I will be purchasing a r33 GTS-T in the next few months and because of the new p-plate laws coming in on july first in Victoria I wont be able to drive a turbo car while on my p's. The price difference between the GTS and GTS-T is next to none and the uprated diff on the GTS-T seals the deal. I was wondering what problems would I have removing the turbo? besides obviously needing a non turbo exhaust manifold. Would I need to get the ECU retuned or would the car adjust to it and so forth.

Thanks In Advance

prob gonna need new ecu too. 1 that isnt tuned to have a turbo like the stock ecu from the r33 gts. that might help you out but i would go see a performance shop and enquire some more.

ring the Ray at RE Customs. he'll be a big help

yes it would still run.

It would just be like drivng around off boost.

How ever good luck trying to convince the coppers that you have taken the turbo off....when the compliance plates state RB25DET andnot RB25DE.

Also you would have to remove all the cooler piping and make/buy a new intake (NA) aswell as get a new front pipe.

The RB25DET with out the T will make less power than the 25DE as it has lower compression. less ign timing and different cams with are designed for forced induction.

But yes it could be done.

The car is still build plated as a Turbo model.

The car is still registered as a Turbo model.

The car still requires all the Turbo model pollution gear to control it for EPA purposes

Playing with the ECU is also illegal and, for the R33, pretty much a pointless excercise.

Thre have been a dozen threads on this mate. You can not get around the law by simply "removing the turbo". You think the makers of these laws didnt think that people would attempt this?

You cant do it legally, so buy a N/A like the law states you must :)

Its as simple as that really.

I spoke to vicroads and they said to me that as long as I removed the turbo and it conformed to the power to weight ratio there wouldnt be a problem. To be sure I got it in writing from them. So I dont know what the score is :P

as stated best route is buy a N/A gts skyline and go from there, if that bothers you get a small 4 cyl car drive around for 3 years save more money and who knows with discussions of bio fuel and god knows what in 3 years things may be different that way 1. You have saved money all round on insurance and fuel and other things, 2. you can put that money towards something better?

I agree with the others, i bought a GTS however i am replacing it with DET motor as i have got a screw logged in my piston.

BUt buy a GTS and you'll have more power than the GTS-T (without turbo) because the NA engine was built to allow for (no-boost) and therefore a higher compression.

Just adding my thoughts..

:):D:O:blink: WTF!!! I wanna hear the story behind this!!! lol

But to be on topic, yeah definetely go the GTS, removing a turbo on a GTS-t when there is an NA version of the same car allready available........ummm where is the logic in this??? The diff being different (which you will not be able to tell is different just from amatuer driving) is hardly worth the money involved in turning into an NA car, and yeah as the guys above have allready said, its a turbo car from factory meaning you cannot drive it under P plate laws, regardless wether you drop a hyundai excel motor in it or not lol

Dude - for f**k's SAKE don't get a Skyline on your P's. Do You REALLY want to be pulled-over EVERY day THAT BAD ? ? !

I believe the new P's rules say "No mods at all to engine" - so removing the Turbo would be a mod.. . Catch 22. Plus the RB25deT motor has lower compression than the N/A Motor, so it'd be heavier on fuel than necessary, AND gutless.

Maybe get a 240Z for 3 years, & learn about hardcore maintenance ? ? ?

      This looks great! Awesome to have the 5 speed with an LSD in this. The Recaro's look like SR2's or SR3's. It's a shame they've been retrimmed as they would have looked sweet in their original colours. I think I'd want my agent to be a little more up front and informative too. I've never imported but I reckon it would make me a little nervous, so the more info the better.

      Thanks for doing that Duncan! Makes you a good person in my books. We don't get kangaroos or wombats here. But we have bats and it's similar. AFAIK it's often the mums with a baby attached that get hit because they drop lower when starting from a tree. If you hit an animal, check on it. https://www.ifaw.org/au/resources/wildlife-rescue-app An app to get the closest wildlife rescue contact.

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

      My dream is also to have a proper hoist, but I don't think it will ever happen. My quickjack is probably as close as I'll ever get, it really is very good though.

      Yeah we keep on in the dailies, it is pretty poor how many animals get hit and the driver leaves without checking....have saved a couple of little ones over the years. Bit of a gruesome job though, pouches generally need to be cut open because they are so tight and often the joey doesn't realise mum is gone so they are still locked onto the teat. I checked the modules in front of the DS wheel where an oil cooler should go.... There is the radar unit - that can go for race use) One of the 2 HX water pumps, the silver cylinder. That needs to be kept but might be able to be relocated But the bad news, the big computer mounted vertically in front of the wheel (blocking any potential air exit) is the electric steering computer. That is required until/unless i do a hydraulic steering conversion, and in CAD based modern car design it is not like I can just pop a big unit like that somewhere else (plus the loom would be too short anywhere else too). So, the passenger side is OK to clear out (just use a smaller washer reservoir, potentially elsewhere), but the DS no beuno

      Well, all the best with the new camry It was interesting to hear about the UK process, it is generally a lot more streamlined here with a shipping agent looking after all the import side (noting the exact final price can still be a surprise.....) and I've used a few different brokers on the japan (or US) side, and never had any trouble with any of them....luck of the draw I guess. You mentioned you didn't get the auction sheet (understandable since you bought it from a dealer, not auction), but I always try and get hold of that because they are pretty thorough. I've imported 2x R grade vehicles over the years and both were fine, repairs in Japan are pretty thorough compared to here in Oz.
