Increased efficiency of your air intake system by replacing the OEM air filter system with an open filter. Most of these are giving you power increases by making the affected system more efficient. Although you still will need some tools and ability to use them. No special tools usually needed and do not need technical adjusting or tuning, etc. There is no set rule on most of this and you need to go back to having a PLAN to reach your GOAL within your BUDGET (remember page 1!). So for much of these categories the higher in the list it is done usually means to do it first or at least sooner than items at the bottom of the category list. Using the aforementioned spreadsheet method will also help you get your goals better identified by, if nothing else, showing you the costs as they are added up.īOLT ON, SOME INSTALLATION, MECHANIC INSTALLATION, NEED TUNING FOR (power producers), OUTSIDE AND WEIGHT, BRAKE & SUSPENSION, ENGINE INTERNALS, and OTHER. Because otherwise you might very well do something out of order in such a way as to waste labor, money or usually both. So once again - know your end goal (or at least a darned good idea). While you can just DO IT and then wait until your stock bottom end fails you (thereby needing to pull the engine and rebuild it), many choose to not purposely do that. If you are truly going to build for, say 500ish AWHP then you should give consideration to your engine internals (covered on page 5). I will TRY to lay it out in a easy to follow manner but realize that while there is some reason for the order you can also sub in this or that during different times.Īs previously mentioned, you need to know your goal.

Many things can be done at certain times while others require previous modifications to work or operate properly.

There is really no "staged" way of listing performance upgrades, modifications or builds. Or other aftermarket power and efficiency modifications. PERFORMANCE STAGES & UPGRADE LIST for the 3000GT VR-4Ī comprehensive list of parts starting with bolt-on hi-performance parts
