Should I get the Greddy FMIC or stick with the stock TMIC? Here's the dilemma, I'm on limited funds. Should I get the FMIC ($899.99) and HKS SSQBOV ($199.99)? Or should I spend my money on 720cc injectors ($110.00) and a Apex'i S-AFC 2 ($324.00) and stay with the stock TMIC?

It's an s5 engine.

 

stock top mount with water injection. and maybe an IC sprayer would be fine.

 

The TMIC is good for 12psi max on stock turbo.

You will gain performance with a SAFC. Why do you need 720s? Are you upgrading your turbo? What are your goals here?

I have no clue about your goals here but I am thinking Rtek setup.

If you are upgrading your turbo or planning on it with a bigger turbo, I would start building for that anticipation and go with FMIC. You should always build the platform around what you want, so that when you are ready to put the numbers down, you have a setup ready to handle it.

Oh yes you can hunt ebay and here for safcs for under 250$

 

Well.... I'd like to get to 250hp - 300hp. Let's say everything I have is stock. What would be the best thing to replace first? From what I've read the stock fuel system is fine so I shouldn't need to replace is except for the fuel pump which I'm going walbro. I have a stock turbo currently and plan to use it for awhile. Where should I start on upgrades?

 

300 at wheels or flywheel?

 

Wheels.

 

Won't get there with a stock turbo.

 

you might be able to make 250 with the stock top mount.

run 12psi on the stock turbo, get the injectors and the s-afc.

 

I figured I couldn't get 300hp to the wheels with the stock turbo... but iceblue said to build a platform. Bah.... I should just bite the bullet and buy the FMIC, injectors and the damn s-afc... do everything at once....

 

Allright, I suggest this injector setup. 680P and 890S this will be good for 385FHP at 85% duty. A safe range and subtract ohh 50hp for wheel numbers and you are right about on your mark. There is no way of getting around fuel management for these numbers.


1. Search for a stand alone EMS on here. You should be able to grab one $-500. The injectors I have above. A 3" TID, I think a BNR stage 2 may do it.

Now go to the dyno and see what you can get after tuning. If you are in your happy range :-D If not see how much more you want. Are you detonating? Will WI do what you want for $300 to $500? Or will a FMIC do the job? All up to you.

I suggest investing in some good gauges. Know you water temps and intake charges. I like EGT as well. This could help you in decided on your purchase if needed of WI or FMIC.

:edit: I forgot to add a FPR and pump. With large injectors and boost #'s it will be more dificult to keep your rail pressure up and consistant.

 

Go with the front mount and BOV. You can always buy more fuel and more injectors later, just keep your boost reasonable.

 

Well, fuel won't net you any power in itself... It'll just allow you to run more boost safely. BUT, you have to remember the stock turbo is only good for flowing around 12psi. So, in keeping the stock turbo, for the time being you only need fuel that'll support 12psi... I've got a buddy running the R-tek 1.7 chip, Walbro fuel pump and 700cc secondary injectors.

His car RIPS at 12psi. He's got the stock turbo, TMIC, 3" exhaust, cone filter, street-port etc.

You don't need the BOV right now, so I'd hold off (unless you really want the steez' points)

I'd say you don't need a FMIC until you're ready to get a turbo that'll flow more than 12psi and make more power than 250whp. Of course a FMIC has great benefits, but I don't think you should get one yet (unless you can find a really good price).

Make sure you've got the TID, full exhaust, ported WG, FCD of some sort and a decent boost controller (think EBC) before moving on.

I'd personally get everything all at once, but that's because I'm impatient and financially retarded...

Just some thoughts.

 

I already have the full exhaust and because of that I have the FCD and will end up porting my WG. I've never really looked into the boost controller. I need to do some research on this subject.

 

you don't need the high dollar BOV. Cheaper ones are available and most on this forum will fight to the death that you don't need one at all. I would how ever take car off fuel management. If you get the fmic you will hit boost cut and possible pop your motor. I would get fuel and fuel management going first.

 

ahhh soo many decisions... not enough time!!!! thanks for everyones help. I thought I was close to what I want but realize how far away I really am.... right.

 

I really would advice against teh SSbOV. It makes this really weird fluttering noise during gentle driving and the noise is small compressor surges. I think this might be unique to those with fmic. Because it dosent do it if you have a tmic.
