love the work brought a smile to my face as well. would love to run my cab with that power. thanks for sharing.
I didn't like the mannifold bebore you had it turned to black makes the hole thing look more mean or a gressive I can't wait to see it in the car, would love a video at some point for sound.

Right guys, I have finally finished the revised engine build. Has you know I had a little trouble with number one big end bearing, maybe it from revving it to 8000 rpm, oil temp to high or possibly to tight a tolerance. Anyway I had to decide what I was trying to achieve, the car is mainly going to be used on the road with standard gearbox etc. so I did not really need 700 plus horsepower and huge torque. So having read various threads and comments I decide to go a different route.
I have turned the engine back to three litre, I've taken the compression ratio up to nine to one and have mapped the engine using the Garrett stage five turbo(T350 exhaust wheel, 61 inducer and .82 exhaust housing)
This setup as worked really well I think, especially for road use. It should come on boost well and have loads of usable torque. Below is a dyno sheet and plot for your inspection. The last two recorded pulls have different temp and bara readings because the wastegate pipe broke and we finished it the following night.

I still thing a 2.7 engine is a good way to go, especially if you want to rev, but maybe a dry sump system would be advisable.
Cheers Tim

very impressive! and for the street no less! i love seeing this as it seems like a pet project i'd like to do one day with a spare block and parts…..but if not, then not
so backing it down to 9:1 compression can allow you run 26psi? is that on 93octane pump gas?

No we run 98 octane fuel (super unleaded)

Nice! How, what and where is your intercooler coming?
And how about the oil line, it it your oil feed for the turbo? Where did you get it from, the oilcooler housing?
Thanks!

Nice build. I've seen intake manifolds like that on other builds before and was considering using my spare intake to make one. Do they only provide a benefit at seriously high power outputs, like 400hp plus? Was wondering if there would be any benefit for my supercharged s2.

fantastic build. can't wait to see the video of the car on the road.
look out for the calls for you to put in a brand new coolant reservoir. :-)
can i drop my car off at your place and get a nice heart transplant too? tis the season no?

I have now got the intercooler made and installed. It as a 100mm/4inch bar and plate core, I have a 63mm inlet on the left hand bottom corner and a 70mm outlet on the right hand top corner. I've just got the connection pipes to make.
Its all coming along nicely, I'm also waiting for my flywheel and clutch to be made and I should then soon have her up and running.
Some pictures of intercooler.

Mind if I PM you asking a bunch of technical questions?
Looking at starting a 16v build in 2015, with a 8-12K budget.
Edit: 8-12K budget got the engine & turbo system. Not the car.

i'd love the time and the space to just do it right. love watching it come together. can't wait to see the rwhp number along with the reliability.
in short, looking like a success story in the land of naysayers
