I was wondering, why didn't you just have your old engine rebuilt with forged pistons, stronger rods etc. so you would have a super-powered E6, rather than just buying a new RS engine? I think this would have been more cost effective eh?
Not the shaft - the turbine wheel material thats different.
Wheels are normally friction welded (I think?) to steel shaft.
Anyway - Ti is lighter - less inertia therefore spools up faster.
Also Ti is more heat resistant (I think?) - better suited to high temperatures of anti-lag systems.
I went for the new engine mainly for peace of mind and for the speed at which I could my car back on the road.
Looking back I could have waited and got the engine rebuilt but...
a) There was no specialist nearby me that I had confidence in rebuilding an engine properly and transporting the engine and possibly the car etc. would be a pain in the arse!
b) I needed the car back on the road ASAP as it is my only means of regular transport and rebuilding would take a lot longer.
c) I did ask about getting a second hand engine but the garage didn't hold much hope of getting one soon and you never know the history of a S/H unit.
d) I am never convinced that a rebuilt engine is as a good as a new engine reliability wise.
There were a few other reasons aswell and believe me I weighed them all up. At the end of the day I went for the easiest and quickest route to get my car back on the road however the easiest is never the most cost effective.
I would like to say thanks again to all those that offered support while my car was off road. If I didn't get around to replying to everyones emails then I am sorry but I was inundated with help!
I am glad there are so many helpful people out there!
True about all the helpful people on this board! http://www.ltregister.f9.co.uk/graphics/happy1.gif border|EQU| 0 align|EQU| absmiddle >
BTW, I also got my car finally sorted out. The loud booming sound / vibration was being caused by the camshaft not being properly aligned with the balancer and crankshafts! [img]http://www.ltregister.f9.co.uk/graphics/sad1.gif border|EQU| 0 align|EQU| absmiddle >
My mechanic says its a good thing I didn't use the car hard when it had that problem, which surfaced after my engine rebuild. I guess I won't be letting that shop which did my rebuild work on my engine anymore. [img]http://www.ltregister.f9.co.uk/graphics/sad1.gif border|EQU| 0 align|EQU| absmiddle >
I think the only difference is the Ti. Compressor Wheel vs the Al. alloy one
where the Ti last longer, lighter weight which spools up the Turbo faster..
As i know the difference between RS and GSR is the vehicle body reinforcement and lighter weight with no luxurys stuff in it (i.e Air-Con, power windows)
Actually i believe the RS models from the factory come with a lighter steel body, no air con, no recaro's (only regular seats),ordinary wheels and brake system. the reason for this being that these cars are built for competition and it's easier for the buyer to strip in order to replace with competition parts. also, the gear ratio's are closer and of course the titanium turbo. i think both GSR and RS TM Editions have this same turbo.
In Spain Evo V comes with no Recaro seats, no air-con.,no electric windows.They are made for rallies.I have fitted the Recaros,the air-con.and turbo meter kit as options.
We can choose the gear ratio and between the small and big brake kit.
Evo VI and Mak edition are avaiable for rally use or with all fittings.Ralliart Spain says that both have the titanium turbo,Evos VI Mak.Rs and grs(rs2 in Spain).
Botchi ,you got a Evo 4 RS right?Did you do some aftermarket rear wing and 17 EVO 5 OZ wheel on your car? I saw a very nice looking white Evo 4 RS with the DTM look wing on Alabang Total gas station about a week ago in the evening ! when I was driving around there.Will it happened to be you??
