the top is to pre charge the spring pressure. so if your spring pressure is 0.8bar if you allow 0.2bar to enter the top it will give you 1 bar of boost pressure if you get me. you will need to pipe in a bleed valve or possibly a electronic boost controller.

Back pressure will be different on all 4 runners, it may flow better but not on a n/a. Plus you get better gains from a equal length 4/2/1 system, or 4/1 system.

I have the alloy pipes from the throttle body to the intercooler. Came off a jperformance intercooler. Didn't fit my 82.

I have both parts if needed.

I think they are 10x1.25.

my friend got pulled by the fuzz a while back. had a vauxhall nova, was lowered and stuff. they pulled him in a riot van. the first thing that was said to my friend was you have a light out. my friend replied so have you. the riot van had a headlamp out, so with that the copper appologised for stopping him and had to return to the station to have the riot van sorted. i got pulled in the almera a while back. after checking everything on the car and my licence etc they found i had a fog light out. me being the keen mechanic i had loads of spare bulbs in the car so i fitted one there and then. funny thing is he wrote out the defect notice (or a 14 day wonder ticket as we call them. they give you one and wonder if you will produce it in 14 days ) but the car was no longer defective. sam 1 rozzers 0!

when replacing rings anyway they all need ''gapping'' to ensure a good seal and give you good compression. if your changing rings and find a piston cracked then obviously a new piston is needed. so basicaslly the same ammount of work is needed to put a forged piston in as there is a standard one. the common thing people do is change the rods too. hence '' forging the engine''. i could go on all day about forging engines etc, but my advice to you is if you want a quick cheap repair put a standard piston back in. if you want to go forged for more peace of mind then it will be costly. you running a td04 at a bar? seems to me that you have gone past the peace of mind stage and could do with it being forged. these engines were designed for a safe around 140bhp. if your adding another 100bhp on top then things are likely to go wrong sooner than later. my opinion obviously.

Sounds like excessive blow by to me which indicates rings or cracked piston. Compression test and a cylinder leakage test are your best bet. Also you can run forged pistons on standard rods. Nothing wrong with that. The pistons crack because they are receiving all the heat and basically a explosion every 2 turns of the crank.

brute force and a big breaker bar
