Now why exactly is the j-body only capable of producing 300-400 hp tops when there are other cars out there (namely skylines with the RB26DETT engine) producing 1500 hp? Technically if one motor can be modified to produce over a megawatt, then can't ours? I just don't really get this, plus I'm aware that the RB26DETT is a ricer motor and produces less torque in comparison to our engines if our hp were comparable. What do the ricers got that we haven't got?
An RB has more displacement, therefore more power potential. You don't see top-fuel cars running 3-cylinder metro motors do you?
There is also the engineering that goes into the motor from the original design point. Motors that are built with a 'performance' intention get cool things like larger oiling passages, thicker crankshafts, higher alloy materials, larger journals, 4-bolt mains, and main girdles. All this is not within the budget for a economy motor. Luckily, with the right equipment, all of this can be fixed. GM has put 1400hp through the ECOtec, and there was a Quad motor back in the early 90s (?) that made 1000hp in a top speed car.
How much $$$$$ do you have? That's what it's all about in the end.
For more information, put down that Super Street magazine you're reading and pick up a book on performance engine building.
fortune cookie say:
better a delay than a disaster.
the GM drag car with the ecotec has over 1200 hp in it and half the engine is stock. so it can be done. it all depends on how deep your pockets are
Im a Xbox 360 fanboy...and damn proud of it!!
Wow, so it's just that our engines weren't originally made from the gound up performance, but low cost? So all those small things really do make a difference. It's just hard to imagine going from 100-200 hp all the way up to 1000+ by lightweight pullies, exhaust, twin-turbos, and better internal workings. That has got to be some serious cost and labor. That sound about right since the fully modded skyline I was talking about had like $100,000 in it and no stereo. lol. But it is possible to get to 1000+ hp with these then? Seems like 300hp is just the place where it stops being cost effective and you'd be dropping more money for less hp as you go up.
Any engine can make a alot of horsepower, it's just a matter of what it is the weakest link in the chain. As was stated above, RB series motors where made for a performance car. Ecotec and Quad 4 series motors where made for an economy car.
Look at what will break first and how much abuse that one part can take, that will give you the limit of what an engine can make.
also we unlike stock boosted cars dont have forged internals and all the goodies stock boosted cars get.
Not meaing ne disrespect and watnot, but ur comparing a Skyline's RB26DETT motor to our economy engines...that doesnt seem like a good comparison considering the RB's are 6-bangers n ours are 4, RB's are come factory turbo'ed...which gives them better internals....n alo the engineering ad technology put int the motor. A better comparison woul be either sum Hond engine or maybe even the 240sx KA24DE engine.
like everyone else said, with the righ equipment you can take a low-powered motor n make it have huge numbers.
no more cavy...now 240 =]
I see a cool-air intake
It's got a NOS-fogger system and a T-4 turbo
I see an A.I.C. controller
It has direct port nitrous injection
Yeah, a stand-alone fuel management system
...Not a bad way to spend $10,000
First I would exactly compare the Skyline motor to Quad4/Twin Cam or Ecotec motors.
That's a bit like comparing the LS7 motor out of Z06 to the Ecotec motors - their not in the same class - in power or displacement. And better comparision for Ricers to the Quad 4(including the TC), or Ecotec motors is the inline 4 motors of Honda, Toyota, & Nissan.
And IIRC - The 2.0-2.4L Honda motors, the 2.0-2.4L Toyota motors, and the 2.0-2.5L Nissan motors, all a similar capabilities as the Ecotec motors - to run up to 300-350hp on stock internals. With upgraded internals, as well as boost & juiced - 700 to 1,000 is likely possible with these motors. So GM isn't really behind these companies in potential performance capabilites of 4 cylinder motors.
rb26 and LD9 is apples to oranges.
that motor is 6 cylinders 2.6L and boosted from the factory
Working on obtainting an M-Class license... ?? Hint: 2 wheels.

correction..the quad4 for was MADE for showclass racing..and broke records in its day
but he is comparing the wrong engines to his own..everyone is right listen to them..if you want that much more power youll need a better built engine from the factory
Botoom line is. Why waste cash making your cav fast??? Import in a already fast as hell JDM car for 10 grand CAN into canada.... and be done with it!
heres a general idea of what your looking for....
2.2L/2200...A-B motor..nothing more
2.3L Quad 4...^^^+ SCCA/Touring racing (N/A)
2.4L....A-B motor (street only successor to the Quad 4)
Ecotec...^^^^+ GM's new 4cyl drag motor...by far the best potential of any J motor
no J motor was ever meant to be very powerful in it stock configuration. now any of these can be built to make pretty goood power, but the ecotec was the only one designed from the start with huge horsepower in mind, however, that is only after extensive reworking. the block, head, and main bearing girdle have held up well over 1000hp. the rest blew long before that. last i remember HY J-bodies had a full article on GMs R&D on the engine...its worth a look.

But you can get forged internals in J-body motors. Not from the factory of course... but you can get them - and they really arenb't that hard to find at all. It is expensive but not THAT expensive(consider what you would pay up front for a real performance car + the additional insurance). Once you get forged internals, the potential power ceiling goes way, way up.
I've never heard of this "part throttle" before. Does it just bolt on?
