Toda uprated 16V springs are cheap enough, i'll get some happening.
Does the GZE run a different spring to a GE, or no?

in stock form, i dont know. but aftermarket 4a 16v springs will with both.

Hi im new to this site iv got a 1984 trueno booter 1.6 4age and ive come across this thread and am in need of advice !

im fitting a 272 deg cam to my 86 and ive got the following parts
cam belt
water pump
steam seals
x2 camshafts
pulleys
gasket kit
head bolts

my cams are going to give me 8.1mm of lift will i need to change my shims ?
i dont want to start the job and become stuck and not have all the parts i need !
also can i install them and leave the timming relatively oem so i can get it rolling roaded / tuned ?

thank you in advance

Changing cams requires the clearances be checked and adjusted. You will need to make adjustments. Measure all shims as they are in position. May get lucky and just swap positions. Look on club4ag I think the thread was written by assasin86

Hi, i'm looking to fit a 'race' cam with around 300 duration to my AE86 big port. It has forged pistons with 9.5 compression. Head is refurb but stock. I am open to changing to under bucket shims and new springs if required.

My question is simple: who should I buy these parts off if i am looking for the best deal? Appreciate company names and even online websites. I know this thread has some great information, but it is also very old at the start. I am based in Adelaide.

Non turbo I guess with those cams ? If so then 300° cams could use a whole lot more compression, probably 11-11.5-1

Agree with above comment. Cams if you want it polite on the street, look for 272 or 264 with +7.9mm lift (toda). Can buy online, would not recommend ebay for cams or gears.

Thanks, yes NA. Will think about how I can increase the comp.

Any suggestions on good online stores for cams? I can't see how to buy toda over their website. Cheers
