z blasphemy

[zlova]

this is a hypothetical and last resort question?

recently on top of the wrecked1990 300zx that i just aquired, i also bought a 1990 nissan maxima, that at specs has a compatible block.

now the 300zx has 222 hp while the maxima has 160, if i could not repair the damage to the 300zx could it be at all possible to put the innards of the 300zx into say the maxima chassis to provide the additional horsepower?? because as of now it seems the engine is pretty much a boosted version of the maximas? i do realize the maxima is fwd and that the z is rwd but shouldnt the mounts be compatible?

also if this be the case, could the innard of say the maxes engine be fitted into the 3oozx block to get around the high compression issues with fitting an aftermarket turbo onto it? thus lowering the compression ratio and allowing for an aftermarket boost solution?

well, if i am not mistaken, the 1990 maxima has a VG30E in it and the 1990 300ZX has a VG30DE in it, so i know that the maxima is SOHC and the Z is DOHC, now, about the pistons, rods, and crankshaft being exchangable, it *might* be, but very unlikely.

... Man you're talking some insane fabrication work. I don't know what to think about this one, it seems a bit pointless to me.

lots of custom work...

we are talking swapping cross-members, custom tranny mounts, motor mounts, everything...

too much money and not worth it at all. you have to remember...the maxima is a FWD car and the 300zx is a RWD car. making everything work for either or would take alot of fabrication with the crossmembers and mounts and trans configutation

i have a friend who took a wrecked turbo porsche 911 or 944 and then put the guts into a vw golf mk 2 frame.

maybe too much work, but if i cant fix the frame. ill be darned if im going to let that engine go to waste.

thanks guys

if you feel its worth a try go for it...but in my opinion it would be cheaper and easier to just upgrade the motor in the maxima. or buy another Z32 chassis with a blown motor and swap the motor in it.

Once again... If you feel you're up for the challenge, by all means give it a shot.

And I believe the 1990 Maxima's had a VH30E in them... Don't quote me on that, I can't remember exactly. So if you want to give it a shot, go for it. I wouldn't touch the project though.

blocks are identicle inard are different from the compresion of the piston size additional horse is from the obvious dohc ( which has vvt (variable valve timing), correct me if im wrtong there), inj, and ecu. are they both either auto or std? if so you may be onto something
note auto ecu works for manual but manual ecu wont work for auto (electronic shift sellinoids)
good luck

i really have tried...i am beginning to think it is a lost cause.

i agree, i have to read it about 5 times just to slightly understand it.

[ZedEx]

... I read it about 15 times... I'm lost as well.

The blocks are identical, however the internals (inard) are different due to different pistons. This results in a different compression ratio. The difference in horsepower is obviously from the DOHC and VVT on the vg30de in the 300zx. The injectors and ecu are different too. Are the transmissions the same on both of them? If so you might be onto something. Just as a note the automatic transmission's ecu works for manual tranny cars but the manual tranny ecu's don't work for an automatic car. (Something to do with electronic shift sollenoids.) Good luck.

man my head hurts...

wow, that is amazing, i would of never been able to do that.

[zlova]

sweet, thanks for the info im just going to rebuild the z, but as for the maxima i think the aftermarket turbo will be easiest.... although i dont necessarily enjoy easy.

thanks again, its good to know that if i have trouble with the rebuild of my 1990 i will have an buttload of really smart z lovers out here to help.

the max is manual and the 300 is auto.
