Ok guys, I just had an interesting weekend. I have finally pulled out the stock turbochargers out of my R32 GTR with my brother and I just have some queries that I hope you guys could help me with as I’m putting on some new N1 turbochargers and CES dump pipes (they look great btw).

Just a brief history of my car it has a chiptorque ecu, apexi air filters, stock inject. Direct clutch (single plate), HKS cam gears, and 3inch exhaust up to front pipes, and currently makes 230rkw on 13psi.

Ok for my questions, once I have put the N1 turbos and dump pipes on the car do I have to get the car re-tuned or will it be safe to drive?

Does anyone know where I could get my hands on some turbo gaskets for the N1 i.e. oil return gasket, exhaust gaskets etc…

Also should I change the exhaust manifold gasket as the one I have on appears to be in good nick?

I also have some 550cc injectors and twin RB20 80mm a/f meters, should I install them as well?

If so what HP/kw should I get roughly at the rear wheels after this has been installed and tuned?

Feedback would be greatly appreciated and I thank you in advance for your time and patience.

Cheer AS.

mate i have seen jim from croydons make 35o kw at the wheels with n1 turbos'. i was beside the car when it pulled this figure. once you have done the turbos take it back to get the cams dialed in and get the computer retuned. i don't think those 550 are going to last you very long if you keep modding the GTR.

N1(ball bearing) are a top turbo and as long as you got the system upgrade around them you should make 300rwkw with out to much trouble just be care with the injector normal 700cc are the go but 550cc will still make good power

best of luck

ps how are you enjoying the turbo change on the 32 (pain in the arse) hehe

']post some pictures of the differences between the standard one and the n1 turbo if you can. hope all goes smoothly!

AAAhh, and my bro started to get shitty because I wanted to take pics of the turbos side by side (well wasnt really the fact that I was taking the pic, just that I wanted ti align them properly so you can actually compare them). Here they are the pics.

Yeah I was pretty bitchy, but I appreciate it now that's 4 sure. These pics really make it difficult to spot the difference but hopefully the gains from such turbs will show the true differences soon.

Yes, I finally put the nismo turbos & dump pipes on the car and the car drives as if it were stock. However, the car now has a much more rumblier noise to it (very sexy) and can here the turbos spool up. Before the tune I will be putting on larger injectors (most likely 700cc) and replace my A/F metres with RB20 one.

My brother also installed my E-boost for me but is not correctly working yet.

Once the tune is completed I will post before and after pics of the dyno graph for everyone to see.

By the way does anyone know if I should replace my standard fuel pump with an intank pump i.e. apexi, nismo etc.. or with an external pump such as a Bosch 044???

Cheers AS.

you sure you didnt mix the turbos up and put the stockers back on? :alcoholic wouldnt that be a bitch

Nope, the nismos are installed!!

What he didnt mention that its only running 7.5psi. It you rode in it you wouldnt think so because it is pretty fast (it doesnt drive like stock as he mentioned...he's just to use to his old power output at 13 psi: 233rwkW). The nismo turbos have made a big difference because I remember the car running about 8psi with the standard turbos and the difference is quite noticible. Its probably making 190-200 rwkW at his current boost level which means at 17psi it will go really nice.

BTW his old turbos are going on my car... yes a twin turbo FJ20!

Cheers

    • 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. 
    • 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.
    • Damn that was hilarious, and a bit embarrassing for skylines in general 😂 vintage car life ey. That R33 really stomped. Pretty entertaining stuff
    • 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
    • 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.
