HP gains Options

[matteyp]

Does anyone know if they make jug kits for the 1.7? If so what hp and performance gains can be expected? Are there any other cheap performance mods for the 1.7? Thanks for the help guys.

[jetboy]

ha ha, you said cheap. giggle.

[matteyp]

Wow that helps lol

[RJMII]

define "cheap"?

I wanted more HP; so I put some obnoxious setup in my car that requires lots of tubing and ways to keep the air and fluids cool...

as to your question about jugs; yes. There are 96mm pistons and jugs out there for the 1.7 that increase volume to 1911cc displacement. There are two different versions of jugs though, the kind that require the heads to be fly cut, and the kind that don't.

you may find it less expensive to find a decent running 2.0 and install that.

If your upgrade wants are guided by a desire for "cheap", then make your engine a good running one by adjusting the valves and doing a tune-up and making sure the fuel injection system is optimum. Quests for "more power" are funded by cubic dollars.

The cheapest way to boost your ride is to take weight out of the car... get a sawzall off CL and go nuts...

Seriously, these are old motors with old technology so not much is gained vs what you pay or do to get there.

This might sound "crazy" but regardless of power, these sleds get more exciting to me when they have a nice balance of suspension upgrades... like 140 lb springs, a larger swaybar, and tighter torsion bars...

any noticable gains over stock reality:
$100 per 1H.P.

like has been said though, get it tuned, running great and enjoy.

I have a set of 96 MM P/C for a 1.7 head. they tend to be a little thin where they fit into the head. I,ve never heard of a problem though. In addition to going to 1911 CC they are flat top pistons instead of the dome tops . CR should be a little lower. Then again the larger bore will raise CR probably=. If you want them , let me know AL

Matteyp,
First, ask yourself why you want more HP. These cars aren't drag racers. It is about carrying speed thru the corner and accelerating to the next. If that is what you are looking for, get the suspension working best you can, get brakes working great, put some good tires on, then get some seat time driving the car. If you want a little more acceleration without modifing the engine, you could go down in tire size to like 50's or so and get a little extra grunt at the expense of gas mileage and engine wear. That 1.7 will give a lot of thrills. My first 914 has a 1.7 and it was a blast in the twisties. I had f/g flares and 235's on the rear with 215's on the front and was running 60"s so I had a little extra grunt and the tires made the car stick in the corners very good. My buddy's 1970 "6" would eat me up on the straights, but my wider and lower aspect tires would make up the ground in the corners.

All good suggestions and questions you should be asking yourself...
Research, then do a little more. I have a 1911 with one of Dema's cam's and heads from Bugpatch. Fun little motor that is very responsive. That said, if the rest of the package isn't up to par, ie suspension,brakes, alignment,et, your car will still be leaving alot of the fun factor behind.
And most important, do you like to wrench? (IMG:style_emoticons/default/beerchug.gif)

HI Matteyp,

I'm just finishing up a complete engine rebuild of my 1.7 L and have installed the 1914cc, 96mm Big Bore kit from AA Performance. This alone should be good for
10-15 HP and a good slug of torque. I would look at tweaking the F.I a bit richer. if that is all you do.

For my engine I gone all the way: Big Bores, mild cam, Duel-throat Webers, $200 main bearings from AutoAtlanta, flycutting the heads to 1800 cc specs to fit the new bores, replace all guides and valve job. Shucks, for a little old VW engine, it has cost me $1000!

I guess the real message is that HP isn't cheap. A machine shop I went to as a kid had a sign on the back wall: "Speed costs $$, How fast do you want to go?"
Sorry, there's no cheap short-cuts.

Best,
Terry

So now you know why Chris "giggled" when you said cheap. The $100 per hp figure seems to be spot on.

Find a 2056 and have fun, otherwise; drive the piss out of your 1.7 (if there's any left in there) and do the suspension mods that some of these guys have mentioned:

Nice shocks
New Bushings
Sway-Bar for sure
Killer tires and
Awesome brake pads

There is a rebuilt 1911 in the classifieds cheap ($500). It's in the bay area but you aren't likely to beat that. Even driving down to pick it up it's worth it for your car.

(IMG:style_emoticons/default/agree.gif) http://www.pmbperformance.com is where to get that stuff. It'll change your experience through corners and canyons enough to where you'll forget about 0-60 times. well, almost forget.

MatteyP -

I'm the guy selling the 1911 in the classifieds.

I really liked the 1911 in my 914. Not tremendous power, but well-balanced for this car design/weight. Never did I feel reluctant to smash my right foot down coming out of a corner... just the right amount of power, I thought.

From my experience, make sure whatever you build will be reliable. DRIVING these cars is what it's all about..... nothing fun about seeing the car parked while in the process of a "weekend fix" that lasts several months.

Cheers and happy driving!

[RJMII]

A 1911 for $500? really? That's a good deal. (IMG:style_emoticons/default/smile.gif) What pistons did you put in it? Were the heads flycut? This goes along with what MatteyP asked about, the bigger jugs... all the work done for a little more than the cost of the pistons and jugs and machine work.

Mattey,

You've got a ton of local guys to look at for examples. I can't remember if your 914 is FI or carb'd?

I like 1.7's.

Bring your 914 to a local teener event and then ride around in a stock 2.0FI, a carb'd 2.0, maybe a 1911, 1.8 and so on.

Just slipping in a 1911 P/C kit won't really yield much for the money spent.

I have seen some pretty crazy 1911's with proper cams, head work, tuned carbs. But in the end, they should have started with a GA or GC 2.0.

You're best bang for the buck is probably to find a good stock 2.0FI and just do the conversion. It'll add value to your 914 as well.

The 2,0 longer stroke is makes them bettter imho.
The 1.7 engine in your car will need more than PC's.




shameless plug;
I have a 1973 2.0 complete. I dont know if it ran or not no keys and the body went to minnesota and the motor has been in storage since.
maybe good - maybe bad ,But it is a better start than the motor in your car.
The big plus is your car stays driving untill your ready to swap it out.

The price wont be bad as I gave Rich the 1.7 with injection.
