@Vaqas
You skipped my question. . .

[margallar]

I used these headers they are 4 2 1.

Condition as you can see they are bit rusted and pathan bolta hai sports wala hai :p.

These come without any cover so engine is clean these look rusty. Please suggest what can i do to get them cleaned. Buff these? Paint? or any other method?

The other headers in pic were in better condition but they were cut from joint so didnt use these.

you can give it to those shops that make wagon safeguards, maybe they can sand and chrome them, this facility is available at montogomery road lhr so it must be in islamabad, somewhere, i dunno much abt isloo

[Vaqas1]

From where you bought that engine in Rawalpindi?
Whats its price and for how much you sold the diesel engine?
Best of luck for the swap.

Engine by giving old 2c I bought it for 55k.

Mechanic 5k

Electrition 2k

Other things oils/exhaust work around 10k.

[sayyedain]

nice decision of swap. waiting for car running videos and more details

[Vaqas1]

Today i checked error codes and Engine is givng error code 12.

What can be an issue? no STA Signal?

[Xulfiqar]

error code 12 = no NE or G signal - engine is unable to calculate spark advance. It will be hogging fuel.

Yeah thats what i think. It gave me fuel avg of not more than 4 KMPL :P.

I am using this ECU.

Now i need to find out how to check NE or G Signal from distributor to ECU.

[theone326]

nice clean swap... 4Km/l :S disgusting

[Vaqas1]

Thx, Fuel avg inshaAllah It will be fixed the one

[DANY_KHANN]

^^^ Get it warped will give you nice look plus low heat in the bay.

[Vaqas1]

Dany not sure where to get wrap from Islamabad :s.

Xulfiqar bhai today I took the wiring out from inside the car and checked NE G Signals all 6 are properly connected. Than my mechanic thinks Map Sensor wiring is not proper so checked that it was also fine. So i was wondering why its giving code 12.

Finally I checked STA as the ecu was giving sta missing. The STA signal some how is missing from the wiring even though I opened the wiring loom and took out wires they all seem to be properly connected.

Anyways for testing i connected STA and Bingo car started engine was smooth no more black smoke did a test run and in runs like a beast keep spinning wheels even in 2nd gear..

Checked codes again this time no codes. Test run again this time Rev LImiter also kicked in (It was not working before) than check engine light (I connected small bulb to holder for check engine light as meter got no light) turned on.

Checked codes and it 52. 52 is Knock Sensor so i will install that too its missing from engine block though wire is there for it.

Now engine is running very smooth

[Xulfiqar]

I think you did an error in checking codes the first time, when checking codes, first read the codes, then reset the ECU, then read the codes again after letting the engine run for 10 minutes.

When your electrician must have installed the wiring, he must have cranked with no distributor connected, that would cause a 12 code to register - and stay there till you erase it. So next time follow the correct test sequence.

Good that you have a good running engine now.

the STA line should be originating from the fuse box where the starter relay is, its a black/white stripe usually in toyotas. In a diesel car the starter wiring is thin from the key because the diesel starter relay is the thick white chunky relay hanging from the shock tower. You are supposed to tap it from before the relay - there would be a test pin for STA though in the cars original wiring which you can use.

Actually when i was having code 12 i did reset ECU by dissconecting its plugs for few mins.

The Code 12 was coming in weird way.

After I connected back the ECU first code I got was for STA than 2nd was code 12 but than only 12 code keep repeating and STA will not come.

To get sta again you have to dissconect ECU than STA one comes back but only for once than disappears and code 12 remains.

It seems all set now If I dun rev hard and check code again no code comes.

Few things are left to be done.

Ecu Needs to go its proper place.

Circuit opening Relay needs to be added ASAP. ( Will find the relay in market first)

Original STA wire will be checked.

That's an interesting swap and the overall costs seems quite reasonable as well.

Good luck with your project.

[celica]

@Vaqas1,
Whats the total cost of the project and from whom you got this engine in Rawalpindi.

Asghar Khan his shop is in Ahata Mithu khan right next to a radiator shop of Mithi Khan ahata chowk. I like him because he is nice honest guy and will not try to cheat you.
Price of 5A or 7A is same in Pindi so Engine he was asking for 60 by giving my old engine I managed it for 55k in the end.

That included foundations of car, Power Steering Pipe and other small bits.

If you swap it from them than the cost will be low but i chose my mechanic so he does his work properly so the cost did go bit more than what these engine people take.

Total Cost in the end is close to 70K.

7AFE 1800cc its a nice powerful engine.
