Help me decide.
I am gettting a good deal on wild cat heads on my latest engine build. Need to decide on whether to stay NA with ITBs and direct port nitrous or retain a standard(ish) inlet and go turbo. I plan a few thousand miles on the road next year. What do we reckon?
The NA option should yield over 400 bhp.
The turbo option could be over 500 easily.

Hmmm.... nearly posted the other day when you mentioned the wild cat heads and N/A, was simply wondering why go to all that trouble when the turbo is such a 'simple' and cost effective solution..
I know I've said this before so apologies for being repetitive, but next step for beastie had to be ITB's, it didn't stack up to turbo or SC a lump with 10.6/1 CR... but at over 3k a pop for an ITB set up and possibly only another 20bhp from them I simply couldn't justify it..
Turbo gets my vote Derek...

I voted Turbo...
But the truth is... nothing, and I mean nothing! beats a large capacity normally aspirated engine.
To that end Derek, can you add a 6.3 litre LS3 option to the vote please?
That Cerbera I drove with a LS in it was insanity itself, but what really amazed me was how much of a pussycat it was when you just wanted to pootle about.
Big torque is good, but how it's delivered is everything

What compression ratio will you have? For big fun safely I'd suggest 8:1 with a turbo or two. I think that's going to be safer then a big 'hit' of nitrous. You'll need an expensive clutch to go with it. If you keep the tvr plenum you can modify it to accept twin charge coolers. It's good you have a deal on the table. If not I'd have suggested the Ls option.
ETA, will the rover inlets match the wildcat heads?

The bottom end is built.
ACR remanufactured block with toughened offset ground crank, Chevy rods and forged pistons with floating pins and spring locks. 7.5 thou deck height and 22cc bowl including cut outs.
The wild cat heads are new bare castings yet to be CNC ported and the chambers have tons of meat so we can set the CR there.

Of your two choices, turbo has to be the answer on the strip, as it will give you the option of more power than NA, and you simply don't need to use the turbo on the pubic road.
But having been for a ride in Quinny's LS Grief, my vote is for an LS engine. Loads of torque and bhp, pussycat in town, smooth tickover, decent mpg, wonderful rumble.

I like the way you guys are considering my needs when making the vote. A couple years ago I would have been tempted to go SC. A part if me would love to build an all out drag car with a proper old school blower out the bonnet.
But after seeing a few recent and very successful turbo installs I think it will serve me best.
Going to aim for 500bhp as a starting point.

I love this technical terminology stuff, Phil in particular is a master of it 
And I've noticed over the years that worryingly his words usually involve something sperm related
This being one of my particular favorites...
