Does anyone know where to buy an exhaust manifold for the Ecotec that will mount a T25?
Please keep all your comments about the T25 being too small to yourself; this is just an experiment.
Thanks for the link Spotabee, but that's for a 2.2.
Know of any for the Ecotec?

oopsies. my bad. Talk to Brian at exploited. And make sure you specify that you want it in a timely manner.

I love the humor! Ive been doing a lot of work lately, mostly to get the uh "not so great" delivery times down.. A LOT. Ask some of my recent customers, theyll tell you how long its been taking to get a manifold... anywho.. ill be around here and there until im fully ready to take on the j-body performance market agian.

might that include selling quality "kit" parts separately... such as equal length manifolds, oil lines, hard pipe kits... blah blah blah?

For now im jus selling manifolds.. ill add more parts later on in time.
I dont have time right now to keep up with all the other parts for a kit like the tubing, I been workin around the clock to get my CNC mill sold and shipped out while I get a new machine in that was cheaper, and but faster.. and it can run on its own so while its cutting i can be welding or doing other things.

i'd buy your mill if i had an immediate use for it

why in gods name would you want to mount a t25 on a eco? destroked w/ lower compretion you should have no problem spooling a 16g...
I'm temped to simply refer you to the 'keep your comments to your self' line in my first post, but since you're an autocrosser Josh, I'll tell you what I'm doing here.
The T25 is a mockup to see if I can get everything running before I drop $1200 on a GT28RS, which uses the same flange. Now, before you tell me that the 28RS is also too small, let me pre-empt by letting you know that with the right choice of options, it will flow way beyond most of the T3's that people seem to like.
Yes, it will limit me in hp compared to some monster turbo. That's fine, I have no need for any more power than this will deliver. It should *easily* deliver 225hp, which is my initial target.
As an autocrosser, I'm looking for ultrafast spool time. I'm talking in the 100-200 millisecond range. The GT28RS should give me this, with the proper internal mods. Which brings me to my last point - I'm not destroking. I realise that this will have a detrimental effect on the absolute power that this engine will make safely, but I'm more interested in the low rpm gain of stock compression compared to destroked.
I've done the math, and plotted my engine curves on the compressor maps from several turbos. The T3 is not nearly as efficient as the GT28 is on the Eco. More efficiency will give me longer before heat-soak. And for lapping days (and I'm thinking of running regional GT test and tune days next year - wheel to wheel) that will be beneficial.
I'd welcome your comments and questions about this approach.
In the spirit of trying to foster some serious discussion here on the .org, comments like, "Man, my T3/T04e will SMOKE your T28" will be ignored.
GT28RS is a bad ass turbo!

You can also get the GT28RS with a T3 flange turbine housing. I was just looking at that or the GT30R

Don't the vast majority of the Garrett GT turbos come with T3 flanges?

Yes they do, so I cant figure why you wouldnt want to go that route instead of the t25.
T25 has lower volume exhaust housing which = faster spool up.

I think your approach is logical and perfect for your application. The t25 will spool in no time. Should easily make the power your looking for.

I'm sorry Brian but... GT30R or GT28R > T25

thats the turbo i'm running... dual ball bearings all the way

Acually the GT28R uses a T25 housing as well, but a .64 a/r turbine. The T25 uses a .48 a/r turbine if un-modified so the T25 would acually have a faster spool because of the smaller turbine.. however a T25 CAN also use a .64 or .82 a/r turbine if upgraded. But then agian the GT28R is ball bearing so might have a same or faster spool than a wet bearing T25. I guess it really depends on what internals are inside the turbo itself.

also... i dont recommend the use of ball bearing turbos for street use because of how picky they are... the slightly amount of anything can really ruin them!

Hmmm... I hadn't heard that before. When you say that the slightest amount of anything can ruin them, do you mean contamination? In the intake airstream, in the oil, or in the coolant? Or something else, like overspooling?
We can make you a manifold also. We allready have a ecotec t3 manifold, wouldnt take much to make one with the t25 flange.
I can't find it on your website; how much? How much to ship to Canada?
