best way to build d series for more boost
well i will be boosting soon and plan to run 8-10 psi for right now, and down the road want to buy another d16 block and build it for boost. Ive heard rods, pistons, and a bore over is the best way to do this. Is this true, if it is what good brand should i get for rods and pistons? thx

HEY Iam on the same road ur in I going to boost my stock d16z6 motor with arp head studs and 450 injectors, msd I will like to run around 8 to 11 psi with a good tune .Then I wanna get a spare block so that I can put rods and piston and run around 15 to 20 psi
TUNING IS THE KEY

Re: best way to build d series for more boost (civicboy18974)
i recomend
sleeves,pistons,rods,balanced,rotated,blue printed
port and polish head for high flow (to push greater air flow)
also low compression for high psi applications!

Re: (exospeedAMcrx)
thats a nice block
the reason i recomend sleeves is because boost is ADDICTING!
your goals are ever changing with a boosted application and if you have a block that can take 500+ whp it allows you to change your application accordingly rather than to have to go into the down pipe it takes to sleeve a motor/block/pistons/rods/machining ect

Re: best way to build d series for more boost (rota92)
It's a sohc. IF you want to do a "built" set-up... Just go B-Series. You'll spend the same amount of money on parts.
Your stock single will hold 10psi fine, granted it's tuned properly.
If you stick with the sohc for whatever reason... Vitara pistons,and some tuner toys rods with stock sleeves will handle more power than you'll need for the street.

Re: best way to build d series for more boost (rota92)
well granted you have to understand some people may build a block for the street and change their setup and go with a track setup
its just good to know one side to the other stock verse sleeved.
and to say thats alot of money for a d series not really money cant be a object and if it is moding cars isnt for you, because everything is expendsive done right. and if it isnt expendsive you arent doing it right.
too many people cheap out when it comes to turboing a car and why cheao out when your motor is only as relieable as the parts you use in your motor.
and head work doersnt hurt anything more CFM flow will help your overall performance.
and i too agree if you want to build something go with B SERIES

You'll spend the same amount on parts, but you'll also have to spend the $2500-3000 for the swap. You could save that money for something better. Since when was two cams needed to make good power? It's just added rotating mass.

exatcly you can make a 400 whp d series for about the price of a gsr swap. hmm 400 whp vs.180whp

stop spreading misinformation. it is NOT a must have. no detonation+20 psi=how my car has ran for 1.5 years. nearly every day. i never turn the boost down, and i have factory sleeves. a local buddy is doing the same thing. lots of fuel, pull timing, and have fun. i dyno'd at 300.08 whp before i put the newest cam in (stock head/cam a6 then)

We still have to beat it into the newbs heads though that a swap is not the only option.

Re: (stockb18c)
psi doesnt equal power, you need to first understand you can run 2000psi if you arent making more than 150whp, your motor will fail at a given power associated to a psi level of a given turbo. 10psi on a holset would probably blow a stock motor where 10psi on a t25 is just a taste of boost

this is correct, in some respects. its depends on the amount of air the engine can move through it (including through the turbosetup), and how efficient the turbo is at that PSI level/amount of air movement.
10 psi with one turbo is the same as 10 psi on another, theoretically, but the air temperatures will be different, and the flow through the turbo could be drastically different (especially through the hotside)
10 psi, properly tuned, on a bigger holset, would do GREAT on a d16...but untuned, would blow to smithereens.

Re: (redzcstandardhatch)
if you have a t25 and a gt40 both at 20psi (lets say the t25 can hold it untill redline) the same exact amount of air is entering the cylinder, psi is psi, it doesnt matter what turbo it comes from. HOWEVER when it exists the the engine is where you get the difference between the capabilites of the turbo. Does that make sense? You could have a 42r compressor on a t25 turbine and it would only make 250whp at max psi becuase the exhaust housing plays such a crucial roll in making power in the upper rpm range and in and in high boost scenarios. In the example i gave the turbo would pretty much choke the engine to death.

Re: (redzcstandardhatch)
psi on one turbo is not psi on another turbo, different turbos flow different amounts of air. Hence a holset flows a much larger amount of air than a t25 will, or a gt40 vs a t25 for that matter, thats why you have efficiency ratings on turbos as well as a max air flow for each one, the amount of air that it can move is what makes power. A larger volume of air in the cylinder is what the ultimate goal is hence a turbo that flows more air will create more power at a given psi granted the motor can both flow the air and take the power
