I'm thinking about getting a header for my eg si. Right now i only have an intake and exhaust. So the question is it worth the money to get one. Some guys is selling some no name one "rocketz 4-2-1" for cheap. So i don't know if i should get it. The price is good, but i don't know might just be a waste of my money. Would i notice big gains or not? Also does anyone have any experience with this brand of header??
either save for a B series swap or a turbo manifold for you current engine. I saw save for a trubo manifold if you plan on going turbo... becuase D series are limited to all motor activity... I think
okay,thanks. I guess i will just save the money. I really want to turbo the d series that i have, but it has a high milelage. The egine still runs strong, but burns oil on vtec engagment at higher rpms. compression is about 160 across and leakdown is about 5%. How much do you think it would cost me for a custom turbo setup. I don't really want high boost, just about 4-5 psi.
A friend of mine builds custom turbos using DSM turbo with all custom everything else. Uhmm w/o intercooler 700, w/intercooler 800 + cost for Intercooler.
yep, don't spend money on a header if you're going turbo or swapping. if your motor has high mileage, pull it out, get some stronger rods (i would never turbo a d16 on those pencil thin rods), get some forged pistons if you feel like it, new rings, new rod / main bearings, arp rod bolts and headstuds, and a good cylinder hone. also a good 3 angle valve sealing job and some serious love (replace water pump / timing belt / oil pump / all seals / gaskets / etc) will help it run like new. then boost away. you'll get real tired of 4psi real quick. build it right the first time. also look into an lsd, as a turbo ff car should definately want one. basically plan on spending more than you think, if you want to do it right. a nicely done turbo project can actually be pretty expensive. or you could do it dirt cheap like they do on www.homemadeturbo.com . read through their project section, so you can see what happens when you cheap out. but, i do agree with them in that custom kits are definately the way to go. some of them are done nicely, some are built for under $1000 and don't last 2 weeks. you'll need to upgrade your clutch, fuel injectors, and get some good engine managment - at very least a vafc, or ... hondata . i'd plan on spending anywhere from $2000 to $4000 depending on how you can find deals, and how half assed you do it. i have to say it again, cheap, fast, reliable: pick two. and don't rule out an NA B18 swap just yet. i changed my mind between the 2 at least 43 times, before finally going with the b18c1. it's not in yet, but i've very happy with the decision.
seriously though, what's the performance diff between an SI header and an ITR, besides that one is midrange and the other is high range. I mean what's the flow difference
