to cut a long story short i was talking to a guy today who makes up custom bits and bobs for cars and motorbikes some of his work has gone into a few cars that have featured on the front page of magazines so i started talking to him about making me up a front entry plenum up but not using the standard one on a gtst is it going to be worth it and is there anything to watch out for if i start making one up?

Have a search dude, there has been a lot of talk about this in the past and some useful information spread. It's quite easy to fk up the air flow though so do a lot of research before you commence.

Not really worth the effort in my opinion.

There is a lot to consider and a hell of a lot of flow testing and R&D that goes into any efficient plenum design.

There are plenty of options already available, Greddy and Plazmaman being the two most popular/common.

I tend to agree with Blitz. plenum design is pretty important and a bit of a dark art to get it right. there are some good off the shelf products out there as nick mentioned that are not prohibitively expensive.

thanks for the comments i know what your saying about flow testing and that i am after a one off pice and in the uk gredy and plaman one are quite expensive £500+ the guy who might be helping me fabricate it in heavily into motor racing and has made inlets up before for high spec cars just not skylines thanks for all the inlet pics im shore they will be very handy if i do decide to do this

    • Block bump. $400. As above cyl 6 needs bore or sleeve.
    • I would think making the argument that the travel is limited by a spring flexing against a spring perch as "the same method". Later on in the document they do state that the spring can't bind on full bump travel and cannot come loose in full rebound travel as well. (which is all very sensible). The laws are actually pretty sensible and reasonable. It's just that the people who enforce and check them don't actually read them or know them accurately. "Oh, coilovers? Instant fail mate. Don't even need to look at it." - Guy who will be instantly reported by me. There is probably merit to people who do get defected for height also get defected for the suspension in that state that allows it. I did never consider the people who are complaining about coilovers being picked on are also running around at 50mm off the floor.
    • I think given SAU's knowledge of E85 we can strongly conclude that 10% ethanol in almost any situation is entirely fine. Almost all of the myths against E85 were overblown, let alone E10.
    • From your link See bold text, is this referring to damper settings, if so that may a issue for "some" inspectors, I cannot see aftermarket coilovers having the evidence that "must be available that its functional performance is equivalent to the original" Maybe just remove the adjustment knows and hope for the best???? Meh 5.2 Suspension travel In all instances, modifications to a vehicle’s suspension must ensure the integrity of the system and not compromise the ride quality. At least two thirds of the original suspension travel should be maintained in both directions (rebound (i.e. extension) and bump (i.e. compression)), and rebound must be limited by the same method used by the vehicle manufacturer or if this is not practicable due to the nature of the modification, an equivalent method. If an alternative method is used, evidence must be available that its functional performance is equivalent to the original.
    • They actually don't - They adhere to VSB14 rules just like Victoria. The rules are against CABIN adjustable height, and it quite clearly states that the height has to be within parameters. I asked the VASS engineer to confirm this when I got my car engineered and they refused to engineer the coilovers because they didn't meet the requirements for requiring engineering. (mine are height adjustable.) People "Not wanting to bother" with "Actually reading/knowing/adhering to the rules" should result in fines and immediately losing the ability to issue blue slips and/or RWC's in Vic.
