holly crap, how long did it take you to get all this maticulus #ing down, I thought I had a lot of time on my hands, your:first: at time consuming proj.

I found most of that elsewheres, I just put it all together in one thread.

[itsanep3]

Nice! Any idea where the knock sensor is located?

[SinisterCivicSi]

awsome work doug! thank you so much!!

[talonXracer]

Nice! Any idea where the knock sensor is located?

#15 in the first pic, just behind the intake manifold support.

[b.r.i.a.n.]

i've seen this on k20a.org. this deserves a sticky.

[talonXracer]

Gonna bump this for the newbies to read..............

[MasterPD85]

very clean engine and very well done.



worst oil filter chaning ever. '96 camry is bliss compared to this lol

[ep3egg]

This thread delivers, ephatch please sticky. :msmile:
