Im buying a gsr swap, the ecu was tunned for turbo and it has bigger r/c injectors. it was fully rebuilt and never had the turbo on for more than a 1000 miles and the receipt says it was a 900 dollar tune,question is can i use the bigger injectors and that tunned ecu without a turbo when i put it in my 92 civic without any problems, i just dont want to damage the engine, i wont be putting a turbo kit on till like next year, can i just run na for a year or so with no problems thanks guys

 

with no turbo you will need smaller injectors...and you will need to retune....

 

hmmm. maybe i wont get it after all i dont want to ruin it and if i buy the swap ill be to broke to retune or change the ecu and buy new injectors ill just look for a cheaper stock gsr swap thanks

 

my buddy has a complete h2b setup for sale if your interested....

 

h22 with a b series transmission right? i would love an h22 i dont care about ps but i need to keep my a/c its hot as hell in texas....lol i think im going to do a simple swap b16a or somthing thanks though

 

one more question,about the ecu.....lol if i do get this swap, if the gsr head says p72-2 does that mean its obd-2 for sure, i came across a 99-00 civic si b16 ecu will that work for a b18c just wondering so i can actually drive the car lol

 

Is the engine stock internally and are you using the stock intake manifold?

If you don't want to get it tuned, you need a p72 ecu, especially if you're running the stock intake manifold.

I believe on most chipped ECUs, you can just cut the connection where the chip is soldered in and it returns it to stock, and you would also still have the chip for when you want to go turbo. This would only work for you if it's a p72 and not a p28 or something.

You can find a virgin obd1 p72 usually for around $100. If money is a big issue, I would sell the injectors and use the money to pick up the stock ecu and some stock injectors. If you can't afford these little things, don't do the swap, because money will be a bigger problem if you half *** something as critical as fuel and engine management and you ruin the engine.

Also, I'd be sketchy about buying an engine that has been turboed, unless I REALLY trusted the person I was buying it from. At the minimum get a compression test if the engine is still in a car. If it's out of the car already you can do a leakdown test.

 

The code on the head has nothing to do with what obd it's running.

i had an obd1 b16 head that was pr3-4 and an obd0 head that was pr3-3

Edit: BTW, it's "tuned" not tunned"

 

great advice money is an issue at the moment, i dont think im going to buy that swap since it had a turbo on it already it might have been dogged on,im just going to buy a b16a2 short block and get it rebuilt ,a few people are selling those locally here and then ill just buy buy a gsr head or something i and piece it all together dont want insane power something quicker than my d15b vtec just 160 or 170 to the engine and very reliable is good for me thanks for all the advice

 

For 160-170 engine hp I'd stick with the d-series fwiw.
