Thumper

Phil when I was running 23 psi on my holset setup I was trapping 123mph. In a 2500lb car with me in it. At 19psi 119-120mph. So the cam really hurt it again. Don't you have hydraulic heads or did you convert them? If you have hydraulic you might be getting blead down from the higher lifter and faster ramp up.

LOL we think alike I would get a 325i 325is 325e 325es e30. The e's get better gas mileage and have more torque. The i's are more sporty. The s's mostly add a limited diff. Good luck

First one is better.

Intake leak also will cause this. Check torn boots and gaskets.

Damn cats and always landing on 4 legs. You need to break the legs first then throw the cat. I guess they aren't teaching the basics in cat-throwing classes anymore.

I use to work at a muffler shop and did atleast 2 converters a day. The converters are very strong when you are trying to push on them but when dropped or hit with a hammer they can and will break apart easily. Then again most of my experience was with aftermarket cats. The only OEM's I messed with were already broken apart. So maybe OEM's are better made than aftermarkets nah...J/K:icon54:

Congrats on the baby. Sorry don't have much info on the car theme. My nephew is all about trains.

Nah the concussion from the back fires were hitting the cats so hard that they broke up the pieces. If you drop a cat on the ground its a good chance it will break apart so they aren't really hard to break. Either way yay lets ruin $500 cats. (from dealer prob more)

LOL That was a good one.

On ls2's and ls1's I usually tune for 13:1 at full throttle. 14.6 is great for cruising but for full load it needs to be richer. Looks good though. You might also try adding some more timing after torque peak to help your top-end alittle. That is along as you don't have any Knock Retard. Nice numbers!

Wow thanks for the vid. I think it looks good. Now that we know it goes fast and handles great my only concern is how does it drive. Does it drive like a heavy great handling car or a light great handling car? Either way:mparty:

I'm going to see how far the junkyard turbo will handle before whatever blows on a $450 complete turbo engine. We will see:flamedevi I also see Jon's point. Doesn't matter what you are running you are still faster than you were so yeah good luck either way. Me I like to make goals and engineer a way to do something that most can't do. 11's with a t3 is one of them.

You should fit but you will have to worry about wearing a helmet.

After I megasquirted my red Z and was running the stock t3 still I was running against low 12 cars. I raced a 600cc motorcycle that ran a 11.1 earlier that night at the track with a drag slick. And he only beat me by 3 cars. But can't compare that to anything. My guess at its peak I was running 12.2 nothing faster so I think you've got the fastest. But I say whats another 11 second l28 with lots of stuff done to it compared to be the ONLY 11 second l28 with the stock turbo and longblock. So keep the t3 and tell us what it can do I will be running a t3 soon and will be seeing what it can do before it blows up so you might have alittle competition. That is after I have the new turbo ready to go in:)

I WAS SEVENTH!!! Must make note never do that. Atleast he got back up to 10th. I wonder what all those people he passed on the pace lap were thinking

I like the way the car looks now. How much trimming did you have to do? You might want to try some regular lights down there. Maybe some 4"ers Not sure on the size of the hole though.

I've bought 3 zx's bought only two different ones. Sold one and bought it back put more money into then sold it again:( My first one was the best it was lovely named by a member on here as the "GHETTO BEAST"

Everyday except wednesday of last week and tonight i've worked on the dang car for atleast 1-2 hrs. Last 2 weekends all day affairs (10+ hrs) can't I have a break.... I can get a zx for $150 from a jy. They will quantee it works nice when installed other than that hah. I guess i'll be doing it this weekend ontop of my rear poly bushings.

Yepo carbs are alot smoother on the dyno but I noticed that smoothing was set to 5 which is alot high for my taste. I prefer to have it lower say 3 so you can see the bumpiness. That way you can tell if you have too much timing before you can hear it.

K just wanted to make sure because my only Non-turbo tuning experience has been with my ls2 which is a high compression v8 vs a mid compression L6. Yepo major drawback of carbs always needs adjustment when weather changes. So you were running 32 degrees of timing on that run? I am running 35 right now on a 8.5:1 fairly stock motor with 13:1 afr's. I didn't notice in any improvements with my butt dyno with more timing and I don't think there would be. Even 35 i've heard is too much for optimal combustion. BTW nice tq curve. 3500-6000 nice and broad

Is it just me or does the afrs look alittle lean. I've always thought 13:1 was good for n/a engines and thus tuned my engine for it. Seat of the pants feels faster with 13:1 then 13.5:1 for me. So you might have some more power if you richen it up alittle more.

Ok here is the latest. It either just started to rattle at idle or my idle is higher because of a leak in brake booster so its rattling. Also it is slightly worse when its cold. Tranny fluid is topped off. It could be the countershaft bearing but not sure. I thought that was a problem though for only zx trannies not early 5spds?

That would be interesting to see the limit of the holset turbo on a l28. Just disconnect the wastegate line and let us know.:flamedevi:flamedevi What lasts longer engine or tranny?
