Boring the cylinders

[gmcuajo]

I just want to install some OS 0.5mm OEM pistons (bore: 75.5mm) on my 01 civic. I already have the civic repair manual where they say the clearance between piston and cylinder wall... To install those bigger pistons I need a larger bore, how I can bore the cylinder for those pistons? I need micrometers to meassure and some other tools?

And do you think is well install those 75.5mm pistons, or is better the 75.25mm?

P.S.
When the part number says the piston come in a "set", it means a set of 4 pistons or a set of piston and the wrist pin? What price you think are those piston for a 01+ civic (repeat are OEM OS 0.5mm pistons)?

Here is a DIY of the D17 block I had found online if this helps any.

Q: Can I use my own block?
If you didn't have a major malfunction that cracked the block or sleeves you may still use your own motor.
You may have a mechanic take it out of your car or if you have the tools and garage rent an engine hoist and do it your self.

Q: Once I have the block what do I do?
A: Since my stock engine was running fine and I purchase the block I was able to safe money by take in it apart in my garage.
I bought an engine stand for $80.00 an the Honda service manual for $100.00
It was very educational and a lot of fun striping that block bare.
I could do no harm since it was already messed up.
(note) safe all the screws, bolts and extra parts you'll need them on the future.

Q:What parts do I need and were do I get them?
A: At the time there was no pistons or sleeves for this block so I hit the web and started calling manufacturers.
I found a place in Lake Worth Florida were they do research and design parts for well known manufacturers.
The place is call Race Engineering Tel: (561) 533- 5500 ask for Jonh if you call him, deffinately tell him I, Hector told you about them and he'll work you a discount also tell him about our 7thgencivic site.

Any way I took the bare block to him with a stock piston.
And they designed a full floating piston and had Wiseco build it.
(Full floating piston are pistons that use a losse connecting pin that attaches them to the rod as opposed to the pressure conecting rods from stock reducing friction,they are a bit noisy and rattle when the engine is cold)
At the time I went for a bigger size piston 76mm (stock 75.02mm)

Piston part # XT- 519P76 Wiseco 76mm 9:01 compression about $450.00
I check my compression at about 95 lbs after installing this pistons
(stock 135- 145 lbs)
Wiseco now makes 75mm pistons (stock size)

Tell them that you are turbocharging and they will recomend the right set of rings and gap clearence.
depending on how much HP and size of turbo you'll be using the type of rings will be suggested.
Heat will expand and contract this rings so gap and type of rings will make a difference if you are racing at the track of just if you just driving day to day

Definately talk to the ppl at Racing Eng. for your application
Sleeves part #DS-300-010 Darton flanged sleeve from a D16- 75mm
I had to bore this babes out to 76mm to fit my oversized pistons.
Skip this step if you are using 75mm pistons.
About $210 a set of 4

Rods CR- BR3740B Crower Billet Honda 1.7
$600.00
The good thing about Racing Engineering is that they will give you all the specs and measurements that you need for the machine shop.
This sure helps if you are not a car guru.


Q: And theeeen?
Take the block and parts to a machine shop and give them the specs that you'll get from Racing Eng. along with the Honda service manual
The block will have to be bored to fit the sleeves about 78mm and the cranck shaft line honed.
Also make sure the shop resurface the top of your block so is nice and flat.

Sleeves pressed in and bore out to fit the size piston you choose 75mm or 76mm and the bottom of sleeves noched to make room for the crower bigger rods to clear ( bigger rods will touch the bottom of the sleeves as they turn up and down


Q: Now that I have all done how do I put it all together?
A; I deffinately recomend getting a good shop to do the job.
Make sure they are proficient in Hondas and take with you the service manual and ask them to see it carefully and use all the torque recomendations.

I would also purchase a gasket kit and new cranck shaft bearings $160.00
Check the manual book to learn how to order your bearings they come in colors yellow brown green etc.There are numbers on the block and the camsaft as well as on the rods.
The bearings can be any combination of colors and almost unique to your block.VERY IMPORTANT!
I went OEM you may choose after market.

KMS Block Guard if you want one, $40.00 http://www.7thgencivic.com/forums/sh...ms+block+guard
The BG is an insurance agains cathastorphic failure on your internals.
It sort of keeps thing togerher.
It works great on racing cars one 1/4 of mile at the time, but on a daily driver can get the engine overheated on hot days
(there has being issues with Block Guard heating up the head because it obstructs the free flow of water to the head)
So I modifed the BG to flow more water by opening the holes on a side to side configuration as shown below

Follow up with a set of ARP heat studsARP headstuds
ARP part # 2084301 Honda D-16 HSK for 1.6 SHOC vtec application. 10 studs
NOTE: ARP makes two types Z&Y (OURS is Z) about a $100.00

why are you doing this? For the amount of money you're going to spend doing this, you could do something that is actually worth while. If you're doing it for power, you're not goingt to see a whole lot....why dont you boost or put low comp pistons in and then boost the shit out of it and actually make some power rather than wasting money on a few hp...

Preparing the block for turbocharging. It is on... Read well...
