VF18 and VF27 work on TT?


Bobby

Recommended Posts

Hi All,

 

Firstly TT Legacy's are a pain in the arse. 

Secondly I cannot find a VF26 in Auckland.

I only have a VF27, so I would like to know if I could replace my VF19 with the VF27?

Will the VF27 work with a VF18?

 

I was going to do a single turbo conversion - but to be honest most workshops were asking for 7k upwards - not including a Link ECU. This made it uneconomical.

Pretty sure an old member here had luck swapping a vf27 guts into the 26 housing. Not sure exactly what was involved but he was a bit of a backyard hack so can’t imagine there was any machining involved.

 

Edit: pretty sure I misunderstood exactly what you have. 

Are you saying you have a stuffed VF19?

Not sure if a 27 core will fit what you’ve got in that case

Im a bit confused, sorry.

Are you running a vf26/19 combo?

 

I can't find it at the moment but I found a thread on another Subaru site that had a list for turbo swaps on a tt engine. But from what I can remember there's no big issues with going to a bigger secondary turbo.

so a vf18/27 should work.

you have a BG5 GTB yeah?

 

(more details = better answers)

 

So did I

 

I went from a 18/19 to a 33/27 odd pair or something like that, ye it worked hardest part was the change in turbo inlet size that meant different intake runner from the air box & such

 

pretty much same turbo's otherwise just newer

I actually have a 96 BD5 RSB with the ej20r motor in it. The engine has 255000km on it.

The turbos are definitely labelled vf18 and vf19.

The car just suddenly overheated at the back of Carbine road in Mt Wellington about 1year ago.

Apparently it was a split hose somewhere, but it did enough damage to the head gasket on cylinder 3 on the exhaust valve side.

I didn’t fix the car at the time as I saw a black S401 come up for sale on trademe and went and brought it.

I originally wanted to single turbo the car, so I have all the components, like a rebuilt greddy td06 20g, fmic, exhaust manifold, twisted turbo pipes and ej207 short block. 

But paying a workshop to do the install is quite expensive, about 9k and over which does include a link ecu and tune. 

The car itself is a beater and cost me 1400.00 originally so I lost the desire to spend so much on.

 

Anyway skip 1year later and I have taken it to our local mechanic Drury Auto Services, to give it a birthday and fix the head gasket. The engine is out now, and the heads are machined, new steel head gasket, the new vf27 turbo replacing the vf19 turbo, the eBay twin turbo silicone intake, radiator being checked over, new thermostat and a Mines ECU. I have got a 240km/h instrument cluster, 18inch Legacy sti wheels and window tints to finish it off. It will just be a run about car for my parents business and family.

 

in the meantime I purchased a second hand closed deck block only from e&h and I am going to rebuild it into a short deck block by myself as a learning exercise. I am a novice so it will be interesting rebuilding an engine myself as I have always paid workshops to do it.

 

I am looking for the right GC8 Type R car to eventually put one of the motors in.

Bad news from Drury Auto Services today. 

The ej20r block is warped.

 

So now I am not sure what to do.

I took down a brand new EJ207 short block I purchased in January, and we are checking to see if it will fit? 

 

Any advice?

Hi All,

 

Just a quick update, almost everything has been put back together. 

We are just trying to source a plug for the EJ207 Short block oil breather pipe. Apparently this oil breather line would connect to the intake manifold.

However the Legacy RSB does not have this.

 

One question a split fuel rail system would this work on my 96 Legacy RSB? I was thinking of purchasing this:

Any advice?

I will put pictures up soon.

      Afternoon team,
      im new to the group first time posting. Im hoping some body can help me get my launch control all dialled in on my link g4x. Ive had the computer and car all tuned from chris at prestige awesome knowlegable guy super happy with the results but now im wanting to get my launch/anti lag all dialled in. Ive been reading multiple different forums etc all with different conflicking information which has made me nervious with what do i listen to this or that if you get what i mean. Now ive started to make myself familiar with my PClink software etc the past few weeks and im eager to learn how to do minor setups or tweaks etc so im not relieing on my tuner so much and obviously saving myself abit hurt in the back pocket. 
      Now back to the question at hand.... Im wondering if theres and one who could please share there knowledge and wisdom with setting all my values, timing, fuel etc when i have launch control armed and engaged, or even a launch tune file they can possibly send me to load onto my tune. Ive figured out the setup of my digital inputs turning launch control on etc and its obvisously on its pre set factory settings. It engages but doesnt sound the greatest or as angry as it should i feel. Hence reaching out to you good buggers. 
       
      Cheers in advance for any info and help yous maybe able to give me.
       
      Cheers Shaun
