hey all looking to tune my wagon ... want 300hp -320 .. i have found it has these mods already.. 3" trust greedy zorst .. no cat still has standard downpipe tho. Has a td05 turbo , z4 prova tuned ecu ,k&n panel filter, blitz bov .. not sure if has uprated pump ..how do i tell?? looking to fit a fmic car has really short ratio gearbox with a super smooth shortshift ,doesnt look like a kit looks factory did any classics have a shortshift /short ratio box ? have recipt for £700 from previous owner ..had a 98 uk before this 4th and 5th r so short in comparison dont think would do much more than 130 tops what g box could it be , my m8 reckons ra of some kind ??? from my stuff already what do i need to do to achieve my target of 300 ish for now??

 

The cat should be in the downpipe, and JDM's only have 1 cat anyway
So your car should have a td04 Turbo as standard so its been upgraded from that, you could go for a full decat (remove the standard downpipe) and then remap again, 300bhp wont be a problem, and the gearbox, well to be 100% sure you would need to find the gearbox number, but sounds like a RA box if it runs out of steam at 130mph, plus get the brakes sorted, 2 pots are useless, my astra 1.9cdti has better brakes!

Mate, if its a 95 import then a TD05 is standard.

 

Yeah with the addition of a FMIC and with the mods on there already, 300bhp is there for the taking. The 380cc injectors will be getting a bit heavy on the IDC though. I'd defo get a decat downpipe too (£60-100), and some 440cc STi yellow injectors (£50-60)... Then it can be mapped to c.320-350bhp!

You know it makes sense...

 

Wagons run a TD04 as standard on WRX imports UK wagons (preface lift) on the other hand ran TD05's weird!

cheers lads ..think already has the 440s they are yellow top feed ?? car may be quick cant tell as only had a few days used to bein passenger in my m8s spec c ra wiv 400hp .. im just comin back to scoob s.. had a spell wiv sr20s and coupe 20vt s .. needed a family car so got a wagon lol .. it pins u in the seat but its so quick thro gears hard to tell?? does brake traction easy tho if u pin it out of a corner on not racing my m8 as last time we raced i was in his old v7sti wiv 420 hp he was in the ra , ra was gone but when v7 finally came on boost i was on him to cut a long story short the sti had been stood for 3 mths his mum had put **** fuel in it last time she drove it , car had been standing so fuel ron was even worse as we hit 160 it fried a cosworth piston .. was a horrible lesson for us both .. all on a pri road i might add ! i have been paronoid of scoobs ever since as that thing was bullet proff but it was the fuel that killed it not me lol

 

I am running a stock standard 95 with TD05 as factory.

 

Then you either have a new engine or an upgraded turbo either way it should be a TD04 as standard running 220ps

Tony

 

^^^^correct^^^^

the only way a import wagon wrx is running a tdo5 is if its been changed at some point in its life.

 

hmm have since been told saloon s 95 jdm td05 wagons td04?????

 

No chance guys, standard car with 260ps.

 

You have an STI wagon, not a WRX wagon as per the OP so yours will be different

Tony

 

as my car has the td05 ..and yellow 440s will my car have had an uprated fuel pump fitted in japan wiv the prova ecu??? how do i tell?????? thanks again guys

 

WRX's, correct

Tony

 

Oooops, my bad. I knew she was standard with the TD05. Are we sure the OP does not have a STi too?

 

Definately says wrx wagon, would be a pain if it were an STI

Tony

 

I got caught like that, bought mine as a WRX, got home checked the vin codes etc and found it was STi! You can imagine how stoked i was.

 

Bargain if you paided wrx money for an STI

Tony

 

Took k&n panel filter out today to clean, found half a corn field inside was completly blocked every small channel full of bits of straw previous owner been showcasing in a corn field me thinks lol would this affect overall performance?? was smelling rich cold start petrol smell.. first mod this wk end millers cfs 10w50 and diff oil change .. do i keep td05 or change to a vf series turbo as i know of a few about cheap ??

 

Yours is an STi though isnt it?]

EDIT: just read the above lol

 

I run a PP chip, fmic, de-cat down pipe and a dawes device, with a td05 1995 WRX Saloon. Got 303bhp / 290 ft/lbs. The dawes device set to give me the 1.1 bar the chip should have given me but was not quite getting there. Could probably eak a few extra ponies with a dawes tweak but would probably start to run a little lean on the 380's. At the moment still slightly rich (which is a charachteristic of the PP chip, rich to be on the safe side).

That's the final figure I am going for with this car (until the missus isn't looking and a forged engine just appears one day )

And before anyone asks - got gold Brembo's to replace the 2-pots

 

My tuned '95 STi wagon...forget the fact that yours is a WRX the parts to get to 320 are the same

thanks guys .. nice motor 53wrx!

 

still power hungry lookin for 350bhp ... mods so far td05 16g .. uprated fuel pump 255 .. fmic on the way full decat 3" 440 cc injectors.. 3 port boost solinode .. z4 prova ecu... equal length headers .... standard sti d.v ... i can get a 6k ecu if this better??? gearbox ra and ra diffs will this handle the power when all done ? will this amount to any where nr my target ..help please guys

 

Nath, I'm guessing the Prova chipset in your ECU casing is non-mappable? And I'm also assuming you have a 1995 car (Wagon) with the "phase 1" coilpacks-on-plugs motor? I also assume you've bought a replacement TD05H 16g (because a MY93-96 WRX Wagon has the small TD04L as std)?

If so, you'd need to get a cheap(ish) Apexi PFC or ESL Live mappable ECU to replace your current ECU with and get all those mods listed mapped. You should defo get south of 350bhp if you have V-Power in the tank when mapped. My only 'concern' is the 440cc injectors; they could be squeezed a bit! Personally I'd stick some 550s (or greater) in there, so you'll KNOW there'll defo be enough fuelling. It'd be a crying shame for the mapper to have to hold back on the power because the 440cc wouldn't allow it, etc.

Yep, so 550cc+ injectors; an aftermarket ECU; remap on V-Power, and you should be somewhere near your 350bhp goal. Don't forget you'd need some form of IK kit with cone filter too.

Your green label MAF should be okay for that power -- I was at ZEN's earlier on in the summer and some chap was having his 1995 RA mapped with a big turbo/FMIC, etc, and it made 387bhp! on the OEM green label MAF. Indeed it was his MAF that prevented him from getting more! (If he had fitted a Z32 (or Q45) MAF then, IIRC, I think Paul said the chap's 'unknown' turbo would have made about 420-450bhp!!!)

 

cheers bud.. car has tdo5 h fitted .. can poss get hands on link management for a gc8... also my m8 has some v7jdm sti pink injectors can these be made to fit?? think they 550cc...my car early phase coilpack...i always roll on vpower.. in my cars ...prova chip dont think mappable.. but i have a spare socket in board?? 1 of my friends runs a nr 600hp classic jolly green monster maps this think will get him to do the wagon ... they runnin solaris management that is an amazing bit of kit .. wish i could afford that .. what pwr am i maxxin internals for a wrx at?? also can get hold of pretty much any version heads what would be best combo ra/sti cams ect many thanks nath

 

I'm certain the Prova is just a non-mappble chip running about 1.1bar.

By all means fit a mappable ECU of yours/mapper's choice - and if MAFless then so much the better, as you won't have to worry about MAF failing and running lean (although it's rare on the early phase 1 MAFs). Also, it can't contribute to potentially hinder airflow by going MAFless.

Not sure if a 2001 STi has top feed or side feed injectors(?). You need side feed types... And yeah, 500cc+ will easily be able to net 350bhp.

You don't need replacement heads/cams for 350... Unless, of course, you're looking to future-proof for more power later...

 

Just stick to upto 350bhp and similar torque - as otherwise your std "TY752..." 5-sp, 4-bolt gearbox (the 'weak' one!) will be very much on borrowed time (depending on driving style). Don't forget your 'box, if original, is now at least 13y 9m old!!!

 

joz no worries there i am runnin an ra box diff setup ! previous owner did this a week after imported .. thinks these are stronger my m8 said r160 or 180 diff cant rem which .. 350 it is 4 now .. in nr future lookin to get a closed deck block arrow rods, cosworth pistons i know of 1 coming up soonish he going 2.5 .. then i have reliability ,its all in the mappin tho aint it !
