Im no fan of Bill.... he has screwed me and coutless mates of mine... i dont know if we are getting him on a bad day or something, i understand errors happen but he doesnt stand by his work at all.

MTQ is the go if you want a truly professional job,they are located in Regency park a few streets over from the inspection station... (irony maybe)

Failing that, for a REAL highflow... GCG in sydney are the pro's! their highlow is tried and tested and makes proven power ( i could be sponsored by them lol )

MTQ - can they help me build a custom garret turbo ?

When I replaced my turbo about 2 years ago I shopped around and also spoke to a lot of workshops with Dynos.

My general findings were that ATS could make a highflow turbo that could handel 14psi without stuffing up, but that they didnt produce any more power that a standard turbo at the same boost (and in mant cases workshops reported small to medium drops in power)

The only garanteed success story was GCG whost turbos made more power than standard at any given boost, were reliable at over 14psi, and came on early (nearly the same as a standard turbo, which was another problem with other highflows which were laggy)

I went for GCG and am happy with the results, my only other option was to look at an aftermarket turbu HKS2530 etc.

i havnt had mine hi flowed but did have ATS rebuild it when it went bang, that was about a year and a half ago and mine is still kicking on strong, cops its monthly thrashing and loves it!

Other than that i reckon my mechanics who look after my drifter would be able to do it, try giving fours n more a call, tell them luke with the 31 recomended you.

I had mine built by Madaz... Ironic since I have a huge sticker of theirs on my back window :rofl:

They got ATS to machine it out but assembled it back at the workshop.. Made a 50kw increase (tested on dyno).

Was that at the same boost level, or did they increase the pressure to gain 50kw?

And when did the new turbo come onto boost?

Its the answer to all 3 of these questions (Q4 is reliability) that will make it a good turbo or a crap one.

Yeah 14psi before and after.. However, same time I changed turbos I got a bigger exhaust too, which would have helped in power too.

I've only got a highflowed VL Turbo (r31 rb30), not anything major, but that was the difference the highflow made.

Couldn't really tell you the difference in spool time.. Only about 750rpm difference I think, couldnt really notice. But I've kept a small rear housing to keep lag down.

after countless times of discussion with my mechanics i have come to the conclusion of instead of highflowing your stock turbo...why not get something aftermarket that is reliable like a HKS or something....its going to almost cost the same and would be better as you can also run high boost levels....

I called MTQ today and they quited $2850 for a pair or N1 equivalent turbos for the R32 gtr. he said theyre bolt on but may need some machining to get the oil mounts/holes to line up. dunno specifically what he meant as I dont really know about this stuff, but if people have had problems with any rebuilder, i certainly wouldnt risk my money... on the same token, i dont think im hardcore enough to get my parts made/reconned interstate.... there has to be someone decent locally imho...

ATS! Got mine done there, now is in Steve's car, he can vouch for it too!!!

sure can bloody good turbo

I had mine built by Madaz... Ironic since I have a huge sticker of theirs on my back window :P

?:P i do turbos now :D :D

mine makes more power @ less boost a ATS special cant wait till the dyno day and wind some more boost in

for example @ the PGA dyno day i was running 13.7psi and made 172awkw on the same setup on the Aussie Dyno, dyno made 185awkw same psi 13odd then with the ATS highflow and fouled plugs made 187awkw @ 9psi but couldnt boost any higer due to bad plugs

after countless times of discussion with my mechanics i have come to the conclusion of instead of highflowing your stock turbo...why not get something aftermarket that is reliable like a HKS or something....its going to almost cost the same and would be better as you can also run high boost levels....

its not allways about boosting to a gajilion psi since ive found our standard engine is only good for 17-18psi so thats all the turbo needs to make reliably, its also about ease of fitment highflow will bolt up using oem manifolds and dumps

      Welp, good to know. Will have to wait awhile until steady hands with drills and taps are available. In other news, these just arrived! I will weigh them for posterity.

      100% the factory sender is tapered, that is how it seals (well, that and teflon paste or tape)

      Thanks folks - I've saved a few links and I'll have to think of potential cable/adapters/buying fittings. First step will be seeing if I can turn the curren abortion of a port into something usable, then get all BSPT'y on it. I did attempt to look at the OEM sender male end to see if it IS tapered because as mentioned you should be able to tell by looking at it... well, I don't know if I can. If I had to guess it looks like *maybe* 0.25 of a mm skinnier at the bottom of the thread compared to where the thread starts. So if it is tapered it's pretty slight - Or all the examples of BSPT vs BSPP are exaggerated for effect in their taper size.

      Have a look at that (shitty) pic I posted. You can see AN -4 braided line coming to a -4 to 1/8 BSPT adapter, into a 1/8 BSPT T piece. The Haltech pressure sender is screwed into the long arm of the sender and factory sender (pre your pic) into the T side. You can also see the cable tie holding the whole contraption in place. Is it better than mounting the sender direct to your engine fitting......yes because it removes that vibration as the engine revs out 50 times every lap and that factory sender is pretty big. Is it necessary for you......well I've got no idea, I just don't like something important failing twice so over-engineer it to the moon!

      Yup. You can get creative and make a sort of "bracket" with cable ties. Put 2 around the sender with a third passing underneath them strapped down against the sender. Then that third one is able to be passed through some hole at right angles to the orientation of the sender. Or some variation on the theme. Yes.... ummm, with caveats? I mean, the sender is BSP and you would likely have AN stuff on the hose, so yes, there would be the adapter you mention. But the block end will either be 1/8 NPT if that thread is still OK in there, or you can drill and tap it out to 1/4 BSP or NPT and use appropriate adapter there. As it stands, your mention of 1/8 BSPT male seems... wrong for the 1/8 NPT female it has to go into. The hose will be better, because even with the bush, the mass of the sender will be "hanging" off a hard threaded connection and will add some stress/strain to that. It might fail in the future. The hose eliminates almost all such risk - but adds in several more threaded connections to leak from! It really should be tapered, but it looks very long in that photo with no taper visible. If you have it in hand you should be able to see if it tapered or not. There technically is no possibility of a mechanical seal with a parallel male in a parallel female, so it is hard to believe that it is parallel male, but weirder things have happened. Maybe it's meant to seat on some surface when screwed in on the original installation? Anyway, at that thread size, parallel in parallel, with tape and goop, will seal just fine.
