Well, since this seems to be the thing to do nowadays I'm going to show you my 4.9 conversion.

My Fresh 4.9, I rebuilt it and replaced all the gaskets and waterpump.

I bought a 86SE sight unseen so I could use its engine cradle and transmission before I tore into my 87GT. I drove 5 hours to pick up the car which turned out to be an 86 coupe with SE written on the side. It was an honest mistake, I can understand the confusion.

Today I removed the engine cradle from the coupe, it wasn't hard but definitly time consuming. I'm not sure but I may be the first person to use farm machinery to do so

87GT 4.9 in progress!

looking good u will probly have yours running before me i am still wating on my fly wheel and clutch and heads to be done

keep up the pics and good work

------------------

I hope to have it done by June. I live 2 hours away from where I'm doing the conversion so I can't work on it in my spare time, just days off. I'm going to Vegas the last week of April so that will put things on hold.

The only thing that I think will suck is converting my auto 87 into a 5 speed isuzu. Anyone have experience with this? Seems like it won't be fun running the hydraulic lines.

This is off topic but in one of those picture is that an out-house in the back? Just curious.

On topic: Are you planning to do your own wiring and passkey defeat, or are you using a harness from the fiero factory? I'd love to do this swap eventually - what made you decide on the Isuzu 5 spd?

Off topic: Are those 15" Sunfire wheels? Are they for sale?

Way off topic: I bought some parts for my old MR2 from a gentleman with a tractor - dont ever lift by the strut tower brace!!!!!

Great pics. I love the usage of Farm Equipment - I think that's how most NASCAR guys started out in the 50's. Almost nostalgic. Good luck on the swap. 4.9L's were great in Caddys, it's even going to be nicer in your ride.

You might want to research here on the forum in past topics. From what I have read the 5 speed isuzu will not hold up to the torque and power of a V8. A 5 speed Getrag would be better for a manual or just use your auto tranny from your 87. Just passing along some knowledge.

An Izuzu can't handle V8 power? That's only true if you're taking it to the extreme. The Caddy 4.9 has a good amount of torque, but not exactly gobs of HP - and the Izuzu has been used in numerous SBC (Archie) installs without problem... don't worry about it unless you're planning on gobs more power than the 4.9 was designed for.

Looking for Fiero posters?

We use an isuzu trans behind our 3.4TDC w/ ZEX and drag radials. Been runnning Goodyear canted lever racing slicks on road courses and autoX without tranny failure for 7 years. But to be fair it does have a quaffie LSD in it too.

Me personally, I would keep the car an auto trans and use a 4T60e.

Yep, what Steven said,

I'm running the 4.9 with the 4t60e, because
i thought that it would be easier (wiring wise) to use the auto and also cheaper.
The only "beef" that i have with the 4t60e is that it shifts too softly.

Ed

I meant to say that the auto wiring would be easier than the stick if you are running the PFI. If you are going to run a carb (no ECM)
then the stick would be easier yet.

WOW! AWESOME!

Well here is what we did today. We seperated the engine from the transmission and found out what was knocking...

And a closeup, you can see the metal debris inside the crank case.

------------------

87GT 4.9 in progress!

Crzyone, I'm going to have to really keep an eye on this one, I'm really contemplating if it would be worth it to rebuild the tired 2.5, I'm really thinkin that it would only be just a bit more to install a 4.9. You have to take me for a ride when it's all said and done!

Right on, good choice!

Edit: I forgot to add that my car also has a five spd Izuzu as well... it looks pretty similar to the 86' you bought there...

GO LEAFS GO!

You betcha. I'll be going to meetings this year so I'll see you there.

And yes, that is an outhouse lol!

Thats some awesome work there. It's going to be the best move of your life...great engine...now if only someone could take away the iron heads and floating sleeves these engines would be unstoppable!

Great Work!

I'm not sure, but I thought only 84 4 cyl engines had the "tech 4" decal on the top of the engine? If thats the case it would explain the rod through the block. When I took this engine out alot of bolts were missing, thought this might not be the original motor.

------------------

87GT 4.9 in progress!

THis must be a commen place for a 2.5 to throw a rod i have had 2 of them throw the rod in the same place.

check out how thin the walls are on the 2.5 block is very thin.

P.S. Good luck on you caddy build

------------------

Well I have some updaes on my progress
I have the engine mounted to the transmission. It really is a very nice fit, almost like a V-8 was meant to rest on there.

you can see the clearance of the crank pully, there is quite a bit of room. I still need to level the engine and take measurements for engine mounts.

You can see here where I need to notch the bellhousing for the cadillac starter. Again, lots of room on the side of the engine.

Crzy, you have a P.M.

Thanx,
Sean

Did you find all the seals and gaskets in a kit somewhere, or have to buy separately? Do you happen to have a source and/or parts list for the seals?

thanks

Thought I saw Red Green peeping out from around the outhouse! Good use of the farm machinery!

I actually got a gasket kit from Canadian tire. Its a felpro kit but it is missing some key gaskets. The kit cost me $300 Canadian but the extra oil pan gasket and timing cover cost an additional $100 from GM.

Sorry it took me so long to respond, I has no idea anyone was still replying to this thread.

i somehow doubt that carb will flow to the engine's needs, will it runs with t? Sure it will, but it will probably nock the power down to that of a 4.5 or less, should have gotten a 500 CMFer

Dude. Bubbajoe and Stevenrossi are running the same carb, they have no issues with lack of power. Joe claims equal or better acceleration than PFI. This is what he claims, don't start flaming me.

At 5000rpm this engine needs 390CFM. I don't see how its not going to flow enough air.

This carb is off of a chevy 350, has almost a liter more displacement. I'm sure it'll do just fine.

I'm looking for bottom end grunt, I have a wet nitrous kit to help out the top end.

For those of you that want a 500cfm rochester they came off of large trucks with 454s. Nice big 2 barrel.

Back in 1976 I new a guy who put a 650cfm Holley on his 4.3L Chevy Monza, I put a 450cfm spreadbore Holley on mine. His was hopelessly overcarburetted, bogged off the line all the time, mine was fine, and quicker, since the small carb left me with lots of low end torque. The old way was to put on a big carb and lots of cam for the big power numbers, fine for an SBC or a BBC but for this little Caddy, you only have about 4500 usable rpm (5000 is pushing it) and there are few performance parts so go for the fat torque curve by using a smaller carb. As already pointed out, at redline the engine only needs 390cfm so the carb is good throughout the usefull rev range.

BTW crzyone I am hoping to follow your example next year.
