i have a 1991 crx dx with a d15b2 and im going to be doing a d16z6 swap in it next month. just trying to get everything i need together before i start the swap. when i swap out the motor should i also swap out the exhaust manifold or will the dx manifold be fine? i dont have the stock d16z6 mani so if i cant use the dx mani i will most likely get aftermarket headers.

 

You can use the original header, that'd be best because you know it already fits your car. I had a problem trying to put a stock header back on mine, and I think there is a difference between the DPFI and the MPFI headers, one is shorter and can't fit the other.

 

i have a dpfi motor now so does that mean i can still use the original manifold with the d16z6?

 

Just get some ebay headers.im pretty sure the d15b2 headers are smaller than the z6 ones dat motors gonna be choking lol

 

thanks for the help. i think im going to order some headers off of ebay. is megan racing decent quality?

 

so i ordered some megan racing headers off of ebay after reading some good reviews. my next questions is is it alright to use a lightened flywheel with a new stock clutch?

 

I would just go with a comp clutch stage 1 and lightned flywheel

 

thanks for the relply but that was weeks ago. i already got the motor and tranny in the car now. why do u recommend a comp stage 1 clutch? i put the flywheel in with a stock replacement clutch set and it seems to work fine.

 

i got a question for u crxblues. anyways which tranny did you used? cause i know the d16z6 is an obd1 engine and you're car if its a 88-91 civic/crx then its obd0.

 

when it comes to the trannies that dosnt matter

88-91 used cable transmisions and 92+ uses hydro trannies so the z6 one wouldnt work since its hydro

 

yeah when it come to d-series trannies it doent matter much just as long as its a cable tranny. unless u feel the need to convert to hydro. i used a si tranny for the d16z6. getting my triming covers today sso i have it running how it should today.

 

ok im just asking to see if you convert it to hydra instead of keeping it cable. cause im planning to convert my 91 si hb into obd1. so i was just wondering thanks.
