Hello i have a d15b7 with a t3 turbo and i running a safc with 450 injectors, i was looking into putting a vtec head on with a turbo cam. Two things could i run the safc or would i need a vafc, and would i have to buy a bigger fuel pump

 

you can keep the safc but you're not going to be able to tune the v-tec engagement point like you would be able to with the vafc. you'll be ok with the stock fuel pump depending on how many miles are on it. i would go with a 255 pump just to be safe however. you usually only need a stronger pump for fmu set ups but its better safe than sorry and your stocker probably already has over 100,000 miles

 

thanks ya my pump has over 100000 miles on it. any more opinons are very welcome

 

well heres the thing you can tuning well with a Safc, but if you have vtec i would definitely use the vafc because then you can control low and high (vtec)cam maps that way, so you would be a better tune for vtec crossover point + also change the vtec crossover if you wanted to, Safc doesn't have the high and low cam feature so you would only be able to tune to a certain extent.
For the fuel pump not totally sure if you have to change it or not, but i guess it would be a little more reiable to change maybe to a 255 walboro, its really up to you...450cc injectors help fuel flow anyways
