You can use an innomach shim like I used to. Get a .060" one for around $80. You'll blow the engine with a 125 wet or dry and turbocharging it on stock internals. No nitrous you can push it over 500 with a shim and turbocharged. The downfall is sealing the timing cover is extremely hard due the shim and it wears on the chain tensioner noticeably after 10k miles
