I have read many posts in advanced tuning about spending several £K on internal engine mods.... :dance: If only I had the money :(

 

But the engine is coming out for Tub replacment and I'm interested in a list in order of priority/cost of things to replace.

 

My current plan goes like this

 

 

Tub's....Ouch !

PCV's.....got

O2 sensors....got

fix me dead knock sensor.... hoping just a dead loom

Remove AGR.... yet to learn

Remove AIV.... yet to learn

 

The list could be endless but with budjet in mind what else is a good idea.

 

I'm thinking about heat tape wrapping the exhuast manafold...

 

A. I'm sure it makes stuff all difference ?

B. does it protect other components from heat ?

 

What would YOU do ?

 

 

 

 

 

 

And P.S. what is it with the new smilies :ttiwwop:

I don't know but someone had to use them

might have a look at this post - http://www.300zx.co.uk/forums/showthread.php?t=42035

Vijay you are a wealth of info, now I have been reading the advanced tuning forum but must have missed that gem....... I think I'm going blind :eek:

I've asked Eric (Lymon) this exact question before and I've just dug up the mail :)

 

When I pull a plenum I usually bypass/remove all waterhoses and gaskets under

the plenum/throttlebodies and bypass the EGR by capping off the holes

under the plenum and the pipes coming from the EGR.

I also replace the "hard to reach" hoses (water/fuel) with high quality

silicon

hoses instead of rubber and it's also a good time to replace the fueldamper

and regulator and all fuelhoses/clamps and give the injector connectors

and throttlebodies a good clean.

I usually also remove the AAC valve, take it apart and clean that as much

as possible.

 

 

With the engine out, check all freezeplugs for corrosion/rust and replace

if needed.

Usually the rubber engine mounts don't survive the removal, so you might

want to have new ones ready for when the engine needs to be reinstalled.

I usually replace the steeringrack rubbers, since you have good access to

these with the engine out.

Check the engine/oilpan for signs of oil leaks and replace/fix (with new

gaskets, seals, etc.).

 

Also very important: check the oilpan for dents before installation !

It very often happens that the oilpan gets dented (when the engine sits on

the floor or during removal), which often causes oilpump pickup problems

and this leads to low or NO oilpressure.

If you do have to remove the oilpan for gasket replacement or dent

removal, also clean the oilpump pickup filter/mesh.

 

Other possible things to replace/check with engine out:

-clutch/throwout bearing

-check flywheel for cracks and teeth on the gear ring

-installation of downpipes and/or replacement of O2 sensors

-replacement of gearbox mounts

Good time to do a 60k service too! While you're at it, replace the cam oil seals and rear main seal. Also, if you do pull the plenum, reseal the rocker cover gaskets....

If my name was John Dixon I would throw the V6 lump in the bin and fit an all-aluminium V8 instead.... lol ;) :D :D
