What makes you so sure your used 9 turbo is going to hold up so much better than your 8 turbo? Unless you're rebuilding it it's 50/50.

 

I feel like an OEM turbo will always be more reliable than non OEM. You're right, it may not out live the 8 turbo I have now but it will out perform it.

It is going to be real tough to pick one turbo that is going to shine at both canyon carving and freeway driving, especially on your stock 2.0L motor. You are basically wishing for two totally different compressor maps. This is the search for the Holy Grail: fast spool and big topend. The state of the art is constantly improving, but....

For example, on that long, rolling stretch of Warren Freeway North-bound, between I-580 and Hwy 24 you'd ideally want an EF-4, or a Black running 28 PSI+ on Ethanol. By contrast, for being quick on Redwood Rd. between Moraga and Castro Valley ideally you'll want some smallish, ultra-spooling 16G variant preferably with a BB centersection. For this last section of canyon road, I would probably do yeah, something like a HKS GTII 7460R, BB FP HTA 71/9.8, or a BBK-Lite BB, or an EF-1/9.8, or even the factory JDM VIII RS turbo which is basically the TiAl TME turbo configured with a 9.8 housing.

That Rewood Road is sure nice but it's hyper-squirrely, and there are only a couple stretches where maybe you could touch 80-85 mph in that canyon. If a turbo doesn't spool right now, the bikes will walk you out of the corners. Well, the bikes are going to leave you anyway. But, in that canyon you gotta spool right now and have soft compounds as well.

Personally, the only real basis of comparison that I have is not in an Evo. But, I can tell you that a totally stock Audi 2.7tt (stock turbos) vs. the same car with larger RS6 turbos and Meth...the stock turboed car is quicker than the same car with larger turbos and meth through most sections of Redwood Road. Of course, on the freeway it would be a different story.

Sorry for the divergent OT and back to reality and your original question: That IX turbo for $200 installed is a good deal. Run it on a good switchable E-85/91 tune. Of course, you'll have to be readjusting the boost level with your MBC everytime that you switch maps.

 

True, which is why dropping the $70 on a boost solenoid and ECU boost control is so worth it

 

to be more specific. there arent many peopl ewho ran evo 8 turbo on e85. but there have been several threads were the power goes well over 400/400 on stock block.

the 9 turbo upgrade is a waste on e85. send it off for upgrade and sell it for a profit.

375/375 is a cakewalk on 8 turbo on e85

 

^What he said. I personally made 352/354 on a Mustang Dyno with the 9.8cm turbo and just FMIC, cams, TBE, open filter and supporting fuel mods on E85 at 30 psi, which could easily 400/400 on a Dynojet.

 

Huh, Uuri, I guess this means that you finally got your hot-wired pump working! Now I expect a ride in that beastie.

 

Thank you for your opinion. You know, redwood is pretty much the only place I push my car now that I'm really thinking about it. I used to ride my R1 through redwood almost every weekend so I know the road very well. Freeway's are just too high profile around here I think.

In terms of driving redwood, you are absolutely right in that I need spool right now to have any fun . I think that I will be very happy with my 9/e85 setup. Compromising virtually no spool but power everywhere. I think it will out shine the hta 73 on pump all day (at least through redwood rd.)

Already planning to drop my MBC for the solenoid, thanks for the heads up though.

If I had a wonderfully performing 8 turbo you're probably right. However, last time I was tuned the tuner said my turbo wasn't holding boost like it should. The taper was very significant to redline. This is what was holding me back. So, with that in mind, the 9 turbo with a brand new 18 psi WGA should hold boost alot better. Thanks for your opinion though.

 

Not I be off topic but I've only herd bits and pieces what is the FP white is it smaller then the green but bigger then stock?

 

We are not talking about the classic fp white, we are talking about the hta 71. Someone correct me if I'm wrong but I believe it came out about 1 year ago.
I believe the only difference between the 73 and 71 hta is the size of the compressor wheel. The 71 flows like 51 lb./min the 73 (green) flows like 53 lb./min.

 

Ahhh thank you sir I've only heard of the FP white like once before and never knew what it really was in comperision to the other 3

 

You now are confusing two different turbo's. The fp white is a different turbo all together. The FP white is marginally better than the stock 9 turbo. They made it a long time ago.

The new HTA 71 on the other hand is what we have been referring to in this thread. It is a $650 dollar upgrade from the 9 turbo and flows 51 lb./min. It is almost comparable to the HTA 73(green). Hope this makes more sense to you now.

 

I've had both a white and now the 71. I like to keep my turbo minimal upgrade over stock.

The hta 71 is perfect if I get the down time I want to have it rebuilt and clipped.

I virtual dyno 430-450 hp dj mode with s-2 cams skunk 2 ported manifold by STM . 23-24 psi tapering to 20

Oh yeah 93 pump too

 

Buy the $200 IX turbo, send it in for 71Hta($750) as a core ($100) and you save $550 for a new 71HTA. This is the most cost effective upgrade if you have a IX turbo laying around. You don't need the fp oil line,84mm cover, or upgraded WG(Helps hold more boost, but isnt required). I made 470/460 on a MD with a basic 71Hta on a built 2.0 @34psi/E85. Sold this turbo to a buddy with a basic mods that made around 410@30psi/E85 on the same MD dyno.
