Hi, we've had our Copen a few months now and looking at upping the power slightly...nothing mental just a bit more poke with bolt on mods and a remap. What's the usual route for tuning these? Are there any tuning specialists to consider in the UK who can remap the ecu? Thanks Crystal
There have been some discussions on re-maps. Not many around for the Copen I believe, well its not a common car. A few have changed their air filter set up and this gives a noticeable difference, if not much power increase but pick up/response is better. This can be quite dear, Copen specific kits for 1.3 don't exist I believe but Adam got one for his turbo. Get a custom exhaust built (stainless), I've read that would be around £400 (350-450) that too would help the responsiveness and add a horse or 2 at the top end. Don't go too big bore though for everyday street driving unless you intend to build a track car. Although the air inlet and exhaust mods are relatively simple, don't expect much extra hp per £. Its not a scooby! But it may make it a more fun and responsive drive.
Thanks for the reply. It's the turbo version and completely standard at the moment. What kind of bhp/torque increase will a remap give on these? The exhaust does need sorting so my GF will probably have to fit a new one, ill get a full turbo back system priced up with Pro Speed in Cardiff. Do you all go for 3" downpipes or 2.5" or just go for cat back systems? Also are there any off the shelf remapped ECU's for these by post or will the car need to ba taken to someone for a live mapping session? When you say air filter set up, is it a simple case of ditching the stock air box and jubilee clipping a cone filter to the inlet or is there a lot of pipe work involved? Pretty new to me the Daihatsu scene coming mainly from Saab, but I did have a Charade Gtti a few years back! My first car!!! If the Copen could get to that performance I think we'll be more than happy Biggest question I guess is how much can the standard internals take before opening the engine up (can they safely take 130/140bhp with bolt on mods?)
are the downpipes the exhaust manifold, part that drops down top of engine to the bottom? I assume. Well there isn't much on the Copen, its mostly the turbo and cat. So best just to think cat back. 3 inchs! its a 659 cc, your gas flow would craw to a halt and get turbo to kick in by 15000 rpm! I just jesting but you can go too big. Big bore is better to race set up where you always top end of the rev. For road you are mostly low to mid so you want to maintain faster gas flow. wide bore kills bottom to mid end torque. Same with your exhaust system. Its more to do with the 1.3 but the turbo is simpler. Remove the front grill, may be bumper. I can't recall what I read, was it 100 hp or 120 hp. But with that you'd probably need some brake upgrade and deffo some wider tyres. 165s not last very long being lit up each time you set off. I'm not sure now much the whole system could take with over 100 hp without beefing up suspension too. 85 hp as in the 1.3 takes you down to 9.5 seconds, assuming similar gearing. So 90 ish might hit 9 seconds. That not enough? If its not get a YRV turbo, under that with no mods!
but I read YRVs roll like the ocean on a rolly day. Roll is not a word in the Copen dictionary. So for the YRV you'd be looking at springs (and shocks?). More space, 4 seater, but she may want the drop top option more, unless twins or triplets are on the horizon!
I just found this JB-DET engine is the same base as used for the heavilly tuned up Storia/Sirion X4 which is 713cc and made around 120bhp. also http://www.amazon.co.uk/Daihatsu-Copen-0-7L-Performance-EVO-TECH/dp/B007KJIEJ8
Just for you interest there is a storia X4 for sale. http://cars.donedeal.co.uk/for-sale/cars/4027144 There is very little in the way of tuning parts for the Copen in the UK. You need to import from Japan. I believe we are yet to find a UK chip tuner for the Copen. However there are a couple in Germany. There are sport ECU's in Japan, but they are not compatible with European Copen's. http://www.dsport-web.com/copen/04_b.html For relatively easy mods I would suggest: * Stainless sports exhaust, cat back. Nothing off the shelf, find your nearest Power flow stockist to custom make one. Or if your loaded import one from Japan. http://www.hks-power.co.jp/en/product_db/muffler/db/11805 * Build your own induction kit. Or import. http://www.hks-power.co.jp/en/product_db/intake/db/5590 http://www.k-takeoff.com/catalog/other/air_cleaner.htm If your going to build one, go with this type: http://www.k-takeoff.com/catalog/other/image/sgenki_l880-l.jpgThere is a direct replacement element from D Sport http://www.dsport-web.com/copen/09_b.html * Fit a decent turbo boost gauge. Plus a fuel cut defender (FCD), & a boost controller. This will allow you to up the boost as bit. If your loaded there are lots of things you could buy from Japan to help. Bigger/better intercooler http://www.dsport-web.com/copen/74.html With steel intercooler pipes http://www.dsport-web.com/copen/62.html Bigger turbo kit with larger injectors http://www.hks-power.co.jp/product/turbo/actuator/dx/index.html If I was going this extreme, I'd put a metal head gasket on. Have a look through my mods thread, there's pictures of the speakers I've fitted plus my induction kit. https://www.copenworld.com/vb3/showthread.php?t=561&highlight=induction&page=4
Thanks for the links there, quite a few bits to look at! That Intercoolers absolutely tiny!! I keep forgetting its only 659cc!! I was looking at the china IC's off eBay but I think they'll be too big. (Pity as I've used a few now on the Saab and they're very well made and coped fine with 470/480bhp) Is there a Japanese>English translator or English web version of the sites? Would love to read the info on there. That Storia looks interesting, never seen one before...200bhp! Must go like a missile! So looking at it she's limited to a cat back system, then new induction kit before shelling out a lot of money for further upgrades? I've got a HKS filter upstairs so if its a simple case of a few silicone/stainless joiners & jubilee clips I might try it myself. Bit gutted about no UK based remap but the German option could be possible. I'll do some more digging, thanks for the help
