evo3 16g or td05 18g

[skinnypimp]

well i'm about to upgrade from my 14b, and i need some inputs on both turbos. i'll be running 550's, safc and greddy 24r fmic, all the rest of my mods are in my profile. let me know which one you'll put on and why, thanks

If you want opinions i would get a t3/t4 50 trim...All around awesome turbo. Just my .02.

EvoIII is almost pretty much like a 18g so i would shy away from that. The turbos you could look at are the EvoIII, AGP 50trim, or the Bullseye-Power TO4B Vtrim or the TO4B H3. These turbos are very streetable with the H3 capable of around 500+Hp. If your on a tight budget then i would say get the EvoIII or the Vtrim since they almost come out to the same price. Just make sure you have all the supporting mods for it

 

[MNGSX]

TO4b Vtrim> than above turbos.

How's the spool on those T04B's compared to say an 18G?

 

[RavenX]

15-20psi by 3500-4000rpms on the TO4B Vtrim i have no idea on the 18g but wouldn't doubt it if it was around the same area

What 18g?

Which turbine wheeel and housing, clipped not clipped... etc....

Honestly It probably spools sooner.

Alot of thought went into the bullseye turbine housings... Not as nice as the FP30 but still better than the PTE and mitsu housings...

 

[doug]

What 18g?

TD05H 18G wheels but in a TD06 comp housing. Ported turbine housing, not clipped.

 

[MNGSX]

7cm2 ?


Probably close but the 18g w/o clipping will get out classed on the top end pretty hard.

 

[DSMnewbi]

18g.. All the lag of a 20g with the power of a 16g :laugh:

 

[doug]

Yes, 7 cm.

And newbi, I have noticed NO spool difference between this and the 16G that it replaced, so shut up.

Classic!

When I have time I'll figure it out...

I think it will be close due to the on center design of the B-eye housing and some of its other attributes (nozzle design).

I found the comp side for both... I wish I had the stats on the turbine wheels... Off the top of my head I think the turbine housing design plus garrets higher efficiency turbine wheel will make up alot for the larger size of the T04B's compressor side. On the info I have about the same but with more power..

Clipped 18g's are the ones that almost keep up with 20gs... Unclipped 18gs spool faster than the clipped ones..

18G EDIT WRONG

all depends on application, from personal experiance the evo III 16g spools to full boost round 3k and still holds it to readline, it can allso push ~39 lbs from my experiance, ~23psi which is about all you'd want to run on pump gas. i'm not sure what this turbo can do on race, but i can't wait to find out. great for ~400hp on the stree for the price. it's also watercooled which makes it cheaper in the long run as an air to oil cooler isn't necissary like some larger turbos require.

because you have a 14b you won't have to worry about the jpipe and all that crap, so the evo 16g is an easy bolt on.

the only downside is the torque curve falls off a bit faster than some of the larger turbo's mentioned on here, which is to be expected. but the turbo is capable of high 11's in the 1/4, if your looking for better than that then i would suggest the other turbo's mentioned on here.

 

[MNGSX]

When its short route FMIC time the straight down comp housing will be helpfull...

Pros and cons to each turbo.....

 

[skinnypimp]

well i went over to look at the turbo today, it's a 20g brand new and he wants $500 for it. it's internally gated and my boy said it's clipped.

 

[MNGSX]

A clipped 20g will be super lag fest for a street car..

 

[psychlow]

FYI - clipping kills turbine wheel efficiency.

Clipping = bad. If you want more top-end, buy a turbo with a larger turbine wheel or a larger turbine housing.

MNGSX-- what's a TD04H 18T?

 

[MNGSX]

I guess they dont have an 18g on here

[pboglio]

That map seems odd. A compressor wheel as big as an 18g seems out of place spinning at 170,000 rpm when the same exducer on the 20g wheel isn't cracking 130,000 rpm and the small 16g spins around 156,000 rpm. That rpm is indicative of a compressor the size of a 13g, IMHO.

 

[MNGSX]

I think you are right..... But It's not a 13G map because this is..

http://not2fast.com/turbo/maps/td04-13g.gif

Anyone have a definate 18G map?

 

[psychlow]

That rpm is indicative of a compressor the size of a 13g, IMHO.

Perhaps that's because they share the same size compressor housing?

I also don't agree that an 18T is the same (or similar to) an 18G. A TD04(H) is a very small compressor housing.

The FP18T is an upgrade for WRX drivers -

FP's WRX test pilots have reported that the turbo provides a substantial increase in mid range and top end power, while sacrificing very little in the boost response department. Initial dyno tests yielded 247hp to the wheels at 15.5psi. At that level, the power output is approaching the limits of the stock fuel system. Larger power gains are possible with an upgraded fuel system and higher boost levels.

According to internet sources, a REAL TD05H-18G map was never relased by MHI.

EVOIII 16g rated around 575-580 cfm @ 14.7 psi (from map), 18G rated at 600 cfm @ 14.7 psi (Forced Perf). EVO spools as fast as my T28, I've not heard great things about the 18G spool. Price, EVOIII 16g $565, 18G $699 with NO water cooling from FP. An EVOIII 16g has a good resale price if you don't like it. Guys are running some crazy trap speeds on the EVO turbo, I'd buy it in a heart beat.
