as long as you are staying out of boost there is no noticable decrease in MPG. All a turbo does is add an a**load of air to the mix. Obviously you add an a**load of fuel to compensate hence a decrease in MPG. Stay out of boost when its not needed and you will be as happy as you are now at the pumps.

 

I know this might sound like a stupid question, but I have to ask. I have a 02 honda civic coupe. I want to put another engine with turbo into it. I was wondering what would be the best engine for the car and what turbo would work the best. I was wondering if twin turbos are worth it or I should just stick to one and just get a bigger one. The car is basically stock, just has some racing springs with new exhaust. Any help would be appreciated.

 

Honestly, twin turbos would be a little overkill in your vehicle. they are normally put on vehicles that make an insane amount of boost, but run 2 small turbos to cut down on lag. or they are for V series engines (v-6, v-8 and so on) with 2 cylinder banks and 2 exhaust manifolds, so that you can obtain boost from both cyinder banks and you lose less exhaust energy.

Somebody else can answer whats the best engine for boost and what the best turbo. My thoughts would be a low compression B18 with the GSR or ITR tranny to handle the power. a nice t3/t4 trim would be good for street boost and you could upgrade from there.
But any engine coud be boosted, but i would be careful with the D17's i don't hear too many great things about them, but they shoudn't have the oiling problems of the D16Y7 (which i've seen handle boost quite well)

 

for boost you want low compression... nitrous is better with high compression

 

of the y7? I know the y8 has an aluminum pan, but the y7 has a steel pan that the drain line can be welded too, so i don't see why the y7 would have more trouble than the any other engine; matter of fact alot of y8 users swap on the y7 pan so it can be welded if i remember correctly.

 

thank you for the time you put into that and i know im turbo charging my civic now. i know for sure that i am picking up a t3t4 turbo too.

 

i like the write up///im new to the site and everything and am getting a 04 honda civic in about a month or so. i want to put some performance parts in my car and this really helped. im looking for as much advice and suggestion as possible and im really gonna take this into consideration. if you have any other advice or suggestion that you could personally give me, just message me please. id really appreciate it and would love the help.

 

still reading the posts, very interesting and explicative. but couldn't resists:

LOL

 

The key difference between a turbocharger and a supercharger is its power supply. Something has to supply the power to run the air compressor. In a supercharger, there is a belt that connects directly to the engine. It gets its power the same way that the water pump or alternator does. A turbocharger, on the other hand, gets its power from the exhaust stream. The exhaust runs through a turbine, which in turn spins the compressor.

 

way to just re-say wat the OP said, ur and idiot stop trying to act like you kno everything
