i got a 2004 is300. completely stock at the moment. im looking to just have atleast 350-400hp. i dont know much about cars at all. lol but i was wondering which would be better. turbo charging the is300 or just going with a swap with the 2jzgte??

build the existing motor... easier wiring wise, fitment wise, etc...

then turbo it...

what do u mean build the existing motor??

The engine block and crank are the same between the GTE and the GE motor, minus oil squirters that the GE doesn't have or need. Replace pistons and rods and you essentially have a GTE that doesn't require any special wiring...

hrmm..thanks man! i'll look into that now that ive found something out. lol ohhh and how much do u think i'll be looking at after rebuilding all that stuff??

For only 350-400whp that's very achievable going na-t. Anything above 400, I'd recommend a head gasket and arp studs. I'm a big fan of gte, If you ever decided to want more power, I'd much rather go GTE. Wiring can either be paid by a professional or if you understand schematics you can do it yourself with little spending a on electrical part.

Care to elaborate why? There is zero notable difference in the block and crank minus oil squirters, which we generally disable anyways...

It's a better platform IMO! Lower compression, head flows more I believe, and you have the better intake manifold front face. I'm talking big power. How many big power na-t 6-1000whp do you see? I made 630whp 22lbs in my gte without a single hiccup. I enjoy gte's!

Actually, low compression vs high compression doesn't matter much any more... High car = better spool and less boost to make the power... Also, not by much, but the GE head flows slightly better than the GTE head...

I'll give you one on the ffim, but there I can be a lot of work to make that work too... Pistons and rods are the only real difference, and if you are going to make over 500-600 completely reliably, all the time, its worth it to build the motor anyways... Sure GTE stuff will get you there, but there are instances of that stuff failing at relatively low power levels even with good tuning...

Boost_lee

Nothing against na-t. But I've been around gte's for a very long time and I myself has made good power on stock LONGBLOCK. Tres made 960whp on stock block! That's just my point, the reliability of a gte without having to build it is amazing, of course tuning is another topic to be discussed.

Sorry, phone double posted...

No doubt the GTE is a tough motor... But do some research, for every person who made 900 on one, someone wore one out at 600... Also, where to find a good shape GTE without spending a ton... Half the swaps from Japan are junk and need gone through anyways...

Boost_lee

Many warehouses out in Dallas has never done me wrong for all the jz swaps I've done. I don't do much research on the forums here because we race our cars every weekend with over 5 of my buddy's on gte's pushing over 600. All our numbers are still 160+ on the boards. Regardless, GTE is a much better platform than a ge.

So you have no experience with a GE so you are scared of it and don't know... I get that, but don't spread fear and doubt because you don't know...

Boost_lee

Never had experience with na-t. Seen many guys do it that didn't last. That's a fact. You can say all you want, at the end of a day, GTE'S IS A BETTER PLATFORM. If na-t was so badass, why arnt they the most common swap done? Because at the end of the day, if you want it done right the first time, gte is the way. You don't see boost logic, Titan, many other big shops bragging na-t because its not the best platform!

Boost_lee

And by the judge of it, you have a GTE is300...point exactly.
