2G Advice wanted for engine spec on street car build... (comp ratio, cams, lifters etc...)

[Dave_UK]

First thing's first.... I have spent a fair bit of time scrolling through all of the various threads etc looking for information and have got a lot of useful help. Sadly, a lot of the links are broken now so I am going to have to ask fresh...

I'm in the process of spec'ing up and ordering parts for my 4G63 build. Being in the UK, there is little to no reliable info available at the end of the phone. Yes we do (to a limited extent) get the Galant and Evo 1-3 but even people willing to work & tune on those are rare and hard to come by. If I had gone for a later Evo4+ then the world would have been my oyster for info and parts but it is what it is.... I'm hoping a few of you guys who have been doing this for years might be able to share some insight...

I am looking for circa 350hp (flywheel), to be street useable and not blow a transmission every couple of months. So far I have a couple of bolt on mods in my shopping basket, Forced performance exhaust manifold and Magnus Inlet but now the real tech stuff happens...

• Comp ratio... Over here in the UK we have full access to 97ron fuel and even 99 in most places. For a motor with a good slug of low down torque that picks up real quick i'm leaning towards 9.0:1 compression ratio... Thoughts?
• Turbo sizing... Plenty of access to Turbos from Garret, TurboSmart etc... what sort of compressor and exhaust sizes should I be looking for to achieve my fast spooling goal?
• Cam shafts... Worth changing for a different profile? I have read on here most people seem to switch to Kelford cams & on their site only list cam shafts that use solid lifters... Do I need a solid lifter profile for my goal? I had in mind a mild increase in lift and duration with a nice pair of adjustable pulleys... Any thoughts on accompanying valve springs as well?

The engine itself will be treated to ARP everything, a balance shaft delete, Calico coated ACL big ends, mains and thrust washers and looked after by a Link ECU system that swaps out the MAF for MAP. Anything else I should be looking out for / any handy tips or pointers on parts to buy....

No wrong answers here guys... bombard me with your knowledge!

You can get 350hp with less $ but I like your parts!

This sounds interesting, where does one purchase such a turbo?

I should have a spare evo3 16g in the garage if you're interested. I'm not sure if extremepsi or other vendors ship to the UK, but I'd be willing to.
