Difference between 89 da9 & 90 da9

[IZY-10]

hey guys just wondering i have always been under the inpresion that the 89 had the same power as the 90 da9. However i was looking on redbook.com and it says that
89 has 103kw@6300rpm
90 has 96kw@600rpm
The torque level however is the same. Is this possible even though they have the same motor or do u think they have a different CPU?

got it the wrong way round.
90-91 had 96kw 92-93 had 103kw
had slight upgrades and breathed a lil better.. thats about it

nah i actually dont here is da web site to prove it

I dont think redbook is going to be 100% accurate.

Many other sources will prove that.

its a mistake.. as freek said 89-91 is obd 0 series 1 LS..
92-93 obd 1 series 2 LS upgrade face and compression is bumped up a notch and a few minor tweaks to put out 10 more hp

you can believe redbook if you like :zip:

does that mean the 89-92 ones can adjust something to get an extra 10hp from sumwhere?

[FR33K]

you mean upgrading 89-91 for 92-93 "adjusments"
no
money better spent on aftermarket mods

its pretty simple....92-93 are OBD1, whereas the earlier models were ODB0...

would explain why kal thinks my 89 is faster than his 90 :p
i thought it was
89-91 DA9 96kw
92-93 DA9 103kw

It is.

it is what? quiker or more powerfull?

[krovikan]

I would say that neither car is really quicker.. with thoes kinda differences, it will come down to the better driver

[integrity]

redbook is dodgey ...
trust me the 91's are quicker and they seem to scream a little harder
my 91 was one lil beast for a 1.8litre

[INTEGGRA]

better driver be right too ! the diff in KW wouldnt be noticable from car to car anyway you would have to have the exact car with exact same replacement's and parts or compelely stock never touched never driven we are talking about 9KW from a a 15-17 year old car.

[integrity]

true ...

[string]

In my car, I previously had a 1990, 96kw version, then changed to an OBD1 103kw motor, and it certainly is/was faster. Stock everything on both, except the 90 motor base timing was set at 21.5degrees, and my current motor at 17.5 degrees.

Driver certainly plays a part, but in my case, that's a constant :D

The pants say it's faster :)

[INTEGGRA]

any idea what they put down at the wheels?

[FEL12X]

so is actually the ecu or the engine make the difference?

i also heard the 92-93 model ls can do vtec conversion easier beocs of the obd1 loom is already there so u dont have to touch the loom..just new ecu and engine then can be done...is that right?

[string]

It's a combination of both;

Yes you don't have to touch the loom for an OBD1 VTi-R conversion, however type-r's were only OBD2 IIRC. Most people when doing swaps like that do not leave them stock (its a waste otherwise) so therefore you can get a obd2-1 thing and then plug it into an obd1 computer and tune it that way. OBD1 ecu's are the tunable ones.

If you get a half-cut, it's not a problem anyway; It's not really that much of a task to pull out the whole loom out of one and put it in another (trust me, i've done it) compared to the whole engine swap itself.

As for power, allthough you'll have no use out of the number, as it doesn't really mean much, my OBD1 B18A1 put down 89.6kw, completely stock sans a bit of timing and intake only up to the box. That is slightly over-corrected (screwy intake probe) in dyno dynamics shootout mode. To aid the cause, I do have either a blown headgasket/cracked head causing chronic burning of coolant (though, on the day of the dyno, it wasn't as bad as it is today).

The end.
