just a thought.
i know there are kits available for the gen 2 but curious to know what the negatives would be on turbo for gen 2.
from early reading when i purchased my gen 2 the rwhp was less than a gen 1. would this be due to the higher comp ratio in the gen 2?
what modifications would be needed to a say a gen 1 turbo kit.
would you go for lower comp pistons or can you get away with spacer?
would i be better off with a gen 1 and turbo vs gen 2 turbo. i know there is a lot more proven data on the gen 1 as they've had more development time.
Based on resale a turbo will sell easier than a big bore kit and with more hp available via more boost etc i'm thinking this may be a project for after the drag season.
keen to see how horndog goes with his gen 1 but value for dollars it could well be a turbo for me in the future. still getting used to the bike.
thanks for reading and all feedback appreciated.

Oh the pressure
I cant wait to see how my turbo build goes either. Once I get my licence and tech inspect finalised hopefully I can tell you.
There is no strong performance without a little fanaticism in the performer
i would love to see a turboed gen 2

Issues with gen 2 compared to gen 1 are the comp ratio being higher limits the boost you can run, also the Titanium valves don't like the heat as much as the old valves , and lighter valve springs (because of the Ti valves) need replacing art lower boost levels than you may get away with on a gen 1
A simple low boost kit like RCC or Velocity would bolt on and if tuned right be good for low boost like 4-5 wheras a 02-07 may be ok to 8 psi (and lots have burnt them at lower levels than this due to incorrect tune or poor fuel)
If i were to build one on a limited budget i would decompress with a spacer,fit a set of head studs and nuts,and put a RCC kit on, and run around 8 psi on pumpfuel , that should get you around 70-80hp increase.
RCC are upgradable now the base turbo has a greater potential than previous, if you decide to step up to higher boost levels or upgrade to secondary injectors you don't need to change the whole kit.
engine would need to fit gen 1 or stainless valves and some better springs.at a higher level

so Maj if one was to decompress, put stainless valves and hd valve springs into an 08 motor it should therefore be able to handle a decent amount of boost and power? which i imagine should be a little more than a gen1 as from what ive heard the gen 2 rods and pistons are a bit stronger? or is that just crap that people have been saying with out basis

oh and one more question if i was to get a stage one kit and decompress and put new valves and springs in could i safely run that setup on low boost to comute on? if i was to get two maps done?
Regards

I would think for similar mods the gen 1 and gen 2 would handle similar boost levels and the gen 2 would make more hp due to its capacity increase.gen 2 just has to be treated a little more carefully in std trim.
I like low boost, unless your bike is modified with a longer swingarm or lowered ,first is much more friendly on low boost then stage it up from there. ....boost levels don't dictate how commutable your bike is, that the job of the right wrist , riding in traffic may take you from a to b and not actually see any positive pressure .

very helpful maj. the gen 2 should not have any injector issues with 2 of them per cyclinder and supposedly good for 450hp from the forums. 240hp at the rear or even 250 would be more than fun and yet rideable.
the valves is something to look at as well for big bore gen 2's. dollar for dollar a gen 2 with a turbo sounds pretty sweet although i reckon i could sell the gen 2 and get a gen 1 and fit a stage 2 kit for the similar coin which sounds very tempting.
will have to see how horndog goes before any decisions made. nothing like pressure hey Matt.

There common in the US now, if you shop around could probably find a low mile second hand one or buy new if you want security of knowing you have a complete kit with support from the seller.

Jamie Have you considered using the ecu reflash to totally run the 08 turbo ?
very nice now there are boost compensation tables and a plugin 3 bar sensor option for the std ecu .
