Not really - £189 per unit with free postage. Jenvey DCOE 45s are £242 NOT including VAT or shipping, and they don’t include the fuel rails, which are £38+VAT each for the short individual ones as per the FAJS ones (that’s what the Sherryberg ones actually are). That’s quite a meaningful difference when all added up.
The FAJS ones are essentially knock-offs of the Jenveys - let’s get that out the way first. However, having got a set of them, I see nothing that would suggest lesser quality in machining, function and reliability (maybe the exterior castings aren’t quite as pretty as the Jenveys). As I said, all the Jenvey official parts fit on the FAJS - thus, one can make use of Jenvey’s nicer AN- fitting fuel rails and linkage options. If budget is a factor, then I consider the Chinese ones contenders. Married to a Harada manifold, you achieve a good setup for much less than what the Jenvey equivalent costs.
Optioning up the L-series complete kit on the Jenvey website is absolutely eye-watering IMO. Convenient that they sell it all, but damn…
Do like the Heritage ones though!
