from what I know the orange is better, and coolant has an any rust chemical inside it. i hear 40coolant/60water is best for summer and opposite for winter, but 50/50 should be just fine too. I wouldnt really worry about the rust too much though, just surface rust, not like your block is going to rust through and break on you.

off gmcanada.ca - 2860lbs with 50/50 distribution off honda.com - 2855lbs for the s2000 looks like direct competition to the s2000. dont hear anyone complaining about that being too heavy

just in case you guys are interested in that cargo ship motor http://www.bath.ac.uk/~ccsshb/12cyl/

how come no1 had said anything about nissan's FJ20's? awsome NA or turbo motor. Designed originally for rally and other racing, but later put into street cars. it was used on S12 silvias and i thik DR30 skylines. these motors are BULLETPROOF. Aftermarket support is "decent", the heads are able to breathe very well and ITB's can be used and it can be revved very high. This will definetly be an "original" idea lots of info on www.fj20.com . This engine is kind of rare, but I dont think it should be too expensive compared to sr20's or rb's.

how much power do you think toyota pickups put ou with their 4 cylinders? probably about the same, and yota pickups aent light vehicles whatsoever. i had just done a head gasket on a 4 cyl jeep but im sure these motors are very similar to the 6 cyl variants. anyways when I took the valves out to do the seals, 3 of the 8 springs were broken. My boss had said that it was a common problem on these jeeps. the replacement springs were only 3 bucks a piece, doesnt say much for their quality.

it may have shorted out the cpu as well... i guess you could try starting it and if it doesnt then bargain for a better deal

engine should be brought to operating temperture before doing a compression test so that the piston rings expand and the gaps are minimized

how bout windsor 351 heads outta 96 f250 into a 95 s/c mustang? just that my buddy with the stang has a 351 engine sitting around. If its worth it maybe we could pop the 351 heads on there if they flow any better

very nice, very clean I like the CAI routing

that videos halarious

i say put the 5L in the z and the 3L turbo in the stang lots of wiring work but it sure would be interesting just a question, why are you even considering the swap? is the original motor weak/blown?

hes still working on it?? I'd love to see some pics of the progress........ if there is any

wow this thread is from almost 3 years ago I'm assuming the swap never happened, but I would definetly love to see a rotory in a z. "May as well throw in my .02. Horsepower is horspower but I would never use a Zcar body with such a low amount of mass in the engine compartment. These car's need to transfer and a Wankel doesn't move its mass like a SBC, or a VG30 or a L28. Use the 13B on a short wheel base car that ways nothing. I like a 82 Toyota Starlet. But be carfull they come around after 8.0's." about this quote, rx7's have a pretty long wheelbase as well. in fact the longer wheelbase would make it a true midship car which would probably greatly improve handling and balance

i dont think it'd be that expensive sure it'd cost more than a chain or belt but it would never need changing. with some belt kits costing a 100bux or more a one time investment in a couple of gears shouldnt be that bad and because oil can flow to it it can get constant lubrication and the bearings would probably never go bad either how much friction loss do you think there would be with gears as compared to chains/belts? would there be any wear at all with proper bearing lubricaton and splash lubrication on the mating gears (if needed)

thanks for the great responses. much better understanding now

sounds great, what kins of muffler it that? is it dual pipes the whole way or do the join then separate again later on?

makes sense but still doesnt really explin why everyday streetbikes wold use chains that require maintenance while choppers which are used once a month or never at all, and are probably stored well would use maintenance free belts but i guess thats a totally different issue anyways

also why do all those chopper guys on tv use belts for their drive wheels? most street bikes use chains

so i guess my first opinion of belt for race and chain for race is wrong eh. kinda the opposite way i guess race engines would rather take the dependability oof a chain, even if there is slight friction loss. Does anyone know for a fact that chains have more friction then belts? it makes sense to me as each link must move against each other, even with a roller chain

true, also they must be heavy compared to belt/chain system and might rob some power ps. i just read my first post and i accidently said belts are noisy, i meant chains. i edited that out

very interesting gear drive setup, never seen something like that for ohc engines hows the noise? any special lubrication needed? friction loss? why dont more manufacturers use such setups? it would completely eliminate piston to valve damage for interference motors

just wondering, based on opinions, which you thought would be better for a street motor and a race motor? had a discussion with another mechanic and thought I'd get more opinions. im not going to even consider gears since this could only be done on ohv engines with the cam close to the crank my opinion is belt for racing and chain for street Ive read that belts use less friction, therefore are better for hp, but chains are obviously more reliable even though belts are getting pretty good now too. chains are also noisy but i guess it can be solved with proper insulation. I am confused why every honda I've seen uses belts but the s2000 (the most performance oriented) uses a chain

no, sorri thanks for putting me in my place

wondering if its ever been done. dont know the exact figures but i know its a pretty good motor with impressive numbers should be quite easy to find, exept that its a fwd engine would be interesting to swap in a high revving dohc domestic motor

94 caprice with a 350? would this be an impala ss? i thought those were the only ones that came with 350's, and I think they have corvette drivetrains. those are really nice by the way, there was one by where i used to live with a set of 20's... very nice
