My R33 Turbo In On My Rb20 Don't Know Where Should Go Next

Hello

I have a R32 GTS-T. I put a R33 turbo on it. It has a HKS adjustable acuator. I have it set at .5 bar. Going to set it at .8 or .9. I have a catback exhaust, intake.

What else should I do next? I have a R34 SMIC that I haven't put on yet.

I want to get the most out of this turbo that I can. Should I get a GTR fuel pump or a Nismo 4L pump? Should I put in GTR injectors or Nismo ones or keep stock? Do I need a aftermarket computer now? Should I go with the down pipe/ front pipe? Do I have to tune if so?

Later, in the winter time, I will buy a friends TD06 but cant afford it right now. Later going to get Emanage, and FMIC.

I have read and read and I really don't know where I should go from here. There is a big improvement in response and speed just from having the R33 turbo on there.

Help!

I want to do next important upgrading!!! I live in Japan and the area where I live gets only about 30-32 degrees celcius in the summer on average.

well i have a stock rb20 with rb25 turbo, 3" turbo back exhaust (no cat), bosch 910 pump with surge tank, 600x300 fmic, safc II, manual boost controller (turbo tech) & thats it.

gives a responsive 250hp atw, but larger turbo, injectors afm & nistune flash will be going on pretty soon.

Cool

Why the surge tank? Does the fmic give much lag? The reason I am going with the R34 smic is because I read on this forum that it is about 50% bigger than stock. So its shorter travel for the air to the turbo so hopefully not a lot of lag.

What kind of larger turbo are you putting on? What is a nistune flash? Why a safc II instead of a computer?

Thanks

I would put the exhaust and r34 smic before boosting. Its best to no not go past 14psi on stock r33 turbo otherwise it starts to get risky. But when u do boost, you should get a tune.

I will finish the exhaust(downpipe, front pipe, better cat) after I get a computer. I will put the smic on within the next two weeks. Busy with work. I will not be able to buy a computer and tune for about 1 to 2 months due to having to use money for something else. Is this fine? I will make sure not to set it about 14 psi.

yeah the surge tank is a bit of overkill but it & the pump were installed by the previous owner when the car had a different motor.

this setup is very responsive with sfa lag imo & i wouldnt run anything else but a decent fmic.

it has custom cooler pipes & the cold side pipe (after the cooler) is fairly short compared to some setups ive seen.

anyway i dont mind a bit of lag especially if you can run say 20psi & have a real good hit of power.

the safc was put on by a previous owner cause when he bought the car it had been bought back to pretty much stock. it was running autronics & hks turbo etc before he bought it.

the car is making reasonable power with its basic mods & a lot of that is probably due to the safc.

im going for a nistune flash instead of a new complete ecu cause they are only about 800 bux tuned & do the job i believe.

the turbo thats going on is a s/hand (6 months old) Apexi AX53B70 P-25, its a bit smaller than i probably would have liked but for $1000 for the complete apexi kit (turbo, dump, braided lines, etc) it was pretty hard to pass up.

cheers

Hi mate I have headed down the same path as you when you do decide to

go down the path with a computer upgrade to handle all these mods.

I would higly recommend that you go n see Dr Drift for a reflash chip for

the std computer as this is what I have done and the results have been

unreal totally different car to drive shit loads more mid range and can

drive the car on the throttle more around the race track.This has been

the best mod I have done on the car so far,and a lot cheaper than a pfc.

Good luck with it

he lives in japan so are these reflash options really viable?

can he send them his ecu & they modify it & flash a generic tune to suit his mods?

i would have thought a live/real time tune was the only type worth having

Are you telling me that there is no-one in Japan that can do a CHIP for a car/motor/ecu that's been around IN JAPAN for 19 years?

Not saying DR-Drift is good, but he lives in Japan FFS.. we get cars come over here with MINES chips etc.

why would he not do this instead of getting DR-DRIFT or toshi or cef11e to tune for a fuel we don't even have here??

There are places here, but I dont know where a lot are. Plus they charge crazy money here for a lot of this stuff. I try to put on as much stuff as possible getting help from friends. But none of my friends know how to tune.

How can I contact DR. Drift?

Fair enough I didn't read that he lives in Japan FFS!

      Mistakes were made, my R34 Story

      By Kinkstaah 路 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.

      R32 gtr transmission strength, billet plate

      By cosline 路 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 路 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.
