why is it every time someone ask about the 3.4 swap, I feel like I'm pulling my hair out?


Whoever with the 88 engine asking about the flywheel flex plate. You are fine, but grab the 3.4 if it wont cost extra.

whoever asking about fuel rail. You CAN NOT!! use the 3.4 fuel rail. connections arnt even close to hooking up the same. You MUST re-use your 2.8/3.1 fuel rail, WITH the 3.4 injectors.


Damn.. Karl, did I ask this many questions when I did my 3.4 swap(s)? Let me go pull what gray hair I have left out...........

KED85

Did you ask this many question....
WELL I'D SAY PROBABLY SO!
BUT
AS with any swap
IF YOU DO NOT HAVE ALL THE ITEMS IN YOUR HANDS
It's way cheaper to ask a question than "not get that part"
All ya seek is
Tell the guy
1993-95 F BODY RWD 3.4 w/ flexlplate
A fully dressed 3.4 long block.
Start working backwards from what is then offered.
Or ask him what he is including.
Hey while I'm gone someones gotta take over the answers!
Serious read my tech thread.....
Thn get the engines out side by side
All will then be answered and sure you'll have more questions, too!
I'll bet we're now up to atleast 115-125 2.8->3.4 Long Block Swap Boogie partners! by now.
You'll enjoy the project
It is a full on commitment, no stopping mid stream. That's wasted money then....
That's why I say do buy a used running 3.4....
open wide swallow the power slam hood shut.

should have specified rwd blocks, i have absolutly no concrete knowledge on any transverse mounted engines.

glad to see your going 3.4 instead kretos, i hate to see 3mm of cylinder bore thrown away!

82-T/A [Work]

I went with a 3.1 Rebuild in my Fiero for a couple of reasons...

I wanted to keep the original block (with the vin and numbers matching). The Fiero I have, is actually quite rare, they made less than 1,200 of them. Although it's not worth jack s**t, just in case, I figured I'd rather have the original motor.

Going with a 3.4 is a much better option though, you lose compression when you convert a 2.8 to a 3.1. It's not like going with a 3.1 block to begin with. You compression drops from 8.9:1 to 8.5:1. You can raise it back up slightly to 8.6:1 by going with .040 overbore pistons.

KED85

The 1987 or 88 Indy Feiro? Right?
When Pontiac goes outta production real soon, your car will go very up in value.

kretos

up here finding a fully dressed 3.4 for under 1200 cdn is impossible, but i managed to find a longblock (nothing other then block crank pistons heads etc) for 250 cdn, and since i have another complete 2.8 sitting in my garage, i'll just swap everything over and be done with it

i was toying with the 3.1 for a bit, but since i can just get the crank reground and not have to dump cash for a stroker crank, the 3.4 will end up being cheaper and give me more of what i want.... TORQUE

thanks guys, and sorry for whoring this thread

Naft

dont talk like that karl, id much rather stay in denial for as long as possible.

an 88 fiero is high on my list of cars to buy too, id rather get one before any chance of brand scarcity.

82-T/A [Work]

Well, the Indy Fiero only came out in 84. But they made over 2,400 of them.

In 1988, they had a special suspension that was designed by Lotus. Unfortunately, it's hard to find replacement pieces if any of them are damaged because they're all 1 year only components.

Not that the 84-87 Fieros handled poorly.. (they still managed a .88g on the skidpad and a slolam speed faster than the Vette of those years), but the 88s did handle better...

82-T/A [Work]

You're kind of out of luck...

If you want an 88, you'd better start looking now.


It's really hard to get a running V6 88 Fiero for less than 5 grand right now.

I often see them go for 10,000+ on eBay for ones with less than 80k miles on them.

KED85

I enjoyed driving a 1985 Fiero for 3,000 miles all within the whole state of California in 10 days.
Well handling car is an understatement. Ask the CHP cop in San Francisco I met! What a memory!
PS Plenty of room when ya drive that Feiro through the giant Redwood trees, too!
Whatever 3.4 parts ya can get is a plus. And yes scoring the short block is best place to start.
Indy Feiro was 1984?
Yeah the 1988 Fiero is a highly sought after ride....
After Pontiac goes outtta production, you'll really see prices jump.
Start looking now.
I got one out in SoCal if ya want it.
Wife's Cousins fully loaded Fiero.....may be pricey, tho....I think it's Black.

Naft

problem is i wont be ready to buy one for a good 5-6 years!!!

no matter though, when the time comes it'll happen, and if an 88 fiero gets too expensive by then, ill just buy a late c4 instead, lol.

82-T/A [Work]

So it's 88 or nothing?

There's nothing about the 88 that the 84-87s can't be upgraded to outperform.

The Fiero store (www.fierostore.com) and several other places sell a kit called the "bump steer kit" which gives the same corrections that the 88 suspension had.

They all share the same wheels, and there's more aftermarket suspension parts available to the 84-87s.

Naft

nah i wasnt sayin that, i was just saying how its all in the future, which definitly hasnt been determined yet, so ill just bide my time and see what happens.

82-T/A [Work]

Well, I've got one, totally rust free with all it's panels, only thing it's missing are the front and rear bumpers.

It'll be missing it's engine and 5-Speed getrag.

But it's yours for free if you want it.

5-Speed is going in the other 87 I have, and the motor will be a spare.

kretos

he's offering a free fiero, man we have some nice people on this board

kretos

done

Naft

You serious? It would probably sit covered & protected for a few years before i would have the $$ to do anything to it(my current car is taking all of that, grr), and it would be a trick getting it from texas to cali, but i may have to seriously analyze this possibility . . . replacing drivetrain/etc is no problem, i would end up doing that anyway . . . wow.

82-T/A [Work]

I'm dead serious.

I'll be done with the car in about 2 months... and then you can have it for free.

There's no rust on it, and the interior is actually immaculate (no tears or rips on the seats). It has the deluxe interior, and all the improvements that the 88s got except the suspension. All 87s got the revised wiring with the new headlight motors and all that other stuff.


The only thing is, I don't live in Texas, I live in Fort Lauderdale, Florida...

But if you want it.. I'll hold it. I'd like to get rid of it within 6 months, and I'll need it for another 2 months (from today's date).

You know, unless you could ONLY pick it up like in the next month, then I would just work double time to get the transmission out and the engine out.

I'll even give you the free custom fitted car cover for it.

KED85

FYI
It costs about a grand to transport a car cross country.
No matter how you look at that cost, it still adds up to $1,000, minimum.

Speaking of free....
I got a free Flat Firebird hood, 1985 for anyone.....nice nice shape.
You pick up. I'm in SoCal.

I love Fiero Seats! Wish I had another set! Hint-hint!

Naft

thought lauderdale was in texas, woops. i think a few months from now there is a chance i could have some way to get it over here, i'll probably send you a pm or email if i find a way . . . all i need is someone i know travelling from florida to california that i can slip a few benjamins to if they pulled a car behind them, lol. its a pipe dream right now, but if you had that car still lying around in a few months i may be able to mcgyver a way to get it over here. damn that would be sweet.

82-T/A [Work]

Hey, just let me know... I wouldn't be surprised if it's still here in 6 months anyway. I just built a patio next to it... so it's kind of ghetto to have a car under a car cover in my backyard... but I should still have it for 6 months I think.

I got a q on the 3.4 swap.. Can i skip the FI and keep my carb?

kretos

yep

Firebreed

sweet, less stuff i got to mess with,

KED85

Look at my posted pictures

82-T/A [Work]

Well, not exactly, you're going to have to re-Jet your carburetor... or your car will be running really lean at high RPMs (very bad for the motor).

The 3.4 would do well with something in the range of 400-450 cfm. The 2.8 works well with a 390 Holley, but you'll want to go to something slightly larger, and make sure you jet it.

IMHO, you would do well to buy yourself an Oxygen Sensor aftermarket kit. It comes with an O2 sensor, a bung, and the gauge so you can see when exactly you're running lean... so you know if you need to not only rejet the primaries, but the secondaries too.

KED85

In answer to those ideas,
Thank you
Since I haven't gotten my 3.4 set up to the road, yet, all I can report is that my idea was to make a spacer for carb base to increase airflow.
My hold up was longer correct studs for the intake & carb nuts.
I'm restricted to stock and am seeking a spare 2SE carb for my Blazer.
My carb is for a 49 state federal version, non-electric carb/distributor. Original as my Blazer came into CA due to purchase from outta state.

Firebreed

I realized that i would have to go with a different carb, all it means is less work for me rewireing my car

Dale

Whats to re-wire? You use the wire harness that came with the car.

Alot of people on the s10 board suggest going with a more carb style cam. However, the camaro cam does work with a carb.

Firebreed

Cali wants you to have the hole wireing harnees from the donor car if you are switching to a obd II motor/ however sincie im gonna get a obd I motor i dont got to do anyrewireing, and since its gonna be Carbed instead of FI even less wireing i would have to worrie about

Dale

iTrader: (12)

Didnt see that you were carbed, and cali.


But for any who are already mpfi, their is no re-wiring needed.

KED85

Make your end set up look my carb'd picture set up & you are doing great.
Mine is a "stock" as can get..... Only difference for you is the wiring to the sensor to the carb for electric solinoid.
