SORRY FOR LATE REPLYS

how do you get it nice and big and round? what did you use to shape the sheet? im assuming u started with aluminium sheet?
looking at it, it was a half tube for the round section

hammer and doly or english wheel for the other bends ..

please correct me if im wrong though

its a half tube with sheet metal welded onto it, its welded on both sides so that i could remove the welds on the outside with out the plenum leaking

Wow, nice man! lets see some number when you get them. Noticable gains or what? if you ever start selling them i would buy one off ya. good job

i do sell them

wat 180 :S ?

the rb has found a new home in the engine bay of a 180sx

ok so i was wondering about one of your plenums for my rb25/30 combo the main reason i want one is to solve the bonet clearance issues that the stock intake manifold has. ill be aiming for around 300rwkw and was just after a price and also was wondering does it use the stock throttle body and cable and also where does all the stuff like your acc valve (idle control) and the rest of that stuff go vacume hoses ect thanx in advance i will be looking at getting one in the near future so hope you can help.

Saw you post this link in a thread. Do you actually have any real world results from cars. I have a std RB20 which needs a little help making a bit more power. Dont want to lose any mid range torque though...and my fear is moving away from the long std runners will hurt me in the mid range? Any experience with different RB20 setups? Im running a TD06-20G making 260rwkws on 18-19psi

^^^ as above, lets see some before & after dyno sheets showing no loss of midrange.

Shaun @ Boostworx has even seen a RIPS plenum hold back peak power over the stocker - so after hearing that i need real world results before money is parted.

      R34 engine swap Rb25de neo to s1 Rb25det

      By GTSBoy · Posted

      THERE IS NO IAT SENSOR ON ANY SINGLE TURBO RB. And the one on an RB26 is not for "engine control" - it's really too big and too slow and is only used for over-temp alarming (as far as I can tell). Anyway, you don't have one. You want/need one for the Link, then you need to buy one, find a spot for it, and wire it in. You do know that the stock boost solenoid is not capable of "control", right? It is merely on or off, for the low boost (5 psi) and high boost (7psi), which the ECU enforces mostly based on gear. The stock solenoid is not for PWM control and is not plumbed up in a way to provide it. If you want to control boost properly, then you need a proper MAC valve. And yes, you can wire either of them direct to the ECU. Well, I assume you can - I don't know what the boost solenoid pins on the plug and play Link are capable of. They really should be as capable as any normal Link - but seeing as it is plg and play, it might be limited to stock functionality. Read the doco.   You really do just want to plug stuff together without understanding how it works, right? I can't help you there. I don't know the plug types or pinning on half the stuff you're asking about. If I had to do it I would sit down with the wiring diagrams, the car/looms and a multimeter and work out what is what.

      Factory oil temp sensor in a RS4V without gauges?

      By GTSBoy · Posted

      Light should be a pressure switch, not a sensor.

      The pressure light likely has a different sender to a pressure gauge, its been too long for me to remember for sure. Just have a look for another sender down near the oil filter. If you are confident in your rewired pressure sender reading correctly, you can be pretty sure it is just the dash light's sender failing, it is a pretty common thing.

      S1 headlights?

      By Duncan · Posted

      That is a series 1 front end (grill, bumper, headlights). I'm not sure if you are trying to confirm if your whole car is series 1 or just the headlights, but the build date and vin# on the plaque in the engine bay would be the best reference for what it was when it left the factory (noting a lot may have changed over the years)
