So here it goes I bought a r33 gtr series two, had some leaks here and there got it all fixed up and now runs great. So this car is pretty stock apart from the clutch and exhaust ,

So first I have a stock cat which I need to change due to restricting the rest of the system so now what brand and size should I be looking at and should it be a pretty easy home job??

Now pods are supposedly bad as well obviously be two sides to this but what type of pod should I install??

Now I want to do an initial tune as the cars running on 9 psi at the moment, so before I do that I need a ecu. Now I know there are 3 in the mix the power fc , power fc jetro and haltech platinum. Which and why ??

So now money stash is growing by this stage and saved up se extra cash I want extra hp, obvious turbos are the first thing ?? So I've read people suggest a few turbos and now I've seen people suggest the gtss the Hks 2860 I think is this correct ?? But what I don't understand is the -7 -5 at the end of each model what is this ??? As what are these supporting mods people mention ?? Is there anything else that I need to achieve power gains I'm looking at 450-500hp but I don't want to strain the at either.

Sorry for being a pain but thank you to those that take the time in helping

The -7 and the -5 are a designation of the different size of the turbos. Please dont ask which one will suit my need, as I know of at least 5 threads that cover this in detail.

Supporting mods would be

  • Bigger injectors
  • fuel pump
  • free flowing exhaust

Cat is a few bolts and time to get a hernia when cracking the old bolts. Brand? Doesnt matter, get a 3-4" body cat with matching inlets to your exhaust. 100 cell.

Pods.... You know you need two right? and you need adapters, and you know they are defectable... and that people have run 400kw on the stock air box...

ummmm.... you forgot the best ecu, link (haha, haters gonna hate) WHY?! Because I said so, jk, it allows you to run map, and eflex. It will open your world for less than the haltech and for more than the powerfc.

I went from a powerfc to link. Link doesnt give me that annoying miss on cruise.

so ill try answer quick here but there is plenty of information on the this forum all you need to do is a quick search :)

1. from what you are saying im assuming you only have a catback and have not changed the front pipes...This would be in order if you are going to change the turbos and i would suggest doing this all at once.

2. most pods are fine but do try and avoid the oil type pods and if you need to make an enclosure to keep most of the hot air away from them

3. there are endless options of ECU's available and not just those 3. I suggest you do some hard research and find the one that best suits your needs and what you will be doing with the car

4. as for the turbos again endless options are available but you will need supporting mods like the below. the ones you have mentioned vary in size depending on which one you go and will offcourse change the way they act on the car with how/when they come etc etc

- fuel pump

- injectors

- zaust as previously mentioned

as will be said in this thread a 1000 times start researching before you purchase anything and you will see much more clearly where and what you will need to get to where you want to be

Go into the forced induction thread and at the top is an RB26 dyno results. Start your research.

450-500 hp (assumed at the wheel) should be forged bottom end for reliability. You can do it with stock internals and then it just a question of how long it will last. Again, lots of opinions on this but don't underestimate the potential.

Coming from stock I suggest you really consider what are the right upgrade stages for you. Jumping from stock to that power level is a big difference. Not to mention the other items you should be doing to make sure the car can handle it (being it's age) such as replacing old bushes and arms.

Done right these cars have massive potential but I always caution folks. Remember you are talking about a power level 2x the original. So it will require the right planning and engineering (therefore $$) to make it perform right at that level.

    • 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.
