Alright, finally got this thing in the garage and started ordering parts
![](https://realhomemadeturbo.com/forum/proxy.php?request=http%3A%2F%2Fi67.tinypic.com%2F29lbptt.jpg&hash=112970b1c7560fd4f0cbdc1811ef617b31169fd0)
Parts on the way:
- action clutch twin disc
- used eagle ls rods / cp pistons 81.5mm 11:0 c/r
- 81.5mm hastings rings
- devcon for filling the block
- supertech valve springs
- -12 an fittings for valve cover
- arp head studs / rod bolts
- blue gates timing belt
- gsr water pump & oil pump
Going to be made:
- top mount divided t4 manifold
- either dual 38mm or 44mm wastegates
- straight 3†exhaust
- intercooler piping
Hoping you guys have some suggestions:
Is it ok to vent valve cover to exhaust? I know this is common in the big block world but it’s typically very close to where the exhaust exits the car. I really don’t want to deal with a catch can so would prefer to vent the valve cover and block to the exhaust (around where the cat would be) with -12 lines.
Ignition system: Cheapest way to support 7-800 hp without going coil over plug? I’ve looked into msd blaster coils and the like but don’t have any experience going down that route.
Which fuel pump(s) should I use? Was thinking about running a -8 feed line and then using the stock feed as a return. Planning on running e85 and going with bosch 2200cc injectors. A friend was kind enough to donate these to my build but I can buy something else if there isn’t an ideal combo here:
2 walbro 255’s

I was thinking both 255s and the 044 based on this chart:

What am I missing / what's the weak link for 7-800hp? I’m assuming the stock valves and stock cam/intake manifold need to go. Turbo is a Borg warner s300sx3 - 66/73mm, twin scroll, t4 & .91 a/r. From what I’ve seen in other build threads it should get me in that range.
