Some random info about R33s (based off my own car).
Key Blank Master: KEY00-00118 (Nissan Genuine)
Brake Pedal Stopper: 46584-S0100 (96 and onwards) 46584-5P010 (95 and prior), though, it is noted that 95 and prior one fits in the 96, and may be found cheaper, so ask for prices on both.
Oil Seal (Front Crank and Camshaft Seal): 13510-10Y10 (Nissan Genuine)
Timing Belt: NS-141YS25B (Greddy), 13028-20P10 (Nissan Genuine)
Tensioner Pulley: 60TB0732A (NSK)
Idler Pulley: 56TB2801B01 (NSK)
Fuel tank has a lock ring which can be a pain to get off without a Fuel Tank Lock Ring Wrench. Nissan has a version of it (KV991 04700), but I think that the Lisle 63000 will also do the job, will update this section when I get one to test with. If you're ordering a pump or doing any work that requires removing this, it's well worth the $30-40 for how much of a pain it is to try and remove and fit again with a punch/wood block and a hammer.
Stock: UNISIA JECS A42-T24
Replacement that fits fairly well is the Walbro GSS342. I found I could keep the bracket intact (bit of a squeeze, but not overly so), used the pickup filter from the old pump, the hose joiner too, soldered the plug from the new pump onto the old wiring and dropped it back in, seems fine to me.
