Hi people,

I tried searching for the -5 Vs -10 thread however I could not find it, this topic may be a little different as the car is running on e85.

Key considerations

- Motor is a fully built Rb 26 (26 bottom end)

- 262 in/ex cams

- Car is built for street/drag

- The car made 420 rwkws on 20 psi, we tried raising the boost however there was no power gain (I believe turbo’s were out of puff)

- Fuel system is more than capable of 500+ kws

My questions are

1. How much laggier would -10s be compared to -5s (running e85 can put more timing into it)

2. Is there an in-between turbo or any other turbo suggestions that will get me up to 500rwks?? (please keep in mind that this is a street car and needs to be low mounts)

Attached is my current dyno graph

Thanks

Daz

There you go.

Quick answer. If it's a 2.6 don't bother. It will become a nugget.

Gav made 460 + on the baby -5's. It's just a matter of setup.

Question answered, close thread ;)

For a twin set up chasing that power I wouldn't use -10s, it will just be a laggy peice of crap.. Especially on 2.6.

You probs won't make 500 on -5s but It's probs your best option if you wanna make big power on twin low mounts..

Unless you wanna run a pair of the new GTX turbos.. You should do that :)

Dan, what's involved in being the test dummy?

Someone is already interested in trying them but I could ask for a second pair maybe. Still waiting for info back to confirm the comp cover is going to fit against the standard manifold

      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.
