I've been wanting to boost my 91 civic for some time and I've been very
frustrated. Please help me out.

Can someone please point out the best route for upgrading my D16Z block to
accept a moderate to large shot of NOS with a mid-sized budget, say $8k. I
am not interested in turbocharging right now, strictly NOS. Please focus
this attention to the block (pistons, rods, sleeves, crank, cam, etc) and
ECU. I am wanting 250+ hp overall with *NO PROGRAMMABLE ECU* (no hondata,
no neptune). I am however interested in replacement or modified ECU's that
retain the stock config with a defeated (or increased) governer and
revlimiter. Mainly I want quick RPM's and a major increase in midrange and
high-end torque. I also would like some reliability. Any ideas?

Thanks for your input

makes no sense. stock ecu but more power??? no programmable ecu but
replacement or modified ecu's ok???

and why nos??? if you just want to drive in a straight line for 15
seconds, buy a ford. you can't use nos out on the track.

Stock ECU configuration because I want it tuned to run basically stock
whenever I'm not using the NOS. But I would like the governer and
revlimiter increased. NOS instead of turbo because I don't want boost
all the time. I don't want that extra strain and power when I don't need
it. Sure, there are turbo controllers, but there is still a minimum
boost running all the time. Furthermore, I don't feel like hassling with
dyno tuning.

I'm sorry, let me elaborate a little more... I'd like a quick, all-motor
engine MOST of the time. Something that builds up RPM's fast, with a
reserve of a considerable NOS shot when I need it. And I wouldn't get
much benefit from upgrading the valvetrain if the stock ECU's revlimiter
is going to prevent me from peaking 6.5k RPM's. Otherwise, the stock ECU
is fine. I'd also like the governer defeated, but it's not necessary as
I probably wouldn't be taking advantage of this very much, but I'd like
it anyways.

anybody suggest starting with an engine swap first say to

B18C (-R)
B16A
B16B

at least then you will cover lots of factory HP ground to your 250+ hp mark

that is you are starting with D16Z (120 hp) where B18C-R ( 195hp) so thats
75 hp for about $1500 maybe not as impressive as 250+ out of a D16Z but ?
easier ?

Whatever you do, your '91 engine has to come out, and you have $8K. Don't
bother with the D16: get a Prelude or Integra B18 VTEC (with the manual
transmission) and rebuild the lot. Once its all ready, along with the brake
and suspension upgrades (you ARE going to get better brakes, right?),
exhaust etc , take all the old bits out and do it all once.

you're kinda stuck. the best non-turbo way to make more power is to up
the rpm's, and that means work on the crank, con rods, pistons and most
of all, cams. and you need an ecu with a raised limit. there are stock
jdm ecu's for the 91 sir crx which go higher, but it'll be hard to get
one, and i doubt it'll pass smog here. depends on which state you're in
i guess.

as mentioned by others, changing the motor is an easy solution.
regarding ecu's, i have seen a site showing how to program/re-flash your
old ecu memory, but you need to know what you're doing on that one.
have a working spare handy just in case.
