Ok sorry Im just full fo questions, Im removing ac and ps, should I still keep it though? Is this the selonoid looking deal that is on the passenger side of the uim?

An NA ECU will start and run the engine but it sin't setup to read boost and bigger injectors so you could use it to start and rev the engine and maybe drive it very lightly until you get a N332 or N333 ecu. I'll update my Turbo swap thread to include the S4-S5 situation better. You need a Turbo MAF because it has a stronger flapper spring, otherwise using the NA MAF will get you by again for starting and running lightly but it will over fuel the engine cause its not setup to read so much velocity.
The BAC has one tube that comes out the back of the thermo housing to the inlet of it, and then the outlet of the BAC goes to sort of the back of the UIM. In my case I got tired of that hose barely fitting in between wires, OMP Rod, and other shenanagans that I blocked it off on the top and bottom and then left the BAC coolant passage open. The purpose of having coolant go through the BAC is so it adjusts barely as the temp goes up. I didn't notice a difference though.

If it was my choice I would run the S5 engine premix to keep all the front on as normal, then change over the injectors and temp sensors and tps and then find myself a N333 ECU and have pocketlogger/Rtek mod the ECU to a Rtek 2.1 and go that standalone route all the while leaving out the hard work and still having all the freedom of building fuel maps, ignition maps, getting every sensor reading and having the choice to run a wideband O2 right into the ECU so you can log and then tune in realtime... all on a small PDA that stays in the car instead of a laptop But keep the questions coming BB. I'm here to help

Well I have decided on standalone, I hate piecing crap together to get it to work right, because in my past eexperience it never works right for me. And I got a lot of people already talkin the smack on the car so I want to get it done and smokin some hondas by next summer. So the plan is this weekend get the engine block into the car and order a haltech/microtech asap. Theres a tuner named Nick at a place in Denver that has a 94 and talks very highly of the Haltech/Microtech and the price seems very good on them with a harness right now.

So the plans/goals for now is to get the standalone in and get it tuned and am aiming for a little under 300 horsepower now. Im hoping with the stock S5 turbo running around 12psi this should be reachable. But this brings even more question(oh joy!). I am going to use the 550 primaries for now with 720cc secondaries. I am at close to mile high elevation so I dont need TONS of fuel. So can I run safely 12 pounds with those injectors?

on 12 psi and a walbro fuel pump you should be fine just make shure its tuned anything past 12psi on stock s5 turbo is pointless its just going to blow hot air

look in my sig off everything i had and i made a little over 300 wheel and wasnt that hard to get there but you will prolly need a FMIC

S5 tails are the biggest power adders in there I thinks. Well I got a Wally 255 already so thats good lol. I have been looking for front mounts and keep finding a lot of V-Mounts, this is totally off subject but how do those perform.

i am personally a fan of the front mount but others sware that the V mount is good due to both radiator and intercooler get almost equal amount of air but need to make custom brackets for the radiator and also make an undertray so the air cant escape anywhere... and

i also agree S5 is major power adder that was my first upgrade LOL

I myself did the S5 to S4 swap. I just ordered a Microtech and got done with it in a hurry. It was a tad easier though since the car was a factory TII. Premixing is not too bad.

Ok well its decided then, Im going standalone. My tuner wanted me to get a haltech but Im going to see if a microtech will work.

Chris Boots

I personally like Haltec EK6 for another kind of standalone. And building a FMIC setup is easy but just takes time

I got a Haltech E6K :-D Do the ebay universal fmic kits have decent quality to them?

TwEaK

actually yes the greddy knock off ones for about $400 are one everyone is going with since the real one is over priced...

Is there anything else to add to this list?
I don't mean to keep bothering you, but you seem to be pretty knowledgeable about it.

It's possible there might be some small modifications to get the S4 TII TB to work with the S5 TII intake manifold, but I know they're very similar. The S5 TB spacer should be retained too.

The turbo oil return line (attaches to front cover) should also be S4 actually, since the S5 mounting point is slightly different. That's the way it is on my own car: S5 turbo -> S4 return line -> S4 front cover.

Thanks man. I really appreciate. I'm still trying to figure things out.
