Tom, I noticed you live in ca... isn't it a pain to go FI here (having to take off the parts for smog sux)?

The short block is tempting...my engine runs fine but I am looking at it more with FI in mind.

I should consider collecting parts and possibly rebuild the engine myself. From my reading, the 1uz rod should replace the 3uz... stock piston should be good enough. ARP bolts is a must.

LOL, eventually I will do it. I'll just call it a hobby... unless the 4gs-f comes along, I'll stick with modifying the 2GS.

I also built some motors in my time. But I will tell you that the 1UZ is definitely more complex than most people think. I just built mine and parts alone cost about 3k. Just for the bottom end. (coated pistons, rods, bearings, misc. gaskets. water pump, etc.) Machine work cost me about another 1k. If I had to pay for the bottom end to be built, it would be about 500. Looking back at it, I might have just purchased a block from Eric (Cowboy) or from David (Lextreme) but I wanted to go through the process of amassing parts and watching it come to form. It does take time and since aftermarket parts aren't as readily available, it does take time to get them in.

I know, i never said it was cheap. was just letting him know of a another option but remember you have to pay to play sir

i did and anything is possible but costly is probably the killer here... u could do it in that awesome gs you got....could be 1st in the us with the 3g swap AND a 5.7

cowboy looked at it, and said no. the 5.7 is just physically too big to be fitted inside the engine bay.

This may be getting too off the current thinking, but if you wanted larger displacement with the current motor, I know that there are stroker kits out there to make a 4.0 to 4.5, and 4.3 to 4.7. Once again this is extremely costly, but I think I may be getting too far ahead of this conversation. Just some FYI.

could you possibly massage the engine bay and fit it? or will it just not fit without spending a ton of $ to make it fit?
