turbo build

[gnx7]

You are making headway. I could have flanges laser cut if needed. Don't worry about me.

You should install colder than stock spark plugs and close the gap a little. You should also have the injectors cleaned and verify that their distribution is equal. It is only about $10/injector. If you need a place to do it... let me know. If not you could be playing with a ticking time bomb if one is leaning out due to clogging.

To not upgrade the fuel pump and adding probably 100hp isn't the wisest move for only $100 investment when it could melt your engine. n/a is no big deal but forced induction is a science and to not do the basics you could rack up big tab resulting from an uber budget build.

You should for sure put an EGT probe just before the inlet to the turbine inlet in the exhaust manifold and get a boost/vac guage for sure. An air/fuel guage that reads off the stock 02 sensors is not of much use. EGT's are important for tuning under boost.

You may want to also look into alcohol injection as an octane buffer/charged air cooler in addition to your intercooler.

I'm enjoying watching the progression.

Here is some of my madness I built with Buick GN (3.8i 231ci turbo) powered RX-7's. Mid 11's with a stock GN turbo and off the shelf chip:

I recommend the MR2 Turbo plug, 90919-01180. It is one range colder, is platinum and already comes in the proper gap.

I totally forgot about the colder plug. Thanks for the reminder. I'm not thinking of this build as giving me 100 more hp, I'm thinking of getting all 212hp at 3,000rpm when I'm cruising down the highway versus having to wind it well above 4,000rpm without the turbo. I already bought a cheap a/f ratio gauge and a boost gauge and I'm watching for a cheap egt on e-bay right now. For right now, I'm just not looking for big gains, so that injector stuff doesn't apply. If this works, bigger and better mods will follow.

Dan, I'll be giving you a call about the spark plugs. Thanks for the great deal on all of the wonderful stainless gaskets.

No sense getting a new fuel pump if she's only going to burn to the ground anyway.

Hell, that's the spirit that won the west. Cool thread, keep us posted.

 

[Dusty]

just baught a new autometer egt just for you gnx7. Dan do ya got a price for the supra pump?

ha, the man is coming around.

I'm really excited to see the outcome of the build. Just imagine if you had ported/polished to a 4.7L

 

[elmariachi]

I have a stupid question/observation, having very little experience with custom exhausts, and that being mostly on boats. It seems to me that the exhaust path on cylinders #2 and #5 is a dead-end T rather than a swept away curve. Are you not concerned that could somehow negatively affect exhaust flow and temps on the manifolds?

 

[gnx7]

"log" manifolds aren't the ultimate flowing setup... but unless he plans to make as much HP/TQ as possible it won't hurt performance too much. With 4.5 liters of air pushing that turbo it should spool up nicely.

 

[semlin]

well he could spend a billion dollars for this one, but i am more in tune with his budget 50hp boost approach

Good Job DUSTY!!!

Hey you toyota guys. I am Dusty's brother and a jeep fanatic. I have not spoken to Dusty since last month but somehow I knew I could find him here. Dusty, sign up for AAA premier package now because it will tow you up to 100 miles three times a year. Do it soon because the long distance towing takes a while to go into effect and you should have it before you drive that thing. The farthest I go wheeling is Paragon which is 106 miles from home. If I need to, I will get someone to tow me 6 miles down the freeway and then call AAA. I know you are not going wheeling with that thing (yet) but having 3 up to 100 mile tows for $150 is well worth it considering the risk you are taking. Adding a seventh injector with some alcohol or windshield washer fluid (dune buggy style) seems like cheap insurance until you get the details figured out. Anyone else think this guy is obsessive compulsive? Good luck Bro, if you don't get AAA in time, call me and I will give you my membership #.

YES $$$$ and bring those Australian 1FZ manifold or JDM tarantula to the states

 

[RAYJON]

any more pictures of the second one???? stainless is cool...

 

[Dusty]

Just watch little Bro...she will run I tell ya!!!! And then mom will love me best!!! The details are worked out danget. And dont be poluting this fine forum with pics of your Heep-you need all that tow insurance for a reason.

today I fabbed part of the brackets to hold the intercooler-painfull. try to post pics tomorow.

 

[zoomzoom]

IM his other brother and a zuki man. (for now thats all i can afford in collage) good luck man, i hope everything works, not a bad job on the header though. i dont know what you two are talkin about, mom loves me the most, im the baby in the family. make sure you get everything worked out, i dont want to have to pick you up in the zuki.

 

[bandy rooster]

sweet build keep posting up your process its sweet.

how many more bro's with swweeeet rigs can we be expecting? lol j/k

 

[landtank]

When can we expect your mom to drop by and post about not drinking and having safe sex with a pic of her Nash!

Here is Dusty's past

Dusty, could not pass up the opportunity to show everyone your high school ride. Guess you probly have not told everyone here about the last idea you had on how to run a turbo and keep it cool. This time do it by the book. And by the way, get this done right so we can work on how to get some lift and bigger tires on that thing. If not, you will be riding with one of us.

Family affair

Now you boys quit arguing or I'm gonna get a switch!

Dusty; you have a front half and back half of your exhaust manifold. Are you going to weld both to a single flange or will each be welded to a smaller flange and then bolt each to the turbo mount flange?

PS: Ive had many jeeps and broncos. Maybe I should consider an FJ-40 with a turboed small block Ford???

 

[Dusty]

Thats all the brothers. Our family is kinda like the Duke boys with Lance driving the Zuki and Daisy in her cute little TJ. Dad will probably post a pic of his jeep sooner or later.

Got the intercooler bracket fabbed. was not easy but now is very sturdy. It was dificult fitting the intercooler in between the oil cooler and aux trany filter. Especially as I needed to keep room for the intercooler ducting. I was going to fab up all new radiator supports to bolt to but decided to just make an additional bracket. it turned out nice but needs some clean up. I had to keep intercooler on the drivers side to leave room for ducting elbows on the pass side. Note that I left the OE trany cooler in place behind the intercooler which is not ideal for the trany cooler. I could have put the trany cooler on the pass side but I wanted to leave the pass side of the radiator open in case I add an aux fan to that side.

I plan on welding the turbo flange directly to the 2 elbows (but wont weld the 2 engine flanges together-leaving them aprt to allow for thermal expansion)
