Vq30det options?

[ganma_ca]

Ok S13vq30det guy, or anyone else that knows... What are the transmission options for this engine? I did a little bit of research and I know most of these engines if not all came from the factory with automatics. Anyone know if any 5 speeds/6 speeds bolt up to them? And also how is the fitment in your S13??? If you have it in? Any special mods to the engine mounts (aside from new ones) and how are the clearences? Shame these engines are so rare, I just thought it would be a good swap because there are counterparts here in the us that you can use to repair them if you need too. Thanks for any info! (oh yeah and how hard is i to wire into the S13???)

People have been bolting up the 350z 6-speed, guessing with using a 350z flywheel and clutch kit. I've seen builds with VQs and the engine fitment looks good, but noone has done the stock exhaust and turbo yet with the vq30det. I've seen one install that the exhaust was redone for a top mount turbo. Most people mod their crossmember for mounts. The wiring will be a bear from what I gather. Search for vq and s13 theres a few threads on this board, and theres a vq in a s14 out on another forum.

Wouldnt mind knowing any additional information, as i'm attempting to put a VQ30det+t into my S12.

I was going to use a 350z 6MT for ease of fabrication.

Shame on the wiring, I wish it would be a little easier some times! But thanks for the info on the 350z 6 speed, that's great info to know. (as much as I was dreading the thought of an automatic again). I think it is one of the most ideal swaps. Semi-cheap but a lot of work, but you get a turbo 3.0 with lots of torque and hp and it can be done for $2,000 or under (engine for $1,000, and transmission for $1,000) which I see some of these guys paying $3,000 for just their S14/15 SR's. (i also mean without the labor included weather you diy or pay a shop, I'd rather do it myself). I'm sure some of the maxima guys could shed some light on what the wiring would be, enough to wire them up for an S12/13/14 etc. I heard about the turbo/dp fitment wasn't great unless you did swap them out. I'm going to try to search for some pics on which manifold to get and if the top mount is the best way to go for fitment issues.

Wiring will be fun to say the least. On the vq35de you need a body control module, the nissan anti theft antenna with a key, and the drive by wire electric gas pedal.

But there might be a way not to need all that and run it on a JWT retuned maxima ecu. The vq30det does not have the variable valve timing.

As for semi cheap i'd say you will spend more on the vq. there is the engine, the 6-speed, modifications to the engine crossmember, modifications to the shifter assembly, modifications to the transmission crossmember, custom driveshaft, custom y-pipe and headers for NA or custom headers and downpipe for turbo, a high flow fuel pump, then the wiring.

The SR is made to bolt in and has lots of parts available, but to get near the stock vq power levels will require upgrades.

[ganma_ca]

AH I guess I meant over all for better power for less $$. That's true there is a lot more work involved in the VQ swap Vs. the drop in SR, but i'm sure the SR would never match the torque or hp of the VQ for cheaper. Just because of the sheer displacement advantage, even if you did a stroker and ended with the 2.2 SR. Plus it would nice to be running something different then all the rest of the bandwagon. I mean aside from the obvious items, I'm sure there are plenty of parts that cross over to the vq30det from their counterparts here. I might write JWT and ask them about the retuned ecu to combat those issues. That would be great if it was something they could deal with. I wonder how it effects the over-all balance of the car as well. Thanks for keeping us updated, and for the good info. Kraelic

Plz do this. I've been hunting down info on VQ30DET's and getting pretty much no where...

It seems to me, that for who ever has their heart set on a VQ35DE swap... The VQ30DET could be done easier for around the same price and it seems like an all around better motor to me...

If anyone in the U.S. has completed this swap, plz post up. Cuz I haven't found one yet...

Also, I've heard that the Pathfinder 6spd transmission is a better choice for this or any VQ/240 swap because the shifter has more optimal placement and the gearing is similar to that of a stock 240. I dunno if it's true, though.

I thought only the 09 pathfinder v6 came with a 6 speed? Might make it a bit expensive or hard to find a used box compared to a 04 onwards 350z box. FYI from doing a bit of research it seems it was the pre 2004 350z boxes that had a few issues but all were fixed for the 2004 manufactured boxes onwards so if your after a 6 speed make sure its out of a 2004 manufacture date onwards 350z.

You have to make sue the 350Z 6MT you get is not the VQHR. They have a different lower half and the bell housing is different.

The 4.0 Pathfinder i think has the same HR gearbox with the same ratio's. It's the diff that made the difference.

The VQ30det has the same flywheel bolt pattern as the VQ30de's which from memory is different to the VQ35de's.

I just cant find the spec's comprehencively anywhere :s
