Hello

i have an r33 gtst and i plan on going high mount turbo setup,

a few questions i wanna ask before going threw with this.

Is there a way without using a forward facing plenum?

Will the power steering ressy will need to be relocated/were?

Also what other upgrades will need to be done to support mt gt35/40 and 38mm wastegate?

the main reason im doing this is about 1 year ago i bought the upgrades

not knowing the cost of labour and so for a project i wanna put it all in.

Just looking at it i will cut abit of the piping out on the intercoooler and spark plugs/coilpacks will be easy to replace.

I see there are threads on forward facing plenum installs which is good, also to the people who have done it have they used the chinese manifolds and are they any good?

Thanks Alex

I just wanted to ask this question before starting, ill be posting pics if anyone is interested.

The best thing to do would be to read some threads.

You will probably sit there for weeks reading discussions about how people did their setup and lots of random crap but by the end of it you will have a really solid understanding of what you need and whats going on.

Half the questions you have are fairly common knowledge and arent of concern during the build. Im not being a prick when I say this, but do yourself the favour and read read read. You will NOT regret it in the long run.

Definitely agree with all of the above. All of the information you need is in these forums and you really need to find it, read it, and understand why it is the way it is.

That will be the only way to make the right decisions which will give you the best outcomes for your particular goals.

If you just ask people for the answers you will be putting together a sub optimal package.

Oh okay, all advice is good and very appreicieted.

I will be doing the basic upgrades this week.

Intercooler, walbro fuel pump, exhaust, coil packs and spark.

If I just start off with a boost controller on that is 12psi too much for stock turbo and injectors?

Every R33 is different, some will start to go backwards after 10psi some will go to 14.

You will feel as you increase the boost a pound at a time that it will either gain power or lose lots of power.

12psi is a safe maximum if you dont want the turbo to die too quickly, but use the method i mentioned above to see if you can even get to 12... My R33 went backwards in power above 10psi, so I left it at 9.

As stated by the others, unless you do the reading yourself you wont have a real understanding of whats happening because we will be just telling you yeah do this and yeah do that.. If you read it yourself through all the threads we already have you will form your own understanding of how to do it and what works. That way you can build the car once with no hiccups.

Don't do coil packs unless your having issues. Standard ones are fine. Save your money. Also don't bother with iridiums. Bcpr6es

If you're keen to retain the standard plenum, then this is an option.

This is a photo of my setup - High mount Kinugawa t67 turbo with a return flow intercooler + supporting mods. I had to relocate the afm into the intercooler piping though.

Okay,

Today I got my exhaust fitted up, new spark, new coil packs, upgraded the fuel pump to the walbro gss342 or whatever it's called.

Tomorrow I'll get the intercooler done and put the boost controller in and see what I can get out of it.

That pic help a lot mate thanks. I've been looking at the high mount setups and a lot of people have done individually different.

Is there a way without using a forward facing plenum?

Yes, plenty have done it. Just loop the piping around...

Will the power steering ressy will need to be relocated/were?

Yes sometimes, just moved slightly. Nothing major

Also what other upgrades will need to be done to support mt gt35/40 and 38mm wastegate?

A GT35 will push 400rwkw - so you'll need around $20,000

You need to factor in a motor rebuilda at some point - $8000

Clutch - 1400

Diff - 1500

Injectors - 900

ECU - 900-2500 (AFM or not $400)

Coilpacks - 600

Cooler & piping - 800

Manifold / turbo / dump / gate - $4000-$4500

Decent Fuel setup (no, your walbro does not count) - $800

Then throw in the labour to do it all - $3000

That's actually over 20k already not counting any other issues/failures and regular servicing & maintenance.

So remove whatever cost from that you've already purchased, and you have a reasonably idea of where you are at

also to the people who have done it have they used the chinese manifolds and are they any good?

Don't even bother. You don't put a $2000 turbo onto a car, that makes 400rwkw - to put a $400 manifold on there.

Okay, I don't want the 400kw, so what turbo would be good for 240kw to 280kw that's responsive?

Thanks for the input too :)

Heaps of options for that, high flow, Kando, hyper gear, Garrett 3071 or 3076 etc etc..... Have a look in the RB25 dyno results thread and ull see the main players over and over and you can pick the one to suit you :)

The hardware required for 240-280 compared to 400 is huge. Check dyno sheets as suggested.

Personally I would go hypergear ss1pu for that level.

Well you are in luck, 240-280rwkw is well covered on this forum.

Please use the search function, read the dyno threads etc etc.

Thanks.

    • You Gregged a whole racetrack!?
    • Look for broken wire or bad connector at the motor. Might not be it, but is worth starting there, as it is easy.
    • Hi everyone, I’m having an issue with my R32 GT-R. Sometimes, when the car goes over a bump or experiences some vibration, the 4WD warning light comes on the dashboard. When I check the code from the control unit in the trunk, it shows Code 19 – ETS Motor. However, everything seems to be working fine — if I turn off the engine and restart the car, the light goes away and everything functions normally. Has anyone experienced this before? Where should I start troubleshooting this issue? Thanks in advance!
    • I'm back from the dyno - again! I went looking for someone who knew LS's and had a roller dyno, to see how it shaped up compared to everything else and confirm the powerband really is peaking where Mr Mamo says it should. TLDR: The dyno result I got this time definitely had the shape of how it feels on the road and finally 'makes sense'. Also we had a bit more time to play with timing on the dyno, it turns out the common practice in LS is to lower the timing around peak torque and restore it to max after. So given a car was on the dyno and mostly dialled in already, it was time for tweaking. Luis at APS is definitely knowledgable when it came to this and had overlays ready to go and was happy to share. If you map out your cylinder airmass you start seeing graphs that look a LOT like the engine's torque curve. The good thing also is if you map out your timing curve when you're avoiding knock... this curve very much looks like the inverse of the airmass curve. The result? Well it's another 10.7kw/14hp kw from where I drove it in at. Pretty much everywhere, too. As to how much this car actually makes in Hub Dyno numbers, American Dyno numbers, or Mainline dyno numbers, I say I don't know and it's gone up ~25kw since I started tinkering lol. It IS interesting how the shorter ratio gears I have aren't scaled right on this dyno - 6840RPM is 199KMH, not 175KMH. I have also seen other printouts here with cars with less mods at much higher "kmh" for their RPM due Commodores having 3.45's or longer (!) rear diff ratios maxing out 4th gear which is the 1:1 gear on the T56. Does this matter? No, not really. The real answer is go to the strip and see what it traps, but: I guess I should have gone last Sunday...
