Subject: Ida style throttle bodys (suit 13b)
I just joined as I am building a peripheral ported 13b rotary and plan on using twin 60mm throtle bodys. I am looking for well priced good quality items or some sort of design that i could make my self. Anyone made there own throtle bodys? This would be my first fuel injected setup so I dont have alot of knowledge on the subect but what i do have is machining experince and the a workshop. Please tell me all that you can in simple terms.

Probably not - these beasts flow a lot of air at full output. Being peripheral ported, he's not going to be idling much below 2K or so anyway. Also, MAPdot can be made to handle situations like this quite nicely (with a little work and examining logs). I've 25K street miles on a street ported 12A w/ 2x50mm TBs and there's zero problems with tipin. Yes, you do get a very non-linear pedal at low load but it's manageable and well worth the high load reward -)ptegler wrote:Aren't twin 60's going to be a bit big for a 13b engine? It seems like off idle would be really touchy with such large bodies

To the original poster: if you're handy with machine work, you might be able to do something adapting one of the GM LT1 aftermarket TBs. They make them in 58x2 and are usually 250-300 on eBay, I have no idea how much new.

There $395 aus brand new but then i got to thinking that i could make them. But before i go spending a few late nights at work I think i'll look into the Nissan ones 510rob mentioned, might save me a bit of stress.

What do you have for a manifold, out of curiousity? So many questions, thanks for starting this thread.

There you go. I realy have no idea what brand they are or if they come in smaller sizes. It sorta looks like thats what i'll be using but i'll see how busy work is over the next few mounths and if it slows down i'll just make some up
