I've done the 20v silvertop conversion, so if you do go down that route, feel free to ask any questions.
It was a few years ago though, so wiring loom changes have long been forgotten
(I do remember someone offering a ready made loom for the conversion for a few hundred quid if you prefer to avoid the wiring).
RR power
(genuine figures, no 50bhp drivetrain losses at the RR I use) was 149bhp.
Personally, I preferred the SC to drive, but it's very much personal preference between the two
(I've driven diesels for around 9 years, so prefer lazy torque to high-revving).
I'm very much inclined to agree with Paul on the 2zz-ge.
I have an SC project sat in my garage waiting for me to do something
(anything!) with it
- were I to actually get round to picking up the project
(highly unlikely) I would almost definitely go down the 2zz-ge route, preferably forced induction as on the Exige.
Fantastic engine, lighter than the 4AGE, and really its natural successor.
It will cost you plenty more than the 20v or 4AGZE though!
