There are lots of items you can buy to give you that extra H.P. Just look at the vendor lists, visit their sites and spend some time reading posts of others here and on other sites as well. There is no good answer for for - you have to do your own homework to fit your needs. Once you find something that might work for you, post your questions here and you'll find good help.

One word of advice - Don't post anything that you don't want anyone else to find out about - your wife might have secret SVO aspirations as well and read about your intentions here!

4 basic guides that will help you get started with the "more HP" hunger.

1. Remove the stock airfilter box and install a K&N cone filter directly to the Vane Air Meter. I think the part number is 0930, but I'm not totally positive

2. Remove the stock Boost Control Silenoid (BCS). It's located on the passenger side inner fender. Replace it with an adjustable Boost Valve. See http://www.turborepair.com/pages/sbc.html for the "Standard Boost Valve" or http://www.boostvalve.com/ for a cheaper less eye appealing version of the same thing. Set your boost at 18psi (or just below the overboost buzzer which is 17.5psi).

3. Remove stock downpipe (DP) and install a 3" DP. See: www.tinyavenger or www.svpu.com. They carry the good ones. Not all DPs are created equal. If you remove the CAT and continue with the 3" back to the tails (I personally don't recommend using 3" tails because of clearance issues) then you can see an approx 20 hp increase at the wheels. I picked up 17rwhp on my early 85 car with this mod alone.

4. Get the car in tune. New plugs, wires, cap/rotor, fuel filter, and PCV. Only use Motorcraft parts. NO aftermarket stuff. This is a serious comment. The little motor gets very picky when you use other stuff - even though it may be more expensive and thought to be better.

I would also suggest getting the Bypass Valve kit from TinyAvenger. Easy to install and it DOES work. It releases high boost pressure off the compressor during shifts - in doing it cuts down on lag between shifts and helps prevent wear on your turbo.

I will second Bud's list, it contains all the "cheap" mods to increase HP. The only other thing I might add would be a fresh fuel filter and possibly a 255lph high-pressure fuel pump.

A lot of folks want to replace the cat-back system, but that isn't needed until highter HP levels. The factory cat-back dual exhaust on the 85.5-86 models can support up to 270hp w/o restriction. I tested this on my 86 and found that my MPH on the dragstrip didn't change any with it connected vs. w/o when I was pushing about 270hp (99-100mph trap speeds). Good luck with your new toy!

Thank you for your input. The car currently has the K&N filter on the VANE meter, and also has the adjustable boost controller in series with the factory one. It has a pit bull cat back on it as well. I used all factory ford parts in the tune up with the exception of the plugs. I used NGK V-Power non resistor plugs. The boost controller is set at 15 PSI. I will bring it up a bit. I have already ordered the compressor discharge valve fron Tiny Avenger. I was thinking about the full cold air intake system. Will that help more than the K&N attached directly to the VANE meter? As far as the down pipe is concerned, I thought about removing the factory one right at the turbo outlet and having a 3" one made with the bung for the O2 sensor. I talked to a shop here that says he can do it and it will be mandrel bent. It will have no cat. I will retain the stock one for emission testing. What's your thoughts on an adjustable fuel regulator and setting? Also, I've heard a 190 GPH and a 250 GPH which should I go with? Thanks a million turbo lovers.

BTW, here it is. I only paid $4900 for it. I think it was worth it. See you at the SVO meet in October.

I just did this mod Yesterday. I did not have any noticable HP improvements. Next time I dyno - I'm going to try it both ways (cone filter on the VAM and Cold Air Kit w/ filter relocated) and get some factual data on it.

As far as the down pipe is concerned, I thought about removing the factory one right at the turbo outlet and having a 3" one made with the bung for the O2 sensor. I talked to a shop here that says he can do it and it will be mandrel bent. It will have no cat. I will retain the stock one for emission testing.

Just so much easier (and cheaper) to get one that's pre fabbed....and STAINLESS. See www.svpu.com or www.tinyavenger.com

What's your thoughts on an adjustable fuel regulator and setting?

Well - I would suggest getting one (kirban is good one) - it's th next step after the basics...and it goes inhand with the larger fuel pump. Setting will depend on YOUR car. There's a middle ground of 38-42psi with mostly stock motors - but this is really something you'll need to fine tune on your own.

Also, I've heard a 190 GPH and a 250 GPH which should I go with? Thanks a million turbo lovers.

There's what, a $10 difference between the two? Get the 250 - that way there's never a question if it's big enough

.

Btw, I'm usually in Marietta on the weekends. I keep one of my SVOs there as well. Give me a hollar sometime. Also - your picture didn't upload correctly. Please try again.

Sounds like a pretty good combo. The only thing that I would do different with what you have now would be to take the factory boost controller out of the circuit with the adjustable one.

The adjustable fuel regulator is a pretty handy item. You can use it as a good tuning tool especially when you add other modifications. Paul at SVPU sells the Kirban units that are very dependable. The ones from Crane and other people have been prone to leak.

On the fuel pump go ahead and get a Walbro #GSS340 pump. It is a 255 hi volume- hi pressure pump that works great on our cars. The other pumps for the V-8 cars fall off quickly at the high pressures that our cars need.

Hope to see you at the Reunion. If you can, come out to the SVPU cookout and go to the dragstrip with us on Friday night.

Here goes again. If it doesn't work this time, somebody, please tell me what I'm doing wrong. Thanks! I think the last file was too big.
