Transaxle choices, Choices and questions for V8 swaps Options

[NoPorsche]

Hi,

I am new here, and looking for information on transaxles for a mid-engined Chevy V8 swap.

I guess i should first say that the vehicle will not be a Porsche, but the Porsche transaxles seem to be the best choice (cost vs. strength). Therefore, trans length and CV joint strength shouldn't be issues.

Some places (Renegade) rate the transaxles based on engine HP, not torque. Others (PowerHaus) stated that the 901 and 915 were bad choices, and go with a 930 as a minimum.

Budget is an important factor, but I realize any choices are going to be expensive (clutch/flywheel/adapters/starter/cable shifter/etc are probably going to cost over $2K alone).

I have pretty much ruled out a 901, and budget-wise, I am leaning toward the 915 or 930 boxes.

This will not be a race car, but maybe used for so uncompetative racing (like to try AX), but I'd still like to have enough power for quick accelaration (sub-13 second 1/4 mile) in a 2500+ pound car. I am thinking of a mild 350 engine, maybe minimizing low-end torque if needed for trans longevity.

realistically, what can a decent 915 and 930 handle? I have heard that the 930 is stronger and gear ratios better suited to V8s, but more expensive. Are the 930s in ALL 911 Turbos?

How difficult is the process of flipping ring gears? Is it straight-forward, clearance the case and reinsert carrier backwards and set-up the gears?

I am thinking about buying a core locally for chassis mock-ups, and wouldn't mind trying the flip the gear myself (lots of assembly experience but not too much fabrication experience yet).

Any places I can buy a cable shifter setup (Only found one through Renegade)?

If I wanted to use a hydraulically operated clutch release (as opposed to the cable), which trans would be a better choice?

Any ideas on the prices of the whole package (including cores)?

Anyone else thats good at this work (I have heard of Brad, and plan to get in touch when the project is more real, just on the drawing board right now).

Anything else anybody could add?

930 box all the way. Dont even stop to think about the 915. The biggest headache with the 930 box in a mid engine config... shift linkage.. I'm not too fond of cable and we really dont have anything out there for the box that works "great". For ease of install.. run the cable setup.

See this link for the last 930 box I did.

Unless you have access to CNC's/Bridgeport/ and R+P setup tools.. you wont be doing it yourself. Check out my pics in the above hyper link. The 930 case doesnt have room for the ring gear on the other side of the case. You have to cut a hole in the case and make a patch inside the bellhousing for it. Not easy. You also have turn down the thickness of the ring gear and the bolts that hold it on.

If you looking for cheap... 915 is the way to go... but the ratios are not correct. The 930 box is like driving a 67 Muncie 4 speed Camaro.
