VS calais

[maldotcom2]

Well i've got started on the engine project. After going on cruises with V8's and seeing how much more fuel they use i've decided the long-term enjoyment factor versus the long term expense isnt really warranted.

I considered a supercharged V6 but i think i'll just go with a reliable high comp NA v6 with cam and head work. I've got the engine stripped down to the block and i'm at the point where i need to talk to someone about cam specs and how much compression i'm gonna need to get the most out of it, also whether i'm going to get that compression from shaving the heads or whether i'm looking at flat top pistons.

[maldotcom2]

Ok guys it's all happening now.


Block has been cleaned, tested, decked and honed to size. I've got the flat top pistons, all new bearings, double row timing chain and i should have the cam tommorrow. Cam is a custom grind billet similar to a stage 3 crow.

Pics!







Damn surface rust.




The grinding on the inside is where i've lightened the pistons to make them all the same weight.

What it sit on rpm wise cruisin in 5th at 100k's?

[maldotcom2]

Well at 110 it revs at 2500. So a bit less than that. It guzzles the fuel on the highway.

you can thank your 3.7's for that.

[ethann]

How'd you go fly wheel etc putting the t5 behind the ecotec?
I want 3.7s but not sure if I wanna justify big fuel economy lol.
Do you happen to know if theres much of a difference between 3.08 and 3.45?

[maldotcom2]

you can thank your 3.7's for that.

Yep. I believe that's why he asked the question.

As for the conversion, i used all the parts from a VR. Solid flywheel etc. 3.7's are fine unless you do a lot of highway driving which i do since i changed jobs. I changed my diff back to a standard one today. Personally i wouldnt pay to go from 3.08 to 3.45, but that's just me.

Very Very nice, and clean!

[vn_v6]

nice mate, should go like stink

[nathanVY]

that is the cleanest calais ive ever seen. well done.

[maldotcom2]

Thanks guys, here's some more pics of the engine build.

[maldotcom2]

The engine's finished. Here's some pics of the long motor.

mmmmmmmmmmm so clean, what do your reckon itl pull on the dyno? do you know if the oil in the sump goes all the way to the top of the sump at the front of the engine there? just a question for my oil return on mi charger

[maldotcom2]

No idea what it'll get on the dyno. I'd be happy with anything over a 30% increase. I doubt the oil goes to the top, but don't quote me.

[HamaTime™]

Any recent progress dude?

[nathanVY]

This is the cleanest car I've ever seen lol. Nice, hows the cam?

Nice ride m8

[maldotcom2]

Hey guys, thanks for the interest. The motor is complete and run in, runs like a dream. I'll have some photo's up soon of the install. It was very rough before the tune as is to be expected, idle was pretty lumpy and very loud. Downshifting was basically burble city with heaps of backfiring. It was also getting no fuel above 3000RPM. Obviously a tune was essential.

I had it mafless road tuned and it feels very nice for a 6, unfortunately most of the lumpyness went away. Cam is fine for around town but above 3000rpm is where it really kicks in. I haven't had a chance to run it on the dyno yet.

Fuel economy is about 11L per 100K around town. 9L per 100K on the freeway.

Nice mate. Good to see the motor is finished. Get it dyno'd and post a figure.

What else is on the cards for it, performance wise?

[kuzman89]

Nice clean VS, as above get it dynoed!

[redvs2]

Hey mate what the full rebuild end up costing you?
And what power figure did you come out with?
