hey is that a HEMI

Pillsbry10

iTrader: (1)

hey thanks for the awesome response and telling me all about your car in someone elses thread i dont recall asking.

and by hacking i ment cutting. obviously i didnt take the easy route either.

anyways, that thing looks awesome in there cant wait to see some more stuff on it. glad you dont have to make any firewall modifications. it would have been kind of funny that to get a 4 banger in there you would have to "hack" the firewall

Fallen2603

Well, TECHNICALLY, the combustion-chambers are hemispherical in shape, so, YES, it is a HEMI!

Now, some Hemi-guru will start plotting my assassination for my "blasphemy"...



Yeah, that would have just been riduculously IRONIC!

Aww come on now, I didn't mean to bash or flame in any way, but I guess my lack of concern over cutting a bit to achieve that last little bit of an advantage would be a bit overkill for the goals he has in mind for this build. Maybe an auto-x car would gain a little bit by moving the engine further back, but even as it sits it will be much better balanced than any v8 f-body.

Glad to see you got it to fit all the way in there, Fallen.

Fallen2603

That's what she said.

Sorry, I couldn't pass that one up. My cohorts and I have been going back and forth with those for the past two days while working on this...

Yes, if this were going to be an autocross contender, I'd definitely go through the hassle of moving the engine as far back as possible. But, as you also said, this should be damn close enough for what I want to do with it.

LOL! My roommate/cohort said I have enough room for a still! Booze machine, anyone?!

Or, a car that produces it's own race fuel...

That looks killer in there and have fun changing your oil filter

Fallen2603

72vega,

Actually, even with that stock, black "thermoplastic" intake manifold on there, I can get to the oil-filter compartment a lot easier than on my Cobalt SS Supercharged. Why they couldn't just put the oil-filter into the oil-pan...

Another reason I'll be using a different intake-manifold. That way, I can change the oil-filter while standing up.

iTrader: (11)

It is going to be even easier in the 3rd gen than in my Solstice. Get oil all over trying to get the filter out from in between the firewall and hoses.

Y_B_A_FOOL

Don't make me feel bad if I'm wrong... But I believe I see an issue with your set up.




Sorry, I haven't had the time to read everything about your set up and if this has been brought up... I'm sorry. But, I do remember reading on the Fiero forum someone swapped an Ecotec into their Fiero and has mounted the engine straight up and down like you have. I believe the engine should has a slight angle so the oil can drain from head. Maybe you don't need to do this if you have a dry sump?

Hope its some helpful input, I would love an Ecotec in my Camaro. I really want a twincharged car

Fallen2603

scooter,

Oooh, I didn't think of the Solstice. That sounds like about the same kind of mess. Yeah, a lot easier in a 3rd-Gen...

Y_B_A_FOOL,

No, that's not a stupid question. Actually, I think it might be the first time brought up on this thread, but I could be wrong...

While the Ecotec has been tilted about 5* towards the exhaust side in about every application that it is in, it doesn't need to be. Plenty of hot-rodder's who have done Ecotec swaps have run the engine "straight-up" without any issues at all.

Honestly, most Ecotec guru's are a little baffled why it's always tilted, too.

If you do decide to go through with this kind of swap and you have questions, don't be afraid to ask, man! I'm more than willing to share my knowledge!

lunati397

you have to do more firewall modifications than I have to do and im putting a duramax in mine

Fallen2603

That would have been even more ironic! LOL!

The Devastator

Tubular front suspension was one of the best mods I've done so far. Made my big block swap alot easier. Plus all that header clearance!

Fallen2603

The Devastator,

Yeah, all that room the tubular front suspension will create will make the engine look even tinier with all that extra open-space. LOL!

All that extra room will be in all the right places, though.

iTrader: (11)

I have been creeping in this thread for a while and to all the naysayers; if you get the car to the 3000lb mark it isnt going to be slow at all if you gear the car right and especially if you are turbocharging it. With me in the car my Solstice weighs 3000lbs and I weighed at the time an even 200, and the factory rating for the HP is 177.

So more HP and close in weight is still going to make for an awesome ride.

Fallen2603

AMEN.

However, most people STILL won't get, or believe, it. No bother...

Current plan is 3,000lbs., or less, and turbocharged to about 350WHP or more, if possible.

Sounds like fun to me.

lunati397

its not to hard to get a thirdgen under 3000

also what is the RPM limit of that motor and what is the gearing for that trans

Thirdgen89GTA

iTrader: (5)

I think the redline is in the 6,500-7000rpm range. Don't know for sure, I don't own one.

lunati397

if its that high hell 4.11s will make up for TQ and low end then the power will hit and run it out

I think 3.73s will be a perfect median for all around to stay in the boost and get that low end but it depends on what the final drive for the trans is

Fallen2603

The Ecotec's, stock usually redline between 6,500-7,000rpm. With the stiffer valvesprings, balance-shaft deletes, and the cams I'll be running, revving it to 7,000-8,000rpm shouldn't be an issue.

Taken from Post #306, page #7, of this thread:

Tremec TKO-500
1st - 3.27:1
2nd - 1.98:1
3rd - 1.34:1
4th - 1.00:1
5th - 0.68:1

I was thinking about running 4.11's, and that should be pretty close to Solstice gearing. But, I haven't made up my mind on that, yet. Still a ways away from there...

lunati397

with the .68 final I think 3.96 or 3.73s will be better they will keep you in the gear longer letting you utilized HP over TQ becuase you dont want to run out of gear at 120mph

Fallen2603

Damn...I'd run out of gear at about 120mph with 4.11's?

Maybe 3.73's would be a better choice, then. LOL!

Fallen2603

Wait, what'd you use to find that 120mph?

I just used this:

http://www.apexgarage.com/tech/gear_ratios.shtml

And, I got a top of 130mph in 4th gear, with 4.11's.

Is there something else I should be considering, that I'm not?

lunati397

I didnt do the math but there are calculators out there but with 4.11s that final you will be up there in RPMs you will have alot more than 120mph but you want to look into it when picking the rear gear sacrifice top for bottom or sacrifice bottom for top end the goal is to get somthing that works all around

with my 383 setup with a t56 (final .50) and a 3.42 rear with a roughly 27inch tire I could do 186 according to my GPS now if I switched to 4.11s it might be more around 140-150ish

Fallen2603

Yes, but compared to your 383, I have about 1,500rpm, or more, that I can use. Yes, this is at the top, but it's still used for speed.

I do know that my Cobalt with 4.05's and gears of 3.37, 1.76, 1.18, 0.89, and 0.70 manages to cruise at 2,500rpm at 60mph, and a hair under 3,000rpm at 75mph.

The TKO-500 is pretty close in gear ratio's.

Also, I'm not counting the over-drive gears because top speed is more a matter of aerodynamics, wind resistance, and weight in that case.

Fallen2603

This is what I did way back in Post #306 of this thread. I was trying to find what gear ratios to go with that would give me more Solstice-like performance, because, in the end, my car will behave more like a Solstice than a Camaro, probably.

Now, according to those calculations, I could go with 4.40's and be quite close to Solstice performance, but I decided to cut the gears down to 4.11's to give the turbo a little more resistance to help spool-up.

I'll probably use the 4.11's first. If I'm not happy with them because cruising RPM's are too high, or for any other reason, I'll adjust to a different gear-ratio.

Oh, and if anything I've assumed or calculated in the above post is wrong, and you have a good reason why it's wrong, anyone, feel free to say so. Thanks!

lunati397

first off you cant quote yourself

secondly if you carry the two and divide by 6 well you get a poptart

lunati397 says so

Fallen2603

I'm not quoting myself as a VALID source, man! I'm just showing what I did, and how I got the numbers. That's all...

I didn't get a bunch of people at the time screaming, "This is WRONG!", which is what a lot of people love to do in this thread, so I figured it was okay numbers work.

But, if it ain't, I'm all ears as to why it is not good reasoning, TRULY.

Enjoy your Pop-Tarts!

The Devastator

THIS IS WRONG! Use an LS1!

Fallen2603

I was waiting for just that! LOL!

Y_B_A_FOOL

Bumping because I'm stoked about this swap!!!! Can't wait till you get it running

Thanks, man! All in good time...

awsome man glad to se eu getting this done

Fallen2603

project89,

Thanks, man. Wish it could keep picking up speed, but I guess plodding along is better than no progress at all...

iTrader: (1)

the longer it takes the more u apreciate it when its done, im going on over a year on my twin turbo iroc and its still not done, hell ive prolly only put about 50 miles on the thing in the last year, and 5 of those were towing the thing with a chain behind my niebors truck from one end of town to home when i grenaded the 700r4 the first time out

Fallen2603

project89,

I absolutely agree with that. I haven't driven this car since April 2010, when I first picked it up and drove it home. I definitely feel your pain.

Atilla the Fun

Not too late to drop in a stock Ecotec for driving while building this one for big boost.

lunati397

sold my 383 motor back in 08 my cars been motorless since then but did travel in a trailer from FL to NM in 09 and hopefully it will breath life again sometime in 12

KrisW

iTrader: (5)

I agree!

It might be beneficial to have a stocker, wrecking yard pullout example under the hood to help you "rough in" the details. Just in case you run into weird problems (like cooling system or oil system failures due to the new application) that could take out your experimental engine.

Plus I'd like to see it drive hahahaha!

Fallen2603

You both bring up some very valid ideas. I'll do some more brainstorming on this, and see if I come up with pressing reasons not to do it.

No promises...

I have the same goal: Running and driving before the end of the world.

lunati397

so Dec 21 is the deadline

Fallen2603

Yup, at least some zombies will get a look at it.

v6 f-bodys weigh around 3100 dont they? thatd be awesome with an aluminum engine like that
