A new question for the turbo guys
#1
Hey I've been given a pretty sweet offer on a custom turbo kit. Tial components, garret turbo t3/t4, intercooler of my choice around $800 - $1,000. Whole system installed and tuned with ECU for like $2,500. Anyways I haven't talked to them about the specifics yet, but I am trying to work something out. I was curious what people are doing for wastegates.
Since there are two wastegates running a single external wastegate isn't as efficient as I'd like. What do you guys think about internal wastegates, single external, double external. Tell me what you guys think. Thanks!

BTW, 2500 including fabrication of all the pipes needed, etc etc?
As for wastegates, Matthel wanted an external, for what reason i never got. My friends 3000gt VR4 .. he doesnt care either way, the only reason he could think of was so you could change the size.

that sounds really good but i doubt it would be that cheap.
which tial components are they gonna use? i think they only make Wastegates and blow off valves. as for wastegates, i like external ones
lets do some math
Intercooler 800-1000
Turbo lets say 400
Wastegate=175
ECU=400?
thats 1775 already, this isnt including custom downpipe, intake piping, labor, blow off valve, boost controller and gauges(that is if you plan to use boost controller and gauges) that leaves 725 for all those other components. I highly doubt a should would even fabricate all this stuff for labor of $725. Not to be spoil sport, i HIGHLY doubt it would happen...but if it does...koo, and thats a HELLA good deal if they do it.

Ok well skimax, MaxedBandit, and Irvine97 heard the deal. it did not include guages. Yes it was a Tial wastegate only. HKS SS blow off valve. Here's the break down
Garret T3/T4 = $400
I/C = $800
Tial Wastegate = $150-$200
Blow Off Valve = $300
Fabrication = $300
Install = $400
I don't know if they're going to piggy back, but the guy mentioned the JWT ECU. The shop only works on Nissans and I think is willing to give a deal since it's the first Maxima they'll work on. Regardless, they told me I could get everything I want for much cheaper than the Stillen SC would cost.
Ok so it sounds like external wastegates are what you prefer. The thing is, if you only run it on one bank, isn't there going to be additional turbo lag?

Re: Where
That statement is totally unfounded. Actually SCing is not has hard on an engine. But then again it depends on the amount of boost/timing/fuel maps/and how you drive the thing.

so that price doesnt include Boost controller or any gauges. THe price of an ECU wasnt added in either. Your forgetting 1 important thing also. Additional fuel. Youll need some sort of additional fuel setup.
$300 for the blow off valve is crazy expensive!! Everything else is priced pretty good but that blow off valve. You can buy Blow off valve kits for much cheaper then $300. A universal one shouldnt cost you more then $200.
Im assuming the $800 for intercooler includes endtanks and piping? Thats a really good price for fabrication and install. The shop might be in for a surprise!! There's more then meets the eyes. Once you get in there you find out you gotta do this gotta do that. I wouldnt recommend you run the turbo off 1 bank of cylinders. heehe
no specs or numbers yet BrianV. I MIGHT dyno it once after the motor is put in...All i can say is i was boosting about 6-8psi when i raced Lynn and we were very close. He puts down 269 at the wheels. He has a supercharged 97 Max

Well I was guessing on the price of the BOV. I wasn't sure. I don't know how they're doing ECU/Fuel. He said he doesn't like the idea of piggy back. I think an Apex SAFC might be in the work somewhere. It was a small chat, but $2,500 was definately a number he was happy about. I'm looking at the Apexi intercooler for around $800.
#13
Matthel and I calculated the cost of making a turbo for my car... which came out to be about $3200-ish. This didn't include the boost, EGT, air/fuel, and fuel pressure gauges.
If you can get all that done for $2500... then go for it because $3200-ish was only for the parts. Labor was going to be done by us.

Brian, if your questionable about the shop not knowing much about Maxima motors i would pass. Fuel is really important and they shouldntt need to know bout Maxima motors to know how to get additional fuel. Youll need more then an AFC for additional fuel. As for a fuel pump, you can use that Walbro fuel pump everyone raves about, sounds good.
Apexi has 2 universal intercoolers, GTR one and Silva one. I doubt you can fit the GTR one in so we'll consider the price of the Silva one. Silva core goes around $500-$700. Retail is $685 i think. Then youll have to get endtanks that range from $40-$80. Those endtanks need to be welded to the core. The intercooler will somehow have to be bolted into place, maybe drilling into your bumper support. Then depending on which way they are gonna route the piping, you may need elbows or U's. You get the point tho rite? all this work involved and this is only the Intercooler. I think its over budget already.
The shop that quoted you that price i think they dont know what their getting into, and once they start on it they will find out it costs more and more stuff need to be done. Btw, which shop was this? but hey, if they'll do everything for $2500 ****** that deal while you can! Id borrow a Max juss to have it done, then take it off and sell the turbo kit.

Brian, how much boost are you planning to run? if you go under 8psi, maybe juss cut out the intercooler, it makes the piping ALOT easier to do and itll cut costs down. Although id be scared in LA summer weather...

Turbo 3rd gen
I was cruisin on the stip sunday night when i saw this 3rd gen parked in a lot with his hood propped... me and yoitsok decided to walk over and see what he got... he had a 300Z single turbo in his 3rd gen... it looked sick... BOV was loud as hell passin by the lot... sad thing is i kept on his rear bumber the whole race... i bet if didnt fill up my gas tank 5 minutes before and if i was still running close to empty i woulda kept right next to him or even pass him... anyways... its so sad he did all that work to have me just chill the whole race long by his bumper and get his a$$ handed to him by a stock 5th gen

the 300ZX isnt a VQ motor, its a VG. I think some of the 3rd gen guys use those internals or parts. The VQ is an aluminum block and supposely with cast in iron liners so its better then a usual all aluminum block.
Brian, you can run more boost juss dont punch it in 1st or 2nd. Youll love the pull in 3rd or 4th or 5th...

i think the Tial wastegate is setup for a boost controller. Its not that much more, You can juss get the boost controller and not use it, so then you dont have to go in there again. Get the Tial .4bar wastegate. Thats almost 6 pounds boost then you can boost up via boost controller...sound good?
#25
I'm gonna check him out. I also know the owner of FastTrax turbo which has now combined with HKS. I also am close with a shop that just moved over from Japan. I have a few options, just gonna shop around first.
#26
All I will say is get a price in writing before he does the work, that way, he can't tack on "hidden costs". Also the only other reason I can see him charging so little is he wants to fabricate these as kits to sell and needs a guina pig. That is a great price....
#28
Talk to TurboMax95, or contact Jim Wolf Technology, www.jimwolftechnology.com They don't make turbo kits for the Max, no one does actually, but they might be able to point you in the right direction. Good luck.
#29
Outta curiosity, I was reading this thread, and turbo95max mentioned running the turbo off of only one bank. Doesn't that mean that one bank of the engine will have more back pressure than the other, and the two banks producing different amounts of power due to one bank being able to get rid of exhaust gasses quicker?
If you have a manifold on both banks, doesn't that mean that you'll need two turbos? Just wondering... trying to picture how this would all work. Thanks!

wow old thread brought back to life...anyways, no im running the turbo off both banks. No custom manifolds used, juss using a custom downpipe that brings exhaust gases from front and rear banks. I dont think the turbo manifold clears the firewall....not sure
#31
ok. ok. it's making sense now. I was picturing the turbo on the DSM car in front of my house (how the turbo sits on the manifold) and on my dad's 90 and brother's 94 z twin turbos where the turbo also sits on the manifolds.
excuse me if i'm being ignorant here, but then where's the down pipe? would that be a piece that replaces the y-pipe (bc that would be the first point where the two banks on the engine joine together?

yea the downpipe replaces the y-pipe. Y-pipe is anohter work for downpipe. anyways, yea we could have done a custom manifold setup but why do that if its not needed? have you seen the Z turbo setup? its CRAZY...so much work to get to those turbo's. hate working on Z's

Also the Miata kit also relies on changing the manifold. The Talon in front of my house also has the turbo attached to the manifold, so I was a bit confused.
Does putting the turbo in the downpipe cause more turbo lag? Just a curiosity question.
Thanks! Just trying to picture how everything is put together!

Ugh. This thread is going nowhwere!
1) Don't use a 4 cylinder turbo set-up to compare to a V6 turbo set-up. Not the same! And don't compare a TT V6 turbo set-up to a single V6 turbo set-up. Not the same.
2) Going twin turbo on a V6 is NOT easier. It's alot harder and alot more expensive!
