Nice. It sounds like you're on the right path. I've had 3 different LP fuel setups and ended up with Radiums which doesn't look all dissimilar to yours but make sure you opt for a high-flow pump. My kit came with a single 255 which would be fine for your application but if you ever upgrade...
Honestly you may want to save up and go top-mount.. I had two pure800's and both pushed oil. Maybe they've fixed the issue but worth looking into.
1. If you go Pure900 you'll want 1050 injectors and those will support around 900hp. I'm at 1,100hp and needed to jump up to 1300's.
2/4. I would...
The kit was missing or came with improper clamps/ bolts and coming with no instructions meant I had to install and reinstall multiple times for proper alignment. For example: one of the studs needed either turned upside down or cut down otherwise there was a slight gap between the manifold and...
Docrace is fine if you don't need support. Found issues during install and had to self-diagnose everything since I couldn't get them to ever reply.
Go AMS, P2uned or Fullrace since the support is there.. Go cheap if you know what you're doing and support isn't needed.
Your tuner is a wise man. The only positive reviews you can find on this guy were either sponsored by Vargas or those people simply haven't been burned by them yet.
I would love to know more about this. I blew my motor up the other week and wonder what caused this for you. Did your turbo blow? I see a lot of shrapnel in the intake port.
You won't find a kit that'll push that kinda power but you might be able to find someone to sell you a kit minus the turbo? The only problem you might run into there is that a 78-80mm turbo will not fit any of the standard "kit" manifolds. Most likely you'll need to go custom.
Are you working on commission? ?
I've been following these guys and it looks like a promising kit however I'd wait and see dyno numbers if your wanting 900-1,000whp.. I have a BW 74mm compressor and it will realistically only make 1,000whp. Keep in mind the most efficient 65mm's on the market...
P2uned and Full-Race manifolds are nice but offer less control than OEM wastegate i.e. boost-by-gear and low boost pressure will be gone.. plus those manifolds require dual wastegates and BOV so there's a much higher upfront cost.
I suggest a different tuner. I've heard they are a pain but...
I doubt they will sell separate from a kit. Beside, their manifolds are typically very specific to the rest of their kit so you probably don't want just a manifold. I suggest going with Full-Race.
