Decision to make

[DangerousDerek]

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.

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.

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 contacted Eann today.
He gave me some details and I can't help but get excited about this little venture. It could be epic.

Talk is now at that ' how much power do you want?' Stage.

Oh dear.

Surely that's a silly question for you Derek?

"All of it of course..."

110%

I wont say what i am hoping for in the long run. Ive jinxed this car too many times already.

Looking forward to this I think a much better idea rather than nitrous again. You can have a lot more fail safes now.

Does anyone do a steel crank for the Rover V8 ??

I would bullet proof the bottom end as much as possible and get the best heads on, because although you force in it you will still reach a restriction point as I did, and I think you will always be chasing more and more until you run 1's

500bhp for the road and 700 for the track on the proper MT tyres

Wildcat heads, Forged bottom end and Turbo - GO BIG!! (its easy to spend other peoples money lol)

Ive been offered a second hand but minimum use Garret GT4094R. Big numbers are tempting but Eann wastalking quite a bit of extra work to make it fit. At least if i stick with the GT35 we know the fit should be relatively quick and simple and will work well straight away.

Lets be realistic (i know its something not easy for some of us is it). The car will be stretched in all departments and i think 9's and 200 top end is awesome enough. I would want to build a dedicated drag slag at some point. BIG BIG power and a multilink 9" out back. Big wheelies and 8's. Any sheddy broken Cerberas about?

Who would have thought deciding on a turbo would be difficult.
No really i expected as much. Getting there.

Cheapo option is a copy GT3582 that comes from the states, has chinese parts but is built to a good standard.

Then we thought a genuine GTX3582R which ticks a lot of boxes but is pricey.

Ive been offered a GT4094R that has been used for a very short time on a scooby. We are not sure on this one and would take extra work to make fit with Eanns kit.

Turbo dynamics reckon the GT3582 is too small, agree the GTX is a good choice but recommended a Borg Warner EFR8374 at a nicely discounted price.

Maybe i need to start another poll.
