Tires, brakes and suspension play most important role in cars.
Doesn't matter if it's Fj, VG, KA, or SR etc if these arent right it won't be
fun to drive.
The only reason I wouldn't put a VG/ VQ in a 510 is the fact that
it's a PITA to work on.
Some Boost in my FJ is good....More is better!!! :D

I would think in straight line accel and 1/2 the VG would have the advantage but top end would go to the SR. The Vg has copious amounts of torque but revs out fast, the SR will pull right up 7500 maybe more with the setups listed.

Watch the vid of VGwagon VS my KA wagon... I get tooled off the line but once at speed things start to lvl out.

LOL, funniest thing I've heard. My VG is so easy to work on in my 510, only the oil filter is a pain in the ass.

You know, I have to put a comment in here. Normally I stay neutral in such matters - run what you brung.

I'm a a guy who loves the sound on inline 4's and sixes with a wide open induction set up => ITB's N/A'd. But I'll tell ya - Denis's VG wagon has a scream to be envied. You would need to hear it to really appreciate it, but it's something else and it makes his car awesome in its own right. I never liked the VG conversions until I got to know Denis car.

Thanks Byron!

Funny thing is I changed the muffler and now it sounds much different....still searching for that nice sound but remain somewhat quiet inside the cabin.....I don't like how it sounds still.....search has not ended.....might just have to buck up for a Borla.

No doubt, The VG has it hands down in the sound department. I was in the Broadway tunnel in San Francisco and behind me I heard a ratted out 350 open it up. My god that thing sounded seriously pissed off as it flew by me. I was in my work truck, but I had to excursive every once of impulse control I could muster not to punch the gas and chase after. Tools and all. :twisted: Even with a stainless steel straight pipe an SR wouldn't even come close. :cry:

I have a friend or 2 with large turbo's on single cam vg's and they all say the same thing. High horse power vg's with big turbo's tend to munch rod bearing's .

I was a little biased toward sr's since I have one 30 miles to the gallon 246 horses in a 510 what's not to love. But then I went for a ride in my buddys z31 (vg30et) with a holset running 22 pounds of boost . Holly crap that thing got up and moved and the torque was insane. But every 4 to 6 moths he smokes a rod bearing and is now going. With a ls and the car has sat for the last year. I drove my sr to canby and got 30 miles to the gallon on the freeway the other Sunday.

.
These cars were built to withstand the neck-breaking torque of a 1300cc or 1600cc, struggling to get near 90hp

The lightweight construction's strength relies on the chassis' abitlity to flex and bend.. There is no frame, or defining structural piece, it's merely a myriad of spot welds, held together by quantum theory .. :lol: .... I've feared for my life numerous times driving a 510 with a L16, not only the semi truck tires higher than my roof, but a L16 will get you into plenty trouble. Luckily when my car did spin out of control, the L16 was perfectly balanced for the 510, and somewhat predictable in a 360 spin ... :lol:

What keeps you out of the ditch is your steering wheel,,, .. even a L20b is too much weight to avoid over-steer,, I can't imagine even more weight



Do these look like the frame rails of a 500hp sports car?: ...... :lol:

Frame rails. Damn, do I have to be a spelling and grammar Nazi here too!? ;) jk. Ratsun is down, I'm very disappointed.

I'm sorry, all I heard was blah blah blah blah Datsun! :D I miss Canby already. And Ratsun is still down. Having withdrawals. And contemplating the next motor for the 510. I was seriously considering a VQ, but the cost is a little off-putting. The VG however is a dime a dozen. Hell I saw a whole truck VG on craigslist for $100 today. Probably needs a rebuild, but that's easy enough.

However, I also have a Z22 in the garage that I'd like to run. Could turbo that I suppose. Or the other thought is using a KA head. But I already have a new custom EFI manifold for the U60 head. Been itching to run that and the Datsun guru that built it wants to see the performance. Air horns are built into the runners. He had to build a whole new tool to do that. It's pretty bitchin'. Almost thinking of trying to make the big hp the hard way with the 2.2, just for the cool factor.

Still, it's odd the VG almost seems to fit better than the 4 cylinders. Took a lot of pictures of the engine bays of various cars at Canby. Lots of VG, and seems to be for good reason, and a boat load of torque from the extra displacement.

The KAZ22 would have a disappointing compression ratio I afraid.
