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?

Thanks Brad...

In that other post you linked too (April 2003?), you mentioned:

QUOTE
1. Average used tranny price is: 750$-1000$ without LSD (most Turbo owners yank them out and install a 915) so shops have then sitting around.

2. We can flip them for 800$ plus whatever parts the tranny needs for a rebuild.



~$1600-~$1800 + rebuild + LSD (if desired)... That really doesn't sound like a bad price compared to a 915. Cheaper core price, but extra for machining, BUT stronger trans... Whats the catch, what am I missing?

And your from Novato? Pretty much local (would save me from shipping charges?), so I am definitely interested in using your services if this project ever gets off the ground).

I am thinking the conversion parts should be similar to the 915 parts. (Flywheel/clutch/adapter/etc), and I'd need a shifter for either case...

You also mentioned a shifter for mid-engined 930s coming out soon. Any news? prices? Any other choices for cable? Thought of trying to convert a stock Porsche set-up, but figured cable would be easier... Renegade offers cable shifters for $650 and up. Just wanted to know if there is any competition out there (haven't found any on the web)...

Do you know the gear ratios and final ratio for the 930? I kind of wanted an Overdrive, but mainly to keep the RPMs down when just cruising the highway.

About how much does a Hydraulic clutch release set-ups cost for the 930?

Is there anything else I might be missing?
