    200 I6 finally going back togther

     



    finially starting to go back togther after several months ( car's been under the light since the fall, Nov I think ) and the current cost is just over $3,000 but soon to go up...again.

    anyway, friday I put in the rear main oil seal, and all the bearings, today I dropped the crank in, torqued it, and started the plastigauge prosess. so far I'v done 3 out of 7 mains. there all coming out at .002 which is ok, hopefully there all within spec. I'll have to pull out the old '74 Motors manual we have, to get the real spec. my teacher said between .001 and .002 was ok, but I seem to remember when I looked at the spec b4 that .003 was the max spec.

    Still have to get a fuel preassure regulator ( getting a Aeromotive 1 for $125 ), turbo piping and couplars, and a wastegate, BOV and a intercooler ( a company on Ebay has cheap 1's for $50 but they have 2 yr warranty's )

    why use a BOV? a bypass valve will actually bring your performance up a little more, sure it doesn't sound as cool.... but thats not that important... it will also prevent from back spinning your turbo which isn't that common of an issue but it still exists when using a BOV

    what does a bypass valve do? force air back into the turbo inlet?

    Matt sounds like a really cool project. Don't even think of the money your spending.

    Sounds like your well on the way. What turbo, int etc...are you using? Maybe you can hit the bone yard for parts? Would the T bird turbo coupe stuff work maybe? Have you looked at ATR for parts? They are expensive but very good. I spent lotsa cash with them in my old GN days.

    good luck bro!!

    yup a bypass instead of just blowing the pressure out into the engine bay, it forces it back into the turbo, which keeps it spinning the right direction and will reduce turbo lag by a small bit..... if the turbo backspins you have a chance of having the impellers disentegrate, eating through the turbo and causing a very massive oil leak at the same time

    I'm using a '78 Buick 231 turbo from a Regal sport, but running an external wastegate, and blocking off the old internal passage ( I don't have the swing valve or actuator ). I bought a lot of goodie parts that I relle didn't need. 1.65 Roller rockers from Yella Terra ( Australlian import ) is among those parts. also a billit dual roller timing chain, Comp cams sells a single roller that would have worked but, I decided to get the good JP performance ( Australlian Import ) timing set. I could have just run a off the shelf Isky cam, but I bought a custom 224/224 .495/.495 ( figured with 1.65 rockers ) from Clay Smith Cams, which has 4* of overlap and should render 300 HP @ 5,500 RPM. the pistions are Speed pro, but not for a 200 6, there actully Ford Tempo 2.3 4cyl High swirl flat tops, .030 over. The 2.3 shares the same bore as the 200 6, they are moderatly related. the cyl head is a later model D7 casting head, bigger ports and valves ( also bigger chambers ). compression will be 8.35:1. the distributor is also a later model, it's a DSII and I will fire it with a MSD 6 BTM which I have.

    That's right..... I forgot you were using the Garrett turbo. I think i have a aftermarket turbo inlet that's bigger than stock. If I can scrounge it up you can have it. I had a few of them and pretty sure it's in the tool shed.

    Everything sounds nice!! Good job and can't wait to hear how it runs!!

    I'll be getting a video cam here soon, initial startup and cam break in will be videotaped at school, as well as the tuning prosess, cause the 'out of the box' Holley 2300 isn't 'out of the box' when you have to pull it apart and modify it to take boost. I will upload the vid's to my website

    you're gonna run a carb now? i thought you were gonna go TBI? or is that just something you're going to do later and for now just running a carb?

    I was going to run TBI EFI using a modefied 3.8 CFI TBI and a Megasquirt II ( has ign controls ) but I found out that it wasn't the best idea. because under boost it would have gone lean if the engine was tuned 'right' because the map sensor can only see boost, it cannot see airflow, if it was spooled up at 2k, it's going to use the same values up until the engine blows from running lean. Megasquirt only uses O2 sensor readings below 70% throttle, otherwise it uses open loop fuel tables. it would have had to be tuned rich to get the right mixture's for high RPM boost. so until they come up with somthing that uses a MAF or uses O2 sensor readings above 70% throttle. so for now, I'll run the Holley 2300 2bbl modefied for boost, and use the MSD 6 BTM for the timing retard.
