what did it run?

redzone · Post by **redzone** » Fri Dec 28, 2007 10:25 am

13.09 @ 108mph with a slipping clutch. then when we did the rerun on the 3rd nov all we got in qualifying was a 13.4 as the pickup in the dissy was playing up and giving us false rpm readings to the ecu's... frustrating! then snapped the lhr driveshaft off behind the spline on the first elimination round on the start line.......

is that the one that you swapped the head on , super low comp ???

what size turbo and boost ??

redzone · Post by **redzone** » Fri Dec 28, 2007 7:12 pm

yep thats the one. cheap as chips KKR430 turbo, 20psi boost. running a fuel only ancient motec computer (1993 model MG22F) and stock starion computer running the original knock retard system..

not a bad effort ,

was the head stock , or ported ?

im interested for some trial and error set ups .

low comp , more torque , GT35 , up the boost say to 28psi

ooooooooooooooooooooohhhhhhhhhhhhhhhhh. knocking on the number 10 ... :D

yeah people are scared of low compression but exhaust housing A/R has WAY more to do with spool rpm than compression ratio. modern turbo engines run a lot of compression because they have a nice pentroof 4 valve cylinder head and they can get away with it. 2 valve heads are never as easy to do that with.

the KKR430 runs a little .58 housing. its all about balancing exh A/R and head flow. that orange thing is on 15 psi by 3000rpm! it is a shitload better to drive down low than a stock starion. yes the 2.4 head is mild ported, nothing dramatic i just took the sharp edges off the port floor and took casting marks off the walls, blended the seats etc. just a basic tidy up. downside to that head is u cant run a metal head gasket as the chamber is oval and runs over the 4G63 firing ring lip

so what exactly was the head off ?

to combat the head gasket issue , is it possible to get a custom made copper type unit ?

im sure apr would make a head stud kit to utilise

yeah just use the arp head stud kit, maybe o-ring it and use a copper head gasket by ridgecrest or something. head is off 2.4L 4G64 efi starwagon/L300 express. 6 bolt type pre 93..
