No, turbo spools up, and depending on your compressor type/size/trim that will vary. Don't ask cuz I don't know anything about turbo internals. I just know how it relates to the engine. It's not like an on/off switch, but the level of boost depends on how hard you are leaning on it... cuz the wastegate is pressure/vacuum operated, as is the BOV.

 

A lot of work is necessary for turbos.. You can't just slap a turbo onto a stock motor and expect h22/type R results. Turbos are generally meant to go above and beyond the easier methods of power gain. You'd need a strong D series motor to handle 10psi turbo.

Turbo also results in reliability issues, while an h22 keeps honda reliability by being a stock honda motor. Plus, you can easily place a turbo on a h22 civic.. plenty of room!

 

Smaller turbos can spool @ 2000 rpm. because it wouldn't take as much to spin the turbine. You can prolly reach full boost by 6-7k. Prolly rip through 2nd & 3rd so you'd want to put that power to the ground w/ a Quaife LSD like BB suggested.

With built internals you can spank the H22 lol

 

What is PSI? what does it stand for?

 

pounds per square inch - measure of pressure

 

14.7 psi = 1 bar right?

 

That sounds about right that's what a stock WRX pushes

 

you can prolly expect 1psi = 5whp

depending how well you tune. air/fuel mixture, injector pulse yadda yadda you'd get more bang for the pound...its pretty safe to say that (at least) 5whp is the equavilant to 1 psi.

 

H22A is a bit on the expensive side. The complete setup with parts will be under 4000 but then motor mounts are required which run aprox. 700 than to get it properly installed by some like Rick at RT motorsports it is like 1700 including OBD1 conversion. Then you have to spit out another 300 for custom axles, so for a good complete install you have to spend somewhere near 6000-7000 done proper.

 

So what's this PSI thing? What does the reading represent?

 

this not good enough

 

Compressed air that your shoving down the engines throat.

It takes air, compresses it through a turbine (turbo) so the air is more dense....then through a series of pipes...since the air is hot, it may need to go through a intercooler (big *** rad, depending how much PSI you are running) then more pipes connecting too the Intake manifold.....then boom more power.

pounds per square inch...
pressure per square inch...

...of compressed air.

Anyone care to elborate on it some more please feel free, tis the basics

 

OK sam u talk the talk but can u walk the walk...well have to line it up...and see if there is a replacment for displacment???..

True, but a boosted D16 makes WAYYYY more torque throughout the powerband than a B18... I think even more than an H22 in most cases. Bottom line is, you will get spanked b/c the area under the curve is much more useful, that is if his susp is sorted out to put down that much power.

 

 

Car with more torque will go faster or what exactly does it do? More power at the start point?

 

It's not any one point... peak hp does not interest me at all... I look for a nice area under the curve... a curve that is smooth and fat, builds from 3000 rpm and rises steadily means a good running car. That will me more of a pleasure to drive than a car that just spikes at 6000 rpm or something. Torque and HP are mathematically related... one measures work, the other measures moment. You can read more about torque on scientific sites and stuff if you are interested in it. Basically, it's the ability to turn an axle (well, that's the part that matters to us anyways )

 

Torque is how hard the engine will twist the axles. Horsepower is how fast the engine can spin the torque...

 

So, how do you increase torque?
