Great service. Great support. Turbo whistles sweet sweet music.
I keep coming back to BSI for clamp and flange kits, They are about the best clamps and flanges on the market for an awesome price. Highly recommended!!
Worker great
These flange kits fit perfectly and the clamp is very durable!! The flip style T-bolt quick release is awesome as well. I use them for a disconnect on the downpipe for compound kits, makes it very nice for removing the downpipe to work under the hood.
This drain works as it should. I do however see an issue with the bolt hole size could be drill closer to the bolt size being used. This would aid in centering the o ring on a turbo with a narrower mating surface. I was able to smget it centered. Its a great product. For a 8 mm bolt the hole needs to be drilled for an 8 mm hole. The 10mm hole gives too much movement when centering. still 5 stars on the product
Purchased an 85mm turbo for my truck after burning up two vs racing turbos in a 2 week span.
This turbo has taken a shit kicking and works incredible. Just made 855 whp on my little 5.3.
Nick was also amazing to deal with. In stock, ready to pickup. Even went through my old turbo for me on his own time. Will always have my business 👍
Fits perfect! Allowed for a nice large return line that’s leak free!
It’s a shame this isn’t seen once installed, it’s beautiful! Oh and don’t be an idiot, on a smaller turbo you gotta tilt it to get it in place when installing it but it still installs flat. I can’t believe people complain about that, lol.
I’ve had one on my rotary for a few years now. Regularly sees EGT’s near 1000c and a glowing turbo. Not only does it keep the temps down, it doesn’t crumble like the cheap ones when you remove it to service things. Bought another for my next build.
I have bought T4 S400 turbine outlet flange kits from a couple different suppliers and these are the best I have found, they have a ridge that slides into the turbine outlet that helps to center it and holds it there - very nice!
Very nice quality, turbo makes great power and pretty responsive for a s472 highly recommend a true north turbo!
Very nice quality, bolted right up to my gt55 turbo with supplied hardware.
