*** D16Y1 - How Far can we go w/o TURBO??***

[B147ch]

Heya chaps,

i'm curious to see how many others on ozhonda have this D-Series Engine and how far they've modded their engines without having top resort to a turbo kit??

Now i know that its debatable that the cheapest mod people can do to their d series is slap a turbo kit on it, but maybe there are people who want to get as much NA power out of this block without breaking the bank account. (?)

I'll start by letting u all know what power i'm reaching with NA Mods to my SOHC Vtec Beast..

ATW - 80kW.. not Bad...

[fatboyz39]

Already seen a d16y1 hit 80kw atw.

All out D16y1 motor build, 100kw atw can be achievable.

[B147ch]

when u say all out - what does that encompass??

[trism]

rrods, high comp pistons, valves/valve springs, flowing the head, cams, intake etc

[90LAN]

how much money do u have that is the question ?

[tekung89]

any more then 100kw NA sohc den i would consider the dyno to be faulty =P nah jks. never seen an all out NA sohc before, wouldnt kno

[SeverAMV]

hmm, according to Trism's description, my d15b4 would be considered all out.

but you dont really need rods, you can mill the head and mill the block down to bring the pistons closer to the head to bump up compression, but with cast iron pistons, i'd try to leave around a 2-3mm gap, or your pistons will hit your valves at around 7200rpm.

and it doesnt cost too much money. will only set you back about 3-4k if you know where to get the parts from and a good mechanic.

an all out build setup and tuned properly with the right ecu can net you close to 200whp. rushi on d-series/onecamonly hit around 180whp with ITBs, and bisimoto went either around 300whp or over it with a pair of dual sidedraught webers and a lot of fluid dynamics implementations.

Bisimoto = So Damn interesting!!

how much money do u have that is the question ?

About 4k...

[fatboyz39]

About 4k...

can be done. If your here to prove a D16y1 can make xxx amount of power then go for it.

But with that budget jump to a b16a and be happy.

To start off, get the usual bolt on. Intake/headers/exhaust + ecu and tune.

[B147ch]

cool..

I/H/E are already done..

VAFC II vtec controller installed and tuned at 83kW ATW..

where to go from here..?

[barefootbonzai]

With $4k - do a B16 Conversion and you'll be spanking All motor D-series setups all day long.

As fatboyz said, not unless you feel that you have something to prove like guys some guys on this forum, working the D-series is a waste of money.
