Take everything you hear about pulse with a serious grain of salt, and go have a beer with damobboss if you are serious and want to talk about it. If you're planning spending 10k on an engine whats 200 bucks in flights to go get some gossip from the horses mouth and not some internet forum. Im sure he has good and bad things to say, and there are great parts and shit parts of his TT convo. And im sure he'd happily explain those and some of the costs involved just to scare you shitless.
A turbo EZ30R done right is an absolute weapon. Lazy 330+kw atw with 18lbs on a gt40 that isnt even on its compressor map yet.
Turboing an EZ30R done cheap:
The stock motor is not made for boost, or even remotely close to it. Anyone who says otherwise is full of shit.
But if you must do it, it can be done relatively cheaply.
Budget the purchase price of the engine (a confirmed runner 3.0 with no big end knock...haha about 2.5+ grand as a minimum. I have spares).
A computer to run the engine (Vipec V88) $2500
Even the cheapest of manifolds using the stock 3:1 merge, to a twin scroll T4 flange: Maybe $1k
Turbo GT3540r, GT3788R, GT40R $1.5 to 2k
Wastegates: $600
Intercooler: 200
Stainless or alloy plumbing $1k
Modify fuel rail to parallel with returns, add a decent fuel pump and a new lift pump, and a larger feed line, and 6x sti pink injectors: $2-3k.
Full exhaust inc cats off turbo w/ wastegate merges? $2k
General fabrication (oil and water, cutting out shit to fit crap, removing the engine a half dozen times to get little fiddly bits done etc. $2-3k
Clutch/flywheel: $1600 from jim berry mates rates. Add 20%
Full 6 speed conversion with brembos F&R and R180 rear diff, R180 shafts and machined rear hubs to fit, with a set of R180 spindle carriers: $7k or so.
Dyno time and tune: 1500-2k
Now factor in the things I havnt thought of. Add x %.
All of this is a waste of time with a stock block. Factor in a rebuild with pistons, rods, bearings. Block preparation, head preparation, new ancilleries, valve springs etc. $somewhere well north of 6 grand as a minimum.
Looking at a reliable, safe, engineerable car. Somewhere around 350kw atw. And thats doing it all on the cheap.
Ok so now we have established that this is a stupid option.
You have a 2004 liberty.
2008 impreza sti twin scroll half cut $8000
Fitment and bullshit as a drive in drive out conversion $5k?
Still seems silly...
Sell 2004 liberty, buy an 03+ sti.
