a correctly sized turbo will produce the torque, i'd not build it from the 997,then a 1098 will not offer much more over a well build 998 turbo.
I'd use the 998 a+ block, 295 head, mpi or sw5 cam,+40 mega pistons,
if possible mpi gearset,or 1275gt/innocenti one, 3.2 diff, and a small turbo like ihi rhf3, td03, kkk k14 from an 1.5/1.7 turbo diesel, (I would look for an opel 1.7 td one).
to keep things clean, I also would like a custon made exaust manifold, or simply base it on metro/cooper spi one, and blow thru twin38's.

Take the 12G295 and fit that on an A+ 998. If the 12G295 has not been skimmed, you will have about 9:1 compression ratio.



Having done this for a car I use every day, I would suggest it's the best option. 45mpg 16.2 1/4 mile and drives like a normal car. I even use a verto clutch so it's easy on the left foot. The only issue I've ever had is carb icing.

This is what I was originally thinking, based on yours Wil.
What carb though?

Paul

I seriously doubt it!

STD metro turbo carb i would have thought.

If something is worth doing, it's worth doing half of.

don't throw out twin's idea, in a mk1, they'll be the littl etrick that'll have an edge over..sure you'll make a nice airtight alloy airbox looking like a genuine one

Emember although it's a 998 it'll be producing 80 to 90 bhp in mild form, so a 1 3/4 carb is well sized.

know that,
but Paul's work being from Mars,
sure he could sort a stupefiant set up with two little twins, a pitot tube is really nice to tune,you can rip the restrictor with his ugly plenum, and even use a set of ram pipes,
just pushing him to make something special, Back'p me!

TBH the thought had crossed my mind as it has twin 1 1/4" on ATM and they do look great but an HIF 44 usually out performs twins on anything uptp 100 bananas in my experience
