My Gt3071

[skylinecouple]

Hi Guys,

I'll make a deal with you, someone tell me how to post up photos and I'll show you my 3071 with .82 housing. Yes it is the genuine 5023 cartridge. I bought this one to see if guys like Disco Potato were right about it being the perfect street turbo.

The difference with this one is, it is from ATP with the anti-surge holes in the intake. 60mm turbine wheel, A/R 50 71mm compressor. All work carried out by Luis from Drift Garage. Let me tell you he is a great bloke and I highly recommend him. Will probably need to enlarge the dump pipe to four inches as I don't want to go back to a split dump again. Otherwise all is well and the intake is 4" into 3" to original air box. Managed to use the old oil feed but made up braided lines for water. Cut the old metal blow off valve tube and used rubber hose for last 100mm's.

Anyhow, tell me how to load photos and I'll give you more info. Thanks to Dale, Disco, Mafia and Lithium. Good previous posts from all and helped with decision.

Awesome, congrats on the buy Go to photobucket.com, look for something like "join" and click that, follow the instructions and away you go. Its very easy to join and use and costs nothing.

Ah! Was it your car that was down there last week? My mate was in there and saw the anti surge mod and asked me whether they were available for 3071's as it looked like the same turbo as mine.

So the 6 million dollar question, do you have boost control issues with the .8 IW turbine housing?

I also use photo bucket, upload, click the link IMG text box under the thumbnail and paste it in the reply box.

Thanks for that. Will get to work on it straight away. Had to put Luis to work before final tune. Bear in mind I simply don't have any time so thats why this has been a long time coming. I actually had a 3076 coming from the states but then a friend said he didn't want his 3076 so cancelled the order and now friend wants his turbo to go on. So will stick to the 3071 and make the next tune a big one. The power I have at the moment is very good and will inform all at a later date. DaleFz knows the initial results but thats without a tune. Will give you a hint, no tune and boost comes on hard at 3,500rpm.

Stuff photbucket

Just create your own SAU Gallery (top right), less links = faster forum and thread loading.

I''d like to see Gary and Dave meet up to compare results.

Boost control and general driveability comparisons are the two things I'd like to know about - but I remain satisfied with the 0.87 A/R HKS 3037/3076 That unit just gets stronger as the rpm rises (especically past 3000), but no massive torque surge to create difficult-to-control traction issues. To me that was one of the best aspects of that unit, and I'd think the 0.82 A/R 3071 might be similar in nature.

[BHDave]

shouldn't be too hard, we live within a few km of each other if Gary is in Campbelltown.

Though in all honesty mine is nothing to write home about atm. I'm looking at a ghetto ex gate mod to the factory manifold which should (hopefully) solve all current problems, and probably introduce some new ones....

[-33-]

Will be watching closely. I have the .63 housing with minor boost control problems (creep to ~21 psi). I'd probably seriously consider the 0.82 housing at some stage if it worked well. Although I do love the response of the 0.63....

Post up dyno sheets please =D

Out of curiosity how does the 0.87 3037 Pro go at around town speeds and maybe a slight prod of the right hoof ?

Just as a refresh is this engine std mechanically or cams and head work ?

Cheers and thanks , A .

One of many..... i reckon i get 2 a fortnight coming in complaining of that issue..

Hope this works.

Internals are untouched. Around town speeds it responds progressively, delivering predictably and letting you know it's there with the promise of a lot more to come as revs rise further. It doesn't feel insipid, but between 2000-2500 there is noticeably less grunt than available with a 2871 / GTRS installed.

However, this is about Gary's 3071 so let's hear from him a bit more.

Hope this works.

Yes, all from ATP. The machining wasn't really needed but it looked like a really cool option so I grabbed it. The slots are really for anti-surge but that would only be if one used the .63 housing as they make boost very early and the engine simply can't swollow the air. I must say though that the off boost driving is much improved. Even though nothing extraordinary happens under 3,500rpm the pickup is fantastic over the old GCG hi-flow.

Oh, and on the subject of GCG hi-flows, I will never reccommend those useless bloody things again. I spent a couple of grand on the best tuners in Sydney and bloody thing never made more than 220rwkw. Oh, hang on, one tuner did get 240 but the next tuner couldn't believe how much timing he had put in it. I was lucky I didn't thrash it as it would have done a piston for sure.

[R31Nismoid]

Well people all over the forum have made 250rwkw without much drama, Vic, NSW etc.

Could be anything wrong.

Hey Dale, the response with my .82 is quite good. As I said before the under boost response is a huge leap forward. ATP did say that this would be the case. Seems the .50 A/R comp housing moves a bit of air "under the curve" as ATP would say. Can't believe how the exhaust note has changed as now sounds like a very angry car. The final tune is now monday 14th at Unigroup. Yavus is my favourite tuner these days, as he likes to know what you want out of the tune. But 258kw so far and that is not any where near properly tuned. The standard air box may slow things down somewhat and the dump pipe is only three inches. With a 4" dump things will be better again.

yeah thought it was from ATP

bought the same turbo for a customer awhile back with the same anti surge compressor housing but with the .63 exhaust housing and the anti surge realli does make a difference if ur going to be using the .63 housing

I know, but not this little black duck. I strongly suspect GCG screwed up and put a RB20 housing on it, who knows. It would lose urge very ealy at around 5,500rpm in 4th. I could never really put my foot into it as it would just light up the tyres at 2,700rpm. Then lose the plot at 5,500. I once had an SV5000 that was very much the same.

[skylinecouple]

A few more for you.
