Its a #OOPS# game
I'm pricing it up now, its around $1000 for all panels

And I just got quoted 6-7k to have them all fitted, paneled and paint
That was cash

Yea im NOR happy to cruise up with a couple of people

Can vouch for Chris (clyons8) we have been chatting while he has been developing this. Great guy to deal with...

I will post pics when I receive my set in a detailed build/development thread

DOnt sedans have H145 diffs and the Ute is H165?

Anyone know if that TD04 can be rebuild with a carbon seal for a draw through setup?

Whoa awesome reply thanks John
D - I'm going to investigate water injection once I have it running ok and im in the tweak phase.

John I also agree with your logic with regarding getting spooling happening by 3k and near full boost by 3.5k

So you think the nissan exa or pulsars turbo would achieve that?
And if I wing it with the s13 t25 sounds like that will be more like 4-4.5k?

How hard is it to adjust/change inlet and exhaust manifolds if I get it made for the s13 T25 and wanna swap turbos down the track? Plasma cut & weld new flange?

thanks Guys

I went back to my turbo mate and challenged him with your comments Dave.
His response was pretty good.

He said doesnt matter what people say will work, I was referring to inefficiency. He then said its easy to prove, an engine has a max CFM which you can then plot against a compressor map.

We calc'd it using something along the lines of
CFM = RPM x CID/3456 divided by VE

(was last night over the phone so cant remember the exact numbers)
I do remember we used 1.4 liter engine @ 7000rpm and around 80% effiency

That resulted in around 250 CFM

he then plotted on a GT2560R, 60 comp ar and .6 rear

looked like this




I then sent through some of the dyno pics from other turbo A series off the site.

What do you know, if you look at them for about the first 4000 RPM there graphs are almost like a non turbo, then BAM

superfatto what was your T25 front AR

your talk about the H75 head made me wonder what is on my A14.

I just checked, its a H89.

what does this mean? I see in wiki thats most likely a B310 A14?

will this be better for this bigger turbo?

Ok just looked at rear housing it is indeed .64 exhaust

also took a photo of the id plate:




A friend of mine is pretty turbo savvy. He has played around with a lot of them on 4wds.
He is convinced that this turbo is too way too big and a waste of time. He thinks I'd be better off using something off say a Charade turbo or TX3 laser. He simply said a old 1.4 wont have enough exhaust gas to drive a turbo off a modern 2L. Logical argument...

D your comment re "tad big but good with low boost and higher comp"

can you please elaborate?

basically I'm going to run a standard motor. Which from what I have read means I want to run no more than 10psi Max and hope to get the turbo to start producing decent boost at 2000-2500 RPM and maxing out at standard A14 redline of around 6000RPM (that is standard redline yea?)

I just want to know should I abandon this turbo completely as it will simply never do this? The whole just use it and see how it goes doesnt really work when you have to pay someone to make fully custom exhaust and inlet manifold. I dont wanna spend over 1000 dollars on T25 manifolds just to find out its only producing boost at 4k and above.

Thanks in advance guys...

great info thanks guys.
I'll take some pics and look for numbers on the turbo tonight.

From just googling S13 T25 turbo I think mine is .8AR front and .64 rear

I wanna build the ute to run on 98, E85 isnt really an option for me :(
