L33 Posted January 11, 2009 Share Posted January 11, 2009 http://www.mkivsupra.net/vbb/showthread.php?t=171382 not sure which cams will be right for my build so wondered if any one could help. having a boostlogic auto box if that makes any difference and some wiseco forged pistons. hear a lot of people use 264? but not sure if thats right for what i want, or how do you know what suits bit different but i had cams in a old 106 gti years ago and it was always stalling and very lumpy, cudnt let it idle with out haveing my foot slightly on the acc. dont want to be in that situation again as its unusable! cheers Quote Link to comment Share on other sites More sharing options...
JamieP Posted January 11, 2009 Share Posted January 11, 2009 What power do you want? if 550bhp or less then stay with stock cams would be my advice. Quote Link to comment Share on other sites More sharing options...
L33 Posted January 11, 2009 Author Share Posted January 11, 2009 im targeting 600, thats why im putting forged pistons in Quote Link to comment Share on other sites More sharing options...

JamieP Posted January 11, 2009 Share Posted January 11, 2009 Id go with Jun 256/256. Quote Link to comment Share on other sites More sharing options...
L33 Posted January 11, 2009 Author Share Posted January 11, 2009 jamie, what was your gt4088 running bhp? you had 264 cams? to be honest not really sure what power i wil have but i will be happy to have it back, just been told with a spec like i have it should see 600bhp. not sure how far from the truth that is? but while the engine is being rebuilt i thought i would but forged pistons and cams in to be able to take the power what ever i get Quote Link to comment Share on other sites More sharing options...
JamieP Posted January 11, 2009 Share Posted January 11, 2009 Im on stock cams at the min but have the Jun 256/256 ready to go in soon. My old red car was on GT4088 with 264/264 hks cams and the best power it made was 615bhp on Dans dyno. Quote Link to comment Share on other sites More sharing options...

My old red car was on GT4088 with 264/264 hks cams and the best power it made was 615bhp on Dans dyno. so it might be best to use the same cams you did on your gt4088 as i have the same turbo? or the 256 better? whats the difference between them? drive wise and performance?

JamieP Posted January 11, 2009 Share Posted January 11, 2009 The bigger the cam the more lag (but will make more power) go on Ryans dyno page and compare my power curve to IanC's, both have same turbo but he has cams and lots of lag compared to mine. For 600bhp id go 256/256 but do some more research and make your own mind up. Quote Link to comment Share on other sites More sharing options...

lui Posted January 11, 2009 Share Posted January 11, 2009 (edited) HKS 264's in & out on mine & no lag at all Edited January 11, 2009 by lui (see edit history) Quote Link to comment Share on other sites More sharing options...

L33 Posted January 11, 2009 Author Share Posted January 11, 2009 o hello lui! turbos went this morn how lumpy is your car with the 264s? or is it a smooth drive>? a lot of people do seem to run the 264s, not heard of the 254 before Quote Link to comment Share on other sites More sharing options...
DARETT Posted January 11, 2009 Share Posted January 11, 2009 As said 264's will have better top end in comparison to the 256, however the 256' will be better for low down torque. Idle with 264's should be dot on, it's not until you go to 280's when idle speeds are noticeably different Quote Link to comment Share on other sites More sharing options...
L33 Posted January 11, 2009 Author Share Posted January 11, 2009 which would be better for 1/4 mile? the torque would be good for off the line but then you need top end? Quote Link to comment Share on other sites More sharing options...
L33 Posted January 11, 2009 Author Share Posted January 11, 2009 which make ect would be best to get and who from? trader on here or some where whifbitz? Quote Link to comment Share on other sites More sharing options...
Wez Posted January 11, 2009 Share Posted January 11, 2009 Id go with Jun 256/256. Good advice I gained 50hp with HKS 264/264 but it moved my power curve over approx 500 to 1000rpm. If I was doing cams again I would seriously consider the JUN 256/256 setup, only issue is no one has tested it yet. Quote Link to comment Share on other sites More sharing options...
DARETT Posted January 12, 2009 Share Posted January 12, 2009 IF it's going to be drag based then it would probably be better for the 264's for the top end. Give Whifbitz a call, they stock near enough everything and the HKS cams as well. Pricing is reasonable as well Quote Link to comment Share on other sites More sharing options...
Marty Posted January 12, 2009 Share Posted January 12, 2009 I have 264's on mine and they are very good. My car makes really good power on relatively low boost. Can't comment on any other durations though as i have not driven any other supra's running cam's. Quote Link to comment Share on other sites More sharing options...

Marty Posted January 12, 2009 Share Posted January 12, 2009 That's a good result you have with your T67, 570 at 1.1 When do you see full boost?.... Its actually 565bhp but that's close enough to 570bhp for me its on full boost approx 4000rpm, but my turbo exhaust blades are damaged at the ends so i'm sure that affects the spool somewhat. The cam's make a huge difference top end though, it pull's extremely well past 5k. Going to get the turbo refurbed if possible and then get a re-map up to 1.4-1.6 and see what numbers i can come out with Quote Link to comment Share on other sites More sharing options...

dandan Posted January 12, 2009 Share Posted January 12, 2009 Does anybody know what the lift is on a JUN 264 exhaust and also if it is the same (actual) duration as an HKS 264 exhaust? Quote Link to comment Share on other sites More sharing options...
