I am looking for some pics of the HKS lowmount cast manifold fitted on an RB20/25 motor. I can't seem to find any. I want to see how tight it fits with a larger T4 turbo. I am mainly looking at the compressor clearance. Google's search came up with nothing and even searching for HKS Manifold gave me 100's of pages with no pictures.

I have a Turbonetics T66 mounted on an RB26 cast manifold and it clears easily. Having compared the RB20/25 manifold with the RB26 manifold the only difference is the bolt pattern to the cylinder head. :rofl:

Well I have a T3/T4 with an E compressor cover. The HKS manifold I have is already studed for a T3 flange. I was hoping to be able to make my own mounting holes so I could angle it a bit if need to clear my steering shaft (Dam LHD cars) From what I have heard from others who are using the manifold in there S13/S14's is that you can't use the larger S compressor housing because it hits the motor mount. Right now I am using an adaptor box with an external wastegate plumed into it.

Sorry, we're right hand drive downunder same as Japan.  My turbo is nowhere near the engine mount though.  We can buy T3 to T4 adaptors off the shelf, no need to make one.:rofl:

This is what I had made to fit the turbo to my stock manifold. I look at it as a poor flow design so that's why I want to go with the HKS manifold setup. It also forces the DP to make a sharp bend to clear the steering shaft.

Hi

I have the hks manifold on my rb20 with a hks to3 on it and a hks 35mm external waste gate and found i had to modify the engine mount heat sheild so the compressor air intake was clear the pic's are to large to upload though so i cant show you

cheers peter

    • What 1.5 way? There's no such thing really as a 1.5 way, just different ways of explaining 2 ways with different ramp rates. HOWEVER. In any driving in a straight line your 1.5 or 2 or 1.7 way should have no clunking at all. With the clutch fully depressed the diff should be silent (unless it's welded but I'm assuming it's not). Something aint right here.
    • Clutch is a spec brand, new clutch system,( PP, flywheel, friction disc, etc. pull type) installed 100 miles ago, with no problems.
    • looking for some help and maybe some insight on others experience with a new LSD. R34 GT ran and drove beautifully, but always alot of grip loss due to the open R200 rear end, so I just installed a new 1.5 LSD way into the stock open R200 for a ER34. Simple. Everything seemed right. I test drove for the first time this weekend. as I started to back out the garage the first time slowly with tires straight it sounded and felt like I had a loose or half disconnected drive shaft...that was clucking around loose and shaking entire vehicle, and making it feel like the trans clutch was spontaneously slipping then grabbing very roughly while just letting out pedal slowly. I backed it out went to pull forward with the same noise, shake and slip grab feeling with hesitation, I turned the tires to back out more and then pulled ahead some same thing but worst because of added wheel resistance (which that I expected) puzzled … pulling it back in checking everything over and finding nothing wrong, I tried it the next day. same thing, couldn’t believe how it shook everything again making a terrible noise and making it feel like the trans clutch was slipping and grabbing, but I got it out of garage into the driveway, got it straight, drove forward and then reveres a few times in a straight line everything shaking , causing what felt like clutch slip and grab every time, sounded like right behind front driver tire and I could feel it in the floor board with my feet,... worst right when beginning to let clutch pedal out to engage slightly, shuttering and sounding terrible along the way…I managed to slowly get down the road, babying it the whole way, once I was rolling (out of 1st) seemed to be better and between shifts, then clutch felt closer to normal…not slip/ grab etc., but back down to any stop, straight road or turning, same thing. Made no difference if all tires were straight or if I was turning. All other gauge read out correct. with in 2 miles as planned I reached the empty parking lot and performed the break in procedure that came with lsd, essentially to drive in a figure 8 a bunch.  Did this, binding chattering, and shaking the car the whole way. I drove it back home seemed somewhat normal once I was in straight line and past 10 mph or so, and I know it will “bind” on corners and cause some tires squeal when turning especially from a stop, but when I begin to move it still causes what feels like the trans clutch to slip and jerk badly as well as shaking the entire car, and sounds terrible, that I didn’t expect. I used the fluid they supplied with LSD kit and did the breaking, planning to change fluid as they suggest after breaking, but wondering will it get smoother or less aggressive with use? maybe a 1.5 is just too aggressive for normal road driving?   I have a LSD that I put in my 71 cuda when I restored it, with amazing smooth , quite yet effective results. Different style LSD but that ones a joy to drive. maybe expecting too much from this R200?
