Ok I own a 2002 WRX Bugeye and would like some more power out of it. At present I have a downpipe back exhaust (original down pipe still in) from WP in aberdeen, JR panel filter, and VTA dump valve. In theory I would be looking at spending £2000 poss a bit more, on the engine. What could that buy? I know very little about re-maps, have heard of APEXi,Tek 3 ect?

What are my options? I know replacing the down pipe for a decatted item is a must but what else?

Help

full decat and remap. thats the cheapest and biggest increase youll ever get.

depends on how small your small budget is...

 

you could probably squeeze a new turbo in there too with your budget....

 

Also do up-pipe, and a remap as a minimum - Tek 3 is probably the best as it keeps existing ECU and just "adjusts" the map for modest power increase. That will spend the first £1k.

After that, it is a case of how you want the car to drive. You could uprate fuel pump and injectors and put a bigger turbo on (do this before your final mapping session). Something like a front entry TD05 would give more power (perhaps 350), but with later spool. Hybrid TD04 from Andy F might give "only" 320bhp, but will spin up as early as your existing turbo. Be aware that if you go much beyond say 330lbft of torque (which the TD05 can achieve), you're also going to severely shorten your clutch and gearbox life - depending on how you drive it, you could break both in a matter of weeks or they could last a few years.

Do a lot of browsing on the drivetrain forum, and learn to use the search facility to find out more!

 

any maybe a set of 2nd hand injectors and a fuel pump to make sure the engine doesnt run out of petrol

 

Neil -we've managed to say the same thing, you just did it in installments!

 

Have done searches on re-mapping but never get the answers I need.

What re-maps are available for my car? Tek3 seems to be the most common.

So..For first stage

Downpipe, uppipe and (standard TD04) re-map for say about 1kish is going to see me in the region of im guessing about 280-290 bhp?

2nd stage?

TD05, fuel pump, new injectors, re-map.

At the end of the day I would like to keep the standard clutch and gearbox as it starts to get into big bucks once they need replacing. However I dont do a lot of miles maybe a maximum of 8-9k a year!

The next question, where is the best place to get this sort of work done. Im up in Aberdeen. I know there is W.P. as thats where I got my exhaust done.

 

Have a good read through the Projects forum

 

ECUTEK (TEK 2/TEK 3) remap is the only one that keeps your existing ECU and just puts new data into it. After that, there are numerous replacement / add-on ECUs, such as APEXI, Link, Motec etc, depends on whether you want the additional cost - if you're only going for the sort of power the gearbox can handle personally I'd stick with a TEK.

With full exhaust and ECUTEK I got 284bhp/272lbft (at power engineering) on my 02 WRX, which is probably above average, but many people get 280ish.

You'd also get a little more from porting headers, suitable Samco etc hoses (the turbo inlet hose gives better spool-up, for example) - but those sort of things don't give huge bhp hikes, just a noticeable improvement in drivability

As for places to get work done, in your location, I'd speak to Andy Forrest who is in East Lothian and generally regarded to be one of the best mappers, does TEKs and APEXI so could advise on those.

 

And another mod that will help a bit is a replacement TMIC, e.g. second hand off an STi for a few hundred, or APS/MRT etc for more like £600.

 

I thought Apexi Ecu was only for Classics only. So you would need Tek 3 remap.

If I had to spend £2k:
Here are some examples on what you could get 2nd hand off Scoobynet and some things new:

Decat Downpipe 2nd hand £140
http://bbs.scoobynet.co.uk/showthrea...light=downpipe
Uprated fuel pump £90 brand new
Equal length Headers 2nd hand £225
http://bbs.scoobynet.co.uk/showthrea...hlight=Headers
TD05 Turbo £350
http://bbs.scoobynet.co.uk/showthrea...highlight=TD05
STi TMIC £280
http://bbs.scoobynet.co.uk/showthrea...highlight=TMIC
Tek 3 Remap around £600
500cc injectors around £400 new

Total £2085

Should be looking at over 350bhp with that lot. But put money aside as your gearbox would be the next thing that would need changing,

 

This was a simular route I took but was let down with some dodgy second hand parts - changing from td04 to vf34 made a huge differnce seemed far more that the original remap and exhaust - but you will find out what lag means

 

Went the same route with my classic apart from the headers, but went with a VF23 Turbo, funny when you change from the TD04 you start to notice the lag on the other turbo. but when the turbo does kick in, you can forgive the lag.

 

I disagree with the power quotes here, they seem very optimistic if all you're going to do is bolt on IMO. How many people have been lucky enough to get a REAL 350bhp from a decat, headers, TMIC, TD05 16g and a TEK3 with just £2k?

Dont know but BOB'5 seem to get a lot of power with bolt on mods on a UK car.

engine mods alone came to £2k, and if you fit them yourself, but if you were going to get someone to fit it all for you then thats more money, but he asked for engine mods on a budget, he might have money set aside for gearbox and brakes, and he already had a backbox, midsection and uppipe.
