4 years ago I started a build for 800 on fuel,
kept the stock bottom end and just did some minor porting on the exhaust side of the head to match the exhaust manifold with 110 valve springs and billet pushrods. Currently ive done 767 at TSD, did highest hp @24* we tried from 24-27. TSD says I need more air. Here is a list of mods I have done:
Manning Motorsports billet 475/87.91
steed speed T-4
AFE intercooler and intake Manifold
II lightning 3's (~6x.016) worked over by Weston
Maxed Balanced 215 pump by Seth, 600cc @40psi
Hamilton 181/210
5gsk, 035dv, stock holders, .093 lines and tubes
A1000 custom fuel system
Here is where I sit, being so close, yet so far away from my goal im needing help. Im thinking my stock head is keeping me from my goal. I have been told several different options from different shops that are conflicting so im here for advice. Here is what ive been told regarding the head:
1.Switch to a commonrail head due to better flow.
2. Spray it but that defeats the fuel only goal
3. Porting and polishing a 24v head is pointless unless your cutting off the shelf and installing a side draft intake
4. Ditch the 75 and go to a twin setup, I have a billet 66/74 in the shop so I could go 66 over 83 if it was necessary but its expensive.
5. Porting and polishing will make it spool slower and will make less power
Any advice will be greatly appreciated. Im not unhappy with my # but I know of several on here through my searching who have gone over 800 with less turbo and less fuel.
Thanks again guys and sorry for the long post
