Hello all,
As a mentioned in my introduction, I'm considering a Z22SE to move my oldie (Astra MK2) project.
I have not many premises in this build, but there are a couple of them. One, is to go NA, two is going throttle bodied. I know forced induction is "bang per buck" winner, but it isn't my goal, it's something for pure pleasure, and damn, lot of time since last time I was spending my time with a throttle bodied engine (it was a hybrid B20 VTEC Honda unit).
I don't need to go for top notch figures, the car is heavily modified handling-oriented, and I don't want to ruin it putting brutal figures. I want to be moving in the range of 200 bhp, and also, no need to build a top-end performer at 9000 rpm, I rather prefer to push torque a little bit more to the midrange, it's always more rewarding to drive in most scenarios.
Z22SE and all of those engines are vastly overlooked here in Spain, and I think they can be a good powerplant, all aluminium, modern, and probably very tuneable, but for some reason there aren't many of them squeezed here.
I would like to know about your personal experience/advice on this, since I can take different paths building it.
- How good are internals?
- Can they cope good with moderate power increase?
- Weak/limiting points?
- Do 2.2 work ok raising RPM's, or it worth to de-stroke them and/or use shorter 86 cranks?
I don't want to go for very big displacement (not really into 2.4 conversion, I prefer to keep 2.2 maximum), and they are hard to find here. Z22's and B207's & Z20NET's are more likely to be found.
If anyone can share it's personal experience, it will be appreciated.
