Awesome that thing should be mental! Being in the Honda Boost 500hp+ club myself all i can say is this is going to be mental, but we already know that!

Are you going to do anything to the head so you can rev it higher? Revs + Boost = WIN WIN biggrin

Cant wait to see progress, mapping boost by gear might help in the lower gears.

Sorry for the lack of updates, but we are waiting on parts really, rear uprights are still in the planning stage...



waiting on spot calipers from hi spec, but they have a two week lead time frown and the engine block is off being stripped. I'm sure once all parts are in place things will happen faster smile

Ok, looks like darren has finalised the front uprights...



"redesigned the front uprights today to sort out the lower ball joint issue. have done it as a seperate bolt in plinth so that it can be dissasembled and the taper can be removed off the car in a press ect.

i did in the end decided to do the plinth in alloy not steel, its strength is fine as it will all be machined in aircraft spec alloy anyway."

Should be fine, after all it won't be going round a corner any quicker really will it! Just A LOT faster in a straight line!

Torque should be somewhere around 350-375 ftlb, will be revving to 7800-8000 rpm.

With regards, to weight not sure really, I'm guessing a STD S1 exige weighs around 775kg we've stripped out a bit but added in some as well, although the wheels are a fair bit lighter and the ally bits will save some, so I'll take a stab at 800kg dead.

engine came back from vapour blasting today.
back on the cnc to drill out the head bolts for larger items (would have done this the last time it was on the machine but we had to have a roll tap ordered up as there wasnt one off the shelf)


then down to the fab shop, block heated up, o-rings fitted, plenty of extra special sealer as i dont trust just the o-rings, and the liners are dropped into place


then the jig tophats are placed into the bores and the whole lot is clamped down hella tight!



will leave this to go off over night, then it will come off, go back on the machine for block facing, it will have its deck plate fitted and have its final bore and hone.

Awesome project mate.

Are those calipers for the handbrake per chance?
