I am starting my own turbo project and was wondering what you guys thought about the best wategate for my turbo. It needs to be externally wastegated and i could either go with a delta gate or just a regular external. What are my options? Also waht about a boost controler? How would that fit in?

Thanks,
Justin

Tial wastegates are real nice.
For boost controller, I recommend Greddy Profec B

I havent had any problems with my Delta gate, so I can say they are fine as well.

Now what spring or bar do you put in the wastegate if it is gonna be controlled by the boost controller?

I have a 4psi spring and runn 8psi with my profec e01
Hav fun making your own kit. It is ALOT of work. I think i invested over 200 hours in mine.

Not to kill your optimistic goals but a person asking these basic types of questions is going to have one hell of a time fabbing, welding, bolting, wiring, his custom kit. You should probably read up on the current kits available and what they include and this would give you the basic idea of what you will need.

Kudos to you and your kit fab'ing.

I'm putting one together, but I'm having all the piping done by an exhaust performance shop for about $350. Definitely worth the money.

Beats welding and bending it all myself.

Cool, thanks for giving me an idea about the custom piping. Did you have them do 3"?

DA-MAX

iTrader: (10)

you're doing 3" IC piping?? seems like overkill. plus its VERY hard to find shops that do decent 3" mandrel bends in our area(MD/DC/VA)...been there, done that

96BLUMAX

iTrader: (3)

Not the IC, 3" exaust manifold and downpipe is what i wanted.

BoostedED9

does anyone make/sell the exhaust flanges to make custom turbo manifolds?? or do people just rig something up off of the stock manifolds???

check the pics in this thread, thats the basic VQ Maxima turbo setup-->

http://forums.maxima.org/showthread.php?threadid=231528

and I'm sure if you have access to a serious machine shop and some VQ manifold gaskets lying around you could throw together a real nice turbular manifold.

BoostedED9

thanks.... i dont really like the whole design of runing the y pipe all that way back around and up. if i decide to go with the turbo in the maxima my friend has some ideas already for it so who knows how it owuld turn ot, just know that it would be good...

a little OT but how much can a stock clutch handle??? thats the only thing im really worried about if i go turbo and im sure its not the easiest thing to change on a fwd v6.

We could make one at our shop. We're actually working on some flanges right now to make a tubular manifold in our spare time. But the question is, will it be worth it to make a custom turbo manifold? We're just doing it as an exercise in fabrication, and because we thought it would be cool. The manifolds are so short that a custom tubular one wouldn't flow all that much better than the reverse Y setup a lot of people are running off of their stock manifolds. Maybe port out the stock manifold would be a better option.

BoostedED9

does anyone have any pictures of the manifolds on the motor, i want to see how far down they actually go... i work at a shop as well and my friend always bugs me to let him make a turbo kit for the maxima since we do alot of custom jobs, so im giving in probably...hehe... just need to know more about hte motors capabilities and its stock drivetrain capabilities...

on_alert

typing a long *** response then having it get deleted cause the website ****s up sucks.

cliff notes: building a kit is really not worth it. If you are worried about changing a clutch, a turbo kit is 1000 X as hard.

im a cynical bastard today

BoostedED9

making hte turbo kit to me is easier than changing a clutch on a fwd v6, seeing as i ahve installed many turbo kits on cars. why do you say building a kit is not worth it?? i work at a shop thats what we do.....


i just want to know what the threshold of the stock clutch is and at what point of power it should be changed at.

Shadow

iTrader: (15)

The clutch on a Maxima isn't that hard. A turbo kit is.

A FWD V6 turbo is a whole different thing than a Honda turbo. We just custom built a turbo kit for my girlfriend's Integra. Very easy, the Maxima turbo is much, much more difficult. There is no room to work.

If you're even considering a turbo, change out the stock clutch. It won't really even hold at low boost. And seriously, if you're worried about changing out the stock clutch, don't consider a turbo kit. If you work at a shop, then the clutch should be easy.

i dont only build honda turbo kits man, we build them for every car so i know how it is to work with little spaces. one real reason im so worried about hte clutch is that i wanted to see if i could ride around on the stock one till i get my other clutch. if i have to change it then ill do it i just hate doing fwd cars they are pain a on the ***.

external wastegates - why do we have to use them instead of remote wastegates on our cars?
BTW, what turbo did you guys go with? i was looking at a 60-1 and the compressor maps look good with the numbers Ive run. feedback is appreciated...
one last thing - where are all of you guys with turbo shops? anyone in/near Florida?

DA-MAX

iTrader: (10)

external and remote are basically the same concept...a remote wastegate is usually has the discharge outlet plumbed directly on the down pipe than uses a pipe from the manifold(where the ex. wastegate would usually go) and that pipe connects to the wastegate "inlet". its more for situations where space is limited or "hidden" setups. I'll try and find some pics

Shadow

iTrader: (15)

You could go w/ an internal wastegate, but an external provides better and more stable boost control.

And the shop I work with is in Atlanta, GA. Where in FL are you?

tampa, not a far drive at all for me - your shop wanna do an install on a 2k2?
dont want internal/integral...

I don't think wastegate capability is a problem with any boost a stock engine can handle

Shadow

iTrader: (15)

This is very true. I guess I'm just used to seeing high boost DSM's, Supras and SR20DET's. Those guys run 20 lbs + all day. But on a low boost motor, it's really not a performance issue. I personally prefer external, but that's just me.

shop i work for is located in orlando..

Not sure I am reading this right, but it sounds like you are saying the lower the boost you run the less the importance of a good flowing wastegate?

I will save my comments until I know exactly what you meant by your post.

DA-MAX

iTrader: (10)

yes, thats what hes saying. not so much a "good" flowing wastegate, but the need for an external on low boost situations isn't necessary. internal wastegates don't really show signs of leakage until boosting in the teens ...I will using stock Mitsubishi TD04 and and stock internal watstegate on my Integra, most Eclipses run these up to 15psi before any signs of major leaks or spiking.

TellschMax02

iTrader: (2)

I would be more worried about running low boost (dealing with boost creep sucks) than I would with a leaky wastegate. The lower the boost you run the better flowing turbine/wg passage/wastegate you will need to get solid boost control.

As far as internal gates starting to leak - all depends what spring you have in there. You can get an internal gate with a 17psi spring and hold 25psi with out the flapper door being blown open. Also the stock 1G DSM 14B turbo actuator has an 11psi spring - I have ran a 16G (same actuator) up to 22 psi with no noticeable leakage.

I would never do a turbo setup again using an internal gate.

imo delta gates are garbage.. if you want to go with turbonetics then at least get the racegate. hks wastegates are real good too, but very pricey.. i recomend the tial 35/45mm hybrid

TellschMax02

iTrader: (2)

Not sure if you know this or not, but the Tial 35mm is discontinued. Although some shops may still have some stock, they have been replaced by the Tial 38mm. If you were getting a new one I would get nothing less than the 38mm.

Tial/HKS is the only way to go.

mingo

iTrader: (4)

sorry i made a type it's 35/40mm hybrid.. i thought the hybrid was a new model?

TellschMax02

iTrader: (2)

No, it has been around for a while. The only difference from the hybrid and the regular 35mm is the hybrid lets you run higher psi springs (actually dual springs). If I am not mistaken, the 38s can also use the same tops as the 40s. I would think the high spring weights would not be needed for boosted Maximas.

good lookin' out.. that info is real helpful thanx =D
