Before i get bitched at, i have done as much research as possible.... i have been on this site and dsmtalk.com for the past 3 weeks.... ive learned alot more but im still missing links...
First of all i have a 420A that im looking to turbo to around 5psi. Im a cheap bastard but i have mechanical skills and a pretty nice machine shop.... i have a stock manifold from a blown engine in my basement.... my plan was to make an adapter plate from the manifold to the turbo so i could mount the turbo and not have to buy a custom manifold.... second i was going to make custom i/c pipping from jc whittney.... i also have a spare oil pan to tap the oil return line and a welder if i need it..... now my questions are,
1.) what car could i get a turbo that would suffice me 5psi, would the 1g turbo work
2.) what wastegate (if any), from what car would be 5psi, is there any cars that come with a turbo with an internal 5psi wastegate
3.) where do you recommend tapping the oil line to the turbo
4.) do i need a fmu?, if so what do you reccomend
5.) do i need to alter the MAP sensor?, Do i need a bigger fuel pump or will the FMU handle it.
Please let me know if i am missing anything and i dont need the remarks telling me to use the search button because i use it all the time.
If it helps at all my current mods are AEM CAI, AEM Tru-time cam gears, MSD DIS ignition, 60mm Jeep throttle body, Greddy exhaust, AFX underdrive pulley, Accel 8mm wires, Denso Iridium plugs.
Thanks in advance.

you will need an FMU and another fuel pump, the cartech will work and you can pick them up cheap but a Vortech S-FMU will be better. To alter the map sensor, use a Missing Link from group 5 motorports. a 1G turbo is fine to run at 5 psi and the 14 b turbo will grow some to if you decide to upgrade later on the internals and more boost. the wastegate on the 14b can be adjusted to open at 6 I know because thats how my buddy's integra is set up right now. on the oil pan tap, 3rd bolt from the right on the front side, go one inch down and one inch left and tap in there. I think that was all you asked. Good luck

thanks for the input.... i still have a couple questions... where do you tap the oil line that goes to the turbo, im guessing on the head but i was wondering where would be the safest place....also do you have to alter the 1g wastegate to open at 6psi.... any other little things that i should be concerned about
thanks again

i forgot to add one thing.... when you say i need another fuel pump, do you mean add another one in, or get a bigger one.... some info on this would be appreciated

Here's what to buy.

Get a manifold from Motofool. Dont even waste your time trying to fuck around with the stock manifold.

There is a 5 psi wastegate from a HRC kit on the for sale forum. Buy that. Stock 1G's range from 7-10 psi depending on the year. The HRC one should bolt up to the 1G considering they are both Mitsubishi TD05H series turbos.

You'll need a custom downpipe. You can rig one up like the HRC kits do but they suck. You'll want to spend the extra $100 and you can have a properly made one.

You'll need a fuel pump. Walbro 255lph are about $75 on DSMtrader. If you use DSM 450 cc injectors you'll be able to use a stock GST fuel pump. Just make sure to keep the boost down. I have a GST pump for sale $25 shipped. You can get the Cartech FMU's pretty cheap but they arent as good as the Vortech unit.

For the MAP sensor by-pass you should get a missing Link. They're about $60. I can get you the Black box for $40 shipped if you'd like.

id like to start off with the most basic turbo setup first.... i was wondering how accurate an air/fuel gauge is.... instead of buying a new fuel pump right off the bat, id rather get the turbo and engine running first and see where to go from there.... my plan was to just get the turbo, intercooler, blow off valve, oil line, and wastegate installed....then run the car at high rpms and keep an eye on the a/f guage, if i see that im not getting enough gas i know where to go from there..... also what does the missing link for the map sensor actually do....what does it do if you dont have one....i have heard from other people that you dont need a missing link.... one more thing if anyone can help me...where do you suggest tapping the oil line from the engine to the turbo..... thanks in advance

>id like to start off with the most basic turbo setup

Not very accurate at all unless your are at WOT. If you truly want accuracy get a wideband o2 sensor or a logger of some kind.

>go from there....

You will not get enough fuel.

>my plan was to just get the turbo,

You will not get enough fuel.

>also what does the missing link
>for the map sensor actually do....what does it do if you dont

>a missing link....

The missing link is a check valve that tricks the MAP sensor into not seeing boost. Without it you'll hit fuel cut and possibly damage your MAP sensor.

>one more thing if anyone can help

>to the turbo..... thanks in advance

Back of the block. Oil sending unit. Take it out and put a brass T in it...there's your oil line.

any other good helpful hints? about how much will the custom route cost. why is the stock manifold such a bitch, doesn't the 14b turbo bolt straight up to it. correct me if i'm wrong. more guidance is appreciated.

No, the stock manifold is for stock NA applications only. Your best bet is to get ahold of Motofool and get one of his manifolds. Thats what I would do.

I think someone did actually mount a 14b on the stock manifold. Wheatking maybe? Something about the manifold had to be modified - stud locations or something like that. Also, there is a downpipe fitment issue with doing it this way - you have to ditch the A/C compressor cause it's in the way.

Any wastegate can be modified to crack at a lower boost - http://www.denverspeed.com/wastegates.html

I think these guys are thinking of the stock manifold from a 4g63. And of course that won't work.

actually we were talking about the stock 420a manifold and yes it can be done....it was wheatking that did it...he has pictures posted on asog.net....the only thing about it is you have to lose your a/c.... while im replying does anybody know of a write up on how to alter the stock 14b wastegate to 5psi?...and where can i find a cheap accel inline pump, what partnumber or specifics please....thanks

umm, like I said ^^^
