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

    • Yeap, not as doorty as ITB's, but alot more doorty than before, induction sound great when I'm up it 🤗
    • Any difference in induction noise?
    • If I got a dollar for every flipped commuter missile I've driven past I'd have two dollars   Some people get into wild adventures on the road and I doubt it's gender or ethnicity specific. I'm just glad I don't usually drive during peak times.
    • Just got the car back and gave it a good run back home Power wise, whilst it only made a extra 5 killerwasps up top at 7200 rpm, it made more power everywhere from 2500 rpm and kept pulling much harder all the way, to the point of me relearning when to shift so I don't hit the 7200 limiter, with the old intake it seemed to take alot more time to rev out, and, throttle response is also much improved  As I didn't want to remove the bumper every time I serviced the air filter (basically every aftermarket and fabricated CAI has the filter behind the bumper) it currently has a hektic exposed pod in the engine bay sucking in hot air, this will be rectified shortly after some some of my CAD (cardboard assisted design) for a alloy heat shield feed by the OEM intake tube behind the bumper, this will cop some wrinkle black paint, as well as the intake pipe for that totally OEM look... The only fly in the ointment was that the OEM "strut" brace doesn't fit over the rear runner of the new intake with the 2.5 engine is in the engine bay, as the 2.5 raises the engine up by 20mm, it's not a war stopper, and I didn't notice any difference without it in some twisties, but....... MX5 Mania is bringing in some GWR "fancy pants" braces that apparently do fit, if it bolts up I'll grab it, it is also stiffer than the OEM one, which is a bonus All in all I'm happy with the outcome      Fancy pants "strut" brace that gives the required clearance      This is where the clearance issue was, the GWR extends out past this
