Luxluc Posted February 14, 2016 Share Posted February 14, 2016 Thanks The direction of the build has been decided by considering what I actually use the car for, and in that context, build on the best aspects of each of my previous Supras. The only other major change I'll consider now will be either a Whifbitz or SRD gearbox swap. Not that there's anything wrong with the tiptronic / Paddleshift system I have, it's just a modern gearbox would better exploit the available power Great plan for the future box upgrade. If I had an auto, that would be on the top of my list. Good luck for tomorrow Quote Link to comment Share on other sites More sharing options...
j_jza80 Posted February 14, 2016 Author Share Posted February 14, 2016 Cheers mate I'm going to bide my time, hopefully a car will end up being broken that I can buy the conversion from. But I am keeping my eye on eBay for both boxes Quote Link to comment Share on other sites More sharing options...

But I am keeping my eye on eBay for both boxes Lee was saying the boxes they use shift quicker than the GTR's :O some serious kit. if I didn't have a 6speed I would be going that route. To be honest its still tempting now. Great build a shame about your mapping though. Look forward to the results Edited February 14, 2016 by Hitbox Junkie (see edit history) Quote Link to comment Share on other sites More sharing options...

Both amazing gearboxes in their own ways. The big downside for me with the SRD setup is how rare and expensive the ISF gearboxes are. Obviously that is outweighed by the much lower initial cost.

j_jza80 Posted February 15, 2016 Author Share Posted February 15, 2016 Sorry guys, still haven't heard myself. I got a message earlier saying the fuel pressure was dropping off, but that's all I know. The single Bosch 044 in the car should be good for circa 600hp, and it's not a very old pump. I'll update the thread as soon as I hear anything. Quote Link to comment Share on other sites More sharing options...
Scott Posted February 15, 2016 Share Posted February 15, 2016 Mine made 600 before running out of fuel on the 044 but I don't think it actually ran out of fuel, I think it was more to do with either the restrictive nature of the stock fuel line or the pre/post 4k pump voltage power. I'm part way through sorting all that out though so that I don't need to worry in future With all that in mind though..... sounds like you might be making some very nice numbers!

That will more than likely be your fuel lines restricting flow at top end - I had an 800 hp rated pump but was restricted to 675/700 by the fuel lines. Hope it gets sorted for you Jay.

With SRD one there hardly any cutting or non at all to the tunnel to fit it also there be more as and when cars start to age or crash, but theres also the older 6speed box too Hopefully your get better updates to your build soon Quote Link to comment Share on other sites More sharing options...

I had issues with my 044 when it was being mapped but only when pushing the limit. I did hit the fuel pressure alarm on the syvecs on the road a few times so I swapped it out for a walbro 485 was perfect after that was using stock fuel lines etc its actually worth just doing it for noise reasons the 485 is much quieter and all Quote Link to comment Share on other sites More sharing options...
j_jza80 Posted February 16, 2016 Author Share Posted February 16, 2016 Sorry for the lack of updates, unfortunately I don't really know any more than I did yesterday. At this rate, I might have an update for you next week Quote Link to comment Share on other sites More sharing options...

Not so bad on a weekend car, but on a daily it does get on the nerves Quote Link to comment Share on other sites More sharing options...
Andrew K Posted February 16, 2016 Share Posted February 16, 2016 I was going to use the Bosch 044 fuel pump for my build but Lee recommended I go with the Walbro 485 and that's what I'm running now on stock fuel lines with no problems.

Rob W Posted February 16, 2016 Share Posted February 16, 2016 I'm surprised you haven't been updated more on this, I know I'd be expecting it. Looking forward to seeing the results when you get them mate, sure it will be a perfect road car setup. Quote Link to comment Share on other sites More sharing options...

j_jza80 Posted February 17, 2016 Author Share Posted February 17, 2016 So, I have an update now. Reports on progress with the car have been delayed as Paul has been off, and Darren and Romain have been run off their feet with other stuff. But Pauls going to keep me in the loop now, which saves me hassling the others for updates The fuel pump is being changed for a walbro one, which will solve the pressure issue, and also be quieter (this will be welcomed, as the Bosch pump is noisy!) The car is suffering from high intake temps. This is seemingly because the Whifbitz SMIC is unable to cope with the demands of my setup, which I was warned about. So for now, Whifbitz are going to fit one of their fmic kits, which Paul has done me a great price on. I'll run this for a little while, and then maybe next winter I'll look into designing an intercooler/chargecooler setup that will allow me to refit the active spoiler. The next issue is that there isn't enough inputs on the Syvecs S6 plus for all the stuff I wanted. So sadly I'm going to have to ditch the cal switch panel, and fuel pressure monitoring. But this way I can still select maps/track through the Toucan, and I will have a basic cruise control setup through a switch. Not quite as ideal as a stalk, but it's only really for the average speed cameras anyway. So the car will either go in for mapping again on either Saturday or Monday.

jcbt Posted February 17, 2016 Share Posted February 17, 2016 Jay The new pump will sort the fuelling problem. To save more work on rectifying fitting a front mount inter cooler could you not fit a Chris Wilson uprated smic which should handle your power requirements - just a thought.

Cheers mate A CW intercooler *may* sort it, but as no doubt the temps are being contributed to by my unwrapped manifold and downpipe, I'd rather go with something that I know will work, and that Whifbitz have in stock.

Wez Posted February 17, 2016 Share Posted February 17, 2016 Do you have any plans to wrap the downpipe and manifold, are you running a turbo blanket? Quote Link to comment Share on other sites More sharing options...
j_jza80 Posted February 17, 2016 Author Share Posted February 17, 2016 Yes, Whifbitz have fitted a turbo blanket I'm not going to wrap the manifold, as from what I've seen it seems to promote cracking. The HKS kit comes with some wrapping for the downpipe, if Whifbitz haven't already done that then I will probably do that at some point. I'll also look to either make a box for the air filter or move it to the bumper duct. And I'll have my fabricator make up some heatshielding when the car goes in to have a flexi fitted just after the downpipe Quote Link to comment Share on other sites More sharing options...
Scott Posted February 17, 2016 Share Posted February 17, 2016 Regarding the inputs, it's possible to use 1 front wheel and one rear wheel for the wheel speed sensing for the TC if that was a help. It saved 2 inputs for me Quote Link to comment Share on other sites More sharing options...
j_jza80 Posted February 17, 2016 Author Share Posted February 17, 2016 Cheers Scott, but they already had to do that the gearbox and then the DBW take up most of the inputs on the S6 plus. Quote Link to comment Share on other sites More sharing options...
