McPikie 0 Posted November 5, 2007 OK, I bought a 1600 GTi. It's got the drums on the rear, 1.9 wheels on make it look like it's got 309 wishbones on etc etc. However, I am not convinced it is a 1600. It pulls like a train through every gear, the engine is pristine and looks like it's been re-conned. Then, to top it off, I stuck to the back on a Phs 1 2.0l 16 Clio 172 yesterday up to 90mph. So, how do I confirm what lump is in it?? Share this post Link to post Share on other sites
simonb 0 Posted November 5, 2007 spacer plate fitted between block and sump = 1.9 yellow injectors = 1.9 oil cooler = 1.9 Hope this helps Share this post Link to post Share on other sites

Chris H 10 Posted November 5, 2007 Quite simple, if there is a10mm thick alloy spacer between the bottom on the engine block and the sump then it should be a 1900, if there is no spacer it should be a 1600 Share this post Link to post Share on other sites
ALEX 98 1 Cars Posted November 5, 2007 The injectors are the best way of telling. If they arn't yellow it's a 1.6. I had a 1.9 engine out of a 405 that didn't have that spacer plate. You can get different depth of sumps. It's more of a stiffener plate than a spacer. Share this post Link to post Share on other sites
steve@cornwall 100 Posted November 5, 2007 How does it pull' is it a clean spread of power - ending at just over 6K, - 1.9 or a noticeable kick at 4K and revs to 7K or just over? 1.6 IMO a good 1.6 trounces an average 1.9! Share this post Link to post Share on other sites
jackherer 543 Posted November 5, 2007 IMO a good 1.6 trounces an average 1.9! Neither will "stick to the back of" a Clio 172 though, if you have an XU 8v and you kept up with a Clio 172 either your engine has had a lot done to it or the Clio driver wasn't trying/can't drive.

GLPoomobile 958 Posted November 5, 2007 Every time anyone asks this question about 1.6/1.9, everybody talks about the sump spacer and injector colours etc. This is all well and good, and can give a quick indication, but it's not gauranteed to give a 100% perfect answer. With the amount of parts that can be chopped and changed by previous owners, replacement engines etc, then this won't give a complete answer. You can run a 1.9 on the wrong injectors (badly) or you could even run it on the wrong injectors complete with matching AFM and ECU etc (i.e. if an owner swapped bottom end and kept everything else OE). Likewise people have mentioned 1.9 engines without sump spacers. So then surely the only way of being confident of the block size is to measure the stroke. I think it was Steve@Cornwall who mentioned this a while ago, about putting a wooden dowel down the spark plug hole and then turning the engine by hand to measure the stroke. I'm I talking a load of giblets as usual or does that make sense? Share this post Link to post Share on other sites
Rob_the_Sparky 9 Posted November 5, 2007 No you are perfectly right, and if someone fits a 1.9 out of a 405 then you may not have a spacer plate (like mine when I first got it, 405 block 205 head). Even the number on the block is no guarantee as like mine you could get a combo of head and block and AFAIK there is no number on the head to trace its origins.

Steve, I wouldn't say it has a noticable "kick", but it does seem to open up alot more at 3.5k. Also, limiter is at circa 6250-6500. It never gets to 7k. I am thinking poossibly 1900 on 1600 box?? Neither will "stick to the back of" a Clio 172 though, if you have an XU 8v and you kept up with a Clio 172 either your engine has had a lot done to it or the Clio driver wasn't trying/can't drive. He can drive Jack, but as we wasnt on a stretch of private road, who knows. Maybe we need to get some sort of "bridge test" to benchmark against. I need to have a good look over the car tonight. I mean, if it was a 1600 and has had a 1900 bottom end/head, but all the 1600 ancilleries andECU, would it still run?? Share this post Link to post Share on other sites

I've just tried a 1.6 ecu with some twin spraying injectors that were fitted to an engine I bought and it was terrible! low rev kangarooing was awful. seems smoother with the injectors, though with the right ecu Edited November 5, 2007 by steve@cornwall Share this post Link to post Share on other sites
simonb 0 Posted November 5, 2007 Sod it - just rip the thing apart then as it appears that there are too many possibilities. I would just look for the obvious things without getting too bogged down. Also - does it drive OK? If so, enjoy it. Share this post Link to post Share on other sites
