bump for a great thread. I am asking myself the same questions. I am leaning towards the 20G-9. Where can I buy one and for how much?

 

Way too early to tell. Youre going to have to give it a few months at least to see what the deal is with these new evo 9 and 20G-9 turbos.

To date, I havnt read about a single evo 9 turbo bolted on to an 8. And only DB has tested the 20G-9. Thats not enough information.

 

Good info guys! I just want to find out how the EVO9 20G compares to the TME, inasmuch as spool, and HP. I guess we will have to wait. I think they are pretty close, and If one got a TME or a 9 20G, they would be comparable. David does alot of research on stuff, and I appreciate that.

So if a 9 20G will spank a 35R from a roll, I deduce that a TME could also. Or is my head up my butt??!

 

DB said he could also install a TiAl wheel on the new 20g-9 for an extra 2 or 3 hundred if you want the extra spool.

According to davids "from a roll thread" both the 20g-9 and a stock 10.5 evo 8 turbo charger would beat a GT35R in 3rd gear starting at lower rpm....with the 20g-9 being the fastest. So yes, a full pull through 3rd, the TME would win.

 

Great info! I have the Ti/Al now. in the TME. I am spooling quick as it is, so I dont know how much quicker, and spoolier I can get. The turbos listed above, The 20g-9/and the 10.5 Evo 8 turbo, is not a TME turbo. I believe the stock evo8 WITH the 10.5 hotside, is the same as the TME, EXCEPT the TME has the Ti/Al internals for quicker spool up.

So the TME's quicker spool-up gets you to the HP you need QUICKER than the 10.5 evo8 turbo, but NOT AS FAST as the 20g-9 correct? And if you get to the HP quicker with the 20g-9, is there more HP under the "bell-curve" on a Dyno graph?

Geeeze, That is the most abbreviated letters I ever put in one paragraph!(since I left the Army) I need to get the Tums!

 

As a side note Mercenary3, I was raised in West Bloomfield Mich. heard of it? Ok, back to my dilema

 

Smokedmustang-you and I are in the same boat. I can't go huge turbo becaust the lag will kill me in the cones. I need the best HP/TQ gain with least sacrifice in spool. These are the exact choices I'm looking at, plus the HKS 2835

 

I guess we sit back bro, and wait for someone who has the answer! I am with you on this.

 

Would it be possible to piece together an evo 9/tme hybrid turbo? Like an evo 9 turbo with the ti/al internals from a 6.5 tme.....

 

3rd gear roll on from 35mph because the GT35R is not in its sweet spot , so not a real race .

 

The 9-20G (or TME) supposed to be the ideal setup for our cars - most fun and not stricktly for drag racing. No lag, very linear and doesnt run out of breath - best of all worlds. We'll have to wait and see.

I think stock injectors can't support it though, and maybe TB and IM porting might get you the best out it with your other mods.

 

Hey...your on 502streetscene.net.

I'm in the same boat as you. I want a good pump gas and fast spooling turbo. I believe the EVO 8 20G went 11.2 @ 124 mph on one of DB's EVO's with race gas. I'm sure that is still a 11 sec car on pump gas....or I'd like to think. Dave did report some surging issues with the EVO 8 20G though. DB did say the EVO 9 20G is a little laggier than the stock turbo, but you can upgrade the internals to a TME.

Now the EVO 9 20G is on another one his EVO's. The surging is gone as you can see on the vid he posted in one of his threads. He has done alot of comparisons witht he turbo. On pump gas a stroked 2.3L GT35R EVO made 45-50 mph hp than the EVO 9 20G and the EVO 20G made like 30 lbs more torque. On another test he showed the spooling and accelerating characteristics on the same cars (I think). The EVO 9 20G equiped car went from 35-75 mph 2.15 sec. faster than the 35R car.

I honestly wouldn't put a 35R on my car unless I'm going to completely build my car for it. To me, there isn't a point to having a big turbo is your sitting on the stock or near stock redline. Your not even close to what that turbo is gonna do with the stock rev limiter.

If I can bolt a EVO 9 20G on my car, upgrade my injectors, do a couple other things, and make about 380-400 whp on 93 oct WITHOUT alky or meth injection I'd say the EVO9 20G would be worth the money. I'm gonna be patient and see how everything goes with the guys that already purchased the EVO 9 20G and make my decision. If the numbers aren't that great and I don't think they are worth the money, then I'll just stick with upgrading to the 10.5 hotside and just deal with having a snappy and fast spooling slow car.

 

Thanks Corey (My "family Member" from 502 street scene ) That is great info. I am leaning away from the GT35R because I want to do more road-racing as opposed to Drag racing. And I want to see if there is any difference in numbers and spool-up between the TME and the 9-20g. I think they are close enough to call it a "wash".

 

Have you considered the WR or a 3071 turbo? I have the WR with alky, and it spools like crazy.

 

I have thought about it, but am trying to decide if the price is worth the gains. The TME is a sweet turbo, and I dont know which ones I can Just "bolt up" to my manifold. I dont want to loose the quick spool up, nor change turbos for 10-15 AWHP gains. I dont think that would be a noticable "seat of the pants" difference.

You have the WR, but have you tried a TME with alk? if so, could you give the difference as you see it? You live close, maybe we should do a "seat of the Pants" test! Thanks for the input.
