Jynx Posted April 21, 2014 Share Posted April 21, 2014 Hey guys found a local scrappy with a rolla intake and exhaust manifold Just wondering what are the benifits of swapping to these and how are they a staright swap? Cheers Quote Link to post Share on other sites
Rob Scott Posted April 21, 2014 Share Posted April 21, 2014 your probably looking at around 60bhp for the intake and 30bhp for the exhaust, yeah they bolt straight on, but you might need a bit of selotape to hold them on, as selotape is stronger than nuts/bolts.While your at it, get some viper stripes, they give you a good 10bhp.... per stripe!!!

Jynx Posted April 21, 2014 Author Share Posted April 21, 2014 Wow!!! Serious gains will have to stop off at my local staples get some seloptape if all else fails i have gaffa tape ;) Some sound advice there :/ Quote Link to post Share on other sites
Jamie5414 Posted April 21, 2014 Share Posted April 21, 2014 Manifold +5, Ex System +5 maybe more considering make, pipework diameter etc.. Quote Link to post Share on other sites
Jynx Posted April 21, 2014 Author Share Posted April 21, 2014 Thank you not looking for serious power gains more throttle reaponse and torque range really are there any guides on how to fit these i have looked but to no avail? Quote Link to post Share on other sites
Jamie5414 Posted April 21, 2014 Share Posted April 21, 2014 Swap the bits over like in this photo, and just un-bolt your old manifold from the engine and throttle body, and then bolt on the corolla mani back onto the engine and TB. If you can get the Throttle Body to go with the corolla manifold that would be a bonus, so you don't need to make any modification to the throttle cable. Exhaust system is just bolt off and bolt on, get some new exhaust rubbers whilst your at it Quote Link to post Share on other sites
Jynx Posted April 21, 2014 Author Share Posted April 21, 2014 Thanks sir ill have to see if the throttle body is available tooif that makes it easier to fit im guessing new caskets are needed for the exhaust manifold too? Quote Link to post Share on other sites
Jamie5414 Posted April 21, 2014 Share Posted April 21, 2014 No mate they are metal, you can re-use them Quote Link to post Share on other sites
Jynx Posted April 21, 2014 Author Share Posted April 21, 2014 Sound im new to modifying so just looking for advice and simple modifications haha Quote Link to post Share on other sites
dangeestarlet Posted April 21, 2014 Share Posted April 21, 2014 I thought the rolls exhaust mani had to be shortened ? Quote Link to post Share on other sites
richardc9052 Posted April 21, 2014 Share Posted April 21, 2014 the rolla exhaust mani has to be welded on to existing piping or modified to be direct fit Quote Link to post Share on other sites
Jynx Posted April 21, 2014 Author Share Posted April 21, 2014 So its not a direct fit? How much welding or modifying is needed? And is it worth while ie cost effective? Quote Link to post Share on other sites
Jamie5414 Posted April 21, 2014 Share Posted April 21, 2014 Not a direct fit, I wouldn't really say it's cost effective for the gains, unless you are really pushing it to get the most out of a 4efe n/a. Quote Link to post Share on other sites
Jynx Posted April 21, 2014 Author Share Posted April 21, 2014 May just stick with the intake manifold upgrade are there any exhaust manifolds for the na starlet seen few decat ones but they are all glanza ones Quote Link to post Share on other sites
richardc9052 Posted April 21, 2014 Share Posted April 21, 2014 It is worth it not so much for power but it flows a lot better and i found it revved a lot easier. Quote Link to post Share on other sites
Jynx Posted April 21, 2014 Author Share Posted April 21, 2014 This is a plus how much modification is needed for it to fit ? Quote Link to post Share on other sites
richardc9052 Posted April 22, 2014 Share Posted April 22, 2014 Cut the corolla mani on the 2-1 so you have a short single pipe from the Y piece, then cut the pipe on your exhaust to match. tack, remove fully weld and replace Or do the same but add flanges to make it removable but the 4-2-1 corolla mani splits at the 4-2/2-1 part anyway Quote Link to post Share on other sites
