tbh i think you need to go see a specialist, have a dyno run and see where your at then decide the route you go.

Something doesnt sound right with that tbh, 400bhp on 1.0 bar of boost seems way too low boost for that power, got a dyno graph or anything like that?

Assuming the pics you put up are your engine then you wont get there. A semi open deck block wont do 700bhp without shatting itself im afraid :( APS are just bolt on bits and mega expensive for what they are IMO, to get high power figures you need an engine speced from the block upwards, literally every part internal will need to be speced for it, balanced crank, rods, pistons, heads would need to be speced to take it as well valves. As suggested i would decide what tuner you want to use and take advice from them. Just be aware there a re very few tuner out there who regularly build big power cars. Only two i would want to use for something like that would be Scoobyclinic or Enginetuner.

gives us a starting point then :) 700bhp for road use is too much imo, mines been speced up for about 550bhp and that will be daft tbh i suspect 500 will give you what you want. hoe to get there is the question. Just to clarify a few points, It's a road use car will you be doing drag runs? will you be doing track days? to put it into context, this car is mid 600's and while lighter than yours by a way is no use on the road at all, Also be warry of american tuning figures claiming 600+ etc tend to find they arn't anywhere near that in our figures

As said on the next few posts yes mate. 700bhp from a subaru engine is extremely high and is unlikely to last more than 5-10k miles before needing a refresh if it actualy gets to that level. Lets try this a different way What's the most power impreza you've been in?

Afraid your current engine won't do 700bhp and I would expect a bill above 20k to get there.

will affect the speedo reading

rear wiper is a dead give away for an import

comes back as a 1995/96 uk turbo

although totlay different car, this is what a jap vin number looks like vin is just a number, not a 16 digit code

Scoobyclinic up at chesterfield are top notch, mr syvecs himself pat herbron is based there and does alot of their mapping

Uk/european car. Can tell cos jap cars have a 7 digit number for the vin instead of 16 digit cide

Don't skimp on cheap mapping. Easiest way to cost you an engine

fumes are drawn through a fluid that changes colour if exhaust gases are present. Different car so different tank location, but exactly the same test

mine?

pressure test will tell you bob all about HG mate, you need a sniff test done to find that out

yeah rough ball park, shouldnt be an issue on the standard injectors, i ran a vf34 at 340 on v5 uk injectors with head room

doubtfull you'll max the injectors on a vf28 so i wouldn't worry about it. my 28 needs replacing before its mapped, seals are going and now and again it kicks out odd blue smoke.

just to add it varies from car year to car year, also anti lag and launch control are cost options, not that you need em on a road car anyway

Dont think you can get maps zen anymore can you? thought paul had gone to work for ecutek?

yeah was great, for the 4 hours i had a working car on the island,,,,, hahahahahahaha nah really nice place, friendly people and we had some cracking weather. given the changes to the ring now i'd rather go back to the isle of man myself

tends to work out a bit more than an ecutek, but the added benefits it brings are worth the extra imo. Can take a couple of visits to the mapper to sort out cold start (uinless you leave it with em for a couple of days) but once thats sorted then all good.

I use scoobyclinic for all my work based out at chesterfield, Pat Herborn does their ecutek and syvecs mapping and they have an internal guy to do Alcatek.

O don't get me wrong, syvecs is the way to go if you have the extra cash, i would always go syvecs myself which is why i have one, but for a simple decat and map its prob a tad ott at £2k unless you have the spare money lol Alcatek will do the job fine

Givem whjat car you have i'd go with the alcatek option myself, sacks the maf and a very capable ecu.
