hi guys, im savin up to replace the head gasket on my n/a zed, im thinking of buying the gasket kit from conceptzperformance along with their n/a oil cooler and while the engines out removing the air con system, water channels that run under the plenum and the clutch bleed nipple, replacing the water hoses at the frount and back of the engine and changing the headers and frount pipes. then i came across the throttle body kit from z1 would it be worth geting this as well just to add a little power? has anyone used them and found them to be a good/bad mod?

i dont know a great deal about tuning the zed so any other info or sugestions about this would be great thanks guys!

Not on an N/A to be honest mate. Throttle bodies on the TT arn't really restrictive until much higher BHP and the gain is minimal to them, to you would be zilch :)

as far as i can recall, one of the main points of air restriction and therfore performace is the throttle bodies with bigger throttle bodies and higher rate injectors a free flowing air filter and good exhaust ( with some back pressure in a NA ) a re masp to suit and the increases are quite dramatic

but i could be wrong :) smithy knows his onions on these cars ........

Thanks guys, think il pass on them. Does the rest of the plan seem ok? I'm kinda thinking if it doesn't have to be on the car I might as well loose it and simplfy the thing as I go. I would like to supercharge it in the future but that's gunna be a long time yet!

with an NA engine the secret to good performance is "get it in get it out"

if you have improved breathing and exhaust and the fuel ratio to match then the outcome will always be more power ...the way your going seems a good approach removing problems before they start ( water ways etc ) ....cooling is important so make sure the rad is up to the job and dont forget if your goingto make it go fast then make it stop first ..brakes are a biggy that many people leave till last and end up in a hedge ..

kep the post going on how you get along will interesting to see a NA project again
