I think it's funny to whine about how this stuff is nothing like OEM.

Go look at a top fueler. Or F1, CART, IRL, Lemans. Or just about any high end motorsports. You won't find any of them using OEM parts.

This type of stuff may be out of yours and my budgets, but so is Top Fuel yet I'm sure you'll see a whole new generation of Professional Motorsports spawn from this type of work.

Am I going to run Beryllium pistons in my street car? No, but it may help somebody introduce a fully strutted piston capable of handling the power goals I have while being reasonably priced and letting me reliably spin to 10k RPM. Will I buy a billet cylinder head? No, but somebody might start casting a new head that can kill a full blown $5000 EVO head in stock form for $1000. Progress is good in this case.

 

The thread is titled "Highest HP 4g63 engine" and when everything is custom made I have to wonder what left of the engine is 4g63? Never-the-less your work is very impressive and look forward to seeing the outcome.

 

This is where I stand. Impressive work, but this is NOT a 4g63 engine. It may have the same measurements but it's not the engine that rolled out of Mitsubishi's factory.

It's funny cause I was just thinking similarly. At what point is it not a mitsu engine anymore...I mean redesigned billet block and head, just seems like a custom 4cyl engine.

Not trying to take away from your work because it is amazing to say the least but it really kinda takes the fun outta pushing Mitsu engines to the max.

 

I couldn't have put it any better! its people like this that change the tuning world. I would love to see someone cast a new head. Its been done a million times on the Domestic market, so why not on a Import?.....

As for the comments about it no longer being a Mitubishi engine, well can you say a 4G64 engined EVO is an EVO engine?.... I guess i dont really care what powerplant a car has if it fast and powerfull! lol Whats the point is running an engine that wont meet your goals if you can swap it for one that can? lol

Well the whole 4g64 block is one of the reasons I didnt wanna do a 2.4 to begin with. And I'm not saying anything about him making a fast car like I said I think its pretty ****in pimp but the fact remains he is claiming highest horse power 4g63 but its not a 4g63 at this point.

Its just food for though, when does an engine no longer become the engine you started with?

 

When parts developed for the OE engine no longer bolt on.

 

Does it really matter?

The program started as a 4G63 and as it developed, it morphed into something much greater.

I guess when they set a record using a motor that was developed out of their 4G63 program, people have a way to discredit what they are doing?

 

Who's discrediting?

Thats the problem with this site as soon as someone as an objective opinion everyone ****s bricks. First off it was a simple statement one in which I even said what they are doing is awesome. Secondly who the hell do you think you are to get offended for Spyro?

Taking a comment that wasn't made to you or for you personally is a little odd to say the least.

 

what are you guys talking about? A 4g63 pure would only be a stock block, uncammed. That would be a true 4g63, 100 percent bone. Pushing that to the max would be it. I'd call this highest "tuned" 4g63 car. Just like a buschur, etc. those are tuned with different parts. Either way, he's pushing the 4 cylinder engine world to another class. Titanium cranK!!!!! Vanadium bolts wtfff!!! lets see those bolts and crank spyro!!!!

and who else thinks that you may dislocate your neck when you hit full boost at 100 psi? if you move at all the whiplash may crack a neck bone. license plate should be "fearmyspool

 

So my SBC (small block chevy) with Dart block, forged internals, AFR heads, custom EFI is no longer a SBC??? Same thing goes with the BBC or any engine with aftermarket block and heads. Its the same principle, design and dimensions. It still uses some of the factory parts. Its a 4G63 in my book. Nice work!

 

I know what a SBC and BBC are lol. Anyways it was just a question, one in which was answered by Aaron and I think its a pretty good answer. If all the oem accessories bolt up to it then cool.

I only brought it up because that billet crank doesnt even look like a 4g block to me.

 

the small block chevy needs billet parts to be impressive. the 4g63 proved to be the most potent engine (hp/ltr) on the planet without billet parts.

now that spyros has remade every part of the engine with F1 and space age materials he is on the same playing field as 4000hp norwood 4cylinder engine.

will his efforts compare?

I am entertained. but that is it.

 

Is that the same 4000 HP drag car that has never ran down the track at a public event?

I'm not talking ****, but I don't think that car has run anything close to the time a 4000 HP 4-cylinder would deliver.
4000 HP is top alcohol territory and I don't think he's even broke Rau's time.

 

I think the purpose of this build is just big numbers on the dyno only, not really track performance or anything.. they are after more record breaking numbers.
