SCCA rules, rule out big bore motors Options

Grant, How is your Z a 2500lb car???

Its missing some stuff.

At least in XP.

A fantasy of mine is to keep my car all Porsche and put in a 993 3.6. While the car would be +/-100 pounds heaver it would have over 300hp (with Varioram) and around 250lbs of torque. It would be a great hill climb car able to compete with the big bore modified cars.

OK, but then what do you do the rest of the year? XP rules would dictate ballasting up to 1997#. Are you kidding me?

So the only way to be competitive in XP is to convert to a Suby or shove in a twin turbo motor, just like everyone else.

Annoying.

Honestly even with 3.6 you would be down on power to fastest cars. Kippermans tube frame car will be completely rebuilt by next season with big V8 Poor little 300 hp 914 wouldn't have a chance against that car. Even my Z will be making 425 hp soon. You have to go either V8 or blown to be top dog in hillclimb. Or go with water cooled 6 from GT3. No doubts your car would be very fast but suspect it wouldn't be as fast as high hp cars at some Hillclimbs. You'd be a fast SPO car for sure. I'm going to SPO next year would be fun to run against you in same class. With Avon race slicks, 2500 lb car and 100 more hp the Z should be pretty quick as long as I keep it on the road! Lol!

I'd not worry about SCCA classing. You do mostly local ax and you'd be plenty fast in E mod with e mod PAX. PCA you'd have TTOD car.

If there any doubts about hp being king of Hillclimbs just look at Rob Bs GT2 setting 2:11 in SSP at Hoopa. The car is a rocketship. Made z06 corvettes look slow!

Rob's car is a rocketship on a hill and it ought to be as it cost a bundle. Rob's car is fast and he's a good driver, but not fast enough that he didn't get taken out at a "local" event this year by a old 914. (IMG:style_emoticons/default/smile.gif)

One way of winning is to have a bigger budget than the next guy, but it makes for expensive bragging rights. (IMG:style_emoticons/default/hissyfit.gif)

Autocross doesn't put premium on power like hillclimbing does hence poorly prepared FP/XP cars including mine can beat his SSP car. However if your talking about a king of the hill winning hillclimb car me thinks you will need more than a NA 3.6.

However the big block chevy guys don't have nearly as much money as us Porsche and Nissan guys do into our cars. And they will run away from a 3.6 NA car on a hill. Dave was several seconds faster than Robs car at Hoopa in his tub frame beast last year. Yet we could likely beat them or be within a second in most ax events.

I also think you'd spend more than you might think converting to 3.6. If done properly. You will run into lots of issues you haven't experienced with lower powered lighter t4 powerplant. All of a sudden you won't have enough brake, you will get chassis and suspension flex too. Drive train will need to be replaced, etc. t's a long expensive road when you put power into a 914 race car. Why fiddle with nicely balance 4 cylinder car? It's fast local AXer and top of heap in SPU at Hillclimbs . I'd focus on making it fast SPU car - much cheaper route.

Also consider that beyond motor mods hillclimbing and ax rules don't mix well for prepared cars. You can run wing or much aero in SPU or SPO.

If your goal is to have TTOD at both ax and Hillclimbs a blown formula Mazda will get you there easier. I understand the fun in tinkering with a a given platform however. My Z is getting faster and faster but id have to go full tube frame and put motor in middle with twin turbos before I'd have a record setting hillclimb car. Ill settle with something that is fast and has a chance to win its class. But even at 450 NA HP my car will be extreme underdog in SPO with 600 hp plus cars

Correct typo. You cant run wings in SPO/SPU

SPO is a tough class in hill climbs. Sonny's Cobra runs Cascade 7+ seconds faster than I do, but he's making that time differential up on the straights, not the corners. There are a number of formula cars that would make top contender hill climb cars. A Radical running up a hill would be crazy fast and if that doesn't make you happy then move on up to 3.0 liter formula cars.

Actually Brits car would be excellent at hill climbs. Not sure Britain wants to run hill climbs, but (just saying) let Cooper drive it up a hill and see how far it would be off the pace.

Britt would have to rebuild/regear

Just swap out for another gearbox. I know people who swap pumpkins on BMW's depending on the course.

True but I believe he has a flipped RP in a 930 box. So the spare box with gears will run 5 grand

Wow, do you have a pic? I mean that car started out like 3200 lbs right?

Thats substantial...
