vipec are just rebadged link ecu's arnt they ? Which are some of the best out there

check your alternator. Could be heating up under the loads and dropping voltage, This with a worn/tired battery could be causing weak spark.. Another one is a bad ground, Over time with the larger that normal loads in track work the battery to chassis, or to block ground is failing, Causing resistance though the heat build-up. I know it sounds weird, But ive had similar things happen.. Current makes heat, Heat can cause resistance. = low voltage

why not get a .86 garret housing fitted? I had a .82 garret exhaust housing fitted to my hx40, with minimal work required..

Try and port/enlarge your oil return, Most stock returns are to small for what the holset require Anyone here running a hx40 yet ? I have one mounted to my l28, Which isnt running yet, would love to see some numbers

oh.. Djz. You havnt posted up here in a while. Im using the same Adaptor Phill is using. Havnt got the car running yet to find out how it performs

Im running a rb30e Flywheel behind my l28et .

fingers crossed that is the cause, will be good to see if it works or not. Ive always had problem in which port to use. I dont understand why they have a top venting port..

definitely interesting the whole throttle body thing, Makes me wounder if im going backwards, since im running a 80mm unit . Would i be better off. adapting a smaller 60mm unit ?

Sorry tony, I think i typed that out incorectly. .. I was merely waiting for a update from Phill...

I think the best thing is.. Where is phill.. Ive been waiting for update for along time

Would be interesting to see what a larger hotside a/r will do actually

Have you tried using a wastegate spring rated closest to the psi you want to run ? That would help spool rates.. (lower threshold)

ooooo!, Has the head change eliminated the surge yet?.. Bring on the dyno tune

http://www.gtr.co.uk/forum/125645-3-5-bar-boost-how.html Here is a interesting thread, that can help you with the flow limitations with compressor wheels. Its a very good read... Of course this doesn't help you with the surge.

use can also use a dull file.. To knock it back flush..

plenty of us here mate

add me to msn messenger mate

Got anymore info pics ect on this r30 your building, id love to see it

I think ill need a 100mm unit

Sure, When i get home. Actually might have some on my photo bucket hang on

Ive got this far.

definitely not a Hr30 until a JDM one if that helps in anyway, Looks like the one i pulled off my 79 l28..

, From what ive found here in NZ only the automatic l28's and the Turbo L20et's
