Well since my exhaust gasket is completely screwed and leaking im going to replace the whole manifold with a custom item and finish off the rest of the exhaust!
so far i have been quoted around $500 for the custom manifold, my local mechanic is going to be doing the work, after that im going to head off the liverpool exhaust to get the rest of my exhaust finished, they quoted me the following
$300 3inch Cat $250 3inch Dump Pipe $100 Flex Joint
I dont think i have many options since i will have to drive the mx6 with no exhaust (just manifold) from my mechanic to livo exhaust and going any futher will probably attract to much attention and possibly a fine.
As Far as the turbo's concerned i still havent decided, i might be going for a VF30 IHI non ball bearing or alternatively a VF22 BB. Im only chasing around 300 - 350 horsepower so there really isnt any need for anything bigger, besides i will be testing the limits of the bottom end with that much hp esp with 160k on the clock.
im waiting on the compressor map from woo to make my final decision, hopefully ill get my hands on it soon, so far the main advantages of both turbos are listed below 
VF22
*Proven to work well with the F2T (mx6 engine) *Ball bearing, quicker spool once boost has been initiated *Better top end even if its only by a little
VF30
*Boost will start earlier due to smaller turbine *Cooler temps through-out, more efficient comp wheel (6 blades & tech) *Cheaper *Newer designed turbo
The vf30 will be much worse off boost since its non bb but hopefully the smaller turbine counters this, let me know your opinions, experiences and help me come to a conclusion

I say VF30 because BB on engine like ours with small rev range but long stroke won't be much better. As long as the VF spools in time it's fine in fact I know a T25 non ballbearing spins quicker then the stock turbo and it's more efficent. It's like a 14psi turbo is what I call it. I would like one on mine but only if it's starts to make boost above 2500rpm or it will kill my economey. I don't mind a big turbo that hit at 3000rpm because then I can drive under that and only use my bost when need. When driving don't worry about it as long is it ain't far if you get pulled overtell them and they will proberly just check by ringing up so if you can book it in or if they know they can back you up. A cop once didn't belive I was going to Australia's bes t I was in a back street near my place (of course me mate and me were just running angles )

well update guys.. i managed to score a vf22 turbo charger 2nd hand for a pretty decent price, seems in good nick to so im wrapped!
The car is currently getting th turbo put on with a custom manifold, new NGK o2 sensor along with a new exhaust system, yet to decided were to get the exhaust fitted 
im thinking 3inch dump, flex and hi-flow cat, oh and some aluminium 2.5inch intercooler piping.
Best thing of all the workshop thats doing all the work is getting a dyno in on the 30th for a trial period, free dynos to test the new setup only problem is going to be getting power to the rollers, the tyres arent in the best condition and the clutch has been screwed for 2 years now lol

MX68U how did ya get on to it? Can ya post a link to any sites on Jap importers/wreckers, cause I'm having a difficult time tracking one of these down or any 2nd hand turbo for that matter. Any body else reading too I'd appreciate the links. Thanks!

the VF series is opoular and not very easy to find second hand ring around import wreakers and importers and they will be able to tell give you an idea, most second hand turbos in yards are off factory engines unfortunatly but you still can find quite a few upgrades

Hey Oz, welcome to the site 
best place to look for second hand turbos would be the tradingpost and various online car related forums, i tried calling quite a few wreckers/imports and didnt have any luck 
Probably the cheapest and easiest way to score a vf series turbo would be around the wrx clubs/sites here in australia since they all bolt right up to the stock flange. MRT performance work on alot of WRXs and do various vf22 upgrades, etc, go check out their forums at www.mrtrally.com.au and you should be able to find a vf22/30 around the place. I found mine on an add there btw 
for a complete listing and description of the turbos download this pdf file, it has a little information on all the turbos, what models cars each vf series was on from factory and various other specs.

vf30 is actually off the newish sti's, the ones that just came out thos (03) i believe are vf34's which is the exact same housing/turbines with just a ball bearing cartridge. The vf30's you find on the pre 03 sti's are actually labelled vf35 (nfi why) but im assured they are the exact same thing 
quick run down on what i've heard, vf30 has the same compressor housing but a turbine wheel off a vf23 (boost starting lower in rpm) which a more efficient 6 blade compressor wheel giving the turbo better bottom end and mid-range response. The vf30 can also be rebuilt as its not a roller/ball bearing and provides the majority of its extra hp through its more effectively designed compressor wheel (ie heats the air less during compression).
vf22 is a larger 5 blade compressor wheel, provides a little more up top and a similiar midrange (albeit slightly less abrupt). The vf22 is a very linear turbo providing power in a very factory fashion (well at least on the 10psi i have it on ), boost comes on pretty early due to the long stroke of our 2.2 and holds till redline. the vf30 will more than likely come in a little earlier but still hold till redline happily, both i think would be great turbos for our cars, rated at around 320 (vf30) and 350 (vf22) they are pretty much pushing the limits of our f2t internals and any FWD car

there is a guy up here that sells turbo's (townsville) he mainly sells to mechanics but i could still buy 1 frome him, anyway
he reckons that the vf22 wouldn't be a gould choose for our car as we would have to change internals and shit i can't see this happening just for a turbo??

A VF22 is both on the side of Massive pwoer and perfect upgrade it can do both and will all depend on the tuning of the car to where or when it will blow up the motor.
When you try to get the most out of stock motor with upgrading the things aroudn it turbo intercooler exhaust it's then after this point that internal work may or may not need to be done. Keep the tuning right and it will live. Bad tuning it won't. I have seen a BP1,8T stokc live 3 races before dieing with a psiton blow out. but that was 23psi under race conditions all stock in a Datto 1200

yeah rods right, as long as your mixtures are correct then all you've gotta worry about is whether or not the internals can actually phisically handle the horsepower produced. As a real rough and shocking estimate i've found that most of the newer generation engines (sr20det's etc) will handle around about 80 to 100% power increase. The vf22 ihi turbo is rated at 350hp, the stock f2t produces around 145hp so yeah to use it at its full potential you should probably look into upgrading the internals. From what i've heard everyone seems to think they are fairly tough though, im really only aiming for around 300hp so vf22 is pretty much spot on for me. From what i've heard the f2t will handle that sort of horsepower assuming its all tuned and operating right, i wouldnt be too phased if it dies tho, seriously... if you modify your car to the extent of a larger custom turbo setup then really a reco and some aftermarket pistons shouldnt be too hard to live with, besides eventually you could consider that a mod, if you even manage to kill the engine with mileage |
