camgti 56 Posted May 9, 2018 (edited) Evening all just thought I would write up a quick story. Ive a 98 Xantia Ct in amazing condition and have done a few of the mods to her that others here have done to this motor in their 205! Once again this site has been a huge help! I wanted to open up the engine a little and added a cheap boost controller from ebay. Was rubbish (paid 2$ for it) clearly! Bought a shiny electronic one (turbosmart eboost street) which made a massive difference. Good power from 1900rpm to 4500rpm, almost like a diesel! Exhaust was blowing so had a turbo back system made. Was a fraction larger in bore with fresh mufflers. I didnt want any noise so big mufflers it was and a standard down/sideways exit to keep it stealth. While it was there we fitted a xu10J2 NA cam and gave it a full service. Put it on the dyno to check all was well. 115kw at the wheels so knocking on the door or 200hp and loads of torque. 11ps @ 1900 and 14psi@ 2200-5200 now. Eboost helps hold the boost a little more. Epic bit of gear and Aussie made! Few weeks went by and something didnt sound right. Issue with the cam. Have just ordered a new fresh Turbo Cam from Cat Cams and will have that fitted in a few weeks and am exaited to compare that to the J2 cam. Should make a fraction more due to less overlap etc. Great fun to drive now but god it drinks the fuel! Would be an epic motor in a 205! Thanks for reading!

jackherer 543 Posted May 10, 2018 I did something similar to an XM once, it ended up performing very much like a 3.0 V6. What suspension does your Xantia have? I guess you'd have mentioned if it was an Activa like the 2.0Ts in the UK? Share this post Link to post Share on other sites
petert 586 Posted May 10, 2018 I should add to this by saying we did some serious measuring of the XU10J2 and XU10J2TE cams, with the intention of making a custom turbo cam. Unfortunately no billets were available and thus Cameron had to buy the Catcam offering. Whilst the DKZ cam has been a popular swap, you're prossibly better off using the XU10J2 cam. ie XU10J2TE inlet duration @ 0.050" - 212 max inlet lift - 0.381" exh duration @ 0.050" - 218 max exh lift - 0.432" XU10J2 inlet duration @ 0.050" - 219 max inlet lift - 0.432" exh duration @ 0.050" - 219 max exh lift - 0.432" Share this post Link to post Share on other sites
20five_t 1 1 Cars Posted May 10, 2018 200 bhp isn't bad for boost controller, cam and exhaust. It'll be interesting to see if the Cat Cams turbo cam adds anything with your setup - I've seen a few of posts mention them, but never any back to back tests on the 8v turbo.

camgti 56 Posted May 13, 2018 (edited) Thanks Pete I too am looking forward to the back to back tests. Ive never been able to find evidence just a lot of talk about it! We looked at opening up the exhaust housing of the turbo also (hiflow etc) but the Peugeot specific design of the hairdryer wont allow it. We plan to be putting it on the same dyno tontest results.

Tom Fenton 1,541 Posted May 13, 2018 Wondering if you plan to measure the Catcams turbo cam once you have it? I've toyed with the idea of changing the cam in my 1600T. I use the NA 1600 GTI camshaft in mine, boost threshold is maybe slightly higher than it would be, but I like that it doesn't run out of puff at 5k rpm.

camgti 56 Posted May 13, 2018 No problem Tom. Heres what we know so far Inlet Duration @ 0.1mm - 276° Duration @ 1.0mm - 235° Valve lift - 12.25mm Valve lift @ TDC - 1.85mm Exhaust Duration @ 0.1mm - 274° Duration @ 1.0mm - 237° Valve lift - 11.60mm Valve lift @ TDC - 1.85mm Share this post Link to post Share on other sites
20five_t 1 1 Cars Posted May 15, 2018 (edited) I'm planning to build an 8v turbo and was looking at the catcams turbo cams for it (with xu10j2te block, 1.9 gti head, tt cam, gt2560 turbo etc) - hence the interest. Just wondering, are you going to get it mapped as part of the dyno run when you install it? Edited May 15, 2018 by 20five_t Share this post Link to post Share on other sites
20five_t 1 1 Cars Posted May 15, 2018 sorry, meant to say with turbo technics manifold above (rather than tt cam) Share this post Link to post Share on other sites
camgti 56 Posted May 15, 2018 No mapping yet. We have no people here (in Oz) thst would be able to do it I dont think. As Im staying under (just!) the 1bar boost limit Im hoping the computer will work it out! When changing from Ct Cam to J2 cam the ecu was fine. I would ideally like to have it mapped but I just dont think its going to happen. I dont really want to spend more money on it. If I did I would probably buy the VEMS plug in ecu for a proper tune!

The DKZ cam works, because it does not have so much overlap. Share this post Link to post Share on other sites

Lobe separation 110º When measured on a 106 centreline, it had 0.066" inlet lift @ TDC. Thus less if you set it up at 110 deg. Overlap period measured at 0.010" lift was 96º.

20five_t 1 1 Cars Posted May 16, 2018 1 hour ago, wicked said: Why not just the 2.0v head? Has bigger inlet valves.. Still finalising the plan actually - I have a D6B turbo technics set up out a 205 and also a complete xu10j2te engine so could use a 2.0 head. I was planning just to get the tt engine rebuilt originally, but then thought the xu10 block would be more reliable. I want to use the 1.9 inlet and tt exhaust manifolds so seemed easier to use 1.9 head and other tt bits. Planning to run emerald management and big injectors etc. Share this post Link to post Share on other sites
wicked 103 3 Cars Posted May 16, 2018 I have a tt manifold on my 2.0 head; don't need a 1.9 head for that. The only issue you'll have is the shape of the inlet ports, but that is something an air grinder tool can fix. Use the throtlle sensor/ idle valve / wasted spark coil of the 2.0 and ditch the dizzy of the 1.9. Share this post Link to post Share on other sites
20five_t 1 1 Cars Posted May 16, 2018 I see what you’re saying. The thing is the xu10j2te has a generally poor reputation (in standard configuration & in a 205 anyway) whereas the turbo technics is something sort of original? I just need to think about what bits will work. I’m not planning to sell it, but need to keep in mind what it’ll be worth one day. I think 2.0 bottom, tt other bits, coil pack , emerald & gt2560 will give plenty of power. Share this post Link to post Share on other sites
Henry Yorke 269 3 Cars Posted May 16, 2018 Differences between XU10 inlet manifold and XU9. Throttle body on Xu10 is only 50mm compared to 57mm from memory. You can see where the XU10 inlet marks the XU9 gasket so they are not a perfect fit. Share this post Link to post Share on other sites
20five_t 1 1 Cars Posted May 17, 2018 (edited) Henry, are you running the xu10 inlet on xu9 head? Edited May 17, 2018 by 20five_t Share this post Link to post Share on other sites

FYI: I did some part number checks on service box and found that a lot of XU10J2 have the 0801.P4 cam. This one is also used in the 1.9 D6D engine (Peugeot 405), which has pretty similar specs as the DKZ cam. (0801.N5/0801.N9). According to the Citroen BX haynes, the timing of both cams is identical. From other sources I read that the overlap is 0.5 degrees less on the DKZ cam. Share this post Link to post Share on other sites
petert 586 Posted May 19, 2018 Except the DKZ cam has only 0.405" lift on the exhaust. Share this post Link to post Share on other sites
camgti 56 Posted May 23, 2018 Ok gents. Getting closer. We have also now found someone who can tune the standard ECU. To me this is the most exciting part. Vintage tuning! Im expecting the cam in another 2 weeks and from there we can have it on the Dyno soon after. Has anyone had experience with these types if tunes with this motor? Im not expecting night and day changes, just some fine tuning to make it safe/reliable/powerful! Cam Share this post Link to post Share on other sites
wicked 103 3 Cars Posted May 23, 2018 (edited) Did you order this one? Catcams 4900360 A friend of mine has it with tubular manifold and GT28R. Impressive cam, but had some trouble to get mapped properly at idle/off boost. It has more (not huge) overlap than the DKZ/XU10J2 cam, so I'm curious to see your results with a restrictive manifold/more back pressure.

camgti 56 Posted May 23, 2018 Yes thats the one. Lets hope its not too wild for the ecu or turbo etc. Im not after huge gains just a nice daily motor for the Xantia Barge! Share this post Link to post Share on other sites
