Everything back from the Machine Shop

[Bart001]

Well thanks to some advice from Colin and a couple others everything is coming back from the machine shop tomorrow...lol...
3100 V6 1995

Block work
- Hot tanked and Painted
- 0.030'' Bored and Honed
- Decked
- Freeze plugs and screws
- Cam bearings
- Crank grind 0.010''
Crank from the 2003 3400
Valve Train from the 2003 3400
new Fedral Mogul bearings main and rod +0.010
New Camshaft
Hypereutectic Pistons 0.030 over with rings
Every single new gasket, FelPro, Updated intake gasket
2003 Top End
with the newer roller fulcrum rockers and larger Valves
Valve Job
Heads milled 0.010
Port and Polished with gasket match
Head Bolts
2003 Exhust manifold ported, Pretty different than the 3100

I think thats everything.... better be, costing enough....lol...
now the 95 3100 come with what 155hp....
I'm not building for power, but i'm hoping to get at least 20-25hp increase....

Why didn't you just swap in a 3400?

[Xeiros]

What did that end up costing you?

[roksoc]

Sorry for my nubiness but what does decked mean?

[Bjornboy81]

some of the surface is machined off the heads or block (0.01" is shaved off) in order to reduce volume of the cylindar, thus increaseing the compression ratio.

Did you do anything with the cams? any special grind?

You should get a nice little gain from that :)

[Bart001]

iceman.... do get all smart and logical with me..lol.. that probably woulda been a good idea....lol... .I bought a 3400 but when I took it apart the cam was in 2 pieces and it milled a quarter inch outta the cam journal.... block ruined...
Sooo now I got a solid cam instead of those hollow weaker ones...

Thus far 1200 cnd maybe a couple hundred more....

Thus far 1200 cnd maybe a couple hundred more.... But a solid cam weights more which means more power required to turn it. And since when are the stock cams weak:???: Never heard that before.


that's a good price man :)

[coupe]

Still woulda been cheaper to drop in a 3400......

[Bart001]

When I was talking to the machineshop guy hes started rebuilding these 3400 engines but they all had broken cams,

come on.... Hollow compared to Soild its a no brianer...much stronger, and with the cam bearing redesign of bigger oiling space and less bearing, this is just a bad mix....

Thanks thou the price is pretty good

It just seems over kill...stronger yes, but heavier too. Whatever works for you. :)

[Bart001]

how much cheaper?? and what kinda suprises am I in for..?? lol

Basically this is a brand new engine i'm dropping in.....actually better than new....

[Xeiros]

Not to thread jack or anything, but what do you guys think would be a good price for a LD9 block to be remaned and overbored .10 with forged rods and pistons? I'm looking to not get taken at a repair shop when I go have this done sometime in the near future.

I was wondering the same thing.

That much into machine work, and all the time to remove and reassemble everything I would be shooting for atleast 200hp.

[99blackSE]

Spray it!

[Bart001]

I know everyone was saying just drop in the 3400 in....

But where would I get one??? scrap yard? wrecked car from a careless driver, and careless engine upkeep
How much would it have cost??? at least 800 bucks.. used...
What kinda suprises would I be in for later???
Would have to redo the intake gaskets in a month or so....
Since it WONT have the updated intake gaskets or felpro head gaskets....

and really when it come down to it.... isn't everyone here in this to have FUN, and pull an engine out and rip it apart, then rebuild it...lol... I got a sweet job for the summer before back to school in sept and making decent coin to do it too...
I have a set of Titanium intakes that I was gonna have machined oversized and put in too, but time is ticking and yes cash is a lil tighter after dropping 1500 cnd for everything...

And how much would a Brand new 3400 cost, from the dealership?? cause thats REALLY what i've built, but better, cause its updated with the best gaskets, Real quality was put into the engine with machining and the hours i'll put into it....lol...

I Think a brand new 3400 - 0k would cost about 2500bucks, brand new never started at least... up to 4000 bucks...lol..

[TA^Guy]

Well I paid only $900 for a 4.3 Vortec with everything on it including a distributor with only 14,000 miles on it and a warrenty.

I'm sure you could find a 3400 for that much or less.

My point is, all that work and your hoping to make the same power range as a engine you could have pretty much swapped in alot easier.

[Xeiros]

I wish I could swap in a 3400 in mine, but it would probably be a royal pain in my ass.

[Bart001]

2.4L , Four Banger right???? Those can make just as much power as the 3400..... just gotta do Engine work.... cam, porting, valves, computer, boring

[Xeiros]

Oh, I know it's not hard to make as much as the 3400, it just seems as though it is a lot easier to find more performance oriented stuff for the 3400.

If I go all engine with mine, I don't see making much more than maybe 200HP, and thats probably putting a good chunk in, and if I go the forced induction route, I have a headache from hell when trying to turbo it (supercharging it isn't even an option with me).

Also, i've asked this before (excuse the noobness of it) but what the hell is porting? I know it's benifital to performance if it's done to the intake and exhaust manifolds, but I'd actually care to know what it's actually doing.

[Bart001]

the four banger should make 250hp....

Porting.... gm makes like 1 million cylinder heads, casting... the quailty cant be the best, sooo inside theres lots of imperfections.
soo you grind out so the air flows better, faster
if you look and feel around you'll see stuff that just doesn't look good....lol....

then put in larger valves... more air flow....

this can show you some stuff....

More Air flow = More power
an engine is nothing more than an Air Pump

To get 250 n/a on my car, i'd imagine I'd be spending a helluva lot. I'm just guessing here, but I'd imagine something to the tune of racing cams, a race head ported and polished, a bigger intake mani (ported as well) and throttlebody, and a ported exhaust mani and very unrestrictive exhaust system.

[Xeiros]

See the funny thing is, I'm looking to get 250WHP out of my car when everything is all said and done, but I'm not looking to spend over 5 large doing it, and I'm realizing here, that exactly what I'd be doing to have it all engine. I'd likely be better off getting a custom exhaust mani, a T3 turbo, FMIC, and the fuel upgrades and tuning software needed, and go that route. Probably wont be much cheaper, but any little bit helps.
