Hey people, I bought a skyline with a lot of mods but have yet to get it dyno'd so i have no idea what kw's its putting out.

I've listed what its had done and hopefully some1 can tell me possibly what power it could be putting out and any estimated times likes 0-100 km/h, quarter mile. I know nothings rock solid till I get papers to prove. Im after a sheer estimate.

The car is:

r33 GTS25T 95' Series I

GTR Front Mount Intercooler

GTR Fuel Pump

T3/T4 Highflowed VL Turbo

Apexi S-AFCII *yet to be tuned at Croyden 'Racing Emotion' will get Dyno before and after*

GReddy Profec B Boost Controller

Blitz Dual Turbo Timer

3" Exhaust

High Flow Cat

MegaFlow Muffler Twin 2" Tip

Pod Filter

Blitz Open-Atmosphere BOV

Brass Button Clutch

Locked Dif

Light Racing Rims

9.5" Wide Rear Tires

Lowerd 3" Inch *Estimated*

Strut Brace

Always run Optimax 98 Octane.

Stock ECU *Yes, PowerFC soon, Autronic would be nicer*

Max Boost 10psi because of Stocko ECU.

I'll have to get it on strips soon. Have to get 3-point belt first right?

Anyway anyone who has similar mods and any times, or readings would be great.

Cheers:run:

JimX, can you please explain why you dont agree that the Autronic is not nicer then the PowerFc

uh, oh ... i can see another ECU debate brewing ;)

Depending how the SAFCII goes with the static ignition timing i think you will make about 220rwkws with more to come with the management sorted...provided your T3/4 is a good thing

I didn't say the Autronic wasn't a better ECU. I was looking at his mods which are very mild, and wondering why he thinks an ECU geared up for racing cars would be "nicer". I'm not sure, but doesn't it ditch your climate control along with many other aftermarket ECUs such as Motec? This could have been something they've fixed, but I seem to remember way in the past reading that it didn't support the Skyline's climate control.

For a mild car, all I can see in an Autronic would be a higher initial purchase cost, higher tuning costs, a limited number of tuners that could do it, and potentially no more climate control. "Better" argument aside, I still can't see how it is "nicer".

Ahhhh great estimates, thanks.

I have done 0-100 in 6.01 with 1 passenger at 10psi, granny shifting with a stop watch.

I was a little disappointed with that thinking i would get into the 5's possibly a little easier. I would have to get into Mid 5's if i was running 10psi, No passengers, and Double Clutching. You can really feel the difference even with one passenger.

As for Quarter Mile. I did a street quarter mile at an approx 13 sec with 1 passenger, 10psi, granny shifting. I believe i'd get into mid to low 12's if no passengers, double clutch.

One Last Question. If I got my new ECU and say boosted to 14 - 16 psi. What type of rwkw and Quartermile times could i get then. Would we be talking about low 12's, high 11's would be nice. The difference between 7 and 10 psi is huge. That extra 3 psi gives me 20km/h higher speed in 2nd gear. So if i had another 4 - 6 pound. I'd imagine it'd really start flying then.

Yeh good point, I wouldnt get a Autronic for 2 reasons in my situation. 1. The price. 2. I'd have no use for my T Timer or Boost controller no more. Autronic handles all that. Its funn adding parts here and there to your car. There's a place i seen who said they'd do an Autronic for me for like $3000 or something, they great mechanics, but I'd just go the PowerFC coz all up you can buy 1, have it installed and tuned for around $1600. I never knew that about Climate Control? Surely the new models wouldnt have that problem, anyway who cares, i aint getting one.

Thats odd, as the top speed in each gear is restricted by the rev limit, unless you were shifting earlier, and changing boost wont change your rev limited

As for Quarter Mile. I did a street quarter mile at an approx 13 sec with 1 passenger, 10psi, granny shifting. I believe i'd get into mid to low 12's if no passengers, double clutch.

You should go a lot faster if you dont double clutch, you only need to double clutch a non-syncro gearbox, like an old truck or something.. meaning push the clutch in, let it out when its in neatural and blip the throttle, push the clutch back in and finish the gear change...

hahaha u think u would run quicker 0-100 times if u were double clutching?????

I think u mean flat shifting????

double clutching? wtf? i think you've been watching a little too much fast and the furiNAWS.

vin diesel's granny shifting speech was full of crap and didn't make sense... oooh..

Hmmm Ok. Firstly Yeh. I usually run standard 7 psi. Which gives me 80km/h in 2nd at around 6500 rpm. when i use boost controller and put it up to 10psi, i can do 100km/h in 2nd gear at same rpm 6500

As for doubleclutching. Have you even tried it? It really kicks you in to the back of your seat surges the car forward. The difference between 'flat' shifting and double clutchin in 3rd and above makes quite a difference. Certainly gets you do the next gear quicker.

This thread is great!

Must be all that "double clutching" which is changing your gear ratios on the fly dude!

Correct if im wrong...double clutching is depressing clutch entering neutral releasing clutch...get the sybnchros moving then depress clutch and enter gear...gas on..?

Thats not what u do in a drag...u just quick shift or flat shift

Yes Vin Diesel what you were told to say in the script is WRONG.

Please explain to us what you think double clutching is????

Dude the car does Nkm/h at Xrpm regardless. You will not change this without changing the gear ratios in the gearbox or the diff.

      Unpeeling the Orange

      Update 3: Hi all It's been a while. Quite a lot of things happened in the meantime, among other things the car is (almost) back together and ready to be started again. Things that I fixed or changed: Full turbo removal, fitting back the OEM turbo oil hardlines. Had to do quite a bit of research and parts shopping to get every last piece that I need and make it work with the GT2860 turbos, but it does work and is not hard to do. Proves that the previous owner(s) just did not want to. While I was there I set the preload for the wastegates to 0,9bar to hopefully make it easier for the tuner to hit the 370hp I need for the legal inspections that will follow later on. Boost can always go up if necessary. Fitted a AN10 line from the catch can to the intake hose to make the catchcan and hopefully the cam covers a slight vacuum to have less restrictive oil returns from the head and not have mud build up as harshly in the lines and catch can. Removed the entire front interior just shy of the dashboard itself to clean up some of the absolutely horrendous wiring, (hopefully) fix the bumpy tacho and put in LED bulbs while I was there. Also put in bulbs where there was none before, like the airbag one. I also used that chance to remove the LED rpm gauge on the steering column, which was also wired in absolute horror show fashion. Moved the 4in1 Prosport gauge from sitting in front of the OEM oil pressure gauge to the center console vents, I used a 3D printed vent piece to hold that gauge there. The HKB steering wheel boss was likely on incorrectly as I sometimes noticed the indicator reset being uneven for left vs. right. In the meantime also installed an airbag delete resistor, as one should. Installed Cube Speed premium short shifter. Feels pretty nice, hope it'll work great too when I actually get to drive. Also put on a fancy Dragon Ball shift knob, cause why not. My buddy was kind enough to weld the rust hole in the back, it was basically rusted through in the lowermost corner of the passenger side trunk area where the wheel arch, trunk panel and rear quarter all meet. Obviously there is still a lot of crustiness in various areas but as long as it's not rusted out I'll just treat and isolate the corrosion and pretend it's not there. Also had to put down a new ground wire for the rear subframe as the original one was BARELY there. Probably a bit controversial depending on who you ask about this... but I ended up just covering the crack in the side of the engine block, the one above the oil feed, with JB Weld. I used a generous amount and roughed up the whole area with a Dremel before, so I hope this will hold the coolant where it should be for the foreseeable future. Did a cam cover gasket job as the half moons were a bit leaky, and there too one could see the people who worked on this car before me were absolute tools. The same half moons were probably used like 3 times without even cleaning the old RTV off. Dremeled out the inside of the flange where the turbine housing mates onto the exhaust manifolds so the diameter matches, as the OEM exhaust manifolds are even narrower than the turbine housings as we all know. Even if this doesn't do much, I had them out anyways, so can't harm. Ideally one would port-match both the turbo and the manifold to the gasket size but I really didn't feel up to disassembling the turbine housings. Wrapped turbo outlet dumps in heat wrap band. Will do the frontpipe again as well as now the oil leak which promted me to tear apart half the engine in the first place is hopefully fixed. Fitted an ATI super damper to get rid of the worn old harmonic balancer. Surely one of the easiest and most worth to do mods. But torquing that ARP bolt to spec was a bitch without being able to lock the flywheel. Did some minor adjustments in the ECU tables to change some things I didn't like, like the launch control that was ALWAYS active. Treated rusty spots and surface corrosion on places I could get to and on many spots under the car, not pretty or ideal but good enough for now. Removed the N1 rear spats and the carbon surrounding for the tailpipe to put them back on with new adhesive as the old one was lifting in many spots, not pretty. Took out the passenger rear lamp housing... what do you know. Amateur work screwed me again here as they were glued in hard and removing it took a lot of force, so I broke one of the housing bolts off. And when removing the adhesive from the chassis the paint came right off too. Thankfully all the damaged area won't be visible later, but whoever did the very limited bodywork on this car needs to have their limbs chopped off piece by piece.   Quite a list if I do say so myself, but a lot of time was spent just discovering new shit that is wrong with the car and finding a solution or parts to fix it. My last problem that I now have the headache of dealing with is that the exhaust studs on the turbo outlets are M10x1.25 threaded, but the previous owner already put on regular M10 nuts so the threads are... weird. I only found this out the hard way. So now I will just try if I can in any way fit the front pipe regardless, if not I'll have to redo the studs with the turbos installed. Lesson learned for the future: Redo ALL studs you put your hands on, especially if they are old and the previous owners were inept maniacs. Thanks for reading if you did, will update when the engine runs again. Hope nothing breaks or leaks and I can do a test drive.

      No those pads are DBA too  but they have colors too. I look at the and imo the green "street" are the best.

      Yea - I mean I've seen my fuel pump which is decades old and uh, while I'm not saying this with real knowledge... but I sure get the ick at using anything in the fuel system that produced the state of that pump. Many years ago I went through multiple pumps (and strainers) before I dropped the tank to clean it out with extreme violence. I'm talking the car would do maybe 50km before coming to a halt, which resulted in me cleaning out the filter with some brake cleaner and going on my way. None of my stuff ever looked like what came out of your fuel tank. I don't think I'd be happy with it unless every single component was replaced (or at least checked/cleaned/confirmed to be clean here).

      I'm not going to recommend an EBC pad. I don't like them. Just about anything else would suit me better. I've been using Intima pads for a while now.
