I'm finally at my highest point in my build - that i think personally and ready for an ultimate upgrade - sports injection - or ITBS to those who dont know the technical terms. I've seen many types of sports injection system - TWMs itbs, Toda itbs, Tweakit Perf. and other DIY types. What i'm wondering is what i should look for in ITBs. TWM has a very short velocity stack compare to tweakit performance itbs. TWMs have a long runner, Tweakits and Todas/OBX don't. Which one is better - I'm aiming for midrange to 11k rpms and will be running AX most of the time. I've personally seen TWMs run low 9s consistently on the drag strip but have seen Todas with very good outcomes on the AX track. I havent seen much TWMs on AX but they seem to put out a lot of power on the dyno on the high Rpms and good torque curve. From what i've researched, it seems like TWMs are the way to go but I would like peoples' input. Please no BS replies. I've done a lot of tuning myself and I would like true inputs on this topic because I've not tune many itbs

There are only two dealers for Jenvey in all of the US. and I have seen Mac @ emerald do setups for all kinds of cars including hondas and these things make crazy power.

 

FYI, Sports injection is what Toda likes to call there complete individual throttle body packages. The technical term for them is still throttle bodies. And they are individual so therefore they are individual throttle body intake manifolds aka ITBs.

Anyway tech names aside, In your brand name list you forgot to mention Kinsler, who have been working with fuel injection and making intake manifolds and individual throttle body setups for quite a few years. Give them a look c if your still in the market. They have a few nice accomplishments posted on there website.
