Angryrb's R33 Street Sweeper

Moving on, i picked up the 6boost low mount off Kyle and began trial fitting it and the turbo which created some issues of its own. The main issue was the wastegate placement, looking at Kyles manifold and reading a few threads i became concerned about the angle of the gate pipe and also the difficulty of actually fitting it in the engine bay and how close it would be to the A/C lines. So i payed a visit to my tuner who advised me that the gate pipe being on a 90degree angle had little chance of working and that it needs modified.

I also pm's some of the experienced guys on here who added some insight, Scotty had suggested a split gate pipe off the housing before and this seemed like the best idea as there was room underneath the housing and as a bonus would make it more stealth. So i had the manifold sealed up and the gate pipe welded onto the housing and then ceramic coated which turned out nice.

The fabricator did a really nice job of this, you can hardly notice there was a gate pipe on it, anyone in Brisbane if your wondering who was doing the fabricating, i used Daniel from Extreme custom engineering at Archerfield. He came highly recommended by MTQ and i was impressed with his welding quality and price. Only thing was some of the aluminium pipes still had some shavings left inside which i cleaned up myself.

This is much better than the last ceramic coating job, the finish looks so good that im half wondering wether it was just painted black and given back to me, but the inside is notably different, im no expert here though.

Apparently there can be issues with the quality of TS ATP housings, the two scrolls do look slightly different but im not sure if that's significant enough to effect anything so hopefully this ATP housing is of a decent quality. It wont be experiencing any extreme prolonged boosting that was mentioned as a cause of some failures during one thread i was reading, so should be fine im thinking.

I think its safe to say that there will be no problem bleeding some boost off , its like an open plug hole . lol

More pics, this shows the compressor cover trial fit before shaving the engine mount

The next thing that need done was some port matching of the turbine housing mouth to the manifold flange, I took a fair bit of material off here with the drill and grinding stone. I used a t3 spacer bolted to the housing to give me a guide and it worked well.

so with the manifold and turbo bolted on, I drove the car to Daniel at Extreme custom engineering, decided to drop it off there at 5am cause I don't like towing trailers in busy traffic. He was starting at 5am so it worked out well, i got the dump pipe modified from the stock position to the low mount position and the intake pipes done.

It was a quick turn around and good quality/value , heres some pics of how it came out.

Nicely tucked away external wastegate, it is a bit of a prick to take on and off unless you own a workshop

I was thinking about shortening the pipe that goes over the rocker covers but ended up with this, i like the blow off valve location but not sure if the pipe is angled that well.. might need to be changed..

i like how its retained the 4inch pipe and the filter is around the corner from the exhaust, its in nice position for a CAI now.

Over the weekend i decided to replace the plenum gasket that has leaked on me twice now, i think the rubber gasket might not be upto the task unless the bolts arnt tightening it up enough. Anyway i replaced it with a cosmetic gasket, and decided that while the car was apart id clean the runners and paint some bits.

this pic shows the top rail with 1000cc Xspurts pretty well

This is the one thing i failed to do when i had it apart! Regretted it ever since

Over the weekend I managed to paint all the intake pipes , rocker covers , top plenum and install the new gasket, took me half the day to get the manifold on because of the fuel rail in the way. I just used some black matt paint in a can, not perfect but I think its looking respectable now.

So with all the pipes back on I primed the engine till I got oil pressure then connected the injectors up and started it, then took it for a drive round the block to test it for leaks. The engine runs very smooth but has a lumpiness about it at idle and wants to stall when at 800rpm and releasing the clutch, it did this before but I thought it was the manifold gasket that was leaking, now im thinking it could be just the cams and tune. First impressions are the noise is very different between this GT and the old GTX, I don't have the boost controller hooked up yet and so I found out I have a 5psi spring in the gate which is suprising. My AVCR must of been working hard to give me 1.4bar on the old setup. I cant compare the two turbo's yet but I must admit I think im missing the GTX's induction noises so far, it used to sound like it was spooling even on the light throttle and the GT is quiet till you step on it... too early to call though really.

With the vacumn line for the BOV not blocked off ( need more hose) I was making some zutututututu noises and Im not one of those guys that like that but just for that drive I embrassed the zutututuututut... and felt like a young tosser that just bought my first skyline, hahahah jokes..

Anyway, need to source a 1bar spring, maybe replace some of the cheap clamps with stronger ones, change oil, do some km's then take it for a dyno run to get result.

Do you notice a difference with the strut brace not on the car?

ive never really given it much thought, so I guess it hasn't made a huge difference

My cars like a go cart, you can take 90degree bends in third gear with no body roll, it just hooks up like its on rails, good fun actually when people are tail gating and you pull off third gear round a corner while there battling the body roll in there falcodore.

I might have a Tial spring here if you need the 1 bar spring. PM me about it.

So is it time for a name change if you don't have GTX goodness anymore?

Yeah I think its time and pm coming bout the spring.

Oh wait, that is worse Maybe to keep it common just drop the X and replace it with 30?

[AngryRB]

lol.. I think its other way round now seeing as I have GT3037 and you have FP, but you got some serious power going on there...

think ill keep it simple and drop the X..

Haha once you hear that turbo you will love it! i do miss it but with the cops the way they are around here i cant afford to be heard

Ahhh, but it is NOT screamer at the moment It can be changed with ease!

Bit of bad luck yesterday, car's been idling bit rough so I blocked off the PCV valve and tightened all the clamps with a rachet instead of screwdriver, started the car and was idling a lot better, but still had roughness to it, bit like WRX or a Rotary.

Anyway decided to drive it round the block, yay!! got boost happening , floored in 4th gear from 2000rpm upto 3000rpm and got 5psi, then it shoots up fast to about 10ish,

was backing off about 3500rpm, then decided to give third a stab , this time it shot upto 16psi and two things happened, the left wheel inside guard plastic came off and at the same time the car seemed to make a backfire thru the exhaust and stalled... Since then it wont start, it cranks but nothing... dam it!!

Im bit puzzled as to what happened, no pipes have been blown off, Im thinking that the CAS has broke or the timing belts jumped a tooth some how, the Knock levels were under control, what else could it be?

Could be time to leave it alone, save some $$$$ and leave it with tuner

Aw dude that sucks. I've had my cooler piping pop off at full noise 20+psi before and the engine instantly stalled and made a big "Booofffffff" noise releasing the pressure, I was sure I'd blown the motor or something, but it was the outlet silicon join from the turbo. Check that first (since yours instantly stalled like mine under load/pressure).

If it isn't that, you can check fuel flow to the rail (can hear itrushing through rail when you prime it) or pull the return hose off and see if it pumps into a jerry can. If you have fuel then you can check spark by pulling each coil out and putting a spare plug into the coil while resting it on the rocker cover and see if it arcs when you crank the motor (might need another person for that). If you have fuel and spark then yeah you might need a tuner to diagnose further.

Obviously if you're sus about any other engine noises, tapping/grinding etc don't risk her, just get her to an expert. Hope it's not too serious

[AngryRB]

Thanks nick, ill definitely check all those things out, its always had a rough idle and low rpm jerking since I first put the GTX on and tuner said it was the tomei cams that would be doing that but maybe whatever it is has finally come to a head here, be interesting to find out whats happened.

Think ill just leave it alone for a few days, got the shits with it all now..
