zander205 0 Posted March 10, 2007 what can i do to make my 1.6 faster, any ideas? thought about using the throttle bodies of the toyota 20v and a megasquirt what wanna think? Share this post Link to post Share on other sites
TB_205GTI 1 Posted March 10, 2007 (edited) Sounds like a good idea. Coupled with a XU10 head and a better cam it should be a hoot on a budget. Edited March 10, 2007 by TB_205GTI Share this post Link to post Share on other sites

futura 3 Posted March 11, 2007 Looks like the XU10 was fitted on 605's. http://en.wikipedia.org/wiki/PSA_XU_engine#XU10 Share this post Link to post Share on other sites
brianthemagical 1 Posted March 11, 2007 the xu10 head is fitted on all xu10's. i think the one to go for is the 306xsi head. Share this post Link to post Share on other sites

PsychoSimon 0 Posted March 11, 2007 i think it's because the xsi has the best cam out of the lot Share this post Link to post Share on other sites
pug_ham 242 3 Cars Posted March 12, 2007 i think it's because the xsi has the best cam out of the lotButs its better still to use the standard 205 cam isn't it? http://forum.205gtidrivers.com/index.php?s...c=32356&hl= http://forum.205gtidrivers.com/index.php?s...c=59263&hl= There was a good topic asking this last year, maybe a search will find it.

taffycrook 2 Posted March 17, 2007 I put an engine together with a cam and a XU10 head all machined by QEP a couple of years ago it won a national rally championship and is still going strong. To give you an idea how much more power it had we run out of injector time at the std fuel pressure. Its never been on the rollers but we imagine it has about 130-140 bhp using the std inlet manifold. It would be quite a tool on carbs. Share this post Link to post Share on other sites
taffycrook 2 Posted April 13, 2007 UPDATE!!! Finaly got the car back to do some more work fit carbs and mappable ign. Managed to fit it in for a run on the rollers before the carb swop. 128.5 bhp 110 lbs/ft of torque. About what I expected on the std induction set up. We will see if the carbs open her up a bit more. Mind you the engine is getting a bit tired but will have to do another season funds are low. Share this post Link to post Share on other sites
welshpug 1,627 Posted April 13, 2007 ever thought about an XU5J4 hybrid? Share this post Link to post Share on other sites
Mikey G 3 Posted April 13, 2007 ever thought about an XU5J4 hybrid? I have thought about one of these for a long time. I know of someone who built one for rallying, he mentioned special pistons to get the CR up and thats it, not sure if he used the Mi16 block or not for the oil sprays but the bottom end was just lightened and balanced by all acounts and regularly saw well over 8krpm. I have an Mi engine in bits that needs a new bottom end, may see if i can get hold of a 1.6 crank and have a dabble i think Share this post Link to post Share on other sites
taffycrook 2 Posted April 16, 2007 I was looking into this. It isn't just pistons you need. There is a rally car around localy that has a reported 220bhp from this sort of set up. It isnt easy to achieve and would cost a few bob. Share this post Link to post Share on other sites

If so sounds like the same guy i spoke to at Pembrey. Edited April 16, 2007 by Mikey G Share this post Link to post Share on other sites
welshpug 1,627 Posted April 16, 2007 all you need is the right set of pistons to sort the compression ratio issue, the rest is just like tuning any other Mi16, allbeit a little revvier maybe? Share this post Link to post Share on other sites
taffycrook 2 Posted May 9, 2007 Finally finished this little project or not as it is. On 40's it made 136 bhp and 111 lbs/ft with the std ignition. There was a problem with the mapped ign which prevented full mapping to take place but the results so far are quite good. 137 bhp no more torque but a better spread the curve looks much smoother however the dip around 3500-4250 is a cam issue and in an ideal world would need looking into by swinging the cam timing. I would imagine the gains by finishing the mapping would be very slight, but 87 bhp per litre from a lightly stressed 8v rally engine is not a bad effort for what is bolt on mods. full spec.............. xu10 head cat cam close to group A spec can't remember the part number.
