all though .. I love the 22R , RE series engines there is NO horse power there .. I built many engines ,(including TED'S parts) and top H/P , costing about 4G'S + + was about 150 FWHP ~ 180 FWHP .. really NOT worth the expence .. to make it GO GO .. you need to do gears , and a wrath of other pieces ..

for minimal/comparable cost , you could stay with toyota , and do a 7M/7Mgte , or 3VZFE , or even a 5VZFE .. (which i'm doing in my Trekker) .. I will also be able to add the TRD supercharger , to a tune of 240 FWHP and with computer mods .. 300 .

I say SWAP .. unless your keeping it "stock" for resale ..
