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!

      Yup. You can get creative and make a sort of "bracket" with cable ties. Put 2 around the sender with a third passing underneath them strapped down against the sender. Then that third one is able to be passed through some hole at right angles to the orientation of the sender. Or some variation on the theme. Yes.... ummm, with caveats? I mean, the sender is BSP and you would likely have AN stuff on the hose, so yes, there would be the adapter you mention. But the block end will either be 1/8 NPT if that thread is still OK in there, or you can drill and tap it out to 1/4 BSP or NPT and use appropriate adapter there. As it stands, your mention of 1/8 BSPT male seems... wrong for the 1/8 NPT female it has to go into. The hose will be better, because even with the bush, the mass of the sender will be "hanging" off a hard threaded connection and will add some stress/strain to that. It might fail in the future. The hose eliminates almost all such risk - but adds in several more threaded connections to leak from! It really should be tapered, but it looks very long in that photo with no taper visible. If you have it in hand you should be able to see if it tapered or not. There technically is no possibility of a mechanical seal with a parallel male in a parallel female, so it is hard to believe that it is parallel male, but weirder things have happened. Maybe it's meant to seat on some surface when screwed in on the original installation? Anyway, at that thread size, parallel in parallel, with tape and goop, will seal just fine.

      How do you propose I cable tie this: To something securely? Is it really just a case of finding a couple of holes and ziptying it there so it never goes flying or starts dangling around, more or less? Then run a 1/8 BSP Female to [hose adapter of choice?/AN?] and then the opposing fitting at the bush-into-oil-block end? being the hose-into-realistically likely a 1/8 BSPT male) Is this going to provide any real benefit over using a stainless/steel 1/4 to 1/8 BSPT reducing bush? I am making the assumption the OEM sender is BSPT not BSPP/BSP

      Jacks that fit under GTR lips that can reach the subframe?

      I fashioned a ramp out of a couple of pieces of 140x35 lumber, to get the bumper up slightly, and then one of these is what I use

      I wouldn't worry about dissimilar metal corrosion, should you just buy/make a steel replacement. There will be thread tape and sealant compound between the metals. The few little spots where they touch each other will be deep inside the joint, unable to get wet. And the alloy block is much much larger than a small steel fitting, so there is plenty of "sacrificial" capacity there. Any bush you put in there will be dissimilar anyway. Either steel or brass. Maybe stainless. All of them are different to the other parts in the chain. But what I said above still applies.

      You are all good then, I didn't realise the port was in a part you can (have!) remove. Just pull the broken part out, clean it and the threads should be fine. Yes, the whole point about remote mounting is it takes almost all of the vibration out via the flexible hose. You just need a convenient chassis point and a cable tie or 3.
