alternative 0 Posted April 3, 2016 I have a question, but first some background!: I have read Damir and Henry Yorke on here maintain the 1.9 CTi gearbox has an excellent combination of ratios. I am wondering if anyone has any other experience of using this box with a D6B engine and GTi final drive? My CTi was fantastic to drive on twisty roads, but I found the FD too low for longer runs. I have rebuilt the DFZ to D6B spec and want to know what to do next... My question is: If I build a one-off box using the GTi FD in the CTi box will it still have the same fun driving characteristics? All help on ratios and comparisons, much appreciated. Done a search but cannot find exact answer. Share this post Link to post Share on other sites
allye 530 3 Cars Posted April 3, 2016 4.063 (1.6 GTI) or 3.688 (1.9 GTI) final drive? Share this post Link to post Share on other sites
alternative 0 Posted April 3, 2016 Not sure as haven't taken them apart. Have two gearboxes with probably both ratios - one in each! Share this post Link to post Share on other sites
allye 530 3 Cars Posted April 3, 2016 Well they are very different! If you are putting a full fat 1.9 GTI engine in the CTI then the 1.9 final will suit you well as you said about cruising revs. Not familiar with CTI ratios compared with standard GTI gear set. If you have the CTI 1-5 ratios to hand and the tyre size you are using stick it into this and it will give you a good idea. http://www.cargister.com/calculator-gear-ratio Share this post Link to post Share on other sites
alternative 0 Posted April 3, 2016 Hi yes, thanks. That's great. Using Speedlines but I don't know how to find the CTi ratios. Saw them once here and can't find them now. The engine is just a rebuilt D6B with 3 angle seats. Its the driving experience I'm interested in, because my 1993 1.9 CTi although only 105hp was fantastic fun using the gears through twisty roads. You felt as if you were going much faster and I'm sure this is down to the CTi ratios which others have talked about. Currently, I may just stick in the GTi box unless I can find out more, but thanks again :D Share this post Link to post Share on other sites
allye 530 3 Cars Posted April 3, 2016 I can't find exact ratios for a CTI, this thread might be a good read though. http://forum.205gtidrivers.com/index.php?showtopic=119080 Share this post Link to post Share on other sites
alternative 0 Posted April 3, 2016 Thanks for that. I'm almost sure that I read the lower ratios in the CTi box are different. Looks as if I'll have to take them apart and have a look, unless I can find more details. Trouble is I'm not sure how the physical ratios affect the driving. The quest goes on (unless I give up)! But thanks again. Share this post Link to post Share on other sites
petert 550 Posted April 4, 2016 I thought CTi was 1st 3.25 2nd - 5th same as GTi CWP 3.94:1 This effectively gives an overall 5th the same as an Mi16. It's a great combo. Share this post Link to post Share on other sites
Anthony 1,000 Posted April 4, 2016 I'm running effectively a 1.9 CTi 'box on mine (1.9 GTi ratios and a 3.9 FD) and it works well IMO, a good compromise on a daily driver. 1 Share this post Link to post Share on other sites
wicked 103 3 Cars Posted January 17, 2018 Can anyone confirm the 1.6 CTI has the same box as 1.9 CTI or does it have the 1.6 GTI box gear ratio's? It's a BE3 unit, but was under the impression that all 1.6 GTI boxes are BE1's. Share this post Link to post Share on other sites
petert 550 Posted January 17, 2018 Not at all. I have a 1.6L GTi box. Share this post Link to post Share on other sites
welshpug 1,622 Posted January 17, 2018 4 hours ago, wicked said: was under the impression that all 1.6 GTI boxes are BE1's. they made the 1.6 gti till 92, they stopped using the BE1 in mid 1989, so that is incorrect. Share this post Link to post Share on other sites
wicked 103 3 Cars Posted January 17, 2018 (edited) Ok, thanks for that. But then the other question: 1.6 CTI box = 1.9 CTI box or 1.6 CTI box = 1.6 GTI box I've been told both, so I don't which one is true. I removed the 1.6 engine from my CTI, so cannot drive with it to check. Edited January 17, 2018 by wicked Share this post Link to post Share on other sites
petert 550 Posted January 17, 2018 I would say the later, as 1.9 CTi has 3.94 cwp. The others have 4.06. Share this post Link to post Share on other sites
Miles 331 1 Cars Posted January 20, 2018 1.6 CTi/GTi are the same, BE1 or 3 makes no differance, 1.9 CTi is odd, Henry Yorke knows, I think they are similar to the 405 SRi Share this post Link to post Share on other sites
wicked 103 3 Cars Posted January 21, 2018 Thanks for the info. So it doesn't make any diff if I fit the be1 1.6gti box that's on the shelf or keep the be3 box of my 1.6 cti ... (with the mi16 conversion) Will be the be3 box.. Share this post Link to post Share on other sites
Henry Yorke 269 3 Cars Posted January 29, 2018 The 1.9 CTI box was the same as Euro Gentry and a German 1.9 Rallye. They were not as short as a 1.6 box yet not as long as the 1.9. Like a 1.6 box with a 1.9 final drive Share this post Link to post Share on other sites
