CA18DET Turbonetics T3/T4 Hybrid Turbo Ballbearing (s13)

I'm interested in instaling this turbo right after engine forging (I'm not writing about large intercooler, better fuel pump, bigger injectors etc... because those are just essentials...)

take look at t3/t4 http://vecco.com/turbo.htm

1 - Does someone have similiar setup ?
2 - How does this setup works for drifting/daily use ?
3 - How much HP can I get from CA18DET (forged) with this turbo (approx)?
4 - will it have large lag ?
5 - theoretically, Ballbearing should help with "lag" problem, anyway, will it boost on low revs 2800-3500 ?

no theory please, just pure practice...

[Matthew2]

someone ? :whip:

1 - Does someone have similiar setup ?

I don't have a similar setup, but I've worked with them.

2 - How does this setup works for drifting/daily use ?
It works nice, if you don't mind the lag is a thrill untill red line. I haven't drift with this turbo, but because of the lag won't be a good choise.

3 - How much HP can I get from CA18DET (forged) with this turbo (approx)?
Turbo is rated to flow some 500whp.

4 - will it have large lag ?
Yes, untill +/-4k.

5 - theoretically, Ballbearing should help with "lag" problem, anyway, will it boost on low revs 2800-3500 ?
Remember you have a 1.8cc, lag will be there.

Unless you don't plan to build a 400whp drag racer, stick with a GT28 series turbocharger.

basically, I want strong 1.8 (400HP+) with no much lag...

some friend of mine have t3/t4, and it starts pumping at 1800rpm, and he have full bost at 3900rpm on stock intecooler, with stock chip. So probably after some mods it will give full bost at 3500rpm ? or less ?

so just asking...

How about GT3071R-WG Dual BB, Garrett GT3076R, Garrett GT2876R ?

First, your "friend" running a T3/T4 on a stock SMIC is retarded.

Ok, I assume if you are going for 400+ whp you also have cams and a sheet metal intake manifold? The cams will give you a little more lag but will be almost a necessity for those power levels on this motor.

I know the ball-bearing S15 T28 doesn't make full boost til around 3500 rpms so I imagine at least 4000+ depending on the A/R of the turbine housing for a T3/T4 variant. Also, ball bearing doesn't have nearly as much effect on how quickly the turbo spools compared to the gain you get in transient response. The size of the turbine housing affects spool more than anything.

Also let me get this straight-- you want a 400+ whp 1.8L without much lag? It's a big tradeoff dude. Especially when working with a small displacement motor. If you were in the US, I would tell you to go with a turbo KA24 as that would be your best bet.

EDIT: And to make a note, I wouldn't go with a turbonetics turbo. I would look for one of the new Ball-Bearing Garrett T3/T4 units that are out for sale now. All I've ever heard of are horror stories about Turbonetics' turbos.

What kind of power could he expect if he went with the s15 t28? Hows about that turbo and some Tomei cams.....256's with 8.5 lift??

not to thread jack, I bet he would like to know as well.:wiggle:

how much boost can they flow safely by the way.....s15 t28?

well, right now he have some money probs thats why :D

yup.

which means that, when I want bigger boost on low revs I need smaller turbine housing ? well it should be right, smaller space to fill / air flow should be faster / faster spinning / more boost. But it also means less power. How about turbo with smaller turbine housing, and larger compressor housing + bigger wheel ? should be fine for smaller engines. What I mean - wheel in smaller turbine housing is spinning faster than wheel in bigger turbine housing when using smaller engine. So it should give same spinning power as bigger engine with bigger turbine housing ?
So, in theory (mine ;) ) when using larger compressor housing + bigger wheel and smaller turbine housing i should get quick response and lot of boost ?
that would be niiiiice :D

europe. but we have some 2.4 too. better idea will be sr20det, but it also means at least $3000 of spending :D

got any url ?

using t28BB in ca18det, You will get max approx 300HP on stock engine internals. Of course, with intercooler, fuel pump, modded chip etc. Mine is running approx 270HP with 2,5 exhaust. Can't go for more because of stock injectors :D

here you have ca18det with gt2871r http://animedvd.pl/200sx/wykres.jpg
just remember that's not full boost from this turbo. and he have also stock internals.

Yeah, thats a waste of money. Ball-bearing T3/T04E 50-trim with a .63 A/R is all you need for the power level you want and they are around $900. You COULD go with the .48 A/R turbine side for a little more response, but I think you would be cutting it close on the 400whp mark.

[ryangreg]

Speaking in terms of that t28.....would those camshafts help increase max power, or simply move the powerband higher in the RPM range??

The only cams that are really worth it with the T28 are a set of 256/256 or MAYBE a 256/264 combo. A guy on NICO dyno'd 289whp with the S15 T28. He then put on some HKS 272's and no matter what, he couldn't get any higher than the 250's and his spool was delayed a significant amount.

ok. how about a turbo with...

1 - smaller turbine housing (hot side) fitted exactly to engine size and exhaust flow amount. What I mean - housing + wheel which can take care of engine gases even a bit over rev cut, with no turbo side stall. but not bigger than that.
2 - bigger compressor side + bigger wheel.

turbine wheels are connected, and have same spinning speed right ? so if bigger wheel spinning is the same as smaller, it should pump more air, and pump it faster right ?

some maps also...

Am I right or not ? :D

They all use the same T31 exhaust wheel. Only the housings are different. The smaller A/R will start to choke in the upper RPMs and that's why you won't get as much out of it.

[Matthew2]

thanks for all Your replies :)...

anyway, which turbo (hot side) housing will be the best for going to 500HP ? size... ? if GT2871r turbos are pomping to 400HP and are also very responsive, I suppose I should be looking for something similiar... hm...

500HP? Jesus Christ. What's the point? 300whp in an s-chassis is FAST. 400whp is crazy. 500whp is just uncontrollable. My friends SR made 444whp and he has no traction til 4th and he has 265s in the rear and a Nismo 1.5way LSD. But in any event, I would start to look at a GT3076R if you want THAT much power. And 400HP out of a .86 A/R 2871R is pushing it. You'd be lucky to hit it with the CA. Not to bag on Zilvia, but if you want some CA18 insight, hit up the CA18 forums on NICO http://forums.nicoclub.com/zeroforum/126 You can get a lot more CA specific info there.

whats the point ? 1-fun, 2-fun, 3-fun, :)

ok but seriously, because I want to try. thats all :)

thanks for url.
