engine swap

what would be the best engine for my 1992 infiniti g20 when i take my stock engine out. What about would it cost.

Best engine for what? Performance? Probably the SR20DET, cuz it'll fit best (since you have an SR20DE) But you have to get the engine imported from overseas, then its a pretty long installation process. ANd if yuo can't do it yourself, It'll cost more than the car is worth to do it. Just for the labor.

As stated above an SR20DET.. Out of a GTiR, Bluebird, or Avenir will be sweet...

There is a write-up on SE-R I think it was....

Hang on, it's in my history, I'll get it...

Got it

Here's a few collected thoughts on a typical SR20DET engine install hopefully these tips will make your job a little easier.

The actual swap of the engines was pretty straightforward. Disconnect parts A, B, and C to pull old engine, reattach A, B, & C after installing new engine. The hardest part was just figuring out what components/sensors needed to be transfered over and troubleshooting. If you have an FSM and label what you disconnect that will help a whole lot...

This info was based on a Bluebird DET engine
What to swap:

DE distributor
DE main wiring harness
DE fuel injector wiring harness
DE temperature sensor
DE throttle position sensor
DE air-idle control valve (extend wire)
DE O2 sensor (you will need the O2 sensor adapter nut off the DE exhaust manifold as well)
DE flywheel (if using a DET from an automatic)
DET power steering 90° bend onto DE pump
DE AC bracket
Sentra DE throttle/cruise control cable bracket (for 95+ SE-Rs)
What to fabricate:

Intake piping
Downpipe (3" or 2.5" id)
What to buy:

JWT ECU w/ turbo program (model year specific)
A new clutch and stronger motor mounts will be needed, best to do it now while you have the engine out
What to modify:

You will need to extend the wire for 02 sensor on manifold
Upper flare nut on the master cylinder needs to be ground away a little to clear top mounted IC piping
Crossmember will hit the tranny in one spot, it needs to be dented in a little
Battery moved to trunk or reoriented in engine bay for extra clearance
EGR is capped off (there is no provision for EGR on a DET)
Install notes:

The solenoid for the charcoal canister has one wire and 3 vacuum inputs: 1st. is from intake after MAF, 2nd. is from the top of the canister, and 3rd is left open
When attaching the DE tranny to the DET block, two of the mounting bolts will no longer be used
Right side halfshaft support bearing will only line up w/ 2 bolts, that is okay
For the 95+ it is possible to remove/install an engine while leaving the AC system still sealed up.
The 95+ AC line will be a tight fit but can be pulled back out of the way of the IC piping
The engine was pulled/installed from the top, we didn't even remove the hood. Others have had equal success removing the engine from below.
This should be most of what it takes to get you out the garage. There are things like guages, hood scoop (or MUCH better, a front mount intercooler), cleaned injectors, new EGR hookup, etc. that can be done to improve reliability, power, and emissions. These are important issues so intelligently determine what should be done now and what can be done later.
