I had particular interest in TWM's because we use these for our Honda street/strip motors. But I am a little concerned because of angle on the TWM ITB's for the Miata where it seems to be a 90 degree angle. I don't know how that would affect the airflow in to the head.If you've got a 1.8 I think TWMs are the best looking (for the money) since the throttle body is integrally cast with manifold and the linkage is anodized and real pretty.
Is the above what you have used or are you suggesting it?
I have a friend/mechanic/owner named Jerry Guzman at Jerry Built. He has access to a very good dyno and he can tune for me as long as I have the software and equipment. He currently dyno and tunes Hondata for Honda B series and K series. So hence the reason why I looked in to Maruha's also. I was thinking that I can purchase the software and equipment and do the tuning on my motor first. And if other members decide to go with Maruha's later, I can provide the software and tuning and just charge you a minimal fee.
Are you referring to the 1.6 kit? That's what I heard, but I agree with Bryan that every motor is different in e.g. headers, cams if any, motor work, etc. I'm not too sure about that it being plug and play.I was under the impression that the Fuji Racing kit with the stand alone ECU, it is basically plug and play. Am I wrong?
I guess thats why one has to do it one time and do it right.With IRTBs there will not only be tuning, but constant fiddling and adjustments.
This is a huge assumption on your part that you are wrong on - with a correct and proper ECU (like my F-con), I never have to fiddle or adjust to keep them working. It starts like any other car - works fine in the hot and cold and at higher elevations. It is very stable and it is quite easy to install - it is the tuning when set up correctly, that will give you years of trouble free operation.With IRTBs there will not only be tuning, but constant fiddling and adjustments.
