Lets talk about a reworked stock turbo.

Lets just say Ive got turbos on my mind.... and I havent heard enough about bigger wheels, port and polishs, larger wastegates and all that is possible on what we already have.

A member here... cmescoot... has got one done by modern performance inc, I think. CPE has been talking about doing one. I know some other members have been in communication about it with some folks. And Ive got guys local that could probably do the job.....

Who wants to speak first? Whats possible here?

I would be VERY interested in this option.................... so after you ladies gossip, could you share the wealth of info?











j/k about the "ladies and "gossip" comment. Couldn't resist :)
 
Yeah, Id like to hear too.
A bigger turbo would be cooler. I know daily driving a turbo'd car with fast spool is fun,but its also fun for there to be a bit of lag, then when you get on it you can really feel a difference and you can just rip it.

amen... I think with a tubular manifold, on the gt3071, we could only lose a couple hundred rpm spool over the stock setup. Just enough for traction and dd, without making it a laggy slut.

Modern Performance who did cmescoots turbo is claiming that its now efficient up to 400 hp. Does this seem possible? Thats like 80-90 hp gain... and seems unreasonable.
 
18 minutes just passed from the time I mentioned that a vendor is claiming a reworked stock turbo, available now.... could make up to 400 hp.... and no responses?

somebody say wow or bulls*** or something godammit

Well, typically from what I've heard, whatever they do to rework it usually results in a trade of low end for high end.

I kinda doubt getting 400hp out of the stocker.

Well, I am sure it is possible to make enough power to find the weakest link in the driveline and I imagine it is somewhere under 400hp.(weakest)

Probably facing an FWD limitation as well.

That said, I hope somebody does it!(drive2)

Modern Performance's turbo work is very good. We've got a turbo coming to us thanks to mrlilguy which we will be re-working in a similar vein.
 
I wish i could show you a slip. Unfortunately, I am still waiting for my manifold and fuel pump from PG. (I think I share the same anxiety with many here).
With all of my mods and a good tune, my main concern is going to be the rods....and of course the clutch. From what I have been told by Jordan at CP-E and Nick at Modern Performance Inc, my "new" snail will only have about a 400rpm lag and will be capable of just over 400hp. I dont think I will push that number until the new rods are in for obvious reasons. The methanol will help preserve my motor but lets face it...on our fwd car, 400 will be too much anyway. Again, my car has been on my lift since early october and I wont have any solid numbers until I head to Atlanta for my tune, but I hope to give any other speed3's a run for their money. I figure if Jordan refered me to Modern Performance (we all consider Jordan as the "Yoda" of the speed3) then the work must be top notch. I would love to hear all logical feedback and bench racing tips while I wait indefinetely for my parts to come in.
I look forward to hearing back from you.

This seems to be the logical next step. I'm sure sure I would trade some on the bottom to gain some breathing up top. Very interested in the progress you all make on this. But I'll have to agree the mechanical limits at 400hp will rear their ugly heads. Best luck Share when ready please Ps very late, Wow and bulls***

When I was younger (10 or 12) my brother and I had a 4minute light saber fight routine all over the living room, jumping off of couches and etc. Those were the days.

My feeling on turbos at this point:

I'm going bigger, no doubt about it. Ken has something in mind for the stocker I sent him and that is awesome. I wouldn't mind finding something that utilizes the stock downpipe flange, because it would be cheaper and more practical for all of the guys that already have aftermarket downpipes, and thats exactly what Ken at PG has in mind too (as far as I know)

I plan on getting something that can put down near 350-370whp with all supporting mods (I/C, dp/midpipe, intake) at under 22psi or so. I don't mind lag at all, I'd prefer it. As palerider said, the lag is actually a nice gift to the tires. I just replaced my potenzas (got in may 07) at christmas time 2007. they were bald. Now my 912 all seasons aren't lookin good in the front either. I drive too hard too much. The cold weather doesnt help them stick either, instead they just heat up and burn rubber on top of the surface.

Anyways, I'm sold on the 3071r, but don't wanna limit myself for the future, so I think the 3076r would be a better choice for me. Maybe 400rpm later spool when I've got the 3" DP and PG exhaust manifold? I plan on getting a 1949-1953 Chevrolet Deluxe Cab 3100 truck out of school for a daily, and have the mspeed as the grocery getter and night time fun car.

So a spool time of 4k or so? I can live with that. Pushing under 18psi, with no map clamp, even better, less fooling of the ECU.

The top end of the power band will be taken care of eventually (throttle plate closing) by Cobb, CP-E, Xede ProCede system maybe, or maybe what Nutari's 'standalone interest' thread has to offer, if not someone else behind the scenes at this point. I have ideas and am working with a company on my own time to try and figure out what parameters the ECU is seeing to close the throttle, to see if there is a simple fix.

Conclusion:

Bigger is better, but not 35r bigger. I think (know) the 3071r and 3076r are the best turbos available for the car at this point. If you're not going to build the bottom end, go with the 3071r. if you are, or are considering it, go with the 3076r. Both setups will be very streetable. The sucky ECU will be reprogrammed eventually (time is all thats against it), and a the fueling is fixed, and there are forged motor options out there. ATP offers these solutions with a propietary flange setup to force consumes to buy their downpipe (good marketing idea), yet it sucks at the same time. If something is to come relatively quickly with the same sized setup on a stock exhaust flange, you can bet I'll be on that.

Until then, I'm sold with ATP's 3071 or 3076r setups. (usa)
