I have almost completed my first major DIY job - changed head and block in my P11 (SR20, M6 CVT)
Can the pros give me some heads up with what checks I need to make before I try to start engine up. Any thing a rookie may have overlooked that could prove disastrous...
Really appreciate any advice that is given. |

I've never seen one in T&T... I'm going to buy my own.
Cylinder head bolts definately need a torque wrench...
Search "How things work"... Google... etc. |
You just bought an old engine and installed it?... What warranty did you get?
If you "open" it, either buy (and use) a NEW torque wrench... or *get a NEW mechanic* (who has one.)
BTW... is this really bad?... Don't know specs for SR20...
but FYI Mitsu engines use "torque to yield" con-rod and cylinder head bolts.
Both are ONE USE ONLY  ... Replace with new Mitsu bolts on every rebuild/gasket change... or buy ARP bolts/studs. IMHO check to see if your SR20 is similar.

ohh, if u just changed the head&block and didnt "build" the head and block
and all u really doing is mounting it back into the engine bay, on to the tranny and bolting back the normal bolt on's, the torque wrench may not be necessary for that |

apparently its just a head and block swap, he didnt assemble the parts in head and block
in that case the torque wrench really isnt necessary |

^^^^ thats it... thanks
just never spent so many hours working on my car so I guess it seemed "major" to me.
So just fill up with oil and tumble..? (belts, seals and water pump changed)
everything else (tranny, alternator, power steering pump, distributor, a/c) was from original engine.
What about timing? seeing i removed the distributor and have no reference bolt markings. I dont have a timing gun. |

| The distributor should be on a sliding device for adjustment. Easy was to get timing right id to slacken the 2 bolts for the dist. and adjust, on every incremental movement listen to the throttle response by stepping on the acc pedal. The best response should be where u lock the dist in place. If you are not to clear on what i just told you best bet would be to see a pro. |
