hey all,

I am the proud owner of a fresh off teh boat cefiro with the RB20DET engine under the hood, it is my first time owning a turbo charged ride (past cars were silvia and supra both NA)... now this engine is almost completely stock apart from a 2.5" exhaust system.

What I want to know is what would be the most sensible upgrades to make on this engine to get a bit more punch.... I am not going to be able to fork out thousands in the near future so i am looking for the basic upgrades.

So air pod filter and ecu remap have been reccomended by one or two people, but I thought I would get a general concensus from the wider SAU population!

Let me know what you think.... If you have a resource online showing someones build up of an RB20 that would be tops too, i did google but didn't get too much success.

cheers all!

Luke

if it has an exhaust already then do the following if ur on a budget. The prices are what you should expect but will differ depending on where u go and who does the work for you:

-POD ($80 inc adaptor from Autobarn or Repco... fit it yourself and keep the stock box.)

-Bleed Valve ($60-$90 and run about 13psi on it)

-ECU Remap ($250-$300 depending where ur located allow money for dyno tuning if required. This will need to be remapped everytime you add something performance wise to the car.)

-Get some secondhand wider tyres for the rear like 235s or 215s ($100max sometimes more for 17s.)

That alone will get u into the mid 14second range (manual right?) and if ur a good driver into the lowish 14s. (pretty much the exact setup as was on my R32 except the 32 had damper adjustable suspension and a HD exedy clutch.)

-Finish off the exhaust if not done already with a dump and front pipe ($250 to $300)

-Hi Flow Cat ($230)

-Then get a nice HD clutch of some sort ($700+)

-Suspension setup (Can get some decent height or damper adjustable second hand jobs for less than a grand. S13 stuff should bolt straight up)

Then i would suggest upgrading the brakes on it... best to upgrade the whole system to something like the R32 GTST or R33 GTST or even the Z32 300ZX brakes like whats on my ceffy.

cheers for the replies, Inark, handy stuff mate. but yes it is a stockers auto... so I know I am losing a bit with the auto but its a daily driver in sh*tty city traffic so its been suiting it well.... the tweaked power is for the weekend fun....

ok well the pod is a sure thing, has anyone got a recommendation of the type to buy for easy fitting to the stock airbox unit?

so can someone tell me a bit about what a bleed valve does and how it is fitted?

the suspension is done, I had it dropped on sports ryder equipment a few weeks ago...

cheers

autos are fine man... at least they are consistant unlike us :P

PODs... just get the cheapie one i suggested... you remove the std box... easy enough... 4 clips to get the top off... remove the filter panel and undo the 4 10mm bolts which go into the chasis. also disconnect it from the pipe leading to the turbo via the 8mm hose clamp.

Shouldnt be too hard to figure out how to attach the adaptor plate to the pod and then to the pipe where the box was connected to.

bleed valve is a little more difficult.. i will put up my guide on how to do it when i get home... it has plenty of large pictures to guide u through. A bleed valve is whats used to change the amount of boost you are running by bleeding air.

forgot to add u will also need a boost guage... there is no shortage of 2nd hand cheapies going around on most of the performance forums so dont be a stranger to the For Sale section...

i also have an installation guide on them too :P but its for an R32... BUT is done the exact same way and on the same engine so its all good :)

How much would an average comprehensive car insurance quote be for an R32 GTS-T?(most likely under my parents name, not quoted on me when im 18)....Im interested to know as i am looking into getting one when i get my P's as a first car. If anyone can find out for me that would be great.

Thanks in advance. :(

So yeah back on topic...

What I have is stock, with nice exaust. Prob GTR fuel pump, nice big pod, a bit of 3inch pipe going from the front bar to right in front of it. Bleedvalve at 12-13psi, depending on the weather (found it was faster on this than 14psi, I guess because of effeciency) Malpassie, and, a catch can, which I personnally found no gain from.

Anyway, this got me 195rwhp. All the mods I found a dencet boost from, I think I have spent $300... But I did get stuff cheap, and a fair bit was already on the car.

And with the auto... You can spool on the line better, and potentally get a better launch. You want faster times on the strip, let the tyres down!

      New fix for low tyre pressure from bmw

      By MBS206 路 Posted

      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!

      Anyone know this frontpipe?

      By sunsetR33 路 Posted

      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.
