anyone here wanna talk with me about SDS EFI, TWM throttle bodies, and a RB deletorro upper manifold.
I've got most of it worked out, now i've just gotta see exactly how to associate the SDS EFI. If anyone here is serious about intake mods to a 13b 6p please lets talk. I have some info to share and am looking for another opinion online before i start hasling local mechanics again.
If you can't gauge what's being done from the above don't worry.

ya i know a little about the stuff. I havent done it or one it. I do own a 48 ida. But what exactly are you thinkning about doing? porting? etc. injector size and how many? 2 or 4? I personaly like the SDS it looks simple and thats what i like. em2 is the one your looking at right?

Well, how much does the SDS EMS cost? a haltech can usually be had for ~$1K & i think it is a better EMS.. As for the intake manifold and stuff you want to run, why not run the stock 13B intake manifold and TB??? They should work fine with any after market EFI system..

al right so you take the twm dcoe style throttle body and bolt it to the delletorro upper mani from RB. you have now the deletion lots of crap, a nice flowing manifold with proper short runners and wieght it's still EFI not a weber. There are reasons to go this extra mile opposing the straight weber set up, my final being you can pressurize the TWM throttle body to 1 bar, so that's turbo ready with a programable efi (proper options on kit to match) and you're in business imitating the cartech turbo system for the GSl-SE. anyhow that's the jist of it.
sorry I'm getting tired
Associate the SDS EFI to the TWM throttle body minus injector bosses. Use the stock injectors and location for time being-add secondary set when turbo is ready. **** porting the motor it has low miles and I don't wanna take it out again. This is just a straight intake idea with minimal draw backs. TWM said they'd send me a throttle body without injector bosses if i prepaid before april- no biggy. The real challenge is figuring how to associate the SDS EFI.
no use of emulsion tubes oil. system stays same on intake, use a TPS ,MAP, O2 and EGT sensor to tune the fuel curve, no provision or need for EGT on the SDS system you'd want it for there for tuning. Again I'm tired I'll read it all again and think then come back

Why would you want to use the stock injector location at first? This is from the TWM website.
(Original equipment EFI systems are configured to meet very stringent emission regulations and to provide "soft" driveability characteristics. Positioning the injector as close to the inlet valve is beneficial in this respect. Maximum power however, is usually obtained by moving the injector away from the inlet valve.)

Ease of preliminary installation mainly. ever see the gains from switching from throttle body injection to direct port. Throttle body/plte injection is crap from my understanding, however again down the road when i need the extra fuel I can mount injectors up the runners to add to intake charge speed, for now though agiain this is considering ease of perlimnary installation.
