Probably around 250-275rwhp. Depends on your exhaust too, a nice 3" exhaust will get you closer to 300rwhp.

Question regarding engine management.

Suppose you swap a JDM 2JZ-GTE, can a USDM ECU manage that engine?

You can do that, but you need a piggy back ecu, such as an FIC, Emanage Ultimate, or a standalone to tune it.

Yes, except for the IC piping, and downpipe and midpipe.

Manifold, injectors, headgasket, etc will fit.

I have a gs400 and I am looking at the vvti or the non vvti gte, the most i do is add fmic and wastegate and bov. Im gonna run off the stock setup so my question is can i use the ecu from either of these motors and what are the obstacles besides wiring will i face by going non vvti. Where is a good place to get a motor i'm in florida.

Power braking system is not affected. Works just the same as it always does. 0-60 times, stock is 7.5sec. At 8psi you will prob drop that down to 5.5-6sec range, maybe faster depending on how you drive.

It all depends on your power goals and driving style...if your looking for a great street turbo so something with little spool up time go with a GT35R or if you want more power go with something like a PT67 or greater...

I have a blitz boost controller which recently started freaking out (not 100% sure its the prob though) so i'm gonna have jeff check it out hopefully its something simple. He bought the hks boost controller but mostly cuz he's a hks ho lol...You want to have something good otherwise if you get a boost spike past what your engine can handle u can say bye bye motor...

okay, heres a question that i've asked before but is different

I'm still considering the turbo vs. a Swap.

I figure the swap to be about $2000 (not including installation which will be done by my neighbor, Standalone, anything else so about $4-5k) and will get me to about 280-300hp.
I figure if I go NA-T that it will cost me about $4-5k and will get me to 300-350 hp.

But my problem is, I'm not going to want to stay at 300hp . I know when I hit around 400 i have to get the VB upgrade and eventually upgrade my internals. But my power goals are between 500-525 hp.

If i do the swap I'd keep it stock twins for awhile and save up for an upgraded turbo, upgrade injectors, fuel pump, all the good stuff


So would I be better off in the end with a swap? If not, would my motor hold up at 500hp?

thanks and sorry for the long post

to be honest i think you'd be better off with just a kit instead of a swap...you can find used kits pretty cheap now adays...you'll need to change your head gasket. this way you can be around 400 and when your ready to upgrade it wont be such a big blow...look at my.is for a used kit for around 2000 and then add parts you'll need to make 550hp
