2. I'd suggest that we agree on an overall plan for your build before we get into specific brands/links:
   
   You asked "...where can i start for building the engine?...rods, pistons, etc.". The exact answer to this question is: nowhere.
   
   Please allow me to explain. You should definitely NOT start by "rebuilding the internals". 100% for sure. Please, please, please, please (!!!) tell me why you think you need to start by "rebuilding the internals"???? 700rwhp is a walk in the park for a bone-stock 2jz-gte!!! Really!!! In theory, you could even roadrace it at 900rwhp and it'd be just fine with oem bone-stock "internals"!!! I MUST find out who keeps spreading the nasty rumors that the 2jz-gte internals need to be "rebuilt" in order to handle power. Who on earth told you that - where did you hear that or how did you get that impression? Please help me track down the source of this nasty rumor. Sigh.

Next, note that the bone-stock Mkiv TT suspension is also just fine for roadracing too!


To build a 700rwhp daily-driven + roadraced Mkiv TT, here's what you'll need:

• Turbo kit (~67mm)
• Aftermarket cams (264s)
• Fuel system upgrade kit*
• Engine management electronics (piggyback or ecu replacement)
• Wider rims (9.5" front, 11.5" rear)
• Aftermarket exhaust and midpipe
• Aftermarket intercooler
• Aftermarket clutch (assuming you'll be roadracing a 6spd)
• Electronic Boost controller
• A budget for race fuel (110 octane), or alcohol injection system

Aside from other minor odds-and-ends**, that's pretty much it. Notice my list has no "internals" (unless you want to count the cams). It also has no suspension upgrades. Again, both the oem 2jz-gte and the oem Mkiv TT suspension are just fine for roadracing. If you're super-serious about regularly roadracing, you'll eventually want to invest in some Penske's, Moton's, or Ohlins's...but to me, that's nothing you need to do on the initial 'build'.

*If you set your goals down a bit to ~650rwhp, you can even skip the fuel system completely and go with a big alcohol injection kit instead. This will save you $$$ on race fuel. However, if you have 750rwhp+ in mind eventually, there's no way around a full fuel system upgrade and race fuel.

**Other minor odds and ends include things for circuit track days like an aftermarket driver's seat (holds the driver in position better for roadracing), a 5-pt harness bar (and 5pt harness), roadrace tires (R-compound) for track use, special fluids (diff, coolant), etc.

Mostly Dover not many roadrace tracks in the well actually no roadrace tracks in jamaica =(

I cant really find the rest of the sites i visited to but this is one site that i managed to find after about a hr or so of searching my history
http://www.mkivsupra.net/vbb/showthr...2JZ-GTE-engine

Thats what i recall made me think that the engine needed to be rebuilt and also the thought of having a good foundation for the power.

So for the overall plan where do we start?
