That's interesting to hear rich. However, to keep on topic, it's more about pedal engagement and how the abs behaves when it kicks in rather than over all performance

That I don't know. Seem to recall that the z32 MC is a bigger capacity unit than the 200 one

With tyres and abs, wondering of the extra mechanical grip of being wider at the front almost overwhelms the abs?

Tis always a possibility, but I'm confident it's not at the caliper end. Would like to bottom it out before big brake conversion Tyre wise I'm running Fk453's all round (255/35/18 front 295/30/18 rear) Once of the reasons I brought it up was around the chat i had with JD. He brought it up as something he was looking at resolving on his v8 car. However, knowing alot of the 200 guys change to Z32 master cylinders, may be its down the vac assist side of things?

Guys and Gals Just wanted to see what the general consensus was around brake pedal feel and progression in their zeds To start, im still running stock calipers rebuilt with new pistons, seals, sliders etc, HEL lines, DBA 4000 discs and DS2500 pads all round. Im 99.9% sure my system is air free and im running DOT 5.1 fluid thats less than 12 months old. I do have big brake kit almost ready to go, but im sure this "issue" isnt caliper related. Ok, so as much as im happy with the performance of the stock brakes (although ill freely admit they dont have the out right power that i now feel i need due to my substantial increase in power) in that they VERY rarely fade (even on track), however there are a couple of things that i think could be improved upon compared to new cars (not even sport car specific) Firstly, pedal travel and initial bite of the brake. I have found when changing from the zed to either my work car or the misses company 5 series, newer car have that initial brake bite right at the top of the pedal movement (especially in the 5 series). No when i get on the brakes, the modulation is fine on the zed and comparible to new cars, but personally for me that higher up bite gives me a bit more confidence for late braking/emergency braking situations. I have found however, with almost a slight tap of the pedal (certainly not a "pump") it brings the biting point right up to where I feel it should be. I have discussed this with John Dixon before, and his opinion is that it something to do with the design of the brake master cylinder. While i dont doubt him, im wondering if there are any other contributing factors..... maybe something with the vac assist that could be upgraded etc etc etc....... interested to know your thoughts on this one! Secondly, ABS cut in. I dont know if any of those who have tracked your car have found, but when leaning hard on the brakes (but very progressively) that you can feel the abs pulsate through the pedal, but the ABS isnt actually engaging/disengaging the brakes and you momentarily loose braking force? This is something ive experienced a few times on track, and it can be a bit eye opening to say the least! The only way i seem to be able to get around this is to very quickly (cadence style) disengage and re engage the brakes, and all is well again. As I mentioned in a thread a long long time ago, when taking part in an accident reconstruction with the police (look up 300zx vs merc vito for the thread) that the actuation of the ABS is significantly slower than that of a modern car. Do you think that this odd manner is something to do with either the ridiculously long routing the brake lines make too and from the ABS unit, how the ABS is designed to work, etc etc etc. Oh and something else, have any of you found that when the ABS cut in, it kills the stereo? Id like to know: how many of you experience some of the things ive described above Any further ideas around initial engagement of the brakes in relation to pedal movement, ideas on how to improve it? Any other quirks you have found with your zeds braking system and if you managed to get around them Have any of these quirks been resolved by changing to a Big Brake conversion? etc etc etc Cheers Nick

Nicely done Seems there is a few of us in the 500bhp+ club now!

I can imagine noel cringing as we speak! regardless of the numbers, im sure your happy with it!

:whistling::whistling::smartass:

youll need more than that to get anywhere near 500fwhp! Stock turbos can do high figures as turbo noz has proved, but you need alot of supporting mods. Id add lightened pulleys and flywheel, full 3 inch exhaust, 2.5inch intercooler piping, larger throttle bodies, possibly dual intake, port and polish on the heads to your shopping list

Same turbos as me im having the same problem with late spool up on GT525's. Its like it hits a plateau at 0.5bar then suddenly builds boost up to my target boost of 22psi My personal feeling is that one of the wastegates may not be 100% shut, maybe caused by a weak actuator. Im going to get jimmer to take a look when i have my clutch uprated again How does your boost build with your boost control off? does it hold actuator pressure or does it creep?

Pleased for you Steve More top work Noel !

and 48P heads ;) Im going to say 558 and just over 500 lbs ft torque

Congrats buddy

I'm suprised this has happened tbh. I always thought the zed had a pretty stiff chassis considering its a t top!

awesome!

Cheers Hopefully ill be able to make 2 well bolstered seats out of the 4 that ill have

Yeah, i see what your saying re over all size... Just thinking of overall strength of that bolster. Obviously over time the foam will have lost some of its rigidity and wondering of over laying it with some new foam may stiffen it up as it were

Just out of interest, for those of you who have retrimmed your seats.... Have any of you tried to add additional bolstering to any part of the seat? All im thinking is that while the kidney bolsters are what i would call sufficient, the upper part of the side bolsters which is around the shoulder area doesnt really offer any support. Im wondering if I could maybe add a bit more foam over that top area to make it a bit bulkier Thoughts

Ah ha...... found it..... knew it was somewhere http://www.websure.co.uk/car/300zxretrim.htm

Peeps Is there a guide anywhere on the forum showing how to swap out the bolsters on the front seats, how to re attach them once youve removed etc etc etc As per my other thread, my driver seat base is shagged so Ive managed to source a complete set of Series 4 seats in the same blue cloth as mine. They look in better condition (all be it dirty) but i wont know what the bolsters are like until i sit in them. Ive sussed out the cover removal (though not started yet), its just the foam bolsters im not sure about Ive had a search but cant find anything obvious Thanks

Guess its not needed on ITBs?

Cheeky *******! If anything ive lost weight!

Its scrap mate, there is no way id ever get that completely straight again

Problem found!
