Gentry_Ba 1 Posted June 12, 2008 (edited) Hi! First, sorry for my bad english- but I'll do my very best I have a 205 Gentry with a 2.0 Turbo engine in it. The car runs very good at max. 1.0bar Boost... (chipped) Now I've heard it's possible to fit another cam to increase power- is that correct or am I wrong? I thought about using a stock cam from a XU9JAZ engine or something else- something cheap to get more power/torque... I think the engine (it's completely stock except the ecu-chip and a mechanical boost controller- I can't remember the english word for "Dampfrad") With this modifications I think it has about 190-200hp and enough torque- but why not increase that by using another cam? I used the forum's search, but I can't find it anymore...? Thank you, Matthias Edited June 12, 2008 by Gentry_Ba Share this post Link to post Share on other sites

Thank you, Matthias Yes the cam you want is from XU9JAZ (DKZ) and the should be plentifull in your country Share this post Link to post Share on other sites
Gentry_Ba 1 Posted June 12, 2008 Hi! Is the DKZ cam ok or are there other cams, which increases the power more? cheers, Matthias Share this post Link to post Share on other sites
whizzer71 0 Posted June 12, 2008 Hi! Is the DKZ cam ok or are there other cams, which increases the power more? cheers, Matthias DKZ is the best option,DFZ (1.9 105bhp low comp) or 2.0ltr 8v (Xantia / 405) are the other options Tris Share this post Link to post Share on other sites
S13Nick 0 Posted June 12, 2008 DKZ which 1.9 engine is that?, mine was rolling road'd at 130bhp standard, could i use that? Share this post Link to post Share on other sites
James_R 3 Posted June 12, 2008 It's the later cat equiped engine low compression, not that many over here Share this post Link to post Share on other sites
Gentry_Ba 1 Posted June 12, 2008 @whizzer: Thank you! Can you tell me if the increase of power is feelable? (oh god my english.... Sorry for that.....) cheers, Matthias Share this post Link to post Share on other sites

Sorry for that.....) cheers, Matthias XU9JAZ from later 1.9 Gti Cat Equipped cars (92>?) running Motronic management,Cant tell you precise power gains as never had a "Before & After" comparison but having driven a car (205 Turbo running 1 bar with std turbo) with and one without, the power delivery/characteristic is completely different . Well worth doing ! Share this post Link to post Share on other sites
carbers205 1 Posted June 13, 2008 I think Rob Turbo ran his with the RFX cam in (2.0 8v) on the understanding that was the best cheap upgrade in the UK. I happen to have a spare one! Andy Share this post Link to post Share on other sites
Jakob 1 Posted June 19, 2008 As long as you are using the standard ex manifold, turbo etc. .... you will have way toooo much backpressure to gain from a more open cam. Just to compare your current flow ...you have 190 - 200hp with 1 bar boost - same engine with "correct" backpressure makes 280-290hp on the same "cold" pressure...(V2 ex. manifold, NA in. manifold, 60RS, NA cam). It is all about flow - and you dont have that at the moment ...you have hot expanded air, and usely lousy ignition to prevent detonation (set by the chip tuner) due to your huge backpressure among others. IMO you spend money on nothing when starting with the cam - dont start by open up your overlab at this stage, you will only run into detonation... In order to flow optimize your engine with cams, you first need to get the basics right and get closer to ratio 1:1 (boost vs. backpressure), rather than 1:4... or what ever is present.
