Ideal Turbo Size

Hi Guys.

I am new to the forum. And find this forum very interesting and helpful.

My question is what will the ideal size turbo be on my CA18DET 200SX S13, if i was to upgrade the turbo with a bigger one?

And will still fit the stock manifold? 😮

Ideal for quick spool up and a decent torque band...

GT2860RS from Garrett... That would be my first choice

and it's direct bolt on...

Engine Parts is the local Garrett distributor, last time I checked they had in stock it was like R8900

what about Garrett GT2871r - same thing with bigger compressor wheel, as far as i understand.

also available from engine parts???

i know rezlo can get, or you can try to import yourself!

I heard those turbos are quite potent. Which will be a better option though between the Garrett GT28RS (Ballbearing) and the Garrett T3/T4 (Hybrid) turbo?

I think the Garrett GT28RS will be better, and other opinions?

T3/T4 is a Danville mod... and you'll need to change your manifold, the other ones are a straight bolt on, well nearly you'll need to modify your hot pipe a little but nothing that can't be fixed with some silicon hoses.

I also heard good things of the GT2871R it spools a little later than the 60R, which is what I don't like, but it has a larger torque band which is cool.

For my personal preference I would still stick to the GT2860RS

Yes i do like the GT2860RS.
What about the GT3071R?
Or is it to big for the CA18DET? Or does it take to long to spool?

Basically which turbo will be the best between the GT2860RS and the GT3071R? For a CA18DET?

GT3071R I think has a T3 housing... not sure at all... but would guess its too big for the CA18DET... Last thing I want is full boost coming in at 5000rpm

I spoke to turbo exchange, the ballbearing turbo's are very good but he said unfortunately these turbos are not as easely repaired as normal none ballbearing turbo's, this means 1 of 2 things, either when it goes you need to buy a new one or you wait for months so they can send it over seas to be repaired......he supplied a guy with one and the guy had to replace it 3 times in about 2 months....

my opinion is rather create your own hybrit t28.t3/t3.5, parts are easily availeble so it can be fixed easily

Shame, poor Charl 😛

But I agree, why hack something then there are 100% fitting alternatives for the same price 😛

GT2876R FTW!!!! 😀

I wish I had R9000 just lying around. 🙄

With all points taken into account the T3/T4 is Danville but its damn more cheaper then a GT28RS even with the manifold and exhaust taken into account.

So yep its "danville" but so is a 1400 bakkie with a Turbo Mazda motor

just finished installing a gt28rs on my s13.did a lot of justifying on y spending R8500 on a gt2860rs was the right thing to do.after about a month i realised, finacialy it wasnt a good choice. then went out and bought it. bolted it all in but running as expected.boost comes in at around 4500rpm.only 0.5 bar.my first turbo swop so im sure i stuffed up somewhere.if anyones got any ideas why boosts comeing in so late let me know.ill keep u guys posted if it was worth it or not.

I would still rather go with the Garrett GT2860RS Turbo.
Ballbearing turbos makes more power than the hybrid turbo.

That turbo would do wonders for my sx on the 400m, because it spools soon.

P.S. It's not the size of your equipment that counts , but it's the way it performs!!!!!!!!!!!!!! 😂 😂

My choice?

GT2860RS!!!!!!!!!

The GT2860 is what I would use on that motor at sea level. AS for ball bearing reliability with the correct oil feed and quality they will outlast a journal bearing turbo considerably as there is no side thrust.

Ripped 200sx what intercooler and plumbing are you running,is your car standard besides the turbo?

hiya... are you doing any sort of boost control? or do you just have a vacuum pipe plumbed directly onto your WG actuator? Cuz that would cause what you are seeing...

I start making positive pressure by 2k rpm and will prolly have full bore by like 4k. Your turbo is quite a bit smaller so i don't think it should spool so late.

My advice would be to get a elec boost controller. That way you can set it so it keeps the wastegate completely (well more like "completely" *does the fingers thing*) shut till desired boost is reached.

I had a greddy profec on my previous setup and it made a MASSIVE difference to the manual one i had before 😉

running a SR20det with a dicktator management system, bov, rising rate regulator and a 600 200 50 chopped up truck intercooler. fitted the turbo and made up my own pipes.with standard t2.5 and intercooler was making 163kw with 0.8bar at fly-wheel.

must b an electrical 1.got a switch in car the gives an extra 0.1 bar boost. not too clued up on vacuume pipes but il try to explain how its set up. pipe comes from throttle area goes towards actuator.spilts up, one into actuator, other into boost controller, then out into air box.if that makes any sense!!!

Down here in durban my CA18DET with Big FMI and 76mm pipe is making 161.7KW @Fly And 285 NM Torque @Fly.

I am going for the Garrett GT3071 Turbo for my car.
