Hey guys got a problem my car didn't make the power I think it should have made.

Rb25det s1

Gt3076r .63 rear

High mount manifold

50mm wast gate with 14psi spring

800cc injectors

Bosh 044 fuel pump

Turbo smart fpr

Upgraded coil packs

Greddy copy intake.

3inch straight exhaust

Blitz dual solenoid boost controller

Microtech Lt12

I only made 296rwhp was the best run of the day at 18 psi

Seems low compared to others iv seen on this site?

Also I did notice that boost drops off from 18 nearly back to 14 at the top. Fuel and air sitting on about 11.6 . Any thoughts?

You will need a stiffer spring in the gate imo, and the .63 rear won't be helping things.

Can you get us some pics of your setup? Was the exhaust dropped on the dyno?

I didn't get the chart as I was not happy with the tune. Tuning was done at Godzilla motor sport. On his dynonamics awd dyno

and tell them to send you the tune file

I have a feeling the tune was shit house, also because it's a microtech lt12.. they're so clunky to tune with.. 2x tables to do essentially a single table can do.

I'll ask him to email it to me. Marks pretty good tuner. I mean it is a microguess lt12...

We had to pull some timing cuz she was pinging on boost. He said he thinks the .63 housing is to small

Not sure it's just a stainless manifold with gate mounted to it. The power I Made is not much better then a standard rb with a tune..

If you had bought a decent standalone and left the FFP, stainless manifold, fpr, boost controller etc off the list, you will have had more money to spend on finding the issue on the dyno.

    • 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!
