croket

i read this whole build on my phone the other night nearly killed my eyes , its a great read and your fab work is awesome too

disapointed to say my car has been havin no issues , leaks no oil strange for a jspec !!!

 

havent been here for a while so i thought id check in with all you VR4 owners and say GDAY

Come on guys get on this and support a club thats all for making the car scene positive. Ill hopefully be there in my VR4

Haha, I wouldn't say I'm too clued on, probably just enough to get myself in trouble trying to learn
The 20g conversion on mine was done by GT pumps as well I believe,(but I didn't get the port job) would be good to see yours.

2 strokes are cool, the ports are slots on opposite sides and you can change the powerband by port shape and overlap, and or a different exhaust expansion chamber. I ported my 60hp Mariner outboard when I rebuilt it, just a tickle though, but it goes like hell! It's a 2 cyl 2 stroke, I think it's from the late 70's and about 648cc or something.

I've tried getting stats on port flow for pressure on 4 strokes, but the info is always based on atmo stuff, with atmo they depend on port velocity which is why bigger ports sometimes lose power, but I figure with forced induction it would be a different story . I'll keep searching and learning I guess. I have 2 4g63 heads atm, one is stage 1 ported, which is just a bit of bowl work, gasket match and sanding the cast lines out.
The second one I've ported out quite a bit larger but still keeping the same overall shape of the port, I will have flow figure for std, vs my ported one in about a month, should be interesting hehehehe.

Here ya go this is my 20g photo not the best its from my phone

I read up a bit when i did my kx 250 two stroke engine and found in most peoples experience it was better not to have high polished but thats on a na twostroke so kinda different i guess. What i read was its good to have a bit of texture to get the air sorta tumbling or whatever.
Im not as clued onto that kinda stuff as you are by the sounds of it hahaha
I will post up the intake on my gt pumps 20g for you to see its nicely ported by them which is a bonus

ill make it to post office friday arvo ill just cover it if its not to much then you can transfer the money to me when ya get it

Hey mate ive got one one but the little flip down parts is missing and its a tad rough from lots of use , if your willing to pay post its yours coz i cant gaurantee its good

my music choice hasnt changed in 20+ years, i will never get sick of this stuff or try anything new cause most the new stuff is just shit

Budgie - metaliica and others done quite a few covers of their brilliant songs, but their versions are the best.
Wishbone Ash
George Thorogood & the Destroyers
Lynyrd skynyrd - Free Bird FTMFW
Van Halen
Hendrix
deep purple
led zep
Queen

No shit budgie i love them got them on vinyl and i havent even hit 30 yet... The only positives of growing up with a rock musician Dad!!!!

I've gone back to recirc as the engine would drop revs ( sometimes stalling ) when coming to stop signs or with the air con on. With the recirc back on it's fine.

Not sure if anyone else has had this problem.

Im pretty sure thats from over fueling from the messed up maf signal,good to see another 4g in my suburb....

recirc for sure , ive got the turbosmart kompact and with decent psi its still gives off a fairly loud noise that i think sounds much nicer then a venting bov

here it is i bought it from my nieghbour now mate , jazz9 on here he is the engine in it was originaly built for a cyborg he owned and has plenty of goodies , ill
post the mods list when i have time its pretty long forged cams and the likes .Its from down here its belonged to 2 of his mates prviously
