![]() ![]() You're better off getting pistons and cams and doing a rebuild or going turbo Some people have pinging issues others don't. Several things need changed out from the fsde. Although I think this rumor just came from the honda community so that they could sell their ragged out civics with swaps that had "70k" miles on them Lots of 240 owners that do sr20 swaps don't last long unless they rebuild them. Now if this is true what you have to look at is people not giving 2 s**** about maintenance and runing the s*** out of them because at 60k miles their motor is replaced. Supposedly in japan the motors are replaced every 100k kilometers because after that they pollute more in theory. Not nearly the emissions stuff we have gave it the extra power, along with a few other things better intake tune etc) MP3 got 140 hp from a better tune and vtcs deleteįsdet ( what you have with a turbo bolted on) 170 hpįsze ( higher compression better cams. It has been my experience that forum search tools are useless- this forum, included.įsde ( what you have) 130 hp. What should I expect to pay of a JDM FS-ZE engine? Any suggestions for who I should buy from?Īny suggestions appreciated. 15-20 HP, I'd probably be happy as a clam at high tide with the resulting 185-190 HP, especially if I thought I'd have a reliable engine- and that would be far less trouble than installing a turbo on anything, wouldn't it?ĭoes the FS-ZE engine have (dare I hope?) forged pistons and/or rods? I am guessing that the pistons in the JDM motor are higher-compression- can it be turbo'ed without going "boom?" Actually, if the JDM produces 170HP, and (if I understand correctly) a cat-back and CAI add approx. If not, what is necessary to get it to pass? Is the JDM 170HP a drop-in replacement for the 2.0 in my P5? I mean, drop in and plug up and go, with no mods to make it pass US emission tests? (Atlanta test emissions yearly, no pass means no re-registration.) So if the two motors make the same horsepower, they CAN'T be "internally identical," unless the turbo is just there for show and isn't actually DOING anything. How could the Mazdaspeed engine be "internally identical to the regular FS-DE, except with a turbocharger installed onto it," yet make the same horsepower? To my way of thinking, "internally identical" means the same pistons with the same compression ratio, same cams, etc- that all the things that make more or less horsepower are the same. This means that the Mazdaspeed Proteg's engine is internally identical to the regular FS-DE, except with a turbocharger installed onto it. Mazdaspeed decided to turbocharge the regular FS-DE, as the FS-DET in 2003 for the Mazdaspeed Proteg and it generated 170 hp (127 kW) and 160 lbfft (217 Nm), the same hp rating as the naturally aspirated JDM FS-ZE but with a sharper torque curve. Japan received a higher-performance 170 hp version, known as the FS-ZE. In 1998 the engine evolved into the FS-DE by undergoing several changes, most notably a distributorless ignition as well as the move from hydraulic lifters to solid shim-on-bucket lifters. The 2.0 L (1991 cc) FS has an 83 mm bore and 92 mm stroke and produces 130 hp and (97 kW) and 135 lbfft (183 Nm) in its most common variant up to 170 hp in the Japanese Domestic Market. I just read, on Wikipedia, the following (I have a Protege5, btw) It also appears that high-performance engine are falling out of the trees in Japan, ready to be scooped up like so many cherry blossoms and shipped to the US. What is this all about?įrom what I can tell, or rumor I have heard, is that Japan required a car's engine to be replaced after a certain number of miles. LOTS of importers, all happy to make a buck, but not a one that I could find with any really useful info. Seems like there is NO solid info on this subject on the internet. ![]()
