looking good mate. the HKS manifolds are good. there is definitely some merit in bridging the mani's (at least on paper). and the apexi turbos are great too. I have only been in 1 GTR with them and not driven it, but have tried them on a few other cars SR20s etc. and they are definitely good. :P

I had an Apexi turbo (AX53B70 P25) on my RB25, it was great made good power (250rwkw at 18psi) and my tuner remarked that it was one of the most responsive turbos he had tuned. However as i found out to my detriment they do not like to be oversped being ceramic turbines they will crack, get unbalanced ang break the shaft, they are no where as bad as stock turbos and if you keep the boost under 20psi you will be laughing!

are they ceramic turbo's? that cant be a good thing :P

no, definitely not ceramic. i have seen configurations which include these turbos running fairly high boost. ie 1.8bar plus. if they were ceramic, i doubt they would hold together under that sort of pressure.

wow, epic mate!! going for a very similar build myself except using the t517z option. ran them for 5000 km on factory motor.. engine went up to builders yesterday arvo. some of my internals arent as flash but your detailed build thread will certainly help when the time comes to put mine back together. ill be following this thread for sure. its inspirational!!

thanks!

The turbos are definatley not ceramic wheeled. The Apexi range of turbos are a very good turbo and I am confident that they will make good power. These turbos will have slightly more lag on a 2.6lt than a pair of 25/30's or -5 garrets due to their slightly larger size but will make really good top end with good mid range response.

Atomicbomberman and myself have both been extremely busy with work and some other commitments so there has not been a great deal of progress but there should be some updates on the build coming soon.

updates updates updates.... damn it!

Ok, sorry ive been a bit quiet. Photos are all over the place, and i need to get them into some sort of order. I've got so many photos. sorry if the picture sequences get a little long winded. I'll try to pick up where i left off.

Here is a front view of the turbos mounted on the manifolds. For those with a keen eye, you will notice that there is a 5mm stainless spacer between the manifolds and the turbo exhaust housings. This was because there was a clearance issue where the turbo housing slightly interfering with the manifold. I think this was due to a mixture of brands, HKS manifolds, Apexi Turbos and Tomei dump pipes. This is another example of where Daz doesnt cut any corners. Any other builder would have probably jammed in a few more gaskets to get the clearance and be done with it. Instead he had the spacers custom made using a laser cutter for a neat and professional finish.

Water and oil lines were fairly tight together

All hooked up.........

BUT.................................THE LINES LOOKED SO MESSY! The lines in the Apexi kit were way too long.

Daz disconnected the lines and resized them all. Mr RUZIC (Ruzic Engineering) and Dr Tran (9krpm) were both there for Quality Control.

Daz seems to have a tool for EVERYTHING!

MUCH MUCH BETTER!

Disconnected once again to put the heat sleeves on.

Getting closer to the DESIRED look! :) I really hope the Apexi's give the response i'm looking for.

Good to know the Z-TUNE uses IHI based turbines too! If my car runs half as good as the M-speed or Z-Tune i think i'll be a happy man!

Looks good bomberman.. are they Tomei dumps? It is probably in the thread somewhere but c'mon it is Friday!

Thanks bigmikespec, yes theyre tomei dumps with ceramic coating.

those last 2 images are cool - what application did u use? or did hang the engine with fishing line haha

Come on marko! get with it! everyone knows these are all untouched images! The shot was taken with high shutter speed while i was peforming "short bursts" of levitation. :P

Daz used multi layer hi temp silicone hoses for the oil return on the turbos. Bought the right bends and cut them to size. Very neat and tidy. I cant believe how expensive these were!

Rear turbo. The gooey stuff between the the return line and the block is not oil. Its a sealant for the gasket.

    • It is a kunfine Android screen . Does anyone know the wirering diagram of the fuga ??
    • just an update to this, poor man pays twice  Tried sanding down the pulleys but it didnt do the trick. Chucked another second hand alternator in the na car which I got for free off my mate and its fixed the squelling. Must have been unlucky with the bearings.    As for my turbo car, I managed to pick up a cwc rb alternator conversion bracket + LS alternator for 250 off marketplace, looked to be in really good nick. Installed it , started the car and its not charging the battery.... ( Im not good with auto elec stuff so im not sure if this was all I needed to do but I verified such by using a multimeter on the battery when the engine was running and I was only getting 12.2v )   I had to modify the earth strap for the new LS alternator , factory earth strap was a 10mm bolt which did not fit the bolt on the LS alternator which was double the size so I cut it off , went to repco bought some ring terminals that fit, crimped it onto the old earth strap and bolted it up to the alternator , started the car and same issue. Ran like shit and was reading 12.2 at the battery.  For a "plug and play" advertised kit thats not very plug and play but alas.  My question is , am I missing something ? Ive been reading that some people recommend upgrading the stock 80 amp alternator fuse to a 140 amp but I dont see how that would stop the alternator charging especially at idle not under load.  Regardless ive pulled it out and am going to get it bench tested by an auto elec tomorrow but it would be handy to know if ive missed something silly or have done something wrong.   
    • My wild guess is that you have popped off an intake pipe....check all of the hoses between the turbo and the throttle for splits or loose clamps.
    • Awesome, thanks for sharing!
    • To provide more specific help, more information is needed. What Android screen? What is its wiring diagram? Does the car's wiring have power at any required BAT and ACC wires, and is the loom's earth good?
