Hey guys,
just wondering if anyone has had a go at making quad throttle bodies for the dohc ZC. I found a step by step guide on how to make some 4 a b16a from 4age 20 valve throttle bodies and thought it mite be worth having a go. I work in a engineering workshop with a laser cutter so making the flanges etc wont be hard. the main problem would be using the toyota TPS and injectors.
I dont want to fork out the money for some aftermarket ones as im on a tight budget (apprentice) so im looking for bang for buck. this is to go with existing cam, head and exhaust mods.
any comments would be helpful.
Cheers

yes, it has been done many times - most people use the Honda motorcycle CBR929RR throttle bodies (38mm) since the TPS is compatible with the Honda ECU
