Even better (I didn't realize he had the car on a dyno dynamics with the -7 set up)...

164rwkw @ 4500rpm

205rwkw @ 4500rpm

From other graphs on dyno dynamics his set up does look down by 40odd rwkw at 4500rpm but that still does not cover the 100hp it has improved with the 35R

Here's a decent -7 result, more boost could've been used but stayed conservative (98 BP PULP);

This is a silly comparison anyway, a 35R is designed to make more power than 7's ever will so of course its going to seem lazy and have a bigger top end. Anyone who doesn't understand that should give up modifying cars right now.

But the previous dyno graph shows the 35R has more response and more top end over the -7s??

Do you have the 35R one in RPM vs boost?

i know it may sound like a "how long is a piece of string" question but how much boost would you run on a healthy standard internal rb26 with -7's? im currently at 19psi @ 296rwkw, thought 20ish psi is the safe limit? and you cant run much more then 21-22psi? on pump fuel ofcoarse...

You mean the one where we know the setup wasn't running properly?

Your "decent" -7 set up is making 25rwkw more at 4500rpm that the one that "wasn't running properly". Funnily enough the GT35R makes 74rwkw more at the same rpm...

Yeah great - so that's agreed

Maybe i've missed something here (and it's looking that way), but explain please how you got 74rwkw difference between the two at the same rpm - I simply cant see where the numbers come from for this 35R.

At 4500 the -7's are making around 210hp (157kw) and the GT35R is making around 320hp (239kw), so it's actually more like 82kw.

No idea about boost vs RPM, it's snozzle's graph so maybe ask him :)

Ah ok now I see where.

Lets compare that 35R result vs the one I put up then, the 35R is close enough to 239kw and the 7's are close enough to 230kw.

So for a bolt on set of turbos, vs new oil and/or water lines, dump pipe, exhaust manifold, intake piping, turbo to FMIC piping etc, with a goal of 300 odd rwkw (remembering which thread this is), the 7's win on cost while they come in an ever so slight second place to power in midrange.

A 35R will go so much further power wise than the goal of this thread, so IMO for 300 odd rwkw throw a set of 7's on at 23/24psi and with the other basic supporting mods the owner is there.

EDIT: Checking my last graph, i'm at a touch over 260rwkw at 4500rpm with the EBC turned off. Hooray for low end :)

I would be going a 3076R for 300rwkw and you would only need 19psi :) They are so much better than a GT35R!

Plus I think you will find the cost comparison would be fairly similar, how much do you think it would cost from filter to cat to get the twins going?

Checking my last graph I'm at around 270rwkw at 4500rpm with 500cc less that you :P

are the -9s really that much better then the -7s?

If you only want 300kw, then the extra $400 for the -9s is a waste of money. If you want to go past 320kw, then they're the right choice.

are the -9s really that much better then the -7s?

I've had both, I prefer -9s over -7s. Some say it may make no difference but if I were to buying another turbos I'd go for -9s.

ive checked the specs on -9s and -7s and they're identical apart from the comp wheel & trim.

so for example if at 19psi, the -7s will make 290kw, what will the -9s make on the same boost?

is the -9s the same response as the -7 or slightly laggier?

    • Just wanted to pop in an update on my setup. The CD swap has been great, I love the mazworks housing for the overall simplicity. I ended up sealing my trans tunnel with a thin sheet of aluminum reused some of the holes on the trans tunnel, and laid some window sealing EPS foam around the edges. Works great, really quieted things down and sealed up the car.  As for the power comment. Right now I am also running about 650whp. with the way the bell housing is attached to the face of the transmission I have zero doubts it would be fine, mainly because the input shaft and main shaft bearings are seated into the bell housing adapter. This means the load is NOT on the bolts to maintain the power, rather into he casing of the bell housing; Yes the bolts are doing some work there, but with both shafts locked in zero worries.  End of the day, the Mazworks solution is the easiest and safest. no need to take your trans to a shop to get milled perfectly, it fits with minimal clearancing, and you can use all your existing clutch and flywheel.  Driving wise the CD has been great compared to the big box, I'll probably swap my final drive at some point. The serial 9 shifter is gooooood, my only qualm is how tight it is, it takes a fair bit to get use to, 5th and 6th are a bit eh/hard to find at times, but maybe I need re-adjusting, and I think my clutch master is very tired and needs a rebuild. 
    • If you are keen, have a look at my build thread. Car is for sale for the right money or straight swap for a F80 M3 LCI.
    • Welcome mate.  No point in over thinking it, buying any one of those cars you mentioned is not a smart or logical choice with the availability of many "better" (re price to performance) cars available to you.  The heart wants what the heart wants, buy whatever it leads you too.
    • Hey everyone! Im so grateful to be apart of this community and ill do my best to be apart of this. Firstly, i'm not disclosing my real name due to in real life circumstances surrounding my privacy and public image (sorry lol) Secondly, The only thing personal I am willing to share is that I'm from Sydney and a descendant of one of Sydneys largest mortgage firms. I got gifted my first ever car, a 2022 Porsche Cayenne and I love it to death. Ive been driving it for about 5 or 6 months now and honestly Im so grateful for my parents for gifting me this vehicle. However recently I've been working my ass off to afford my second car (which I need help deciding soooooo community help me out please?). Once decided, im planning to try modify it myself. Recent I've been thinking about getting a Skyline, particularly a 25GT or GT-V, yes I know overrated as hell, but I'm also considering a Chaser which I recently came to love. However my dream is to one day own a 180SX (So hard to find clean versions and im not really into importing).  Lastly before I send this off, I want to apologize if I sound tacky or pretentious. I try not to and want to genuinely learn from everyone and anyone. (Im no expert in this area) Thanks for reading!
