Slight More power

[gdawgs]

So when the outside temp is -40°?, my engine is putting out 10 more hp than when it's 110° huh?

Too bad the wheel bearings, tires, engine/tranny oil, engine/tranny bearings,...... are so stinkin' stiff when it gets cold. You end up with a net loss me thinks.

output

Correct, not to mention the fuel consumption increases too, due to the cold weather, also if you want to pick nits, the air is much denser as well increasing drag too.

Very much so! Especially when you let your car warm up for 30 minutes in the morning, and leave it running whenever you hit the grocery store or mall.

Umm..if you thought I was saying "you are an idiot if you keep your B3" think again.

Someone on here said "the b3 gets better fuel econ" which is just BS.

The b3 in my car was getting no more than 38mpg. After B6 swap, it was getting 32-44, and now with the 1.6 dohc in there it is apparently pushing high 30's consistently (37-39)

The extra displacement out of an engine that uses essentially the same amount of fuel (not much more)....add to that the weight of the engine is the same thus the weight of the car is the same = more efficient use of its power. It doesn't have to strain & piss away gas to get up to speed like a stock B3

EITHER WAY..."slight power gains" in the B3 are pretty much impossible to obtain unless you want to spend $300+.

Best bang-for-buck mod = camshaft. YOu can get a real 10whp gain if you get the right cam BUT your fuel econ will go to shit, driveability might suffer.

The only free mods I can think of...advance ur timing 5-10 degrees (with premium fuel unless you are a fool), and reduce the weight by ripping out the rear seat & other useless crap. THere isn't any sound deadening and Festivas are already painfully loud on the highway, might as well remove that useless sound deadening behind the dash & the rear seat & carpet if you don't really need / care about it.

If ur nuts u can remove the air filter, muffler and run the car like that..i know ppl who do that shit b/c they just don't give a damn.

You guys scared the poor fella :lol: (notice he stopped posting on this topic)

Still it's an Aus Festiva... so no efi (discard power enhancing resistor)

Probably his best bet is to do a major service on the car followed by a tune up.

Things like changing the oil to a synthetic (most cars here have 20w50 or 10w40) Cleaning the spark plugs and re-gapping, flushing out the radiator, cleaning carby and throttle body, new filters (air oil and fuel)checking belt tensions, tyre pressure etc etc

This will not gain HP, what it will do is restore all the lost hp that has withered away over the years. My 121 was very zippy until the week the head finally blew (when i bought it the bubbles in the radiator told me this was due to happen soon, just sooner than i hoped)

This too would be good for prepping the engine to be tuned for 95-98 octane and getting does little ponies.

Look, I have worked at a shop that runs a DYNO. CAI's actually work especially if you get the filter out of the engine compartment. You can go on believing what you want. 8) There are LOTS of dyno sheets that show it. Maybe they don't throw huge numbers, but when your working with 2's and 3's any horsepower is still horsepower. Especially when the stock engine puts out 64 hp. I am not arguing with you, but simply stating that the B3 can be modded. There are alot of people out there that don't have any sort of wish to mod thier car with any sort of major work. I just can't believe that you would blow someone off by saying if you don't swap your motor your wasting time when a simple 'you could try these things' would have worked. Maybe put up a forum with a sticky on the demeaning mods that could make some extra power for the B3. So when the people who want to mod the B3 ask you can say - Here it is instead of just blowing them off. There are mods that do make power. Just because you don't see them as being a viable option doesn't mean someone else wouldn't. :idea: Most of the parts you would mod the B3 with could be moved right over to the B6 when you swap the block. :idea: If they made power on the B3 they will make power with the B6.

Well, I for 1 have seen a 100hp B3 that didn't cost a fortune.. so yes they can be built. Why, I don't know, but they can. But as for a few extra ponies.. my B3 felt allot stronger with the CAI, 2" exhaust and new cat. But pretty much do the maintenance then do small mods.. and I've had the CAI argument before if I had a buck for every time I typed "the filter must be OUT of the engine bay to be called a CAI" I'd at least have lunch money..

[Santos]

Maybe in a few months you will then have seen two

(unless you consider a B3 displacing 1597cc cheating?)

but do tell us how the above 100hp was configured

ram air

I was waiting, for the ram-air to be brought up, in case you guys didn't know, ram air is a 1960's marketing ploy, in order for ram-air effect to occur you need about 600mph forward speed.....I don't see any street cars doing that anytime soon.

Can't find any $300 engines then you aren't looking hard enough, and not all junkyards offer the stuff up on a platter, sometimes you need to get dirty especially at junkyards that have engines for $300. I've personally seen lots of junkyards for engines for less then that, you need to pull them out though.

Live in an apt, don't have the skills, tools, time? maybe you should make some friends that have a garage, or make the festiva your other car, or maybe find a different hobby really. my point here is if you like working on a car enough you will find a way to get what you need to do done.
Could be as simple as getting in good with a decent mechanic.

DJ where is the B3 that makes 100hp and didn't cost a fortune? I'd kind of like to see it. most people that monkey with the B3 do so because they race it in a class that makes them keep that displacement. probably a good example would be Tim Derones race car.
I'm not disputing CAI's don't make hp, but like I posted before, you are not going to make 10hp on an stock B3 using one anytime this lifetime.
If I'm wrong show me the dyno sheet saying otherwise.

I think we could all agree that short of an engine swap or serious head work with a cam, etc., the best that can be had cheaply from a B3 is to tune it up well and make sure the rest of the car is in top shape...

Tune up; new ignition parts, etc. Proper timing.

Oil change (possibly synthetics, along with syn tranny fluid) and make sure clutch is adjusted properly, etc.

Inflate tires to at least 30 psi and check bearings, etc.

Remove rear seat and any other unwanted weight; perhaps move battery to right rear.

(Oh yeah, Wil's article on the wiring trick seems like it would be a good mod, at least for engine smoothness and a better electrical system. Too bad his site's down right now--I was gonna link to it.)

All this stuff will increase mileage and maximise what hp the 1.3 has. Most of it is no- or low-cost.

When I had my '76 Chevette I read about ignition advances and cooler (hotter?) plugs. I did it. I don't believe I felt any difference (the 1400 cc engine was rated at 52 hp at 5200 rpm). While I may not have measurably increased hp, I did have some satisfaction of fooling around with my engine. You know what? I really think that counts for something to a beginner. It may lead to better things later. In my case, waaaayyyyy later!--more than twenty years!

Eh, some of my post is redundant. I didn't see the second page!

Guys, consider that if nothing else, working with what you got (a B3) at least gets you involved with your car, and if you make a mistake, well, you probably won't do it again later!

It's all pretty much good in the long run. Just don't expect miracles. If one can add a CAI, the ground wiring trick (yeah, I forget what that's called), maybe 2 or 3 degrees advance instead of 5, tune up, etc., then the resultant 2 or 3 hp increase is still better than nothing.

Now if you see folks posting about "85 hp B3s" because they added a CAI and a resistor off Ebay, then go ahead and bust their butts!

[wtfman2]

For every one here telling us swap guys we are dumb for pushing it so hard should look closer at the asked question. What is the cheapest way to add at least 10 hp. You can do all of your silly little air box mods and a ram air and a ground wire and still not see the gains he is asking for. I was only trying to tell him that there was a tried and true, not so difficult way to guarantee a decent gain for a given price. That price may be higher for people that want everything done for them and don't want to put in the time scrounging for parts. I just looked at www.car-part.com and found over 300 engines in this country for under $300 and over 50 for under $200. so if you tell me you cat find one, maybe you should start by opening your eyes.

stuff

Here, here! finally someone puts it right. People are always wanting to work on their cars, but want everything handed too them on a silver platter, oh and I forgot for free as well. The nature of hot rodding cars is getting bang for the buck, and getting dirty, is all part of it. Hot rodding a car like a festiva with a limited aftermarket and workable mods requires getting some fabrication skills and doing much more Research!!!
The internet has only made it easier for this research, of course if you want local info you could always use the ultra reliable, non crashing, analog device called a Phone book.
Just a thought.

As for the 100hp b3, the only reason it didn't cost a fortune was because it was owned by a race engine builder who has all the machining goodies at his disposal.. It would cost US a fortune to buy or make, but that particular engine didn't..
