VF30 help

[STiNGR]

New to the whole subaru scene so go easy. Got a 1999 wrx wagon non sti. Just brought a VF30 for it. What is it that I will need to upgrade and look out for when putting this turbo in. The car has 440cc injectors, full system, v7 sti fuel pump, apexi pod etc etc. Also what oil should I be running? What type of performance increase am I looking at? Finally what are the pros and cons of doing this turbo upgrade??

[ADIKT]

Good turbo upgrade! i used a vf30 on my built engine.. and i was impressed!

Should be almost a straight swap i beleive...

[STiNGR]

Yer done a wee bit of research on turbos. Was going of either a vf28 vf29 or the vf30. Hardly any of these pop up for sale and when this did I grabbed it with both hands. Got it for a song I feel...$100

If u usin the stock boost controll setup and Ecu then don't worry much abt upgrading anything else

Have seen a few mates upgrade and there was a better pul from the bigger turbo and the stock Ecu still managed to keek things in check

In fact there was a article abt same upgrade by The rigoli brothers workshop in a magazine and they had a vf22 swap and things were still good

They have the video on utube abt it as wel

Was a good upgrade

[STiNGR]

Would you have a link to that video??

[Kiwi_Fozze]

sti pump should be all good, personally i'd go for a new walbro for piece of mind. only issues I think you'd have would be if you tried to wind the boost up a touch after doing it, ecu may have a right fit.

in saying that, i'd love to do a vf30 swap in my forrie, and you're right, they are bloody hard to find. good luck!!!!

You need to make sure you use vf30 bango oil feed bolts or else the factory wrx oil flow will not be enough

[1989RS]

otherwise a turbo shop can drill urs out to vf30 size

i upgraded to this turbo on my 1996 sti RA, did have the 23 on there, deffinatly think the vf30 is an upgrade. but yea 1989 rs got it, you deffinatly need the oil feeds off the vf30, the oil feed for the vf30 is HUGE compared to 22,23,24 etc haha let us know how you go.

[STiNGR]

Sweet, Wont be doing it till the new year. The car is a daily so I cant have it sitting goin nowhere, Need to put a external on 1st as it has the internal gate welded. As Im new to subaru's where coould i pick up one of them oil feed lines etc?

[Stoffa]

probably cheaper/easier to find a rear exhaust housing and use the internal wastegate, only a vf30 will fit though as a vf30 is thrust bearing.

otherwise a you can get a cheapish uppipe from STA in auckland, the M&H pipes and wastegates are ok quality for a cheap product, then you'd only need to get the wastegate vent plumbed back to your downpipe. probably still cost $400+ to do, so not such a cheap turbo after all

[RA_Jay]

its not the actual line you need to change, you just need the bolts, maybe try and post a picture of what came with your turbo and we will go from there.

[STiNGR]

I may as well just buy this. Cheap enough. Saves the pissing around trying to source bit and pieces. I will be runnig the external gate.

[RA_Jay]

yup thats what ya need. nt sure about how good the quality will be tho haha.

just drill the banjos out to 1.8mm plenty heaps for a 30.

[Pappu1]

U should get the banjo bolts with the turbo mostly

It will fit Ur stock lines so no need to buy anything extra

In any case u can get matching bolts from most Subaru workshops for cheap

has anyone mentioned these are prone to cracking the housing on the exhaust side yet?

check it carefully once you get it

True that. If you spray the inside of the exhaust housing with CRC then give it a wee while to dry, then look very carefully for hairline cracks extending outwards from the wastegate opening. The CRC will soak into the cracks and highlight them for you. Kinda like poor-mans NDT.

Really?? cause the banjo bolt that comes with the vf30 has like a 5mm hole running all the way through it.. my old vf23 had only 1 hole that was like 1.5-2mm big. defiantly dont think it would have been big enough to provide adequate oil.

[Swindog]

the hole in the banjo is different compared to the capacity of the line.

[mr.fix.it]

it was steve (vorigan) that told us the banjo would definately need drilling out at both ends

[STiNGR]

Yup! The exhaust housing has a huge crack in it! Need one ASAP. Can anyone help??

[X]

chances are that they all cracked. best to just get something like a P20 or another P18 from different VF serious and get it modify by steven from MSE to fit or give up and get a similar STI turbo

edit; sorry half asleep while writing that lastnight haha

[STiNGR]

You lost me mate? New to subaru's. Im from chch also.
