my mate runs one in his evo, edmy fitted it and said it was quite straight forward on that, however i believe a subaru is a pig to set up, very impressive with a led gear indicator on the dash thow
I run a HKS sequential in my old RX7 it was the nuts, I did go the wrong way up he box once though lucky the RX7 could take the revs

Don't think I could justify the money for one again rather spend time and money on suspension setup

Been at the fettling again. Shame to butcher the Lateral headers and up pipe, but necessary.
Cut of the Lamda boss on the collector and started fettling with the die grinder to fit a 1 3/4" stub pipe to fit the Tial MVS Wastegate.
This means that once target boost has ben achieved the Wastegate gasses don't need to go up the up pipe meaning a smaller one can be used to aid spool, rather than most conventional installations where the up pipe would have to carry both.
The Lateral uppipe is deceiving in that the bore initially appears HUGE at 63mm, however there's a clever secret inside in that there is a venturi in there throttling the internal diameter down to speed the gasses up as they enter the turbo.
After tacking the tube and Wastegate flange on I bolted a spare up pipe on and the wastegate as well to stop any distortion of either flange during welding.

Learned this the hard way last weekend when making the up-pipe with KennyS and the heat bent a 12mm thick stainless flange like a Banana. Had to start again with another Flange bolted to a GT35 exhaust housing this time to keep straight and soke the heat away into the housing.


Next had to sit and fettle the inside to grind where the tube protruded inside the collector to smooth it back flush.

Had car out at Golspie ((very North Scotland) this weekend at Caithness Car Club Sprint. New suspension setup from Graeme at Whiteline and a couple of his Gucci bits added
Car felt really good, first practise was ruined, but not in a bad way by the Syvecs engine trips trying to make sure I didn't kill my engine. After tweeking that to suit the tight but long 180 deg bends there, second practise was well under the course record, so things looking good. Weather was changeable with showers rolling through, but in the end still managed to take more than half a second out of the record. No one else in the class so was just racing a time, difficult to get motivated sometimes when it's like that.
Sunday, different Circuit, Dry practice, 0.01 off record, rained like **** so second practise was well weet. First timed run was a bit compromised but by second, all was good and dry and managed to take record by half second again.
So all in all car feels great, it's fast, chassis feels good and new tyres are working well, now looking forward to Doune in two weeks !! Woo
