so i read something that said Evos have one of the if not THE highest hp/liter ratios of any mass production car. what can i say it makes me kinda nervious when i see truck comercials advertising hp and tq numbers that my stock 4cyl is close to. my Lightning is scary fast and i think thats at like 85hp per liter. so that means our motors are pushed harder than any other stock motor from the factory. this makes me not want to mod my car. speaking of mass production and kinda off topic how many 2003 rally red evos are there?

 

Well, considering there are a lot of Evos running around out there with 400-500bhp (not wheel) on the stock motor, that means it is able to handle 200-250 hp/liter, so I'm not sure why this worries you. The 4G63 has been around since 1989 with the release of the Eclipse turbo...it's a very well-known entity.

 

the 4G63 and the 2JZ-GTE are fine examples of japanese engineered turbocharged engines easily capable of handling up to 200 hp/ltr. Not quite a dime a dozen, but these platforms are best in class and prove it every day.

 

Don't forget the VG30DETT that comes in the 300ZX TT. I had 548.9 Rwhp and 602 Rwtq on stock internals. Thats 183.33 hp/ltr and 200 tq/ltr.

There are some pushing 700+ Rwhp on stock internals. One owner named Sean Wagner dynoyed 750 something with NOS on stock Internals. Now 250whp per liter that is just sick!

RB26DETT another in the same ball park.

 

Very true. I forgot about that engine. SR20DET is another when tuned they are pretty bad ***'d

Best design/built motors of all time (IMO of course): RB26, 2JZ and 3S GTE, 4G63, SR20, B18C/K20

And for the creator of the thread; Cars like this are built with the understanding that some people will mod the hell out of them, its just a part of the market. Take the supra for example; it was engineered to have 600hp but was detuned to about 320hp/"280ps" for emmisions and probably safety. Supras HAVE MADE 1000whp with stock blocks.

 

How much power the car is producing per litre has absolutely nothing to do with being "pushed hard". It just means it can do more with less.

The C6 Z06 makes 505HP out of 7.0L. Thats only 70hp/per litre! Not impressive from an engineering standpoint but it gets the job done! Either way, that reasoning to not mod the car sounds right but in reality, its completely false.

Shepherd's 2.0L 4G63over 600hp+/per litre!

 

I think it would be stable. SR20DETT can

 

2jz probably the best ever. guys were laying down 800+ on stock internals, thats NUTS.
evoNate, your wrong on your own car. its making 91 hp per cylinder, not per liter.
I dont think the sr20 was ever as impressive as the 4g, never see those guys with over 380 or so on stock internals.
how about Rx7's, (13b) easily over 200 per liter, built probably the highest ouput out of any motor, of course this is a different motor and they can blow up VERY easily

 

Good catch, yeah I was making 183 hp/ ltr and 200 tq/ltr.

 

OK for starters it is not uncommon for japanese manufacturors to use forged steel cranks, cams with very high quality pistons and rods from the factory where as american companys use cast iron and cast aluminum peices that cannot handle nearly the same power without major modification. for example look at the nissan sr 20 engines from the early SERs that could take 300+ hp with out dipping into the engine internals then look at GMs "performance" 4 cyl from the same era.... the quad-4. if ya looked at it crosseyed it would blow its head gasket

I think it has to do with culture, the american culture puts the dollar as the most important measure of status so products come out as cheap as possible. japanese culture dictates reputation and honor are just as important if not more so than $$$ so desitions are more about quality than maximum profit. with quality profit follows. for example just look at any tuneing shop that does good work, they are buried with buisness.

 

I don't really think its a cultural difference. Everybody and that includes American and Japanese manufacturers try to build their products as cheaply as posible since its a business. The difference in my opinion is the quality of engineering and what the market is demanding.

Japanese manufactures know people who buy thier sports cars are gonna tune the hell out of them while american manufacturers don't take this into account and therefore leave out a margin of safety.

 

Quit being a sissy and mod that sucker!

 

IMO, the real difference between true japan cars (not ones engineered or made in us) and us cars is attention to detail. I've owned several domestic cars and japanese cars and the difference always seems to be attention to detail. It is the attention to detail that allows these cars to produce so much power and not become a hand gernade or require extensive modification.
The true beauty of the EVO is that it is a $30k car with $25k spent on drivetrain/chassis/etc and about $5k spent on the interior. Sure those numbers are wrong, but most domestic cars have the ratios reversed.
Since I work in the automotive testing field, I am well versed at spotting areas of a car that were cost reduced or have a "patch" because of weak area.
I would make a terrible japanese engineer, but as a us engineer I'm just right...lol.
