What the hell? You just contradicted your self. You just said that 5 is either std crx manual or std crx auto. Std is DX. You don't need a program you tell you this. Even in my helms it says its a DX.

Hows about you answer my question?

Does the engine look like this?


Or this?


To answer your question. You have to find a host that you can upload too. Then copy the url to here and use the code to display the pic.

 

okay...first i didnt contradict myself... what i posted came from a site from which the guy said he copied the information from a helms... i dont know how reliable it is or if he made any typos..and i told reason to give me the vin so i can check it and get a more accurate answer... 2. yes it is a hf... you can go to google and type in Vin decode and then just enter in your vin and it will tell you its a hf...for example ..www.autobaza.pl... go there and type your vin and it will tell you ..you have a hf as will others... so you can listen to ultimx dumba$$ or to me..a qualified mechanic or owns and runs an import shop..and races professionally... anyways good luck reason anymore questions feel free to ask me

 

It looks like the bottom pic. Is that the carb. on top? Damn I got an old dusty a$$ engine. I want to thank you 2 for helping me out. So we are saying its and HF?

 

Curtisy of Reason himself.
Reason, you got a DX DPFI or Dual point fuel injection.

 

Sweet, whats the difference between DPFI and MPFI? what is better?

 

omg you guys, the easiest way to tell the difference between an hf and anything else is that the hf has only 12 valves!!!!!!!! and the rest all have 16, so if it says you have a 16valve motor it is not an hf.

 

8 vs 16 valves is another.

dpfi has 2 injectors and is carbed. mpfi has 4 injectors and isn't carbed. Both have advantages and disadvantages. There are other reasons besides the 2.

 

actualy a dpfi is not carbed, considering that there is no carburator in the throttle body. it is called a tbi or throttle body injection, yes it kind of works as a carb in theory but it is different. and i thought the hf had 12 valves? or is it just 8?

 

seems similar to my mikuni carbs... but okay....

 

Why does the Si's intake go out of tis way to grab air from one of the hottest spots in the engine bay?
I took that stupid thing off so it sucks from behind the right headlight, with that a new O2 sensor at the same time (should've done them seperate to see what did it) I felt a small gain.
