i ordered an professional products whirlwind (aebs) intake manifold for my 97 gsr. i will not be using on of the large vacuum fittings on it beacuse i will be running a catch can and eliminating my pcv. so my question is can i run a vacuum block off of the unused fitting on the intake manifold?

also im debating even running a vacuum block, could i just run a line from that unused fitting on the intake mani and T it to go to my electronic boost gauge and waste gate and T a smaller hose off the intake mani to run to my hks ssqv?

 

Does your turbo have a bung in it for a vacuum line? That is the best place to run the wastegate IMO. But yes, you can run vacuum off of that port.

 

so i run can line from the port and T it to the gauge and wastegate?

 

yes you can use the unused port to run your accessories. you might get away with tees but a vacuum block will distribute things more evenly and give each item a dedicated line. it will probably also look cleaner than teeing

also an aftermarket IM should have plenty of extra vacuum ports anyways so you may be able to use them. for example my victor-x has all of these ports on the bottom of the plemun

 

what vtechjunkie is suggesting is that if you have a fitting on your turbo compressor housing then you should run the wastegate to that. the wastegate does not need to see vacuum, it is operated by boost only. vacuum can actually be harmful to the diaphragm

 

i do have a plug on the turbo housing. its an sc61 where can i get a fitting for it?

 

any hardware store. 1/8" NPT

 

thanks i think ill be running a line from the turbo to the wastegate. and the boost gauge off that extra vacuum port on the IM.. any recomendations of where to T for the hks bov.. its a small vac line

 

anywhere on the im between the tb and head. bov needs to see vacuum when the throttle plate closes.
