Whne I was in JApan I picked up an HKS Super sequntial Blow off valve. The instrustions are in japanese. Does anyone know how to take this BOV and put it on my 1993 twin turbo. I know that the reciculattion valves would be replaced but how would you replace two valves with the one BOV?

You only replace ONE. The valve to the rear is the Charge Relief Valve. Replace the front valve with the new BOV.



Any reason you chose to replace the valve in the first place?

well, hopefully you got the kit for the rx7 and not the universal one. if you did NOT get the kit, there is going to be a mounting problem, and the fact that the universal kit does not come with the firewall mounting bracket, because it is intended to be a weld-on application. there will not be a flange/hose adapter on that model as well.





as far as installing it, there are 2 or 3 pics right? just remove the old one like 9base3 said, and slide the hose onto the flange piece that the bov comes with and run the vacuum line from teh manifold to the small nipple on the underside of the BOV itself...



hope that this helped

I was going to change it because it sounds cool.

well, did you read my post? or are you just thinking about how it sounds....i have installed about 3 of those.....but oh well.....

The kit is actually for a sr20det nissan motor. Should I sell it on ebay and get the RX-7 kit? THat sounds like a stupid question but I could use the BOV and make my own bracket.

Would this Bov be of any benafit other than the sound effect?

well, the stock one is fine, for most, and as far as the pitch, i think that the ssqv like you got is the best.



if you got it for a nissan, there is most likely going to be install problems as far as the mounting and the hose fitments. if you have a mostly stock car, this unit really will not affect you, unless your stock BOV is defective.



the issue that you have will be the overall pplacement of teh valve itself. when you purchase a 'universal' kit, you are getting a stripped down version of the unit that comes with no brackets and stuff, and that is because it is meant to be welded onto the intercooler pipes....that way, you can eliminate some hoses and clean up the ehgine bay a little. also, since the valve will then be directly mounted to the intake air tract, the response will be better...

Thanks for the info. I think I will sell the one i have and pick up the correct kit for my car. I don't want to do anything half ass.

how much do you want fo it. i tell you. i have an apex'i twin chamber BOV on my car, and it IS the kit. i would swap you, and add a little money of you wanted. i have been looking into selling the apex'i one as of late to get another hks one.....let me know....i also have a greddy bov for the fd at the shop. i can sell it too....



pm me if you are interested.....
