930 intake on a 3.0???

[Slider79SC]

Hi everyone,

I was wondering what is all involved in installing a complete 930 intake on my 79 3.0 SC?

A Turbo may be in my future for the ol' SC and I thought this would be a good way to provide adequate fueling?

Let me know your thoughts.

Thanks

930 intake is good for room above the manifold, but a carrera 3.2 intake is better for flow, some people shorten and reweld a 3.2 intake on a 930 to make room for the IC. I think this would be a better way go go, then you can just plug EFI right in instead of mucking about with 930 CIS or efi injector adapters for the 930 manifold. I'd help set up megasquirt programmable EFI, it's about $300 for the computer plus a few ancilliaries like injectors and sensors, which can be had from the 3.2 you get the intake from

Man, from all I've seen locally - Kobalt hit it right on the nose - do what he says -

[Slider79SC]

Craig, what do you mean? Have you seen some bad installs?

[Craig 930 RS]

Bad installs? No I didn't mean that.

KB just mentions the most sensible way to go for what you plan to do -
You won't regret it. I've seen several 930s with this system of parts and the end product is mighty impressive in all respects -

MOTEC for the injection is the ultimate here ;-)

I agree, I was just trying to do a turbo conversion without having to rob a bank.

I can put one on the car the way it is now and have the fuel head modified but this limits me to about 7 lbs. of boost.

With the 930 injection I could run 12 lbs. and have a bit more fun.....

you could look for a BAE kit. you will most likely need an intake manifold other than the SC setup to clear an intercooler, which I think is why you posted this in the first place. I truly think a modified 3.2 manifold + megasquirt is one of the least expensive ways to do this. 3.2 intakes are plentiful, cut & reweld shorten shouldn't be too expensive (I think you have to cut in 2 places), tap a MAP into the intake, add a few sensors and some injectors, megasquirt, and you're running with programmable EFI, maybe around $800-$1000, of course you are still NA. I would do this as a first step and then add turbo headers or heat exchangers, turbo, muffler, intercooler, plumbing. you may need to pop in bigger injectors than you had with the NA setup, but just recalibrate the Megasquirt computer and you're cooking with gas.

Goran B. (beepbeep) will have something to say about this.

In terms of exhaust, I'm thinking of something like this:

FS B&B Exhaust Complete 94' 3.6 Turbo

though I don't know if the 3.6 B&Bs would work on a 3.0

[Slider79SC]

I have these 993 modified to fit 3.0, nice and short tubes. Much shorter than the factory 930 exhaust, stainless and provides heat for the street.

[KobaltBlau]

cool, you can build on those. I would still set up NA with the shortened carrera 3.2 intake and megasquirt first, that would make it a 2-step conversion where each step is easier to get dialed.

All these suggestions are great but not the least expensive.
A stock 930 CIS system and Euro exhaust would be by far the cheapest way to get you there. The only mod you have to do is oiling for the turbo. Availability shouldn't be an issue. The parts you want are the first ones to go when the hard core modd their 930s.
A stock SC engine should become a great performer when turbocharged.

While there are lot's of 930 intakes for sale, you should ask yourself why they are for sale

If possible, Carrera intake would allow you to do things "the right way" (EFI) and cheaper to boot. Squashed 930 intake doesn't flow well and isn't port-matched to SC heads. Installing 930 CIS on SC is a dead end.

Acidentally, I never saw a working SC/930 intake conversion.

Tha's what I've also seen -

[RarlyL8]

You guys always point twards EFI and future mods. Is it possible that someone may not want to do all that? All this expensive aftermarket stuff will kill the idea for someone wanting an entry level steup. YOU CAN ALWAYS UPGRADE LATER.

There is nothing wrong with the stock 930 CIS system. It will support 400HP and was used by Porsche well into the mid 90's.

Stock CIS systems are available but not plentiful in the used market. They should be but they are not. May be because lack of stock equipment hampers resale.

[beepbeep]

Problem is, CIS isn't reliable and EFI isn't expensive.

I've never retrofitted other car's CIS (and I hope I'll never have to) but I can only see problems with fitting 930 CIS on SC engine.

You would need heaps of 930-specific parts (filter housing, pipes, intercooler etc.) and it would just paint you in the corner.

Working Megasquirt doesn't need to cost more than 200$ assembled. I don't know what Carrera intake and rail cost yet, but there is nothing wrong with Tony's Megasquirt SC kit either.

If it's just fuel need that is a problem, either Carrera pieces or Tony's Megasquirt kit path is the key.

It's simpler, cheaper, programmable, more reliable, no WUR's, no AAR's, no system pressures, controll proessures that can go up-and-down, no vakuum-leak problems, osciallting idle problems, cracked phenolic injector stacks, clogged K-Jet injectors etc. etc.

[RarlyL8]

CIS isn't reliable? I've had 2 CIS cars with asolutely no issues.

Please post the address I can send my $200 for a functioning EFI setup.
You can't even buy a pair of injectors for that much money. Carrera intakes go for $500 alone.

Yes, if you are a DIY guy then EFI is by far the better deal in every way. If you are into using factory parts then CIS is the only alternative you have.

If it were my 3.0L SC engine I'd add a simple $3000 turbo kit and call it a day.
