cost you around $50, and really even if you go for a GT2860RS you won't be making 230kw without cams.

If your still after up upgrade i would suggest the GT2860RS as a GT28R (A.K.A T28BB) is only ever so slighlty bigger than what you have on there from the factory

I would forget about the GT2871R as it's too big for what you are looking for as it will support 230-240kw without cams and 250-260kw with cams but come at the cost of response (full boost at around 3700-4000 depending on cam setup).

Anything else just ask

sorry im agreeing with the doh man, sounded like a steam train trying to take off at first and also like it stalled about 6times. crommies also terrible.

if you gonna go v8 go for elenor or gt40 :)

you guy's do realise that it's supercharged as well and that is why the idle is up and down like that.

P.S. i think it sounds absolutely TOUGH, but then i did grow up around BIG V8s.

meh i dont care if its got 2000hp it sounds terrible to me,

but ive always been a exotic loving anti v8 type of person :)

although i have developed soft spots for the 2 above v8 mentioned cars and shelby cobra's

I have a soft spot for 1967-1969 chevy camaro's... 1st series... even today they look frigging awesome...

Well you'd hate this thing then cos' it has a dirty old V8 in it ;)

lol now that sounds tuff, has tt attached much like f40s which are also tuff :)

i just dont really like the valliant style box cars pencil ruler design and engines that sound like they stalling or have metal getting chewed up inside.

but thats me feel free to disagree ya'll ;) i drive a rusty dato anyway

thanks for the advice mate. :)

fairly sure somethings not right with the current turbo, but ill wait til i pull it off the engine and have a good look at it. might just get it rebuilt and tuned.

cheers.

All this talking about ECU remapping has got me curious.

So, it's basically flashing the ECU? Everything on the outside/inside of the ECU is kept standard (eg. no chips soldered to it, etc) except the ROM data?

Would this mean, it's technically a way to get through Regency as opposed to having a Power FC or something else as your ECU?

Yes and no... you can reflash an ECU with another set of firmware which may or may not contain an updated map...

The map is EEPROM which stores a spreadsheet of air fuel ratios and other assorted timings, and is done by using a laptop in most cases, and can sometimes be done without any mods... r32 gtr ecu is reprogrammable but the 33 and 34's arent iirc. Thats one of the reasons people like to switch to aftermarket ecu's like PFC's because of the ability to change heaps of settings..

-D

and, lets face it, chicks dig live readouts on the pfc hand controller.

i dont haz pfc, oldschool gameboy with LAN cord going from gameboy to behind the dash will have to do till the funds allow :P

scandy, 3 spoke rims are made of fail............ IMHO

    • 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.
