Easy.
1JZ VVTi with full dog engagement set R154 and Twin plate, HKS 3037 pro kit, injectors, cams, PFC management etc... Full new rear end inc. Moser 31 spline billet axles, 4.3 gearset, Kaaz 2 - way mech, rose jointed trailing arms, Full 12 point cage, Seam welded, tubbed front end, perspex windows, Brembos, more 18 x 12's for the rear to match what I have........
apart from that Im pretty content with what I have.
Windows/cage/tubbing and new rear end are being done in the next 6 months anyways, and when the 20DET finally dies a 2j is going in.
The KE70 on the other hand....
forged build 20V 4age with full MCR Quad flat slide carb kit and HKS 304 cams, Cusco headers and straight pipes, twin plate and W58 supra box, T18 rear end with TRD mech and 4.5 gearset, GReddy AE86 coilover kit, Full respray in White Panda, JDM quad light front end, chromed bumpers and TRD front splitter, full cage, Recaro's from the 31 into it, and a few more sets of 15 x 8 -4's for plenty of skids.
That should dent my bank balance quite nicely.
