Polished and Ported Head - 8/10/2007 11:06:26 AM    D17Punk   Posts: 151 Joined: 8/10/2007 Status: offline Quick question. I'm rather new to this stuff, but I just wanted to know if I am running a Nitrous system ( Nitrous Express) would it be worth it to get a ported head with new piston heads, valve springs, and cam (shaft and gear). I know D17 are bitches to mod but I wanted to get some feedback on this before I jump into anything that might be worthless. Thanks. Post #: 1

I know most heads are used for forced induction only so if I dont run a turbo on it, is it worth upgrading it? (in reply to D17Punk) Post #: 3

How big of a shot are you running? _____________________________ (in reply to D17Punk) Post #: 4

RE: Polished and Ported Head - 8/10/2007 1:19:01 PM    D17Punk   Posts: 151 Joined: 8/10/2007 Status: offline Just a 50 shot. What kind of bottom ends can I get to make it a little more sturdy. I have been told they are weak but I was too stupid to ask what mods I could do. (in reply to D17Punk) Post #: 5

The engine is probly good for like.. say 180whp. If you really wanna get the power going, get yourself a decent platform such as a D16z6 ( 92' - 95' civics) Or a D16y8 ( 96 - 00 EX civcs) Youll have a much better experiance. trust me. _____________________________ (in reply to D17Punk) Post #: 6

I know that i could do swaps and different stuff like you said an older style civic but I was just looking for other options around that. I really just want to build it for like 230-250 whp and 190-210 wtq something pretty fun to drive around without a turbo but i know either route of building the motor or turbo is pricy.

RE: Polished and Ported Head - 8/10/2007 7:44:19 PM    johnny Posts: 1906 Joined: 10/30/2006 Status: offline You could honestly pick up a 1.6 litre D series engine for like 500 or even less and put a turbo kit on it, and it would be able to handle 225 horsepower with a good tune on the stock bottom end. don't expect to see that much torque on a honda engine. Expect to see around 140-160. Atleast you can wind them out to 7k+ though. Lol. _____________________________ (in reply to D17Punk) Post #: 8
