5e colin Posted June 1, 2016 Share Posted June 1, 2016 speedvision is your best bet on the cheap ish theres a good few sets floating around ireland keep looking the 5efhe cams only work past your 4efe limiter id be looking to minimum get a higher rpm limit Quote Link to post Share on other sites
iano21 Posted June 1, 2016 Author Share Posted June 1, 2016 are the speedvision ones not only for turbo models. . i know same fitment camshaft but would d lobe not be designed different for a turbo than an na?? i done a lot of looking here for fhe cams was not having much luck. and i started with a jap 4e and have just rebuilt the whole thing and also put on throttle bodies and exhaust and have mapable ecu so can work the rev limit . . just thought the cams would finish it off nicely before bringing it to the rolling road to see what she will do!!

iano21 Posted June 1, 2016 Author Share Posted June 1, 2016 but when looking i was not looking for turbo cams Quote Link to post Share on other sites
5e colin Posted June 1, 2016 Share Posted June 1, 2016 there the same lad 4efe and 4efte cams !!!! just looks for 4efte cams for sale Quote Link to post Share on other sites
iano21 Posted June 1, 2016 Author Share Posted June 1, 2016 i know d standard ones are the same but thats cause toyota were too lazy to change the cams between the n/a and turbo but any after market cams are designed for a turbo car i dont think they d degree or lift would suit a n/a but could be wrong ha!!

5e colin Posted June 1, 2016 Share Posted June 1, 2016 (edited) trust me go for it works well Edited June 1, 2016 by 5e colin Quote Link to post Share on other sites
AdamB Posted June 1, 2016 Share Posted June 1, 2016 I don't think the N/A would have enough compression to work turbo cams. Quote Link to post Share on other sites
Trevstar34 Posted June 26, 2016 Share Posted June 26, 2016 (edited) trust me go for it works well I hope your right because I plan to buy some speedvision cams in the near future for my JDM 4efe, although lately I have been thinking that the 8.7mm lift might be too large for a non turbo engine to gain extra power, as air isnt being forced in, the extra gap would cause a loss in air velocity and lead to a loss in power? As for the duration I have no clue Im no engineer so I might be over thinking it, but of course we wouldnt want to waste money on a performance apart that will create a reduction in power Would be good if some one could give some more insight Edited June 26, 2016 by Trevstar34 Quote Link to post Share on other sites
5e colin Posted June 26, 2016 Share Posted June 26, 2016 (edited) if the rpm is going 8k + your going to making some seriouse power those cams from speedvision are extreme so a extreme rpm limit of 9000rpm is advised !!! dont bother on a stock 4efe / and limiter 0f 6.6/7.2 theres just no real power to be had bean there done that the mater of fact is there is no na parts for out 4efe there almost non existent so you have to make deu what you have available Edited June 26, 2016 by 5e colin Quote Link to post Share on other sites
Gainzy Posted June 26, 2016 Share Posted June 26, 2016 Don't forget to upgrade the valve springs by the time you buy decent cams get them fitted amonst other mods you could drop a fte in it seen engine going £500 Quote Link to post Share on other sites
Trevstar34 Posted June 27, 2016 Share Posted June 27, 2016 (edited) the mater of fact is there is no na parts for out 4efe there almost non existent so you have to make deu what you have availableSo either it's either 5efhe cams or nothing really for an NA? Unless I went down the custom route, which is well out of my price range, and I don't like the sound of regrindsDon't forget to upgrade the valve springs by the time you buy decent cams get them fitted amonst other mods you could drop a fte in it seen engine going £500Yes engine is stripped at the moment and some uprated 4efte springs will be going in, along with other mods to compliment it if I get a set of cams, fte will be a project for the future ;) Edited June 27, 2016 by Trevstar34 Quote Link to post Share on other sites
