I have a R33 GTST 1.5, the engine has done around 160,000km's

There is literally no mod, all stock standard except a 3inch exhaust ......

what would be the next upgrade i need to do to gain extra KW??

what manual boost controller would you recommend??

How much psi can the RB25det handle with the stock??

How much psi can i handle with the stock intercooler?

Turbo back exhaust if you only have a cat back, then panel/pod filter. Cut and ground the boost solenoid. But before anything else... Search! This has been covered many many many many many many times

if i could start all over again, id start with engine management, depending on your plans for the car are, then fmic , a good front pipe (turbo to cat) panel fiter with some air box mods to get more outside air in. oh and change yur fuel pump if its still stock :(... or do a search :)

Hi there Glenn.

If you take the time to read this thread:

In particular this thread "What Mods to do first":

You'll be well on your way :)

R34 side mount intercooler $150ish

r32 wastegate actuator (holds a safe 10-12psi) $40

K&N panel filter $100ish

Apexi safc fuel computer $250 second hand + tune $150

Maybe an MBC if the r32 actuator doesn't hold the desired boost $35

Should see 200kW with this combination.

id be making sure that your timing belt, tensioner and water pump had got replaced at its 100,000k service...otherwise that would be the very first thing i would do before potentially giving that vehicle more power considering its kms.

with mine i did mods in different stages. first i had a full 3.5" exhaust (3" is fine), larger front mounted intercooler, k&n filter and a bleed vavle boost controller set at 10psi = 175kw rw

later i got a power fc computer, bosch 040 fuel pump and tune = 204kw rw

now i got a hiflow t3/t4 turbo, z32 afm, and a nismo fuel pressure reg =241kw rw

later i plan on splitfire coilpacks and 480cc injectors for 250+kw

Hi Guys

I just recently purchase a r34 side mount intercooler and what i have realised is, its very responsive now........i notice it in a hot day....

Now apparently from my mechanic i only have a cat back 3inch exhaust....i dont have a turbo back dump pipe unfortunately :laugh:

so my question is, whats best for my next purchase?

turbo dump pipe?

Manual boost controller + boost gauge to 11psi??

or

hunt around for an R32 wastegate & actuator

im tempted to go with the MBC + boost gauge to 11psi.... as that will give me more KW....

whats your thoughts??

Playing the bad man forum patron ... :)

If I went to a bird watching forum, I would assume the question "best cheapest binoculars to start off with" or "best, cheapest paint roller that gives uber even coverage, for a newbie" on a niche interior painting forum, would have been asked before.

Hitting that search button with a ruthless "enjoy sitting in wee drenched jeans" manic depressive anxt, will provide a wealth of experiences.

If you springboard off other ppls experiences (Like Sambo33) plus have a little desire to tinker, you can SKIP technical, and fiscal issues others have had when modifying; hence the use of a forum. Don't get caught up using fish tank pumps for blow by excavation or Korean HID's when you coulda had those sway bar's or high flowed turbo.

Don't mean to be condescending, im just an a55hole who trys to tell it how it is should be :D

    • Yep, pretty much what you said is a good summary. The aftermarket thing just attached to the rim, then has two lines out to valve stems, one to inner wheel, one to outer wheel. Some of the systems even start to air up as you head towards highway speed. IE, you're in the logging tracks, then as speeds increase it knows you're on tarmac and airs up so the driver doesn't even have to remember. I bet the ones that need driver intervention to air up end up seeing a lot more tyre wear from "forest pressures" in use on the highway!
    • Yes, but you need to do these type certifications for tuning parts. That is the absurd part here. Meaning tuning parts are very costly (generally speaking) as well as the technical test documentation for say a turbo swap with more power. It just makes modifying everything crazy expensive and complicated. That bracket has been lost in translation many years ago I assume, it was not there.
    • Hahaha, yeah.... not what you'd call a tamper-proof design.... but yes, with the truck setup, the lines are always connected, but typically they sit just inside the plane of the rear metal mudguards, so if you clear the guards you clear the lines as well. Not rogue 4WD tracks with tree branches and bushes everywhere, ready to hook-up an air hose. You can do it externally like a mod, but dedicated setups air-pressurize the undriven hubs, and on driven axles you can do the same thing, or pressurize the axles (lots of designs out there for this idea)... https://www.trtaustralia.com.au/traction-air-cti-system/  for example.... ..the trouble I've got here... wrt the bimmer ad... is the last bit...they don't want to show it spinning, do they.... give all the illusion that things are moving...but no...and what the hell tyre profile is that?...25??? ...far kernel, rims would be dead inside 10klms on most roads around here.... 馃槂
    • You're just describing how type certification works. Personally I would be shocked to discover that catalytic converter is not in the stock mounting position. Is there a bracket on the transfer case holding the catalytic converter and front pipe together? If so, it should be in stock position. 
    • You talking about the ones in the photo above? I guess that could make sense. Fixed (but flexible) line from the point up above down to the hubcap thingo, with a rotating air seal thingo. Then fixed (but also still likely flexible) line from the "other side" of the transfer in the hub cap thingo up to the valve stem on the rim. A horrible cludge, but something that could be done. I'd bet on the Unimog version being fed through from the back, as part of the axle assembly, without the need for the vulnerable lines out to the sides. It's amazing what you can do when you have an idea that is not quite impossible. Nearly impossible, but not quite.
