has anyone evr had a T04Z on a CA18?????

[LEE_08]

Just wanting to know has anyone had a T04Z or larger on a CA if so what were the turbo specs & how did it react with with the CA???what RPM was it on boost & how hard did it come on , what sort of power?

any info will be appreciated

I looked at putting that big thing on mine just to say I had it. looking the map though that thing would be a pig and probably over the surge line from idle to WOT.

That thing is enormous.

That thing is enormous.

I get that a lot, just relax and let it happen.

lmfao..you always know how to liven up threads dont you

[r34 gtr]

Damnit, I walked right into that one.

[themadscientist]

your money's on the nightstand

[r34 gtr]

One year closer to me having you purchase an R32 GTR on my behalf. I want you to know, the second that it is 25 years old, You will be car shopping.

I resort to this because you suck too much to send me a DR30.

[themadscientist]

Earliest one would be an 89, we are at 20 years. You suck at the math man.

You would never fully spool it up. Even on a top speed run from a rolling third gear drop it would struggle. I bet you would get smoked by a car with an S14 turbo as a result. The displacement is so small you would not move enough exhaust to spin it up and you would have to crank the boost up to get the power numbers and that turbo is falling remarkably to the left of the efficiency island at those pressures. I know it looks awesome, I was on the ATP site and had that big screw actually in my cart and had to delete it. It's just too big.

If you must have 700hp you would need to wind that lil guy up to some rediculous RPMs and crank the boost real high. If you are looking for something that will actually rotate bolted to a CA I suggest these.

GT3076R 500hphttp://www.atpturbo.com/Mercha...e=GRT



GT3582R 600hphttp://www.atpturbo.com/Mercha...e=GRT



If you simply must have the Z then just get it. Expect it to do this though. http://jp.youtube.com/watch?v=GHtgC2EsjVg

Now by my calculations which are admittedly amateur at about 2.2 and 30lb/min is a good point, working up from that those three turbos are great street turbo, more potential but less flexible, and maybe a bit too peaky for anything but a race car. Now superimpose that on the Z map and you see just how wrong that compressor would be on a small high-revver like the CA.



I could see an RB26 or RB25 making good use of that, potentially a KA24 or a 2.2 stroker SR20, but the CA is just too small to use that turbo effectively. Somebody chime in if they thing I am wrong but I don't believe I am.

[LEE_08]

I forgot to mention that there will be a 100+ shot of nitrous, running on methanol, 40psi boost and spending most of it's life in the 9,000rpm range.

do you think that will affect how it would react????

I'm really not that good at reading compressor charts,

The guy who does my tunning has to4z on many FJ20's and they spool up quite nice at around 4500rpm

[themadscientist]

Bigger motor and have you seen an FJ20's ports, they look like sewer pipes! I have seen those motors spin up TO4Rs, K27s and T88s

Is he running that high on his? it's clean off the top of the compressor map.

If you trust him and he has actually messed with or at least looked at the CA18 and is still willing to try it, plus the 100 shot of N2O, it's possible.

[NUT-CSE]

How similar are the TO4R and TO4Z?

I remember Rhombus/Yellow Munson's CA18 running a T04R and making 489whp 341ft-lb @ 1.3bar.

Wonder why they never ran more boost??

[themadscientist]

That was a nice build.It is hard to find a compressor map for the old warhorse. I do know HKS replaced the TO4R with the TO4Z in their lineup so I would expect it produces the same numbers with better efficiency. With the ball bearing cartridge and the anti surge porting, on the HKS one at least, it should be that much better.

[float_6969]

I was just going to say that if you could get the T04Z with a ported housing, it might gain you enough on the left side of the map to eliminate the surge.

[dash]

solid one here, should be crazy @2barhttp://www.rhombus-tuning.com/...t=346

look up Tones' build on sxoc project page

is this for your CA18 oz/nz drag record attempt ?any details of your setup/plans ?what is in the 8.85sec ute you posted ?

[themadscientist]

Now let's look at that car. He has a turbo capable of 700+ hp and he didn't crack 500, why?

The T04R shines on RB26s and 2JZs They don't need the ridiculous boost pressures a CA18 needs to make the same power because they displace more air. The R, to a lesser extent the S, and certainly for the Z, they want to move a lot of air at a low boost pressure. The tiny engine can't make the numbers at those pressure, it needs much more pressure.

I would be willing to say that they would make comparable, perhaps more peak power, and definitely a smoother power curve with a 3582R.

[boost_boy]

Well, I do own one and it's been massaged to help my poor little drag CA18get the most out of it. With the right manifold and the type of boost pressures I plan on running, it's going to wake-up or make the engine it's going in puke-up it's very expensive internals during the process.

BTW mine is the ball bearing variant

that's 700 flywheel ? a "700hp" turbo is gonna take a lot of boost to hit the mark regardless of motor its bolted too489 wheel at 1.4? bar don't seem too far off target, eh.3582 sound like what mobne uses. Had surge problems ~2bar. Dunno if he ever got the surge ported compressor housing and if it solved the problem.Does 497hp atw seem down for that (what? 650hp) turbo ?Conincidentally, both of those street S13s ran 11.2sec at the stripFor a drag CA18, I'd start by analysing the 8.8sec ute he posted.Figure out what weight and hp you need, then choose a hull, chasis and transmission
