7AFE swapped into corolla 1998

[Xulfiqar]

Well its not that cold thank God BTW How much time it takes to start the car in such weather?

I have had the chance to be in such an area. This is the sorry a** story.

Heat up key with mini butane flame and use it to thaw out the outer door lock (it was frozen)

Install battery

fire up welding torch to warm up the sump with cardboard over the icy ground (car block heater was plugged in overnight though)

Start engine - it takes 20 seconds of glow time and 10 to 15 seconds of crank time to start a healthy IDI diesel in such weather. The block heater helps by reducing this time to 10 seconds. Still the damn engine oil is like glue unless you use full synthetic 0 viscosity

scrape the ice from the windshield with nearly dead frozen fingers

drive off - with wobbly tires (tires are frozen with flat spots) tires become round after driving for 3 kms.

leave car running in parking lot while buying breakfast at a petrol station.

the fuel blends in such places are specially formulated for such areas.

Hmm that will be very hard to do everyday :p. I dont think i can survive such cold now. When i use to be large (120KG+ - 5-8") I never use to feel any cold even in -7 Temp or Muree i was in single jacket and slept in single blanket lol people were freezing but as I lost weight I can no longer take even cold weather of ISB around -0c at night.

Do we have some thing like pre heated engines in diesel where you dont have to give it the glow time? I remember my friends prado had 2 large batteries i guess he never used glow time hmm.

[Vaqas1]

Thanx Vaqas for such a detailed reply. I got a 4AFE that I bought for Rs 70k from bilal gunj and I was lucky to get a good one. It was almost like new as seen from the tappet cover, and yes the wiring was uncut and the electrician used the same wiring but the mahaan electrician insisted that he will use the old fuse box and part of the wiring. May be it was easy for him. The engine number also says 4A-xxxxx but the intake manifold or whatever it is looks like that of a 5A, I am sort of confused. The engine sounds great but misfires a bit during idling. It would drop rpm & vibrate awfully on CNG in the morning, but I got it tuned up and the guy made the IAC valve work. Now it does not drop rpm like it did before. The first plug turned out brownish/greyish white and the mech said its doing great and he did not bother to chk the other 3. Now all of my friends tell me that its an automatic----now enjoy..............
Everybody has liked the sound and acceleration of the engine but the fuel consumption is really bothering me.

I have also experienced the same CNG effect in RWP/ISB and Lahore. I visited RWP in Nov and filled up from Jehlum which took me 150 kms.
I don't have the chk engine light or diagnosis box.
I believe all the sensors are working (well...how many are there???)

thanx again buddy...

Why you bought an Auto old engine if you are looking for fuel economy?

There are few main things that should be connected like the ECU Should have switched power to +b and Live Battery wire to Batt.

STA (Starter Signal) should be connected to ECU.

Water Temp, Air Temp, Map, TPS, O2, these are the ones should be connected.

there are cylinder block heaters that are connected to A/C power - its fit in place of a welch plug or a dedicated port like MB diesels, you connect it to AC power and leave it overnight, it keeps the coolant temps near to 25 degrees celcius, the heater is about 500W though.

even with that you are supposed to use the glow plugs to heat the combustion chamber for the engine to start reliably.

and btw toyota LC prados/hilux use twin batteries in diesel editions, it was done to raise cranking amps without using one giant battery that would have never fit in the engine room anyway.

rules of engagement when dealing with EFI swaps.

rule 1 - the ECU needs ALL WIRES TO BE CONNECTED CORRECTLY
rule 2 - read rule 1

if you try short cuts or go cheap - the car will short circuit your wallet to PSO/Shell/Caltex etc.

[Vaqas1]

Cleaned the Engine area.

I need to do some thing to these headers hmm chrome I guess.. Couldn't find heat wrap in Islamabad.

[shazo]

sir g i can help u with these headers but m in lahore

[Vaqas1]

sir g i can help u with these headers but m in lahore

Sir Jee tell me how can you help me in LHR? I mean what to do with them :).

I like the idea of heat wrap but cant find em here :s.

[shazo]

sir g heat wrap will cost a lil, here in lahore i did chrome job on my headers for just rs 1k and looking great, but it took 1 week to complete such job.

[Vaqas1]

1 Weekkkkkkk Hmm that is a lot of time i was thinking if this can be done in hours...

[shazo]

not possible in hours i also wish that but final outcome was great. so sabar ka phal metha hota hai rest if u have some spare headers then took ur current one off n send it to me via courier, as soon as they complete ill send back to u thats what i can do for u

[DANY_KHANN]

Vaqas can you send the headers to Lahore i may be able to get it warped for you i really don't like the idea of getting them chromed.

[sinner__]

hey hello vaqas bhai ! i want to ask which generation 7AFE is this ? is this old or new ? the manifold with it is its orignal one or did u changed it ?

[Vaqas1]

Vaqas can you send the headers to Lahore i may be able to get it warped for you i really don't like the idea of getting them chromed.

Hmm Yaar Dont have any spare headers........ I will see what I can do i am also thinking of getting the original headers with cover..

[Vaqas1]

hey hello vaqas bhai ! i want to ask which generation 7AFE is this ? is this old or new ? the manifold with it is its orignal one or did u changed it ?

This is the old one. The newer one is Distributer less I guess and also got less HP than this.

Manifold this engine had was the one in the pic below but it was cut before the bracket so I asked him to find me the same Manifold and not original. This is 421 he kept saying sports wala :p.

Original tht came with engine is on right.

[Xulfiqar]

why dont you buy the original shield for it or get it made, I could get these made in Karachi for cheap, and then even punch some louvres into it. Powder coat it black or silver

[Vaqas1]

Back after a long time..

Installed Iridium Plugs.

Got the A/C Fixed the stupid electrition of pak like every car this car's a/c system is also hot wired :s and once its hot wired its very hard to get it back to normal...

Can some one help me in finding how to wire the a/c low pressure switch?

The original a/c system was in bad shape i had to change the compressor/evaporator/and condensor.

Old Evaporator.

This evaporator was soo clean we didnt even wash it just like brand new.

[sadiaali]

Wow nice efforts.

[NAQ300]

Excellent work done. A very informative forum. I am glad that every thing is done to its orginal shape (as much as possible).

Definitely will need your help and expertise if I plan for a swap. Best of luck.

[aliusman420]

what total cost did you incur so far for the engine and cng?
