Re: 90 si b21 or h22

First off, what do you want from the car?
I fix up cars stock with minor mods so I can't shed much light on stance other than many times it reduces handling. The homey's at the 3g section can tell ya what's do-able as far as lowering goes.

H22 gives you more thrills per minute, but figure $5 grand going in. If that's too rich you can get a little more yee-ha out of a B20 by purchasing a jap version (no egr) and punching the cylinders to 83mm like a B21. I think using the B20 head gives a slight compression boost so you end up with like 170hp. That aint nuthin' to sneeze at in a 3rd gen. A fresh rebuild on the B21 will add a bunch of pep to the car. Study FRM cylinder walls before going that route. They have to be honed proper for the motor to hold up.

The H22 has higher rev capability and that super famous vtec boost at rpm's the B20 &21 are maxing out at.
Now 4ws is the deal everyone clamors for. 4ws with H22 is the ultimate 3g.

Pretty much got flamed for driving like a jackass and was told to slow down. And I'll be damned, slowing down fixed it.

You will sacrifice the slammed look for an H in this chassis, and since I am about performance I no longer subscribe to the old days of slamming my cars.

I am about lowering for style as well as function.

I recommend moving on to the H22 simply due to supply and demand reasons. There are just not enough suppliers or supplys to keep the OEM motors alive, you will find that out real quick that you have to go junkyard hopping just to keep her on the road.

I pushed to get the H22 swap kit produced just so I can keep my lude on the road with more power and better aftermarket support.

Lets face it, you do not get an old car like this to stay OEM, you build it and run it, and since these things run very well, you want to keep the power plant supported.

The initial cost will be high, but after you have spent that money, its all about maintenance and aftermarket support. You will be very glad you did.

Here is the new kit that I now make: 1FunRyd H22 Swap kit - Group Buy - contact me when you are ready to order.


Here is what an H swapped 3rd gen looks like:
