      This is going to be a very (very) slow build log for my new project. I plan on retrofitting the 2.5 motor in to my r32 shell, and push it over 1000 all wheel horsepower.

      Fueling: ID 2000s, Magnafuel Mp-4703 in custom surge tank fed by walbro 255 fit in OE fuel pump basket., E85
      Spark: ls2 truck coils
      Turbo: custom tubular exhaust manifold, Holset hx52 pro (will upgrade to 60 if need be), 4.5 turndown to dual 3"
      Software: vems

      This build is going to be really, really (did I say really?) slow. I travel for work 8-9 months out of the year. The engine was delivered today, and I will be turning home the first or second week of January to tear down, and send the head out for porting and crank out for knife-edging & flywheel modification. The goal is to have all the hardware in place and ready to assemble when I get back in June.







      Looks pretty good for an advertized 170,000 miles. I'm thinking that might have been a typo, and it's 17,000. Engine is an 08 CBUA.

      Sub'd for build. I've seen an HX52 put out 650+hp on a conservative build, I bet you can reach the 1000hp mark or very close to it. Good luck, keep us updated

      And def not on the stock crank. I think the others have approached the limits by building it up as solid as they can and see what power it makes. I think right now with current development maybe 700hp

      My first reaction was to think "no way", but as bold as it sounds, maybe it's possible. I wish you the best. I'm very curious to hear your thoughts on what will be necessary in the internals, trans and driveline to hold this. I imagine most everything has to be done.

      Does you R32 shell have AWD driveline still installed?

      EDIT: I guess AWHP gives that away. Assuming then that it's an '04 with 6MT.

      kevin, I'm actually more worried about the block holding up longer than the crank. If the stock forged crank doesn't work out, there's always the TTRS crank. I feel what will be working in my favor is that this is not a race car. It will not see sustained high rpm use. I refuse to call it a **** queen, but I will call it what it is, a toy.

      zevion, it may make some mad, but yes, it's an 04 R, not an 08 or whatever. While I'm jelly of the stiffer chassis, I think the mk5/6 platform is ugly as sin. But that's just, like, my opinion, man.

      Hey that's cool. I love the MkIV. This is a serious build. Please share details as you go, because it would be very interesting.

      3.0l Inline-6 2JZ supra motor..... our 2.5 is half a liter less displacement and minus 1 piston.
      There are plenty of Supras well over 1200hp. With enough money, anything is possible.

      If a 3.0 liter 2JZ is making 1200HP, thats 200hp per cylinder.

      Do the same equation on a 2.5 liter CBTA motor.......... You get 1000 HP.

      Im not saying it is or isn't going to happen, but with the right tools and enough money im sure it could be done.

      I can't say for sure it's possible, but perhaps sleeve the block and overbore? Has it been done? How far can you take a 2.5L? Maybe to 2.7+?

      I know someone made a built block for the 2.5. i think it came out to 2.6. I'm not sure who it was, could have in IE but i really don't remember.

      You cant compare one of the best engines ever designed to a 2.5l Volkswagen economy motor. The 2JZ can see 700whp on stock internals, came as a twin turbo option. I see what your getting at but its not a realistic comparison. It would be better to compare it to a vr6, which 800awhp seems to be the safe limit. I also want to add that some of the highest hp 24v's have been dynod with the haldex fuse out, so the numbers are to the front wheels. I believe BW is one of the only that shows 800awhp on a awd dyno.

      In for the results though. I think the op should just say Im gonna build it all out and see what happens, because even the difference between 7-800awhp and a 1kawhp is extremely substantial in every factor, it will take alot, probably even nitrous

      Sounds like its gonna be an EXTREME build, but def can't wait to see. Def. gonna require alot into the engine itself, and if going just force induction, a good amount of boost. I was planning on building a 5-600hp 2.5 build in the future, but def wanna see what it takes to make power in that range

      I dont believe there is enough material between each cylinder to do a sleeved overbore. ~.1l max imo. Curious though, because the new s/c I got should make around 360-480hp depending on pulley used, so idk maybe this is possible.

      I was looking in to sleeves for a 1.8t build. The only thing I came across was repair sleeving. Punching the block to 83.5 will get you about .06 liter the 2.5. Edit, math to words

      I see it as possible. We have 8vs pushing 600, 1.8ts over 1000, that vr6 corrado is aroubd 1200 on meth. That 3.6 over 1000 with a gt42r. All wheel. The only aftermarket cranks I know of are eurospec and well..... lol

      As far as I can see, only thing holding this engine back is camshafts.

      Idk you have a lot of work, time, and money to put into this build. We'll see what happens

      I think it will be easy. Expensive, but easy. I already have customers doing over 1000 whp on 1.8t's, and this engine is basically superior in every way. Where it is not, it's straight forward to fix.

      If the cranks don't hold up I will make 4340 billets. /story.

      If the block doesn't hold up, get a TT-RS block, which has more webbing.

      If the cranks don't hold up I will make 4340 billets. /story.

      If the block doesn't hold up, get a TT-RS block, which has more webbing.

      Also, sleeving it won't help you get to a bigger displacement. I could fairly easily make a 2.7L crank, but you don't need more then 2.5L for 1000 awhp anyways.
