Default 5 Liter w/ Turbo Build

I just purchased an 85 5 liter engine. I need to put an engine in my 82 turbo car due to a scratched/gouged cyl. that caused alot of blow by so this one will do.

It has the heads and cams installed but no intake or wiring harness. It does not have the caps and rotors that are supposed to be mounted on the cam gears. I already have a set of euro S heads and 78 cams that I have been saving for a hybrid turbo build but I never expected to buy a block with heads and cams intact. I would like to use the 32v heads if possible. Can I use a standard ( 16v) distributor since I don't have the LH stuff anyway? As for engine management I still haven't decided. I was thinking haltech but it may end up being easier and cheaper to just buy all the LH stuff I'm missing. Since I'm starting from scratch in that dept. could I use the 2.4 stuff so I get a knock sensor or would the wiring be a total nightmare?

I haven't recieved the engine yet so I can't just go out and take a look at it. What would you do.

Starting with a 5 Liter block you are one step ahead of my LH / EZF conversion since you can use the stock crank sensor location.

As for 16V versus 32V......the 32V heads are more boost friendly but building a ***** to the wall 16V is so much fun!!!
What are you power goals? If your goal is "only" 450-500rwhp a 16V will work just fine (with the proper engine management system - LH / EZF will work fine).

Start pricing out EuroS / 85/86 parts. I was able to score everything (including a harness, brains, and distributor) for around $500. If your shopping spree gets much over $1,000 might as well go with an aftermarket ECU. Unless you are already invested in a SharkTuner.

Thanks. That answers that question.

Thank you. I may take you up on that offer.

Yeah, I would be happy with a 450 rwhp package. At least for awhile.

I'll try to locate it and bring it along on Fri.

When you get this can you bring it over so I can work on it ?????.
Nice air conditioned garage to work in, and a chance to take one apart and practice!

Running the Euro S heads, on the 5L bottom will give you high CR. If you had an S4 bottom I would have said do it.

As well I would def go the standalone route.
Go with MAP and COP or EDIS-8 style.

MS is the cheapest, Haltech is good but prices get up there.

Thanks Lizard.

Does anyone else have any thoughts on engine management? I have found some S3 computers as well as S4 computers. I already bought an engine wiring harness for an 85-86 engine. Will this work with the S4 computers? If I use the S4 computers I will then be able to have the knock sensors, correct?

Thanks

there is alot more compenents like flappy and knock sensors and such that the S4 controls that isnt there on the S3. Im not sure there are the holes and such for the knock sensor plus the hall sensor, etc..........
Why wouldn't you just use the S3 computers? If you have the wiring harness etc... you are ready to go with the LH and EZK
Porken has both the LH and EZK maps figured out pretty well and will be able to provide you a wealth of knowldge if not chip help for your turbo. Mark also has success using the S3 with simple components such as RRFPR and/or piggybacks, im sure it will turn our great on the S3

The reason I'm asking is because the new cheaper Shark tuner is for the S4 not the S3. I would also like the ability to use a knock sensor thats integrated into the EZK instead of just a light. As for the flappy, I plan on using an S4 intake. Isn't the flappy part of that intake?

Who is Mark? Mark Robinson? I really don't want to use a piggy back. I will go stand alone before I do that. I would rather be able to shark tune. It would give me an excuse to buy one. FL needs one.

You need to tell me more than that Mark. Why won't it work? Do you mean it wont work with the engine harness that I bought? I can see where that would be true. Please elaborate on your position that it wont work.

The harness is completely different. though once you look at the cost of the ST engine harness etc. you could have done the standalone route with COP technology.
This eliminates the MAF caps rotors etc. Plus you just then need to plug the laptop in and adjust. Plus it is newer and will have less issues.

What is the difference between a cam cover for an 85-86 and a cam cover for an S4? I see that they have different part #'s. Will the swap from drivers side to pass. side or are they different in that aspect as well?

My engine came without these parts so that's why I'm asking.

Thanks
