Ok so here is the plan, I'd like you to guys to give me your input/experience on the situation.

I've got a 2000 integra GSR that is in need of a rebuild (smokes like a chimney). I live in md and have emissions to deal with. Here is my plan, I want to put in type r pistons and cams. And replace the intake manifold with a skunk2 to get rid of the secondary butterflies. I'm pretty sure that type r engines have larger Injectors can somebody confirm this???
I was going to use a type r ecu to take care of deleting the secondaries.

Do you guys think I can do this successfully and have them plug into the ecu at emissions and not be able to tell the difference?

I need to know about the injector size being different. And if the type r ecu will work with the skunk2 intake manifold and not require any additional tuning and not have to worry about any check engine lights.

Passing emissions is very important in this so I need to make sure that it is definitely going to pass with this build.

Let me know what you guys think any input is appreciated thanks in advance for any help

 

56 views and no input??

 

All obd1 and obd2 B series injectors are 240cc

 

Here are the specs on my last build:
94 gsr w/.25 os usdm type r pistons, Endyn ported and milled head, type r cams, port matched S2 manifold, crx si-r air box , stock injectors and stock ecu. Compression was around 11.3/11.5 to 1. This setup passed California dyno smog test w/ flying colors. It also later put down 177 hp on a dyna pack using a knock off ITR header and tuned on neptune. Hope this helps

 

Yeah that helps but what I need to know is if i can just use a OBD2 2000 ITR USDM Ecu and have it run the engine without any further tuning or modification with the fuel/timing system. The way Emissions work in MD for OBD2 cars is they plug into the diagnostic port for the ecu and read it and I want to make sure that if I use that ECU that it will read correctly. I Also want to know that using the ECU with a setup thats built close to itr specs will work without any CEL's or other problems. You said you had your setup tuned and if I keep my car obd2 which I have to for emissions purposes I have no way of tuning it. thanks for the help and any other input you can give!

 

If you build the motor to itr specs(kinda like mine was) wouldn't it make sense that a stock itr ecu would run it??

 

Yeah mine was tuned, but it ran good on the gsr ecu, but because I was running a S2 manifold and not the stock gsr manifold it's midrange was a little weak...you'll be fine with a stock itr ecu.

 

Yeah it makes sense thats why I put it out there as an option of what I can do. I just want people's input and experience with doing something similar. Like I said, I need the car to pass emissions without any hassle or headache. I want to make sure that it's going to be as simple as plugging in a USDM 2000 ITR ECU. and Having No CEL's and have a smooth running car.

 

Free bump!

 

I doubt your emissions test is strict as mine is in cailfornia, you'll be just fine.

 

i'm not worried about it failing because of a sniffer test i'm afraid that when they plug into the diagnostic port they will know that its no the right ecu because of the vin number of the car. they use the Vin number to know what type of car it is before they plug it in. I guess so the computer knows what to look for and how to scan the computer for codes etc... I just want to be sure that i wont have any cel's. that the Type R ecu isnt going to be looking for any sensors that I wont have hooked up etc...

I'm probably not going to get any headwork done besides maybe springs and type r cams. I want to use a skunk2 manifold to get rid of the secondaries. and i'm going to use type r pistons to bump the compression. Can i just use the gsr throttle body on it?

 

integra and 96-00 ecu's don't display vin #s.

 

GSR throttle body is fine, thats what i ran.

 

thanks for the help guys.. now i've got to start buying some parts lol... are type r and gsr retainers the same? would all I need to upgrade is the springs? would you recommend me getting stock honda type r pistons or aftermarket pistons? would you say that getting used pistons is a good or bad idea? would getting something that would bump the compression slightly higher then 11.1, somewhere closer to 12:1 require any major tuning or would something as simple as an adjustable fuel pressure regulator and a little timing adjustment be all that is needed? or would i need to use some type of fuel/timing control with that much compression?

 

00 itr ecu has the immobilizer. So doesnt the 01. You need to find a 97 or 98.

 

Are yo* talking abo*t it having a *hipped key? and having the green key light that flashes on the ga*ge *l*ster? My gsr is a 2000 and has a *hipped key and the green key flashing. Won't the type r e** work on that or does it have to be disabled?

 

It will be disabled becasue the three immobilizer devices do not match.

 

Will that cause problems with the car not wanting to run? I would imagine if the ecu is programmed to look for the chipped key and it wasn't the correct one that the car wouldnt start.. Can anyone verify if this will be a problem or not?

 

If you can get the vin for the itr ecu you are going to use, you can take your car to an acura dealer and have the immobilizer reprogrammed to read your stock key. They usually charge an hour labor.

 

I don't understand why you don't just use your stock ecu and have it tuned on chrome. this is the best mod you can get hp per dollar and then you don't have to worry about all this. a tune should be required for any changes that big and it's probably cheaper than a new ecu.

definately DON'T buy used pistons. just get some new ones. oem honda will work fine for what you're doing here.

the difference between 11:1 and 12:1 compression is HUGE too and will require a tune. My ls vtec with stock gsr cams put down ~175whp and I think it was mostly just due to the ~12:1 compression the motor was running.

if you want more mid range you can always get a p30 intake manifold too, would likely only cost you a few hp on the top end with a big gain in the mid range

 

^ He must use an obd2 ecu so that the obd2 scan tool can connect with his vehicle..

It should run fine. They all run the same sensors, so as long as there aren't any differences then it'll run.
