Stage Tuning; Skyline Gts

[J-Spec Sweden]

Hey guys!

As I am into upgrading my R33gtst I'm quite interested in wich parts to change at the first stage. Have plans of getting into some more serious tuning, but at first, what should I go for?

Let's say 1. Without changing original turbo, first parts to install/replace?

2. Without upgrading turbo, but harder tuning?

3. First changes after turbo/together with smaller turbo upgrade?

4. How far can I go with my RB25DET?? Parts for really serious upgrade?

Really enjoy your site, lots of information! Skylines is getting more and more common here, and there now exists around 200cars in the country.

Thanks for your time!

My usual order;

1. Choose you power target and usage, and only buy parts that meet that power target and use. If you don't know your power target and what you want to do with it, you will buy the wrong stuff, waste a lot of time and money.

2. Exhaust is always first, the most important upgrade on any turbo engine.

3. Intercooler (since it's not a GTR) the standard intercooler is quite limiting.

3. I do ECU (with boost control) at this stage as I gain a lot of power and improve the fuel economy. If I just turn up the boost the fuel economy turns ot crap plus it fouls plugs, hits rich and retard mapping etc etc. The standard ECU can be very frustrating, takes the enjoyment out. If you power target is over 225 rwkw it will pay to do the AFM upgrade (to Z32) at this time as well.

4. Airfilter, what you do is entirely dependant on your power target, but don't ignore heat shielding and a decent cold air feed.

5. It's turbo time, carefully choose one that meets your power target and response requirements. If high power, you may have to do the exhaust manifold/wastegate at the same time.

6. Cams, Tomei Poncams are hard to beat up to the limit of the standard internals.

There is far more detailed info on the forum, the search button is your friend, it is pretty unlikely that you will think of a question that hasn't been asked before. Try this link and its links for a starter;

There is a sticky thread in this section.

Forced Induction - Quick Ref Guide

read the links in there. It covers most of what you probably need
