Not as yet I only received it this week! I plan to put it on in December as I have a few other parts I need to collect to upgrade the fuel side of things at the same time

I'll take some photo's when i'm doing it all if you would like :)

Hi all!   I've not really been active on this forum for some time and although I lurk in to read bits and pieces of interest I don't really think of this as a forum I'm part of but I once was and I di

Haha - yeah it could use some more boost Simon..  I'm sorry I've not put up Motec logs in the past for those who've wanted to see. Back at the time I did a bit of comparing because I did more or

mr skidz, your posts are coming off as trolling at this point.  do EFR people go into precision threads and talk about how great their mates setup is, but wont give any details??  whilst complaining t

I'm interested to see how they added the VQ35 hydraulic cam actuator to the front of the camshaft and got it all to work.

My VQ25 runs an electric clutch CV arrangement instead, which may be easier to retrofit as it doesn't need the hydraulic lines. I always wondered why HKS went the external oil feed path... If you could post pics in a Vcam thread I would appreciate it.

Should be a great addition, but I hope you have the valve clearance. Those actuators can advance 50 degrees. Who will be tuning it?

Oh sorry I thought you meant about the turbo install.

I actually bought the car with the vcam already installed. It's currently running the the vcam controller and an fcon v pro which i'll be keeping for the time being.

Will be retuned on e85 with the new setup and will more than likely be done by tunehouse (fairly limited when it comes to tuners that can tune an fcon and vcam)

It will be more responsive and make more power. Everywhere. A guy on NS put a 6758 (bigger) on his SR and it was a bit like a V8 in terms of delivery.

Wait for the 7163, that might be a game changer.

If I got the 6258 and a manifold to suit, would would I have to convert the rear housing to a t3, or is it feasible to run a t25 housing on an rb? i.e. too much of a bottleneck not enough room etc.

No it will be fine. The best thing to do will be to have a good fabricator cut off the T2 flange and weld on a nicely shaped reducer and a T3 flange.

The housing is stainless so you can weld on a stainless T3 flange no hassle.

Read the last 5 pages of this thread as we have been discussing exactly this (i want a T3 7163).

Also, is go a bit larger and get the 6758 or 7163 as the 20s like to rev :-)

New turbine/housing options listed on match bot too.

Also found an awesome read on mixed flow turbine wheels with a mention of the pros/cons of using TiAl - http://www.hindawi.com/journals/ijrm/2012/589720/

Needless to say, I'm very excited about the 7163 in 0.80 twin scroll (although I hope the 0.80 comes out for my 7064 because I'm not changing turbos any time soon)

      Its a 2002 vr-x four VQ25DET, silver. Coil overs, lowered, polished alloys and sport exhaust. Bit of a project, was sitting in a shed for a while but runs and drives great.

      I wasn’t able to replicate the sound anymore. It was a one time sound so maybe it was just coincidence but it was like small pebbles being dropped in a coke can.   should I try cleaning the MAF? It could be it’s functioning but dirty? I don’t know.

      Update 4: Hi all. The car drives again! Haven't driven for long, only to store it in the garage again, but the test drive was successful. The coolant and oil leaks seem to be fixed for now. Temps on the engine were also very good, while moving I never even saw 80C water during the approx. 30 minute drive. Ate up all the coolant in the reservoir though so will have to fill that even more when I go to the car next time. One thing that pisses me off is that the RPM gauge is still f**ked, I even resoldered the board twice and used copper paste on the silly screws that are used as connections. Next time I take it out I'll take apart the board and fit new components, I'll see if I can get a replacement IC for it.  I have an appointment set for 22nd of September for the engine tune to 370hp. Alignment also still needs to be done. My hope is that I can get all the legal stuff over with by the end of this season. Anyone of you have advice regarding intercoolers? Currently there is an APEXI core fitted, one of those weird hybrid ones, 600x270x76. I don't think it's bad but it's not new and now I still have the chance to change it now to legally include it in the paperwork. Only issue is that the only options that would arrive in time are a HKS Type R intercooler or generic Ebay spec intercoolers comparable to a JustJap one. Ideally I'd order a Plazmaman but it takes over a month to receive which would mean making the car legal has to wait until next season. Would love to hear some input on this. Same story for my injectors, the previous owner was a nunce and put ID 1050x on the engine. They work but are obviously not ideal at "normal" power levels. But I don't see a reason to change them unless the tuner says it's necessary. I read online before buying a different exhaust that the top secret style rear diffusers won't fit due to the size of the rear resonators. My buddy and I made it work by slightly "adjusting the shape" of the mounting bracket and making some spacers out of 3d print for the mounting bolts. Fits like a charm. Just putting this here in case someone has this problem. Even the hefty HKS Silent Hi Power rear can fits without hitting anything.
