Just wondering if anyone has driven both turbos back to back and what they thought.
Had a go in a billet 7200 and there is more lag and while there is more boost it is higher up the rev range before it boosts. 7000 is gives something before it boosts fully at 3k which is nicer for traffic driven car. This billet 7200 car may need a new bypass valve as the current one it old - so when a new one is swopped in things may improve and so this could improve the car's abilities ?
For a real everyday driver short runs - I'm thinking a billet 7000 on an Iroz Motorsport SS exhaust manifold with a matching 3" downpipe, cat bypass pipes into the rest of the oem exhaust system.
Standard dual mass flywheel - drives nicer in stop-start city traffic - ditto for a Sachs oem clutch, maybe an RS2 FMIC, but probably not a reverse intake manifold as it may not be worth the grief getting it to fit.
If the engine came apart maybe rods, a balance, and a mild porting of the head to clean the castings up. RS2 airbox.
Anyone any experience of this spec ?
It wouldn't need any more than 330hp tbh.
Thanks for any comments.

And if was doing it again, he'd probably go for a new style turbo as the extra expense of a new turbo would be worth it over sourcing a reconditioning a used K7400. Hindsight is a wonderful thing. Hopefully this thread saves somebody from going down the 'wrong' route.
I know, what am I doing on here I hear you ask and why do you own those S cars? - so leaving that comment aside for the following reasons one wanted to retain early boost but have more poke than a fry could provide and therefore decided on a small'ish modern turbo which would limit the power curve, and to counteract this lower power curve and also setting aside the additional money required and the last reason of as one liked the idea of a IROZ SS exhaust manifold and matching 3" inch downpipe, would they be 'worth it' from a power / torque / driveability point of view, or would it be better to just leave the existing oem manifold or maybe a Wagner cast manifold and an oem downpipe and run a little bit more boost ?
