Rb20det Turbo Removal

Hey everyone.

I've got a 32 gts-t that I bought several months ago, but I don't actually have my licence yet, I'm on my Learners (have been for a while - laziness) and haven't got around to getting my Ps yet because I haven't been working.

Now with the new laws that are coming in, I'm not going to be able to drive my car until I'm on my full licence, as I can't get my Ps in time before September 4, the date the laws are in effect from.

My basic, rough plan is to remove the turbo on the RB20 and just drive it N/A for a couple of years, and spend that time working on the body/suspension/brakes etc, and once I was on my full licence either look at putting the turbo back on or upgrading to a different motor. And yes I know it won't be fun driving an N/A 2L for 2 years.

1. Is this even a good idea or is it going to be a whole lot harder than I think?

2. What in particular do I need to change (turbo removal obviously, but manifolds, AFM, tune, exhaust (it has a 3" turbo back at the moment), throttle body?)

3. Are there any other factors I'm not aware of that will need addressing?

I don't particularly mind the stupidity of removing the turbo and then putting it back on again 2 years later, or if I lose a little bit of money, I just want to drive my car.

Cheers guys

Bad idea. Removing a turbo from an RB20DET engine will make it weaker than a factory RB20DE. You will have people in 1.3L cars out running you.

Sell the car or workshop it until you get on your fulls.

sell the car and buy a NA version. as iseekool said, a turbo engine running without the turbo will put out much less power than the NA version. i'm guessing it would be somewhere around 40 to 50kw at the wheels. in all seriousness a 1.3L car will more than likely be able to beat you in a race. it will be beyond being "not fun" to drive. it will be dead set shocking to drive.

you really should've done some research before buying the car.

ah touche I was afraid that might be the case. How much roughly for a RB20DE?

Edit: and by the way, I have a personal loan for the car that is far from paid off, and I owe more on that than the cars worth, hence the reason I haven't just sold it and moved on. I'd rather keep it and just keep paying the loan every week, then at least by the end of it I'll still have a car to show for it, not a 4k loss lol.

I bought the car turbo and with the intention of driving it turbo, why would I buy a turbo car originally and intend to convert it to NA straight away?

I wouldn't know the price for an RB20DE... but What I do know is that it would be damn cheap (almost scrap value maybe????) because they aren't that powerful in the first place, and there isn't much love for them unless they have a turbo.

If you cannot part with the car, I'd workshop it (keep in a garage) and work on it - maybe a few upgrades/fixes. By the time you are on your fulls you will have a nice car to drive.

But really selling it is the way to go....

You will get fined by the police regardless if you have the turbo in or not as the car's build plate shows it has a turbo... the the eyes of the law you are still driving a "turbo" powered car.

You are better off driving with the turbo on and just risking it and hope not to get caught - But I do not endorse that.

note: I'm not trying to be rude - but this has been covered many times before on these forums many times with other peoples experiences.

ya but i wasn't asking how to do it i was just asking if there were any particular things i needed to change when removing the turbo.

i might just do what you said, keep it and work on it for a couple years, at least when i get my fulls i'll have a really nice car.

and i'll just buy some cheap car in the meantime for a daily.

Yep. :(

Good choice.

By the time you are on your fulls you will have something quite special.

An exemption is the first thing I'm going to try for, but the government website about the new laws that I checked out made it sound as if you needed your Ps before the date AND had to own the car.

I might ring up somewhere and ask them if I'm going to be exempt because I bought the car months before.

didn't realise you were in WA where the restirctions are only just coming in. you'd be suprised how many dicks we get coming on here who buy a turbo skyline knowing that they can't drive it because they think you can simply pull the turbo off it and have it go like a NA.

      You just need to remove the compressor housing, not the entire turbo. I would not be drilling and tapping anything with the housing still on anyways.

      Mistakes were made, my R34 Story

      By Kinkstaah · Posted

      So, I put my boat on a boat. First of all, I'm going to come out and say it. Why is Tasmania not considered a holy goal, an apex that all road-legal modified cars go to, to experience? This place is an absolute wonderland of titanic proportions. If people are already getting club runs for once in a lifetime 30 person cruises to Tassy then I've never seemed to see it. It is like someone replaced the entire place with an idyllic wonderland for cars, and all of the people living there with paid actors who are kind, humble, and friendly. Dear god. After doing a lap of almost all of the place I've found that it's a great way to find out all of the little things that the car isn't doing quite right and a great way to figure it all out. All in all, I drove for 4 hours a day for a week and nothing broke. I didn't even need to open the engine bay. This is by all means a great success, but it has left me with a list of things to potentially address. I also now have a 3D printed wheel fitment tool which annoyingly hasn't got any threads in it to actually assemble it. I might be able to tape it together to check the sizing I actually want to use, but it'll likely involving pulling the shocks out to properly measure travel at least at the front, and probably raise the car while I'm at it, at least in the rear. I scraped on quite a few things and I'm not sure how else to go about it. I was taking anything with a bump at what felt like 89 degree angles. And address those 10 other tasks. And wash the car. God damn it is dirty. And somehow, the weather was perfect the entire time - And because I was on the top of Mt Wellington it turns out it was very much about to freeze up there. I did something I typically never do and took some photos up there in what must have been -10 and the foggy felt like suspended ice, rather than mere fog. If you own a car in Australia, you owe it to yourself to do it.

      By cosline · Posted

      Hi, I have a r32 gtr transmission. Does any of you guys have an idea how much power it will hold with the billet center plate and stock gearset? At what power level and use did yours brake with or without billet plate? Thanks, Oystein Lovik

      Spotted on the street....

      By Rezz · Posted

      Saw this replica police car based on a Mitsubishi Starion XX parked next to a 'police box' (it's literally a box) in Hirohata, Himeji City in Hyogo prefecture the other day. It's owned by Morii-san who is a local Mitsubishi Starion enthusiast. According to a local radio station blog post, he always wanted to make a police car himself based on ones he saw in his favourite Manga comics.  As it's illegal to modify a car to look like a police car and drive on the road, Morii-san tried many times to get permission from Aboshi police station headquarters nearby. They refused initially by after they got tired of that they granted him permission. However, the car can only be displayed on private property and obviously can't be registered as long as the police livery is present. The car was completed at a cost of 1.5 million yen (US$ 10,000) in addition to the car cost. A location was chosen outside Hirohata Police box where the car can easily been seen from the street. Morii-san has two other Starion road cars, both widebody GSR-VRs.
