mpfi conversion in Florida?

Hey, is there anyone in FL (preferably So. FL) that can help me convert my STD to mpfi?? Thanks!:biggrin:

:boink: that made no sense but i get what you mean...haha and tyour too far from me

Too far? Nah.... I could be there in...hmmm with 70hp...in 3 weeks! I'll have to push it up the rocky mtns! hence the need for multi port!!:bloated:

Were exactly are you located in Florida? I am about 30min. south of Tampa.

I'm in Boynton Beach, probably about 3-3.5 away from Tampa. I'll be there a few times this summer though. My cuz lives there.

Let me know when you head that way... I got to Tampa/St. Pete every weekend with some friends of mine (races).

Don't STD hatches have a restrictor plate in the intake which limits them to 70 HP? If I remember correctly, you can remove it to get 92 HP...still not MPFI, but better.

Will do VelocityCivic, I'll let you know the next time I go up there. Hey, where do you get parts down here? Looking for someplace lose to cut on shipping costs...

Oh and what is this about the restrictor plate? Is it hard to remove it? Will it really bump up the hp bit?? Anyone out there ever tried this?

Yeah, I have done it. It works a little. Better than it in place though. Take off the 4 philips screws that are holding your DPI plate on. Once that is off, you will see a little brass plate covering most of the hole that the air goes into. Remove that with the one philips screw that is holding it in and your done. Test drive it after your done to see if YOU notice a differance. If you reallt want, you can also remove that little screen dome lookin thing over that little flap in the DPI "box".

Great, I will have to do that this weekend when I have a little time. Any drawbacks to this?

None that I have found. My friend did it to his 91 4 door a while ago (before he sold it) and he said that it slowed him down. :confused:

is it only on STD's?

STD's and DX's I think. Any Civic with the dual point setup.

I know there are so many sides to this...but you think doing this and also adding a generic aftermarket intake would give me a little more power as well? Geez, I'd be happy with 3 hp!!

It will be better than stock! :smile:

so its in the lx?

Yes.

the restrictor plate wont give you a very big gain, but when removed, u wil feel a better throttle response, depending on who you ask

Correct me if i'm wrong...but I thought the only difference between the STD engine and the DX / LX engine was the restrictor plate. Yes, they all have DPFI - but isn't the plate the only reason the STD is 70 HP instead of 92?
Hell, if its not, I'm gunna gut my DPFI and get some power! :smile:

I have never heard of that. I wouldnt think so.

Wish that were true! It would solve half my probs right there!

just took mine off no more then 20 minutes ago, it responds better but i dont think there is a gain in hp, unless its hamster power. but hey its worth it

Just took mine off a few minutes ago too. Feels better, but it's probably my mind playing tricks on me. Damn, wish I had a dyno.

hey tanked, your not too far behind me on the engine mod. all i have is the restrictorplate removed and a short ram intake :bigthumb:

How about Daytona Beach.

Hell yeah, power to DPFI!!

actually, I was hoping to do an MPFI swap too :smile:

Hey Turb Civic, I'm about 2.5 hours from Daytona. My folks live in Palm Coast. Know any good places up there that can install springs and shocks on my STD??

there are more differnces in the STD and DX. for one, the STD is a differnt block, meaning that is probably has slighlty different pistons. And also, in addition to the resitrictor plate, the throttle body itself is different. on the DX, thre is the throttle plate and then under that, there is another restrictor plate. on the DX, it opens as a normal throttle plate, but on the STD it only opens about halfway, further restricting airflow.

Also, with the STD, it uses a PM9 ECU and the DX uses a PM5, which is geared more towards the 92hp engine instead of the STD's 70.

swap ecu
remove restrictor plate
remove throttle body restrictor plate
= homemade DX

How much is a PM5 ECU going for?

Hey Stali08, how much gain are you getting from the Short Ram?

Speaking of which, do the eBay no-name brand intakes any good?

Honda sure went to great lengths to cripple the poor STD...geez.

Too true....too true.... but at 185,000 and still runnin....they did a pretty good job putting it together....:cool:

its not too much of a gain maybe like 5hp thats about it, if that. Um the company I got mine from they just custom made the pipe, and put on a K&N Intake. When I go to ask about an exhaust system I wanna ask them how much it would be for a custom CAI.

yes ... they do. Noticed more of a difference with this on than I did with my exhaust and high flow cat

i just did it to my STD HB as soon as i read it..no difference..in fact i think mine does run slower...:frown: fuck..

does a 91 hb si have MPFI on it? Sorry I'm not very motor keen

uh not trying to sound like a ass but um, just look under the hood.

Yeah, the SI's all have MPFI.

All Honda fuel injection is MPFI except the 88-91 STD, DX, and LX's.

I have a 1991 Civic Wagon, with the dpfi d15 engine, I think it is rated at 92 hp... will mine still have the restrictor plates? and if a remove them, would I expect a hp gain? or even any throttle response? This car has absolutely not throttle respoense at all, I mash the gas and it revs to about 3-4, but in my CRX, if i even lightly touch the gas it goes that high i have the ECU from a 1988 CRX Si, would this ecu work on the dpfi or would i have to swap over the entire intake setup?

Just removed mine tonight. I guess there is a little gain (I think I was getting my hopes up too high) But nothing that will snap your neck. Can't hurt it right? Maybe I'll jam one of those little tornado turbine things they sell in the "as seen in TV" store in there and gain another 20-30hp...:rolleyes: people actually bought those things!!!:loser:

so are u saying if i take off the copper box in my dx thats alrdy whips preety well for only 70 hp then i will get 92 and my car would fuckin fly?

I wouldn't say fly...but if you close your eyes and think real hard...you might think you feel 2-3 more horses...or maybe mice.... didn't hurt anything.... I don't know why it is there in the 1st place.... ??
