Having trouble with my Turboxs RFl's

[s13drft89]

Hello,
So i purchased my rfls from z1 as a kit. Everything was installed properly and checked and rechecked. Im getting a little compressor surge at low rpms. Though when I drive the car hard it blows off fine. 1st and 2nd is the only gears I can hear them blow off. 3rd 4rth and 5th all I hear is compressor surge . I removed all the washers from inside. and checked for all leaks. Im getting good vaccum to the bov's. The car idles fine. Im not sure if these are made for higher boost application, but Ive seen these on stock wrx's and 240's running fine. For mods I have full exhaust and an intake. I have them to atmosphere not recirculating. Thanks please any input would be great. Would it be possible that i need to put them closer to the throttle body????? Ive seen z32's with hard pipes from the throttle body to the black tube leading on the side of the radiator?

Any ideas??

I tanked a turbo due to a cheap bov, I don't risk my turbo's with cheap bov's, the stock valves work great and handle lots of power, you chose a noise over performance and reliability, you might want to reconsidder your choice

Little fyi i haved them hooked up to recirculate. My choice in the car I want to drive is very much made up. Thank you for the input that had no relevance to my issue, that did not even come close to helping me. I will be returning the turboxs's and getting a refund.

Problem: cheap bov's not working properly

Solution: don't run cheap bov's

That better?

I did not critique you choice of car, I was eluding to all the rice boy's that what the whoosh sound of an atmospheric bov even though it actually hurts performance on a metered air engine management system such as the z32, and the cheapo bov being less reliable than the stockers

if you want to run aftermarket bovs don't go cheap, if the bov fails to open that compressor surge can warp the shaft on the turbo, I should know I've done it, I run a tial atmospheric on my Z31 (running megasquirt so it's no longer metered air)

Z1 Turboxs's are cheap blow off valves?

They are cheap cost wise and they are cheaply made, yes. I had them also and got rid of them 2 months later only to return to stock recircs.

2nd this. The stock Nissan recircs are a very sensitive well engineered item that optimizes pressure relief and re-spool time when the throttle is reopened. Up to a huge power upgrade they are tough to beat.
