Cant Decide, 16g or 20g Opinions please.....

[kevint427]

I cannot really decide which to go with. The 20 g looks a little more convenient on install for my setup, but do I really want to go that big? I am looking for a daily driven 20psi and really no higher even when racing. I have everything ready to go, SAFC, AVCR, im going to wait on fuel pump and injectors till i am sure of a size, BIG fmic installed, downpipe, exhaust all 3", o2 housing with wastegate dump tube, greddy bov, hard ic pipes and i have an ebay turbo manifold waiting for the new turbo. so you can see where i stand as of now with a siezed t25. it has never been so slow. I am just curious as to what everyone thinks.

If you do a search you will find these 2 turbos have been compared numerous times. It really depends what your looking for while the evoIII is a great turbo & lots of fun on the street, speaking from personal experience I'd go with the 20g. The reason being you always want to go bigger after awhile. You will be limited to 650 with the SAFC piggyback system unless you run an eprom chip to compensate for larger injectors (which you should be able to do as you have a 95 and probably have an eprom ecu) or step up to DSMLink.

thanks a lot man. im doing more research about it right now, however you did remind me that once you are used to something it gets boring and then you need bigger and better. what happens when the 20g isnt big enough after awhile? ! thanks man!

Is there a reason why you want this 20psi max from a turbo? What are you goals?

50 trim, 60 trim, GT35R, the list goes on . Before I bought the evoIII I thought it would be more then enough & it would be the most amount of lag I would want to put up with. Let me tell you lag is defently overrated, anything that spools in the 3000's will be extremely street friendly, currently I see 20 psi with the evoIII ~3400 rpms. It kept me happy for 2 summers and I've got about the most out of it you will see on pump gas (without water injection & a built motor). Has been fun, makes jokes of most mustangs & other v8's, can take most corvettes, etc. Personally I think I will probably end up with a PTE dual ball bearing 50 trim for next summer.

16g would be easier,
20g would be more fun...

I say 20g

The 16g wont be much easier in my eyes. If your going to be running pump gas, I would go with the 20g. It has larger housing meaning it doesnt heat the compressed air as much as a 16g meaning less knock and more pump gas friendly. You would beable to make way more power on pump with the 20g. 20g all the way

 

[1g_tsi_awd]

Good point I suppose.

Why do you say a 16g would be easier? They both aren't direct bolt on's, as far as that goes & they both pretty much require the same type of supporting mods, just with the 16g they won't need to be as "large" (eg injectors) but the cost of supporting mods will be pretty much the same. Though I too would say 20g, go with the TD05 turbine housing if you want quicker spool or step up to the TD06 housing to get better top end at the expense of some extra lag.

I was in a similiar situation before I got my turbo upgraded. Previously I had a S16G and liked it for about a month or two. So it was off to the forums to see what other people were running and thinking. I was considering an evo III 16g, 20g, 50trim, and a gt30r. After talking to a few people I trust, they were telling me that a 20g is very expensive and if i were to get that, it'd be better to just get a 50 trim. I actually really wanted the gt30r, but the cost to install all the supporting mods added up real quick.

I opted for the PTE 50 trim (non-ball bearing) for now and I'm enjoying it a lot. If you don't want to boost that much, you could always back it off w/ a boost controller.

If you want your car to spool up quick and have make it more of a cornering car, maybe the EIII16G would be you pick, but if you want top end power and some crazy pull on pump gas, the 50 trim would be my pick over the 20G.

Good luck

I highly reccomend not going with the tdo5 housing over the tdo6. I know somerun running a 20g with the tdo5 housing and its not that impressive. Evo 16g's have put just as much power as a "bastard 20g". Even with the tdo6 housing it should still see full boost by 4000rpms. If you can afford it go with a ball bearing 50 trim like stated above they spool very fast for how large they are.

There is no way you searched. There are more than 400 threads on 16g vs. 20g turbos.
