Hello

I am new to tuning. I have a Skyline r32 gts-t stock except for the exhaust which is a sports exhaust.

I want to make my car at least 300hp.

Dont know where to start.

Somethings I have seen and read are change cams, fuel injectors, fuel pump, turbo.

I want to change cams but dont know what I am looking for. I read and have been told to get used GTR cams, I have checked Japanese websits such as Tomei, and seen upgrade cams. But dont know what to do. What else do I need if I do that? What will it help do?

Also I have been told that any mod requires a tuning of the computer to make the car run right. So does this mean that any change or mod you have to have the computer tuned? If so, how do people afford this if they are constantly modding their car. What is a cheap computer to get? Can I get my stock computer upgraded?

Please help, I have researched and asked questions, but everyone tells me a different thing here. I want to do this but where do I start? I am American but live in Japan

Help please.

std R32 gtst ECU can be chipped and tuned

Cams would not be the first thing you do - look at the slide turbo upgrade thread for results of his highflows,

turbo injectors fuel pump should be the first things then tune

Cool, I know Austrailan prices are alittle different from Japanese prices but what do you think the cost of rechipping my ECU cost? and How far can I have it rechipped?

Also dont have tons of money so need to be cost watching so how much do you think a good but not expensive turbo should cost and should I get aftermarket turbo, injectors, fuel pump and intercooler or should I get used GTR parts?

Do I need to rebore my block(I read something about this)

My car has only 95000 km on it and has not been used for racing.

Thanks

ok, reboring the block is an engine rebuild - so no you dont need that unless it has issues.

GTR front mounts are good, but usually the cheaper kits from just jap etc are just as good and come with the piping you need

gtr injectors are good upgrade on the cheap - but need ECU to do this

Remapped ECU - Dr Drift based in Melbourne does them . AFAIK around $600 and up for a tune

start with a front mount and a boost controller - bout $600 ish if you install yourself

then save up for the rest :) dont rush into it and read around a bit cos i dont think you looked too hard :laugh: try the rb20 dyno results thread at the top of this section for a starting guideline

Ok so I should keep stock injectors, fuel pump and just go with a front mounted intercooler, bigger turbo(rb25?) and ecu rechip and tune? How far will this boost me?

Do I need to change to a sports cat, and down pipe?

Thanks

go 2 the rb20 turbo upgrade thread and go from there. it depends all about your budget. Basic Mods front mount intercooler, POD Filter( is your option though) fuel pump, dump pipe (which is from turbo back), front pipe (after the dump pipe), Racing Cat, Cat-back Exhaust (after the cat converter) RB25 ( From R33 Serious 1 or 2 R34 GTT). and remap ecu. dont think about boost too much boost will better running in 12psi in save area.

Im not too sure wat power will make but will be very close to wat u aim for.

Goog Luck

Ok so will start getting parts and saving money. When do I need to replace ECU? What is a Aplexi S-AFC, a Power FC ?

THanks

when u get injectors bigger turbo then get ecu, safc is a piggy back which is measure air and fuel mixtured and power fc is a proper ecu which u can tune what u want. im a fan of power fc and microtech. power fc has 3 differents model which is normal power fc, power fc D' Jetro ( which is u dun need air flow meter) and power fc pro.

Hope these will give u more idea.

Good Luck

Speak to Quicny777 and use the same turbo as he is. Speak to your local tuners and go with whichever ECU they claim to be able to tune the best for you. Be it Power Fc, Microtech, remapped std ecu , WOLF etc are all the easy options.

Standard cams are fine for your target 300hp, just get a good 80mm exhaust, interciooler, bigger injectors and a good tune. You will make 220rwkws reliably and easily

      R32 GTS (RB20DE) Injectors Replacement

      By GabsReDeal · Posted

      I refreshed the OEM injectors with the kit and connected it up. It now ideals okay even with the IACV removed. Driving still has the same cutoff issue like the 550cc injectors so the issue is somewhere else. I bought FPG's Fuel Pump Hanger. I will be installing it next, but it is not as straightforward as I thought it was with my limited wiring knowledge and no instruction on the specific model I purchased (FPG-089). I also got the incorrect billet clamp as I could not find info on the OEM sizing.

      Stop looking at the garage floor, and turn the radio up a bit louder if there's any strange noises...

      Unknown sound similar to BOV on positive boost with partial throttle RB26

      By GTSBoy · Posted

      No. Turbo shuffle and surge/flutter are not the same thing. Specifically, on a GTR, turbo shuffle has a definite meaning. On a GTR, the twin turbos are assumed to be the same thing and to operate the same way, exactly. In reality, they do not. Their exhaust sides are fed and exhaust a little differently, to each other. Their inlet sides are fed and exhausted a little differently, to each other. Consequently, when they are "working" they are often at slightly different points on the compressor map compared to each other. What this means, particularly when coming on boost, is that one of them will spool up and start producing extra flow compared to the other, which will put back pressure on that other compressor, which will push the operating point on that other compressor up (vertically). This will generally result in it bumping up against the surge line on the map, but even if it doesn't, it upsets the compressor and you get this surging shuffle back and forth between them That is "turbo shuffle" on a GTR. It is related to other flutter effects heard on other turbo systems, but it is a particular feature of the somewhat crappy outlet piping arrangement on RB26s. There are plenty of mods that have been attempted with varying levels of success. People have ground out and/or welded more material into the twin turbo pipe to try to prevent it. Extending the divider inside it works, removing material doesn't. There are aftermarket replacement twin turbo pipes available, and these exist pretty mush purely because of this shuffle problem.

      You can temporarily* use lock collars to keep it in place until you can do the bushes, back the nuts off, slide them in, snug back up. *temporarily is often for ever

      Thanks for the quick reply. To be clear, when you say turbo shuffle do you mean turbo flutter "stustustu" or referring to something else? I had thought they were the same thing. When I wrote the post my intention was to say it wasn't a flutter/compression surge sound. My understanding was that a flutter sound would be occurring when throttle is released, whereas I can keep the throttle in the same position for this noise
