Hi guys. Ive been over on the vxronline forum for that last year but a change in circumstances (having another baby and trying to buy a house) means I might need to sell my astra. I've wanted a 300zx ever since Gran Tourismo 1 came out on the playstation so here I am! Looking for advice on buying, pros and cons of n/a, twin turbo, v6 etc, So...hi :)

Right. So an induction kit/air filter, stainless exhaust with sports cat or cat back (not decat) and a remap should be a good start and reduce initial mod costs. What size is the standard exhaust? And how big can you go and expect gains (when do IOU loose back pressure, if that ever happens)?

depends what you want to gain and what your tastes are, standard pipes are (if i remember correctly) 2.5 inch pipes, most after markets are around the 3inch diameter, and will go on the standard cats if you get a cat back system. you will see more power gain from a standard exhaust, and a even bigger one if you remove the cats.

 

just be warned though, removing the cats can be a mine field, as most haven't been removed before, so the studs that hold them onto the turbo elbows tend to snap. some times your lucky though. you can also run the car down to a local garage and ask them to use some oxyacetylene on them and start them undoing with out risk of them snapping. (doesnt always work) if they do snap they will need to be drilled out and either re-tapped, or if you can rescue the threads, new studs put in.

Removed the precat from mine a few weeks ago and even after only 3 years of rust one of the studs sheared half way down. 20 years of rust I would imagine makes it impossible. fortunately we have a stud gun at work so I can bang a new one on at some point. Are they easy to work on without a pit? My old Megane was a nightmare, looked as though no consideration to service/replacement activities went into the design. Had to replace the gearbox and had to take out the whole lump to get the box out of the top.

But if your going for the dogs *****cks in engine builds.

 

then it would be fully rebuilt engine with uprated pistons, con rods, injectors, chipped and mapped ECU, Uprated turbos, Bigger inter cooler, hi flow rad, uprated fuel pump, and high flow fuel filter, boost controller instead of boost jets, lightened crank, lightened flywheel, lightened pulleys and sprockets, uprated head gasket, lightened single prop, bigger brakes to stop it, fully adjustable suspension with all upgraded arms and tie rods, new nylon bushes.

 

Looks like I got this then Ian..... :winkiss:

 

Alz. :sneaky2:

That looks the dogs danglies!

and usually something either breaks when taking it off, or you run into other difficulty due to age.

 

What, like exhaust studs....
