BEP made a 8cm hotside for the td05.What is the housing? Is it for holset?
Only about 5 or 7 of which are actual Evo III's running 10-second passes. To make any 16G go 10's it takes an exceptional build, a great tune, good fuel, and an amazing driver...you're making it seem like anyone can bolt a 16G on their car and drive down the track to a 10-second pass which is quite misleading. If that were the case the 68HTA, Green, Red, Black, 3052, and 3582 would never have been created.Many EIII 16g can run 10's... It's all about the tune and mods!

Yea I was looking at the fp but a buddy told me at the evo 3 is 7cm housing and would match with the manifold while the fp is a 8cm. Idk what kind of difference that makes
you and I must've read that at the exact same time.I can't even believe this is a thing anymore... I feel like it's been harped on since I joined in 02 .
I PERSONALLY had every supporting mod on my 2g - FP2 cams, ECMLink, injectors, pump, 3" exhaust, Evo III IM, FMIC - and had Road Race Engineering professionally tune it and put down 260awhp / 280tq. Stock 7-bolt s16 RRE Tooned...but saying a 16g produces 250 hp is not accurate information unless you are talking about bolting it on with no mods and no tune.
Now I know you're blowing smoke....That goal (referring to 250hp) can be reached on a T25 with supporting mods and just AFR's changed to 11.0.
I did go back through my build thread quick, I didn't have the FP2 cams when I dyno'd the 16g but did install them prior to dyno'ing the car with the HTA68 at low boost on 91 which would account for the 90hp increase but would also explain the laggy(er) spool up. Even so, this about as close of a comparison we're going to get around here with these two turbo's and even with the entire DSM community snagging these TF06/8cm HTA68's there's absolutely no data out there.but that is a 5h turbine in a 7cm housing? the new 68s are 9 blade TF06 in an 8cm.
dont know if we are supposed to believe 68 is worth 90hp over the 16g. something is off there.
No you can just spools a little slower than the 16g, but has more top end power.
I hold 22psi to redline on my billet 16g on e85 but the fp 68 hta can hold more.
Notice any big differences with that billet wheel? Thought about switching mine out but didn't feel I would net any gains for the hassle.
Still have a couple weeks until my dyno tune. Curious to see what I can pull out of my evo3 on e85
I don't have any comparisons between the billet vs cast wheel. But from what I read it really doesn't add any gains unless it's angled or degreed different from the stock cast design.
Earlier you were trying to give me a hard time comparing an older td05h/7cm HTA68 to the redesigned tf06/8cm HTA68, now you're including the "countless" 400whp E85 16g builds from EvoM?gofer, there are a dozen good back to back 68 only swaps on the evolutionm forums. countless have made 400whp e85 on the 16g. the hta 68 (called 71hta/68hta/white for evo 8/9 but exact same wheel size) nets 450whp e85. for pump gas swaps it nets 25whp. the original non inflated flow rates given by FP also best support the flow differences. 42lb for evo 16g and 47lbs for 68hta.
This post is about swapping from a td05/7cm 16g to a HTA68 on a DSM, not a td05hr in a 9.8cm/10.5cm hotside on a completely different platform. I'm not going to try and stand toe to toe with you getting into a turbo discussion because you've probably forgotten more about turbo specs than I'll ever know however, bringing up spool/power expectations from what an Evo can do on the stock Evo VIII/IX 16g's is completely irrelevant here.Even so, this about as close of a comparison we're going to get around here with these two turbo's and even with the entire DSM community snagging these TF06/8cm HTA68's there's absolutely no data out there.
You're probably going to run into surge issues at some point in your powerband. A 16G was never designed to have a 6cm2 housing...especially one being used in a performance situation. Perhaps with a turbine upgrade, but then you're shooting yourself in the foot if you're going for spool. I don't really recommend them for any 16G outside of maybe a Small 16G being used at 18psi or below on a daily driver.I'm going to try a e3 16g in a 6cm housing with a large external. Try the compound idea out with it, in a sense. Vent the excess gas around the turbine, but keep a small housing to keep the spool.
I hope it works.
...if you can find those countless "400whp e85 on the 16g" threads from EvoM comparing the turbo's in question, i.e., Evo III 16g (td05h) vs HTA68 on a DSM please post them since it would help answer the OP's question and add some value to this discussion.
