how if possible 2 add 30kw to a d16a8 on NA

[lilcrx]

i was reading wikipedia to get a better compression rate change the current d16 head with a newer model d16 head it being stock should bump up the compression rate. u could place a full exhaust with low restrict cat/extractors/cai/skunk tb/port polish/ecu change or maybe run a apexi safc/change the cams/tune up........but then again all those parts for a d16 engine come from america but u might get the power gains u want doing that $5k is more than enough to mod the engine.

there are a lot of ways to change compression ratios. head to http://www.zealautowerks.com/dseries.html for the number of possible combinations from the honda parts catalogue alone.

@GoharD - i have the setup i described, except with a milled head, stage 2 cam, and twin carbs atm (soon to be quad), and it runs well as a daily, and does a brilliant job at keeping up with my boss' evo3 in the hills and on streets.

SeverAMV, but is ur engine the same as mine? coz mine is dohc d16a8.
im not very good at building engines but if its a job not involving too much time most of my friend can probably do it for me.
so say all that required for wat ur running, how much roughly u wrkn it will cost(under 2k?) parts n then labour. coz if labour are too much then i guess i will have to forced myself to do it lol.
much appreciated man, very helpful info

ahh, mines on an sohc d15b4.

for the parts packages i described before it would be 1.5k, but since you'll need two cams, might cost another 500-600 more, depending on the situation. best bet would be to ring up bisimoto, because i think the best bet would be to send your cams over for a regrind since dohc d are rare. will probably cost a bit cheaper than paying him to find a used cam. so you might be looking at 2k for parts alone. if you and your friend can put it all together, you can spend some extra money on milling the head or decking the block to get some extra compression (if you bring the pistons to deck height, CR would be somewhere around 13:1-15:1).
then you would still have plenty for a tune. not sure how much hondata chips cost but you'll probably either need a hondata for a full retune, or an apexi afc piggy back type system, depending on how much you want to spend.
best bet would be to confirm all the prices before buying parts if you're tight on cash.

my build was much cheaper, mainly because i tuned the carbs and ignition timing myself.

There is a certain D16 with about 90kw atw. Stock head just with high comp pistons.

WOW! I/H/E aswell?
Any other mods?

well if you have $5k to spend you CAN drop in a b18c, its prob the smarter option as i wouldn't waste money tryin to get more power out of a D16 (without turbo charging it)

or alternatively, just sell your eg, put the $5k on top and just buy yourself a late model DC2 Vtir beautiful cars!

...and a turbo hanging off the side ?

90kw at the wheels from a 1.6 with 96kw max at the fly standardis interesting. Is this in a city shell ?

^^^Whats with the Honda City OH in-joke?? i always see sarcastic posts related to a city lol.. something we missed?

[bennjamin]

dw its old news. Summary is a member posted one up for sale with very questionable mods , power rating and a very optimistic 1/4 estimate.

back on topic....30kw onto a d16a8 is doable with alot of money in the head and pistons.

[GoharD]

damn, true wat most of u say.
i guess i better off leave it as it. LOL
leave mods for the evo instead
