CAMotorsport Posted November 18, 2013 Share Posted November 18, 2013 Thats some f****g manifold!! Thats some f****g manifold!! Including the conversion exhaust system & cold air feed Link to comment Share on other sites More sharing options...
Dr H Posted November 19, 2013 Share Posted November 19, 2013 That's still a very impressive figure for a 2.0 NA K20 with no major mods...... Link to comment Share on other sites More sharing options...
CAMotorsport Posted November 19, 2013 Share Posted November 19, 2013 What kind of figures are you all seeing from k20 swaps? Link to comment Share on other sites More sharing options...
DJWilma Posted November 19, 2013 Author Share Posted November 19, 2013 Well the head is off and new head going on tomorrow Looks like the old head had been ported slightly Exhaust manifold was warped, its been skimmed and ready to go back on Oil leak was not what I expected. The cam carrier was leaking, but small amounts. Main problem was it was coming out the dipstick straight onto the exhaust manifold....so will add a couple of breathers. Should be on the rollers on Friday for 400bhp........ Link to comment Share on other sites More sharing options...
Dr H Posted November 20, 2013 Share Posted November 20, 2013 What kind of figures are you all seeing from k20 swaps? 230 is considered a very good figure. I've never heard of a NA K20 making almost 250hp. Was it dynoed on a RR or a hub dyno? Link to comment Share on other sites More sharing options...
CAMotorsport Posted November 20, 2013 Share Posted November 20, 2013 225/230 is achievable at the flywheel on RR with standard k swap conversion parts after a mapping session, add a better cold air feed and an RBC inlet manifold and you are around 248bhp Link to comment Share on other sites More sharing options...
Alex B Posted November 21, 2013 Share Posted November 21, 2013 230 is considered a very good figure. I've never heard of a NA K20 making almost 250hp. Was it dynoed on a RR or a hub dyno? theres a few lads pushing those sort of figures out of N/A K20's on the typeR forums. Link to comment Share on other sites More sharing options...
DJWilma Posted November 22, 2013 Author Share Posted November 22, 2013 Good news is that I was kindly sent me an S2 wishbone to compare with the existing one and it was slightly longer than the one fitted, so seems you the wishbone was an S1 item hence not being able to get negative camberBad news is that the original cams in the engine may not have been the piper 270 ones as they are not stamped by piper on the end. But this will be good news as the cams could be std so happy with the power it was making esp as the head only has a light portCar will go back to Sportomotive to have the Geo corrected properly. Will then drive it for a few weeks and see what its like, then next year take it to one of the know how guys and get it setup how i want it. Secretly hoping the 340R settings will be good enough though :nana Hoping the dipstick oil issue is windage and oil levels but its a worry as its a strange one, but it should be on the rollers this afternoon may even get a couple of power runs and hopeful to go over the 400bhp possibly slightly more if the engine will rev to the 7500rpm i would like :bc Link to comment Share on other sites More sharing options...
DJWilma Posted November 25, 2013 Author Share Posted November 25, 2013 This is what happened today.....low boost is 11psi so spot the problem Looks like the std garrett wastegate is too small and now I am getting more flow through the head it just cant cope so backed out at 6000rpm. Still 360bhp but at 19psi so really have no control ovet boost So ordered an external wastegate and will get this fitted next week. Link to comment Share on other sites More sharing options...
DJWilma Posted November 25, 2013 Author Share Posted November 25, 2013 Yeah just a shame internal wastegate doesnt flow enough but external will control better 44mm tial on order Worse is the fact the tyres wont grip on the dyno, then I saw this plot and realised why Link to comment Share on other sites More sharing options...
DJWilma Posted December 20, 2013 Author Share Posted December 20, 2013 Wastegate is welded in Just hope it all fits, bit "compact" but should be ok Link to comment Share on other sites More sharing options...

jonamacg83 Posted December 29, 2013 Share Posted December 29, 2013 Great job - nice to see something different being done with the engines. Thoroughly enjoyed reading this. I will be interested to see how you get on with this when driving in terms of heat - you can always remove some of the rear grills to get more airflow through the engine bay - this makes a massive difference. Any idea of an 'on the road' date? As an aside, whoever posted that 'if the car is heavier it will have more grip' (or words to that effect) - this is fundamentally untrue, lightweight will always win!

DJWilma Posted December 29, 2013 Author Share Posted December 29, 2013 Heat is my major concern so will be a work in progress. When stationary the ecu switches on a fan in the engine bay to keep the air moving, has larger naca ducts too. Possible side pods but want std look Engine cover maybe first to get modded but will see how it gets on Link to comment Share on other sites More sharing options...
DJWilma Posted January 18, 2014 Author Share Posted January 18, 2014 Been a bit of a struggle to get things fitted External wastegate needed to be plumbed into the water system as it was literally surrounded by exhaust Anyway set point of 1 bar and it did the below, with a nice flat curve Then set point of 1.63 bar and progressive boost control, it did the below, squiggle is wheel spin On monday we will take the cat off and run it at 1.8 bar for a giggle but will run it at 0.9 bar on the road with the cat and just de cat for the track as its all v banded in So all in all quite happy and at 850kgs its 470bhp/tonne Link to comment Share on other sites More sharing options...
