4evaevo Posted May 17, 2011 Share Posted May 17, 2011 I have a 4g63 sigma and l200. the sigma goes way harder than the l200, is the cam in the sigma better? Thanks Quote Link to comment Share on other sites More sharing options...
fuel Posted May 17, 2011 Share Posted May 17, 2011 it should be the same engine, it could be that the L200 engine is more tired than the Sigma engine - that or the L200 weighs more than the Sigma. Depending on the year differences they may have different compression ratios and different spec carburettors etc, but as far as I know the cylinder heads, ports and cams will be the same.

4evaevo Posted May 17, 2011 Author Share Posted May 17, 2011 l200 is a 83 and sigma is a FWD one not sure on year. would a hot cam be the cheapest way to get a bit more power out of the l200? Quote Link to comment Share on other sites More sharing options...
Brock-Lee Posted May 17, 2011 Share Posted May 17, 2011 A hot cam generally wont make hugely noticible power gains by itself, it needs the intake exhaust and fueling mods to go with along with it. Quote Link to comment Share on other sites More sharing options...
fuel Posted May 17, 2011 Share Posted May 17, 2011 oh right, yeah the FWD Sigma 4G63s have a higher compression ratio than the older RWD 4G63s, and if it's an 87 onwards with 'CYCLONE' badging they supposedly have bigger ports and valves too. A cam, port work, bigger valves, higher compression ratio, better carb(s) and extractors would wake the L200 4G63 up. Quote Link to comment Share on other sites More sharing options...
2JZKP Posted May 17, 2011 Share Posted May 17, 2011 some of the power difference will be because the l200 is losing more power with the rwd configuration (drivetrain loss) ie the wheels are closer to the engine in the fwd setup so not as much power is used up trying to turn the wheels, but yes many factors will cause this condition of engine, specs of add on parts etc etc but the basic block and head are the same best thing i ever did to my sigma motor i had in my ex lancer was to put a weber 32/36dgav carb off a mk4/5 cortina went so much better just bolting that (with the adaptor) on and tuning Quote Link to comment Share on other sites More sharing options...
4evaevo Posted May 17, 2011 Author Share Posted May 17, 2011 Yeah its a cyclone. would the cyclone head bolt straght on to the l200? cheers Quote Link to comment Share on other sites More sharing options...
4evaevo Posted May 17, 2011 Author Share Posted May 17, 2011 Are the weber 32/36dgav carbs off the pinto? i have a few of them in the shed. Quote Link to comment Share on other sites More sharing options...
fuel Posted May 17, 2011 Share Posted May 17, 2011 yes the FWD head will fit onto the L200 but the compression ratio difference is in the pistons. You would need to double check that the port and valve sizes are the same between the two, this is just from a few people who have claimed this but I have yet to see for myself. yes the 32/36 DGAV is from the Pinto.

4evaevo Posted May 17, 2011 Author Share Posted May 17, 2011 how much HP does hes engines make standard. Quote Link to comment Share on other sites More sharing options...
fuel Posted May 17, 2011 Share Posted May 17, 2011 around 90-100hp for early models and 100-110hp for later models. twin carb sapporo GSR which is rare to find is approx 120hp. Quote Link to comment Share on other sites More sharing options...
Ogre Posted May 20, 2011 Share Posted May 20, 2011 I bigger cam makes a huge difference even if everything else remains the same.Its easy to get headers for them (i hav a spare set if needed) and the 32/36 dgv carbs are a great upgrade fromn the shit standard ones.I have 2 LA lancers, one has the older 4g63 and the other has the cyclone fwd engine and i have to say that the cyclone engine does seem to go alot better and revs better.Maybe the myth of larger valves is correct although i guess the added compression would be having the same influence.
