hey guys, ive posted up some strange threads lately but heres another, im slowly doing up an na for ****s and giggles on a pretty tight budget, heads sorted exhaust extractors etc etc thats all good but then i got onto the intake manifold and i thought hmm what havnt i seen on an rb 30 or something not common and i straight away thought trumpets anyone seen this done ? im looking for some ideas so i can make a set up or if worst comes to worst order some, i personally think its gonna look/sound tuff but let us know ur opinions and ideas guys cheers.. btw before u say turbo it, i already have a turbo calais this is purely a ****s and giggles car lol cheers Some original photos have not been recovered yet.

nah but his trumpets go inside a plenum, i want 6 trumpets, each with a throttle body of there own all connected by a bar so when the throttle is pulled they all open up.. Some original photos have not been recovered yet.

well i dont want the intake manifold open at all times i want it set up so that when i open the throttle all 6 trumpets open depending on the position of the throttle so in essence yea something like that Some original photos have not been recovered yet.

surely it could be done.. RB26's have individual throttle bodys i think. hows this? NA runners, throttle body on top of each runner, trumpets on top of the throttle bodys going through the bonnet! haha.. would be expensive, but possible

I was told of a car for sale last week that is a VL Rally car running an RB30E with 6 throttle bodies. Am guessing it would be a trumpet setup. Corsa

I remember about 8 years ago, some company was making an intake manifold with trumpets and individual throttle bodies for a N/A RB30. Might see what I can dig up.

Obviously an aftermarket ECU would be required because you'd need to make the switch to MAP sensor.

There are kits available to fit the RB26DETT intake manifold to an RB25DET head, so there may be one to fit it to the RB30E head.

sweet guys getting heaps of info yea its not gonna be cheap but still not over the top expensive, i could get pro tigs one but then id still need a lot of modification, if i just made my own from scratch i could make it all to suit Some original photos have not been recovered yet.

start with the gtr throttles then weld the trumpets onto them

Might be easier to go triple carburetors. Not a RB30 but similar
