-9 response with -5 grunt you mean.

That might be a challenge too far. But would certainly rock the boat.

[CEF33Y]

That sucks about the engine damage, no way should you have worn the cost!

Oh and I'm surely a minority, but would love to see you spend a bit of time on the RB20.

[Badgaz]

i'm building an rb30 at the moment as well...i already have an atr43ss2 which is what i'll initially be running on it....hoping it should make more power earlier.

Rb25det owners are the back bone of this community as well as my workshop. I've purchased a better conditioned R34, it is fully stock, and I will be modifying it all over again. It is a good opportunity for members whom might have missed my previous build and hate to dig out pages.

I will sum up lists of parts I'm ordering and label prices and shop names.

For members inquiries about the Rb26dett, Using unopened engine, I don't think its possible to get much better response using the simultaneous twin system. For a single high mount, I can get you pretty close to the -9's response while getting -5's power.

For RB30det engines, It varies, I'm getting all sort of engine CPRs depending on whom its built by. Generally using a Rb25det head and a NA VL 3L Bottom you end up some thing like 8.3:1. You can use our ATR45, ATR45SAT or ATR45SS on those to get very good response and decent power output. I'm keen on Rb30det results also, PM if you need a turbo for it, I'll be more then happy to trade discount for results.

Stao, you're a f**king legend. That's all I really have to say.

3. JJR's stainless steel R34 3inches turbo back exhaust system: $770 - package includes ceramic cat- wouldn't this be an issue?

[hypergear]

And No issue.

[iruvyouskyrine]

Stao dos you ever see my RB30/SS2 results? I posted them up here but never got any response from you.

[hypergear]

Yes I do remember seeing it. Pretty good result for the level of boost given. Want to go larger?

[zebra]

why chase 400kw with a pos exhaust?

get something decent under there

[jay-rod]

A 3 inch JJR exhaust is perfectly fine.
A bit of die grinding on the dump flange and its perfect.( if using standard 6 bolt )

[XKLABA]

It's really simple to test, run it up at 400 then drop exhaust at cat and run again

I would have thought a 3.5" at 400 will be better then 3"

[Badgaz]

Yeah agreed 3.5in for sure.

[Piggaz]

A 3 inch JJR exhaust is perfectly fine.

3 inch for 400? Errr...

Golf ball and garden hose.

[Ben C34]

400 is the new 300

[GTSBoy]

To be fair, most aiming for 400 are probably doing it with E85 and might be able to squeak it in on a 3". Maybe.

[Piggaz]

Why make if any harder than it has to? Just put an appropriate sized exhaust on it and everything will be happier.

[Artic Choc]

^^ exactly.. im going for a 3.5" exhaust for my goal of 400+kw, imo just makes it easier to achieve and more reliable
