Had that asked a few times, so here it is:
Ok so to answer the question of how much Im personally in it (Including the brand new engine, trans, all of the turbo stuff so far, all of my visual car upgrades including the CF and exige roof, and my seats, Im in it at just under $30k. But keep in mind that’s everything and a lot of new stuff that is irrelevant to someone who would be doing this.
So ballpark how much would it cost to do the 2gr NA swap? Not as much as it appears:
Depending on if you go used and deal hunt, or go for new and best of the best makes a huge difference. Ive seen junkyard 2grs go for $1k all the way up new ones being $4k, if you can find a E153 out of a junkyard MR2, you can get them as low as 300 if youre lucky, or you could buy a new one for peace of mind for 2700. So much variation in all the components leaves a huge variation.
Also, if you sell your old engine and transmission for another 2k, you offset the cost…
Deal hunting, used parts, doing a lot of the stuff yourself, selling engine trans and all removed components: Under $8k
MOST LIKELY COST:
Buying fairly new decent condition components from junkyards and ebay, an averagely decent 2gr engine that comes with the harness, a new trans, buying the MWR conversion components, fabbing an exhaust and selling the old eng and trans: ~$11k
Doing exactly what I did but without turbo and only the engine swap: just under $15K (selling the old engine and trans for 2k bringing it to $13k)
Turbo and all supporting components, Almost all new components, almost new engine, new trans, all the components for the conversion from MWR, AIM digital dash or comparable, and built engine: Probably 25k+ (yet to be determined
Heres a general breakdown:
~$2500 :2gr Engine
~$2700 (new) E153 Transmission (500-1500 used if you can find it)
~$500 engine harness and wiring (assuming engine doesn’t have it)
~$1250 Full exhaust (DIY welded by you) (3k from MWR, 2.3k from 2Bular)
~$700 Digital dash (koso) (~800-2.5k for other digital dashes) (not needed if you can figure out how to run the OEM dash using sensor to CAN converters)
~$800 for clutch and flywheel (~300-500 used OEM) (assuming engine doesn’t include it)
~$1300 Axles (from MWR) (or you figure out the combos of hubs and CVs from others would work, or have custom ones made.
~$600 shift cable adapter (from MWR) (unless you fab one up)
~$40 for DBW gas pedal
~$500 in engine components (alternator, starter, ac comp etc) (assuming your engine doesn’t have them)
a SH*TTON of time (less if you buy an exhaust and have the wiring done for you though.
Ignoring my time working in the cost though. The two most time consuming things was designing and fabbing the exhaust (wouldn't have been as bad if it was UEL headers) and researching and going through all the wiring of all the components.
If you want an exact price list I can show you what Ive paid (I keep an excel sheet) But basically swap alone Im in it so far (not including the turbo) at $14800
