matt gti78 0 Posted August 20, 2006 Guys, Well I've bought these of ebay today as they seemed a bargain, but knowing me I'm probably wrong. I bought Keihin CVKD38 TB's from a Kawasaki ZX7R to fit these to my 205 GTI 1.9 8v hoping these will work. I know they will need a custom manifold and also need a remappable ECU to change the ingition timing and so on. I'm intending to use the car as a trackday car and also hillclimbing but I'm not spending a huge amounts of money doing this, just the basics really like brakes, suspension,minor engine mods and rollcage and other safety devices. I've done a search for other people buying bike carbs and converting these to fit the engine but just wondered if these TB's I bought will seem to do the job, again I'm not do any major mods to the engine so I'm hoping for about 150bhp or am I lively in a dream world without major modification.

smckeown 1 Posted August 20, 2006 you mention carbs and TBs, which is it ? Share this post Link to post Share on other sites
matt gti78 0 Posted August 20, 2006 There carbs, sorry. Share this post Link to post Share on other sites
Dom9 2 Posted August 22, 2006 If they are carbs, you don't need an ECU as you will lose the injection and you can leave the dizzy in place for the ignition... It's what makes the conversion so cheap... Really you just need a manifold and to reduce the fuel pressure for the csrbs... 38mm bike carbs should work ok up to 150bhp....

jimbean 0 Posted August 22, 2006 is it not a rule of thumb on carbs... 1.6 40mm anything above 45mm surely it is the same for bike carbs... the bike is a 700cc the main jet will need heavy drilling to get the amount of fuel you need for a big motor... i may be wrong but will the heavely enlarged jets nack the driveability?

calvinhorse 870 Posted August 23, 2006 bike carbs flow better than webers so they dont need tobe as big. use the fuel pump of the same bike as you got the carbs off as it will be set for the carbs. the jets are around 10 pounds a set but take abit of trial and error to find the correct ones.
