http://www.supraforums.com/forum/forumdisplay.php?f=77 <~~~1jz/2jz section.. i know its mk iii but can provide alot of useful info!!!


i have only seen 1 other mk iv with a 1jz so its kinda rare.... my only question is... y did you chose to go 1jz?? for the price of that you probably could have gotten a good single turbo kit for the NA, there are ALOT of high HP NA-T cars out there!!! im not trying to rain on you.. just wondering thats all

that being said, just about any shop can do the swap its just a matter of time frame?! and $$ for install


also, is your car already a M/T?? if so u will probably have to use the 1jz bellhousing and your transmission.... if so im willing to buy that r154!!!!!!! i beleive that the mk iii and mk iv transmissions are different lengths

good luck with the swap and let me know if you need any other info!!
