nick_karkie Posted January 27, 2003 Share Posted January 27, 2003 Just looking for a bit of expext input on how to best spend my money. I dont need any exterior or interior styling done. The car has a de-cat exhaust and extensive fuel line work by chris wilson, and some sorta HKS boost guage (excuse me for being ignorant about my own car),, the larger English brake callipers are also present, so I was just looking for some advice on where to go next to improve performance without making the car unreliable. I dont want suspension work done just yet although I am definitely going to do that within the next year. Any opinions are welcome cheers Quote Link to comment Share on other sites More sharing options...
Guest Terry S Posted January 27, 2003 Share Posted January 27, 2003 Hybrids between £1.5 - 2K from Leon ( 01908 367100). S type FMIC about £800. Quote Link to comment Share on other sites More sharing options...
AJI Posted January 27, 2003 Share Posted January 27, 2003 Terry, can you explain how hybrids are better than the stock turbo's? I am thinking of going down a similar line of modification myself. Cheers. Quote Link to comment Share on other sites More sharing options...
Guest Terry S Posted January 27, 2003 Share Posted January 27, 2003 Where to start. They are steel, so stronger than J spec turbo's, all use bigger wheels than stock, so flow more air hence more power, this varies on who you buy from & what stage you buy. They normally use 360 degree bearings & are more boost tolerant if you have the fuel to support it. There will be slightly more lag though, depending on which spec is used. This is a VERY general outline as a few people are selling them now to very different specs, most of whom are unwilling to post the specs so it is impossible to give a definitive answer. I know what Leon does with his, and it is *MUCH* more than some others. A point to anyone wanting hybrids, pay the extra & have a bigger wastegate machined in, who ever is selling them.

nick_karkie Posted January 27, 2003 Author Share Posted January 27, 2003 so what sort of gain are we talking with this upgrade? thanks for the suggestion Quote Link to comment Share on other sites More sharing options...
Guest Terry S Posted January 27, 2003 Share Posted January 27, 2003 Speak to Leon. Ian C recently got approx. 70 bhp more than the others running hybrids & a front mount, but he also has bigger injectors. A lot will depend on the spec of the hybrids. Ian's came over from Japan ( Ian??) so I am pretty sure there are no specs on them. Leon does stage 1 - 4 mild to wild. Quote Link to comment Share on other sites More sharing options...
Ian C Posted January 27, 2003 Share Posted January 27, 2003 Hmmm, I'm not sure if anyone else at that dyno sesh had hybrids? Do you mean 70bhp more than stock-based setups? Anyway, no, I've no idea what 'stage' the hybrids on mine are, there wasn't even talk of 'stages' when I got it Dunno where they came from either, it's a mystery. They seem to work OK, though! Good advice on the enlarged wastegate, though - get it done while they are being hybridised. Oh, and if you need a couple of j-spec turbos to get hybidised, drop me a line -Ian Quote Link to comment Share on other sites More sharing options...
nick_karkie Posted January 27, 2003 Author Share Posted January 27, 2003 So how much does the wild Hybrid upgrade set you back? And can you tell me if there are any other mods I need to make in conjunction with this to compensate for the increase in power (apart from the wastegate- which I will follow your advice and get done). Can you tell me what changing the intercooler pipes from the stock rubber does for the car? cheers guys, you are all great and have a lot of time for us newbies!

Terminator Posted January 27, 2003 Share Posted January 27, 2003 Race Logic Traction Control would be a good idea, help you keep your investment in one piece. Quote Link to comment Share on other sites More sharing options...
nick_karkie Posted January 27, 2003 Author Share Posted January 27, 2003 ha ha, suggesting I'm a bad driver haha...just messing.....but I know what u mean, I have had the rear end slide out a few times even doing 40 mph round a 45 degree turn...prolly coz my tyres are shite stock ones...might have better traction once the bigger 19" pirelli P0 rossos arrive in 3 weeks with my new wheels. how much is Racelogic TC and how does it work better than the stock j-spec slip differential (or are they even the same thing? coz I am useless with car parts and functions) Quote Link to comment Share on other sites More sharing options...

nick_karkie Posted January 27, 2003 Author Share Posted January 27, 2003 Thanks for reminding me Thorin...how long do u think i'll get...I'm not too bothered coz I am a laid back fucker and It'll give my suora a nice rest and give me time to modify it b4 other people see it again Quote Link to comment Share on other sites More sharing options...
Thorin Posted January 27, 2003 Share Posted January 27, 2003 No idea as it seems to vary a lot. Expect a large fine, 6 points, and more than likely a ban of 30 days +. My advice would be to save your £3k, you'll probably need it to pay the fine and nice insurance hike. Quote Link to comment Share on other sites More sharing options...
nick_karkie Posted January 27, 2003 Author Share Posted January 27, 2003 Dont worry Thorin I am getting a nice £18,000 windfall in the next 3 weeks for selling the flat I bought 11 months ago for a nice profit (but I cant spend all of this on my car...I would if I could but my dad would kill me coz I'm supposed to be investing in a new business). Surely the fine wouldnt be over £300, and I will have a traffic cop with me in court to vouch for me so hopefully I'll be lucky Quote Link to comment Share on other sites More sharing options...

Terminator Posted January 27, 2003 Share Posted January 27, 2003 Both stock and RL Traction control rely on sensors sensors located on each wheel hub, both systems use abs sensors Stock TC all settings are fixed, so no adjustment is available for driver style or road conditions. When stock TC senses slip i.e. when one wheel has lost traction and is spinning, it cuts engine power by closing a butterfly in the intake system. This sudden loss of power acts as a brake on the one remaining rear wheel with grip( stock rear diff). In certain conditions this is not only undesirable but possibly dangerous as the rear of the car has lost all grip and the car is at the mercy of the laws of physics and will continue in a line of motion until acted upon by another force. If you are lucky this will be increased friction between the rear wheels and road grip returns, or if you are unlucky any moving or stationary object that happens to be in the path of motion will provide the force. In a UK car the system also acts upon the rear brakes by activation of pulses in the brake cylinders, to slow the wheels down, but as before there will be conditions where this action will exacerbate the situation and lead to total loss of rear grip. When RLTC detects a difference in wheel speeds, it calculates whether this is acceptable ie wheels at different speeds on a bend or roundabout. However if it calculates that the difference in wheel speeds is outside acceptable limits it will induce instant injector cut thereby reducing rear wheel torque, depending upon the severity of the difference in wheels speed the system induces progressively more injector cut. When in a straight line it does not detect differences in speed of wheels on opposite side of the car so allows a higher level of slip between front and back wheels, before inducing injector cut. The result is a very smooth and rapid cut in torque to the rear, but not harsh enough for a breaking effect to be induced. All this happens so fast that inmost instances, the driver will not be aware that it has happened. Even in accelerating conditions the system will not allow the extra power and torque demanded by the drivers right foot until the grip available brings all the wheels back into limits for rotational speed differences. Basically the car will not accelerate until it is safe to do so, no mater what you do with your foot. If you have access to a laptop the only way to tell that the system is working is to watch a trace on a screen. The display clearly shows injector cut and instantaneous and corresponding reductions in driven wheel rotation rates. This whole thing happens so fast, that it is virtually impossible to feel at low levels of system activity. Any traction control system can only control rotational slip, it can not do anything about lateral slip. No system can stop a car from going sideways once grip is lost. Each wheel has a minimum level of grip before it will slip, this is made up of a rotational component and a lateral component. In a straight line the lateral component is negligible, but round corners the lateral component become more significant. RLTC constantly monitors and alters torque to keep rotational slip to a minimum thus allowing more grip on the lateral component, thus enabling the car to corner faster without loss of grip. It does not make you invincible, you can not take the car beyond the grip given by the tires, but it does give you one hell of an edge. It is very reassuring to know you can drive your car hard in relative safety. When I first fitted it I did a 0-100 test in the pouring rain, with the system on, I could control the car with my foot stuffed to the floor. Starting from the same spot, with the system turned off, I lost control and had to take my foot off at some where around 40, had a job to keep the car on the road. I did not try to go any faster in these conditions with stock TC as I was too scared it would put me into a violent spin and stuff me into a ditch. The beauty of the system is you can program it to suit your needs, there are almost 40 variables you can alter to adjust the system to suit your needs. Cost for RLTC is about £600, but there is a group buy under way at the moment so may be less. Quote Link to comment Share on other sites More sharing options...
nick_karkie Posted January 27, 2003 Author Share Posted January 27, 2003 yeah he is going to tell the court that I have driven his son around safely for the past 6 years and that he believes it was a one-off....dont know what that will do...but what do the fuckers in court know. I hardly ever speed, obviously the supra has helped me to break some limits more often than I would have done in my other cars but I generally drive very safely...but they dont care about that...they just after some convictions and some cash Quote Link to comment Share on other sites More sharing options...
nick_karkie Posted January 27, 2003 Author Share Posted January 27, 2003 Thanks Terminator...and congratulations on your 3rd movie which is released soon. That was some detailed stuff...sounds excellent.....so when/if the group buy goes ahead, where can it be fitted and how much will the fitting cost...and how long does it take? Racelogic TC sounds fantastic especially for me cause me supra is very tail-happy Quote Link to comment Share on other sites More sharing options...

nick_karkie Posted January 28, 2003 Author Share Posted January 28, 2003 yeah there is an off switch on my standard j-spec slip-defferential and it is fucking dangerous with it switched off...i thought i'd try it and I had a power slide after 10 secs ha ha Quote Link to comment Share on other sites More sharing options...
