arnout Posted March 31, 2004 Share Posted March 31, 2004 Hi Guys, I'm currently building a new car for dragracing / fun racing here in the Netherlands. I chose to go with the MA60 body, as it's a 6 banger on the license (it's not easily allowed to change the number of pistons in holland). I'm building a 2jz-gte vvti engine in there to be controlled with the AEM ECU. To spool up the big turbo (haven't choosen that one yet) I use the supercharger of a Mercedes SLK 230 (Eaton series). Here is a picture of the setup here is my write up on my site about the project Quote Link to comment Share on other sites More sharing options...
Bobbeh Posted March 31, 2004 Share Posted March 31, 2004 That looks like its gonna be a lot of fun, good luck with it and keep us updated! Quote Link to comment Share on other sites More sharing options...
michael Posted March 31, 2004 Share Posted March 31, 2004 So it's going to be twin charged? Looks like a very interesting project! Quote Link to comment Share on other sites More sharing options...
Ian C Posted March 31, 2004 Share Posted March 31, 2004 Aha, someone talking about twin charging whom I actually believe will end up doing it -Ian Quote Link to comment Share on other sites More sharing options...

Digsy Posted March 31, 2004 Share Posted March 31, 2004 Sweet! So you've binned the ACu, swapped the alternator to the ACU mounts, and put the SC where the alternator used to be? Is that just to keep the intake system simple? What are the drive loads for the SC like compared to the alternator? Good luck with the project! *EDIT* I've stoppe being lazy and actually read some of your site now. Was particulalry gratified to read this on there: "Relocating the alternator was pretty straightforward. It had to be lined up with the water pump pulley, power steering pulley and the main pulley. Note the aluminum pulley on the crank will be removed. These pulleys are bearing / crank killers because they do not damp the vibrations in the crank from the combustion strokes. The alternator doesn't have much of the V belt running over it, so it might slip with high acceleration, anyways, we don't care. We'll be installing a bigger pulley on the alternator soon, solving the problem slightly." Could you install an idler wheel somethwhere to get back to nearly 180 degrees of wrap around the alternator pulley as well? Quote Link to comment Share on other sites More sharing options...
arnout Posted March 31, 2004 Author Share Posted March 31, 2004 Yes we relocated the alternator to where the aircon compressor used to sit. There is NO way you can put the supercharger on the intake side and keep the piping simple. Relocating the alternator is easy. I think the belt will only slip on the alternator on heavy acceleration, but then again, how often do you accelerate 'heavily'? If you do a run you'll be idling for a few minutes after that anyways. So I think we'll forget that idling pulley and give it a try first. Quote Link to comment Share on other sites More sharing options...
Guest Terry S Posted April 1, 2004 Share Posted April 1, 2004 Great project Arnout. Be careful not to make too much low down torque or it will be undrivable. Quote Link to comment Share on other sites More sharing options...
arnout Posted December 15, 2004 Author Share Posted December 15, 2004 I never kept you guys up to date on this.. Here are some pictures of the supercharger with belt, the new V belt for the alternator (see how it would slip over the pulley), the norbie mounts and the R154 mk3 tranny with 1jz bellhouse. The gearing on the supercharger is about 2:1. So the charger will push 2 liter of air every engine revelation until the turbo spools. That means we'll be having around 2/1.5 = 0.33 bar of boost from idle. Should be sufficient. http://www.supras.nl/iB_html/uploads/post-2-42751-mini_blokzij.JPG http://www.supras.nl/iB_html/uploads/post-2-42790-mini_blokvoor.JPG http://www.supras.nl/iB_html/uploads/post-2-42833-mini_hksgate.JPG http://www.supras.nl/iB_html/uploads/post-2-42873-mini_bak.JPG Quote Link to comment Share on other sites More sharing options...

Ian C Posted December 16, 2004 Share Posted December 16, 2004 Excellent stuff .3bar from idle, madness, I wouldn't like to have to park it I love what you've done with the crank pulley to drive the 'charger, will that affect the damping action of it though? Got your intake plumbing sorted out yet? -Ian Quote Link to comment Share on other sites More sharing options...
jagman Posted December 16, 2004 Share Posted December 16, 2004 Nice work,good project, I can see a couple of potential difficulties that may take some thought ref stalling the compressor air,I will re-read your site and put on my thinking cap. good to see people thinking outside the box,and experimenting Quote Link to comment Share on other sites More sharing options...
arnout Posted December 16, 2004 Author Share Posted December 16, 2004 Originally posted by Ian C Excellent stuff .3bar from idle, madness, I wouldn't like to have to park it The supercharger is with a magnetic clutch; we will only engage it when the driver asks for bottom end power.

tDR Posted December 17, 2004 Share Posted December 17, 2004 Nice work arnout Be good to see what you can achieve with such an inventive setup! Cheers, Brian. Quote Link to comment Share on other sites More sharing options...
Barry Posted December 17, 2004 Share Posted December 17, 2004 What a great project! Just out of interest, has anyone ever fitted a VNT turbo to a Supra? One of the guys on the Renault turbo owners club has just done this and can get 10psi just by reving the engine at standstill!! Hits 1 bar at about 1500rpm and is making full boost by about 2400rpm.

Alex Posted December 17, 2004 Share Posted December 17, 2004 Thought they only made VNT's upto T-25 size? Which is far too small for a single T application on a Supra.. Quote Link to comment Share on other sites More sharing options...
cashpoint Posted December 17, 2004 Share Posted December 17, 2004 What's a VNT turbo? i.e what the difference between it and a std t25. Quote Link to comment Share on other sites More sharing options...
Barry Posted December 17, 2004 Share Posted December 17, 2004 The one that was fitted to the 5 was a T3, think they are a 60mm inlet? What size do people use on the smaller single conversions? Quote Link to comment Share on other sites More sharing options...
tDR Posted December 17, 2004 Share Posted December 17, 2004 Thought there was problems with VNT turbos because they were originally designed for turbo diesel applications and cannot take the higher EGT's from a performance petrol application?

Alex Posted December 17, 2004 Share Posted December 17, 2004 VNT = Variable Nozzle Technology. Google it for more It's basically a system which helps spool a big ish turbo really quickly. It was developed for diesels originally. Quote Link to comment Share on other sites More sharing options...
arnout Posted December 17, 2004 Author Share Posted December 17, 2004 Variable Geometry Turbos are becoming more common but the big size turbos (700 HP somethiing) are still not available for a fair price. Nice thing on the turbos is you don't need a wastegate, as you can control both spool and boost with the blades of the exhaust turbine wheel.

arnout Posted December 22, 2004 Author Share Posted December 22, 2004 Today I dropped the engine in my car: http://www.supras.nl/iB_html/uploads/post-2-46963-mini_enginebay1.jpg http://www.supras.nl/iB_html/uploads/post-2-46979-mini_enginebay2.jpg http://www.supras.nl/iB_html/uploads/post-2-46995-mini_enginebay3.jpg http://www.supras.nl/iB_html/uploads/post-2-47021-mini_enginemount.jpg http://www.supras.nl/iB_html/uploads/post-2-47047-mini_spannercharger1.jpg http://www.supras.nl/iB_html/uploads/post-2-47075-mini_spannercharger2.jpg http://www.supras.nl/iB_html/uploads/post-2-47111-mini_bodycut.jpg http://www.supras.nl/iB_html/uploads/post-2-47134-mini_suckmyweasel1.jpg http://www.supras.nl/iB_html/uploads/post-2-47147-mini_suckmyweasel2.jpg Quote Link to comment Share on other sites More sharing options...

arnout Posted May 1, 2005 Author Share Posted May 1, 2005 Here is an old update: Ok here is a slight update on the project. As stated before we will change the complete rear of the car using a RA60/TA60 floorplan which is solid axle. The small solid axle will be replaced with one of a hilux / hiace (5 bolt / G differential). Here is the car with the donor floorplan: http://www.supras.nl/iB_html/uploads/post-2-85368-bjorn2.JPG The next picture shows the solid rear axle on the donor floorplan: http://www.supras.nl/iB_html/uploads/post-2-85897-bjorn15.JPG Here we are removing the rear from the car http://www.supras.nl/iB_html/uploads/post-2-85578-bjorn6.JPG Voila, the wheels on the floor http://www.supras.nl/iB_html/uploads/post-2-86153-bjorn25.JPG And the independant rear suspension is gone. http://www.supras.nl/iB_html/uploads/post-2-86209-bjorn27.JPG Let's see when the solid axle goes in! We've also been working on getting the TH-350 to fit the 2jz. Originally our plan was a R154, but more research resulted in the 3-speed automatic decision. We made an adapter plate on the oil pump, seen in someones post on supramania (we made the plate ourselves cause his was not available for sale)": http://www.supras.nl/iB_html/uploads/post-2-55489-DSCF0001.JPG Sideview: http://www.supras.nl/iB_html/uploads/post-2-55511-DSCF0006.JPG Adapterplate: http://www.supras.nl/iB_html/uploads/post-2-55558-DSCF0005.JPG Quote Link to comment Share on other sites More sharing options...
arnout Posted May 1, 2005 Author Share Posted May 1, 2005 and here is a new update of this weekend: here are some more pictures on the solid axle conversion. We use the hilux axle and the celica RA/TA60 floorplan. http://www.supras.nl/iB_html/uploads/post-2-74717-achteras1.jpg http://www.supras.nl/iB_html/uploads/post-2-74815-bodemplaat.jpg the most complex 5 bolt conversion ever: http://www.supras.nl/iB_html/uploads/post-2-74920-5bouts.jpg axle under the car: http://www.supras.nl/iB_html/uploads/post-2-75099-asonderauto.jpg Quote Link to comment Share on other sites More sharing options...
