Sounds fascinating, but what can you tell me about the 'high compression block'? Are the compression chambers in the block, rather than in the head?

That might be a well-known thing for he Z32 guyz but I never knew about it before now.

The Z31 VG30E (whether W series or not) comes in two versions Low Compression and High Compression, depending if you have a Turbo or not.

There is no notable difference in head design (just camshaft specs) between Turbo and Narurally Aspirated engines, it's the pistons that determine the compression ratio.

Blocks are 99% identical.

I would consider the compression chamber as located in both the block and head. Air fills the cylinder and is compressed until the top of the stroke.

The cylinder head area is probably better considered the combustion part of the overall "chamber."

Thank you, sir.
Back in the days of wood-spoked wheels ('wagon wheels') when everything 'automotive' was new, several companies experimented with putting the combustion 'chambers' in the pistons rather than in the head. They had heat issues which were resolved by flat-topped pistons and wedge or hemispherical combustion chambers in the heads.

A walk thru CHICK's huge junkyard in Wallingford lets me view several dozen old cars and trucks from the 1910s ~ I was amazed to see some of them had overhead valves. Others had sodium-filled valves, made of nickel ~ the entire rest of the truck had turned to rust, but those valves still gleamed in the sunlight.

I suspect there is absolutely nothing 'new' left in the automotive industry. Probably everything we hear of today has been tried at some point during the past century (including variable valve timing, turbocharging, dual ignition, variable-speed transmissions, and multiple valves per cylinder). The early pioneers of this stuff simply couldn't afford enough R&D to make them reliable or affordable, so the ideas failed either mechanically or financially until modern companies with huge resources could afford to make them work.

Altho I'm SOLD on the early Z cars, I find those VG30-series engines pretty promising, and I suspect it can be made to squeeze a lot more ponies out of it than the average Z driver could ever use on the street.

Definitely.

While not as "cool" as an RB or VG30DETT, the VG30ET can make LOTS of power, reliably, for cheaper and in a smaller package.

I should be able to put down a solid 300 to the wheels with my basic modifications and a good tune, on the T3, with a little breathing help from a friendly gas.

OH :shock: I hadn't even considered Nitrous. I tend to think in terms of throttle, not bottle.

*(Rick ~ a big trick today is to rig the cars with a tank of Nitrous Oxide [laughing gas] to inject into the cylinders for brief bursts of extreme power. It requires somewhat manly bearings and rings to begin with).

Alert and apolgy: Mild Hijack

What is this huge junkyard you speak of? I need a good deal of stuff from donor cars in the future and I live in Wallingford :)

:end hijack:

Cheers,

We've actually had some pretty great times at CHICK's. He's a bit costly but when you really need something the price is a secondary concern.

We did a full Thread on CHICK's on this website last year, under CARS AND PARTS FOR SALE/TRADE/FREE. We titled it 'JUNKYARD PARTS CARS' and it's found on page#4 of that Forum, dated April 2008. Some good pictures included in the thread.

Chick's Used Auto Parts
403 N Cherry Street Ext Wallingford, CT 06492-2310 -
(203) 269-5836

*(I was unable to cut & paste the Google map to this site. CHICK's is directly WEST of Barbarino Nissan, which is on Rte#5. If the RR tracks weren't there, you could walk directly West from Barbarino's Parts Dept into Chick's junkyard. You should bring it up on Google Maps and view it from the air ~ it's huge. It covers many acres on both sides of Cherry St Extension).

Ya know, Vag ~ this looks as if it's gonna turn out to be a 1st-class job when you're finished (IF you're ever 'finished' :lol:) What do you think the car will be worth when you consider it "done"?
