  • Rebuild/General question's

    So as some of you know the short block in the SVO is pretty torn up. For some reason I have really deep scratches in the cyl wall's. Mr Flemming brought to my attention that the ring's may have not been filed/gapped correctly.

    So I have some money saved up and I'm ready to rebuild the mtor or a new motor for the car.

    Any tip's or thing's that I should look for when talking to the machine shop.

    HP goal is a honest 250-270 to the wheel's.

    Should I try to reuse the .40 over RE piston's or say screw it and run with the stocker's if I can on a different block?

    After doing a little searching it seem's that a good stock bottom end should be able to handle my HP goal.

    Every one agree with this.

    I still need to replace the heater core and have heard people say to run a ford part. Any truth to this. I was just going to get one from NAPA/CarQuest.

    I need new koni's in rear. That's a no brainer.

    I also have spring's in it that where originally from a sn95 car. I like the ride height but they bottom out in the rear over hard bump's. I was thinking about the FMS B or C spring's. I did some searching and it seem's that most people with them like them. Anyone have a different suggestion.

    Here's my combo. If you guy's could look it over and recomend any change's that you would make to it. I'm open for any suggestion's and since you guy's are the SVO expert's I'm all ear's.

    85 9L
    LA3, 35's.
    255 pump
    Gillis
    3inch exhaust, 3inch cat, magnaflow
    Spearco front mount (custom) blow off valve
    T04E 50 trim
    RR
    stock head
    ported E6.

    I want to drive this car to the next reunion so I need her to be able to make the 1200 mile trip. I obviously have plenty of time to make sure that everything is correct.

    Please post up. I have pretty thick skin to I wont be offended if you guy's dont like my idea's or think I should change something.

    thanks guy's. Any and all info or critisism is appreciated.

    Get a new block ( junkyard motor will do) and just do a stock rebuild on it. ON TOP OF THAT. Have a head ported/big valves/cam to match that big honker turbo you have. You'll reach your goal with no problem.

    Get the B Springs for a more comfortable ride. C springs are pretty hard.

    Dont forget to check your clutch while you're in there and replace it if needed.

      If you are coming down from colorado -- stop and pick up chris roth on the way ---

      I'd have to agree with bud -- to hit that 270, you are going to need more air going through the head than stock. It's will be a restriction for that big turbo.

        Don't forget to port the intake and exhaust manifolds while you have them off.

        As for a block, you can use a non-turbo one if you figure out the turbo oil drain (no biggie though). If you go with a DIS block out of a Ranger or Mustang, the odds are good you can come across a lower mile one with some looking. Yea you'll have a small journal block, but you'll also get a small journal crank with it if you get the whole motor.

          Thanks guy's.

          Clutch..10-4 good buddy. I also found a RAD direct pull bellhousing that I'm going to use to get rid of theat darn dog bone cable.

          Head... Can do. Hopefully I can find some one local that I trust to touch it. What valve size's should I run with and which brand/vendor.

          Intake's... Ok I've done a bunch of searching and I cant seem to get a straight answer on this.
          Are the square intake's that much better. I have the tall intake's from a 86 T-bird that are similar to 86 SVO that I could port. Pretty sure that I will also need a different dipstick and my fuel line's looked like they would fit. Or should I just work on the iline intake's?

          Chirs Roth. LOL. He would have to meet me at my house. The last time I drove to his house my old canyon red 85 got rear ended.

          Cam.. Will a A237 fit the bill. I've heard of to many horor storie's with big cam's and the stock head. I would rather not open that can of worm's if I can help it.

          I just happen to ahve a DP/DIS block in my garage from a previous project. I'll have to tear it down and inspect the cyl wall's. I found a complete 2.3t from a anniversary car that I can get. They want a little more money than I wanted to spend but hey, whatever.

            I definatly agree with bud, the head is a big restriction..

            A friend has the "C" springs in his SVO, I don't recomend them for street use.. If you do alot of driving, personaly i think the "B's" are much better.. (should get mine "B's" just after the holidays)

            I don't like to over-bore blocks.. IMO, I'd use a new block..

            Just a thought........

              IMHO, head work is always beneficial but in this case, not necessary to reach your goal. Keep your stock valves! The extra cost in hardware/machining required to install is just going to be a PITA on a reasonable combo/goal. A cleanup/port job with stock valves and maybe new springs will do the trick.

              You have a great turbo that is well matched to the engine. A cam would compliment it very well, something a bit milder than an A237.. There are some mild sliders around for around $100 that you would love, no geometry muckups either.

              You're gonna be stretching the 35#ers to the upper reaches of their duty cycle. Think about some 42# ers and an EEC tuner. (You've got a .63 turbine housing on that To4 right?)

                  As for a cam, ensure you have minimal valve overlap, as it does not agree with a turbo engine.

                    yep it's a 63.

                    A friend can burn chip's using the Diablo and other hardware. He swear's that he can tear into the LA3's etc. So 42's shouldn be a problem along with a tune.

                      I installed 1.89" intake and 1.59" exhaust valves in my head. Anything larger than that and you start shrouding the intake valve.

                      From what I've gleaned from here and elsewhere, there isnt' alot of difference between the inline and square intakes in stock form. However it is much easier to port and modify the square intakes. You will need different fuel rails if you go with a square intake opposed to an inline as the injectors are spaced slightly differently. You will also need to drill and tap a extra hole in the head unless you're using a post 86 head.

                        Ok.

                        Port my square intake's and double check my fuel rail for fitment.

                        Use stock piston's and stock bore, which is what I wanted to do anyway. I could prob turn the RE piston's on the "other" 2.3t site to recoupe some money.

                        On the cam issue. I was under the impression that everyone want's to use the roller cam's and not the slider's. I just happen to have a 86 spec cam laying around somewhere that I could also use in place of the RR.

                        On the head issue. The head is actually from the same turbocoupe that the intake is from so that wont be a issue.
                        As far as port work and valve's are concerned I will have to see how much the bottom end is going to cost me.
                        If money become's tight would it be safe to say that light port work would be more benfcial than just the big valve's?

                          I'd say so. It's better if they are done together couse the head is already off, but if I had to chose-I'd go with port work.

                          But I bet someone will have a different opinion as well.

                            Ok now I have a plan. I still need to look into a cam. Anyone have a particular manufacture that I should look into?

                            Thanks everyone.
