Carl well done with your result. I myself was interested how your car sounded as i believe i have very similiar headers on the way. Hard to describe pretty normal when on idle then as the revs raised it was a very strange rasp kind of sound then all hell broke loose it sounded awesome.

Had my car back yesterday - including the RR figures from Friday.....

Started as a 98UK, with td04 ....

K+N 57I induction kit
Prodrive Grp N Silicon inlet hose, with no D/V ‘T’ off –
Power steering reservoir moved and fuel lines under inlet manifold ‘adjusted’ to allow fit.
TD05FE (early WRX TD05+Martin Fox FE conversion) Turbo
Hybrid fmic
I/C hard-pipes are wrapped
Ported headers (wrapped) – provided/fitted by Jap Innovations
TSL up-pipe (wrapped)
TSL Grp –A downpipe (wrapped)
TSL 4” Grp N back box
TSL decat exhaust centre section

Power FC ECU +Andy F Maps, set for Optimax (always)
AVC-R Boost Controller Running 1.5bar->6k, dropping to 1.4 bar
550 injectors with phase 1 adaptors
255 fuel pump
FSE regulator
PFR7B Spark Plugs

Cold Air Feed Fan, mounted in hole in inner wing to duct air when stationary
O/S wing brake feed modified to vent air onto disc and into inner wing
Reflective Air shield around Filter (Made from Transmission Tunnel Heat Material)
Breathers joined and vented, via filters, to air
Left bonnet scoop replaced with mini-airfeed scoop over induction kit
removed dumpvalve
airbox resonator removed in front O/S wing
remove undertray
Carbon canister removed.

All wrap is cool-tek, from Agiemech

The boost graphs shows 21psi held from 4K revs, up to 7K, but I know it holds slightly more on the road (which is nice )

Thanks To AndyF for a fantastic map, and to ScoobyClinic for looking after the car last week -

WRT the mod to the turbo, sounds like its a smoothing off of the compressor housing, where the air inlet pipe (induction side) attaches ?

Guess this is to aid the airflow into the turbo, to save trying to compress 'tumbling' air ?

I've seen some pictures on 22b in the past - think I'll leave mine asis for now, as ultimately I'll be replacing it with either an 18g on this engine, or '?' on a 2.5.....

Mark, I'm thinking about that mod on the turbo with mine but I've some doubt about surge issues. With the Samco inlet pipe I may need a little restriction to reduce the possiblity. I need more people's experiences first. There's a turbo tuning site in the US that ports turbos but they don't seem to do the comp i/l, is it for this reason???

Just got back - in from the hill climb practice weekend, but WELL DONE to you Carl.

Great when you get there!

Get that 20g and you will NOT regret it

Set the next level HIGH!

well done all on the figures..!

How did you go G?

Mark, is that std. UK internals?

April 23rd for my next RR but GT spec headers went on today, blew the lambda boss plug out on the drive home, sounded like a diesel tractor , thought I'd killed it.
plug was only wound finger tight so had to screw in a spare lambda probe.
Hybrid fmic being ordered in the morning and hard inlet in the pipeline so to speak.
Now, how to relocate the PS reservoir?

911

It's all on my thread now.

wish the engine would tick-over!

What a fab car!

Ballistic!!

Sorry, Graham.

markwild

Andy, yes that's standard UK internals - (assuming you meant me..)

I've had the D/V plug blow out once - NOT a nice effect when you're overtaking a lorry !

Peanuts

new headers will take a little while to get used to...
previously the noise of the car was predominantly from the front, resonating like billy-o through the cast headers.
Now the tubulars are on the noise has noticably shifted to the rear of the car and is coming from the silencer area.
Bought a H&S 3" downpipe from Dark Blue Mark on saturday morning as well so thats got to be wrapped up and fitted with my new wide band lambda

keep up the good work all

Thank you gentlemen, had a lay-in this morning.

Headers wise i'm not 100% sure they aren't reverberating through the engine. I did notice the RH bank came very close to the sump. When i take the turbo off next time home i'll try and edge them forward slightly and see if it makes a difference.

Thanks to Dougster again for a vid of my run, i know the plate's still there but if you're keen enough to download 38Mb (!!) you deserve it lol.

Nice result Mark. I'm trying to draw comparisons between our cars, yours is obviously running a Hybrid FM, Prodrive Inlet and an extra 0.2bar of boost whereas i'm using Octane Booster and have tubular headers rather than ported cast headers. I would have expected the FM and extra boost to make more of a difference but i suppose we can't read too much into results on seperate rollers. Thanks for posting everything up though.

As for next steps i really don't know tbh. Immediate future is to have the turbo checked out and experiment some more with charge cooling mods. If i'm going to go further with this car i know there's roads i don't want to go down. i.e. a front mount just doesn't appeal and nor does spending 2k on a 6-speeder if were to push the car that far. The temptation to recoup the money i've spent is very strong, selling the mods + car seperately while keeping the tasty bits should see me 7/8k up which with a house to buy/furnish in May appeals strongly. I'm only 23, plenty of time for new projects, 400bhp STi 5/6... 350bhp MY05 STi with decat, filter + remap...

We'll see what happens, i'm offshore on Tuesday so two weeks to think about it. Suggestions on a postcard.

Does exactly what it says on the thread title ©Ronseal



well done Carl and stick with it, you know you want to

Andy.F

Wise decision to call a halt at this stage on a 97 UK car in my opinion. The newer a car you buy the less money they need on mods to achieve the same power.

Andy

markwild

Andy, I admit that I'm surprised to hear that. Is this based on the fact that the next step is expensive, or that its specialised - e.g. fitting a 2.5 or replacing the internals ?

At the stage I'm at, I feel that I should either sell up, replacing the 98UK with an 03sti or newer, and start again, OR fit a 2.5 to mine - tbh I've really decided to take that latter path, as I think a) it would be cheaper and b) I get to keep the existing car..

Also, in order to get the same power/driveability/reliability as a 2.5, surely I'd need to fit the new car with a 2.5 also ?

I'm guessing that, if you don't want to take the 2.5 route, then a newer car can be lifted to more power more easily/cheaply than an older one, which is giving rapidly diminishing returns ?(Hence your comment)?

Mark

911

I think there may be here.
The blob eye has big brakes, 6 speeder, a stiffer shell (heavy though) and better suspension, plus several things I don't know about.

Take the 6 speed = £1500 at best + fitting maybe
Big brakes, another £1800 on top, same for the suspension mods?

I find myself looking at the costs to go further too, and the box/brakes are soon needed, then the 2.5 which would need to be 450x450 spec to be worth it. You need the box/brakes for the engine.

My Sti v3 has already cost about £18K and it's all been DIY except for Andy's work.
It is a quick car, still a 1996 Sti, and to go further is another £8K for a very fast car.

If it is any consolation 911's are just the same 'game'.

To get the value out of the expense you need to keep it for a long time. I've had the 911 for 16 years now...

My main concern is surrounding the transmission of the current car. The clutch is an unknown entity (make + mileage) and UK gearboxes don't last long at 340+bhp. If the worst was to happen i couldn't see there being much change from £1250 at best (V4/5/6 box, diff, clutch and fitted at home) which is a large percentage of the total build cost to date. At least with buying anything after a V4 in STi trim a more suitable transmission is already in place. Not to mention the engine, suspension etc...

Carl Davey

iTrader: (3)

Graham you beat me to it. Good point about keeping a car to get the value of the expenditure, the fridge certainly won't be staying with me for 16 years.

So the total cost of extracting a real 300bhp from a MY98 UK turbo goes something like this...

Engine Management

• £500 - Apexi PFC + Commander
• £350 - Fitting/Mapping/Re-Mapping Apexi PFC (inc. travelling costs)
• £0 - Apexi ACV-R

Turbo/Intercooler

• £250 - FETD05
• £260 - Re-cored MY00 TMIC
• £30 - MY98-MY00 TMIC Dump Valve Adaptor
• £63 - Samcos (inc. cost of new s/s jubilee clips)
• £36 - Zero Sports TMIC duct

Exhaust

• £175.51 - Megan Racing Headers
• £68.95 - Cooltek Exhaust Wrap
• £7.14 - Agriemach Exhaust Paint
• £5 - Jubilees (to secure exhaust wrap)

Induction

• £50 - K&N Induction
• £10 - Ducting for Filter & Hose for Boost Solenoid
• £5.58 - Insulation

Fuelling

• £185 - Walbro 255l/hr + FSE Reg
• £70 - Phase 2 440's
• £0 - Injector Adaptors
• £44 - 20 bottles Millers Octane Plus

Sundries

• £35 - NGK PFR7B Plugs
• £64.81 - Gaskets

TOTAL = £2209.99

I think that's definitely enough for now, i'm surprised i broke the 2k barrier tbh. I suppose if hadn't bought all-new gaskets (twice) and not bothered with things like the TMIC duct and Samcos it could've come in under 2k. Likewise, if i'd got it right first time there would have been no need for the re-map.

Well, i think i've proved with as much technical knowledge as is necessary to tie shoelaces it's possible to get 300bhp from a dowdy 208bhp UK Impreza. Whether £2200 can be classed as a budget build i don't know...

Excellent thread - paves the way for the many of us UK turbo owners on here

Is there any chance you could list the items that you bought but then -

- Did not use
- Replaced
- Believe weren't that useful in increasing power.

Could maybe save money for others on here thinking of similar mods.

Cheers

Craig.

markwild

Well Done Carl - I think you can class 2K as a good budget - mines probably cost twice that (With items like the PE ECU @650 quid, that have been discarded) !

iTrader: (9)

Well done Carl. I'm on a very similar mission but with a MY00.

Heple has a good point in that we sometimes buy stuff that doesn't work or we change direction and upgrade before really trying something. I know I have. I've kept a spread sheet of every cost and every transaction, so I know about all the swaps and trades to get to where I am now. The crux is that I now have a list of cost and items to get to my goal very much like you. The proof will be in the RR run to see where it gets me...

F

markwild

I must admit that I see my 'add-ons' as a hobby, so don't actually regret any of the spend - I certainly won't get any money back !

Having already spent well in excess of 10K, I'm not convinced that I'd get value for money by ditching it and getting a newer car - but I suspect that this is not the case for most.... add in the fact that I've never had a fixed target, simply a constant flux of improvement - and I'm happy with the state of things....

One way I have managed to keep tabs on things is to buy 2nd hand wherever possible.
The only things new are:
(iirc)

pump and reg. (ASperformance)
green cotton filter (now sold)
samco hoses (were they really worth it?)
SPA dual oil gauge (group buy)
and my whiteline bits (group buy)

my car may not be the best looking and the engine bay looks a but mish/mash (nothing matches etc) but I went for function over form and I believe that at resale (of mods) I will get a big proportion of my outlay back.

it is possible to keep things a bit cheaper and a well known/respected tuner said to me only this morning "many a mickle maks a muckle", how true!

Floyd

iTrader: (9)

Lol, that must be an Andy type quote

If you try to buy second hand, in many cases you will get most if not all of your money back, especially if you've bought the right and sought after bits. The only problem is that 'todays' sought after bits will be 'yesterdays' news as the game moves on.

I've sorta come to the conclusion that there is a point of no return. Where it'll be very difficult and costly to return a car to standard to resell it. Treat it like a hobby and not just a car to get from a to b and be happy with the outlay.

well done carl about time though
is a very good example of how to upgrade a car properly!!

as above anything u fitted which u felt did not increase the power?

what was the best mod u made?
