I'm going to be looking for a FD towards end of summer/fall. I've been working on a setup that will suit the needs I have of the car and also so I know how much money I need set aside for mods.

First thing this will be a second car for me I'll have adaily driver and this car will only see the elements when the weather is nice. I don't plan on going single turbo because I want the quicker spool up time for a track type car however I do want to mod it enough to get into low 12's maybe high 11's which I believe would be about 325-375rwhp.

Anyway this is the set of mods I have right now if anybody has any suggestion why I shouldn't use a certain mod please feel free to comment.

Radiatior - Fluidyne
Intercooler - Blitz SMIC
Downpipe - Pettit SS Downpipe
Intake - Apexi Power Intake
Exhaust - SP Catback
ECU - Power FC + Commander
Stock Hoses replaced with Silicone ones

Obviously I'll need a new clutch for this and I plan on getting a light weight flywheel along with it. I'm guessing a new lsd will be necessary to because of the power I'll be putting down.

The questions I have are what type of fuel upgrades should I do with these mods? I imagine a pump and new injectors. Question is what pump is best? And what size injectors I know the ratios need to stay the same but I'm not sure on what injectors exactly.

As far as AST goes as far as I understand it doesn't seem to make a difference if I eliminate it or replace it with a more durable one?

I also plan on going with water temp, boost, and a/f gauges of course.

Anyway I'm just trying to get it setup to be a nice weekend cruiser with some power but hopefully it won't break down on me to much. I'll upgrades brakes as time goes by but the above is what I plan on getting in the car pretty soon after I buy it. Basically trying to get the engine setup perfectly and then I'll go and do the appearance mods such as paint job, rims, and 99 spec etc..

You're stock clutch should be fine. You won't be making that much power. And I don't remember Apexi making a CAI. sounds pretty good otherwise

Mike00

SOme of the questions do where do you think I got al lthe info above.

The fuel pump I've seen the supra mark IV one gets used a lot but I've not seen where to get it. I've not really seen any comments on what injectors work best at what hp.

AST wasn't a real question as far as I can tell won't matter what I choose to do.

As for the actual setup it's better to get comments on what mods work best with each other. For all I know for instance the intercooler I chose isn't the right one to go with.

jdhuegel1

Oh... You won't need more fuel. Just keep the stock boost level. (10)

Mike00

Stock clutch is rated at factory settings so shouldn't this cause it to end up slipping pretty quickly? Especialyl if I'm boosting at 12psi? Which as far as I can tell with the cooling and fuel system upgrades shouldn't be a probelm.

AMRAAM4

I believe he means the Apex-i Power Intake

Mike00

Yah Power Intake I put in CAI out ofh abit.

With the mods you have listed, boosting to 13psi will not be a problem. Stock fuel pump will be OK. The stock clutch will wear quickly. Don't worry about replacing it until it starts slipping. Get a light flywheel when you do the clutch.

The apexi is not a cold air intake. It is a hot air intake. The stock airbox can be modified easily, and inexpensively ($70), to perform like the expensive boxes, and you can still pass smog. Info here:

Mike00

Yah I'd rather just go with a new intake I think though.

I can't seem to judge how much whp that will let me put down any ideas give or take 50hp or so?

Finnally any other mods you think that should be thrown in there? Depending on condition of bushing I just might redo all of them to.

Also thanks a lot for info. The sites and the searhc only get you so far wanted a little more specified info on certain things.

jdhuegel1

Honestly? You'll gain MORE horsepower from Adam's mod.

As for the clutch, it will wear, but if you aren't doing 5-6K dumps and you're just weekending it with the occasional heavy foot, you'll last a while.

Thank you

Mike00

Well i nthat case I suppose I'll do that thanks.

Kind of surprised the fuel system doesn't need to be upgraded at 13psi.

ANy other mods you would suggest then Adam? particularly somethign to add power but keep smog legal? So no MP for me.

jdhuegel1

At 13psi, I'd at least do a pump. Just to be safe. Both the walboro and Supra pumps are popular. The walboro 255 can be had for 89 bucks on ebay. They prefer to be ran at a constant 12v, which is an easy do.

An Efini y-pipe is a nice addition, and smog legal too.

Edit: You will probably need a boost controller. I have heard that the on on the Power FC is not the greatest.

Mike00

It's funny Power FC seemed to be used a lot but now that I think about it I think it was mainly the ECU. What boost controller would you suggest over the Commander then?

jdhuegel1

I'd recommend STILL getting the commander.. It's a GREAT monitoring tool. A manual boost controller is always a good start. If you go electronic, ProfecB.

rdavidsrx7

I am pretty sure that I remember readin that unless you upgrade injectors the stock fuel pump is just fine. I ran 16 psi many times with an open exhaust, intake, and with a completely stock fuel system and never blew the engine because of the pump or injectors not being enough.
PFC...good idea, no boost control bad idea, get somethin for that

p.s. where ya at in PA, it'd be nice to see a few more FDs around....

adam c

I agree with all of that.

If you are on a budget, get a manual boost controller. If not, the Profec B is a good choice.

Mike00

With Water Temp Guage, Boost Gauge, A/F gauge is it really necessary for the commander? Not neccsary but useful I should say?

Oh and I'm north of philly about an hour of the city. Langhorne/Newtown area so not far from you.

PVerdieck

If your going to be putting in a downpipe, get a ceramic coated one, like NTech, to further help you with head in the engine bay. Or you can get yours coated locally.

jdhuegel1

No, however the gauges are usually easier to monitor as they can be mounted in better view. But, if you can find a nice spot to mount the commander, then no.. the gauges aren't really needed.

Mike00

Last question is the Kaaz 1.5 LSd strong enough to hold up under the power I'd be putting out?

jdhuegel1

Not sure about that one... A stock TII diff is very strong, and popular among the FD crowd though.

NukeGenius

A lot of people put the Kaaz diff and some even leave it stock. Also, the y pipe you wont need if you go single. You could probably even get those hp figures off the stock turbos if you go with a stage 2 or 3 BNR or somebody else rebuilding them. Its up to you. Most people with single turbos go with a FMIC, but I dont know if that is more of a requirement or a preference per se. A large SMIC should probably be sufficient. The gages are nice (especially boost and water temp) even if you can monitor them with the comp because they can be read easier and quicker. If you dont get new injectors, i'd say you should at least send off the ones you have for cleaning and make sure they are up to the task, and the fuel pump is relatively cheap and is a pretty easy install. You dont have to drop the fuel tank like on most cars.
