Engine swap guide??
I work with a couple of tuning shops in Korea. The question I have is which Maxima engines are interchangable within the engine bay. I guess this includes the TT 300ZX engines also.
Samsung Motors makes a copy of ?4th generation Maxima (SM5) but supplies only 1.8L / 2.0L 4 cylinders and a 2.5L V6... I believe the V6 is nearly identical to the 3.0L V6 available for the Maxima. There are several customers who are interested in a complete engine / ECU swap to the 3.0L engine. How interchangable are the engines between the Maxima generations? Assume that one is not swapping the transmission.
My idea is to get the bell housing gaskets for these Maxima engines and compair them to the gaskets on the Samsung Motors' cars to confirm that a Maxima engine will swap into the tranny / engine bay of the Samsungs. What do you guys think??

It's possible if you get a whole front clip of a US maxima. This way, you will have the tranny, motor, all the harness and the ECU. I would try a VQ30DE (1995-1999) first since there are more readily available than the other maxima engines.

Well..
There isn't really anything you can just 'swap' into our Maximas. We just make do with what we have.
There's no point in replacing our VQ30DEs for SR20DEs.
The VG30DETT from the 300ZX is rwd, so forget about that immediately.
The VQ25DE is smaller than our VQ30DE, so again, no point.
That's why we've never made an engine swap guide for our Maximas. Even on the swaps that might be possible, they won't do you any good!
However, in Korea, you guys have a 2.5L V6, which should be the VQ25DE. If so, you should be able to replace it with a VQ30DE, since I'm betting there's few differences on the outside of the engine. The only thing I would worry about is the tranny. You said you weren't going to change it, though the gear ratios might be different, because of the different engine outputs.

VQ30DE... sounds good.
We will probably get our engines from Japan... the land of the cheap @ss used engines.
Thanks

The customers are looking for a cheap stealth look... the Police can be a PITA.
There are already a handful of the SR20 turbo conversions running around... some making in the 400-500 hp range. But that build up and engine swap is far from cheap. Used engines are cheap from Japan but high performance tuning parts are overpriced.

hmmm are you sure they are VId? in Taiwan
we get the VQ20DE, the VQ30DE, and the new VQ35DE
there are superchargers available for the 2.0 and the 3.0L, havent seen turbos except on the Japanese VQ25DETs and the VQ30DET
are ya gona be back this xmas Larry??

Interesting. Any websites or further info. My concern with turbo or supercharging the VQ25DE is the need for lower compression pistons and fuel/ ignition control.... Korean premium is 94 RON or 89 AKI octane.

Running above 9 pounds of boost, I'd recommend to start building your internals

yup the VQ is a pretty solid engine for being a high revving light weight aluminium block engine

The only kit I see for superchargers is Stillen's but it is way overpriced and made to fit the VQ30's...

Doesn't sound like anything written in stone. So is it mostly hearsay. I am looking for hard numbers... dyno runs, ECU modifications, injector upgrades, a/f ratios... the works.
