TWM Throttle Bodies Wednesday, September 16, 2009 During the course of planning my engine build, I figured I should look into throttle bodies. I read as much as I could online for quite a while. Finally I picked up the phone and called one of the Miata shops known for their throttle body setups. When I got the answering machine, I hung up. I called several times over the course of a week and continued to hang up when the answering machine picked up. Since Les has been running TWM’s on his Miata-based Locost 7 (Gibb’s “old” engine, I believe), I figured I would give them a call. The phone rang twice before Garry Polled, the owner, answered. I was very impressed with his professionalism, depth of knowledge, and willingness to help. I was pleasantly surprised to learn that TWM’s pricing is actually very affordable. The TWM kit includes a beautiful fuel rail (with quality AN fittings), rail-mounted adjustable fuel pressure regulator, and injectors. Best yet, if I did not want the fuel pressure regulator or injectors, the price fell right in line with the other IRTB setups. These other setups do not include injectors or a fuel pressure regulator, so the comparison is fair. The price net of these items was about $1700, but in the end I sprung for the fuel pressure regulator. I may even have to get the injectors if the RC-engineering injectors I have do not fit. Well, the box arrived today. True to my new photo-geek status, I started taking pictures before I opened the box. All parts were very well insulated and packed, and the throttles, a thing of beauty! The carbon fiber air box? Pure sex. :o) PICTURES: <a href="perma://BLPageReference/A30F32DC-BD66-4CFD-99F6-596C46658C38">Click here for pictures of the TWM ITB AWESOMENESS.</a>
