why the thread below on swaping a vq into a 3rd gen was closed?

 

I dunno, but I wanted to reply to it meself..

I doubt if it would be possible, to be honest. you gotta worry about the ECU, tranny, mounting, etc etc etc.
plus the guy was talking about SC'ing the VQ. for several $k cheaper, he could turbo or SC his own engine (forget whether it was a VG or VE), and have just as much power WITHOUT the hassle of trying to figure out an engine swap and cram a rhino inside a gnat's ***.

albeit, I think it would absolutely kick **** if it could be done. talk about one hell of a custom job!

 

advantages.
First is weight. The vq is definatly lighter than the VG. If i rember the 95 add correctly something like 150-200 lbs. That change alone would bring the car to near sub 3000lb range with driver.

Second: Power. Ok in theory the VG can take more power than a VQ, but is that power going to be usable? Scing a VQ give you more low end grunt and more than adaquate top end. I also think that there is a lot more potential to be had out of a VQ people:1 just havn't shared or 2: havnt spent the $$. Now there is a turbo version of the VQ direct injection over in japan, so it can take the higer stress of turbos. I guess how much is the real question.

Probelms.
1. Getting the damn thing to fit w/ wiring harnes etc.
2. the #of parts that would have to be replaced in the front end to get power to the ground.
3. I've noticed that the VQ sits closer to the firewall than a VQ. So actual mounting might create a few probelms.
4. How would the suspension react to having 200 less pounds over the front wheels.
5. cost- unless you hapen to find a max that was rear ended that you can buy cheap, i don't know how feasable it would be. On the other hand it would be pretty interesting.

This also brings up the theoretical question about stroking a VQ with a VG crank (see SCC august? editorials) I'd like to try this if i had the chance. Stroke it to 3.4L and drop the compression to 9:1 w/ 1-1.5 bar of boost Granted the quick reving supersmooth properties might be lost, but WTF!!!!!!

The VG crank was already disproven I think. But that would be an interesting swap. I wanted to do this last year before my old car died, but the shop that was interested had just sold the crated VQ they had, I think it was Place Racing. Now they just do fabrication.

I've also talked to Scott @ Overboost, and he seemed to think working up the VE would be more doable than the VQ swap. I'll see in a few months when I have a VE Max for him to play with.....

 

Who cares? VQ's suck!

 

But why waste time and money on a VQ swap? Sure its lighter than a VE or VG30DE is but there is ahole lot more fabrication. For one thing the VQ uses 3 engine mounts and 2 tranny mounts. Then you have to swap wiring harness and ECU in addition to the entire VQ powertrain. This means you need everything from engine to CV Joints to the front hubs, control arms, etc. IMHO the VE is a very good engine to modify. The cams are teh same as the VG30DE, VTC operation is the same (minus more overlap with VTC's on in the VE) which is more bias for lowend torque. Also the SC for the 4th gen doesn't even start to build boost till around 2600 with 6psi pulley, and with 7.5psi pulley it builds at 1500. A ball bearing T4 or T3/T4 turbo would build boost around 2000-2200. Did I mention the VE's bottom is as strong as the VG30DE's is (both are the same). If there was enough room you could use VG30DETT manifolds and run twin T25 turbos. As for running the oil and coolant line for the turbo it won't be a problem since the VE has the same blind plugs as the VG does. If figure if your going to do an engine swap do a VG30ET or VE30DE with turbo. Also keep in mind that the fuel system and ECU must be upgraded to support over 210FWHP. Besides the VQ doesn't come with a LSD tranny in the US.

 

What a coincidence. Me, Matt, and LordRandall were talking about running twin t-25s in instant messanger chat last night

 

Shhhhh! You'll blow the secret!
