6 bolt 4g63 in 2g Eclipse GSX cylinder head removed in under 10 mins
Removing the head of a 4G63 in 10x speed.
The project got delayed a few months. After finishing it and cranking it
over, Interference in the cylinder was discovered. Shamefully, I admit my
mistakes were: 1) Not putting the spark plugs in immediately after
installing the head. 2) The bad habit of using my Valve Cover as a parts
tray and 3) Putting off the project too long, so I didn't recognize a
missing bolt from a custom fabrication.
The head needed new valve seats, valves and some welding. Wiseco and the
machinist both thought I'd be OK running the piston after smoothing out hot
spots, but I ordered a new piston not wanting to risk the deep gouge in it
with the high Boost I plan to run.
Peace of mind is priceless.
The danger in being over confident is sometimes you skip triple checking
stuff. I've built that engine at least 5 times and got careless.
You can see the port work I did on the head @

1999 Mitsubishi Eclipse GSX - GSseX Season 2
This is the second year I have owned the GSX and this is its second season
modded. From last year alot of things have changed, and to my friends and
the few subscribers, here are the updates on the car.
I know last year I was planning on Drag Stripping it but the idea of going
down a line didn't sound fun, and the idea of road racing Leguna Seca was
alot more appealing. The Evo brake swap was probably the most difficult of
the installs mostly because of the gathering of parts, and a seperate video
was made for that.
As for next year, I have the G4CS block, 1G head, and other 6 bolt parts
required for a 2.4 liter DSM. The FP 3052 turbo is a Dual Ball Bearing turbocharger that will hit full Boost right around 3500 RPM on a 2.4l, the
perfect size turbo for spooling quick
around a road course. the FP 3150 is still a possibility for even faster spool, but after months of debate, I
still won't be able to pick until I finally make the call to order one of
Thanks for watching!
