Well, I put one motor in mine. The original motor had blow a head gasket (surprise!) prior to me purchasing it. By the time I got it, water hasd ruined 4 cylinders. I priced over sized pistons and they were about $125 a piece. I just bought another motor instead. While I had it out, I saw how much room there was and decided to plan ahead for the next engine.
Here are 2 photos of the right motor mount prototype made from scrap steel:
It is relatively simple mount. The left side, I have designed but not made yet. It will be more complicated due to having the starter in the way.
I truly admire people like you who can build a car from scratch.
Those 3800s are almost bullet proof. Alternator once in a while. Vibration dampener at about 60k miles. Superchargers seem to fail at about 36k miles on many cars (and brand). One GM mechanic told me that if the owner of a supercharger fails to check/add oil in it after 24k miles, it will go out. ???
Trannies are strong too. I hear that the torque convertor lock up switch fails on some of them, but I think that is easy to get to.
Thanks, I appreciate the luck. I hope to make it appear and function as close to being factory installed as possible. I have done engine swap before. See the photo of my 1985 Trans Am with a big block Chevrolet engine.Everything is functional and factory style:
Here is what I am after.This is the factory Holden with a 3800 SC:
The biggest problem so far has been interpreting wiring between the cars But I will figure out somehow.
I purchased another Catera that has rear body damage over the weekend so I could use it for parts and a test mule for fitting the engine. That way when I get it all done, all I have to do is swap it and there will be less surprises. I got a factory Holden airbox amd SC throttlebody comming. I also have started working on the radiator set up. It appears from measurements that a 182-1992 camaro radiator core with 1995-1999 Oldsmobile side tanks may be the closest fit with factory apearance and function.
I figure no more that $1500 - $1750 to do the complete the swap. I still have to get the mass air flow sensor. The Holden version uses a seperate throttlebody and MAF sensor. I also need to get a transmission from a Camaro / Firebird for the trans upgrade.
I see well please keep track of everything as i may be interested in the swap and i know a fabrication guy so if you tell us exactly what is needed when your done you can be the pioneer of the 300 hp catera project =)
I been getting the parts on eBay. The only problem is some people won't ship outside of Australia. If you choose to buy something, have it shipped Sea mail, it take about 8 weeks but it is much more reasonable to ship. One cool thing I found is if you use a HSV spec prom (Holden Special Vehicles) it will raise the standard hp from 240 to 255 before any other mods. 300 hp is becoming a reality.
