turbo stroker question

[john c michael]

I am sure this has been asked many times and i apologize for asking it now but for some reason i cannot open the recipes page.

i am looking for the best set up for my stroker. i am planning on building a 4.6 or possible a 4.7 with a turbo to be added down the road. i would like to get the compression ration as high as possible now without preventing a turbo in the future. It is not my daily driver and octane is not an issue. i would like to keep my budget under two thousand (not including the turbo of course). Any info or opinions welcome.

There's a link in my sig. to the recipes. Hope that works for you.
The 4.6L low buck recipe with a low pressure turbo (5psi) would be a nice set-up. Since you won't need much turbo boost, you could select a smallish turbo that'll spool up at low rpm to improve response and minimize lag.

thanks that looks good, however it raises another question. I have a early 90's engine but will be using a 99 intake so which injector do i go with?

Stock 8.7 to 9.0 maybe 9.25 CR. Injectors depends on boost, intercooler or not, what fuel pressure you will run and how much HP do you anticipate.

The compression ratio also depend on that fuel you should run on.
My setup is a 4.6 stroker the only thing i didnt do is milling the block.
If you should run on higher turboboost you should not bore too much in the cylinders because it degrees the wall thickness.
Here is my build I run 2 small turbo too get power in low rpm.
I runs it on 730 cc injectors with Megasquirt V3 E85 fuel and 1.2 bars turbopressure and also have convert it to CNG and hydrogen

Here is a picture i have taken for our CNG advisor.
For those thats not familiar in Swedish it stands "A Wheelie for CNG"

holy shit it is wheelie-ing!!! not high but still!!! nice

It could been higher but i have no stabilizer wheel yet and it's not nice for the powertrain to do a wheelie

nice set up thanks for the advice. one question what fuel are you burning in this pic?

[turbostroker]

To be honest it runs on E85 (Ethanol) because i have told the microcontroller to only runs on CNG in Highway speed because of the mapping I have now.
But the CNG advisor i take the photo to didnt now so dont tell him

[john c michael]

nice! i will keep that in mind for when i do the turbo since i got a E85 spot right down the street.
