VF52 doesn't fit SG so I'm assuming the opposite would be true as well.

VF43 is direct fit to SG XT
VF52 to the SH XT

But I am sure one can make VF43 fit SH XT also with flange modification or correct up-pipe

I paid less than R6k for my VF43 (from 07 STI with <70000km) including headers and up-pipe.

Thanks for the info.

Had a look at the newer 2.5 turbos - the intercooler connects straight to the turbo from the top - no Y pipe so it's going to take quite a bit of modding I reckon.

1 bar is good, but try and run octane booster anyhow. NF street or sport would do.  There is a huge difference between 1 bar on pump and 1 bar with octane booster.  We even did a test on a friends 850 Volvo and without octane it made 202kw. With Nf sport it made 211kw and an extra 30nm. (same map, same boost, same dyno)

No matter how hard I try, I still don't understand how this is possible?  ???

For example, if your car is mapped for 95 octane and you use 95 octane petrol, adding octane booster will do absolutely nothing.  Octane booster don't give you any more performance, it just increases the knock index.  It allows you to run more timing (and/or leaner AFRs) and hence more power, but in this case, since you're mapped for 95, you're already at full timing so no more timing will be added by the ECU (and therefor no more power).

If the ECU pulled timing due to knock, adding octane booster will help to restore the timing and it will increase the power.  But then in this case the car wasn't properly mapped for 95 to start off with. 

This is my view.  Please correct me if I missed something.

100% correct Jacques.

One thing I've found is that not all fuels are equal, on the 86 it pulls a lot of timing on this new Shell Nitro cr@p so I'm assuming it's a case of bad fuel which the OB is then compensating for, so it's not actually making more power, it's making the power it should have in the first place. Seen the same on a buddy's car - was pulling timing on Shell, added some NF and it was back to normal very quickly.

That's my theory, correct me if I'm wrong. :D

I'm with you on Shell Nitro Sh1t, I have always put shell in, but recently I couldn't make it to a shell and I was forced to fill up with Sasol. It honestly felt as if I was driving a different car!
My average consumption went down slightly, but considering the new found power my right foot got heavier.
I'm almost considering having the car retuned by Chett but with the Sasol in this time round.

Funny you should mention that - I only use Sasol when possible.

Ran 2 tanks sasol then 2 shell and 2 sasol again under the same conditions. Could see a spike in fuel cons with shell using more.

Biggest problem is that my fuel is Company paid, in partnership with Shell. When I fill up at Shell, we get a rebate back from them, essentially just a discount off our monthly invoice, but the savings on consumption using Sasol outweigh the returns on my vehicle.

Hows them apples?
