Are you going to check the valve lash whilst in there? To all those here with doubts about doing this DIY I can understand where you are coming from - there is quite a mental barrier in the way of doing some open heart surgery on the engine. Before doing mine the most mechanical experience I had was changing discs and pads, oil etc. but I pride myself in having a decent amount of common sense. I managed to get though it ok so I imagine that many others, more mechanically adept with some common sense of their own can do the same. Just be clean and careful not to ding anything. It does take some stomach though so fair play for taking the plunge! Will all be worth it when it fires up after doing the work yourself - smoke free and all!

Well done Bailey! I bet you are well chuffed with the result and relieved that all you hard work has paid off. I have exactly the same issue with mine missfiring - she behaved up to 1.5bar on the dyno to get the result I had but I have been running mine at 1.2bar since and I still have yet to get used to it. I am thinking of getting some superspark coil packs to cure it for good. Will be looking forward to a passenger ride if poss to compare!

Be careful people, I only asked Blackie to see his pet python and look what it got me! Any excuse eh? Was Bailey still looking for his sidelights in the last pic?

Sorry for the late reply. Blackie's rohypnol only just worn off... Cheers to Al and Karolina for having us and supplying me with some of the best chips ever! The bacon sarnies were a life saver too for the horrible drive back. I do think you should hardcore it outside with us propper campers next time Sorry to Buster for the flying kneecap to the face! Ill pace myself until after the trampoline wrestling next time! Nice to meet some new faces too, hope to see you all again later wherever the next meet takes us! I'm going to go back to sleep on my keyboard now!

I don't think Jim's slack.... well maybe a little overused. I'll still be in attendance - dunno if I'll bring the supra if it is raining though - it's completely useless in the wet now Fingers crossed for sun!

The way I understand it is that fuel and ignition are mapped against engine load and rpm (a 3 dimensional table). The mapper needs to set the amount of fuel and ignition timing at every possible rpm and load. Therefore if the car cannot make or fuel a certain boost level at the time of mapping then the mapper can't enter the appropriate values and test them for det etc. If you want to see for yourself then I'd go to AEM forums and download AEMPro. It comes with a supra base map and you can look at the fueling table to see the 3d table and see how the ecu can work out what fueling is needed for any given rpm and load (boost/MAP) that the mapper programmed into it. Well that killed some time whilst waiting for an MOT....

Nice work. I wish one of my friends would become an MOT tester! Got mine on Tuesday and I have to fit 2nd cat It passed last year with it.... just!

Sorry to here this dude Fingers crossed that it's a quick and easy fix but at least it's in good hands with Lee.

Yeah that ^^ I was going to suggest Tony's guide as I used it to fit my 264's.

Looks like it's entering the cabin where the loom goes through from here. Got a boost gauge or an electronic boost controller hooked up?

Got back from holiday and a 3" Whifbitz Twin Box was waiting for me - much more sociable than the Nur Spec - until the wastegate cracks open anyway! Sound Demo: 3wJP9o-qq1M

Yeah thats the one - it cost a fair bit from Merlin but might be due to it being branded. I need some more to make an airbox out of - do you mind me asking roughly how much it cost from Lee P? Wish I had a black engine bay

Does look nice Where did you get you heat shielding in the end? Merlin Motorsport?

It's a shame that so many in the list are missing their dyno plots (mainly the manual ones). I know power as a raw figure isn't that useful and dynos not consistent but seeing the torque and power curves along with the choice of turbo, cams, ecu & boost used to achieve it really helps give you an idea of what combination works well when choosing your own setup for your particular goals. Without the plots, the results don't tell you nearly as much C'mon everyone! Get your dyno plots uploaded!!

More than likely! Got the Suprq ready for the summer and will not be missing a chance to go for a drive with everybody. Yours will be done and dusted too by then?

The boost controller should get it's reference from the manifold - it is the pressure there that it is trying to control after all EDIT: As per Si's post, I suspect that either would work so I'd go with whatever uses the least pipe possible

I thought it be best to keep mine short too but my compressor housing has no barb on it for fitting it there so I had no choice but to route it all the way from the inlet manifold. Ryan had steady control over my boost by the looks of my dyno chart so it seems ok like this As for how you've done it Andy it looks right and as you are not using the ECU to control boost then yes your boost controller will also be needing to read the current manifold pressure so you are right on all counts I'd say! Is the v pro not capable of controlling boost at all? Just wondered why you didn't go with ECU control? With a separate controller you can have instant manual control over the boost but I find just having a high/low setting is good enough for me

I think I know what you mean Andy - When plumbing in a boost controller to the external wastegate you need to tee off one of the boost lines. I used this diagram that Kev.O posted in another thread to do this:

As above mate, what are you having issue with? Do you just need to know what all your vacuum/boost (same thing) sources will be used for now? I think the ones I have from memory are PAS idle up, MAP sensor, FPR, boost gauge and external wastegate. Oh and a breather hose connected to the PCV on the inlet cam cover. I just connected all these up the what was available on the intake plenum with vacuum hosing (with T-pieces where appropriate). anything left I've blocked off.

Don't forget to get a video of the big moment! Bet you're getting excited now

Fingers crossed for you mate and hope Matt finds the problem for you and that this was just a case of assuming the worst had happened to the box!

Cheers Jamie, I'm surprised at the power! I wasn't expecting to see these sort of numbers without a fair bit more boost. I'm still adjusting to the power at the moment but luckily it's quite progressive for a single so quite forgiving of my lack of skills! Yup, 1.5bar mate. I was quite surprised at the size of the gap between yours and mine to be honest as our builds are about as similar as it gets. The billet wheel must be moving a fair bit more air but it would be interesting to see yours on these cams to see what proportion of power is the turbo or the cams. I am slightly down on torque from you as well. Thanks guys, certainly worth doing it yourself although I can't take all the credit. With Paul's turbo kit it really is just nuts, bolts and common sense for the most part - quality piece of kit! Cheers Andy - won't be long until yours is done - you're gonna love it! I am dude cheers! Last time I didn't quite get what I wanted so aimed lower this time and got higher That was an experience, let me tell you - clutching many mugs of coffee just to keep my finger mobile! That was at the beginning of the build when I was dedicated - by the 6th month my motivation was dropping slightly so I'm glad I did that first! Was unbearable mate! Haven't felt like that since doing my driving test or Uni exams - it was me and my pride being tested as much as the car! Thanks for the kind words people! Finished this build off nicely for me!

Thanks all! I'm real glad I did the work myself - I learned a LOT! It's all less complicated than it seems if you have some common sense and basic interest in how stuff works. Wouldn't have minded some air tools and a warm garage to work in though! I'm sure that anyone else with more experience than me and the right tools could pull this off much quicker but actually the majority of the time was spent waiting for parts! I've got the billet 62 Rob (batmowheel) and it seems like it is making a difference over the cast version. My closest comparison is ADD but he doesn't have the cams so not sure how much more power is actually coming from my turbo or just the cams. I am 6 speed yes, used to be Auto but AFR converted me about a year and half ago. Certainly glad I did as once I'd experienced the power I knew it would be hard to turn the power back down to save the gearbox.

Was last November when I decided to take the car off the road and since then I have been watched from my neighbours windows as I have changed stem seals in the snow, gone through a set of injectors and a turbo and endured comments like "still at it then?!" for the last 6 months on my driveway but it all ended this week. Met up with Ryan first thing in the morning at SRR and he got straight to work. After some initial setup the car was ready to see some boost and I was ready to have a heart attack as I was practically a nervous wreck, worried about all my DIY efforts on the driveway! Felt like it was me being tested and not just the car! Turns out I had little to be worried about as the numbers started churning out of the dyno. 435...497... 530.. I thought, bingo! I was expecting around 550 from a 62mm turbo so was happy already but next thing I know, Ryan is telling me these figures are at the wheels with the final figure actually being 624.7BHP @ the flywheel with ~520ftlb torque I was shocked at completely passing the 600 mark, the reality of which was soon highlighted as Ryan could not safely map it any higher as the 725cc ID injectors were approaching their safe limits. I hadn't prepared for the need for this much fuel but luckily I did aim a little higher! Now I have had a chance to drive the car I can't say enough good things about the way it drives - it's simply awesome and put's a massive grin on my face every time I put my foot down on the go pedal! It's everything I expected from a single after having a couple of single supra passenger rides in the past and makes all the time, money and effort seem worth it. The turbo spools up pretty much where the 2nd turbo on the stock TT setup does so apart from the massive hike in power, it feels like I'm partially used to the way it drives already. Once spooled though it is a different animal altogether and simply pulls and pulls and pulls! The combination of this batmowheel turbo and cams seems to work well and makes the car feel so 'unrestrictive' up to the redline. Sorry to blabber on though! I think I'll stop here and just thank Ryan for his awesome work, and getting his hands dirty when I needed to make a mechanical adjustment to the car - not what I expected from a mapper but certainly shows more of a genuine interest in the success of a customers build! Top man! Also big thanks to everyone else that I leeched information from throughout the build and to this forum for without it, the people on it and the information stored in it I don't think I would have had a cat in hell's chance doing this on my own! I'll shut up now and leave you with a small vid! Cheers. Lee. NM-KqHjqfCg

Is that a friendly offer or a threat? Either way, looks like I'm in for a action packed evening
