Going with a 1jz
 

Recently blew the Fa20, just over 36k miles.. been debating on what to do with the car and came to conclusion I'll be doing a 1J with a R154 tranny, still haven't purchased the motor or anything for it just because I'd like to shop around and not jump into. more likely I'll be piecing it slowly. Gonna start this awesome project in the next week or two! The motor as it sits currently

What turbo kit and what was your set up? How much boost/what gas etc...

vvti or non-vvti? 1j is a a great choice!

Still curious on what you were pushing and what fuel you used the majority of the time

why bother with the 1J instead of a 2J?

I had a 1jz twin turbo in a car that weighed about 600lbs more then the FRS and even with the 1jz being stock the car was a rocket... one day my FRS is getting swapped

it has been many years, but I heard something about the 1jz head having better flow or compression or something, and you could swap it onto a 2jz block and make a 1.5jz. There is no punch line to that, I just thought I would throw it out there.

1.5J is a waste of effort, 2J head has been proven to flow better stock for stock. The reason people do 1.5J's is to retain their existing 1J loom, plenum, big single manifold etc.
I've built a heap of cars with the full range of JZ motors, my favourite of the lot is a vvti 2J with big single setup.

looks like you shot a rocker out. its a problem with stock valve springs and high rpm/power. usually doesn't cause any valve/internal damage though

A third the price? Easier to find? Cheaper trans?

Nope.

It was also done in Japan to be sneaky and get more displacement (as their licence levels are based on displacement)

Not cheaper anymore as the supply is drying up. Not easier to find as we never got the 1JZ here. Trans doesn't matter as the R154 will bolt to either so long as you have the right bellhousing.

The real issue (as usual) is getting everything working (if the dash doesn't 100% work, it's a shit swap IMHO). If you're going standalone to get everything to work, and you're going custom on the turbo install, it's a hell of a lot cheaper use a 2JZ-GE long block and boost it (or build it for boost). The GTE head is nicer but it costs a lot more...

You can get 1jz's up here all day for 1000-1500$, which in american cash is what, 100$? Buy one up here and ship it down, not hard. 2j's run 4-5000$ without a trans.

This but non-vvti :)
