Guys from reading this whole thread right up till now I gather that;
But before hand let me tell you that I'm running a 4G93T with TD04 that is modded with bigger FIN, 38mm wastegate, ECU that has rev-cut set to 10k rpm and no speed-cut.
My target that I would like to achieve is a modest 250whp.
1) Its safe for me to use standard GSR (4G93T) internals and boost till says not more than 1.4/1.5 bar (20.30/21.75 psi) with proper fueling and tuning. How reliable is the 4G93T internals?
2) Will E-manage be sufficient? Since this is a road use car so i guess it will be okay. Maybe it'll see 1 or 2 track days (if my wife permits la :p)
3) I currently have a 1.8mm metal gasket that is taken from my old 4G92 DOHC Turbo. Can I reuse it back here on the 4G93T? or is 1.8mm a little bit too much?
4) I'm planning to dump in a 269 degree camshaft. From my user standing that 268/269 is street-racing cams, am I rite? Or what do you guys recommend.
5) I'm planning to perform an engine balancing. My question is, what do I give the balancing shop? The block, crank, flywheel, clutch cover and clutch plate, conrods and pistons only rite? Or do I need to give them the new main bearings, piston rings and also conrod bearings?
6) For engine head port and polish, what do I need to give them? Engine head and new camshaft rite? Do I need to grind in new valves also and do I provide them the intake manifold so they can port and match in to the intake part of the engine head?
7) Last question, how much will the engine balancing and port & polish cost me? I want a good and reliable mechanic / shop to do it for me, any recommendations? Do I need to also lighten my crankshaft or lighten my flywheel?
Thanks for your answers in advance :)
