WindyMiller Posted November 4, 2002 Share Posted November 4, 2002 Well Ladies and Gents, here's the question, What should I do to upgrade my se7en this winter? As a guide the supersport package fitted by Caterham is £1000. Background- It is a 9 month old 1.8 roadsport (basic tune), fitted with, FIA bar, harnesses, leather seats and everything else as bog standard. It is a great little road car and has done about 4500 miles so far. I built it as a novice, so can work out which end of a spanner is which, but I have very little experience with engines! I know someone, I think it's Demon tweeks, does the supersport upgrade ( bits only ) for about £850. I intend spending somewhere in this range. I chatted at the festival and an Emerald ECU seemed a well endorsed alternative. I throw this one to the collective and see what you reckon? Thanks in advance Andy Link to comment Share on other sites More sharing options...
greg Posted November 5, 2002 Share Posted November 5, 2002 NOt owning a K I not the best person to comment, but as noone else has answered I'll chip in with ECU (Emerald) and exhaust seem to be well recommended.

scooby dooby doo Posted November 5, 2002 Share Posted November 5, 2002 Emerald / DVA do a package of emerald ECU and cams similar to supersport cams for that sort of price. And it means the ECU is programmable whereas the SS one isn't. And its can be mapped properly so you'll get much better response and low range than the SS kit. Do you have a std or long primary exhaust 🤔 If the 4 primaries join inside the car then you really need to upgrade this as well - powerspeed will do this for 450 until the end of the month. so (inc VAT) exhaust: 450 emerald: 600 SS like cams: 300 ??? mapping: not much as a few cars in this spec exist already. That will get you to the 140 bhp range (throttle bodies will get you to about 150). HOOPY 500 kg R706KGU Link to comment Share on other sites More sharing options...

robmar Posted November 5, 2002 Share Posted November 5, 2002 but andy's car is only 9 months old so will be an EU3 model Oily are you able to provide the loom connector for this yet 🤔 Rob Link to comment Share on other sites More sharing options...
Colin Grundy Posted November 5, 2002 Share Posted November 5, 2002 Please say yes oily! Link to comment Share on other sites More sharing options...
oilyhands Posted November 5, 2002 Share Posted November 5, 2002 Moves are afoot... the problem at the moment is in acquiring the EU3 loom connectors.. You can always fit the cams first , followed by the ECU when the connector is available. Cheers oily Link to comment Share on other sites More sharing options...
tom7 Posted November 5, 2002 Share Posted November 5, 2002 /HIJACK> Does that mean the standard ECU can cope with upgraded cams? I had always assumed that cams/ECU needed to coma as a package. Will the standard ECU cope with BP285 cams? what sort of increase could you expect froom this? /HIJACK/OFF Tom Link to comment Share on other sites More sharing options...
Colin Grundy Posted November 5, 2002 Share Posted November 5, 2002 Oily As mine is brand new I dont want to splash out on a mems ECU and then another £500 for an Emerald, but I appreciate that your trying to push it along as quick as poss.

Chris Jones Posted November 5, 2002 Share Posted November 5, 2002 The standard mems (that is, the one your already have) can cope quite well with mild cams and porting upto around the 150bhp mark. So some early Piper 270 grind cams and verniers (for ease of fitting and future upgedeability) should perk it upto SS levels for minimal outlay (probably £600 ish fitted). The Emerald can then be fitted later should you want to tune further. Cheers Chris Edited by - Chris Jones on 5 Nov 2002 12:01:52 Link to comment Share on other sites More sharing options...
Colin Grundy Posted November 5, 2002 Share Posted November 5, 2002 Thanks Chris But I havent got an ECU. I bought the engine from Caterham and didnt want to spend an additional £400 for an ECU I was going to replace. Link to comment Share on other sites More sharing options...
Chris Jones Posted November 5, 2002 Share Posted November 5, 2002 Ahh - the penny drops! In that case Emerald everytime! I understand its fairly straight forward to change the EU3 connector to an EU2 with the assistance of Mr wire cutters 😬 Any other ECU will require loom mods, so it kind of makes sense to go with the ECU that has the most available maps! Does your car have the 5AS unit? Cheers Chris Link to comment Share on other sites More sharing options...
WindyMiller Posted November 5, 2002 Author Share Posted November 5, 2002 Interesting! The DVA upgrade to 145+bhp (k02) sounds promising, yes I do have an ECU3, so is this a problem? Hoopy, the exhaust is probably where I'd look next. Just over the grand sounds fair, fitted. Where are DVA based and is it worth going the whole hog and doing the verniers, while it's open?

Alex Birtwisle Posted November 5, 2002 Share Posted November 5, 2002 Andy, I am going for a decent exhaust system first. Then any upgrade to the engine will not suffer from the losses incured by the standard exhaust system. From talking to a few enginey type bods who race K powered cars they reckon the order of priority should be gas in and out efficiently then think about putting more gas in..... i.e. exhaust, ecu, cams, port the head then TB's.

WindyMiller Posted November 5, 2002 Author Share Posted November 5, 2002 Milton Keynes sounds nice and close, umm decisions, decisions! At least this has given me something to mull over. Thanks Colin for putting me straight on who oilyhands really is, guessed it might be something like that. Have a reputation for doing things like this, when I met Hoopy at Arch, struck up a conversation with this guy hanging around, chatted about the Festival and some big wig from arch presenting one of the winners after a race- "Yes that was me!" Foot *arrowright*Mouth 😬 Thanks everyone for the suggestions though Andy Link to comment Share on other sites More sharing options...
