I started a build thread on the Big Block page, but since it has transitioned to a turbo build I figured it was more appropriate to have the build on the Turbo, Supercharger and Nitrous page for more visibility.
Here is the original thread: viewtopic.php?f=2&t=77784
Basically, I'm doing a budget-ish turbo build on a 1995 EFI long block that I am going to put in my 1994 F150 4x4 that is going to be used as an all around useful pickup and offroad toy.
Reading a few other builds and with input mostly from pmuller9 I have landed on this basic combo:
re-ring and bearing short block
HV oil pump
Fel Pro 1024 head gasket
ARP head studs
ported and polished EFI head
custom hydraulic flat tappet cam
probably custom intake manifold made from an EFI lower with a plenum attached to it
EFI exhaust manifolds with a Y collector for the turbo feed
Megasquirt piggyback (with the thought of switching to a 5.8/E4OD ECM so I can get a 4500 rpm shift point)
As yet undetermined turbo - I have an Ebay HX40 needing a rebuild that is a leftover from playing with my 6.5 diesel. I am going to research if there is a wheel and housing combo for this that will work well in this application. Otherwise I will go with a different Ebay turbo since I've had good luck with the one in my diesel.
I have done a decent port & polish job on the head already, but since I'm definitely going turbo now I'm going to open up the chamber so I can get my static compression ratio down around 8:1. I will be posting pics as I make progress on that. Here are some pics of my progress so far:
Intake port: I'm going to try to cut the valve guide down even further - mostly make it narrower
Exhaust port: I plugged the thermactor port with a pipe plug and then after grinding the boss down I applied epoxy over the hole. I am going to try applying a second coat of epoxy in an attempt to make the roof even smoother and more consisten
Combustion chamber: I left the fast burn features alone with the exception of polishing, but now that I'm going turbo I will be laying these walls back 45* to decrease chamber volume and increase cylinder fill
I welcome all insight as the build progresses because this is not only my first 300 build, but also my first gasser turbo build. Thanks in advance!
