Krister Posted March 12, 2010 Share Posted March 12, 2010 (edited) Cost depends alot if you can shopping around or do some work yourself. We just had this discussion on our local forum. Here's how I would do it: (I used Scott M's list as a base) Custom Single kit: Turbo £800 Ebay manifold £200 Ebay wastegate £150 or Tial £300 Custom downpipe £300 Custom oil lines £100 ECU & Mapping Used AEM EMS £900 Mapping: Learn to do it yourseld, or have it mapped. Free or around £400 or ~450-500hp setup: Chipped OEM Ecu like SARD or Mine's + Apexi S-AFC (~£400 + cheaper mapping) Fuel UK 550's, £120 Fuel pump, Walbro or UK spec Denso, £100-150 Clutch £500-1000 Fitting Do it yourself or have a mate help you. It's really not that hard. New Belts -not needed if regular service has been done New Oil Pump -not needed New Water Pump -not needed if regular service has been done As you can see, it can be done with a budget in mind if you are ready to get your hands greasy. If not, well you might want to pay the £8k then Also this setup is to around 550 crank hp as the limit is the Fuel injectors and pump. For more power, a full fuel system is needed.

Alex Posted March 12, 2010 Share Posted March 12, 2010 We did some testing on Jamie's car with this, not required below 580hp but if you want any more then it's a must. Yeah but to be honest I'd replace the entire system if I was going for 600+ so that would mean it was bypassed as you'd take it out and replace it. For intance I'd use the stock feed line as the return and fit a new #8 feed. Quote Link to comment Share on other sites More sharing options...
AndrewOW Posted March 12, 2010 Share Posted March 12, 2010 This is a good 'idiots' guide to single conversion parts, and it's making it more understandable too. Quote Link to comment Share on other sites More sharing options...

Lee P Posted March 12, 2010 Share Posted March 12, 2010 Not needed though at that level, the stock system will support 650hp with a Bosch pump and injectors. For most people the 600-650hp range is the most they will go in a road car so the bypass line is the way to go. Yeah but to be honest I'd replace the entire system if I was going for 600+ so that would mean it was bypassed as you'd take it out and replace it.

a98pmalcolm Posted March 12, 2010 Author Share Posted March 12, 2010 Yer 600 is a good area for a road car i thought....i got the fuel pulsator bypass done anyway as it was only about £80 fitted! Quote Link to comment Share on other sites More sharing options...
Septic Posted March 14, 2010 Share Posted March 14, 2010 I think I need a triple bypass after reading how much needs to be spent on a big brake kit to handle the requisite power of a single- £2000- £5000?!!! Are you serious??! Quote Link to comment Share on other sites More sharing options...

Are you serious??! No, UK brakes are plenty. Just make sure the pads are decent for top end braking if thats your thing UK Brakes, refurbished with new seals, pins etc etc. Good brake fluid that can take good heat (5.1 is often recommended) and good pads. Job is a good un. Quote Link to comment Share on other sites More sharing options...
Septic Posted March 14, 2010 Share Posted March 14, 2010 Ah thanks Scottt! That's good news! Tbh I couldn't be ar5ed to spend that on brakes straight away. Phew....heart attack averted. Quote Link to comment Share on other sites More sharing options...

Job is a good un. I'd probably stick with stock pads as aftermarket ones are dusty and noisy. They'll be fine on the majority of single setups, although I had Brembos on my last car and the difference is quite noticeable. Quote Link to comment Share on other sites More sharing options...

Scott Posted March 14, 2010 Share Posted March 14, 2010 UK's tend to be a little spongy, not sure why. Brembo's won't have any more stopping power though. I didn't like the stock pads for multiple +100 braking. The CW pads I have are far better, they are as dusty as hell though. Biting at low and high speeds is fantastic with them. If I had the money to spare I would have went with CCX pads, but I don't lol. Quote Link to comment Share on other sites More sharing options...
j_jza80 Posted March 14, 2010 Share Posted March 14, 2010 Brembo's won't have any more stopping power though. My Brembos had quite alot more stopping power than UK brakes. (and I tried quite a few disc/padsetups on my UK spec) Quote Link to comment Share on other sites More sharing options...
j_jza80 Posted March 14, 2010 Share Posted March 14, 2010 One thing that should never be overlooked when planning a conversion like this is tyres. I'd budget another £600+ for a good set of tyres. Quote Link to comment Share on other sites More sharing options...
Scott Posted March 14, 2010 Share Posted March 14, 2010 If you can't lock the wheels up with UK brakes then there is something very very wrong. Think about it from a technical point of view. The pad area is the same, if we are talking 4 pots, and if the pads are good the friction force is the same. Bigger brakes mean more stopping power from high speed, same size brakes make no difference. 4 Pot Brembo's are lighter, that's about it IMO. Oh, I've had brembo's too. Although not on the supra (Evo V) and I would say the difference between the 2 cars stopping is weight. Quote Link to comment Share on other sites More sharing options...
marbleapple Posted March 14, 2010 Share Posted March 14, 2010 As an example if I was planning a single turbo conversion on a completely stock manual Supra with a power goal of around 500-600hp (flywheel), this would be the list of parts I would budget for. Parts would all be quality branded items, no cheap Ebay junk. Turbo Kit Turbo Blanket Front Mounted Intercooler Blow Off Valve and Flange - welding required. Cams - optional Adjustable Cam Gears - optional Exhaust Oil Cooler Radiator - I'd budget for a new one just in case. Fuel Pump - in tank. Fuel Injectors - drop in injectors using stock fuel rail. Clutch Standalone ECU, Harness, Sensors and Mapping Oil Lines, Fittings and Catch Tank Boost Controller Boost Gauge Oil Pressure Gauge Fuel Pressure Gauge AFR Gauge Gauge Pod Spark Plugs Oil Oil Filter So if we were to ask you to source the parts, out of interest (I don't even own a supra at the moment since I sold mine) how much would we be looking at?
