what said above is don't under estimate OEM, until you reach the limits.

Don't buy gear that's unnecessary for the power level wanted

Not sure what you ment buy that, the car has had a lot of work even before the upgrade. I had already maxed oem before I spent money on the turbo injectors computer intake and manifold so that makes no sence.

Yes it has an front mount intercooler I just didn't list it. Prob got a few others I haven't said

What manifold is it running? Are you getting adequate flow to the wastegate?

IE its not a china stainless manifold with a meter long WG pipe is it?

What do you mean max it at? We had flat 11.6 afr. 18 psi and it slowly dropped back to nearly 14 psi may that have been my problem?

I can't remember when or how much the microtech was its a plug and play with hand controller.

Not sure if it's a china manifold. It could be. It's got 2 pipes that join the collector and joint to 1 pipe to the gate

You bought crappy parts and thought it would add to your power goals. Many others have done the same thing, don't feel like we are singling you out. All you needed to max out the GT3076 was a 3 inch exhaust, turbo, decent modern injectors and a Walbro 255. A decent ecu (adaptronic etc) wouldn't have cost much more than the Microguess.

you mean micro-iceage/Neanderthal? lol fuark man I road tuned a car with it before, I was so close to just calling it quits.. it's was built by morons.

1x table is just RPM vs. ignition (yes there's no load) and there's another table for load and how much ignition you would like to shave off.. LOL..

you said " I had already maxed oem before I spent money on the turbo injectors computer intake and manifold so that makes no sence."

So I ask again, what did you previous setup max out at? and what did it comprise of?

Guys are making 200kW with stock injectors/manifolds/turbo/coilpacks etc.. with just more boost & ignition/fuel maps optimised (either through a toshi remap/Z32 new ecu, etc.)

My last set up was

Stock turbo

14 psi

Cooler

3" straight exhaust

Coil packs

Blitz boost controller

Bosh 040

Tuned remped computer

Can't think of anything else, made like 186 kW I think

I don't think most of my parts are cheap and crappy.

Garret gt3076r .63

Pro gate

Denso 880 injectors

Greddy copy plenum, been machined flat. So just like a genuine

Unsure of exhaust manifold but my friends vl has the same one making 589hp on 20psi

Blitz duel stage boost controller was told it was great!

Microcrap lt12 well I took some bad advice on that one

Turbosmart fuel reg

Bosh 044 pump off a relay for 13.8v

Can't remember what else.

The suspension and underbody is well ajustable everything. The car had cost a lot.

I think I'm about 70hp shy of what I thought I was building the motor for.

Mark did say the air temp adjustment prob was not in the engine bay and may have robbed me of a few hp?

The stock manifold was cracked and old and not a high mount set up and needed to for external gate.

Boost controller is a blitz duel stage. I can send a pic if u like? I had to change the fuel pump on the dyno because the old 040 let go. It's now a 044.

Maybe I just have a really tied motor. I'll do a compression test soon.

I know the microtechs are not the best but I didn't think it would cost me this much. Mark said he thinks the .63 is to small and that's y it drops boost off back to wast gate spring pressure.

I thought maybe some one might have had this sort of issue in the passed. I pretty much just copied someone's setup n thought it would work so I dunno what about a boost leak some where?

I was going to ask what the condition of the engine is like. Do a compression test and see if you can work anything out.

and you definently need a printout of the dyno graph. That will tell alot more of the story

not all 3076's get 300kw on 98, mine with gtx3076 0.83 external gate was limited to 278kw on 16psi, it just wouldn't take more timing so a 0.63 would of been even worse,

mine would rise 10kw per 1psi, so with 18psi you might get 265kw which maybe quite normal.. mine was running 175psi each cylinder which I thought might of been the reason,

run some E85 and you might find it will smash thru 310kw

You should get more power then that - mine is 284rwkw but with a little bit more timing I have gotten it to 294rwkw however on some loads would ping so safe at this.

This is just on straight 98, my gate is welded on the back of the turbo housing.

Similar support mods, obvisously different ecu and tuner but for your reference:

    • I did a bit of googling, the color MCM used was Galaxy Grey from House of Kolor. This is actually a colour I picked out about ~10+ years ago (or more). This one is a stock BMW colour, I guess over the years I figured it was smart to get an OEM colour that was pretty common for all of those sensible reasons one can think of..
    • I absolutely love having clean wheels and also totally love cleaning them. Its not as important to me to have a clean car exterior as it is to have clean wheels. So I bought a kit. I generally use different products for my wheels than anything else, so I thought I'd buy a proper kit and bucket to keep it all in. I got this one from Waxit. I also got the CQuartz wheel and plastic ceramic along with a bunch more application micro fibre pads as CQuartz never provide enough.  The kit was good, but as usual the big, long spongey thing didn't fit between my spokes, so I needed to use a detailing brush and a larger brush that I already owned (been doing this forever, the spokes on these wheels are frustrating.) I did a full clean with the wheel cleaner, it has an iron killing product in it, so I found that I could just use the cleaner and nothing else on the wheels. The tyre cleaner and handled brush were awesome. Made cleaning the tyres so easy. Once everything was clean, I decontaminated with isopropyl and applied the ceramic. Two coats. I bought 2 bottles as I have a lot of wheels to do, half of one bottle did two coats on these. The X5 has 20's so I reckon probably 3/4 on that. Then, for possibly the best part, the wheel cleaning kit comes with a tyre black applicator. But, this is possibly the greatest sponge of all time - its a great size, quite stiff and HAS A COVER! When you finish applying the black, you just put the cover back on! This is revolutionary, I normally have to try and find safe places to put my tyre black applicators as they are covered in silicone and tyre crap. Or, you use something which just falls apart. This applicator is the bee's knee's. Get one. It's worth it. The tyre black is also like a cream, its very thick but goes on really thin, its very easy to use with the applicator. Ayway, after a big clean, decontam, ceramic coat and tyre black the wheels went back on and they look awesome.   Thought I'd share. 
    • Haha. Good work. I feel some of your pain because I spent a bunch of time under my car over the period too. Probably nowhere near as much as you did. My happiness is similarly improved by obtaining a desired result though. Those side skirts are.....hecking. Very unfriendly for street and hoist. Sounds to me like you've made a cart that needs to be driven up only planks/blocks at a 2 post hoist, rather than trying to get it up onto a 4 poster. It's very pretty, by the way. Somewhat reminiscent of Marty's squid ink on SuperGramps - at least in the photos.
    • Absolute Legend 🍻 After fighting with the scanned ones for the last 10 years this is a God send 
    • ATTAKD 356mm Brake Kit for R34 GTT or R33 GTST. Same brake kit as per here from JJ: https://justjap.com/products/attkd-brake-kit-nissan-skyline-r34-99-02?currency=AUD Can confirm these will bolt directly to a R33 GTST with 12mm bolts OR to a R34 GTT (which is what I had) with the supplied bolts and the collets for the 14mm bolt holes in the R34, which are included. Also included is a set of rotors and hats, as well as 2x brake pad sets. 1) DBA XP (street, hills) 2) Forza FR6 (track) These are radial mounted and bolt directly to R33/R34. You will need extended brake lines to avoid them being full stretch on lock - this is common for all BBK's with the bolt point being in the center. In my case I welded another stud about 25mm lower than the OEM one and retained stock lines and fittings. You'll want a BM57 BMC to get the most out of these. I speak from experience. $1800 (neg for SAU people), located SE Suburbs Melbourne.
