Hey Everyone,

Ive pretty much finished my R33 Build today with the completion of a tune on a DynaPack Hub Dyno, it didnt make as much power as I hoped (was wanting 300RWKW) but the results were 353.08RWHP/263.29RWKW on 19.7PSI with 450NM Torque by 5100RPM tuned on BP Ultimate.

The set up is as follows:

HKS 3037 Pro S with a 0.68 Rear (full bolt on kit)

HKS Induction Piping

HKS Split Dump

Blitz 3" Front Pipe

X-Force 560CFM Highflow Cat

3" Straight Through Exhaust

Low Mount Stainless Manifold

Hybrid Front Mount Intercooler

Turbosmart Stage 3 Plumb Back BOV

Apexi Power FC

Apexi Power FC Boost Control Kit

740cc Nismo Injectors

Z32 Air Flow Meter

Exedy Cushioned Brass Button Clutch

Walbro 255L/h Fuel Pump with 14.4V Relay Feed

Aus Spec Tein Super Street Coilovers

Tein EDFC (Electronic Dampening Controller)

I've included some pics of the car under the bonnet and inside the cabin, the cars still at the mechanic/tuner as one of the rims got bucked and has been sent off for repair but ill post dyno sheets once I have got them (should be Friday) and the pic of under the engine bay was before the Suspension Install ill take another one once the strut brace has been fitted once it arrives.

chuck up the graph, and i will have a look for you (i have a new dynapack) torque is good but yeah power is a bit low for the boost, a .61 3037s made 289rwkw on my sr @ similar boost.

when is full boost reached?

from what i believe 4500RPM Nizmo_freeks makes full power by 3750RPM however that was at 17PSI. one of the cooler pipes has been reduced in diamater by having a fan blade smashing into it by approx 1/3 (top pipe going across the fan). Would this constitute a significant restriction of flow? I was actually planning on replacing them with a stanless set as they where chrome plated and its starting to peel off anyway.

After replacing the pipe would I need to retune the car? Thats the only thing i could see being a problem as everything else is brand new.

As for unbolting the exhaust, it has a brand new Blitz 3" Front Pipe, Brand new High Flow Cat, a 3.5" exhaust with no mid muffler and only the Canon on the rear so i dont think that would be the problem but an idea ill mention tommorow. Im hoping its still on the dyno as they were meant to be checking the cold start tommorow and it was tuned this afternoon.

Hmm... Money... haha im so broke right now, theres $14-15K just in parts in that list including the tune and a few other supporting mods, its all pretty much been done in the last 6 - 8 months whilst its been off the road and thats not including installation as ive done everything but the clutch myself. I get my license back in 3 weeks! so looking foward to taking it for a drive.

Jury out but I'm highly suspicious of stainless direct replacement exhaust manifolds for RB20/25 , I think the factory did a good job on the std iron lump and it's not nearly as bad as many would like to think . It's not a competition std manifold but is was designed by people who have the smarts .

I reckon I'd smooth up the std one and refit it for trial purposes .

Again (IMO only) I think I would have opted for the 0.87 A/R ProS turbine housing mainly because HKS go to the trouble of trying to make their spec turbos responsive , things like the nicely designed turbine housing and the port shrouded comp cover .

The .82a/r Garrett ones are perfectly nice to use, and I run a stainless direct replacement and it is definitely a noticeable improvement over the stock one but having said that, the stock one was definitely not bad. I had a look into cleaning up the stock one and using a dremmel there isn't really much more you can do other than port match, unfortunately in NZ we don't have the option of extrude honing these things.

I run in the 270-280wkw on 1bar of boost on a Dynapack hub dyno with mine, so I definitely feel something is amiss with yours.

your making the power of a 2835 but requiring more boost, but im not sure how much hub figures wary from wheel figures? certainly looks like you have all the right supporting mods to make the power.

Sure you havent gone for a little spin around the block yet? :D I know i would have :(

Actually i think i made a mistake, i think its actually on 18PSI. I will have them in my hand friday, however i have to find a scanner :S.. aparantally i have like 6 pages of data. It also seems that i have quite a major vibration (have always felt it) at higher RPMS which has been deemed to be the diff and the vibration can be seen on the back hubs.. would this be affecting power?

Hmm doubt it but you never know. Most likely the cradel bushes are worn and causing the diff to move slightly. Most skylines have worn cradle bushes after so many years of use. However yeah it could be the diff itself.

it will be rear wheel bearings.

    • Yeah, plenty of air flow, there is a dedicated path that feeds the air in to the OEM intake tube behind the bumper As for a "tangible effect", maybe, but getting the pod/intake air out of the hot engine bay is worth it psychologically to me, even if it gives no performance difference, so the tangible effect in my Lizard brain saysss yessss  In the end, to me a tangible effect isn't always about performance, sometimes it a sound or a look, or even a...... feeling  Ooga-Chaka Ooga-Ooga Ooga-Chaka Ooga-Ooga Ooga-Chaka Ooga-Ooga Ooga-Chaka Ooga-Ooga
    • yeah first and reverse is where you will find clutch release issues (whether hydraulic or mechanical) because the difference in revs required is the highest there; particularly changing down from 2nd to 1st when still moving. To be clearer though, it is possible that the clutch release bearing is the wrong height. This is less likely than a hydraulic issue but it is not unheard of when you are mixing and matching
    • Quite right, if you make it to that pension you deserve every cent
    • Hi all, Restoring r33 series 1 rb25det. All the heater hoses were on their way out, have replaced them and put it all back together. After testing I noticed a small leak from behind the head on the actual metal water line to the turbo when cars warm. I tried running a longer hose over it but it kept leaking...   I am about to take the (stock) manifold off again😔 to change the water line does any one have any lines they recommend? I was looking at Aeroflow Turbo Oil & Water Line Set but not sure what everyone else recommends. Car is completely stock but want to upgrade turbo eventually. it looks like ill have to disconnect a lot just to replace these lines so if there's anything else recommended to do please let me know. Thank you in advance!
    • From memory, on the R33 GTSt at least, while everyone says "It's not adjustable", I found when I changed clutches in mine, it just needed a small adjustment on the rod length. But be very wary here, as you could end up trying to push the pushrod in the master too far, or blowing out the slave.   Most likely though, if the master/slave isn't bypassing internally or leaking out, then the throw out is the wrong height compared to the fingers on the clutch, so when it moves to disengage the clutch, it isn't 100% disengaged. You can check part of this out too by jacking the car up, having the engine running, put your foot on the clutch and try to engage 1st gear. If it goes in pretty easy (Compared to the ground) and/or the wheels start turning a fair bit and it takes a bit too much brake pedal to bring them back to a stop, this is likely the issue.  I'm not sure if you can adjust the height of the forks etc in these though, it's been that long since I've touched any RB gearbox.
