what needs to be done

[poneyrunner]

i am thinking of doing the e block with a de head due to i have all the parts sitting here to make it happen.. the only concern i have is that with the higher compression from the e pistons what do i have to do tuning wise to make it work in my car? I currently have a de motor in my car can i run the stock ecu and just put 93 octane in it or is there more to this? thanks for any help in advance..

I don't know why you put 93 octane in a stock ka....there are no benifits. As for a tune you could run 93 octane. With the higher compression and be just fine. If you want to squeeze a little more out of it I would just get an e-prom tune from E-mance, enthalpy, or jwt. But even those companies only require 91 octane for there tunes. Get some 248 cams both intake and exhaust and port and Polish the head and sounds like a fun budget build.

im not really looking for alot of power.. i mean if i get some extra then great.. but see i have 3 motors 2 de and 1 e both of the de motors have a messed up botom end and the e has a messed up top end. i want to do a de turbo build with one of my de blocks but i want my car back on the road for as cheap as possible right now while i build my de turbo setup. so what i figured i could do was take the good e bottom end and put the de head on it just to get it back on the road... dont really car for alot of power just as long as it slides.. (its mainly my drift car) I know you can swap the heads with a little bit of modification and im just trying not to waste money in a motor that i dont plan to keep so i can save my money for my turbo build.. so i just wanted to make sure that when i put the de head on the e block and it raises the compression i dont need a tune.. i can just run it with 93 octane fuel and go slide it.. and have fun until i get my turbo setup ready..

What I would do is get your motor together and send the ecu off to get chipped for your current setup that you want. E-mance charges 175.00 for the service and chips . When you get your boosted motor ready since your ecu would already have a daughter board and chips. E-mance will sell you custom tuned chips for 50bucks. How much do you pay for 93 octane? That fuel is not needed unless you are extremely high compression or high boost.

^ You should probably know that in places over this way its either 87, 89, or 93. No 91.

man for 175 i can build my de back to stock.. the point is to not spend any money unless i absolutley have to. maybe some gaskets or something i dont mind.. but if i have to send the ecu off for a tune or even pay someone to tune it.. it then becomes not worth the time... i figured i could just run 93 in it and maybe retard the timing just a bit and call it a day..

Nope...never been your way. 93 here is over 5 bucks a gallon here. As for running. The stock ecu go for it. With the higher octane you should be able to run stock Ignition timing with that setup. Both ecu's sohc and dohc are tuned stock for 87 octane. And 175 bucks to rebuild a motor? I want your discount! Lol.

Figured. 93 is usually $.20/gal higher than 87 ( so around $3.65 currently).

s*** if it was that cheep here I'd run 12:1 compression!

well i build my own motors.. and do my own work... all really need to rebuild my de motor is rings honing and bearings.. and maybe a gasket kit.. parts maybe only about 100 and i can pay a machine shop to hone out my motor for about 60.. easy rebuild for under 200... and yeah 93 is only about 365 or so around here.. ok.. so all i have to do is put on the head.. and then just make sure i run 93 octane? sweet.. do you think i need to retard the timing at all?

[biggie]

Definately not that easy, but I don't know all the details. I don't think I've ever seen a head swap completed and only a couple times seeing the SOHC pistons used in a DOHC. Its just not worth the money/time usually.

[poneyrunner]

well if i had to buy the parts then it would not even be considered.. but since i have all the parts for free.. then thats why its in my head...

1) no need for more than one thread on the same topic.
2) anyone with hp goals as high as yours (400hp) need to seriously look into at least forged pistons
3) pick two ...... Fast, Cheap, Reliable.

i dont want to sound rude.. but if you notice they are on different things.. one was about if it can be done mechanically.. this one is about the tuning aspect of it.. 2nd... if you notice.. this is not my permanent motor.. this build is just to get my car back on the road while i build my nasty turbo motor.. I am trying to use my extra de block to build a motor for boost with weisco rods, cp pistons, balanced crank, and about 15-20psi of boost... this motor i am talking about in this thread is just strictly to get my car back on the road while i build up my money for the other motor for boost..
