If you read it, It does say that the 3076R is the best turbo for a 2.4 lt engine matey, But I would of thought that it would also work pretty well on a tuned SR20 motor as well, But from reading that info who could possibly need more than the 430 WHP that you can get with a 3071R ? 8) .
And full boost before 3000 RPM :shock: :der: .
My own turbo will only produce a little more top end power but doesn't hit peek power to 5500 RPM, I know what one I'd rather have under the bonnet ;-) .

I could check laptop at home but it was either an evo or other tuning co who were developing kits best suited to 4cyl engines..
The 3071 was for 1.8-2.0 4cyl applications.
They found the 3076 best for 2.4 as stated.
On the power front, as Rob states the 3071 more than covers the majority of our needs, and with significantly better spool time than any other turbo.
The choice of AR and inlet will affect this, but not by a whole lot.
Even the smallest 3071R-WG with .64AR and 2.75" inlet seems to be capable of 450bhp at full boost. This is actually probably my weapon of choice. Especially as it bolts straight on and the inlet clears the gearbox when using standard mani. ....

If you read the write ups on here about the particular spec you'll find that it was the version that gave Stu (Dooie) such bad boost creep, this was sorted by the wastegate valve being enlarged and flowed a little. The .86ar version I got has never suffered from and creep and as mentioned already hit 1.77 bar by 3000 rpm.Fazz said:
The .86 ar version is the one to get :-D

However Jim has no such boost creep issues with same spec as dooie's, which may be down to the fitting of sensor/boost reading from compressor. As clsoe as possible seems to help.
Although I do think Dooie has a 3" downpipe but Jim had standard, so perhaps this is the cause? maybe the extra flow creates backpressure?
Do you have a low boost setting Steve? Do you have a standard downpipe or bigger?
My boost setting is 1.7 - 1.8 bar and I have the same 3" Janspeed Exhaust as Stu. The boost sensor (greddy Profec B) takes it's reading from the plenum at the moment although I have toyed with putting it closer to the comp housing.
The reason I didn't move the boost sensor feed is that I want the boost sensor to read the boost thats available to the engine not the boost being developed at the compressor.

Some really good info and views about the 3071.
I take it, people who are running this turbo are using it on a built engine, ie. forged pistons, head work etc.
How would this turbo fare on a standard engine, with just a few basic mods done to it, ie. air filter, exhaust, boost controller, FMIC and 550 injectors?
All info and replies appreciated.

I have spent a lot of time and money not counting over 20 years of racing experience setting up the Pulsar, I personaly dont mind a car that understeers on SLOW corners, specially if the road is only around 13ft wide, and there is no room for time wasting oversteer..... But the corner the car was pictured on was a 120+Degree hairpin with an incredable steep entry and exit....and to be honest if the car is not on 3 wheels you not Bloody trying.....so dont try and teach me how to suck eggs.. until you know the full story behind the picture.campbellju said:

PS just for your info D2's are crap.....and you cant just alter spring rates if the shocks are not calibrated for the springs.
PPS to corner quick you have to carry speed all through the corner thats quick in and quick out, This slow in fast out is what is says SLOW.. just because there is a wheel in the air does not meen the car is going foward quickly (infact less drag) that picture was taken on the quickest time I ever set on that Hillclimb by over 1.5 seconds... might not look pretty but I it works. (and the spectators like it to)
PPPS Use the handbrake !!!! You Having a Laugh !!!! that meens you have to dip the clutch which meens no drive and thus no going forward = lost time, might be ok in a Tesco car park at night to impress your girlfriend but not on speed event..were hundreds of a second can mean wining or loosing
