I have the comparison chart with me, having to use my laptop in another department for actual work right now unfortunately. My TD04 stg2 graph's low end torque is a lot more "punchier" than yours.

Here's my little WIP. I could have smoothed out the stg2 tune I'm sure, but that's water under the bridge at this point . I'm still working on pushing the torque curve to the left, seeing what I can get out of it total. It looks to be spooling up as expected, a few hundred rpms less than the TD04. This is a Kinugawa T518z-16g, basically a Big 16G.

Thanks to Brad and vDyno BTW, really enjoy comparing logs graphically rather than just poring over the spreadsheets. Makes it easy for stuff like this.

To maybe put it in perspective how the "lag" will be with a turbo like this. I have a basic Vf-34 set up with ebcs on my 04 wrx and the torque curve 2k to 3k on the dyno was the same td04 stage 2 to Vf (after protune). Starting at about ~150 torque on the graph and then going to about 200 at 3k. Difference being that the vf continues on to about 240 wtq by 3500 and the TD04 just died. Do I think it feels laggier? Sure, but I think its just because peak torque is a lot stronger and comes on later. I'm sure it is faster all around though.

Thanks, that's good info. As long as I won't lose lower end response because of lag, the higher end torque would be nice.

ogboot - that definitely looks like more of a kick than my graph. Thanks for posting it.

I'm still thinking the vf48 might be my best option for good response without going much over the 300whp that my 03 tranny might not like. Probably with 750's for a bit of room to grow if I change my mind later.

750's will allow enough room for E85, which would liven things up

<-- dw 750's for that reason!

Take my graph with a grain of salt, I've shifted my boost target up an rpm cell since then. I'm also using an ebcs on both runs.

i have a old cobb stg 2 reflash and i put a 16gxt in my 03 bugeye. i need to up grade to 750's and a new tune .but i did a few pulls at @15psi and the power was crazy ,the best part is the mid and top end ,no drop off,cant wait to retune it with the 750's and crank up the boost to 19-20 psi give my new wisecos a work out....one thing i will say in first and second you better be ready to shift as 7500 come in a hurry full boost is in by 3500 -4000 depending on which gear you in .great med turbo ,they should have made the car with that one ...getting better MPG too ,28.5 with off boost highway driving .

Be careful doing that until you get your tune, larger turbo will be less forgiving...

I noticed your posted graph is with smoothing:5. I usually only set smoothing to 1, unless the software picks up a lot of deviation cause of the road then i'll turn it up more. Generally the more smoothing the less HP/TQ it reports as it's removing the peaks and valleys.

Why did Blouch stop making the 16g, that turbo seemed to sell well for 2.0L guys who wanted a new turbo rather than playing with a used VF and the cracking issues they have.

If I had to guess... more MFGs have the tools/equipment available to do the 16G and lower end stuff, so they've moved on to the higher end turbos where there's still more margin to be had? Just speculation.

I had my VF22 PnP by grimmspeed and it's great on my 04 rex. The turbo pulls hard and does not die out so if you know how to drive your car lag is not an issue when your in the right gear. My tuner was very impressed with our 3rd gear pull road tuning. Tuned 21psi...estimated 290awhp at 4,800'. 2nd-3rd would put sti's in the rear view.

To the OP, here was my thread with the two charts. Sorry, I fudged the numbers in my original post. Its 115wtq at 2500 and then about 155 at 3000. In any case, about the same each way. Like I said, it does feel like it takes a little more effort in the low end. That is probably just butt dyno, because if you look at the two graphs they are almost identical until the td04 hits peak torque. The EBCS makes boost response much faster on and off the throttle as well.

I would say get a used vf series turbo. Some 565cc injectors and a fuel pump and your on your way to 280whp. (by nasioc standards lol)

Oh and my PE1818 Hits full boost at like 4900rpm (stock boost control) but the power is still there through the rest of the powerband just as much as the td04 and it hits HARD up top 4900-7000rpm

You have it correct, the 68hta did not meet most expectations (read:hype). It was supposed to eclipse the evoIII on the 2L, but had late spool and average power compared to other available options. For your goals it's not an option really.

ok as Ezil started this with a question of what turbo to use, me I'm going with the Blouch td05h 16gxt, got the STi TMIC, PE 850cc injectors, walbro 255, Cobb 3port EBCS. Already rebuilt heads, engine, trans(4EAT[bad back can't shift a stick anymore]), Tanabe bellmouth 3" TBE, Cobb SF intake with box, Cobb AP, and will have it tuned when I install the 3port. if I did my homework right I should hit 350chp with ease and keep it a semi-safe DD. Just really hoping to have something fun and stock looking, don't want anyone to know what I have under the hood.

any suggestions on what else I may need would help.

I feel like the 16g-xtr could be lumped into the same category as the hta68. Im yet to see a plot of the xtr on E85... would be interested in the results.

i think for a street car, a bb turbo would rock as the transitory throttle response would be so much faster....and if things get tuned right, lag would be almost nothing

the small P&P 16g i had on my 2.0 ROCKED....on e85 it woulda REALLY ROCKED.....make it bb center cartridge and

The 68hta has a significantly larger compressor wheel.

And I agree with the pnp 16g. My 16g setup was very fun.

Yeah that's a lot of injector for the 2L. I went with 750cc because I wanted the headroom for E85. Who knows, maybe you got a killer deal on them or something?

That was my initial thought for my setup.

Has anyone done a P&P on a vf48? I'd be curious to know how that compares.

I was very interested in the 16g xtr when it was first mentioned, but like others, I'm still not seeing that it has the kind of response down low that I'd want for a DD.

Honestly, it seems a 7cm 18g wouldn't be that far off on response, similar top end, for a lot less $.

the bb center still has me wondering though....
