I come from a very small market volvo community..

99% of the stuff I had to do is completely custom and my tuning options were subpar..

trust me when I say Im not tellign any body off but I was raised on the fact that

each CC in an injector can be usuable horsepower ..

So for 400 whp I would go with a 450-500cc to be safe and 1000cc just seems a bit overkill...

Lets skip the ebay turbo ********, any reccomended turbos for 6 psi and about 400whp? I want it to last me a while so nothing to crazy

Also will I need to run 2 blow off valves by each throttle body? and where is a vacumm source I can pull from

sorry for the noob questions I come from a stock turboed 5 cylinder inline 1 throttle body easy to work on motor 57 trim nos and all the goodies were hiding inside

yes you will either need a bov on each charge pipe going to the throttle body or making or getting a manifold made similar to the stillen SC manifold for the HR. as for a turbo a gt35r would get you what u want but doesnt have a whole lot of room to grow. your going to want some fuel rails a wahlbro 255 at a minimum but if it was me i would do the aeromotive 345 or the new 4xx wahlbro. and some 600cc injectors atleast (id do 850's if i were you though but you seem set against that).

Thank you ,

I have no intention of building this motor as Im still paying the car off,

I got it for 15 grand financed @ 2.5% interest rate...not the best deal in the world but a fair one!

Do we have any intake manifold options? Ive heard someone say the 300zx manifold is better

stillen has one but i dont know if u can buy it on its own. gtm was working on a kit that fit the gtr manifold on our cars but i dont know what happened with that, i know theres a few cars around with them on. and the stock HR motor is good to 500 ish whp and high tq numbers. i havent actually heard of someone blowing an HR up yet. i ran mine stock block at 530/490 whp tq for 4k hard miles with no hiccups at all.

holy ****! thats great news then 400whp should be no problem at all

what do you think a 400whp HR would do in the 1/4 on a good driver?

low 12's high 11's maybe?

Get a holset hx40 turbo. They are cheap to buy and oem dodge commons turbo. They make decent power. I wan one before my new power goal , build, turbo. I still have a holset h1c at home that im not using. Pm me if you are interested in it.

Much better choice than eBay turbo IMO

BTW I made 415whp @9 psi on a DD. I was told its a little more on a DJ

xslangx

DD or DJ?

sorry im very new to the 350 scene, not to mention JDM in general

jvelos3

Why don't you just have 1 BOV on the hot side right before the intercooler.

DD- dyno dynamics
DJ - dyno jet
It's no jdm or 350z terminology just tuning terminology...

im over on 6speed its kinda slow over there tho : /

xslangx

Oh I knew that -____- a lot of people run holset... whats the HX40 in equivallent to a GT35..I dont want to overboost.. 6 psi nothing more

I would like to see how this turns out with piping and final cost

konrad

iTrader: (15)

why ? are you looking for a kit like this also?

not really true, on the third gen camaro forums i used to frequent when i ran camaros i saw dozens of them blow, right around a 40% failure rate in the first 10k miles. EVERY one of those failures was from shaft failure, some of the shafts exploded and others had improper clearances and just ate the shafts and housings up. those guys dont care because they can replace the entire longblock AND turbos for 1k, not true on our car. most of those turbos where the gt35 knock offs as well in a twin setup, some where bigger but nearly all regardless of size where running under 15 psi, no way they where being overloaded especially since they where external gates.

also on injectors i have 0 issues with my precision 1200's

Yea why not I'm always open to new ideas seems like it would be easyier then a normal turbo kit and less crowding doin the engine bay

Has nobody made a good write up on a rear mount??? -__-

In all honesty the piping will be the easy part..Im debating should I be using 3 inch or 2.5 to the TB? Im pretty sure TB is O.D. 3 inch right??

The only hard part is going to figure out a seperate sump system with return and feed lines oiling the turbo...

Should run me about 1000-2000$ when alls done and said
