Slant six turbo cost analysis: 300 hp

I just purchased a few of these things on my build. I'm just verifying most of what was just said with my own experience. The Walbro 392 can be had for $90, and it comes with fittings and a mounting kit. Ebay was the only place I could find it that low. MY intercooler and piping kit was $130. It came with enough piping to build two slant intakes, and a 28" x 4" x 8" intercooler. You just have to take some remover to the words "JDM sport" on all the couplers. A small price to pay.

The regulator you mentioned I see mentioned a lot and suggested heavily around the net. No matter where I have looked, there is NO regulator that will work to be had for less than $100. The first one I bought wound up being for EFI and you could not get a baseline below 40psi. The new one I got is by QFT. It's a quick Fuel technology 30-1899. I got it off Amazon for $120. It allows you to put Holley style jets in it (facing the pump) to better adjust whatever you need to do and has a boost reference port on top. It is adjustable from 2-9 psi baseline, and increases 1:1. I bought it because it was the quickest shipping thing I could get to quit spraying gasoline all over the place. See my build thread if you are not familiar with what happened. lol The exhaust costing $300 is probably accurate.

I can find the U bends all day on Jeggs for less than $20. The turbo flange itslef is around $15 anywhere, and then an exhaust flange is 2-3$. The wastegate flanges if you use them are around $5.00/piece and almsot no one makes them because everything is V-band now. V-band is much more convenient for sure, but those flanges cost money too. You could do the whole U/J pipe for about $50 if you assemble it yourself. If you don't have a welder, expect to pay someone else to, so that has to be taken into account. BUT that's if it's made of steel/ mild steel. If it's made of stainless, the flange costs double, and the pipe may as well - I'm not sure.

Also, $200 must be included for all the bolts and fittings you forgot to buy with the other stuff - guaranteed. The turbos I've seen seem to neglect having any hardware included for mounting. ALso -AN fittings are not cheap at about $8-$10 for ONE fitting if you need to buy it at the store. Then there's the brass fittings for tapping your oil sender, the drain fittings, etc...
