well with those mods you can expect to run a 13.3 on little unevenly inflated 205 tyres with a 2.3 60ft and only using 4500rpm (because you have a blocked injector). This will also be around 235rwhp or so with super rich afrs in the 9's. If you decided to swap the 205's for a set of decent 255's then with a 2.0 60ft you'll be doing 12.9's.

I ran 13.4 without the S-afc or the cam gear.

The great thing about the factory setup is the potential to squeeze more responsiveness out of it. Forget the fmic to being with, when you run out of engine response based mods or you go a bigger turbo then have a look at it.

Forget the FMIC ....

Do you forget what country we live in .... and what season is round the bend next ?

I may only have a lowly silvia, but my experience in cooler upgrades shows there is great power and consistancy to be gained.

40 degree days, foot flat, no ping, chopping skylines .......... Love it

hahaha :) :)

I have read along with great interest on your many posts regarding the stock cooler but i am still un convinced this is the way to go. I must admit you have me nearly convinced every time i finish reading a post but never completely. I am not trying to start another stock cooler argument just hoping you can shed some light on a few queries.

There has been much talk of quater mile times but how do you fare mid summer after say 4-5 traffic light duels on the trot with heat soak on the factory cooler?

is there any sighn of detonation ? a problem i had on my 180sx prior to a cooler upgrade.

Have you had your car on the race track ? and if so how did it go same question as above.

Again im not trying to have a shot just curious of your feed back as you seem to like driving your car and wondering how it fared under these conditions.

A question you have probably already answered but any way how much time off your quater do think you would lose by fitting a larger cooler( have you tested this or the presure drop across the factory cooler).

If a big cooler is so much worse, why is the factory gtr cooler so much bigger? asuming that its only .1 of a litre larger in cappacity

and has 2 turbos that would significantly decrease inlet temps(only an assumption).

Again just trying to clear up some things i have wondered.As i had fantastic gains down the quater when i fitted my front mount went from 14.1 to 13.7 no other changes.(was running 14psi both times)

Beaumondt,

Your too polite :P haha

I swapped my stock cooler for a truck core. Now if people don't like truck coolers, I can tell you its better than the stock one.

I gained around 20rwhp from cooler upgrade. Admitedly a lot of that was in the piping as well. But that is part of the cooler upgrade.

Now No doubt Rev210 has done well with stock core. End of the day its one example though. I don't know where else he has spent time, on tune, timing etc .....

Its a the standard mod's that are known to work well. Cooler, Zorst, Boost. They are Best bang for buck really. There also safe mod's for people not to sure on what there doing.

Rev210, nothing wrong with the Mod path you have taken.

ITS JUST WEIRD :)

Not Wierd. Just informed.

The Factory cooler is not a wonderful unit. It is however, along with it's piping a low volume and 'short path' system. Making the actual time taken to fill the pipes again with boost that much less than some of the larger ic setups. Although it's not hard to make greater peak power, it is tricky to translate that into an equal response time. Response time = accelleration time.

The factory cooler provides a bottle neck at boost above 12psi but really the factory turbo is able to produce excellent power at this boost level, as seen in the example of Gus and his car making over the 200rwkw mark.

I think it is possible to design a better intercooler more suited to the factory turbo and retain the responsiveness. At the end of the day I like to squeeze as much out of the factory system as possible, it's cheaper that way and you know you have improved 'the system' so that when and if I swapped the intercooler the gain will be higher.

The intercooler piping on the factory silvia is an issue, on the skyline it really isn't.

      Actually, that's not entirely true. It's also the same motor in the 1st gen Nissan Cube but they're rare as hen's teeth.

      Unknown sound similar to BOV on positive boost with partial throttle RB26

      Yeah it is always worth testing and balancing actuators out of the box, just set the pressure regulator on a compressor very low (eg 5 psi) and increase it slowly to see when they both move.....unfortunately while you may be able to adjust the length of the actuator rod to minimise any difference, the actual pressure they move from is not adjustable so you need a well matched pair. And yes, the VCAM is probably contributing; the earlier in the rev range they come on boost and the slower the revs build (I think your demo was in 5th), the more you notice it.  Driving at WOT through 1st, 2nd, 3rd etc you will probably never hear it as any shuffling starts and is over super quickly

      oh they were with that motor, you need to remove the engine to change the spark plugs (don't have to, but it does make it easier)

      I certainly fall into the annoyed camp, but glad to hear that if it's happening at low boost then I'm not likely going to blow a turbo and end up with metal shards in my oil. Just feels like it prevents me from really driving it without hesitation and "peak" performance. Wonder if it's the VCAM, it did an impressive job of shifting the torque curve and faster spool, but maybe now it's "too fast" and there's too much air for how open the throttle is.  Based on some other threads, will also do some reading on synchronizing the actuators. They are the default actuators that come on the Garrett's and I would think they would be set the same coming from the factory, but if the turbos don't actually work exactly the same way at the same time as previously mentioned, it would be worth making sure the actuators are actuating together properly

      I went down this rabbit hole before, ended up sourcing a motor from the UK (I'm in Japan) which also didn't function correctly. With the original motor, I disassembled it and reassembled it and it works somewhat, sometimes. What I could deduce from all my screwing around is that there is calibration of the gears on the inside of the motor and two ramps on the main gear which activate switches that operate the motor and move the sunroof either to retract into the roof or tilt. Where I got stuck was that, it seemed in my case that one or both of the switches that are activated by the ramp on the gear did not always activate and thus the motor did not move, causing it to sometimes not retract or tilt (apologies, I've forgotten which way it didn't work.).  Of course this part is discontinued at Nissan now, it's the same part in the S15 but no other models. I also contacted the manufacturer of the component for schematics - forgot the name, they're based in Gifu - but they declined to share the information due to being bound by an NDA, sadly. Looking through my pictures now, it seems I last had a crack at this in 2022. See, I so kindly wrote "open" and "close" next to the switches. If you figure it out, please do tell me. Those little switches, with the red buttons may need to be replaced.
