What would be the order of 930 engine mods you would do?

This will be a Street/AutoX/TT car. Has full cage and will weigh about ~ 2100lbs (hopefully).

Some recent PICs of Progress

This guy wants to progressively get to About 400HP while using the car.
Anything more than the easy mods suggested is a waste of money for the application.

A street 930 CIS 400HP car is easier to drive than any normally aspirated hotrod. Period. If you can't tolerate turbo lag then you have no business driving one.
ANY mod you do to a stock 930 engine will make it more "street freindly".

An no, you weren't driving 930s when I was in diapers. The 911 hadn't even been invented yet.

[scca_ita]

Thank you all for the input. I have a lot of work to do still and look forward to learning more once the motor goes in.......

Happy Holiday!

@ rarlyL8
I didnt wanted to be rude , this is my second language ( i am from Germany ) and sometimes i am missing the right words .
I had a lot of 930s in the 80s , some from the best Tuners around , Ruf , Kremer , etc. I have to admit they were fun Cars and very fast , back then .
But have you driven a later 965 3.6 or yet a 993 TT , they are truly different worlds and drive like NA cars with a moderate Fuel consumption and Power that makes you breathless .
If i had the choice to mod a 3.3 or sell it and spend 6-8 K more i would go 3.6 or spend 10 more and go 993 TT .

As far as I remember, Speedster94 is actually Harald. When I was a newbie on PP, Harald was already very respected member of the board with imense knowledge of 911 engines.

His german-tainted english sounds poetic from time to time, but I learned never to question quality of information coming from him.

Good to have you back Harald!

Well if the premise is easy gradual mods to get to 400 rwHP then I stand by my original suggestion. I get 400+ when I'm into full boost but find the car pleasant to drive slow when I don't feel the need.

'course with 400+ on tap I feel the need pretty often. But I still wouldn't do an engine swap if I was looking for easy and gradual.

[Speedster94]

you are talking about 400 HP at the wheels from a 3.3 Turbo at 1 bar ?
that would be 450 at the Engine , you must be kidding .

[BlkBird]

Yep. 422 rwHP SAE. 396 rwHP uncorrected in Atlanta numbers. Something like 466 ft-lbs SAE torque.

It's a wicked toy with the top down.

[hobieboy]

Well, drivability is relative. Based upon what scca_ita shows (pictures) I suspect he's not looking for something quicker than a 350z Turbo from light to light AND something that can keep up with GT-2 on the track at the same time. I could be wrong...

Goran, I think there's quite a more work to fit a 3.6 into our chassis ? What about tranmission? axle? These are all in addition to other "standard" fab that might need whether its 3.3 or 3.6?

Of course, its hard to argue about better suspension on the 964 cars; though that is one of the 930 charms on track, no?

[ZLP]

Some of you guys are getting way too old.... The lag is half of the FUN of driving the 930!

[RarlyL8]

If money is no object you can do anything.
The original post asked for gradual upgrades to achieve 400HP from a 3.3L 930 engine. He did not ask for a $50,000 ImagineAuto EFI special.
I guess we need to quote a budget as well.

And yes I've experienced modern turbos. They're booring, like an extremely fast Lexus.

Well that is a good question. I would say for the sake of discussion less than $10K not including initial engine purchase.

I will also turn my own wrenches too.

OK so I have a '87-930 with 26k miles --basic stock...and now I have the same bug everyone else has been talking about... Please give me the sanity check.. I was thinking about the following... and in this order..

-Better suspension set up( this I need to do more research on)

-B&B headers,exhaust and heat exchangers ( need the heat in MD)

-K27 model 7006 ( maybe Kokeln... any concerns)

-Kokeln intercooler

-Tial 46mm wastegate

- 1 bar spring

- HKS boost controller model EVC

The real issue is how to get this as a package.. Imagine Auto has their stage 2 package ( $5K -No Tial) which I used to model what I thought would be appropriate. Looks to be a decent package but they dont spec B&Bs for their headers...However I like some other products I have seen and if I buy them from the other sources my costs get significantly higher..

Does IA offer to substitue various items.. anybody ever done this with them?

What CIS mod is really required for this application...How would you map something that is in so basic and mechanical and pre-set or am I missing something...

[fastbacker]

I have an 88 930 (4speed) and was asking the guys over at Smart Racing/Jerry Woods Enterprises about getting 400hp out of it.

One of their suggstions, which made alot of sense to me, was not to touch the engine and regear it - that is, unless I wanted flames from the exhaust and hot and cold start issues.

What is the diference between the 930, 965 Motors? I know the the 993TT motor is a twin turbo 3.6......I have seen people refer to the 965 as a 3.3 and 3.6?

[SCHNELE]

The 91 and 92 964 turbo aka 965 has the same engine as the 930, the upgrades on the 965 included coilover suspension, K27-7200 and I believe larger intercooler the 3.6 was only available in 1994.

If your budget is <$10k, I think BldBrd and RarlyL8's list is about as good as it gets. I'm rebuilding my engine from ground up at the moment. I don't even need turbo, CAMs, WG, accurate gauge and exhaust and I'm still looking at close to $10k for parts alone.

And don't forget to leave some budget for suspension

CIS can support up to 400HP, you don't have to do anything to it.
If you wish to go beyond that point ImagineAuto will mod your fuel head.

Because these systems can be 30 years old it is a wise idea (in my opinion) to monitor the A/F ratio with the proper gauge and/or have a dyno run performed that maps the ratio for you. I would venture to say that most WURs that old are not working optimally. An adjustment screw on the WUR is also a good cheap mod.

[930LDR]

sorry to revive an old thread but... RarlyL8 can you provide any other insight on the adjustment screw for the WUR?
