225++whp

Plans:
Send block (with all bottem end components) to NRG (good guys) for bore/hone/hottank/assembly
Bore .20 over
Use eagle rods and je pistons (recomended for good budget, yet not cheap build)
Arp studs
OEM headgasket
OEM bearings and whatever rings
INline4 bottom end gasket kit
turbo XS (or other brand) mbc
Hondata s200 w/ boost
Dsm 450s with resitor box
Tuning

1. Was wondering what Size pistons to use with the .20 over stock bore??

2. What bearings/gaskets/rings need for bottom end assmebly? All oem Good?

3. Anyone used thepartsbin.com, and if its reall OEM stuff, and if so, how did u Like it and whats service like

All responses are greatly appriacited..

use .20 oversized pistons

all OEM bearings and seals and rings will be fine, so long as you use rings that are properly sized for your pistons

Still need to know what stock piston size is so i can go .20 over
anyone?

ueatdooki

you might be able to get stock ls pistons machined to your block if your sending it in, there cheaper than getting forged pistons and there boost friendly.

kommon_sense

do you mean ls rods? Cause he won't be able to use the pistons.

95turbohatch

NO ls parts.
I am getting forged pistons and eagle rods..
i just need to know the stock piston size??
CAN ANYONE HELP ME ON THAT..

hey bro if you ever find out let me know too....REALLY INTRESTED IN BUILDING MY STOCK d16z6............want about 200-225 horse power on the greddy kit.....

I Gotta Question

guys if your lookin for 200-225 on your blocks you dont need to build them um, just go with a block gaurd and some good tuning, maybe a 2mm head gasket, other than that you can hit 200 225 hp on like 10 psi good luck though.

LS pistons = 81mm

SOHC = 75mm

That's a HUGE OVERBORE to fit B series pistons in a SOHC!

But for the questions:

1) Check with the piston manufacturer that you're going with. Most can do customs sizes, or have popular sizes in stock.

2) OEM always.

3) Never used it, sorry.

Sure man anytime, btw good luck with the buildup and I hope you meet and surpass that 225hp goal

95turbohatch

NO!

20 over is in thousands of an inch.
0.020 over is actually 75.5mm

Common overbore sizes on stock sleeves are 0.010 and 0.020 over, or 0.25 or 0.5mm

I will be running 77mm pistons on my sleeved rs block, and I m selling a sleeve 75.5mm GE Sleeved ZC

95turbohatch

So the piston size i will need with the .20 stock overbore
will be 75.50??
is that correct?

95turbohatch

have you heard/read this thread...

https://honda-tech.com/zerothread?id=267641

It's a guy selling machined b16a rods with toyota pistons (forged)...

He's run pretty high boost with nothing but those and a thicker headgasket....

95turbohatch

Thanx alot, Good thread..
Really intersting and might go in that direction..

Why are you rebuilding your motor? D series motors arent as weak as everyone makes them out to be, 225-250 whp is safe on a stock motor. The sleeves are exactly the same as a b series motor, the only weak point is the rods. If i were you, I wouldn't do a rebuild unless the motor is already toast unless you want 300+ whp. Tuning is the key to keeping a motor healthy, not building it like a brick shithouse.

I am prob going to go with this piston / rod assembly i read the thread alot of positive responses about turbopanda and his work
