ive got a VL turbo on my r33 and NO it does not bolt straight up.

the oil line is completly different. I had to custom make the oil line from the turbo to the block and use the r33's return oil line.

The water lines need to be heated and bent into different directions also.

if you look at the pic where the oil goes into there is a plate with 2 bolts that bolt onto the turbo. R33 or R32 did not use this as they just banjo connectors.

Its not a direct bolt on. but would go well once installed.

if you look above its only the turbine housing of the vl, not the centre cartidge. The hole you are talking about has been tapped and takes a banjo fitting, does not use a flange fitting (you can actually see the banjo bolt in the hole). but well spotted anyway. I can tell you for sure the standard rb20 lines all connect straight up and I can also tell you they are the same as an rb25.

cheers

Have you had surge problems with this turbo?? You cannot have a Vtrim compressor boost 15psi before 4100rpm on a RB25 without causing surge.

[haste]

runs fine, no surge. thats sounds crazy to me, wouldn't surge be dependent on the turbine and compressor combination and not just the compressor?

I have exactly th esame turbo on ma RB20DETits very laggy considerring i have stock computer and coller so im not sure by changing computer ill get rid of the lag or not? by the way my shit mechanic (which is now bankrupted) didnt desine the exhaust pipe like urs with that litle extra hose he just closed it i think and its just not as good... wen i rev it up to 7-7500 RPM it feels like the boost is finishing and its just gives me the shits..

So good luck with the sell Pal...

Vtrim is a big Compressor, as long as it "Doesn't" make 15psi before 4100rpm on and RB25 it won't surge. It flows so much damn air the Rb25's just don't want all that air at low revs. My Hybrid has a Vtrim and as you can see it makes massive amounts of flow at low boost.....imagine if I could run 1.3 bar.... Mine needs and external gate for more boost.

[haste]

I don't think its the compressor, there are plenty of rb25's out there that have larger compressors etc... I think you'll find its the match between the tubine and the compressor. If you have a VG30 turbine, then that is most likely your problem. The turbine is around 42mm and the 13b turbine is around 52mm, flows a lot more. There was absolutly no surge on my car, and I doubt very much that it would surge on a 25.

MRPREZ,

It is a little laggy, but I got used to it pretty quick. Increasing timing before the turbo comes on song, will make it spool a little quicker (more exhaust gas). My turbo pulls all the way to red line.

[BOOSTD]

Ok what I'm saying is directly from the compressor map, The Vtrim CANNOT be allowed to flow 15psi before 4100rpm or it WILL surge on an RB25. My VG30 has a 54mm turbine outlet..and still has slight surge.

Haste

Can you tell me HOW to get rid of it plz?? Uhh by the way.... im getting an EMS computer done soon so i hope that reduces lagg little bit for me...

[haste]

Prez, sent you a pm

Boostd, I don't agree with you and I am going to leave it at that so I dont start a shit fight, but next time I think you stay out of people's posts.

turbo is sold.

[BOOSTD]

Sorry dude,

have done 50+ hours of experimenting and design with this compressor. If you understood what I was saying, then you wouldn't worry, if the turbine is matched then it will come on boost around 4100rpm and all will be good. As I said b4 this compressor flows ship tins of air at lowish boost which is great news for chasing big power from an RB25 without having the need to do a head gasket. I was just trying to point out that it would be unrealistic to think this turbo will spool-up super fast as it is just not possible. I think the buyers who own an RB25 would benifit from this information as you have had no experience with this turbo on an RB25. A HKS 3037 on a friends car has made 257rwkw with external gate. Mine with Vtrim 266rwkw and less boost. I cannot think of any other compressor that performs so well. For the money I will go the Hybrid hands down. Hope this clarifies. =)

for interest sake i have the same turbo but have used the original r33 rb25 intake housing because of the larger housing. which im guessing will once again make it spool up later. should give a slight increase in power output i would think.

[haste]

wonderful, do you have a v trim t04 wheel mattyb? what turbine do you have? what power are you making?
