As many of you guys saw in my
other thread, I am now making VH45 to VG30 adapter plates.
The plate is a 1/4 in piece of A36 structural steel. Instead of having counter-bored bolts, machining bellhousings or using thick spacers, this allows all stock parts to be used. Since this plate is a full circle, all of the factory brackets on the lower end of the bellhousing and the flywheel covers can be used as well..
The plate has 90° countersinks on both sides. The plate is mounted to the engine using the top 4 bolts that are counter-sunk using M10 bolts. On the other side, studs are welded into the plate (actually M10 countersunk screws that are welded in place), so that once the plate is in place on the engine, the transmission simply slides over the studs and lines up perfectly. Provisions for the starter are made, however one has to cut a small piece off the block where the Q45 starter mounted. This is well covered in previous posts.
On my car, I have a N/A trans with my plate, and the small 1/4 in spacer that is behind the VH flexplate, which works with the OEM Z32 flywheel bolts. Everything works exactly as it should..
I am offering these plates right now for
$275, which includes all the necessary hardware..
The kit includes the following:
Adapter plate
M14 to M10 threaded insert with install tool (4 pcs)
M10x1.5-90mm (9 pcs)
M10x1.5-40mm (4pcs)
M10x1.5 flange lock nuts (9 pcs)
For this price, the only things you need to supply to make this work are:
1. The stock VH45 flexplate spacer
2. Weld the 9 studs (M10-90mm bolts) into the plate
Everyone that has showed interest in my adapter has said that welding the bolts into the plate is not a problem, so I offer the non-welded version to reduce lead times and also to reduce cost.. If you would like the bolts pre-welded, I can do that... I figure most everyone that is attempting to mount a VH45 to a 5 speed transmission most likely has welding equipment at the ready...
Here are some pictures of the adapter..
