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!

      Possible swap on R34 RB20DE NEO?

      By Kapr · Posted

      Hi. A little bit of an update. It maybe(hope not) looks like i would need a new tranny(it would be "maybe" a cheaper or better option anyway) So i need some info. I know i need a different propshaft(i can make custom one) LSD is not a problem cuz the engine will be still(for now) N/A RB20. So if i buy RB25DET NEO tranny...is there something else i need? I read something about push/pull type but i do not know if i need to "change" something or i can just plug n play onto my engine a go? Thanks for the advice

      Turn signal wiring question

      By OakvilleGTR · Posted

      Good morning all, Bit of a random question but figured I’d finally throw it out after wondering for a long while. Before I start, I'm hoping to do this purely out of personal preference. I think it would look better at night, and don't mind at all spending a few hours and dollars to get it done. I've copied this from a non-Skyline specific forum, so I apologize for the explanation of our headlight switch setup that we all know. Here we go: Zero lights (switch off) Parking lights (switch position 1) being a rectangular marker on the outside of the housing, my low beam being the projector in the centre (position 2), and a high beam triggered by my turn signal stalk. Most North American cars I’ve owned of this era have power to the amber corner (turning indicator) light as part of the first switch (parking lights). I’d love to have these amber corners receive power when the headlights and parking lights are on (headlight switch), yet still blink when using the turn signal which is of course a separate switch. Hopefully I’ve explained my question correctly. Is anyone aware of a way in which I might be able to achieve this? Thanks in advance

      Mistakes were made, my R34 Story

      By Kinkstaah · Posted

      My heads are cathedral port! It's likely possible, but I don't want to add any extra moving parts (I know they don't move) between the heads, manifolds, etc. It will also affect how injectors/fuel rails etc sit and I don't really know if it would change how the FAST manifold goes/sits/fits. I have the LS6 steam pipes already as I have a very late LS1 block so it should be fine. I couldn't find anyone who had ever actually used one for this purpose, it seems 100% of people grind the water pump. The thermal spacers are 12mm and are half way to the cost of the newer water pump anyhow... so if it comes to that I suppose I'd rather buy a new pump. The bearing in the pump I do have is a little.. clunky, but it hasn't done that much time and I never noticed it when the car was together in the past few years, so..

      Lower A arm Skyline v35

      By sonicii · Posted

      The bushing has failed, not all that uncommon for a car of this age.  Any mechanic should be able to push in a new bushing for you, or you can probably buy the entire lower control arm, complete with bushes.

      Could you not use "thermal" spacers to give the clearance, like the ones I used between the blower and head? That raised the manifold height by around 10-15mm Albeit the ones I used were for cathedral ports, but I assume they have similar for rectangular ports????
