Atlas / Vortec 4200 T4 with divided single 50mm wastegate!
Not one person asked for this! BUT, I think this engine has not received the attention it deserves.
We have been working with @nivlac57 and @motionautotv. The 4200 Straight 6 from @generalmotors was released in a Blazer, but the ability for this engine to hold itself together at now over 700whp through an auto has been documented by Calvin over at the Nivlac57 YouTube Chanel. We have designed this and tested on a number of chassis to allow easy fitment in LHD builds. This has been designed to accept up to the larger frame @garrettmotion G45's, @precisionturbo 75's and 85's as well as @borgwarnerboosted S400's. Again we have machined the manifold to suit a @turbosmarthq 50mm wastegate, but can run a 60 if you cut the flange off (as the runner is designed to flow the 60).

Pricing TBC!

Fits like a glove, looks like a million!
Size: Small, Color: Purple
Bought this as a gift for him and very impressed. Looks like a million dollars, fit true to size, looks tailored not cheap. Fabric is quality, stitching is done well and the pants have a nice hidden elastic extender that helps if he goes up or down a few pounds. Very impressed!

It was the perfect suit for our big day!
Size: X-Small, Color: Purple, Size: X-Small, Color: Purple
Purple size xs. He's 5'9" 145-150lbs. Very impressed with this suit. The color and pattern is awesome. The fit was good. I would say this suit runs large. Usually he wears a Medium in everything but ordered an XS and it fit very well. The pants were long we had to get those hemmed. There was a few stray strings by the end of the night in areas of the suit. But overall good quality. And for a great price.

We were excited and I wanted to like it but...
Size: X-Small, Color: Black, Size: X-Small, Color: Black
We ordered this for Prom and it was supposed to be a size small, which was available for Prime ordering, but had to settle for xsmall. The pants, fortunately fit well and just need to be hemmed, the vest is great and the jacket is snug. My son has broad shoulders and I was hesitant to buy the xsmall, but it does fit just right. The only thing he would need to do is unbutton the jacket while he is dancing and maybe take it off while seated and eating dinner before prom. The material is surprisingly nice and has weight to it. I was relieved it isn't flimsy. The overall look on my son is smooth and we love the pattern and the material has shine to it. I was not happy that right out of the package, the button to the jacket could potentially fall off during because it doesn't look securely sewed in. The side of the right side of the jacket has thread already coming apart. And I found a little snag in a different location. I'm really not happy about that. I posted photos so you can see what I mean. We were excited about this suit, but it's going back. The company needs to do better with quality control.
