I think this might have been a better avenue for sharing this build then just putting it in the cylinder head/shortblock section.

I will be posting the updates/photos from the original build thread in this format.

Thanks for looking!

I won't be posting up a picture of every nut bolt and screw but I will try to make this a semi-informative thread that follows my 2.4L build for my '97 Talon.

A good friend runs a machine shop and builds some crazy bikes (nitro raptors, etc.) and donated all the machine work and misc. custom stuff that pops up. Big thanks to him.

This is a pretty standard recipe 2.4 build:

  • 4G64 7-bolt Block - Split Thrust
  • .020" over Wiseco 1400HD Pistons - Tirado Ceramic Coated
  • Eagle Rods
  • Eagle 100mm Crank
  • ARP Main Studs
  • MAP H11 Max Duty Head Studs
  • 2g 4G63 Head - Porting by Loomis Racing
  • Custom GSC Cams (274 seat duration - 11.7mm lift)
  • Evo III Intake Manifold and Throttle Body
  • FP Race Exhaust Manifold
  • Borg Warner S256ETT - 74mm Turbine
  • 2g Auto Built by Me - Thanks to Mark @ Metro for all the Help
  • Restalled Stock Converter ~4500RPM

I am building a complete replacement for my stock motor (including all covers, brackets, etc.) so that I have a complete running spare that can be swapped in a day or two should I have any problems.

This will be a commuter car so throttle response and passing-torque are important but not focused on too much to sacrifice the overall power band.

I will be running pump/meth most of the time and either E85 or Q16 for race days.

Everything is here and mostly assembled so I just need to find time for the finally assembly and install and will be updating this thread with progress. The goal is to have the motor swapped in the coming weeks and make it out to PIR in the early spring.

:cool:

Cylinder Head:
  • Engnbldr SS Stock Sized Valves/Bronze Guides
  • GSC Beehive Springs, Titanium Retainers, and Chromoly Seats
  • Chambers modified to unshroud valves for 87mm bore
  • Full radius valve seat
  • Chamber Volume: 43cc

We looked at using AMPCO 45 material for the seats but seat life would not be good enough with SS valves and daily use. The Wiseco HDs have a 14cc dish and the block is at 0 deck. I am using a Cometic 0.066" gasket so the final static compression ratio will be 9.62:1.

Here are some pictures of the finished head. I did not get to take any pictures with the valves out as it was 1000 miles away.
