I have a 91 CRX Si but I'm a bit hesitant on what mods to buy, knowing I'll be swapping in a B16A in a few months. For example, can I buy an Exhaust, Intake Etc.. and keep them for when I get the B16A..?

 

suspension, any thing on your suspension. new crossmember so you wont have to bend your other one. wheels, tires. i dont knoiw the engine stuff so ill let someone else handle that.

Yep, exhaust, intake, and cat. Dont get the header till the swap (99-00 civic si). Ryan

 

So the exhaust I get for the current stock engine in the Si will fit perfectly when I get the B16A...?

 

yep. Ryan

 

I personally would wait for the intake, the best one performance-wise for a swap is one for a 99-00 si, even tho you will have to do something about the battery because its in the way.

 

don't buy anything that bolts to the engine. but as said before cat., exhaust, suspension, wheels, etc. are good

I'm not 100% sure on the part #'s etc as this is something I compiled about a year ago when I was considering the swap, but I have a ZC not a B16 so some may possibly be off, but for the most part it should be right.

 

These are things you're going to want to upgrade:

Suspension - Heavier engine = more weight up front = more understeer. Get new shocks/springs... lots of choices and combos here depending on preference, application, and budget... do your research. Swaybars are good. Most people get Suspension Techniques or Neuspeed. Suspension Techniques are cheaper and seem to be easier to find.

Chassis Reinforcement - When you do an engine swap you compromise the structural integrity of your car. Strut bars and tie bars will help. You can get any brand, even cheap as hell ones off ebay and places like procarparts will make it better. You may or may not need a new front crossmember... it depends on what you want to do with the car... once again do your research. Motor mounts you will need with the new engine.

Wheels/Tires - All of the above gives you more chassis rigidity. More chassis rigidity means your suspension will easily overpower your stock rubber. Get some lightweight 15" or 16" rims that allow at least 205 tread. Diminishing returns applies and larger rims will most likely just be heavier and slow you down. Don't go cheap on tires. No matter how much you spend on bolt-ons for upgraded handling and power your car will only be as fast and handle as well as your rubber allows it to. Buy as much grip as you can afford.

Brakes - More weight means more time to stop. Upgrade at least the front brakes to at least 10.3" rotors/4 piston calipers. 11" rotors/4 piston calipers would be better but you need said 15" or 16" rims first and it is more expensive. Upgrading rotors and calipers means you need upgraded master cylinder and possibly brake booster. A '90-91 Civic Sedan EX master cylinder will bolt-on to your current brake booster, a '90-91 Integra master cylinder will be even better but you have to get the brake booster with it.

Exhaust except for header - at least 2", 2.25 seems to be a sweet spot, though a lot of people like 2.5" as well if they are doing more than bolt-ons

Of course you don't have to do all of this before the swap, but you might as well get started. I'd leave performance related stuff for last and focus on handling for now. The handling benefits you can enjoy with your current engine, and it's better to worry about the performance stuff after the swap is done and you have a clearer understanding of what you want to do with your engine (just bolt-ons, internals as well, forced induction of some sort, etc).

I would not worry about the engine being a lot heavier, its only about 50 pounds if that heavier.

 

I might be wrong but the figures I've seen (from the resource) are 100lbs heavier for a B16A versus the D16A6. That's like driving around with someone sitting on your hood with the stock suspension and brakes (that's what it felt like before I redid mine anyway, although I have a B17A so I think it's even a bit more heavy).
