well im going to be picking up a haltech i think it's an f9? plus a couple 720 secondaries



also a fmic (npr izuzu one)



Im doing this for reliability reasons, but with tuning and what not what kind of nuimbers should i expect from this set up? Also factor in a FCD+ racing beat 3" stainless turbo back exhaust.



And what other things would I need to pick up to complete this small set here(later in the spring im upgrading to a standalone but for right now im needing something so my car doesn't explode before then, and no, im not turning up boost or anything id just like to get "quasi" good gas milage)

Simply adding fuel isn't going to make your car any faster. Of course, the 3" turbo back will free up some horsepower, but nothing else you list is going to help the engine breathe any better. One way or another, you'll need to get more air into the engine before you can use any more fuel.



You could always upgrade the turbo once you add the fuel, though.



And I wouldn't look to improve the gas mileage over stock. If you're tuning for performance with a safety margin, its likely you'll be running richer than stock and consequently be looking at still lower mpg numbers.

Ya it kinda explains itself, more fuel, less air = less FPG(gas milage)

i figured adding a front mount would help with more air, but that's wrong thinking??



and im not looking for hp #'s at all, just the "not blowing **** up" margin.



outside of a new intake and my front mount what are some other ways of adding more air then?

Its an f5.



A front mount is really just gonna allow your car a cooler intake charge and allow you to run a much bigger turbo compared to the stock top mount would allow.



more air = bigger turbo



and for more air you'll need more fuel.





And how bad is your mileage?





I got 18 around town and 22-23ish on the highway with stock efi and 10 psi.

meh. kinda pewpy gas but i need my fuel hoses replaced, i need to do a bunch of things actually.



i'm going to need to make sure i get everything together on it right



by the way, what are your guys thoughts on the whole intake thing? is spending 149 dollars on an intake from hks worth it?

I have read in many places that the stock box intake is better than a cone filter. Only good thing with those is that it frees up engine bay space. Oh and e-fans run hotter than the normal clutch type fan.

Prelude intake pipe at autozone for 40 bucks looks shiney and has the right bend, you just gotta cut it and add a filter.



Or...you could home depot it and make a 3 inch TID for like 10 bucks.





Go search the faq section. I honestly couldn't justify spending so much for an intake when you can build your own for much cheaper, and you said you were considering getting a bigger turbo as well.

Veritas

... gimmie specs on it and i'll do that bitch up right now.



But what about the MAF? don't I need something for that? Like what's involved in taking it apart to do that?



And back to the FMIC, this shop is wanting to do my front mount for 450, 450 includes labor, cutting, fitting, and everything else needed for the custom **** for getting it welded up right. Is that a good price or is that bad? Im picking the NPR izusu one up for 280 shipped, would it be easier to do myself or just better to have them do it? I don't have a garage to do the work in so... yeah.

Pull the MAF off the air box, buy an adapter on ebay ( I recently sold mine, an HKS ) and put a cone filter on there. Bang for the buck, there isn't anything you can do to the car to make it faster. The stock airbox is a major flow restrictor. I think my 1/4 time dropped a half second on this mod alone. No BS! And I was already running a K & N panel filter in the box.



Front mount adds safety margin by lowering intake temps. Probably not a factor unless you sit in the staging lanes with the engine running. If you're running stock boost levels, I'm not sure I'd even bother. I'm running 12 psi with pretty much open exhaust and a cone filter right on the turbo (Haltech, no MAF), and I'm still using the stock top-mount. Granted, it's pretty much next on my to-do list, but IMO its an expensive PITA for a couple degrees lower intake temps.
