LMAO Hao
Didn't take ya long to start thinking about tinkering with your daily
Pre built fast cars are just not as fun when ya love to tinker like me buddy...
You pay the cash and buy the fast car! Now what do you do, clean it on weekends hahah

YEah that one's still in the wood works, 220kwatw starting to not be enuf now its awaiting parts to jump it to 270-280kwatw :)
The daily could do with a poke i think, just to give it a lively kick :)
Luke if your free maybe you can help me install the turbo kit if i get a greddy kit to bolt on.
We can do another honda build thread, its not an issue cos i got 2 cars this time
lol you want my turbo kit hal :) i took it off the civic already :)
lets get the ev cracking time to haltech and E85 its arse :)
lol had some problems with parts from the US. Once they are here e85 all the way.
Ry - can't afford a good turbo kit for the D, it has to be a dirt cheap on in the D series theme.
SO far the D series has had all its mods as hand me downs LOL.
Only the EVO gets new parts
Its a T4.......
hey guys just thought i'd join this convo.
im running my stock d16y4 130kw for about 2years, t2560r, 2,5'' full exhayst at 7psi.
ems stinger ecu, 255lph fuel pump , 440cc injectors, fuel reg along with all the little bits you need to make it run.
its running great but i am planing to update the head, the single cam just not cutting it anymore.
my question is, is there any point in rebuilding the head. or do i just go the B series motor?
also what D series twin cam head bolts up to a D series sohc head??
None do. Your only chance would be to drop in a shaft for some more power, otherwise build the block. or get oversized exhaust valves for a SOHC vtec setup as SOHC vtec only increases intake valve lift duration an not exhaust (which is why SOHC vtec sucks).
Do you drive it hard? I'm surprised the y4 block is holding up with. 130kw atw without snapping a rod.
^ Have you got any proven results to share in regards to needing oversized exhaust valves for a Sohc Vtec turbo ?
No, I'm just offering a suggestion.
It's common knowledge that SOHC VTEC sucks compared to DOHC VTEC (for modifying and power output etc) and one of the factors is this - that the SOHC VTEC only affects intake valves, whereas the DOHC affects both.
This is why engine builds like Adrian at TODA recommend using standard VTEC B-series valves in head builds (most of the time). It only makes logical sense that oversizing SOHC VTEC valves would help it to breathe better in VTEC.
Mate im totally aware of the operational principle on both Sohc & Dohc Vtec... i can also appreciate the reasoning in what you are saying. But honestly even Bisimoto's 700whp 9sec sohc ... has not adopted that theory. If you are going to the effort to run oversize valves - IMO - you do BOTH exhaust and intake.

It is correct you cannot use a Dohc Head on your Sohc block. If you are chasing more power, you need to understand that you are reaching the limit you can achieve on your current setup and standard engine. IMO you only have two options and both involve removing the engine from your car.
A) Abandon your setup - sell everything and put towards a B / K Conversion
B) Rebuild your D16 with forged internals (Pistons / Rods & general freshen' up) and a Sohc Vtec head aka Mini-me (aftermarket cam, valve train, Pnp, head studs)
