Looks loverly

 

It's a limited edition - one of the best limited editions that Subaru have ever produced. Its increased value lies in its relative rarity. Why are you determined to **** it up?

 

i cant belive this thread, hold on its my thread lol ,,, if you aint got owt nice to say dont say *** all , start your own and moan like *** on that one not mine

mods please delete this as i realy cant be assed

stu

 

I couldnt care less what you do to your car, just interested in why you would spend money on those things and what gains you think you will get from then when the stock setup is really nice with cheaper and simpler mods.

But hey ho, if you want to be all defensive and are not happy to have your incorect knowledge improved on then thats fine by me.

 

don,t take it to heart mate, some of their advice is good and therefore could save you money and heartache in the longterm. btw i prefer anthracite p1 alloy,s on the p1.
what state fo tune was your wr1?

 

incorrect knowladge get a grip mate , are you always right , if subaru made there cars right none if us would tune them

question for you ,, have you done any thing to your car ???

stu

 

A good point. If I was modding my car (again!) I'd certainly be interested to here Jon's views. Is he ever wrong? Probably, just haven't seen it yet!

Nice looking P1 by the way.

 

LOL Stuart you O.K. ?

seem to be taking quite a beating here................

I thought a FMIC was a good upgrade ? All the air doesn't even get in the scoop on these things after you get to a certain speed ?

Might aswell add: Type R > P1

Cars looking good btw

 

nice looking p1 mate are you local to lincolnshire still?

a friend of mine in stamford had one so i will warn u now uyou will get a new name of Stu with the p1 "you know stu? stu with the p1"

i hope u enjoy it mate and make it your own

 

I usually am on these things yes

Sure i've done things to my current car, as i did with my last two STi5 Type RA Ltd's too, I make the changes i do based on sound reasoning though. So i asked the question why, to try and determine if you are wasting your money and making the car worse, or if you were looking to increase power enough to warant buying what you have.

So why do you want a FMIC and headers? they are going to slow the spool down and really arnt worth the cost or agro unless you are going to tune it beyond the stock turbo capabilities. Aftermarket headers are a waste of time and money for most people, you get better response from porting the stock headers at mild tune levels, most aftermarket headers are too big and loose you spool response.

As to the TMIC not working at speed, rubish, i used to do hundreds of laps of the nurburgring at high speed with a charge temp guage on the dash, stock TMIC is fine at resonable power levels. I've driven new age Time Attack cars at over 500BHP on a proper race core TMIC's, there are a lot of myths out there about the airflow through a TMIC, they have lots of benefits over a FMIC, especially with regards to engine response.

 

Stuart the above is good advice.
Port and wrap the headers. Harvey up-pipe. Put a decent panel filter in - say K&N (I am Incorrect See Post below) GroupN filter
Spend money on more mapping.

Perhaps, an idea and each to there own. I would quite enjoy taking it back to origonal condition and turning it back into a ´´classic´´ Find a spoiler, the right wheels a VF28 ect

If you are going down the modified route I would spend your front mount and tubular header money on bigger brakes.

Perhaps spend money on putting it back on to 17s - as they handle better on 17s than 18s

Dont use a K&N on a P1 or MY99/MY00 of any kind, they destroy the thin film MAF sensor. Best panel filter for that year is the genuine Subaru GroupN item, flows plenty enough air and is designed to run with the 8Krpm engine limit.

 

Is that because of the oil in a K&N green filter

 

iv got a itg one in mate , i do no a little about cars mate this is my 6th subaru , iv had mr2 turbos and evos mate

the mods i do now are all to benifit later , just thought id get them now because iv got a little extra cash

once i save up im getting turbo , injectors , clutch

im not getting snotty mate , but i only put this up to let the last owner know what im doing like i said i would

Yes, you should use a dry filter with that MAF.

Sounds resonable then Stuart, dont expect it to be as responsive whilst in the lower state of tune. It's worth checking the headers diameter, you can get a large variety of setups, thelarger ones are hopeless until you get into serious power levels.

 

That looks like a nice P1 and I have a soft spot for these cars. Probably the best Subaru that ever came direct to the UK market. As pointed out by Fatboy about 40 posts before these care are unusal in the UK in that they have STi 5 or 6 gearing with 1.0:1 drop gear whereas most UK cars are 1.1:1 drop gear. The P1 enjoys a 4.44 rear LSD and .738 5th gear.
Bad move but I suspect you are joking but that level of boost can be run with proper Ecutek mapping.

Your VF35 turbo is capable of around 340 bhp with all supporting mods properly done and modifications that compliment each other. Your O/E injectors might just get close to that power output. You do not want to go beyond 340 bhp without an efficient FMIC which the Hybrid is (HDi). We can actually show that there are gains to be had from around 320 bhp on the version 5 and 6 cars swapping to a front mount.
Your best option for headers with the VF35 are ported OE headers DEI heat wrapped with a matching stainless steel uppipe and the results from my header sets both OE ported and tubular with special uppipe are well known.
Unless you are going for a significantly bigger turbo, ported headers and matched uppipe will remain your best option.
What tubular headers have you purchased?
I would retain the panel filter all the way to the extent a VF35 can operate at. From testing we know there is nothing wrong with the OE Subaru filter but it does clog up within 3000 miles in average conditions. I always use a K+N panel filter simply because it can be reused with their cleaning kit. The K+N panel filter is preoiled by the factory and I do not accept it causes problems with any MAF sensors even fragile version 5 and 6 MAF sensors unless a numpty over oils it. As regards filters from extensive testing the filters that produce most power are the most open mesh and therefore let in particles the size of sand grains which is the reason we discounted the HKS green foam filter and all the steel mesh filters. The OE and K+N do a good job of filtration and produce good power. The STi panel filter which is £60 and disposable had the best filtration but produced least power. When I say most power or least power the difference was less than 2 bhp over all the filters tested but the ability to filter properly was a cause for serious concern.
Stuart: If you want further input or to benefit from my experiences on these cars of which we have done many just ring me, PM or email.

Generally you can take the P1 close to 400 bhp on O/E engine and gearbox with all supporting mods, obviously adding power will reduce component life, mapping is critical and if you plan to go further an ECU such as Simtek is a good investment at an early stage, not least because it dispenses with the MAF sensor.

 

thanks harvey , could you send me your number as i need a fmic as this one i bought as bits missing ,so cant fit

stu

ps, how much do you charge for a set of ported oe headers and up pipe ?

 

07860 302020. Mon-Fri. 09:30-16:00 and 17:30 to 19:00. Not outside these times please.

Ported headers, DEI heat wrapped, new stainless steel, slip jointed, purpose designed uppipe with five new Subaru studs, DEI heatwrapped £369. We will fit for £75.
There are six uppipes in the two bolt flange range as one uppipe cannot cater for all turbp/specification options. I need your turbo and main mods at time of order.
There are two uppipes in the three bolt flange range. (not applicable to what you are doing. For tubular three bolt header sets only)

will give you a call tomorrow if i get chance :-)

 

nice car mate.im doing the same as you.front mounting my p1.harvey is fitting it as they did such a good job last time i had one done.hes also fitting my turbo.

 

so what else have you done to yours mate .and what power you got ?

stu

at the moment its got a 3" turbo back exhaust,tubular headers and uppipe and a panel filter.its a fully forged 2.0 and built to handle 450bhp.i have a harveys hybrid fmic,induction kit,lateral injectors and a simtek from jgm all to go on before simon maps it.ive got an 18g sat at home to but im going for 400bhp so im looking for another turbo.since ive owned the car(less than a fortnight)ive put on 18" alloys,crystal pack,sti rears,dvd player and whiteline arb and droplinks

 

at the moment its running 320 bhp and 315 torque.mapped by bob rawle on the vf28
