It looks either wastegate is unsealed or VCT is not activated.

Ask Sean to change the VCT settings through the ECU and see it response to power curve. 2ndly the actuator has to be removed for turbo installation and in many cases the pre-load was let by the operating mechanic (many believed they shouldn't be tensioned) or not been corrected adjusted after installation.

Drop the cat, have a play with the EBC, that dip and claiming back up shape looks strange. To get around the 280rwkws mark it needs to hold around 20psi up top.

Further more, pretty much all results came out of the test car are on aftermarket manifolds. I will see Trent next week to trail a larger turbine housing for the SS2, which should compensate a little working with stock exhaust manifold.

I installed turbo to engine, then engine into car. Actuator hasn't been adjusted. But i will check it Saturday morning And test Vct just to be sure.

Might be able to log boost against Rpm then drop Cat and compare and see if it gains much response

Thats honestly a pretty good graph man.. I can imagine you would want boost in as early as possible, and to hit the mark for power, but that is all in by 4k already.

It definitely has the marks of a fast car, and I do believe the turbo is performing based on the shape of the curve. For a turbo thats capable of more power, to me it looks like its not running enough boost, or theres a flow restriction of some sort (other than the turbo). As its only a minor hold back on boost and your missing 10-20% power.

Theres definitely more in it once you work out whats holding it back.

Hi all

I bought on of hypergears highflows around 6 months ago with the intention to put it on my track car, but as life likes to play its little games, the track car was stripped and sold.

But I kept a few select bits to make myself a budget, reliable and responsive daily driven drifter

A r33 4 door, so sticking to the budget I fitted a front mount cooler, a intank fuel pump, the highflow I had (r33 21U rear, 14psi actuator) and a microtech lt16 I had.

Then took it in for a tune, stock injectors(remember budget build) and all

P9200055_zps10e337e0.jpg

So on a safe tune, to handle me thrashing it at the track :P

The injectors had a little left in them at 300hp but 282rwhp (208kw) was the final tune

For the very minimal cash outlay, I'm very very happy with the result

Interesting that they didn't use any correction method, I've never had a run on Allstar's dyno without SAE being used.

Make much difference?

I see mine says 2000+4000 while simonr32's says 2000+3000. Googled last night but didn't find an answer. I know nothing about correction methods so have some studying to do

Yeah I'm not too concerned. But would like to get the most out of it after spendibg so much time and money on it. Regardless I want to change exhaust from behind the dump, check all obvious things then wind more into it. I'm confident with more boost the power curve should be close to everyone else.

But yeah it feels fast as for me after only driving a ford ranger and grand vitara for the last 3 yrs ;)

Great result for a very budget build! That turbo would be good for 18psi at least, so I can see it would really come alive with some injectors and more boost.

Good work, I would be happy with the result of a nice reliable ultimately budget build like that.

Thanks mate, I did consider going the injector path but for the extra outlay I might just stick with this setup, it seems to drive so well and still has the balls to fry tyres rolling onto boost in lower gears.

Either way I am in QR matsuri in 2 weeks so will see how good it goes :)

a cheap option for injectors are S15 450cc injectors, they flow decent amount and can be had for next to nothing on silvia forums :woot:

just read you have a GT-t, fail on my side lol

Not a fail on your side, fail by me, I should update that, I've had 4 different cars since the r34 4 door

This is a series 1 r33 4 door :D

haha well there you go!

S15 450s will get you up to 230kw man, easily.

even more, I was making 246 kW on my old shitbox with the duty cycle at around 70ish %

I dont want to set the bar too high, it is a HF and is running a microguess. The microguess is the biggest holdup, to keep the tune safe I say discount about 20 from what it can do as a maximum.

Make much difference?

I wouldn't have a clue myself, but from memory Simon said it adds 7% to the total power. As does their dyno apparently. So together my power figure is apparently 14% out. I think that's what it worked out to, the question was whether my 393rwhp figure on Allstar's dyno was accurate compared to my 318rwhp on Autoworx Dyno Dynamics a day later.

haha well there you go!

Still a lot of effort for and extra 20 odd kw lol, but I will keep my eye out for some cheapies as I'm always on nissansilvia.com

But I have my basic engine setup I wanted :)

    • Place the new daughterboard in the case and mount it using the 3 small black rivets provided, and reconnect the 3 factory ribbon cables to the new board Then, use the 3 piggyback cables from the daughterboard into the factory board on top (there are stand offs in the case to keep them apart. and remember to reconnect the antenna and rear cover fan wires. 1 screw to hold the motherboard in place. Before closing the case, make a hole in the sticker covering a hole in the case and run the cable for the android unit into the plug there. The video forgot this step, so did I, so will you probably. Then redo the 4 screws on back, 2 each top and bottom, 3 each side and put the 2 brackets back on.....all ready to go and not that tricky really.      
    • Onto the android unit. You need to remove the top screen because there is a daughterboard to put inside the case. Each side vent pops out from clips; start at the bottom and carefully remove upwards (use a trim remover tool to avoid breaking anything). Then the lower screen and controls come out, 4 screws, a couple of clips (including 3 flimsy ones at the top) and 3 plugs on the rear. Then the upper screen, 4 screws and a bunch of plugs and she is out. From there, remove the mounting brackets (2 screws each), 4 screws on the rear, 2 screws top and bottom and 3 screws holding in the small plates on each side. When you remove the back cover (tight fit), watch out for the power cable for the fan, I removed it so I could put the back aside. The mainboard is held in by 1 screw in the middle, 1 aerial at the top and 3 ribbon cables. If you've ever done any laptop stuff the ribbon cables are OK to work with, just pop up the retainer and they slide out. If you are not familiar just grab a 12 year old from an iphone factory, they will know how it works The case should now look like this:
    • Switching the console was tricky. First there were 6 screws to remove, and also the little adapter loom and its screws had to come out. Also don't forget to remove the 2 screws holding the central locking receiver. Then there are 4 clips on either side....these were very tight in this case and needed careful persuading with a long flat screw driver....some force required but not enough to break them...this was probably the fiddliest part of the whole job. In my case I needed both the wiring loom and the central locking receiver module to swap across to the new one. That was it for the console, so "assembly is the reverse of disassembly"
    • But first....while I was there, I also swapped across the centre console box for the other style where the AV inputs don't intrude into the (very limited !) space.  Part# was 96926-4GA0A, 284H3-4GA0B, 284H3-4GA0A. (I've already swapped the top 12v socket for a USB bulkhead in this pic, it fit the hole without modification:) Comparison of the 2: Basically to do the console you need to remove the DS and PS side console trim (they slide up and back, held in by clips only) Then remove the back half of the console top trim with the cupholders, pops up, all clips again but be careful at the front as it is pretty flimsy. Then slide the shifter boot down, remove the spring clip, loose it forever somewhere in the car the pull the shift knob off. Remove the tiny plastic piece on DS near "P" and use something thin and long (most screwdrivers won't fit) to push down the interlock and put the shifter down in D for space. There is one screw at the front, then the shifter surround and ashtray lift up. There are 3 or 4 plugs underneath and it is off. Next is the rear cover of the centre console; you need to open the console lid, pop off the trim covering the lid hinge and undo the 2rd screw from the driver's side (the rest all need to come out later so you can do them all now and remove the lid) Then the rear cover unclips (6 clips), start at the top with a trim tool pulling backwards. Once it is off there are 2 screws facing rearwards to remove (need a short phillips for these) and you are done with the rear of the console. There are 4 plugs at the A/V box to unclip Then there are 2 screws at the front of the console, and 2 clips (pull up and back) and the console will come out.
    • So, a bit of a side trip, but one that might be interesting for people with JDM cars and japanese head units. I know @Pac previously posted about a carplay/android auto adapter he installed which used the AUX input, and @V35_Paul put in one of the Tesla style units that replace both screens. The option I went with was a Lsait LLT-YF-VER5.87_2 (https://www.alibaba.com/product-detail/Lsailt-8GB-Android-Multimedia-Interface-for_1601187633672.html). Price was $1,150 for a single unit although they are much cheaper if you are willing to buy 2....$857ea. Make you you get the version 2 not version 1, it is faster and has a better UI - this is the manufacturer listing: http://www.lsailt.com/product/348.html. BTW if you've never bought from Alibaba before, don't be concerned....these guys can't stay in business unless they are responsive, ship fast etc, they were excellent (probably faster shipping than most local places) So, this was my task for a lazy Sat afternoon....looks complex but was all done in a few hours (it probably helps that I had some of it apart before so it was a bit familiar). I also decided to add a HD USB drive recorded at the same time and the unit also supports an aftermarket reverse cam (if you don't want to retain factory) and also AV in and HDMI out It looks much worse than it is, in fact in was genuinely all plug and play (no custom wiring at all). This video was pretty good (skipped a few steps), unfortunately they are an Aussie seller but no longer sell this unit (I guess Carplay/AA adapters are easier to install and much cheaper) https://www.youtube.com/watch?v=T5hJfYOB8Dg
