well, apon some measuring and closer inspection last night and at the engine shop this morning. the bores are fine! the engine was out of a low km TS magna before the 20 year old pistons were thrown in the pistons are showing no signs of lean burning or det. BUT they have a LOT of wear in the ring g...

stock pistons are capable of 200+kw
but if going for a budget rebuild i would get some ACL duralites, theyre not expensive (i got some on ebay for $60 new)

CP and Wiseco will also do forged, and i think RPW sells arias forged pistons. but they are all around 1k a set

yeah thats kinda what i was thinking. but it wasnt a choice i had.
i guess itll be better than a stock cam for though.

aiming at 400hp, and max of around 7k rpm what would be a guide to look for?
i might give the guy who used to be at bezerkely a call in the coming future if this doesnt work well.

Sorry mate but if it was tuned right on the right fuel for that boost level it would still be alive the problems you have there are not component failure they are tuning issues. cheers Mic well it was perfect for atleast 8000km with the tune unchanged, only its last 2 weeks it felt like it progress...

i thought id post up here what i think to be the limit of stock engine components, or atleast it was in my case to start it was a dead stock astron2 from the wrecker i removed the astron2 flat tops and fitted some dished pistons that i got from a bomb at U-pull it i bought the cheapest rings i could...

ill stick with the solid rockers after reading that.

im looking at a pile of cams, heads and rockers. ive got a crow 701 grind to go into the new motor, heavy springs, ported head, bla bla bla. i am going to use early astron Solid lifters, but was wondering what the effect of using the roller rockers if i converted them to adjustables with some machin...

Hello people this may have been asked before but im wanting to put a disc brake rear end in a GH Sigma for the speedway.. Can you please help me out what would be the best?

thats just what im after, cheers

ill have a go at adapting a subaru rack, theyre fairly short and ive got one spare

i just hooked the tacho to the coil -ve directly, shouldn't matter what kind of coil your running

has anyone done a rack and pinion conversion on a sigma?

all the steering components are shagged on my car and im interested in the s13 coilover conversion aswell
so i thought about using the steering rack to suit too, could it be placed on custom brackets where the steering rail currently goes?

new engine with new rings will leave the oil looking mettalic till the firct change.

take the oil to a mechanic if unsure, but if youve already dropped the oil once after over 50kms then i would be a little cautious

havent had an alignment yet and dont know how the tyre wear will go. You need to readjust the toe when you do it because it changes the toe a little. Toe is really the only thing that is adjustable on these cars, so I do it myself by taping a couple sticks to the tires and measuring between the end...

good to meet new faces and catch up with others.

i had fun making the old girl slowdown and turn at the same time too much brake bias can be fun

Same Here

i did the same on my GJ, it did make a noticeable difference.

havent had an alignment yet and dont know how the tyre wear will go.
has anyone been running reasonably wide tyres with this done... does it dramatically wear the tyres unevenly?

lol, i was expecting a few ppl to put their 300rwhp info up but really more interested in stock or minimal mod information to get a bit of a comparison on basic mods ie, stock 2.6 carby -> stock 2.6 EFI and maybe other things like mild cam, ect. noone is going to post up 300hp na anything. and its ...

From looking at ebay, it looks like some of the ECUs are 2 plug where others are 3 plug.

In SA, all I have to do is go to the Motor Registery, fill in ...
