So i have to say thanks for the feed back, keep it coming!

I have a couple more questions about the NA feed back.

1. Am i going to gain a couple horsies by raising th cr, just with a different head gasket.
2. Say i changed the cr would i have to change it when i go to emissions?
3. Could someone explain the 2.0 part cause i really want a 2.0 GSR where would i start?
4. Also would it be pointless to get apr-rod bolts now, and if i got them how do they help the car perform?
:thinking:

All the info u give helps, thanks!

 

1. Maybe a little bit. But you'll have to take the head off to install it and it's not really worth the trouble unless you happen to be taking the head off anyway.
2. You're not going to pass emissions without a cat. Put one on, and you will most likely pass.
3. To get more displacement you have to either replace the crank and rods with ones that will give you a longer stroke (this is not advisable for several reasons but for now just take for granted that it's bad) or you have to widen the bore of the cylinders and run wider pistons. You cannot simply bore out the stock cylinder sleeves, you need to replace them with new ones first which can handle larger bores.
4. Again, this is a lot of work to take apart the motor just to install some bolts. This is the type of thing that you do with the motor out anyway.

Since it sounds like you plan on going with a larger displacement motor at some point down the line, the best thing to do for now is to work on the top end. Without removing the head, you can replace the cams. For a B18C1 I recommend the skunk2 Stage 2 grind. To go with the cams you will need at the very least upgraded valve springs and retainers. To tune them in you will need adjustable cam gears. You already have the V-AFC (which as have already told you in a previous thread isn't doing anything for you until you tune it) so combined with cam gears that will give you all the adjustability you need for a dyno session.

Step 1: if you ever want to pass emissions get a high flow cat
Step 2: replace the cams with skunk2 Stage 2; upgrade valve springs and retainers; install cam gears to help with tuning
Step 3: take car to dyno to dial in V-AFC and cam gears

 

Yeah im not stupid i know i wont pass emissions with no cat on. But thanks for the reply fatbooty!So are u saying if i got it bored i would have to deffinenty have to get sleeves that are proper for the applacation(of course),and also get a new crank and rods that will handle the the new displacment,correct?
I know the only reason i got the vtc afc was to look kool for the women and for tunning later on.But would it help my car if i got it tuned now? lets say i do get my car tunned and i have no internals should i aleast get cam gears for more tunning , or should i wait till upgraded cams, then tune?And as for the skunk 2 cams i heard that i wont pass emissions with them

The steps are pretty much correct though on what i need to do,thanks.

 

Thanks for the clarification Snoopy...are you certain though the GSR intake is not the same as the ITR exhaust? I always thought they were.

 

The stock crank and rods will work fine when you bore out a motor. You replace the crank and rods if you want to make the stroke longer.

If you want to get cam gears now and put the car on a dyno to tune both the cam gears and the AFC you will see some gains but nothing drastic.

With a cat, pretty much anything you do while normally aspirated will pass a sniffer test just fine assuming of course that your air/fuel ratios are dialed in properly. That includes changing the cams.

 

I know im still learning here so I have another question. Could you explain what happens if I were to replace the stock crank and rods and make the stroke longer.I kind of have a general idea but, sorry im still a newbie. :wiggle:

 

Stroke is defined as the distance the piston travels up and down inside the cylinder. If you switch to a stroker crank and rods, the piston moves further. That gets you more displacement. You don't really want to do this because it will make your car less eager to rev. The old B20A5 motor in the 3rd generation Prelude went this route to achieve its 2.0 liter displacement while using the same 81 mm bore as all of the other B-series motors and generally speaking people aren't such big fans of that motor. Its stroke is 95 mm as compared to 87.2 mm of the B18C for example. The B20B and B20Z which are the CR-V motors got their bigger displacement by running a wider 84 mm bore instead of the stock 81 mm bore. They have the same crank and rods as the LS motors (B18A1 and B18B1) but more displacement because of the wider bore.

 

adding stroke will lower how high u can rev your engine don't do it if u want as much power it's better to bore it out

 

yeah i would like to rev pretty high. Something that impresses me you know. thanks guys.

 

im pretty sure the cams themselves are not interchangeable between the intake and exhaust sides.
