That's mad.Quote:

But i think my engine is a gen2 jap spec B16A
Around 150hp peak is exactly where i'd like to be.
Did you have a dyno sheet by any chance?
How were the mid range gains?
Do you know how much of an increase the port and polish provided?
Do you mind sharing how much it cost labour wise? (pm if you like)
This is the only bit i'm "umming and arring" about.
Thanks :thumbsup:
Sorry i don't have a dyno sheet here. its gonna get re-tuned soon as i had to change the ecu so i will post it up when it gets done.
the power gain was all throught the rev range.
I can't determine what gain was had by the port and polish but i think it to be a mandatory mod with big cams! there would be no point in trying to get a gain from an intake manifold upgrade if it is not continued throught the head!
I have buit my car by going backwards throught the engine.
exhaust-extractors-port/polish-cams- and next will be the intake.
my theory behind it is to get the maximum amount of power from the air that is already in the engine!
And it also helps you determine the shortcomings of the engine/drivetrain to point to the next mod rather than throwing parts at the car!
The price for all of this was about the $4000 mark. thats cams, springs retainers, port polish, adjustable cam gears, thinnner head gasket, fuel injectors and tuning. I think I covered it all.
Mate, thanks for the info.
I think you've pretty much convinced me now not to bother with aftermarket cams.
Thats alot of money for something that cams/valve train and tuning alone will make more power than a STD B16a cyl head will flow around 250hp STD please Toda correct this if I am wrong,B16a engines respond very well to BC3+ or Toda-A cams,to make use of a ported head you would need alot more compression than a STD B16a bottomend has.Quote:

I'm thinking even a larger throttle body & intake manifold may be overkill without a more agressive cam and higher compression.
Be good to hear from Toda or another reputable workshop with their thoughts & experience though.
All said and done I'm still 50/50 about the install.... so i've listed the parts for sale.
The B20Vtec in the BYP EG ran an UNPORTED cyl head it only had the combustion chambers reshaped using a CNC program that was developed here in Sydney that engine made over 150kw and yes it had a multi angle valve job.
I think a setup like this would be what your after
Std head multi angle valve job
Toda or similar valve springs
Toda Spec-A or BC 3+ Cams
Toda Headers good 2.25 or 2.5" exhaust
STD intake manifold fitted with ITR or upto 65mm TB
custom length CAI to suit your package
ECU Tuned with Hondata/Ectune/Neptune/Crome not that E-Manage crap you have or some for a piggy back junk.
That setup will make VERY nice power as a daily and return very good fuel consumption once tuned correctly.
Just a quick question for th op
where did you get your 4.9FD gear from, how much was it to get it installed,
i'm assuming it made a big difference in driving?
Also whats it like highway driving at say 100-110km/h in 5th gear?
Is it just revving off it face or?
the mfactory gear calculator is a pretty good resource to check what rpm/speed you'll be at in a certain gear with different gear ratio setups and final drives
