Turbo guys

[Yaj Yak]

i wish my turbo/downpipe weren't the 5 bolt flange from zzp but rather a vband clamp.

lining up everything sucks.

I dont have the cross over anymore... buddy of mine hacked it up for a dead project.

I still do have the downpipe, collecting dust.

Can see here what I am talking about. I dont think it "hurt" anything really as car did perform well enough.
But sharpish bend right out of the turbo.

O2 sensor was mounted right in that area which was dumb as it burned up o2 sensors. Really needed
to be a foot or two further down. Wide band at the end of downpipe never had issue.

That turbo placement is too far over on the drivers side though, it would have been easier to run your DP if you moved it back towards the engine. Obviously you had to do that for a reason though. This guy isn't shooting for big power so right off the X-over with a flange should be a perfect placement for a 2-1/2" downpipe to run past the brake booster and the ABS stuff. 2-1/2" piping is good for ~450whp.

[MENTION=653]BrianG[/MENTION] needs to go turbo

I hate you.

My big problem was I bought a "Z7" kit off clubgp.

Notice the quotes? ... basically it was a Z7 clone. Not very good either. Thick nice pipe,
but nothing lined up.

When the T67 turbo from ZZP showed up ( i bought that new from them ), it didn't fit. Turbo physically sat on the wiring harness for trans. Downpipe hit everything.

So we hacked both cross over and downpipe up to get everything to fit.

ABS was already gone and had the smaller booster. But next issue came to cross over. was marked "done" without checking downpipe fitment properly.. By then it was a "send it" moment and downpipe ended up way it was.

If we had angled the T4 flange better, it wouldn't have been horribly bad.

One thing with the turbo pushed out further like that maybe helped in some way of
keeping direct turbo heat off the motor and trans itself ... but need a passenger intake
to really do that.

Yeah, I kinda figured you had some kind of nightmare

Wait a minute.... Where are YOUR car updates?

Ill update my thread again once I know more

 

[Yaj Yak]

weird. thats way more gnarly than my setup

but i bought my x-over and z7 dp brand new from zzp

 

[Yaj Yak]

just lining up the bolts SUCKS

just lining up the bolts SUCKS

Yank the turbo/DP when you do the flexplate and have someone weld on a V-flange. You can kill 2 birds with one welder.

 

[10sec]

OR put a flex between the bend that goes down behind the motor and the flange, that'll help a lot too.

EDIT: Or both.

yeah, im definitely going to go with a v-band outlet turbo. Just not sure what size exactly yet. I wish i kept my turbonetics 62mm off my firebird when I put the 76mm on, but i sold it.

Bam.

Dump that single roller chain before you destroy your motor.

Is there a problem with them?

Hmmmm..... Very interesting

 

[TurboTPI]

I used one of these on my 4.0l jeep. It seemed to be sized pretty good for that engine, but they dont rev past 5k rpm. Not sure it will flow enough for a 3800 that revs over 6k rpm. But the internal gate would simplify things for sure.

[Yaj Yak]

for what yer shootin' for i dont know that revving over 6k will really be beneficial at all.

i think my car shifts just before that

You'll want to have all the exhaust crap bolted in after you tack it to help prevent warp from welding even with a V band. I had at least one V band flange that warped and doesn't seal because I didn't have the band tightened down, even with a 6" flex on a 3" pipe it was barely enough to offset the warp.

Mmmm. Brings back some memories...

I thought ZZP recommends the shift points for VS cams to be around 6200rpm? Maybe I'm wrong though.

 

[10sec]

The turbo I posted is better, that internal gate turbo is wayyyy too small.

Shifting at 6200rpm is just about right for that cam, and with the turbo it'll actually make power up there, unless you get that little pea shooter turbo you posted.

Seriously though, don't get that turbo.

 

[TurboTPI]

I was kinda thinking its on small side for sure. Ill stay away from it, and find something bigger. Thanks for the input

 

[GTPpower]

Is there a problem with them?

Yeah, they eat the tensioner because they have a much smaller contact point than the stock chain. The stock chain is way better.

I thought he meant it was OEM chain when he said that, OEM is always the best.
