5% sounds healthy for an engine with those miles, maybe it has been torn down? I would honestly be careful running that level with stock rods and bolts/studs, it's going to be high 400's with that turbo, maybe even 500fwhp with 1.0bar.
Brian will point you in the right direction for the fuel head mod, it seams you'll have everything you need, other than being sure you won't snap a rod bolt..... And maybe a slightly better cam profile to really make everything breathe...

I'd make sure you have a rock solid bottom end first, you don't need to split the case to do rod bolts, and fit ARP head studs while it's torn down..... Sounds like a lot of work, but when you have a con rod sticking out of the crank case you'll wish you had, and running a GT35r at 1.0bar will be pushing things...... The fueling is a must to get right, check out StuP's thread on balancing the fuel to each cylinder, you need that 'absolutely' spot on
