Pictures of a 90-92 TBI Setup
 

I was hoping someone might be able to post (or link me to a web page) that has pictures of a 90-92 Honda TBI setup. My research tells me they come on a 1.5 or 1.6L... either of which is fine (anyone know the physical size differences?).

I would also like to see the TBI removed so I can get a look at it's flange and fuel fittings.

My goal is to find a fairly common 1.5-2.4L (around 1.8-2.0L preferred but I think the one mentioned here will work) TBI for a custom project.

Google searches for things like "throttle body injection" or "tbi" aren't helping. Can't even find any on eBay.

Thanks.

Honda didn't use TBI setup, dual-point is what it is called.

Good info. I'm searching on that now.

Any helpful links with pictures would be appreciated.

That is great. Probably would never show up in a search engine considering he spelt it "duel".

Reading through it now!

just look at all of them.

Actually.. wasn't very helpful at all. :( No pictures of the DPFI itself.

Re: Pictures of a 90-92 TBI Setup
 

Can you tell me which motor numbers the DPFI came on? Sorry, I'm not a Honda guy.

Re: Pictures of a 90-92 TBI Setup
 

why do you need pics of the DPFI setup??? you wont change anything on it to boost. you are limited to the bare minimum amount of boost, maybe 5-6psi safely w/ an FMU, unless you do the MPFI swap which is HIGHLY suggested. ;)

DPFI came on d15b1 and d15b2, maybe others, but im not too sure, those i know for a fact.

Let me clarify. By saying "I'm not a Honda guy" I meant that I don't own a Honda. I don't have this outside to look at.

I am looking at possibly using a DPFI setup on another motor which is currently in a carburated 1.8L British vehicle which is NA right now and probably will be for the next few years since the motor is original and stock at about 105k miles and 25+ years of age. Obviously this will require a standalone EMS (which is fine as another vehicle I have already has one and I don't mind another). I will be making a custom IM to mount this DPFI onto.

I would consider using just a normal throttle body setup (which I am considerably more familiar with), but I like the idea of a pair of injectors already mounted/sealed rather than having to fabricate an entire 4 port fuel rail (at least at first).

So the first thing I am looking for is pictures of a DPFI and it's hookups. Then I'll look into buying one. I'm hoping I can get one fairly inexpensively considering nearly everyone is ditching them for MPFI and probably has it just laying around in their garage.

Anyone know the injector sizes offhand on the stock DPFI by any chance?

Side note, even though it won't be going turbo right now, I have heard this was a very knowledgable Honda resource which is why I'm here (and not in the FI forum asking this).

Re: Pictures of a 90-92 TBI Setup
 

well, you first need to understand that the DPFI setup runs one injectors until the ecu reads load, only then does the secondary injector pulse. it sounds like a huge pain in the ass to me. and british cars dont excite me at all, so i dont feel like helping anymore, BLAH, buy a honda.

Re: Pictures of a 90-92 TBI Setup
 

lol, thanks for the help.

I do understand that they are not equal sized injectors and that one is the primary. It's essentially a smart carb.

I feel bad for you that you're not at all interested in making a British car a little homo.

haha, no offense, i just worked all day in the ------- heat and dont feel like thinking anymore about the outdated DPFI setup, unless its gonna help a honda brother.
