Is there an engine other than the vh41de that can be installed in the 97-01 Q?

[Marshall206]

vh45de?vq30det?vq30dett?vk45de?\

any of these a possibility? heard a lot of talk about it but has anyone actually done it, thinking about ordering a pre-owned vh41de and just building it up as best as I can, but would love it if I could order a small 6cyl that already is turbo, thinking the best way to get some real power out of the y33 would be to get a smaller engine that has comes turboed and just switching out a much larger better turbo

I know there is a lot of talk about this but I have money and a very capable mechanic/engineer , just need info before I can start researching further.

so the sumed up question of this thread is ....

will the 30dett fit easily? what would be involved?

will the vk45 fit easily? what would be involved?

will the 30det?

or the vh45?

any info woud be very much appreciated, my q is very far along interior and exterior wise, now im finally ready for some major engine mods, and from what ive seen nobody has done much with the 97-01 q, not sure why the vh41 is a great engine, but anyway I have the resources to do it so plz help.

Thanks,

Clean Air Act prohibits swapping engines which were never sold in vehicle as an option. Larger than oem engines are forbidden since they produce more emissions.

You might get away with downsizing [without boosting] since EPA referee understands smaller is better BUT in 1996 and later you run into OBDII which prohibits swaps period.

If improving MPG is goal, unfortunately even a 27% smaller 3.0 liter will need to turn higher rpms [than 4.1] to generate enough HP/Torque to cruise so after all the work you are lucky to gain 1-2 MPG at best.

Maybe because yours is not running? It is very smooth and free revving.

You need to look at Impul (headers and ECU) and JDM VH41DE (better headers and spider intake) while realizing that it is set-up for RHD. Start in the VH/VK forum. If JDM parts will fit a LHD chassis, then $10K might net you 20 - 30 HP. Figure $30K if you are doing a bench build for 40 - 50 HP. A VH45DE would be best, but how would you adapt it to OBD II? A VK45DE would be easier, but again, one would have to compare OBD II ECU connectors.

But how will you pass WA emissions?

Please let us know about your progress.

[Marshall206]

so my 2000 Q45 would not pass emissions with an engine from the 2002 model? seems wierd, and why would there be a law that prohibits me doing this? Ive done a little more research and im looking more and more at the engine from the 02 Q, but I was not aware that emissions would be an issue.

What if someone took every component from a 2002 and put it into the 97-01 chassis, the 02 claims 330 or so horses and it passes emissions fine, and if the engine is somewhat compatible an engine swap wouldnt be too pricey as far as the amount of power I would get, just the stock vk would make a huge difference.

anymore info would be greatly appreciated about why I would fail emissions, or about what troubles I will run into with a swap like this.

Thanks

OK, But the 2002+ Q45's are so new that they are basically none in junk yards and finding a motor is as hard as putting it in your Q45.

but if you can pull it off you will have a fast *** Q45 because yours was suppoesdly lighter which made up for the loss of engine displacement, and a lighter, stock looking Q45 with a VK45DE is going to be a hell of a car.

But the 1997-1998 should have it done because those look the best of all the FGY33's, There rear end looks nice.

But still the FGY33 is a Q41 in my mind.

No offence.

[BadQ45t]

No offense taken, the Q41 has better looks and conformt that then first gen and there is no comparison in reliability. I had a 1992 Q45 and while it was a very cool ride I will take my 97 over it any day.

As for your plan to replace the motor, drop it, too much work and not worth it.

The Y33 Cima comes with a stock VQ30DET so it will fit.

Now the question really is - can I fit a VH41DE to my Y33 Gloria? The wheelbase is 30mm shorter and the Y33 Gloria never came with a V8

There was never a Y33 Cima! All Cima are FY33. All Gloria are Y33.

The US (nor anyone else outside of Japan) ever saw a Y33, but the US did get a version of the Cima in the FGY33 Q45.

Low line Cima did utilize the VG30DET and VQ30DE.

I'll take that as a "no" lol. Guess I'll be looking at the VQ30DET then. For me there is no way I could do an engine swap that can't be done with stock parts. Even a direct swap will be a huge challenge for me.

BTW the base model Cima in that generation was a VQ30DET. No non turbo V6 and no VG model.

[maxnix]

Earleir used VG, then sometime around 1998 they introduced the VQ.

Don't know exactly as since they were never offered here, mere trivia for me.

Isn't the 03-04 M the same platform as the Y33? Couldn't the VK from that go in "pretty easy"?

[Infinitiguy19]

Are you looking to be the "first" with another engine swap on your car or are you looking for more power?

Did you think of rebuilding the engine and putting a 5 speed in it for less HP loss?

What about adding a turbo or a super charger?

Turbo is the eaiser route on your car I think.

Either way good luck.

[NJ 666]

You could piss everyone off and put an LSX in it...

[maxnix]

The Y34 is very similar. Only the US got the VK45DE.

[BadQ45t]

Turbo or Supercharger makes the most sense....an engine swap would be just way too much work. there are custom shops that do that sort of think, probably run you 5k or more but a good turbo would be fun.

[Marshall206]

I think if the engine swap was possible, it would be much more effective then doing a turbo or SC on this car, with turbo or SC the car wont be as reliable, but with the 02 engine in it it would pump as much power as you would probably get reliably with a turbo on the vh41, and for the "no offense" thing about the Q41, I dont take any, I chose this car for a reason, its looks, and the fact that there is only a few in Seattle, and the older q45s just dont compare in style, I simply just want more power, I would just sell my 2000 and get an 02, but I am not a fan of the way it looks, I think the FGY33 body style is timeless, and even newer cars just dont have that look.

I think my route is to research more on the vk45, as I have already found a totaled one with a 58k engine parting out, and I only looked for a few min.

So anymore info on swapping to an 02 engine would be appreciated, mainly from Q45tech or someone who has vast knowledge, and I looked into the clean air act you speak of and it doesnt seem to be a problem according to several tuning shops around here, not sure where it is you are located but several have spoken about q45 enigines being swapped into 300zx, or skyline and still used for street.

[maxnix]

Study the Y34 (or just buy one!) as it is very similar to the FGY33.

[elwesso]

not sure why you'd pick a VK45 over the VH45.. VK45 makes the same power as the VH45 (despite the numbers, remember numbers are just numbers).

Honestly the EASIEST thing for you to do is just to swap VH45 internals into your VH41 block!

I would try that and some headers, and a high stall torque converter and see how that treats you.

[maxnix]

Actually, I would go the other way and install the JDM style VH45DE plenum and the better flowing JDM headers if possible. VH45DE headers will not bolt on.

Probably have to migrate to a JDM or Impul ECU for the improved flow.

[elwesso]

the JDM VH41 manifolds really arent that much better than the US vh41's theyre not the tubular kind like the VH45.

[maxnix]

Exhaust? Only a little better unless one built headers.

Intake? JEM is a spider just like VH45DE.

[Marshall206]

If I swapped the internals to give my 4.1 a longer stroke, how would this affect actual horsepower? and would I be able to go with other performance parts made for the vh4de? like the ECU? or a turbo like others have done to the 90-96 Q?

[maxnix]

It's only money!

The VH45DE has a stronger design for the crank.
