I know this has been briefly discussed before ( https://www.fiero.nl/forum/A...060206-2-064963.html ) but that was all of 5-6 years ago. what are the chances of one being swapped here in 2011?
Before I get ahead of myself has anyone even attempted to do this?

Most inline 6 engines can be placed into one of two categories:

1) those which don't fit
-includes the Chevy, Toyota, Chrysler, Ford I6 engines, etc.

2) those which fit but are undesirable
-includes the Suzuki Verona 2.5 I6, etc.

I say go for it. Tell us how it fit.

a VR6 is a pseudo inline 6...

There's a reason Pontiac used the V6.

Get your tape measure. Measure the length of your Duke/V6, then measure the length of the inline 6 of your choice.

i highly doubt you would have room. ive contemplated pulling the drivetrain from my 300m and stuffin it inym fiero its longitudal v6 with forward mounted axles on the tranny. it would definitly fit i measured. so if i ever total my 300 i can tell you what is going on my cradle!!!

doesnt gm make a 5 cylinder truck motor? that might fit .i dont think there are many i6's that will fit

Yup, the 2.7L in the Colorados and Canyons. I have never owned one, but I have heard a few good things about them. It would be interesting to see a Inline 5 or Inline 6 in a Fiero. Maybe one out of an old Skyline or a BMW, maybe the BMW Z3 Inline 6 might fight. It would be an interesting swap though, but it could get expensive.

Volvo makes a I5 that might fit as well. The H3 hummer uses one too.

Edit: GM's I5 were the 214cu in (220hp, 225lb ft) and the 223cu in (242hp, 242lb ft)

they also have the 4.2 i5 thats in the trail blazer.

spit the car down the middle and make it 4" wider. you can probablt fit a strait 6ix in that way.

Best thing you could do is go Junkyard hunting and measure the space required to install it in the Fiero then measure the engines you find. But you might have to go the Longitudinal route with the engine.

If you want to shoe horn six in a row, you might as well stuff a 6.6L Duramax in there.

I like this guys idea, but powerstroke.

I have a J2Z (320hp supra engine) and a 3.4 DOHC v6, sitting next to each other, the length of the 2 are very close. I think the 2JZ will work, but can't find a frontwheel drive toyota tranny that will work. A boosted single turbo 2JZ in a fiero would be nuts! They already put them in S2000's. It would be interesting.

Lol! 2jz with nos! I saw that on the supra site. Its funny.

That's not a i5...

That's okay, because Toyota's FWD transaxles wouldn't hold. You'd probably need a custom adapter and a built 4T65E-HD

I was reading on a forum in the past a guy used a 2jz and an adaptor plate on a 98 maxima 5 spd trans. Was doing research for my friend who wanted to boost his 3.0 maxima.... Interesting stuff I tell ya. Especially if you've ever seen "hells" supra on youtube. Pushin 1k hp out of a friggen fiero that would just be pure insanity. You would need 10in wide rims with sum wrinke walls and a set of wheelie bars haha..

I personally like my 3.5 in my 300m 256hp 270ft/lb tq. All n/a. And it screams in that 3900 lb sled. I could only imagine it in my fiero espeically after weight reductions..

[sarcasm] Nope, absolutely no way an inline 6 will ever fit in a fiero... [/sarcasm]




A small bore inline six should be able to fit with A LOT of work.
To fit the V12 required shifting the transmission about 4" to the driver side, reworking the passenger strut tower, reworking both frame rails, and a custom tubular cradle with the suspension pickups moved outboard.

is that an M70 BMW v-12 motor or an M-73? now that would be an original swap a European V-12..

I can understand why someone would put a V12 in a Fiero. I can't understand why someone would put a tractor engine into a Fiero.



I've got a '60 stovebolt six in my other driveway

But you don't need a 2JZ to get 1000 hp into a Fiero. The LSx is a much easier way to get there. I think we did a thread last year discussing the best build for that goal.

My '87 Opel (not available in the US) I had in Germany had a screamer inline 6. I drove it nearly every day on the autobahn at more than 100mph and on occasion as much as 135-140mph. I measured the engine including the water pump it was about 28 inches long. I found one in a junkyard but couldn't figure a way to legally get it back to the US. That would be a good engine to try to get through Mexico. (but not as good as phonedawgz's stovebolt 6 )

That year Opel was made to directly compete with the Beemers.

Wow, interesting, a 98 maxima 5 spd with an adapter plate for a 2jz. I have to look that up.

you know that's a V8, right?

Fieroguru, what tranny are you using for that inline BMW engine? Great job getting it in there.

Russ Fiero is doing the BMW V12 swap (not me). He originally mocked up the engine/tranny with a 4.10 4 speed, but since then I traded him a 3.65 4 speed and I am pretty sure that is the tranny he will be using.

Phonedawgs,
That looks like a Chevy 216 from the 40's / 50's; I cut my teeth on those suckers. I truly lovely engine when maintained; weighs about the same as a couple of Fieros.

A W8 or a W12 would be very cool in a Fiero. I love the sound and uniqueness of those engines. A VW Phaeton is on my wish list of "Need to Buy" Cars. LOL!

My 88 jeep wrangler yj had an inline six, and my guess is if you want a straight6 with plenty of torque that would be a good one. It was put in those jeeps to climb everything as long as it had traction. it'd smoke the tires all day too being stock. I'm about certain it would fit but of course measure and find what you want and need. Length wise that is. You'd need to check the height on that one.

235 if it had an automatic......might as well go all out

GM's Atlas family of engines has three members

4.2 inline SIX - 275-290 hp
3.5/3.7 inline FIVE - 225-242 hp
2.7/2.9 inline FOUR - 175-190 hp

I don't know why you would want the inline five or four - they are not exceptional in any way. The 3500 would almost match the performance of the I-5, with more refinement and better fuel economy.

if the firewall was extended into the armrest or further and fabricating a larger armrest... an inline 6 should fit..
im thinking the trans will be the determining factor or key to the swap..
the BMW M1 might shed some light on the possibilities
