Firebug's V6 Gemini

[firebug]

No turning back now...

Progress:

With help from Holden202T the motor is in the engine bay, just not fully attached. Engine mounts are giving us grief but will be sorted soon. Custom sump was re-modified to suit L67, some meat taken off the engine block and bell housing.





Wiring loom stripped of ancillary shit we don't need. From this:



To this:



Surge tank and fuel pumps in...

Turns out we had all sorts of trouble fitting the new engine in. The 4L60e if quite a bit fatter than the T700 so out it all came and took to the tunnel with a grinder...

After much discussion we decided instead of fabricating in a VR Commodore tunnel Holden202T had spare, we should try and modify the original tunnel and see what happens. The gearbox mounts were the main concern if we cut out the old, so we bolted up the cross member back in place for support and to maintain its position while the modifications to the original occurred.

Original tunnel



Cutting







As a result, we sliced down the middle of the tunnel and in a few places across the front to make it wider and taller. There is also more room now for the intake manifold and coolant pipe...



Welding back up



Then I ran out of gas so I'm off now into town to get a bigger cylinder.

So inside all but done other than the replacement section for the B&M shifter to mount onto, the old setup was a hacked up setup that was not very sealed and certainly not the most rigid. We are fairly confident that will no longer be an issue with the new section we've started to weld in but I hadn't taken a photo of.

Werd...









There is an abundance of room around the gearbox now. Now to make a new gearbox mount.

So .... Here we are up to the present ...

Its a shame it never saw the dyno to test the before and after hp!

Although I'm sure you'll know seat of pants!

Ps. Love your signature.... Hehe

Good project and nicely done so far. The buick v6 often enough ends up in geminis but this has become a fair bit more interesting. Keen to see how it progresses from here. You've certainly got the right person helping make things fit.

This is really good!

[psyolent]

agreed, awesome. i remember a friend had one of these years ago - blue coupe with a VR v6 and 5 speed in it. he loved it to bits. this will hammer badly with the super v6 in it. awesome stuff

[Holden202T]

this will hammer badly with the super v6 in it

that's what we are hoping
