i just bought a 93 civic ex a few weeks ago and im kinda puzzled. the engine is a b20z with a gsr tranny and gsr intake. The manifold is from a ls integ. I dont really know what types of upgrades to buy. Like if i should buy parts for a civic or an integ. since the parts are different. If anyone can help thanks a bunch.

 

what do you want to buy.......

 

um like headers and intake cause i already have a thermal catback exhaust and high flow cat

 

You can buy any header made for the B series engines. Keep in mind that you will need to modify the catalitic converter or use a test pipe for everything to bolt up. The lengths will be different. You can buy any intake made for your Civic.

 

thanks for everything, if u have anymore ideas im open

 

I say grab yourself a p72(GSR) cylinder head.

 

OH YEAH!!!

 

Order parts for an LS...the only major difference between a b20 and an LS in the bore... LS/B series headers work and there is no difference in lengths.... Everything bolts up... U dont need to get a test pipe or a different cat for it to fit
