I had a similar issue with the ATR45SAT with timing being limited up top. I made 289rwkw on 98, on my 25NEO. Told it was most likely exhaust, i have 3" bell mouth dump to 3" straight pipe. What brand dump/front are you running?

Please add above tech Chitchat in my thread I will reference the type of exhaust fabrications and cooler side of things to get the most out of it. And please keep this thread dyno sheets only. cheers.

Hello from Norway.

My car is a 1987 Nissan Laurel C32, probably familiar to some of you. Basically Its the sister model of the R31 Skyline.

The engine setup is as follows:

Stock internal RB25DET from a ECR33. Tomei cam ex cam gear adjusted 2 deg retarted.

Vipec Plug-in ECU,

GT3076R old type 7 blade 52 trim with AR 1.06 twin scroll T3 housing.

Homemade twinscroll manifold with single 50mm Synchronic wastegate. Divider goes all the way to the valve. 

Stock intake manifold for better low end torque than the junk Freddy manifold i had previously.

R33 GTR intercooler.

ID1000 injectors

472hp/347kw, 570Nm @ hubs in Dynapack, boost 1,45 bar. 99 RON pump fuel

get a proper PWR 600x300x89mm fmic, block bov and use a pod filter. will increase power and response by heaps.

I'd start with the cheaper options mentioned here first... my Blitz LS return flow provides 315+rwkw with better response than most RBs running similar power levels (i.e. full boost by 3300rpm) whilst providing ample cooling for hard track work.

Thought it would have made a bit more, but turbo seems to be out of puff. Thought about going up to say a 25G 10cm turbo, but the midrange and response is pretty awesome, so I don't really want to change much simply for a bigger number on paper.

All you need is to upgrade its compressor. Below is using one of our upgraded TD06-20G in 12cm using ATR43G3SAT compressor before and after upgrade.

Will be something I look at later on, Im just happy to have it back and running after 2 years building it haha.

 

Do you have any sheets for that that turbo on standard capacity 25?

 

What would a core changeout be worth?

Got a retune done on the car same setup. Turbo is still laggy until nearly 4k rpm. Made some power mid and high range.

New dyno plot
  • 2 weeks later...

Updated my result from awhile back with:

1x 3in to 3.5in exhaust, with gate plumbed back now as opposing to going to Atmo, through two mufflers.
Walbro 460 pump, with the 120psi relief valve over the 70psi one. Fuel tank lid actually sealed now too.

Different stall converter to fit the situation, which results in more slip. Added a fair amount of restrictions to the system but got a better result because of other messing around. To avoid killing the dyno this pull was WOT at 3000 RPM as opposed to stalling the converter up. So it's actually more responsive than this shows, but the dyno didn't like it.

Still have a Blitz return FMIC, so that really isn't a restriction people.

413rwkw at.. 24-25ish psi, with about 10% slip in the converter up top.
Couldn't go higher due to Splitfires starting to really call it a day at that power level, which would be higher if it had a clutch, so for anyone reading you can probably do 460kw with ~25psi of boost before they start to miss, at least in my application.

It's pretty torquey.

    • Major thread necro but how bad of a job is it to DIY? Looking at it online it looks like if you reuse your ring and pinion as long as those are in good condition it should be fine to just pull the axles/front cover and replace the diff that way? Or should I be replacing everything and doing preload measurements/gear mesh testing like the factory service manual mentions for the rear diff?
    • in my list I had the R33 GTR as the best Skyline. Infact I had all GTR's (33>34=32), the NSX, the GTO, the 300ZX, the 180SX, the S15 better than the FD RX7. I had the MR2 and the A80 as 'just' better. I also think the DC5R Integra looks better but this is an 01 onwards car. I also think the FC>FD. It's almost like aesthetics are individual! The elements @GTSBoy likes about the FD and dislikes about the 180 are inverse in my eyes. I hate the rear end of the FD and it's weird tail lights that are bulbous and remind me of early hyundai excels. They are not striking, nor iconic, nor retro cool. The GTO has supercar proportions. I maintain these look much better in person (like the NSX) especially with nice wheels and suspension which is mandatory for all cars pretty much. Some (or all) of these you have to see in person to appreciate. You can't write a car off until you see one in the flesh IMO. Like most people we probably just like/dislike cars which represent certain eras of design or design styles in general. I also think the 60's Jag E type looks HORRIBLE, literally disgusting, and the 2000GT is nothing to write home about. FWIW I don't think the Dodge Viper Gen1's have aged very well either. You can probably see where I rate bubbly coupes like the FD. I know we're straying now but the C4 and C5 absolutely murder the Viper in the looks department as time goes on, for my eyes. Wouldn't surprise me if people who love the FD, also love the MX5, Dodge Viper, Jag E Type, etc etc.
    • I used to hate R31s, and any of the other Nissans that led up to it, and any of the Toyotas with similar styling, because of the boxiness. They were, and remain, childish, simplistic, and generally awful. I appreciate R31s a lot more now, but only the JDM 2 door. The ADM 4 door (and any other 4 door, even if they are unique compared to our local one) can eat a bowl of dicks. The Aussie R31 is also forever tarnished by their association with stereotypical bong clutching Aussie R31 owners of the 90s and early 2000s. I think the Nissans of the 70s (other than 120Y/180B/200B) are far superior looking to the 80s cars. The 240K era Skylines are boss. The same is broadly true of Toyotas. Hondas don't ever register in my thinking, from any era. Mitsus are all horrid shitboxen in any era, and so also don't register. Subarus are always awful, ditto. Daihatsus and Suzukis also don't generally register. They are all invisible. I think the SW20 MR2 looks fiddly. The 3000GT/GTO is like that but way worse. Too many silly plastic barnacles and fiddly gimmicks ruined what could have been a really nice base shape. Kinda-sorta looks like a big heavy ST165 Celica coupe (and I'm not sure if that's a good thing or a bad thing). I think the 180SX is dreadfully bland. It's not bad looking. But it has no excitement to it at all. It's just a liftback coupe thing with no interest in its lines, and bad graphical elements (ie wide expanses of taillight plastic on the rear garnish). The S13 Silvia is a little better - getting closer to R32 shapes. But still....bland. S14? Nope. Don't love it. S15...a little better. Probably a lot better, actually. Benefits from not being like a shrunk in the wash R34 (where the S13 was a shrunk in the wash R32 and the S14 looked like a Pulsar or something else from the stable on Nissan mid 90s horrors). The Z32 was hot as f**k when it came out but hasn't aged as well as the A80. Keep in mind that I think the R33 is the most disgusting looking thing - and out of all the previous cars mentioned is objectively closest to my precious R32. It's just....real bad, almost everywhere you look. And that is down to the majority of what was designed in the 90s being shit. All Nissans from that era look like shit. Most other brands ditto. In that context, the FD absolutely stands out as being by far the best looking car, for reasons already discussed. Going behind the aesthetics, the suspension alone makes it better than almost any other car.  
    • If they just called it the "Mazda Tiffany", it would have been spot on.
    • Yup but for me its the HR ! Cut my teeth on the old holden 6s in the day ! And here's me thinking in the day it was also the 300ZX and the Mitsubishi GT3000 ! All, as well had good lines, but always seemed to need finishing off, style wise.
