After 2 YEARS of building, it starts on its first try. Turbo FB
 
It started on the first try.

I did run into some trouble earlier. the trailing coils are now running backwards, T1 to T2 and vise versa. I dont know why, but this is the only way it works, I went through the haltech wiring to the coils, and all was good. It seams wrong, but its right when I check it with a timing light.

also had a small fuel leak on the primary rail.


Runs rock solid at 800 rpms and will idle as low as 600.

during its first warm ups, I ran it at about 1000.

It was making 45 psi of oil pressure, close to 18 in/hg, and held a steady 180 deg.

the oil temp maybe moved above the 140 mark, but Im not sure.

overall it is running fantastic.

It ran a little funny at first, and backfired pretty hard, but I realized I left the timing lock on. Once off, it ran smooth, with no hesitation on throttle dip-in and had a smooth return to idle, even with no BAC or dashpots on the throttle.


also, it does not hold fuel pressure at Key off. I pinched the return line and it still does it. I have an Aeromotive A700 fuel pump. it does hold a stead 42 psi at idle.


Right now its got a belt squeele that I need to take care of, which I think is the alternator not being fully hooked up.

I cant rev it at all or it will backfire hard, as it has a just a pipe coming off the turbo about 3 feet long. Just so I could get it started.

Once I get a full exhaust, and a o2 sensor in there. I can start tuning it an getting it ready to drive. that and the driveshaft.

Ill have some new pics and a short video of it running tomorrow, right now the battery is dead in my digi. and Im going to bed.

Sounds sweet man! Congrats!!!!:)

Max7 08-24-04 02:44 AM

There is light at the end of the tunnel, just a bit more, that first drive will be oh so nice :D

Awesome work man!!

Ported7 08-24-04 01:34 PM

Turbo
 
looks good!I dont know alot about turbos but that thing looks huge!I'll bet it'll make some power when you're all done.

fatboy7 08-24-04 03:01 PM

looking good. Your about to get to the fun part... boost ;)

82streetracer 08-25-04 12:12 AM

thanks,

yeh, I cant wait to feel the boost.

RUBY7 08-25-04 12:40 AM

That looks like great work well done, Think you definately have an ignition issue though, you say your trailing spark is leading yeah?

82streetracer 08-25-04 12:44 AM

no, the leading is working perfectly

the trailing is running backwards.

as in trailing coil 1 is firing trailing plug 2 and vise versa

Directfreak 08-25-04 12:54 AM

Congrats DUDE!!!!

gonzz 08-25-04 01:08 AM

Real Nice!!

FB II 08-25-04 01:46 AM

sounds like a beast. :D get that exhaust on! take it out and tuuuuuuuune WOOHOOO!

r0taryr0ck3t 08-25-04 03:01 AM

that is one of the most clean set ups i have seen in a while, i WISH my engine bay looked that clean, maybe it will look a bit better with the rats nest gone,e-fan and cold air intake?? lol but your engine bay pic is definatly sumthing to work towards, very good job....envious

nimrodTT 08-25-04 04:04 PM

AN connectors for everything! That must have cost a fortune.

About that backfiring; have you tried disconnecting the trailing all-together and see if it stops?

fatboy7 08-25-04 04:37 PM

About the trailing issue that you have, I had the same issue. Its fine as long as you correct it by switching the wires around, so that the front rotor triggers a timing light somewhere near the timing marks.

Blitz0309 08-25-04 04:43 PM

Congrats man, that rocks. You are where i wish i was. My car is just a shell with a cage in it. It might get work done if i ever get it brought back home.

Rx7carl 08-25-04 07:32 PM

Finally! Congrats. :bigthumb: I know how long and hard you been at this. Must be very satisfying.

82streetracer 08-25-04 09:17 PM

Extremely satisfying,

I had a lot of problems with my engine supplyer, some guy on the forum.

so the quality seamsed iffy. But it was super clean, inside and out. and made sucking and blowing sounds like it was sealing very well.

It was a huge relief when it started, and on the very first try, but I think I made my own luck on this one.


but man was there a lot of smoke from the MMO.

I am confident that the backfire was from leaving the timing lock on. It was sputtering hard on throttle tip in, and missed quite a bit. then backfired.

I turned it off, and instantly the car idle went from about 1000 ot arount 1150. and it reved freely with no hesitation or sputtering at all. I did not go higher than about 2700 or so. just kind of held it at different rpms, and listened for any kind of problem.

I had two guys watching it for fuel leaks and one had a fire ext.

hotty 08-25-04 10:02 PM

looks great.. can I ask you what the full setup cost you? and what you all have done :).. if you dont mind.. I would love to know stats as well on how much power you think you will be making.

oh yeh, the total cost to duplicate this, would probably be right under $1500.

This includes my original $1065 purchase of the car.
