no shop is going to have all the custom stuff you need. you need to make it yourself. if you can't do that, you can't do the swap. i must reiterate, THESE CARS ARE NOT HONDAS, nor are they like muscle cars. you don't just drop in the engine and fire it up. you are setting yourself up for failure.
Also, please try and use proper punctuation and sentence structure. huge run on sentences are annoying to try and decipher.

a VQ is a better engine but needs the compression dropped a bit for forced induction. They dont have the bennefit of the steel block but they wouldn't need it with lower compression and proper fuel management.
but seriously, I think I'm going with the CA18DET. That's a good engine. Light weight and better weight distribution. 48% front, 52% rear

lmao, VQ better than the VG. go post that in the Z32 section bleach. lol. it was designed lighter, thats it. beyond that its not a strong motor.they got alot of juice out of it being an NA V6 but thats about it, its not a better engine. VG30DETT FTW

yes, the sleeves in a VQ aren't made for over 800hp but there are plenty of VQ's running twin turbos and putting down 500-600whp on daily drivers. Not even a 'lot' of people with a 300ZX TT do that just because of cost. Z32 drivers like to point out a VQ doesn't hold 900hp. I seriously doubt 1% of those people have the funds to push 900hp out of their engines. Its just easy to put down someone else's car online when you can't afford one.
VQ has far more technology in it than just being lighter. The VG30DE is basically a larger Pulsar engine.
The strength of the block is not the only way to judge an engine. By those standards only an L20b is better than a VQ...

actually without a real low comp rebuild on a VQ ive seen no dailies over 500hp, and many destruction videos. they dont hold well to boost, and other than a V8 or bigger how many other motors can get any really respectable numbers? yeah, exactly... that was a bad point to make, but its ok, i still like you, even if you did turn to the 350 side.... aka the dark side.

just in the short time I've owned one, I went to a meet. One guy brought his G35 TT with a dyno sheet. 558rwhp. Its his daily.
That's how we do it on the west side.
I'm keeping mine stock though. 250whp is enough for now
Seeing a couple videos on youtube doesn't give you an idea of how they blew. Some kid can bolt on a $5000 turbo kit and not change the ECU. Then his dad gets stuck with the car payment on a three fiddy with a blown motor.

that doesnt sound like all youll need. either way, thats like 3k in labor and parts right there. and you dont need any turbo timer, wait with you car 3 minutes and turn it off yourself. also, why a jdm ecu??

FMICs suck on the VG30DETT.
why do you need a JDM ecu?? there is absolutely no benefit. none.
blowoff valves are not needed on the VG30DETT. it has stock recirculation valves. they are the better choice, unless you want the ricer sound.
wheel spacers suck and are dangerous. get wheels that fit.

What good is one blow off valve on a twin turbo car?
Why do you think you need to cut the firewall?
What do spacers have to do with your twin turbo project?
HOLY CRAP! You haven't got a clue what you're doing. I expect this project of yours (if you even get started) to run easily into the 10,000 range.
I swear to god some people shouldn't breed.
