Project_SOHC_EX

I want to make a 300hp SOHC-VTEC engine. I wanna know some possible suggestions as to how to go about doing so. I need to know everything which pistons, which rods, sleeving the block(if necessary), injectors, spark plugs etc, etc. But most of all which products to use through which company and why? I wanna do it right so that my end result is what I intended.

I would definitely suggest re-sleeving. Golden Eagle was my choice. Step it up to a bigger bore to get more displacement. Choose a piston (Endyn, Je, Arias etc.) Go with Eagle rods because they are nicely priced and work well. Get a nice valve train (valve springs+retainers) to hold the revs, and a cam to make the high end power.....

hey VTC, you building a motor??
what's ur setup?

also, this is a newbie question
i know what resleeve is now, but what is re-bore?? or bore to a bigger size??

explain plz

Yes, your correct but if you rebore your engine, you can only step it up about .1 because of the space, well lack of space, between the pistons.

VTC_CiViC

The new setup will consist of:

D16Z6 block and head
OEM headgasket
77mm bore w/ GE sleeves
Crower rods
JE 9:1 pistons
Blueprinted and balanced bottom end
Extensive headwork (PnP, bowel work etc..)
Not sure what cam/spring combo yet
SFP Mani
T3/T04E

Looking for no less than 400whp

COOOOLLL

what is Blueprinted and balanced bottom end??

also, i still don't get what 77mm bore is!!??

i am not sure if u can answer this, what exactly do they do when they resleeve it??
cut out the stock sleeves then put a better quality one in??

hehe, maybe i sound stupid, but i really don't know

Bore breaks down like this. For instance B series motors. In a b18 block, the stock bore (diameter of piston) is 81mm. When people say "20 over" It means that part of the cylinder walls are bored out to accept a larger diamet piston in the case of "20 over" it would be 81.5mm. Now what I did was had golden eagle resleeve my motor with their sleeves and bore it out from 81mm to 84.5mm. Which will take my over all displacement from 1.8 to about 2.0. You cant bore any more that 0.5mm on the stock cylinder wall because they will weaken too much.

Balanced and blueprinted means that they Balance your rods, pistons, crank, flywheel...etc. to work in sync in high rpm use. Hondas are very well balanced from the factory but when you get into using alot of aftermarket parts balancing is a good thing to do.

OH Great, great info

i think i totally got it now !!

so re bore it = change 1.8 L to 2.0 L = so u will need a bigger piston?? does the piston must have a exact fit to the cylinder wall?? or some gap??

i think i got it, but can u explain a bit on the benefits of having a bigger displacment = bigger piston??

I talked to one of the local performance shops around me (IMPO) and they told me the max I could bore out my engine (D16Z6) was 10 over. Is that true or not?

whats the biggest bore u can go with when the motor is sleeved?

jdblack1

here comes about $8k . I started my list like that and then

First step for any force induction for honda is a standalone system!

VTC_CiViC

According to GE, for N/A 78mm, boost 77mm.

what about with the B series?

boostinb18

so what exactly do they do when they resleeve??? do they put a new sleeve inside the cylinder then bore that one out??? do the remove the stock sleeve?? and what material do they use?? and if your only going .5mm bigger could you just use the same pistons as stock just with fatter rings??? or how can you get the right size pistons???
sorry for the newb questions but this is stuff i need to know for my LS/VTEC/turbo build up!
thanks!!

so let's say u bore it out to 77 mm, how many L does this mean?
2.0? 2.2?? 1.8??

Ltech

They are going to cut out the old sleeves and press the new sleeves in. The material is iron. If you change the bore you need to change the pistons.
