Sorry if this is a repost but I thought it was interesting...

I've never heard of a vq35 swap before. I would rather have an LS1 in their if I had to go pistons but still cool!

The VQ is an overall better engine than an LS1.

In what regard?

Room left over in the engine bay?

I believe GM showed the world what motor was better with the ZR1 vs GTR.

SKarpenz

Amen. The LS motors are superior in every aspect to the VQ.

1fastlatino

agree'd the ls1 is tried tested and true theres almost nothing as far as performance that cannot be attained with an LS1

Sketch_hs

vq35 is junk!

ls1 is far superior at making power, despite how low tech it might be.

it would probably a lot cheaper to swap.. and the vq35 is extremly reliable.. those can be some pros to it for those considering it.. i would just prefer it for the sound :P i hate borring v8 engines they sound like crap... personal preference

haha...good one pal!

I hate to say this but the ZR1 doesn't have a LS1 it has a LS9 6.2liter supercharged V8, the older ZO6 had LS7's. In the debate of GTR vs. ZR1 I have seen test going both ways & besides you are comparing a boosted V8 the LS9 against the VQ35DE V6. the comparison should be either the LS9 swap against the VQ38DETT swap or the basic LS1 against the basic VQ35DE. Both are amazing motors one a V6 & one a V8 which resond to mods very well. It comes down to where do you want your power & what do you want out of the car?

the ls1-ls9 are all very similar, the ls9 is just basically a supercharged ls3. Yes both are amazing motors but the vq35de does not respond well to mods as i remember, just about the only thing you can do to them is turbo/supercharge without going into the engine since they are so maxed out from the factory(basically not much potential without a huge amount of money).

rotordad

Of course the LS1 & LS9 are similar & with any motor when achieving high numbers you have to go into it. On one hand you have a V8 & the other a V6, I have a few friends with 350Z's & they are doing fine around 500 hp without spending a fortune. The LS1 would be the the best bang for the buck but if you are talking LS9 ha ha ha might as well get a Built Cosworth VQ shortblock or do the 4.2 stroker with boost & blow away that LS9. LS9 around 20k with 630hp. A LS1 with a 150 shot would be a very nice combo in a FC & cost shouldn't be all that bad.

yea thats usually what the v8 guys do, just spray the hell out of it. for the vq guys wat all did they have to do to get to 500? I know all the basic bolt-ons dont do anything for them (full exhaust, cai)

rotordad

^ LOL they wish just some bolt ons got them there. Each one is running a different turbo set up, but all of them have custom intake mani's or running the plenum spacer, all of them except one is running the new plug & play Haltech, exhaust & cams ect.

BASEDLS7RX7

would an ls9 even fit an fd, didn't Chevrolet have to raise the hood on the zr1

the VQ engines are good at making power with simple boltons... they got vq35de engines making 400whp in japan.. and these arent full blown race cars either, they are customer cars that Z enthusiasts take to tuning shops to get 400whp naturally aspirated too btw.

but im not trying to be biased or anything... cause i honestly would rather have an ls1 over a vq35 too because its a v8.

but the vq engines still have my respect for their power potential..

Stock rods can only handle 400tq. waste of time with the vq35, unless you start upgrading internals.

My stock block VQ made 430whp for years at 9lbs of boost (single turbo). Thats as far as I was willing to push it, as the rods are the weak piece of the puzzle around that hp level.

I put new pistons, rods, and ARP bolts in, went with a twin turbo kit, and on pump gas made 650whp. Race gas was able to increase to high 700's with relatively small twin turbos (greddy 18g).

To me, thats a pretty nice engine. The LS1 would need to be built to make the same amount of power (reliably for extended use). They are both great engines. The LS1 is higher displacement, and therefore is at an advantage, there is no replacement for displacement. haha. But the VQ is a very efficient and reliable powerplant.

supergoji

if you are talking about the DE and rev-up motor's. the HR is an entirely different story, much more power no problem.

and 316hp Naturally aspirated stock.

not to mention it loves boost and it's head flow rate is great and on the HR motors the heads get cooled first which is a bonus.

the VQ35HR and VQ37VHR guys are making anywheres from 400-500whp on pump and 600whp on race on the stock engines reliably. some people have blown their motors but there will always be a few.

VQ sounds like a race car ls1 sounds like someone's exhaust fell off lol.

TheGloriousTachikoma

There's another consideration in the VQ's favor that no-one has listed, Weight. I thought the point of these cars was the great balance and handling, and especially on a NA rotary, the extra weight of the V8, even if it's aluminum, upsets that balance. I imagine the VQ would be around...20% lighter than a LSX, no? And shorter too, which would further work to keep weight towards the rear.

no the VQ isn't much li9ghter than the LS. I havent weighed my VQ but I know my LS1/t56 pullout with fluids is barely 800lbs. The Vq is a good motor and I daily mine but the saying is very true, best bang for $ is the LS fabily of motors. If you have a nissan motor sitting around go for it, if not dont waste your money./

oh, and this is a really old thread.

ssonsk

lol^^
vq sound so awesome, and they're suppper cheap now. I'd rather do a VQ swap over a Ls1 if VQ swaps were cheap to do like Ls1 :L
