i second his notion ^

 

Spec 3+ with Aluminum Flywheel, and Spec throwout bearing, off with the spec stock stuff and on with the Sikky quick bleeder and line adapter.

 

Still waiting on the motor to get done but held up by rod bolts being out of stock. Trans still hasnt shipped from being built but they did give me a 1 1/2-2 week window of shipment

 

So, I'm not gonna read through 6 pages of this...but I do wanna say AWESOME!!!!!

You gonna make it to IA in Nashville in July?

 

you could do that with TT VQDE at a lot less weight... but V8 sound cool

 

That's an interesting question. IMHO, I think he could get that hp number with alot less stress on the LS motor vs TT VQ. And probably run the oem high compression vs a built short block on the VQ.

But I think 600-650 is just in the reach of a fully cammed, headered, intaked, tuned 7.0 427 LS motor. Stock 427 Z06s are in the 515hp range? I'd like to see the weight comparisons of a built NA LS to a VQ35 with two turbos, intercooler etc...

 

he said he planned to boost... so the weight comparo would not be LS NA... even without FI, I think it's gonna be heavier... piping doesnt weigh much and SC or turbos aren't overly heavy, even with ancillary intercooler, etc... an FI setup on a VQ isnt gonna add as much weight as this...

The weight distribution is what I feel throws off a V8 swap... for a drag car it might be okay - but imo, handling is gonna be jeopardized quite a bit.

 

If im not mistaken i coulda sworn snyper said his engine actually weighted LESS than the VQ?

 

that would be surprising...

 

Right but he also said he wanted 600-650 hp. Might not have to boost to get that.

I think the LS is heavier. No question. But everything you add, adds up. The turbos feature cast iron exhaust housings that aren't that light. The IC while pretty light is thrown out on the far front end of the car. From an informal search. I get about 315lbs for the VQ35 and 415 lbs for the LS3 (I assume fully dressed for both)

So we are talking about 100lbs difference. NA. Turbo the VQ and I guess we can roughly assume a 50lb difference. At least the turbos are down low and back. But a V8 only has 2 of it's piston sticking out further than the V6.

IMHO only here. I'd probably would rather have a very warmed over NA LS than a TT low compression VQ35 wicked up to 650hp.

It's not a question of what's better/worse. More about preference and discussion.

 

Um. No.

An LS1/2/3 maaaaaybe. But this motor is an iron block.

 

I don't think anyone said one was better or one was worse... and yes, it is a discussion about preference - that's moding in a nutshell...

 

I felt the point needed to be made. The one great thing about these LS motors is that headers, cams, intakes, tunes, heads etc.. yield some big (relatively) na gains VS NA gains for the VQ35 (even accounting for the 2 less cylinders)

 

Wow Im so anxious to see the results

 

Holy ****!!!!
