Hey all,

well ive finally decided that im gonna bolt on a turbo onto my car,

I have a front mount for the car, a standard r33 gtst turbo

and plan to get gtst ecu, and injectors.

I am also leaving the high compression pistons in, rather than getting low compression in.

Has anyone else here (im sure someone has) done this before?

If so, how did it go? any problems things i should look out for ?

ive still got to get some of the stuff for my car yet and it wont be getting done for another few weeks at least...

hey mate, firstly check the link in my sig :D

in there is a list of what you will need, also feedback frmo Dan whom did it to his r34 ;)

it's a bit more involved than just bolting on new manifold etc etc and starting the car - holes need to be bored into the block/sump for oil/water lines etc all is in that topic :rant: feel free to ask any questions in there as it will also help me :rant:

Mind sharing where you got your bits from and how much for?

good luck mate :rant:

really?

damn i was expecting to run a max of 7-9psi.

I suppose the lower boost would be better.

What sort of power do u have Dan?

1/4 mile times?

dyno?

Im thinking of getting it done at a workshop so it doesnt take me forever to get it done (whereas if i did it myself it would take forever and i would be bound to stuff something up)

You'll also need to keep the boost low, around 0.7 I believe, not that I've done this but someone on the UK site, www.skylineowners.com has.

Aitch

could you be a bit more specific about where to find that info . by .7 what psi do you mean ( i figure 10 psi ) , am i correct

Also this is a rough way of working out what pressure you can shove in your newly boosted N/A.

Going by this you can see 12psi in an RB25DET is ~ 9psi in an RB25DE, which is as far as I'd personally take my one for now, so seems quite accurate :D

Note it's a very rough way as dynamic compression is probably a more useful indicator, and this can be changed with cams.

hi mate,

if i were you, try and find a rb25det bottom end, so that you an run normal boost, you Na head will fit onto the det block which is good. also then you will need bigger injectors, either a new ecu, or try and get your old one remapped. make sure you get your turbo checked just incase it has leaks or it is blown. you will also need exhaust manifold.

if you want to use your NA motor, the most boost you can run is 6psi which isnt very high considering you have a front mount.

the best thing to do is either find a bottom end or get a half cut, less hassels and you can boost it up higher.

At least give a reason Jay...you're more creative than that!

Turbo'ing an NA is inconceivable and you'd have to be crazy to even entertain the idea. You'd need at least one spare weekend a lot of parts and too much beer...

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

      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.
