MJ.rusty Posted October 12, 2009 Posted October 12, 2009 heard somewhere u can put HO (91-93) headers on a renix. just wanted to make sure before i make an expensive oopsy.
cracker Posted October 12, 2009 Posted October 12, 2009 heard somewhere u can put HO (91-93) headers on a renix. just wanted to make sure before i make an expensive oopsy. It will bolt up but the ports won't match. Run the HO head too ;)
Geonovast Posted October 12, 2009 Posted October 12, 2009 You'll need the HO downpipe too, or you won't have anywhere to mount your 02 sensor.

It may depend upon the manufacturer's design, but Borla's HO and Renix headers appear to be the same besides the EGR. Renix on bottom, HO on top. Willy
MJ.rusty Posted October 13, 2009 Author Posted October 13, 2009 Any idea how to run the egr on the HO borla headers?
cracker Posted October 13, 2009 Posted October 13, 2009 I may be wrong. :doh: It is the intake that doesn't match. Sorry.
reson46 Posted October 13, 2009 Posted October 13, 2009 Any idea how to run the egr on the HO borla headers? Find a bung that matches the threads of the EGR tube and weld it to one of the header tubes. Borla put it in the tube for cylinder #5. You can see it on the bottom one here. Willy
reson46 Posted October 13, 2009 Posted October 13, 2009 I may be wrong. :doh: It is the intake that doesn't match. Sorry. I used to think the same thing. I had always read that the ports were in different locations, but never paid attention to if it was the intake or exhaust ports. I just always assumed both were different and never paid much attention to it until I had the HO and Renix Borla headers side by side and noticed they looked exactly the same. I will also say that I don't know if this is true for all brands, only Borla that I know of. I don't remember the specifics, but I think it was Jeepcomj that had clearance issues between one of his header tubes and the intake manifold he was using. Willy
Geonovast Posted October 13, 2009 Posted October 13, 2009 Any idea how to run the egr on the HO borla headers? Eliminate the EGR. Plug both holes, and disconnect the relay for the solenoid.

Willy Yes, the Borla header has known clearance issues when using the 1999+ intake manifold, but correctable by grinding some off the manifold.
MJ.rusty Posted October 14, 2009 Author Posted October 14, 2009 Would it run ok or even pass emissions if I plug the egr?
Geonovast Posted October 14, 2009 Posted October 14, 2009 It'll run just fine, they did away with the stupid thing in 91 anyway. As for emissions, depends on your state/county.
MJ.rusty Posted October 14, 2009 Author Posted October 14, 2009 Well I'm from pa. Not cali so maybe it will pass. Not sure
