VQ30DE in a 3rd gen?
#4
Im about to start a swap of my own and want some info. I have a running donor car that was rear-ended(a 95 se 5-spd). I have all the parts to make this work but Im just trying to figure out the best way to do this, If anyone can give me some USEFUL info please feel free to post it up.
Oh yeah, btw this is going into a 92 se 5-spd

Think about it. Different generation. You have to swap out the whole wiring system.
I havn't done it, I'm looking into doing the same as soon I get a donor.
Their are a couple recent ppl with vq's, but they don't know crap about it first hand. They had a shop do it. Not to say it's wrong to have a shop do it. But they didn't do it themselves....

You didn't say why you wanted to do this swap.
If it is just for HP, then it would be a lot easier and more elegant to put a turbo on the existing motor, SOHC even, it matters not with a blower.
The thought of having to change the computer system, wiring harness, etc etc etc and will the gen 3 axles fit the gen 4 trannie, and so on and so forth? I suppose if this is a labour of love, you can do anything...

Also the motor/tranny have only 60,000 miles
for the axles I will try to use 4th gen inner spline and 3rd gen outer...if for some reason the cv joint ends up being different...I know a shop that can make them for me for around $150
This engine is also more reliable and does not have problems with lifter or timing noise. And even if something did happen to this engine, they are very easy to find and cheap as well

the guy that had done used an AE 5th gen engine mated to a 4th gen trans. he used the 4th gen wiring and computer. i dont see it being difficult so long as you can get each wire to swap over properly. no one has thought about just using the 4th gen suspension(front knuckle, strut). i think its pretty much bolt on, and alot easier than having to rebuild axles. that's what i'll do when i try to do it

GL with the project, ignore the flamers, look at my sig and you'll see I have first hand experiance too lol.

Found out that the VQ actually has more tq than the VE at 205 ftlbs

I was thinking of doing the exact opposite!!! I have a 93 with 80000 miles and new VTCs. Only drove it a week after the VTCs, then rolled it end for end. I now have the chance to buy a 96 GLE with bad timing chain. Car stopped running. Now wont start.
Wanna Trade engines!?!?!? I can't find a nice enough 93 for the engine. Mine was literally flawless!!!

The only problems with the swap will be axles fitment and mounts. Just look at the differences in the engine bays, and weld or drill and tap it so that the 95 crossmember or whatever it has works. Wiring is not a problem, just swap over everything...good luck. This is a lot cheaper than boosting, and is a major leap in feasable 3rd gen swaps, as hopefully after completion, you can share with us your first-hand knowledge...

I've raced a friends perfect running stock 98'SE auto with my worn stock VE 5spd, and because of my poor manual skills at the time, he actually hung with me till my 3rd gear. Once come 3rd, he lost by at least 2 car lengths. But after all that, I drove both cars(5spd), and I can see and feel the difference. Before looking at hp/tq numbers, I would look at how both engines are built.

I think the cars/engines are very comparable. The VE might be just a little better with basic bolt ons, but when you completely mod an N/A VQ30, it's faster. A 4th gen 5-speed with an MEVI and JWT (along with y and intake) will outrun a VE 5-speed with the same bolt ons. Go ahead and look at the 1/4 mile times in the racing forum. There are a lot of 4th gens in the low to mid 14s and the best VEs, other than that freak Aaron are all in the upper 14s.
There are several NW guys that have run at the track on the same days and I have the fastest N/A car, but I have a few more mods than the others. I think the 4th gen guys all had intakes and y-pipes at least.
Another nice thing about the VQ (aside from no VTC problems) is you can get a bolt on supercharger for it.
If I were to do a swap into a 3rd gen, I would definitely look to tilley and his hybrid 3.5L swap that is being done into the 4th gens now.
Since it looks like terry is getting all of these donor parts on the cheap, I would just do the best you can and get everything together, then maybe save up for a supercharger.

Yeah, I love my VE but I have moved on to other things here recently(03 jetta Gli....in process of swapping a r32 motor in it...should be around 300 N/A hp) but I have thought about coming back to build a sick max...been thinking maybe VQ swap in 3rd gen....standalone ecu, huge turbo..prob. GT40R, maybe a 30 shot as well like Hal did on his, and just see what happens VQ's are so available...might as well blow em up, right? no sense spending tons of money on a motor with forged bottom end and then worry about what happens to it.
Anyone happen to know what is lighter 3rd or 4th gen?

I plan on taking the engine+tranny out tonight after I get off work, so Ill have an update tommorrow

I know I saw hal weigh his 4th at 2840lbs but was this right?

3001lbs 4th gen
3129lbs 3rd gen

3300-144=3156. And yes, the cobra rotors/18" Z wheels will make a measurable difference.

With a friend (170lbs) and I (180lbs) it weighed 3650.

Ill put them up tommorrow!!
Oh yeah, that is with intake and y-pipe
