FSti stage 1

[Jim on the hill]

Evening chaps,

After 4 very happy years with the Foz I've decided it's time to look at taking the power up a bit. I currently have the 2.5" cat back from Hayward and Scott which sounds great but I'd like to have it mapped and the supporting mods added.

Info is sparce on the internet due to the rarity but I've seen a few people (MDMA) seem to be running some impressive numbers.

All advice welcome, 330 seems to be a safeish number to aim at but more concerned by Torque for the fun factor

So it’s a case of sports cat and map or just map , i have one of each there is little in it drive ability wise , i prefer the one with the standard cat , the sports cat one appears to have even less lag full boost is around 2200 rpm , 330 bhp is a good target , i did not do my fuel pump on one car it’s still running fine after 165k miles or so , the other fsti pump gave up at 85k miles and had to be changed , i would do a centre section delete more for noise than any thing else plus coil overs , if you do coil overs changing the rear arb has limited effect , coil overs work very well

Thanks, so I don't even need to do a filter or induction kit?

I can't really touch the suspension as I use the ground clearance a lot of the time.

Any reccomendations on mappers? I'm Bristol based so Bob Rawle or TDR agree both close enough.

[vxr2010]

You can run a panel filter like a k and n but it does not make much or any difference , you can do coil overs but don’t have to lower it , standard suspension is ok but not that sporty for want of a word , i’ve heard of both mappers but don’t know enough about them to advise, i’m sure either will do a good job , mpg will improve after a map if you drive sensibly i’ve had 35 mpg at 70 mph on a long run , the limiting factor is how much boost the turbo can produce , it’s around 1.3 bar max , but turbo works very well with the car ,injectors are fine with standard turbo , possibly/ probably do a fuel pump as above one pump ok one pump not , a map makes a lot of difference , due to a lack of turbo lag it’s like a scolded rat off the lights

[Jim on the hill]

Interesting. TDR have said that I'd need a decat, air filter, free flow exhaust including air filter and fuel pump to get to 320-330bhp.

That was sort of what I was expecting but I was hoping to retain the cat as don't fancy driving an illegal car. Hmm

[vxr2010]

I would at the most sports cat , i would not de cat , cat back system minus resonator , air filter very minimal , no harm in doing a pump but not always needed , and then see what you get , you won’t be disappointed , as i said a sports cat v standard on the road very little difference in it , if it was me i would just cat back , cars make different numbers dynos make different numbers , litchfield we’re doing a 330 bhp package maybe find some spec on that , but as above if i did it over again i would stay with a standard cat it appears to drive better

[Jim on the hill]

Thanks, driveability is the most important thing. Certainly don't want to chase numbers if the end result is losing the fantastic way it drives.

Who mapped your FSTI's? Incredible you have two by the way, some might say greedy.

[vxr2010]

Greedy yes lol , the guy who did one no longer does it that’s the mrs car , mine was Richard at FB tuning , he is very good but not that local to you i think , the pump situation they can tell you when mapping if you actually need one , waldro is a good route to go , so i can’t really say yes you will need one no you won’t as only they can say , if cars done a fair amount of milieage say 80k miles plus, maybe worth doing as that’s when mine started going , i sold my jdm sti wagon , i still have a 5.7 440 bhp had a 6.2 500 bhp in the garage , the cat that’s a bit of a yes no too , i think for the money you pay v a bit extra bhp is it really worth it ? if you do do the cat don’t get a cheap one as they can fail , the good side with the cat boost comes in slightly earlier a bit more in the way of boost noise , but back to back on the road very little in it , a quicker reaction at a set of lights is more significant than a sports cat

So after trawling my emails it jogged my memory that I added a Cosworth air filter already and I found an old email from Bob Rawle to swap out the pump and upgrade the spark plugs before the map.

A well known chap called Duncan of "Racedynamix" roadmapped my FSTi (and my modified XT). Seems to go very well!

I am currently running a Fujitsubo Legalis cat back and a Syms sports cat, after a remap at Slowboy I am seeing 321/350 at 1.4 bar of boost.

I completely agree with what others have mentioned, decat is not a requirement to get decent figures.

If its not too late....
Just email Bob Rawle and tell him what you are after. He is really helpful and happy to advise on any parts that would need fitting and why and what to expect from them. I have had 3 maps from him now all been spot on.

Thanks guys, I mentioned above I found the last email I had from Bob Rawle. Sparks and pump have been ordered so ready for fitting then mapping.

If one was childish enough, could they have pops and bangs mapped on to the standard ECU or is that a no?

[RB Will]

You might get a few natural ones but you will need a new ecu if you want the proper antilag like mine

Well, that video is just rubbing salt in the wound!

Thanks for the info though

You can adjust the idle timing and low end fueling to encourage it a little on overrun. However, the ECU generally runs a full fuel cut at 0 throttle.

It's possible to get rid of this, but you're into adjusting the software as opposed to just the map.
