Quote »i read through the whole post and didn't find this, but what about 60 trim with .63 a/r.. is that going to be too big too??[/quote] Depends on what application you're using it for. Everyday driving: it's okay if you're patient for boost . Spurt racing: You're toast because of lag, but it's pretty much the closest combination for some good dyno power and some good track performance. It will lag between gearshifts, but you can use N20 to fill in the blanks. Like I said, this motor is not a low end monster and does not have the intestinal fortitude to spin decent size turbos under 4,000rpm even if the timing is advanced at certain rpm points.

What turbo!!!

I use both a 60-1 and T3/T04E stage III. Both started out with .63 exhaust housings and .60 A/R with .57 trim, but I complained to my turbo supplier that my engine was falling on it's face between gearshifts even with my timing advanced at certain rpm levels to prevent it and he recommended that I change to a .48 back housing. And every since then, my g/f's car is more awake, responsive, and still has ridiculous top end end power to row through the sweet gears. I mean @7500 rpm in 3rd gear, I'm watching the speedometer race past 120mph; but it moves so quickly on the highway, I can't really stretch it out without compromising safety. For years I've fought with the .63 back housing and all the while I had been shooting myself in the foot. if you're going to just dyno test, then strap on your .63 housing, but if you're going for some street racing or heading to the track, strap on the .48 and watch the CA do what it do "Show-off":) .
rememerb the 50 trim and 57 trim To4E are VERY different. when i was shopping for a turbo everyone told me to stay away from the 57 and go with the 50 trim,
the GT28R is NOT a GT25R, the GT25R out perfroms the GT28R anyday... thus the GT25R spooling a little alter than the GT28R.
Why would you not reccomend the .63 turbine housing D?
everyone that has been using it on 1.8 GSR motors, SR's, 1.8 Miatas , 3sgte's etc all have had marvelous results using the .63 stage III turbine housing. what rpm was the engine dropping to inbetween shifts? below 4500rpm?? hmmm/.

Quote »Why would you not reccomend the .63 turbine housing D?[/quote] Most of the guys here have not a clue as to how their engines will perform with a big turbo like that and from listening to them, they all want something they can get in and enjoy, not have to wait for power. The .63 will unfortunately, give you that momentary lag that most street performers don't like. The 3SGTE is a bigger motor, so it has enough exhaust pulses to excite a turbo with .63 housing, I can't say for the others, but displacement wise, I know the GSR is a tad bit bigger than the CA18. I can't comment on the GT series because I'm not accustomed to them. I have been offered to use a Gt3037 on my car in place of the 60-1, but I declined for right now.
If you guys don't mind on seeing your power around 4400ish-4700ish then I say get the T3/T4 turbo with the .63 housing. Once again, we can't compare other engines and they way they handle a specific turbo as opposed to the CA18DET. It's just a different kind of engine, that has it's likes and dislikes that are not inline with other engines. Question would be and like float says, what are you trying to do with your motor. If you want to chase dyno figures and try and out perform the SR gang, then you should be looking at a 62-1 with a .82 back housing. Very laggy, but will get you impressive #s somewhere in the 5000ish rpm range. If you want a good highway turbo for the CA18DET a T3/T04b or e stage 1-3 will suffice, but the 60-1 is superior for straight-up 100+mph bursts. If you want flexibility and street perfromance as well as a strip runner, the go with the T3/T04E stage III with a .48 back housing and you'll thank me later. Put the .63 housing on and let me know the difference (though I already know it).

won't retarding your timing increase your EGTs and spool faster ?
turbonetics 50trim is the hot setup for 4cyl... is that the comp wheel you're referring to and not the garret 50 ?jgstools.com claimed 375whp from a miata 1.8 running a t04b/s-trim/0.48/stage1 (std t3 turbine wheel).
I'd think a stage2 or either one clipped would give u even a bit more topend.Some mitsu guys clipped their turbine wheels and gained some topend as expected, but swore their spoolup *improved* too. Yep, thats no typo. I'm thinking there may be a fine line where the benefits of reduced turbine wheel wt and more flow thru the wheel, outweigh the lesser fin area for the exhaust gasses to turn - hope that make sense.Anyway, when u see these guys are experienced DSMers with lo 12/ hi 11sec street cars, its worth a listen... besides they have nothing to sell.
