Re: My 3.4 DOHC powered red and black camo '88 Fiero Track Car

That's awesome! I didn't realize you were adding ABS, it's neat that the BMW unit can work in standalone. Anymore details on that?

Re: LZ9 and LZ4 Fiero Swap Parts

I found this noteworthy while working on a "gen 2" alternator bracket, the bolt pattern on the end of the head is the same on an LZ as it it on the earlier engines, while this isn't massively significant, it is potentially useful depending on how a mount is developed. https://i.imgur.com/l...

Re: Lz9 + 4 spd manual trans in 86 GT swap

have you had a chance to test fit the engine to the cradle with that mount?

Re: CAD Stuff

I've been working on a bunch of projects, this model, is a LZ9 belt tensioner, with the ribbed pulley swapped for a smooth pulley. https://i.imgur.com/17i3CWp.png I also picked up a 3d Scanner, it's not exactly reverse engineering grade, but hopefully I can use it to model parts of the LZx engine in...

I swapped my 85 from auto to manual, but as others have said, it's all about what you want from the car.

Re: LZ9 and LZ4 Fiero Swap Parts

Some shots below. Couple thoughts: 1. Nice welds. 2. Real clean cuts. 3. Paint looks pretty nice not even considering how fast you made it. 4. We were thinking it might be helpful to incorporate one more bolt hole from below. 5. A gusset would be reassuring. 6. A thicker gauge would be nice Would b...

Re: LZ9 and LZ4 Fiero Swap Parts

on the subject of alternator mounting, it's worth mentioning that 3.9's installed in buick Lucernes have a different alternator and water manifold, GM parts Giant list this manifold as available, however, if you order they cancel and say it's not available. this mount fits LS truck alternators, whic...

Re: LZ9 and LZ4 Fiero Swap Parts

Most people just modify one of the stock 2.8 brackets, however, I did test fit parts on a LX9 oil pan, and they do fit the same as they do on the LZ4 pan I have, with the exception of the taller vertical part, the LZx version is too short for the older engines. Would a dual use version be as simple...

Re: LZ9 and LZ4 Fiero Swap Parts

I'm fairly certain the LS4 uses a different style alternator than most other LS engines, but I could be wrong. Either way, I have one here, and used it to validate the model shown in one of the above pictures. I cut prototypes yesterday morning when I got off work, the parts fitup looked good initia...

LZ9 and LZ4 Fiero Swap Parts

I'm slowly working towards a few LZx swap parts that should make putting one in a Fiero a bit easier. As most of you know, I have made a prototype engine mount bracket that bolts to the stock Fiero engine mount. https://i.imgur.com/gA5eF84.png https://i.imgur.com/0alG15t.jpg I'm also working on a lo...

Re: The Hunt!/Eric's new dump.

I think my plan is going to be to support the roof with temporary structures, take down the walls, bust the perimeter of the slab, dig and pack a reasonable footer, then lay block on top to support the walls, and the roof. unless I can come up with a reasonable way to to get some concrete under the...

Re: The Hunt!/Eric's new dump.

From an erosion standpoint, shouldn't grass help keep that from happening? Do you really need the square footage of the patio area? What about just demolishing it completely and making the house how it was with its old exterior walls? It may help, but I still don't like that the slab doesn't extend...
