Default What makes a 911 a 930

besides the engine, gearbox and bodywork? I know brakes for sure. Are the alloy banana arms a requirement for the widebody? If I pick up a 911 tub, add aftermarket front and rear carbon quarters, wing, what else do i need for the chassis besides brakes? Forget the engine and gearbox. Unless I can find a used 930 engine I'd start with the cases since this would be EFI twin turbo for the street. I'm not interested in what's "proper" just what will do the job for 500 rwhp or so for the street and an occasional DE. Thanks.

Default Buy an existing car ! !

The purchase cost of 911, carbon panels, paint, engine, gearbox, suspension, brake system, Motons or JRZ, engine management and "proper" labor alone (if done correctly by a reputable and reliable shop) will easliy be north of 50k.

At this point you'll have a car that you'll NEVER recoup your investment if you went to sell later.

You might think that you're saving money by "doing it yourself" but you won't be !

For the same money and far less time, buy a used '03 - '04 GT3 off the RL classifieds or ebay and go have a LOT of fun in a proper car (one with doors anyway !)

Hope this helps.

Good luck

Thanks for the advice, they're nice cars, but that isn't what I want. I want a hot rod, not a production car. There will be very little labor cost, probably for head work. I do all my own work including paint. I have a lathe, mill, press, MIG,TIG, stick, do all engine assembly work, electrical, etc. That's my bag, not writing a check. If I worried about recouping what I had in some of my projects over the years I'd sit on the couch all day and do nothing. I enjoy doing it, am retired and have the funds to build what I want. But what I would consider is buying a semi-completed project that someone gave up on and has some of the basic components I need.

Suspension pick up points are a little different in the back, and anti-dive spacers in the front a-arm mounts, but I know of one 935 that was re-tub'd after a crash with an 84 carrera tub. so essentially yes, you can get away with putting big hp in a 911 chassis. check out funfgruppen.com a lot of the hot rod guys hang out there.

The suspension/running gear is going to be different, 911 versus 930. Even things like the axles and CV joints are not the same. The 930 has a wider track, after all. Obviously you've picked up on the different brakes (for which you'd probably go for an upgrade over stock 930, anyway).

I think the main question you have to answer is if you're going to start with a 911 and then build a monster, or start with a 930 and go from there. For example, are you going to use stock 911 suspension and add spacers to get the right track to fit your wide bodywork? Or are you going to use 930 motor/tranny/running gear as a starting point?

That is all good info, I was not aware of the different suspension p/u points, I'd rather not use spacers. I sure don't proclaim to be an expert on these cars like a lot of you guys are. I gave up on that other site, couldn't get in as a member for some reason, not a lot of real technical how to info anyway. Pelican also has some good tech info on blow motors. Made reservations for the Rolex Daytona, watch Porsche kick a^& again! Although with the Cayenne V8 in DP.

Item number: 220718076703 ( 4 days left) '79 Turbo project with a salvage title !

Comments; In the past 18 months, this car has been on ebay (with the same price) three times with no sale. You'd think that the owner would have figured out that he is priced too high for the market ! I bet

Item number: 250737583695 (expired Dec. 11) '76 Turbo Carrera project

Comments; early, early car with cool color combo, BUT at a starting bid of 30k, the owner is smoking crack. Worth sending an email offer though !



Good luck with your project.

I know of a 78 930 in San Francisco that is an EFI project that never got completed. The engine, G-50 trans, and other good things were done right, but the chassis was partially disassembled and never completed. PM me if you want to be connected.

Buy my car, Its already 90% there! No way you could find a better car with all the parts for cheaper...If you start from scratch you are going to spend big $$$ no matter what.

The rear control arms are different as well, with a double bearing set up, instead of the single bearing 911 control arms. And they are not cheap or easy to find! And as stated previousely the axles & CV's are unique too.
Tranny cross member for the 4spd 930 tranny is unique as well + the shift linkage + shifter assembly.

The factory used spacers on the 930 to fill out the wheel wells... only the rear pick up points are different...but hell if you go coil overs on a 911 with raised 935 style spring plates you've achieved pretty much the same thing. axles and CVs are just bigger and heavy duty...you can put them in a 911 if you wish.
yes rear control arms are different, but its not a major deal. there plenty of 911 based cars out there with high hp doing just fine.

If you want a 500+ rwhp car, you can start with a 930 or 911...you'll pay more for the roller 930 chassis but in the end it all works out to be the same.

If you want a hot rod, and want to do it your way - do what I did and just say f*ck it and build the car you want just plan it all out first.

The motor is the big plan that has to be adheared to, whereas other aspects, can get expensive if you experiment - just know what you want and you'll do just fine.

If you want to join on FG Forums email me at reaper935@funfgruppen.com and i'll make sure you get through the spam filters.

Looks like you're ready to dig in for a long project, but trust me when I say - this is the right time to get into the 930 hot rod game - a few game changers are coming out soon and will allow us guys who do what we do, to do it to new quality and less expensive standards.

Just be forewarned, its easy to get to a $100k build on these cars from the get go...know what you want.

Guns951 - ok, thanks, I will email you, for some reason I couldn't get in there even after I clicked on the link it sent me. Before I kick off this project I have a couple minor items that need to get cleaned up, like divorce and buying a house. The buying a house part is done and I still have my shop and the divorce part will be done end of Feb. Your car is simply badass. Would like to learn more about it once I get in the forum.
