dude you aint got a fucking clue what you are talking about, VTEC is nothing lie a turbo at all, it lets the engine draw more air in, turbo FORCES ALOT more air into the engine, and the trannny causes the engine to burn oil because the line loses presure and the tranny slips. well how does a 5 speed tranny slip, autos slip and fluid pressure in them to shift and stuff, but oin a 5 speed the clutch slips is the only tihng thats gonna slip, unless you chew every tooth off of a certain gear or something. and no the B21 shouldnt be 210HP, the B18 is not, the C5 is higher than 100/liter, the C1 is a bit lower, the B16 can be equall, lower or higher depending on country it came from. the K20 in the base is 160 and in the type S is 200, you cant say an engine should have thois msany HP because 100/liter is the standard, its not. also the way the engine leans hasnt a fucking thing to do with the synchro wearing you damn stooge. the synchro doesnt spin all gears at the same time, it gets the gear and the input shaft (I think, not sure what parts it gets moving exactly) spinning at the same speed before they engage as you shift. and no engine in any honda has been "BUILT FOR TURBO", if itr was built for turbo it would come with a turbo, honda foesnt boost their cars, I doubt they ever wil form the looks of it.

ban this clown, he just gave a years worth of dumb ass information.

type s prelude h22 not type s rsx k20 i know that and the 87 prelude is an an auto didnt you read the original message or did you rip in to me instead of trying to help anyone "ass clown" but what do i know i only rebuilt my own engine and now drive a 97 lude and working a 240sx to silvia s14 conversion with a sr20det engine, have you ever even changed your own oil, ya thanks. as for the k20 2.0L = 200hp so shouldnt a b21 2.1L = 210hp but you did get me on the synchro 'whops' and i said vtec is a cheep version on turbo not vtec is turbo. the way the engine sits does matter because the engine and the tranny sit on rockers and shift in a pair if the block sits in the wrong direction it causes stress on the tranny and they kill one another also h22 are to much power for a civic body design and cause the chassy to warp so if you change the engine also swap the tranny. and i like that ding on the front of your integra nice work, if you talk trash about me again ill kick your dick in the dirt and smack your mouth loose, ok tuffy, so hop along done done because your done. - fuckin' mikeymackinon

HAHA mikey youre an idiot. I didnt say it was a K20 in the prelude, it was a reference to your "this engine should be 210HP because itís a 2.1 liter" bullshit you wrote. the prelude is an H22, 2.2 liter, obviously its not a K20 since those are 2.0 engines. and you were the one talking about synchros and the JDM ITR tranny w/ LSD. I didnt know ITRís came with an automatic, sorry! oh wait I still donít think they did. and even if an automatic tranny slips, how the hell does that cause the engine to burn oil???

and what the hell are you talking about here?


"im still pissed and that was 4yrs ago the b21 has a low compression ratio because of its designe to be turboed i have been told it puts of 250hp when turboed and N/A (ZEX Kit)"

youve ben told it puts out 250 HP when turboed and normally aspirated. I REALLY hope you mean 250 when boosted and 250 when built NA or I really feel sorry for you. and N02 is sorta considered FI in a sense, so its not technically NA right there, you inject N02 which becomes heated and releases/FORCES more air to be in the cylinder than would normally be in there without it. and if it is built up NA and has the same power as it does when TC'd something is wrong, turbocharged should yield you way more power than NA, and especially across the whole board, maybe you have the same peak number but thats not all that counts, I donít even think youd have that though.


another thing, the fan pulls air through the radiator, and thats MUCH MUCH MUCH better than blowing it across the block. and nobody cares that it isnt blowing at the engine when the cars off(although it does somewhat since the air doesnt get through the radiator, then through the fan and just STOP dead right there. when the cars off, it isnt going to get hotter so theres no point in having fans blowing all over it. but when the cars sitting idling, what do you think would be better, water INSIDE the engine pulling heat from the engine and being circulated through to the radiator, being cooled and going back to rob more heat from the engine and then come dissipate it to the radiator which gets cooled by the fan and this goes around in a big circle continuously, or the hot water just keep getting hotter and a fan blowing at the block on the outside trying to cool the cylinder walls and everything INSIDE the engine where itís the hottest. when driving sure you donít need a fan, but idling you DEFINITELY need a fan.

and you say this,

"cooling system itís a bad designe it has 2 fans one is an eletrice and cools the rad not the block when the car is off but what it should have also doen is ran the water pump" ,

like you think that all the other cars have water pumps that keep pumping the water through after youve turned off the car and walked away, which, well, cant happen since its driven off the engine and if the engines not running, the pumps not spinning. maybe there is some cars out there with electric water pumps but I havent ever heard that before, not tp say that means they arent out there but A LOT less than mechanical ones for damn sure.

"1 deally is fule e-conime so 93 integra gsr 1.8 (vtec)"

first what the hell does 1 deally is fule e-conime mean???

2nd the 92-93 GSR's had a B17A (1.7 liter), 94 and up are the B18C1's

I love this one

"ok so in a nut shell b21 is good if you turbo it and install an intercooler if not check your oil and coolant every week"

so if I turbo my car, as long as I put an intercooler on it I donít have to check on things at all, but if I donít boost it I need to check my oil and water every week? only thing you could have meant different is maybe if you donít intercool it then check your water and oil every week, but you know the intercooler cools your air, which gores right into the engine, mixes with fuel, gets ignited, gets HOT and then still gets your turbo DAMN hot anyways, so either way the turbos gonna heat your oil and or water, depending on what turbo you got and how its bearings are cooled.

"2001 prelude the type s 2.2L= 223hp vtec thats type s not the s model 2.2L = 200hp vtec "

both of those have the same 200HP 2.2 liter engine. the type SH has 200 HP and the base has 200HP.


I could basically prove you wrong on EVERY SINGLE statement you made in your WHOLE ENTIRE post.
