RobPhoboS Posted February 4, 2019 Author Share Posted February 4, 2019 (edited) Well, finally remap day ! I decided to head back to @Jez @ H-Dev as he originally mapped the car for me after I bought it from a forum member here, late 2012 (that's the red plot). Back then I had changed the exhaust (decats back), and a plenum spacer. Wow, the difference now is stark ! Yep, as expected a little loss lower down but once it picks up - VTECH YO ! I guess at this point it's phase 2 for the breathing, and for the next installment it'll be long tubes and potentially some fannying around with the intake manifold. I wanted to at least optimise what the cams can do as the engine is stock. Once the pistons/rods etc are done, I can see where it can go regarding hp/rpm. But even for now the difference really is bigger than what the graph indicates. Edited February 4, 2019 by RobPhoboS 3 Quote Link to comment Share on other sites More sharing options...
350Butcher Posted February 5, 2019 Share Posted February 5, 2019 Seriously good results Rob!! Over 10% increase n/a tuning is great work and as you've said the numbers alone don't do the driving experience justice. Looking forward to following what's next! 1 Quote Link to comment Share on other sites More sharing options...
zelda Posted February 22, 2019 Share Posted February 22, 2019 Great results. When do you expect to do the rest of the internal work? Can you really feel that loss at the bottom? Quote Link to comment Share on other sites More sharing options...

Can you really feel that loss at the bottom? Hey, it's pending finances, and some other things going on at the moment. The next few months I'd like to do the differential, harness bar or 4 point roll cage, long tube headers, get some track days in of course and the usual bits (tyres/pads). So the rest of the engine won't be considered until next winter (or later) unless there's an issue beforehand. You can notice a bit of a difference, so if you need to get a move on you want to drop it down a cog or two but it's soo much stronger at the top now. It really feels quite different to stock in a good way. Quote Link to comment Share on other sites More sharing options...
RobPhoboS Posted April 3, 2019 Author Share Posted April 3, 2019 Some more bits and pieces will be arriving soon ! One of them will require a wrap and a remap (PPE goodness) So, in the name of science and trying to show the process, I will have the car remapped again prior to any engine gubbins being replaced. An order for the guts will come, and I'm just going through the process of what to order for that. Of course I'm doing those things really to help with the oil consumption and to see if it'll help it further up the rev range. I'll probably come back with an approximate list of what I'm intending to do, so once again feel free to comment. The latest addition was Andy's Kaaz 1.5 diff, which is in ! Although probably coming back out so I can fit a different cover and some other little bits Quote Link to comment Share on other sites More sharing options...
RobPhoboS Posted April 5, 2019 Author Share Posted April 5, 2019 I'll be having a chin-wag with 350Butcher at Silverstone, so I'm sure we'll come up with a rough bottom end shopping list. However, if anyone else has some experience on parts, please do chime in. Quote Link to comment Share on other sites More sharing options...
adamc Posted June 19, 2019 Share Posted June 19, 2019 Rob, how do you find the drive now? Does the car feel a lot more responsive than when it was stock? Also did you not have any issues with valve contact as I have read anything over 11.3mm means you may have valve to piston contact? Quote Link to comment Share on other sites More sharing options...

Also did you not have any issues with valve contact as I have read anything over 11.3mm means you may have valve to piston contact? Hey man. Well the car isn't finished in terms of optimising the breathing for the cams yet. If you change cams, you must address intake, and exhaust too (headers specifically) or it's a little bit of a waste. So with that in mind, as it is right now, not much happens until around 3.5k (as you can see from the graph), so you need to bare that in mind when on track and ensure you're in the right gear. A 3.9 FD is on my wishlist which should help a little with acceleration too. Daily driving, less responsive. Track driving, more (but I don't 'daily' the car). If you look at jwt's website you'll see these C8's are designed to work with the DE engine without headwork. But you should always check with the manufacturer on what they recommend, and if it will work with your engine. If you go down the cam route, you need to select the cam very carefully and choose a model for what you intend to use it for. Ex:http://jimwolftechnology.com/wolfpdf/CAM_SPEC_CARD_VQ35_INCL_REVUP.pdf I'd say that cam selection is vital, you kind of build an N/A engine around it. At least that's how I'm seeing it.

TImboj Posted August 17, 2021 Share Posted August 17, 2021 Holy c**p. What the hell got into that bearing?! Really interesting thread, mate. I'm doing exactly the same thing right now with my 03. Has there been any progress? 1 Quote Link to comment Share on other sites More sharing options...
RobPhoboS Posted December 20, 2021 Author Share Posted December 20, 2021 Eeek, apologies didn't spot this ! Yes sir, I rebuilt the whole thing and have done a couple of track days since. I will do a proper thread, promise. However, need to plug in a new (to me) Link ECU/Widebands and get it mapped again, as at low RPM's its not happy and stalls out when coming to a stop/reversing sometimes.
