engine swaps, builds

[Slick1100]

I've seen lots of talks about the 2.0 and 2.2 engines and the NA, turbo, and twin turbo variants. I realize there's more power to be gained from one of the turbocharged variants, but I'm a guy that likes torque. Especially down low where my automatic can use it. Turbos are great for Hp, but the added power is much higher in the RPM range than my car normally sees. Can a 2.2 NA engine be built to produce more torque? I ask because I have one that nobody seems to want parts from, so I've been thinking of rebuilding it. The flat 6 seems like the right idea, but they're hard to come by, and might be physically impossible to fit in my engine bay anyways. Just thought I'd post this and see what ideas came up.

More displacement?

Dont misunderstand, just because turbo gains are more on the high end a 2.2 turbo has more torque at all the important rpm compared to the 2.2 na

Stroker kit.

[Slick1100]

Ok, a stroker kit definitely adds torque. I have found that MRT has a stroker crank. As for the comment about turbos, my engine rarely gets above 4k RPM, except when I'm passing, especially while on one of the small mountains around here, or accelerating hard from a stop. My understanding is the turbo really doesn't kick in until 4k. Is this right? It would make more sense to me to put a supercharger on, thus eliminating the lag and need for higher RPMs.

I think you need to learn to use the accelerator. These engines love to rev. You've probably built up a bit of carbon in there.

as far as i know,correct me if im wrong,the ej22 has about 118 Ft-lbs of torque at i think something like 5200 rpm 130hp around the same area.but the ej22t has 189 Ft-lbs at 2800 rpm and 160hp at,im not totaly sure on this either,5600 rpm?now you might not have as smooth of a torque curve with the turbo but it will pull much harder through 4000 rpm and be much quicker then a n/a 2.2.i'm pretty sure on the torque and hp numbers and i think im pretty close on the rpm's.if im wrong please someone correct me.

[ciper]

If your engine never reaches above 4k rpm then you arent even hitting peak torque, let alone peak hp! Peak torque is at 4400!

Not at all.. I find that the turbo is nearly out of breath at 4000rpm.

[Legacy777]

the EJ22 n/a makes 130 hp @ 5600 rpm and 137 ft/lbs of torque @ 4400 rpm

[Slick1100]

Interesting figures for torque and Hp. Like I said, I don't get above 4k unless I'm passing, etc. Not to say I haven't hit redline , but the automatic keeps the revs low in normal driving. Say in the 2-3k range. I'd like to have more torque so that the tranny isn't shifting quite so much to get to the power in the higher revs. Sounds like the way to go with this engine is the stroker crank and a turbo (assuming the crank can handle it). If I only had a manual... but that's another can of worms all together. Thanks for the info though.

As mentioned before, you won't get any power out of these engines unless you get on the revs. They're not the same animal as the larger engines back in the day.

The control logic on these automatics leave something to be desired IMO, but if you want more power, just floor it.

[Brat4by4]

You want the EJ22T. Not some EJ22 with a turbo slapped on. The t is built hardcore. They have 181 lb/ft. at 2800 rpm, the turbo is a torque machine. This is more torque than any NA could dream of. You are stating general 'over-sized' turbo characteristics. The largest turbo you could put on this engine wouldn't have that much lag.

In reality the turbo starts pushin at 2000 rpm, not much but it's already outpulling any NA engine. You start feeling a rush by 2800-3000 rpm because you're hitting peak torque... then it really starts to scoot by time you hit 4000. I think what you really want is a Chevy 350 Crate Motor... they're only like $1200 from a GM shop and they put out 300 horse and gobs of torque. Then you could get away with just 2 or 3 gears.

Now you're talkin... V8 Legacy, Hmmm I wonder if its possible

[vrg3]

Well, one nice thing about a turbocharging an originally-naturally-aspirated EJ22 is that you maintain a higher compression ratio. When it's off boost, the EJ22T is a bit sluggish. Like everyone has already said, that's not usually a problem because if you drive right it's easy to keep it on boost. But still, it's nicer to maintain decent behavior off boost.

Now you're talkin... V8 Legacy, Hmmm I wonder if its possible

I have always wanted to drop an SVX motor in a BC-BF. Sure it's not a V8 but it is considered to be Porsche-like in its smoothness and power delivery. I wonder if that would fit ...

[Legacy777]

It's been done, I believe PDM did it. It was also supercharged.

I believe so too, i remember seeing a picture of it somewhere..

What do you mean down where your Auto can use it? Suby autos shift based on throttle position... I visit redline frequently for mine. as for the carbon buildup, you can get a water spray bottle, and lightly spray into the intake with the motor running. the water steam cleans the combustion chamber. same thing for water spray on a turbo engine.
