Re:Twin Turbo D16Z6 PICS

Thats crazy!!! And you're juicing!? Man you got some balls! You have internals? Hope so. Nice though.

Re:Twin Turbo D16Z6 PICS

that manifold looks very homemade, if you clean it up a bit it would look pretty dope, maybe high temp paint it. other then that it all looks pretty bad ass.

Re:Twin Turbo D16Z6 PICS

Your an animal! How much longer until a test run?

Re:Twin Turbo D16Z6 PICS

is that engine built?
I really want to know whether or not you get quicker spool than, say a TD04H!

What are the actuators set at?
When will you drop it in the car?

Re:Twin Turbo D16Z6 PICS

Damn that's cool, but a little too complicated for me. I think I will just start out with one turbo on my Z6. Let us all know how it goes.

Re:Twin Turbo D16Z6 PICS

looks interesting but i think you will have turbo bearing problems how is oil going to get to the compresser side of the bottum turbo with it sitting at such an angle the same goes for the exhaust side of the top turbo. any good luck

Re:Twin Turbo D16Z6 PICS

u went buck wild on those welds. hint. they make mandrel benders

Re:Twin Turbo D16Z6 PICS

The manifold looks home made becuase it is. I still have to finish welding than I'm getting it powdercoated. Hopefully it'll look good when its done. I don't think there will be any oil problems with oil becuase I'm running two oil feeds and two oil returns, I'm only going to tee the coolant. And I didn't have the $3000 for a mandrel pipe bender so I had to cut and weld bends. Besides welds makes metal harder, stronger and less ductile

Re:Twin Turbo D16Z6 PICS

all i can say is WOW :o, hope u give us some dyno numbers....good luck

Re:Twin Turbo D16Z6 PICS

"I don't think there will be any oil problems with oil becuase I'm running two oil feeds and two oil returns, I'm only going to tee the coolant. "

ya but the way the turbos sit cocked side ways all the oil will go to one side and not the other.

Re:Twin Turbo D16Z6 PICS

If the entire oil system is pressurized than wouldn't the whole housing be filled with oil? In order for the oil to only lubricate one side your saying that the turbo housing only fills half way? There is no air in the oil system. On that logic every time you corner hard the oil shifts to one side of the turbo. If it actually is a problem than I'll reduce the size of the oil return line of that turbo which would increase the oil pressure and fill the housing.

Re:Twin Turbo D16Z6 PICS

if you increase the pressure it might push past the seals when the oil gets really hot

Re:Twin Turbo D16Z6 PICS

That should prove the point that the whole housing is filled with oil. In order for it to push pass the seals that whole turbo has to be filled with pressurized oil

Re:Twin Turbo D16Z6 PICS

Your not suppose to tilt a turbo more than 15* I think. its for oil drain issues also.. You might be fine.. Then again im might smoke like mad..

Re:Twin Turbo D16Z6 PICS

the angle dosent look too bad, i think the angle is mostly for oil drain issues, if a turbo is on its side i dont think the weight of the oil will push it past the seals.

what car is this going in? very sick looking setup man!

Re:Twin Turbo D16Z6 PICS

and the rad is going to be where? :) jk, originality 100%!

Re:Twin Turbo D16Z6 PICS

Alright I just got off the phone with majestic turbo and Turbonetics and they said that the 34 degree angle of the turbo will not affect the oil getting to the compressor bearings. Putting the turbo at an angle was also the only way to fit everything in there.

Re:Twin Turbo D16Z6 PICS

you know that engine looks really really clean, cept for that manifold, until u fix it.

Re:Twin Turbo D16Z6 PICS

I could care less how a manifold looks...

infact, I think it looks good. Awesome idea though... very very awesome job. I wouldn't have had the patience to do something like that. Let us know how it does.

Re:Twin Turbo D16Z6 PICS

I've always heard 15 degrees max on tilt.. I could of swore I read that in maxium boost, maybe not..

Looks very odd, good luck!

Re:Twin Turbo D16Z6 PICS

what was the purpose of this project: 2 turbos spool better than 1 large turbo, twin turbos are cool, or trying to boost the hell out of it.

Re:Twin Turbo D16Z6 PICS

<= drools

Wow. You shoulda used an eg. They got a gang more room than these ef's. But none the less wow, ---- I gotta wipe my drool.

Re:Twin Turbo D16Z6 PICS

Well theres nothing I can do about the angles of the turbo now since the manifold is already built so all I can do is wait and see. The way they are mounted is the ONLY way to get 2 turbos to fit in a 90' hatch with the full rad. The fit is so tight I had to order motor mount inserts to make sure it doesn't hit against anything. And I know the manifold looks like hell right now, wait till everything is polished and powdercoated than criticize. The reason I did a twin turbo was becuase it was the cheapest way to go. I have about $200 invested...both turbos, 36x6x2.5 intercooler, water injection and all piping. I want to hopefully do an 11 sec pass for under $4,000...Including the price of the car and I have a good chance of doing it.

Re:Twin Turbo D16Z6 PICS

looks good :obut get readdy couse those motor mount inserts are going to rattle your fillings.I pulled mine out of my ej1 couse everything was coming apart with the vibebration.Hope its a race only set up.

Re:Twin Turbo D16Z6 PICS

Good Luck! let us know when it is all done.

Twin turbos are cool, LOL..

If I was going to build out a low-budget drag car, I would go with the biggest T3 I could find.

11's for 4000 is possible, but its scraping like a mother fucker. Jan (boosted9) had a z6 crx running 18psi on a stock z6 and ran a 11.9. You never said if the motor was built or not? stock rods? yes/no? I'd be a bit cautious on using direct port Nos w/ a twin turbo setup on a stock z6 ;) (let me guess, the NOS is for backup, just incase they dont spool?)

Re:Twin Turbo D16Z6 PICS

ive heard of diesels using 2 turbos in a series so that the intake portion of the first turbo would power the exhaust side of the next turbo. so u can build some outragous boost but i think thats on huge diesel motors. i think u might pop a honda motor

Re:Twin Turbo D16Z6 PICS

thats sweet man, i bet you could hit some high 11's and lower if you fill the waterjacket and build it, the best way to gain power and make sure it won't grenade will be to get friends with a shop owner and get free or cheap dyno runs. if i owned a shop i would let you tune on my dyno for free with that setup.

Re:Twin Turbo D16Z6 PICS

I can't say for sure, but I sure hope that d16 pushes those things up to speed. If I were you I would use heat wrap and wrap the manifold up to push more heat into the turbo to help out some... I'm not making accurate guesses, but I think you might hit full boost by about 4700-5200+rpm.

I was just dreaming agian... h22a1 in a rex with twin turbo... I'm going to need more money one day, lol. :-\

Re:Twin Turbo D16Z6 PICS

Damn! Only on HMT! How bout using a small turbo to help spool out a semi turbo. Snapping necks and axles.

Re:Twin Turbo D16Z6 PICS

The motor isn't built yet...when I first started this project I just wanted to give my daily driven beater car some balls and I guess I just got a little out of control. I'm going to see how this set-up works and if its good than its getting sleeved. I originally wasn't going to build it becuase I thought it wasn't worth building a single cam but now it seems to be a good investment. Hell, anything will go fast with 22psi and a 100 shot. (thats hoping for 11psi out of each turbo) What will one RHB5 max out at?

Re:Twin Turbo D16Z6 PICS

I didnt mean a turbo to power a diesel turbo
But this is what i meant:
some of garrett's diesel customers are demanding so much boost it takes two turbos to get there. every automotive twin-turbo system even sequential twin-turbo systems, run the two turbos in parallel, ridiculous boost is possible. it's a commo mistake to think of a turbo's work in terms of boost, but the turbo dlesn't care houw much boost comes out of it., just houw much more the air is compressed than it was when it came in . if that air happens to start out at 15 psi, as it might on a cold thick night in death valley, a burbo compressing arir 2:1 will discharge air at 30psi of absolute pressure. since boost is defined as the pressure about ambient, you have to subtract atmostpheric pressure to get boost. thirty minus 15 is 15 psi of boost. but add a second compressor and things get interesting. with bothcompressors doing the same amount of compressing, you might instinctively expect twice the boost. but instead of 30 psi of boost, you end up with 45.
how's that? remember, air going into the second compressor is already at 30 psi(absolute), and compressing that 2:1 brings it to 60 psi subtract the 15 psi of ambient pressure, and you have 45 psi . start turning up the boost and you can quickly see that two turbos in series can make pressure no single turbo ever could. that 45 psi would be a pressure ratio of 4:1, an ambitious feat for any single tubro. run two compressors at 3:1 in series and you have a pressure ratio 9:1, or 120psi of boost on a thick, 15 psi day. no single turbo can do that. with diesel engine makers asking for boost levels that would require two turbos in series(i dont know of anyone asking for 120 psi, by the way), garret started working on a single turbo with two compressors. the result is the low speed turbo, a turbo with an unfortunately dull name derived from it ability to deliever substantial boost at much lower speeds than a single compressor turbo could. that means longer service life, which is as sexy as it gets in diesel truck world. from the out side, the dual compressor low speed turbo look fairly conventional, with just an extra thick compressor housing looing a litle out of the ordinary. inside things are complicated. ina normal compressor, air gets flung axially off the tips of the compressor wheel, collected in the snail shaped scroll, and discharged intoa pipe. the discharge from the first of the low speed turbo's compressors, however, just wraps arond toward the turbo's center section , and does a backflip into the second compressor whell, sitting back to back with the first. the second wheel is physically smaller than the first. this is possible because the air tyhe air it breathes is already compressed, so agiven mass of air is smaller when it enters the second compressor than it was when it entered the first. its a good thing, too, since the discharge of the second compressor has to go into a snail shaped scroll thats small enough to fit inside the mushroom shaped passage carrying the back flipping air from the first turbo. at this poin the elegance ends, with no other way to excape the second compressor's scroll has no choice but to punch through the backflipping mushroom passage, giving the hightly compressed air a way to get to the neares intercooler. fascinating, but what use is a turbo that cian make 60 psi of boost at only 70,000 rpm of shaft speed? on a gas powered street car, its no use at all. on a high boost drag car running c16 fuel...maybe. this may remain a diesel only innovation.

Ok read it a few times and it will make sense
this is pulled from a writer in SCC and i spen all this time typing it.
i hope someone learns something from all my hard work

Re:Twin Turbo D16Z6 PICS

The only thing you need is to replace the backside windows with air ducks then place radiators behind them. With a heat shield welded in place just behind front seats will keep the heat out and the engine cool while opening the engine compartment for more room(bigger turbos). Do that and you'll win any bet.[img][/img]

Re:Twin Turbo D16Z6 PICS

Only an idiot would mount the radiator in their window...Than again only an idiot would bet his ZX6 that I couldn't build a twin turbo kit in 2 weeks.

Re:Twin Turbo D16Z6 PICS

that ---- is SICK :o, best of luck to ya, hope to see some more pics when your done, hopefully some videos ;D
