kpr Posted September 12, 2008 Author Share Posted September 12, 2008 got some new cams, tuning it at the moment Quote Link to comment Share on other sites More sharing options...
kpr Posted September 20, 2008 Author Share Posted September 20, 2008 have done a half assed tune with the new cams. waiting on bigger injectors as current ones are maxed. but seems to go pretty decent. is gutless till about 5500. then comes on strong and power is on the rise, all the way to the limiter. (8300 at the moment) with a fresh block, more compression and a few other tricks. should go pretty sweet. sold the forged internals for my fwd starlet. and brought these for the 4a instead: 1mm oversize bringing it out to a massive 1627cc. 11.3:1 compression ratio with stock gasket. should be near 12:1 with trd head gasket have a silvertop block getting built at the moment, with the above pistons. arp rod bolts and balance. so should be good for some more revs without flying apart. will give head a tidy up when its swaped onto new block.

kpr Posted November 16, 2008 Author Share Posted November 16, 2008 old engine kinda died a week before it was about to come out. Quote Link to comment Share on other sites More sharing options...
kpr Posted November 16, 2008 Author Share Posted November 16, 2008 so head went to the rebuilders along with block. sweet valve grind shimless buckets trd head gasket, arp studs, toda pistons. head back on. engine dude still has my crank pulley, flywheel and clutch. so thats about it for now Quote Link to comment Share on other sites More sharing options...
kpr Posted December 18, 2008 Author Share Posted December 18, 2008 kinda boring update, new engine has been in awhile and clocked up 1500k's or so. running sweet with a choice lumpy idle. goes a bit better than the old engine. isnt as guttless under 5000rpm thanks to the higher compression. still need to play with the cam timing to get the most out of it. its dialed into the recommended settings from kelfords at the moment.

kpr Posted February 7, 2009 Author Share Posted February 7, 2009 been working on this thing a bit lately. had to make new brake reso relocator, as rubber hoses on old one couldn't handle the brake fluid and melting away and shit. kinda dodgy yeh! so made stainless one, made new megaphone pipe, seems to have gained a bit of power in the lower revs, kinda hard to tell tho. hopefully will have it on the dyno soon, to set cam timing and see which pipe works best. was having problems with it throwing oil out the breather at high revs. put massive breather and catch can setup on it. seems to have worked, as hardly anything comes out the breather now, must have had too much crank case pressure.

kpr Posted February 22, 2009 Author Share Posted February 22, 2009 done a few skids at meremere. best was 14.3, was pretty shit off the line compared to last time Quote Link to comment Share on other sites More sharing options...
kpr Posted February 25, 2009 Author Share Posted February 25, 2009 had it on dyno. couldn't get much more power out of it! my road tune was pretty close. some small gains were made advancing the timing and playing with cam timing. i recon something is holding it back, gonna try some stuff with exhaust and see what happens 1 Quote Link to comment Share on other sites More sharing options...
kpr Posted March 29, 2009 Author Share Posted March 29, 2009 have installed 2.5" exhaust and changed collector slightly. gained heaps of midrange going by ass dyno and afr. but not much at all up top. megaphone must be doing it job now it hasn't got a cork after it. been trying a few diffrent air intake / trumpet setups as well. ended up with this: (isnt quite finished yet.) will get it back on dyno soon hopefully.

kpr Posted May 17, 2009 Author Share Posted May 17, 2009 rebuilt exhaust yet again.. working on "tiny port" at the moment. i have no idea if its going to work or not! half built manifold for tiny ports Quote Link to comment Share on other sites More sharing options...
kpr Posted January 9, 2010 Author Share Posted January 9, 2010 had this thing on the dyno a few times over the last 6 months. blue line is original run, green is with 2.5" exhaust and modified inlet ports and inlet manifold, as above red line is same as above but with different extractors & inlet cam retarded slightly. (made slightly more down low and didnt hold as long up top before changing cam timing) all runs done with the same inlet trumpets and filter etc.. the dyno does fairly low compared to others, if your wondering were all the power is. huge gains below 5500rpm from changing to the 2.5" exhaust system from the 2" one. im 99% sure the gain had nothing to do with the port filling. and was also the cause of the drop in peak power(keep reading). probably done it all wrong who knows. these are the extractors used on the redline run: have gone back to the original stainless ones now. as they make it a bit nicer to drive on the street. had to repair and brace them as they were cracking near the flange. exhaust mounting the ground on every bump, doesn't do much for your stainless headers ! probably going to sell the black ones above. make me an offer if your interested.. had the inlet manifold off just recently to add some vac hoses, turns out the stuff in the ports ^ was about too fall out! was pretty much over it just ripped the head off, bashed it out, biffed head back on. port entrys are a bit golf ball spec now from where i roughed up the port to get the devcon to stick (fail) and inlet mainfold is miss matched. but, now ive had to add a bit more fuel from 6000rpm onwards, no change below. goes the best it ever has now . weird!

kpr Posted March 28, 2010 Author Share Posted March 28, 2010 went to meremere in feb,done a 14.0 at 160km. then i changed some stuff, to surprise a few people (secret weapon) looks the same outside isnt pretty, but cheap and fast build turns out the dude i wanted to beat, crashed his car into a pole, last weekend! stink. went down again anyway. skid 13.1 not bad for having a big boost leak and only running 3-4psi boost.

kpr Posted October 19, 2010 Author Share Posted October 19, 2010 hmm this has been back n/a since about a week after the above post. bit of techo stuff for those that are interested, the green line in this dyno sheet vs the blue line. is basically the difference between my old 2"(blue line) exhaust, and the 2.5"(green line) i changed to. pretty sure the filled ports were partly responsible for the lack of top end on the green line run. ok so i cut off the rear muffler, 2.5 internal dia, but chambered design, it went lean in the midrange. so modified the muffler, internal dia now being near 3.25" and bigger chambers, hoping it will flow near a 3" pipe. results: http://img.photobucket.com/albums/v178/ ... ermods.jpg looking at the afr: green line - new muffer - actually a little leaner than with none brownish line - no muffler. lots loud blue line - old 2.5" muffler thats around an extra 10% fuel in required in midrange. which in theory should be around 10kw. similar amount to when i changed from 2" to 2.5. looks too be some small gains at high rpm also. conclusion: revision is not your friend. and wives tail that you will loose torque with large exhaust. edit: also awaiting another toda part..
