A 26 head is not a cheap option! Try Extractors and K&N panel filter first. Maybe a couple more deg. timing and/or Adjustable cam gears.

thanks do u have any prices on the parts and the name of the parts i should be after???

and would a rb26 head give me better performance or not really,

i have a k&n pod filter and a and i have a cat back exhaust system, and an exedy heavy duty racing clutch... also would getting a better cat improve performance?

dont know what brands to get, but extractors, cat, cat back exhaust, replacement panel filter, maybe even chip the ECU...

dont bother with the RB26 head, it probly will give you minor increase in performance, but last time i saw an RB25DE head was worth about $1200, so im guessin an RB26 one would be around the $2k mark, if not more?

so about the ecu what should i be asking for? and what will it give my car performance wise...?

also can anyone give me info about a new cat for my exhaust kit?

would a high flow cat be worth getting??

jeez man - play 20 questions hey.

there's a thread just below yours with RB30 power increase (or something similar) - the principals are pretty much the same have a read through that. also try a search in the NA section there is a plethora of information here.

there is an extractors thread which discusses alot of exhaust mods, along with prices and names.

a better cat will give increase in performance in both power and driveability.

it's pretty obvious you lack the fundamentals of how things work and what not. it's my suggestion that you have a read through/search some of the older threads to get cluey.

well im sorry i cant sit here all day and read on the computer i do have a l ife and things to do, i asked my question and left... i didnt have time to sit and read when i posted that when i got back i had a reply...

sometimes different actions need to be taken in life.

sorry for using ur forum if it bothered u that much

no its not my forum... and i'm certainly not telling you what to do, but there is a thread pretty much on par as to what your talking about.

it's just the general etiquette here... but no one is stopping you, i thought i'd just pass on what was told to me. there is however a fine line between being lazy and genuinely clueless.

Someone spoon feed me...

just do the standard mild NA mods.

leave the head, free the intake, exhaust to 2.25 or 2.5, get a tune (or cpu)... and get a handling kit. No sense going fast if you can't turn.

  • 3 weeks later...
on yahoo at the moment

so yeah what was it about the engine u posted the pic for?

also i need to buy a new rb25de atm so if anyone has a decent/reconditioned cheap rb25de i would like to know how much u would be after...

Here's a little tip that might help when on a budget, the factory turbo exhaust systems are a bigger bore (2 1/2") than the factory N/A versions if you look around you might be able to find a cheap 2nd hand turbo factory system, slap it on an N/A and instant exhaust upgrade :wave:

Another thing ECU's are expensive and so is the tuning (I'm running a GTS link in my R33) and don't give you that much more power they just give you a heap of potential later on for more mods.

As opposed to other people, who apparently have the time to sit here and answer inane questions by you and your kind for the upteenth time because you guys can't be bothered doing any research?

Great attitude.

Most people aren't here to lecture on Car Modifications 101 to people, especially when its already been explained a million times before. They're here to learn new things, and only when they can't find it will they go and ask.....so other people with the same questions in the future can find it down the track.

If you don't care enough to actually go and look, then I'd say you don't care enough to go and modify your car. Why not go buy yourself a Corolla, don't worry about getting into the car modification culture, and just go "have your life and do your things"?

But, if you want to know how to shave 2 seconds off your ET in a NA vehicle, with almost no cost, then this article from Sports Compact Car should be your guide.

well said scathing.

and for your information, that there looks like a fully worked NA RB motor, with cam gears, individual throttle bodies with a custom looking adapter, and trumpets, extractors and an R32. what from first glance looks like a serious piece of machinery!!! nice find 1400R

i'd expect that it'd have some internals done.

thanks Eug I thought I was helping showing what a rb na built for power looks like

for those that are interested

"HSK exhaust and manifold, no cat straight 6 connected throttle funnel specification, ported head

F con V professional ecu, bucket seat, 9 point roll cage F/R strut braces, carbon bonnet"

I edited the translation a little to make more sense I hope

car looks phat to

Edited by 1400r
hmm there is some motervation back at my hex throttle conversion

DO IT!! dont be a pusseh :P:):);):)

nice work with the translation 1400R

had a look at his description doesnt look like any internal work done... i'm disappointed.

still a 2.5L hex throttle with a decent exhaust, and cam gears and decent tune. compared to my car which makes 108rwkw stock (dyno dynamics) i'd guestimate somewhere around an easily 140-150rwkw.

and sitting in a lighter r32 chassis!

    • Hi, is the HKS  Tower Bar still available ? negotiable ? 🤔
    • From there, it is really just test and assemble. Plug the adapter cables from the unit into the back of the screen, then the other side to the car harness. Don't forget all the other plugs too! Run the cables behind the unit and screw it back into place (4 screws) and you should now have 3 cables to run from the top screen to the android unit. I ran them along the DS of the other AV units in the gap between their backets and the console, and used some corrugated tubing on the sharp edges of the bracket so the wires were safe. Plug the centre console and lower screen in temporarily and turn the car to ACC, the AV should fire up as normal. Hold the back button for 3 sec and Android should appear on the top screen. You need to set the input to Aux for audio (more on that later). I put the unit under the AC duct in the centre console, with the wifi antenna on top of the AC duct near the shifter, the bluetooth antenna on the AC duct under the centre console The GPS unit on top of the DS to AC duct; they all seem to work OK there are are out of the way. Neat cable routing is a pain. For the drive recorder I mounted it near the rear view mirror and run the cable in the headlining, across the a pillar and then down the inside of the a pillar seal to the DS lower dash. From there it goes across and to one USB input for the unit. The second USB input is attached to the ECUtec OBD dongle and the 3rd goes to the USB bulkhead connected I added in the centre console. This is how the centre console looks "tidied" up Note I didn't install the provided speaker, didn't use the 2.5mm IPod in line or the piggyback loom for the Ipod or change any DIP switches; they seem to only be required if you need to use the Ipod input rather than the AUX input. That's it, install done, I'll follow up with a separate post on how the unit works, but in summary it retains all factory functions and inputs (so I still use my phone to the car for calls), reverse still works like factory etc.
    • Place the new daughterboard in the case and mount it using the 3 small black rivets provided, and reconnect the 3 factory ribbon cables to the new board Then, use the 3 piggyback cables from the daughterboard into the factory board on top (there are stand offs in the case to keep them apart. and remember to reconnect the antenna and rear cover fan wires. 1 screw to hold the motherboard in place. Before closing the case, make a hole in the sticker covering a hole in the case and run the cable for the android unit into the plug there. The video forgot this step, so did I, so will you probably. Then redo the 4 screws on back, 2 each top and bottom, 3 each side and put the 2 brackets back on.....all ready to go and not that tricky really.      
    • Onto the android unit. You need to remove the top screen because there is a daughterboard to put inside the case. Each side vent pops out from clips; start at the bottom and carefully remove upwards (use a trim remover tool to avoid breaking anything). Then the lower screen and controls come out, 4 screws, a couple of clips (including 3 flimsy ones at the top) and 3 plugs on the rear. Then the upper screen, 4 screws and a bunch of plugs and she is out. From there, remove the mounting brackets (2 screws each), 4 screws on the rear, 2 screws top and bottom and 3 screws holding in the small plates on each side. When you remove the back cover (tight fit), watch out for the power cable for the fan, I removed it so I could put the back aside. The mainboard is held in by 1 screw in the middle, 1 aerial at the top and 3 ribbon cables. If you've ever done any laptop stuff the ribbon cables are OK to work with, just pop up the retainer and they slide out. If you are not familiar just grab a 12 year old from an iphone factory, they will know how it works The case should now look like this:
    • Switching the console was tricky. First there were 6 screws to remove, and also the little adapter loom and its screws had to come out. Also don't forget to remove the 2 screws holding the central locking receiver. Then there are 4 clips on either side....these were very tight in this case and needed careful persuading with a long flat screw driver....some force required but not enough to break them...this was probably the fiddliest part of the whole job. In my case I needed both the wiring loom and the central locking receiver module to swap across to the new one. That was it for the console, so "assembly is the reverse of disassembly"
