EFI Throttle Body Comparisons
There is a bunch of info on these different throttle bodies; but it would be nice to have some concise comparitive info on them.
http://www.eastcoastparts.com/assets/images/TB104.jpg This one http://www.efihardware.com/efi_throttle.html And the one dj55b is using https://www.rx7club.com/1st-generation-specific-1979-1985-18/fuji-racing-itbs-finally-d-683967/ I plan on using one of these and I would like some info/advise. My plan is: 12a streetport with RB exhaust then upgrade to turbo. It would also be nice to be able to swap this throttle body into a 13b then turbo it. My thoughts/questions are: The first one looks kinda big for a 12a NA - comments. The second one looks great but I kinda like the sidedraft. The third one only had two injectors - not enough for a 13b turbo? What are the HP potentials of each? Like I said, lets discuss the advantages and disadvantages of each setup with respect to the other ones. |
if you can afford to support the first one, go for it. since you listed plans for a 13B Turbo after your 12A setup, i think it can work well with both. i like the IDA style stuff for N/A application of all porting styles and DCOE style stuff for forced induction. however, that 4-barrel style throttle is questionably more versatile. i don't know. i'm building a 4-barrel setup right now, so i'll be able to draw a more solid conclusion when it's up and running.

Just that peiece alone and everything involved to run it correctly isnt cheap. As far as more info your better off posting in the "Race car/drag racing" section as this isnt a common set up for 12a's.:icon_tup:
