iani Posted August 11, 2019 Report Share Posted August 11, 2019 Before I start grinding, has anyone else experienced difficulty fitting a Phoenix exhaust manifold & a Weber inlet manifold? It looks like I'm going to have to remove some material off the lower edges to allow the inlet to fit. Ian Quote Link to post Share on other sites
RogerH Posted August 12, 2019 Report Share Posted August 12, 2019 Hi Ian, my new (2007) Phoenix manifold would not sit next to the standard TR4A manifold. I had to fettle both to sit right. Roger Quote Link to post Share on other sites
Harbottle Posted August 12, 2019 Report Share Posted August 12, 2019 Hi Ian My tr5 (PI) has a pheonix manifold fitted by previouse owner and you can see were it has been fettled to fit. I had to remove it recently for some work to be done and it was a pig to get back on but managed in the end. Paul Quote Link to post Share on other sites
JochemsTR Posted August 12, 2019 Report Share Posted August 12, 2019 Rework on exhaust and inlet manifold is not uncommon. Just make sure not to take off too much from one, just keep it balanced and ensure gasket lines up nicely with head and manifolds..... Jochem Quote Link to post Share on other sites
Tom Fremont Posted August 12, 2019 Report Share Posted August 12, 2019 I have a Racetorations header ostensibly made by Phoenix and some of the #1 inlet tract of my CANNON Weber manifold had to be ground away to clear it. Same thing happened on the next installation I did, which now has a GOODPARTS 6-3-1 header as the Racetorations left the mid range flat on that engine. No interference with the GOODPARTS, and it really did the trick on the mid-range. Moreover, the main system had to be leaned out 1 main step and 7 air corrector steps to restore the top end performance. Tom Quote Link to post Share on other sites
iani Posted August 12, 2019 Author Report Share Posted August 12, 2019 Thanks chaps, I’ll put some engineers blue on the exhaust manifold offer up the inlet and see how much of a problem I’m looking at. Quote Link to post Share on other sites
