very cool conversion!

but a bit worried about their goals for engine tuning... 900hp, 11K redline and he reckons it will be as easy to drive as a standard car!? how many laps is it going to last at 11K rpm... if you brought the redline down to make it reliable it would be lag city with a T51 on 2.6L

EDIT: beat me to it sav man

Wow that is insane! But yeah like others have said, the turbo choice for a car like that is a bit strange, surely something with a powerband a bit lower would be far more reliable and just as bloody quick in a car like that.

When I 1st started reading it I thought,,,Ah Ben's taking the piss,,,AGAIN,,,Paddy the Irish-man.

I'm now thinking these guys are on drugs.

"It also will have a power band of over 5000 rpms so it will be vary easy to drive.

It will start spooling at 3k and be at max 2.5 bar boost by 5k the cams we have will hold the power all the way to 10k so it will never be out of the power band on any track even if your in the wrong gear.

It will have 11.5:1 static compression. The dynamic figure i wont be disclosing sorry.

You need your engine to be at maximum cylinder pressure between 9-15 degrees ATDC. The only way to do this is by having the right compression ratio and ign timing mixed. Altering one more than the other only results in premature big end failures.

The car will run on E85 for now. Quality dependent. The comp ratio will allow the use of 95 ron fuel with max 2.0 bar boost. Quality dependent.

The RPM limit will be 11k.

My current GTR engine has being doing 10,500 rpms for 4 years and when inspected has never shown any sign of high frequency harmonic vibration etching on the bearings. This engine has a better harmonically designed crankshaft so it should be better".

I'm having a few problems digesting some of these statements.

This thing is going to be a mental thing to drive,,,paddy is going to need more than 1 roll of shit paper,,,maybe 12.

Hope they cut out all the standard Alfa rust!!!

Neil.

    • R34DE as in R34 with an RB25DE? So did you get this? Or you planning to?  I'm not really sure what you're saying. 
    • Possibly avoid using a Cometic one unless the deck/head surface are perfectly flat. I did have a look just then and forgiving gaskets such as Tomei or Nitto don't exist for the FJ20, however the Bar-Tek or Kameari ones look good and might do the trick.
    • Because pipe threads for pipe things. M threads for bolt things. Throw some teflon sealant onto it and dust your hands off knowing you did the right thing, instead of going twice around the block to achieve a result using the wrong things. Of course, all of these solutions are ignoring the fact that the minimum thread pitch we're talking about here is 1.25mm, with the 1/4" in NPT or BPS being out around 1.4mm. You will need to know that the boss you're tapping has enough thickness for at least a few threads. That's one of the reasons that 1/8" is commonly used - because the pitch is <1mm. And why would you look to use 1/4" NPT in a BSP country anyway? Ugh.
    • Just throwing around ideas, does it need to be in the compressor cover? Why not the hot side piping?
    • 1/8NPT drill size = 8.7mm. Since the hole got messed up by me, it’s probably around 9mm.    So 1/4” NPT would be next step. A drill size of around 11mm would be preferred there which is not way of my M12 (drill 10.5mm and tap M12 threads)
