olivers turbo would be a decent turbo for race use age. (I am assuming thats the turbo you are talking about
) I would say if you are looking for a daily the vnt hybrids are the best because of less lag. Now the 2056 is not a bad daily rig with good amounts of tuning upgrades....
At minimum you would need new oil lines for the turbo, and a 8v exhaust manifold to t3/t4 flange. (plus a custom downpipe for the car). Olivers price isnt bad if you have fabrication skills and abillity to do it yourself.
Other suggestions I would have for this would be...
1)pp764 nozzles or larger
2)upgraded cam
3)11mm pump
4)2.5" exhaust
5)chip tune
if you didnt already know that...
6)3 bar map
7)newer intake
8)head porting
9)lift pump
10)other suspension, braking, and tranny mods not needed to mention for performance sake.
Those items should get you a healthy 190WHP and a higher rpm band. BUT a 1752 1856 hybrid will net you more power under the curve and will be much better for street useage with the same mods...
hope this helps price is good
