Defcon5 Posted March 25, 2012 Report Share Posted March 25, 2012 Carbs? Why on earth would you put carbs on it? Quote Link to comment Share on other sites More sharing options...
jabbles21 Posted March 25, 2012 Report Share Posted March 25, 2012 Carbs? Why on earth would you put carbs on it?And no. Just no, realistically, after the 125 out of the factory engine has had some use. A rr-ed 130, optimistically 140. Quote Link to comment Share on other sites More sharing options...
James827 Posted March 25, 2012 Report Share Posted March 25, 2012 And no. Just no, realistically, after the 125 out of the factory engine has had some use. A rr-ed 130, optimistically 140.What he said. much more work to get the 180hp figure. Not worth it for the price and power gains. might be more responsive to drive mind..

chippi218 Posted March 25, 2012 Author Report Share Posted March 25, 2012 instead of carbs what would you do? Quote Link to comment Share on other sites More sharing options...
James827 Posted March 25, 2012 Report Share Posted March 25, 2012 Personally if i had a GTI, id leave the engine be. Manufactures spend hundreds of thousands of pounds developing engines and components for a reason. if it aint broke, Don't fix it! Quote Link to comment Share on other sites More sharing options...
nic78 Posted March 26, 2012 Report Share Posted March 26, 2012 instead of carbswhat would you do?Do you mean throttle bodies? Quote Link to comment Share on other sites More sharing options...
CasperGTI Posted March 26, 2012 Report Share Posted March 26, 2012 Itb's and cams with all the rest of the mods will see you about 165.140 is achievable with a exhaust and induction system coupled to a remap.John Quote Link to comment Share on other sites More sharing options...
scotty_82 Posted March 26, 2012 Report Share Posted March 26, 2012 Would carbs even work on a gti engine, wouldn't you need the ecu for the Vvt or is It a mechanical switch over Quote Link to comment Share on other sites More sharing options...
chippi218 Posted March 26, 2012 Author Report Share Posted March 26, 2012 Haa ye i was just thinking. The gti is injection i think. Im not the best person on engines : pThanks casper:) Quote Link to comment Share on other sites More sharing options...
Thissy Posted March 26, 2012 Report Share Posted March 26, 2012 As casper said a decent manifold & cat-back coupled with an induction and remap are the obvious and most cost effective modifications. 145bhp can be achieved with those alone. I know 'foxy' achieved those figures.. I think with cams you could push 155bhp but you lose drivability and fuel economy goes out of the window. Thats without mentioning how much of a ball ache it would be to fit cams to the GTi with the unusual head design.. I have no experience of ITB's but from what i can gather you lose power (in comparison to a standard engine) up until about 4.5k?Mike Quote Link to comment Share on other sites More sharing options...
chippi218 Posted March 26, 2012 Author Report Share Posted March 26, 2012 ahh cheers.much appreciated Quote Link to comment Share on other sites More sharing options...
CasperGTI Posted March 28, 2012 Report Share Posted March 28, 2012 Itb's are where things become difficult, especially with the Gti. You would need to convert to cable throttle and then run a standalone Ecu.There is a Gti running cams on here, we're the first set made for the Gti engine by catcams, there were a few issues I'm told, just waiting for results from a remap now Quote Link to comment Share on other sites More sharing options...
Hawkesybaby Posted April 3, 2012 Report Share Posted April 3, 2012 Personally if i had a GTI, id leave the engine be. Manufactures spend hundreds of thousands of pounds developing engines and components for a reason. if it aint broke, Don't fix it!Personally I really don't agree with this...Your telling me that vw could only get 125bhp from a gti engine and that's where they wanted to leave it? And if the above were true then why is there modifications available to better improve the performance of said engine, infact any engine? Even something as simple as a remap improves the performances of engine whether NA or turbo'd why do the manufacturers not have this sort of map when it come out of the factory?I'm not moaning btw just my opinion Quote Link to comment Share on other sites More sharing options...

E.g. PD130/150. Astra CDTI 150/888.Thus, justifying tuning an engine. Quote Link to comment Share on other sites More sharing options...

Defcon5 Posted April 3, 2012 Report Share Posted April 3, 2012 Manufacturers have to factor in extended reliability, not to mention the fact the car will be sold all over the world - including climates much hotter/colder than our own. Any increase in power will result in a decrease in engine longevityAs with everything, its a compromise. Quote Link to comment Share on other sites More sharing options...
