K-less's 1996 R33 Skyline R33 Gts25t Sii

[K-LESS]

Thanks GeorgeLow, am definitely looking forward to the tune part of things and getting to finally drive the car again. Will be posting updates and will post results and dyno graphs once done :-).

[K-LESS]

Haven't updated in a long time but managed to get the exhaust and wastegate pipe all installed in April, Today car was towed to the tuners to have all the fluids and other bits done and to get the tune sorted and car ready for a cert. Will post an update, fingers crossed all goes well.

[Looney_Head]

any updates on how the tuning and cert process got on?

[K-LESS]

Looney_Head, there were some issues which are getting sorted out and should be tuned and ready for cert at the end of the week, have had to drop my old fuel rail in as they fuel rail on it was causing problems with not bolting down / seating properly so there was a air leak. There were also some minor leaks which were fixed. WIll keep you updated,

[K-LESS]

Its been a while since ive lasted updated. Long story short now is that the car suffered some issues on the dyno and the engine was fully rebuilt with forged pistons and some other new bits and pieces. Will post up the specs and dyno results soon. Car has been fully tuned.

[K-LESS]

Dyno Sheets and Boost Plot below. Car now has forged pistons and the cams are also slightly different along with some other minor changes. Will post up specs soon.

[K-LESS]

Been a while since I posted, but car is currently getting a Turbo Upgrade and retune as the current turbo was on its last legs. Will post results soon but Turbo has been upgraded to a BorgWarner EFR 7670.

[K-LESS]

So Big Update now. After getting the BorgWarner EFR 7670 put on there, it turns out the CAS was also playing up. So the Power FC has now also come out and so has the Airflow Meter and CAS. Am now running a MaxxECU with Temp Sensor and Map Sensor ETC. Also had Oil Pressure and Fuel Pressure Sensors put in. Final Results are below. Red Line is the low boost every day setting. 15 psi. The Blue Line is the High Boost Setting which I havent dared touch yet lol! 20 Psi.

 

 

[K-LESS]

So I have 287Kw at the rear hubs and 324Kw at the rears on high boost. Feels very violent from 4000 rpm. Am still getting use to it. But am currently loving it ?

Some more pictures. Needs a clean though. Will probably try clean it this weekend on my time off lol.

 

[blah_blah]

Nice!

Can we some some more details?

Stock manifold? Internal gate? If so any issues with Install?

Could the car take any more boost?

 

Also how does the EFR feel like to drive compared to the previous turbo?

 

keep it up!

[Looney_Head]

nice work getting it sorted. do you know what cams are in it now? i bet its a hoot on the road with the 7670.

Hey Looney_Head. It definetly feels great to drive on the road! The Cams in it are Kelford Cams. Specs are:

Intake: 262 And 262 Exhaust 9.30 mm Lift

Hey blah_blah

Yup I used the stock Manifold along with a spacer plate like a lot of people have done for the GT3076 on a stock manifold. The turbo is using an Internal Gate however am running a Upgraded Turbosmart Actuator as per reccomendations. I would say the car could probably take more boost, however I am currently more than happy with the power levels and how it drives. So will just keep it on that for the moment. Car definitely feels a lot better than the old turbo. The old turbo was using a .63 ar housing and was very similar to a gt35. I need some better rubber as it currently feels like it will light up 3rd with ease.

[blah_blah]

Nice, 

 

hows the lag and transient response feel with the new EFR turbo?

 

Any plans for E85?

hows the idle on the 262's? my Tomei 254's don't have much of a lope at idle, are you still running VCT with those cams?

[Lithium]

Nice work, again - must be quite fun

Interestingly enough one of the cars I've been involved with a bit has it's tune all dialled in, VERY similar concept to yours but running stock cams and has an internal gate EFR7064 on the stock manifold.  That hit 300wkw on 20psi on a local rolling road dyno, and feels barely laggier than stock - we'll have to try and give it a run on Prestige's dyno to see what the power equates to on the hubber.

Hey Looney_Head. Still definetly running VCT with these CAMS. Car sounds nice. When you mean lope are you talking about that lumpy cam idle?

Is definetly a lot of fun thanks man ?

The car you mentioned sounds awsome. Ive had a lot of people ask why I kept the stock manifold. I guess I just couldn't justify spending that kind of cash on something that wasn't required. Mind you I ended up doing a lot of things that most probably wouldn't do. I.E front facing plenum, but I just completely dislike the stock setup from a aesthetics point of view lol.

Funny thing about the FFPs, there seems to be a lot of knocking them on SAU but I personally am a pretty big fan. 

10 years ago the HKS GT2535 was deemed one of the perfect bolt on turbos for mild RB25s, and Prestige's dyno happens to have a mates old stock plenum RB25/98 dyno plot from when he had a GT2535 on his back at that time... so we decided to overlay the plot from an early attempt with the EFR7064 (we ran into boost control issues first time out) setup which runs a FReddy plenum, and the EFR7064 setup made more EVERYWHERE than the GT2535... from 2000rpm to 7500rpm, with the gap only getting bigger as the rpm increased.

The GReddy style plenums in my experience offer a nicer wider spread of torque and as you say, are nicer aesthetically and give a bit more room for activities if you go high mount as well

yeah the lumpy cam idle. my 254's don't have any lumpy idle.
