Default 1jz or 1jz vvti?

alright guys here´s my issue i have a 93 toyota soarer with its stock 1jz twin turbo engine auto transmission but it just so happened whe i went out to purchase my 1jz 5 gear tranny my engine started over heating shutting off long story short my block is in a better place now! well i need a new motor but not quite sure of which to go with either the stock 1jz i had with a mec. tranny or a more modern 1jz VVTi mind you this is a drifting project.So if you guys can give your 2 cents i´d be a happy camper

Assuming the head is still good you could find a local 2jzge block for more torque.

If the bottom end is shot, just get a 2j bottom and make a 1.5 j.

VVT-i is superior in every way, not to mention the fact that your engine will be much newer than an old dusty 1JZ non-VVT-i engine. You will want to do some research to see what you have to do to make it link up with your current setup.

^^^^ this is not true, we can all look at the specs and see that yes it has 400 Ft lbs at 2400 RPM but the Tune-ability and secondary market for parts is limited. Maybe i dont know what im talking about i only have 2 of these.
Power is power. The VVti has a single, Take the Twins off the 1jzgte and make single,,,,, Holy Crap you have 400 ftlbs welcome to the real world. any 1j 2j with a decint size single should support this power goal. just get the regular 1J or do the 1.5J conversion. BTW my raceteam manager just bought himslef a VVTi so we will see how it turns out. Hes not going to do anything to it but run it hard in a drift car.

1.5 J = Good
1jzgte = Good
1jzgte vvti = Good
Just dont try and feed poeple bullcrap about superiority or we would all be rolling VVTI

1jz great motor old but can be revived to hold. Limits if once you go single you get lag. Nothing saving you there

1.5jz great motor built or not. Limit once you open the motor you will start building it and mess up your budget.

1jz vvti great motor. You will have a more spool responsive motor rather you upgrade turbo our not. Downside is the price and tuning.

I suggest you read the following website. CLICK Unless the website is lying it's quite clear that a large fraction of the gains are from VVT-i.

AEM can support VVT-i.
Titan Motorsports makes VVT-i cams.

Tuning and cam availability are the two biggest issues with going ***** to the wall on the VVT-is. I suspect once more companies follow suit and start supporting VVT-i we'll see more builds. Aftermarket suppliers will have to because most modern engines are now coming with VVT-i.

1JZ-GTE = Good for it's purpose
1JZ-GTE VVT-I = Better
1.5JZ = Bad Idea. Higher displacement of the 2JZ offset by lower flow capacity of the 1JZ & by lower rev capacity of the 2JZ.

Feel free to explain this? I say that because I'm completing my 1.5jz. others on this forum and many other forums would disagree with the bad idea statement.
