Im the person who glen put in touch with kings performance.to be fair they were very helpful when purchasing the stage 3.5 turbo kit,but they failed to mention that I needed an oil filter relocation kit,so a week later that turned up.then after further inspection of the kit,the boost pipe was misaligned when welded and the weld didn't meet.also the screamer pipe has snapped 3 times.ive had a new one fabricated,and it's been fine since,also the turbo oil feed fell to bits,luckily just after the mapping session and not during,new custom oil feed purchased/fitted and puts original oil feed to shame in quality.
I also got in touch with kings about a t4 .58 exhaust housing,they said they can get me one,so emailed them back several times and got no response,after a week and half I gave up on them.
To be fair the problems I experienced are easy fixes.but some of the kit is cheap and not acceptable.the exhaust manifold,turbo,intercooler are the only decent parts from the kit.
So I've replaced the not so good parts with quality parts and I am now happy with kit.
Just wish it was that easy for glen.after the money/time he's put in I would have certainly broke the car for parts and called it a day.
I'm sure it would be a different story if kings were based in the UK.
