3SGE NA Max power potential

[Lunchie]

Hey i was just wondering what sort of power can be made using the 3sge in naturally aspirated form and also if there are any companies which make parts specifically catering for this purpose.

Yes i know its much easier to just turbo it... but i feel that NA cars have a degree of purity about them

Cheers

Probably around 300HP maybe a bit more, but it'd cost $30k+ to get there, and you'd destroy a few engines along the way.

Just go get yourself a tezza, youll be happy, trust me.

Could go get an mr2 turbo, but youll kill yourself

im using a beams 3sge ,12to1 comp longer rod ratio ,lightened crank 520 thou trd cams and trd quad throttles and extractors and vvti enabled with a motec m800 and im making around 163kws at the back wheels power is from 3500 rpm to 8700rpm and a flat torque curve from 4000rpm to 8800 and im still using 98mobil fuel total cost of engine with all the parts about 15000 aussie including the motor

DAM... thats tasty..... i dont know why i just love NA engines.... do u happen to have any 1/4mile times on that car?

LOL, I was just about to say.

Ask Celica RA45, or dodgy.

But I got beaten to the punch line.

I would say 220-250 flywheel HP is relatively easy to obtain on a sane budget, if you start with a beams engine.

Im not sure about earlier gen 3SGEs though.

[strx7]

that 220-250hp is 'easily' obatinable on a 3rd Gen 3SGE too, they put out 175HP std.

[RomanV]

Well thats debatable.

I havent seen a gen3 3sge in person, only a Gen 2. but the money you would save buying one over a redtop/blacktop 3SGE would be false economy IMO. I mean you need to spend money just to get it up to the amount of power that the VVTI motor makes in standard form. And then you are going to have a peakier engine, whereas the VVTI motors retain a decent spread of torque.

As Celica RA45 has stated before, he has some crazy cams in there, and the car still idles like a street car.
This would be impossible to acheive with a gen 3.

My redtop 3SGE has a port and polished head and some aftermarket extractors, should be good for 210 flywheel HP perhaps? I dont know to be honest. Well hopefully at least the factory 200hp anyway.

The redtop 3SGE intake manifold is superior to any cast item.
Its made from pressed steel, with tubular steel intake runners, that flare out to bell mouths inside the plenum. I bet you would have to spend a fair bit of money to get a cast gen 3 manifold to flow as well as that. Unfortunately I cannot comment on the head, as I havent had a chance to have a good look at it yet.

Since I will have access to both motors in peices, I am going to bust out the digital calipers and document the differences I can find between the redtop and the gen 2 at some stage. I might even produce a cad drawing or three.
Because there doesnt seem to be much redtop info around on the net.
No doubt I will post my findings on here when that time occurs.

Haha. If you want good atmo power you'll need more cylinders I reckon. You'd have a better power spread as well as the cylinders work in time closer than a 4 pot. Just do a bit of machining with a crankshaft and some other work (well actually a bit more than that) and who knows you could end up with a V8 6SGE . It would sound mint too. Or what about using a 2JZ non turbo with a 1JZ non turbo head. Apparently because the 1JZ was Yamaha designed it had better porting ect. And with a 2 JZ well we all know what they are capable of. Anywayz good luck with the build dude.

i got 109kw at wheels on my gen2 3sge with just itbs, exhaust, and 25deg total timing.. megasquirt for fuel..

got a heap of my gear on trademe atm.
