I just thought I'd bring this to yer attention. Let's say you are running a carbied V8, due to fuel inconsistencies in any carby system with near zero management, I can guarantee you will decompose more catalytic convertors than a vat of acid. Catalytic convertors get dissolved by unburnt fuel in the exhaust, this is why we have EGO, EGR and a gazillion other allegedly "redundant" bits hanging off our unleaded engines nowadays. The ECU regulates the spark and fuel delivery so there is bugger all unburnt fuel left in the exhaust so it doesn't kill the cat. Even if you do get past your first emissions test, after 5000 kays I can guarantee you won't get anywhere near close to legal emissions, and if you want to fork out $400 or so to replace your cats every 5000 kays be my guest... On top of that, please, and I mean "please" (in a quaint non-confrontational way) don't tell us how much horsepower you are going to get, or how much horsepower some other dudes "similar" engine has. It's not constructive in anyway and only creates un-needed debate. Now to add fuel to the fire of that debate, just so that you know where I stand on all of this. Comparing a racing engine and a street-able engine is *chalk-and-cheese*. They might have the same bore and stroke, and "similar" ports, but they are very different in more ways than u'd imagine. For starters, you think a racing engine has a catalytic convertor strapped to it? Do you know how much hp these things can knock off of a big capacity engine - up to 40 hp - if not more. And on top of that, the carbies are totally different tuned, the cams are set up for only high end performance, and on top of that - to deal with all this, their diffs are locked up tighter than a CPA's ass, and their gearboxes take more steroids than chinese swimmers. Sure they might get 400+hp - but that's at far more revs than a normal street engine ever runs at, and it's at a sacrifice to low end torque/power curve. I'm not going to say how I personally feel about putting a ford into a toyota, but whatever floats your boat On top of that. I'm not a moderator, and no one is being forced to listen about what I think a board should be conducted like, but don't dis other engines...sure there are pieces of shit engines out there, but just because you had/worked on one that blew to smithereens doesn't mean every engine is like that. I've had my 3S-GE run fine for 30,000+ kays with worn rings and oil blowing out of the exhaust and leaking from the cam cover - (this is due to the previous owner being a dickwad), and all I did was top the oil up every now and then (until I got sick of having less guts from blowing oil instead of exhaust gases and I had the cash to fix the engine) and the worst damage was extremely minor scuffing on the number 2 piston. The bores were still very visibly cross-hatch patterned, not overly worn, and the lip on the bores was tolerable. The crank was fine, but due to the fact the engine had 200,000+ kays on it, the bigend bearings were worn to shit. So there are people with stories of engines holding together good despite poor treatment on my and the previous owners part, and there are people who have stories of engines blowing up left right and centre. And on top of that, don't expect people at a TOYOTA mods forum to treat you like a hero if you say a Toyota 7M-GTE is a hunk of unreliable garbage... Sorry, I'm getting way off track. Happy engine converting! [Updated on: Mon, 03 February 2003 12:41] [Report message to a moderator]
