g-day dan ive had the na rb20 in my 32 for a while now almost off the p plater law and was hopefully keen to slap a turbo on it.

besides all the main parts and pieces i was hopein you could help me out with wat little things i would need to make it possible? cheers :)

A guy I know literally threw on the factory turbo, ECU, injectors, fuel pump, fuel reg, exhaust and intercooler setup and it was good to go, seems the older the gen car, the better they run with just the essential gear swapped.

He was getting a 13.9 straight off

G'day Guys, I'm looking at doing this to my R33 GTS, however I am a P Plater in qld :S...Say someone were to accidentally try and turbo my car what would they need? Also say the po po found out, would it be hard to take back out/tune?

Cheers Jake

they would need money...

if the popo found out tell them it got turboed by accident...

ya goose.

LoL.

keep all your stock gear handy :blush:

I'm just going to throw this out there as it wasnt mentioned (and had a bit of a conversation with N-DAWG about it via PM).

Has anyone.... other than me attempted to get this done (i am as mechanically useful as a rabbit).. with the stock ECU? And in this example, I mean the GTT ECU.

Given Victoria's very stringent laws regarding ECU - What have the victorians doing this done to get around this problem?

Has anyone tried this - Or in my case, been forced to try this? Or is everyone else out there running a copgyback and hiding the thing?

I initially did it using the stock N/A (R33 GTS) ECU with a GReddy eManage hooked up only to compensate for the larger injectors initially... a SAFC would have done just as well... then just wound the timing back a couple of degrees to fix the knock and it went fine. I eventually got the whole motor rebuilt with the smaller turbo pistons so now I'm running a stock GTST ECU with no aftermarket management (rebuild warranty and all that... gonna wait it out then whack the eManage back on and get it tuned) and it goes quite well... I guess as well as a fairly new stockish 33 would have (though with a FMIC, bigger zorst, boost controller, etc).

That's all well and good - How is it running with the GTS-T ECU? The issue (so I am told) is at least on my R34 is that there's no boost sensor, so the GTT ECU goes a bit haywire as it understandably cannot detect any boost.

In addition I've been told in order to get it all setup reasonably okay, a loom from a R34 GTT would need to be sourced to get this all running.

However, havent heard anyone comment about this in the thread, hence my questions as to whether this is a R34 issue, or specifically only an issue with the stock GTT ECU (to stay legal), or whether its just incorrect information and the original loom can be used.

I'm not about to say anything against Ray & Co at RE Customs, so I doubt its the latter but found it interesting noone else had mentioned this issue about looms, and was curious as to why it's such an issue for lucky me.. and given the car has been there for about 5 weeks now waiting on a Loom I figured I'd ask the question, but I'm sure it's because I'm being a difficult prick and want the car to be legal to avoid getting done on it later, and having to make it legal anyway in the future.

I'm lucky there... the R33's don't have a boost sensor! (Okay, they do, but it's only purpose is for the gauge on the dash... doesn't hook into the ECU at all)

On the R34s I believe this is a problem as the ECU does indeed 'see' boost (or a lack of it without the proper boost sensor and loom). You'd be better to stick with the N/A ECU and then just get some sort of basic air-flow signal adjustment (i.e. SAFC or the like) to compensate for the larger injectors. Wind the timing back a couple of degrees to prevent pinging and you should be fine.

...which leads me into the question regarding aftermarket ECU's and Managment with the aim of being 100% legal and whether anyone has done it before :wave:

Hmmm... 100% legal might be difficult (or expensive)... but if you are stealthy enough with your install of the SAFC or whatever it would be incredibly hard for anyone to pin you for it...

Hey guys, just curious what you have done with your brakes. Have you done a 5 stud conversion with brake upgrade? If not how do the N/A brakes handle with the extra power. I normally down gear to slow down and only brake for complete stops - could i get away with the N/A brakes?

My 33 already had a 5-stud conversion, so I didn't have to worry about it, but if you're only driving on the street, N/A brakes will be fine. Really, N/A vs. turbo brakes will only come into play when brake fade starts to kick in... i.e. on a track where you're leaning on them HARD corner after corner, but on the street I doubt this would be a problem. Sure your acceleration is improved, but that doesn't really mean you're going to be driving any FASTER... there's still speed limits, etc, so the stock N/A brakes should be fine.

I upgraded mine to R33 GTSt brakes. I did find the N/A brakes were more responsive and had a better initial feel, even after changing booster/cylinder to match the GTSt brakes... possibly something do do with the amount of fluid going through the calipers? or maybe simply the lower weight of the rotating parts?

I know when Dori done his conversion, particularly at the higher boost, he found that the N/A brakes were in need of serious upgrading.

You may get away with simply upgrading to slotted rotors, street/track suitable pads, braided lines (mainly if your brake lines are old) and a Master Cylinder Stopper to reduce firewall flex under heavy braking (also dependant on how bad the firewall flex is).

    • Yeah i found that alot of parts can be wrong or "very" hard to get the real right one. I already bought some brakes years ago on me "old" GT calipers and they were wrong too 😄  I told them too. Even send them pictures...but they said "EBC catalogue has them on my car... So i dont know what their answer will be. I call monday them and let them know that they are really not on my car. If they were they would be already on a car...
    • Welcome to Skyline ownership. Yes, it is entirely possible parts websites get things wrong. There's a whole world of inaccuracies out there when it comes to R34 stuff (and probably 33 and 32). Lots of things that are 'just bolt on, entirely interchangable' aren't. Even between S1 and S2 R34's. Yes they have a GTT item supposedly being 296mm. This is incorrect. I would call whoever you got them from and return them and let them know the GTT actually uses 310mm rotors. Depending on where you got them from your experience and success will obviously vary.
    • Hi...a bit a "development" on the brakes. I spoke to the guys where i get brakes from...and they are saying that 296mm EBC are for R34 GT-T. I then went to their site: https://www.ebcbrakes.com/vehicle/uk-row/NISSAN/Skyline (R34)/ and search for my car(R34 GT 1998 - it has GTT brakes) and it show me this USR1229 number and they are rly 296mm rotors... So now iam rly confused... The rotors i have now on the car are 310mm asi shown... So where is the problem? Does the whole EBC got it wrong or my calipers are just...idk know what?  
    • Oh What the hell, I used to get a "are you sure you want to reply, this thread is XX months old" message. Maybe a software update remove that. My bad.
    • This is a recipe for disaster* Note: Disaster is relative. The thing that often gets lost in threads like this is what is considered acceptable poke and compromise between what one person considers 'good' looks and what someone else does. The quoted specs would sit absurdly outside the guards with the spacers mentioned and need  REALLY thin tyres and a LOT of camber AND rolling the guards to fit. Some people love this. Some people consider this a ruined car. One thing is for certain though, rolling the guards is pretty much mandatory for any 'good' fitment (of either variety). It is often the difference between any fitment remotely close to the guards. "Not to mention the rears were like a mm from hitting the coilovers." I have a question though - This spec is VERY close to what I was planning to buy relative to the inboard suspension - I have an offset measuring tool on the way to confirm it. When you say "like a mm" do you mean literally 1mm? Or 2mm? Cause that's enough clearance for me in the rear :p I actually found the more limiting factor ISNT the coilover but the actual suspension arms. Did you take a look at how close those were?
