Nick: This is why I added in a real world street driven car ie: a daily driver that rarely see's the top end the Roots is simply stunning! :) Way too many downsides to be a viable alternative without some serious engineering time spent on it. The Shop that does my Axles makes a Screw type so...

Koulee: Of course the Turbo takes power to make power....... Otherwise it would be a perpetual motion machine and the World would be run on turbo motors.... it's just not as easily measured as a Blower for power consumption.

No Supra = Banned ;)

10 psi should be fine the 7M is pig rich in stock tune so this will give a safe tune as long as the rest of the parts are in good order!

In a purely street car a Roots style Blower wins hands down for daily type driving instant power. With a modern BB Turbo this gap is much smaller though. Centrifugal SC's I have to ask "Why?" they have the downsides of both the Roots and the Turbo and just don't make a lot of sense.

If the Cams are still in some of the Valves will be full open this is normal. I wouldn't be running a shim in a 7M it's hard enough to get our motors to seal correctly without adding another potential failure point. At a guess I'd say 3/4 of the 7M's out there are running in your...

1/2" mild steel will work fine as it gives a little extra to surface once you're done welding. (Stainless would be nicer but it's a little harder to work and more expensive)

Stock is 1.37mm thick, you've had .5mm removed it's not the end of the world and will bump the compression up a bit and move your cam timing a touch but not enough to really affect things badly.

Eric: There should be a "Hot" and "Cold" mark on the tank.

Repair/replace radiator Flush cooling system refill with either premix coolant or distilled water and coolant concentrate Burp cooling system check it daily for a week or so and top up as needed with coolant.

LOL either jack it up or park it on a hill Idle it with the cap off and the heater on full Keep topping it up until no more bubbles come out then bring the revs up a little top it off and cap it. It can take a bit of time to get all the air out, I check the level each day for a...

Sounds like a guttfull of Air Eric!

Good Vid Aaron can barely see the tow cable ;) (Mk3's don't move under their own power) <jk>

It does ;)!

You can retorque in 100 miles it's not so much the distance but getting a few heat cycles into it! Drive it daily to operating temp then shut it down over night next day repeat do this 3>4 times and you're good to go on the reTq!

Sponsor maybe ;)

For sure! I couldn't find one so got the SSAC 321 stainless one and it's almost 3mm wall thickness so is quiet for a tubular (my exhaust is quieter than stock so a noisy header would piss me off) :)

Eric: It's more noticable on thinwall headers they "ring" like hitting a bell! It's not too bad on turbo cars but NA's it can be really annoying! ;) Cast headers are much quieter! (most modded Mk3's run noisy exhausts so you never really hear it)

Cast iron headers don't "ring" like tubulars do! If I'd been able to find one at the time it would have been my first choice!

I was taught this when I first started working on cars and it's 100% correct! :)
