Just adding to the mountain of praise on here for Jim, but I couldn’t not drop a review after the work he’s just finished on my Z32.
We all already know Jimmer is the go-to guy for these cars, but experiencing it firsthand is something else. He has given the car a completely new lease of life. That rough idle is entirely sorted, and with the new injectors and new loom in, it honestly runs just like it’s come straight from the factory.
His insight and attention to detail live up to every bit of the hype on this forum. Communication was top-tier throughout, the turnaround was incredibly quick, and—as everyone always says—it was very well-priced for the level of specialist expertise you’re getting. Jim even checked in with me after I got the car back to make sure it was still running perfectly.
Safe to say he’s found another return customer in me; I'm already planning the trip back down to Bristol next year for some new turbos.
Just adding more reinforcement to what this community already knows: if your Z needs sorting, @jimmer is the man!

Hi guys, I thought I'd post this discussion I had with Jim at JWT and SGP last night, about what my next options are after my AVC-R install...
(yep - it's cut for an email to Viking)
Feel free to comment, correct me, hang me, shoot me as required.....
