I have not herd of any issues with Sasha's BP kit. The people who have it love it. You call he picks up the phone. If there is a problem it's addressed.
Vortec/SNR/VSR has a bad track record in Tampa. Desperately trying to clean up there rep. New CNC machine, New benders, hired new fabricators, Jiggs for there kit. Starting to get some consistence from them. 1st few kits i was there for tune and was seriously wanting this kit but welds look like 3 year old made them. 4 years later they have gotten much, much better.
If you do VSR kit call Motion Lab and ask what you will need to make it a solid high quality kit. They have some recommendations. They might have a perfected tune they can send you. They have done magic on that kit. VSR did the hard stuff, Motion Lab takes it to next level and fine tunes it.
My 2cents / I live here and see there kits and talk with guy's at shows that have them in 370z & 350z. Most are happy, more than a few are not.
Quality of BP and Sasha's reputation does it for me, he just needs to build an AT Kit for me
