  1. I've owned my Supra MK4 for 20 years now and in that time, I had grown to enjoy working on this engine so much that I went on to add a couple of more 2JZ cars to the garage. (Aristo 161, E36 2JZ). During my tenure of owning these cars I have bought and installed; the HKS 264 cams, the GSC S1 cams and the Kelford 260 cams. The Kelfords were my last purchase and the quality has been a bit of a shocker to me. Once I received them, I noticed that the overall quality of the casting looked quite poor in comparison to the OEM and HKS cams (GSC is billet). I proceeded to install them in my engine. However upon closer inspection I noticed what appeared to be a hairline crack at the edge, on the front tip adjoining the sprocket locating pin. As I felt the crack with my finger, a small piece where the crack originated fell apart. It seems like a stress crack while machining the dowel pin. Kelford refuse to acknowledge that it could be a manufacturing defect and insist that it happened in transit or during installation.
  2. Yes, I am on the UK Aristo FB page, however, I haven't updated this build on there yet. What have you been looking for in particular, the downpipe or the high flow turbos?
  3. The stock downpipe is made from segments of cast iron and this unit replaces the entire length. The unit seems to be well made using mild steel. It has a larger inner diameter as well as a larger valve, both of which significantly improve the flow of exhaust gases. Attaching a few pictures from Kurts jz customs; First picture is of it installed, second picture comparing the new valve and stock valve.
  4. I dont think there should have been an issue with cooling if you were going with a CW smic. Will keep you posted on the progress, however this is the stage 3 and is rated well below the stage 4 (now discontinued).
  5. I just received the revised down pipe designed and made by Kurts jz customs which I will be pairing with the new turbo setup. This is supposed to help get a little more power out of the high flow turbos. This also has the valve that is necessary for sequential operation of the turbos. I believe these are designed to fit the Supra, and since this project is an Aristo, I assume I may have to make some modifications to this pipe. Will get some updates once they are installed.
  6. I used to run the Power Enterprise 650cc in my Supra with the Autronic SM4 ECU and it was hard to fault, it ran very well! I currently have the Power Enterprise 800cc in my Supra and it is still very good, however I would say the idle quality on the 650's were a tad better. I cant fault either of them in my experience with the ECU I run.
  7. Having been on a quest to find genuine PE / SARD / Denso side feed drop in injectors for a new 2JZ project, I stumbled upon a vendor (iperformance.racing) on ebay with fantastic ratings claiming to sell genuine 800cc Denso units and after he assured me that they were genuine, I proceeded to buy a set. However, upon testing it turned out that two out of the six injectors were faulty which clearly indicates that they are Chinese copies. Hence, this is just a warning for anyone who might fall victim like I have.
  8. Yes indeed, considering the Aristo is an automatic, I decided to go with a Link Kurofune which is basically Link's G4+ platform ecu which plugs into the HKS F-con harness that is widely available for most of the JDM cars. I am running the Link in parallel to the stock ECU where the former will be controlling; fuel, ignition, VVTI, boost and the latter will control the auto box and sequential turbo operation (vsv's). The Kurofune seems to be a good option for such a setup as it has several Analog outputs which are basically 0-5v outputs that can be setup to emulate certain factory sensors which if removed may cause havoc with the stock ECU while running in parallel. I have used this for the stock; MAF, MAP and for the IAT sensor, I have just hard wired in a resistor as it is an NTC sensor. I had to modify some of the wiring harness for certain functions and unfortunately I did not document the process with very many pictures. Here are the only few pictures I have of it: As for the fuelling, I made a mistake of selling a set of spare Power Enterprise 650cc drop-in injectors just before this project begun and I now need to figure out an alternate solution. It seems like the only option is to go for top feed injectors as genuine drop in injectors (PE / SARD / Denso) 650cc & 800cc are no longer available. I made the mistake of buying a set of 800cc 'drop-in' injectors from iperformance.racing which I was assured to be genuine Denso, however upon testing, it turned out that two of the injectors were faulty. So basically they are cheap Chinese rubbish which belong in the bin. For the fuel pump, I have gone with the Walbro GSS352G3 which should be plenty for my requirement.
  9. Similar to the Supra, a common issue with cars of this age is the significant deterioration of the stock intercoolers. As soon as I noticed that my stock intercooler was in bad shape, I decided to fabricate a side mount intercooler using a Bell intercooler core. The core I chose is slightly larger in dimension to the OEM core and is rated to flow 1038 CFM (I don’t know what the OEM flows) and considering it is a bar and plate design I assume it should flow more. I've also redesigned the bottom pipe section of the intercooler to minimise the major restriction seen in the OEM intercooler. I decided against an FMIC as I wanted to keep the stock cooling system working well and wanted to use all the stock intercooler piping. Perhaps this may not be a major concern in the UK, however as I live in India, our weather is warm for a large part of the year (daytime temperature between 25-38 deg C) and as such I have experienced overheating in my Supra which has an FMIC.
  10. In the summer of 2021 while the initial covid lockdowns were in place, I came across what I thought was a good deal on a 1999 Toyota Aristo Gen-2 and I ended up buying the car. With free time on my hands I begun dreaming up plans to make the car more powerful and my idea came into fruition once I realised that the stock turbos on the car were leaking oil quite badly. Having already built a single turbo (6466) Supra, I thought I would try a slightly different route with the Aristo and made the decision to go with a Stage 3 high flow sequential twin turbos from Glenn Munro of Munro Racing Turbochargers (Australia) I did a lot of research and heard mostly good things about his work, furthermore, he has also always been great in communication and has responded to my numerous questions regarding the high flow options. Will update this thread with the progress! Turbo Specs: Overhauled and high flowed with 46.5 mm Billet Compressor wheels (stock JDM twins 37mm) Cropped inconel turbine wheels. Enlarged wastegate valve(32mm) and large can heavy duty actuator (ct26) for better valve opening at lower Boost. Controls boost well from 14psi. Approximate output rating 375 rwhp - 430 rwhp (Based on 20-25 psi with a stock engine (unopened),with supporting mods and an average reading dyno)
  11. Hi there! I have a set of top feed Siemens Deka injectors (107961) which have a height of 60mm. Will this fit in a 2JZGTE VVTI in the limited space between the upper intake manifold and the lower manifold? Any help would be much appreciated
  12. Hi guys, I ve just had a fresh custom engine wiring loom built by Tweak'd Performance and while they got most things right, they have forgotten to install a tap for the TPS and RPM signal for the HKS EVC6. I am not keen to be hacking into the new loom and was wondering if I can just have those two signals disconnected and still have a functioning boost controller? Thanks in advance Adi
  13. If the core is the same then it shouldn't be a problem. Rebalancing doesn't arise as we wont be dismantling the core. I will try using the spare rear turbo core and swapping the compressor and turbine housings from the broken front turbo.
  14. Hi guys, I have a JZS161 Aristo and the front turbo compressor wheels have been badly damaged. I am going to take apart the intake system and the turbos and thoroughly inspect them. However, I have a spare #2 rear turbo and wondering if I will be able to swap them? Can I swap just the core and keep the front compressor housing and turbine housing if they are undamaged?
