Re: in a car?

you would have to marinize the engine, spark arrestor, marine starter, alternator, etc.

He wants to put a boat engine in a car, TD, not the other way around.

Re: in a car?

I understand the hot setup for the fiero is finding a "quad 4" HO engine from a grand am and it will fit. It gives the most effective power to weight swap available.

The 3 liter might pose a whole new set of problems.

Re: in a car?

I remember reading that a small block v8 will fit in the Fiero engine bay. If you really want a rocket, look for a v8 conversion kits for the Fiero. The added weight of the V8 would not be a problem because they are really mid engine cars, the weight is not hanging out the rear.

Check out the Fiero V8 conversion site:

Re: in a car?

1st, the 2.5 GM Tech 4 engine and the 3.0 Marine engine are NOT the same. Not even close. Just look at your Fiero motor to see the MAJOR difference. Your car 2.5 has intake and exhaust ports on opposite sides of the head, as God intended. The marine 3.0 has all the ports on one side of the head.
2nd a 3.0 in a boat is rated at 135hp.
3rd, neither the 2.5 auto engine or the 3.0 marine engine has ANYTHING in common with a 470. And you don't want anything to do with a 470 in a boat, let alone a car, if you can help it.

My advice, buy a Fiero with the 2.8 V6. Much better than the the 4cyl. And if you really want a rocket, yes a SBC will fit and that's what you should put in.

Re: in a car?

we did a 350 conversion in high school... 15 years ago.
The car was absurd to the point that it was barely drivable.

Ayuh,...

As noted by TilliamWe,... That's totally False....

The 3.0l is an old Chevy motor....

The 2.5l in your car is an old Pontiac motor that was adopted by GM for it's corporate motor...

They are Very Different motors....

See, that's the kind of fun I'm talking about! Of course my dad and I put a ZZ3 crate 350 in an 83 S-10 regular cab short bed truck. So I may be a little nuts when it comes to overpowering cars!

A Smart is instable at any speed above 60MPH, which is why the are governed from the factory. It was the only way they could get them legalized for street use here in Europe.

The last place I want to be at 200MPH is in a Smart, I don't even like being in one at 60MPH. :eek:

Now the Lotus Super Seven, & old school Mini, R1 Yamaha or a Suszuki Hayabusa motor conversions are a different story.

Mini: http://www.zcars.org.uk/videos/winmedia/black.wmv

Check out these two vids, they are of a “Seven” running a custom built Hartley Enterprises Hayabusa V8 motor. It is two Hayabusa 4 cylinder motorcycle motors combined into one V8.

I would like to someday use one of these motors in a small boat.

It sounds soooo sweet! Kind of like a F1 outboard on steroids.
http://www.h1v8.com/f/h1.mpg

SPECIFICATIONS:
75 degree odd fire V8
2.8 LITER, 170 cu. in. displacement
84mm Bore X 63mm Stroke
4 cams, 32 valves via internal silent chain
530mm wide x 485mm long x 530mm high
400HP @ 10,000 rpm with stock street cams
245 ft-lbs torque @ 7500 rpm
200 lbs engine weight
Billet nitrided steel 180 degree crank
4340 Carrillo H-beam rods
Billet 6061-T6 aluminum crankcase
Dry sump oil system with 4 stage pump
7.25" or 5.5" Twin disc clutch
DTA S80 full sequential ECU
Unique cylinder offset and cam drive arrangement yields a compact Patented design

... or maybe a Mini with a 2 Litre Honda Civic engine.



But the over weight Pontiac Fiero, is not a good candidate for a motorcycle engine, now matter how good the engine is. It needs some serious tork to move all that dead lead.

Now that looks interesting! :D

Especially with the chop top and six speed gear box.

At an increase of only 150lbs, it is really a no brainer if you have the spare cash.

Re: in a car?

Snapper, I can attest that you can fit 2 high school aged boys and two high school aged girls (none of us were over weight at all) in a Fiero with a sunroof and the driver is still able to drive the car. I know, cause I am that driver! We had two people ride in the passenger's seat on more than one occassion. Our one friend was so thin (as was I) that we actually could put the seat belt around both of us!

My car also only has seats for two. What we can do, what we have done, and what we should do, are not always the same! Safety first!

Not that any of my post in this thread up to this point, put safety first though. You should always follow the manufactures passenger recommendations :rolleyes: , and over powering is a “SIN” :eek: , punishable not only by the local LEA :rolleyes: , but also by your communities scorn. :D

P.S. Got any photos of your Fiero?

Re: in a car?

sorry snapper, my dad has all the pictures. It was his after all, I was just the typical teenager driving it around on the weekends! Sure wish it had been a 5sp, though.
