it's gay

 

no way that's gonna come with a turbo

 

Wow Great post

 

Honda's B18C can get boosted to high heaven. Its an Al block...the question is if Mitsu. will really beef up the structure of the motor.

Anyways...what I would like to see is a DOHC VVT head redesign for the 4G63. Look at the torque monster the Subie motor became for the USDM Sti.

The EVO's 4G63 still gets more torque per liter than the Subaru STi. Anyhow, it will be interesting to see if the next EVO motor will be based off of the 4G69 MIVEC.

 

The Mitsu. is a torque monster, after boost. Any little bit to help climbing the wall to boost would be a plus in my book. Look at the success of the 2JZ with VVT-i, and Skyline 2.6L motor with whatever Nissan called their VVT.

Before speaking...learn what you are talking about. To boost Honda engines high you need to have them resleeved. This cost's money...take a look at the price for a fully built B18 to handle 30PSI vs. a Buschur Stage 3 ($3K).

 

ahhh.... did you miss the missing 1/2 liter? the 4G is still a better motor.

 

Mazda has their engine in the 3 orineted that way too....header in the back, intake manifold in the front....
on a side not I noticed on the Mazda 3 the air intake pulls air into an inclosed battery box, then into the engine...weird.

 

i just had a thought...

is there any possibility this is the engine that will be used in tandem with an electric motor, such as in the eclipse concept e? it makes sense to be that the block be made of aluminum in this case, to save weight.

as for power, a 460 hybrid drive system ought to be sufficient wouldn't you say?

either way, i'm really glad mitsu is being more innovative as of late. maybe this, mivec and other improvements will help revive the company and keep the hopes for more evolutions alive.

 

Ok, ok, do I need to get very, very, specific in order to keep the TROLLS away? Let's talk strictly the bottom end...The B18C5 motors have been able to withstand 400+hp. without sleeves, on pump gas.

Yeah...its not a 700bhp Buschur Stage 3 wonder. But then again the B18C5 revs. to over 8500rpm...stock.

Why can the B18C5 take a 'moderate to high' amount (18-24psi) of boost?...because of the webbing and girtle design build for the main bearings. If Honda could do it ten years ago in Al, Mitsu. is probably able to do it now. Steel is nice, but "high-tech" Al structures are rapidly becoming the metal of choice for a lot of mechanical systems.

Let's assume also if you were to source a B18C5 longblock, and send it back for sleeves and shortblock prep. Then buy a Mitsu. 4G63 longblock and send it back for shortblock prep. (aka buy a Buschur Stage 3) ... you'd probably be a little less on the 4G, and put the 4G in "which" chassis before the EVO 'finally' came to the US?

The reason the B18C5 became so coveted was because you could build it up, and stick it right back into a really good chassis...just as...the 4G63 is becoming coveted 'again' is because the EVO is such a killer driving platform.

Al is what the big car manufactures are playing with RIGHT NOW! Many vehicles are coming out with it, and for that matter Fe block designs are numbered, and phasing out. So...we can whine all we like, but if the 4G63 is eventually replaced, I really, really, really, really hope Mitsu. puts an Al block together in such a way that we all can have some fun getting 'more' power out of it with the least amount of cost.

I'm not touting 4G as a 'bad' motor in any way. In fact its a technical marvel.

<Flame suit on, just in case.>
