Ancient thread.

Why chevy is still using the 350 block? It's very cost efficient. It has been around for the longest of time. If they want to modify something, it'll be headwork, and the rest is pure profit.

if you were a chevy exec, look at the profit margin. R&D cost (very low) + truck sales + crate engine sales + aftermarket GM stroker kits and what not and parts = more money than most JPN-ese car manufacturers can muster in a quarter.

What about the 305 block from Ford? They have given it up (by default GM won the battle for bigger displacement) after their CEO announced for a more global streamlining of product. Their modular engine series are more cost efficient and emission friendly to produce than the 305 block (don't know how, except on the latter).

As for Mitsu, the G6x block is pure profit for mitsu. Why mess with the formula? As for a V6, you can bet it will be either a 6g72, 6g74, or 6g75 (3.8L?? - don't know the coding). No new engine family there.

 

They don't.

 

Wow, the thread that just won't die.

Good ole Mitsu is down to just two core engines that make up the bulk of their whole lineup. They seem to have put all their engineering eggs in one basket with the 4G63, but only for one car. Yet Subaru rolls out the STi for which rumor has it, only for one year, and starts to mix the EJ257 into other cars before it fades away. I would have hoped for either the 4G63T to show up in other applications, or maybe a detuned turbo '4G9 series.

However, if the 4G69 is to be the "world" engine, I hope it has plenty more potential. My first impression of the the '04 Galant with it was okay, but only adequate. I will reserve final judgement when I can get aholt of a 5sp Ralliart. Maybe there is a hotter DOHC version of it in the wood works, maybe this version can produce a lot more. Hell, the Galant had TWO precats under the manifold and lord knows who many under the car.

I just think that not only is the Evo's time short in this country, but so is the 4G63. Mitsubishi's future is probably not going to be turbocharged.

 

Not in the recent modern times. They are slowly phasing the design out with their vortec design.

Also, they still sell enough crate engines to make a pure profit. Not even Ford sell enough of their 302 crate matching the sales of GM. I don't know of enough Mopar's popularity.

 

Yes they do, up till there demise the F-bodies use them and the Vettes still use them to this day.

 

Incorrect.

The LT1 was the last 350 that Chevrolet produced for use in an OEM vehicle.

The LS1 in the 1997+ Corvette and 1998+ F-body was a completely new design. Nothing between the LS1 and the older designs is compatible. The LS1's displacement is also only 346 cubic inches. Completely different. Not a 350. End of story.

 

Dir yes dir

 

That's kinda amusing that on Chevy corporate site, they still list their small block V8 as being 350.

 

They're allowed to round up, I guess. Old traditions die hard. A 2.0L 4G63 sounds better then 1997 cc's it really is. Ford had at really bad because I don't the old "5.0's" were really that at all, even if you rounded up (but rather down like they were supposed too).

The last true 350's were in the G vans, Chevy Express and GMC Savanna. Up until '03 I think.

 

Ford had their 302. GM had their 305 and 310 or something around there.

What about the 427 or 454? For CI, rounding up doesn't sound all that appealing.

Import using CC's had to round up. Marketing would be a nightmare to say it like a motorcycle.

Salesman, 'Yup, this a genuine 1997cc eclipse."

 

Yeah 302 is more like 4.9L. But even still 350 is a household name when it comes to Chevy, and just sounds better then 346. You get that sort of oneupmanship with the domestics, Mopar's 426 Hemi, Chevy's 427 and then I think Ford's 428 CobraJet. Back then they weren't into rounding up I guess. For some reason certain numbers become legendary because of the cars they were in. Most people love the 454 Chevelles and that big block stayed around forever, even into today. Whereas the 455 Olds Rocket blocks, Pontiac Super Duties, and Buick 442's didn't quite get the notoriety. The 427 from the old L88 Vette made it a legend too.

Maybe someday 2.0, 1.6, and 3.0 will be legends, and we will just ignore the "2000" stamped on my valve cover.

 

121 cubic inches of whoop ***!

 

See that didn't sound too apealing doing the CI route.


The 1.6L is already famous. It conjures up images of the B16 motor.

The 2.0L is already in the arm of the G63T. there's no doubt in my mind.

When I starting to think about the +3.0L motor, I immediately think of GM's V6's. For imports, it's the supra.

 

I my humble opinion the 4G63 should stay. After all it’s a dam good engine. On the competition front, if Mitsubishi went for an aluminium block like most are running at the moment, it would not be half as tuneable and reliable as they are now, even if there was a weight advantage. And how dose the old saying go “you have to finish to win”! I say keep evolving the current unit (Ti valves and better head designs) and reduce the weight of the unit where possible. On the capacity front, why go for a larger than 2.0ltr? if you are keeping the turbo what is the point? A V6 of 3.0+ltr will weigh more than the current unit anyway, and not perform as well anyway!

 

the 4g63 is an old design, its starting to show. sure you can get hug numbers out of it. but look at what other manufacturers are doing. honda w/the s2000, the new k-series stuff. the new gm ecotec engines. the 4g63 cant compete. the new 2.2liter s2000 lays down damn near the same power the evo does and its NA.

i have always felt that factory turbo cars replace technology with boost. if they put some new technology into the evo 350-400 hp would be easy.

the strap on highy inefficent turbos, stupid ammounts of boost and it is only rated at 271hp. most greddy turbo kits for hondas come with a tdo5-15g, at 10-12 psi a b16 will make close to 300, why does it take so much more for the evo to make that. i mean, 21-22psi. on a proper turbo thats over 450-500 in honda terms.

look at bmw's they make over 400 on 12psi.

not to mention the horrid gas mileage of the evo.

if i wanted to do a study in inefficency id pick the evo.... or maybe a wrx, sti or not. they are all crude ways to make crap for power
