The plan from the outset discussed by Stu and myself was to put this engine in my own 3dr for the purposes of testing. This way the engine could use all my anciliaries and thus the only thing on test is the std engine. We planned on taking this engine to the point of destruction and as such the major risk is my turbo (i.e. if shrapnel goes down the exhaust manifold. To this extent this project is only viable if we have a donar turbo since I'm not prepared to risk losing my own turbo. If we could raise the funds to buy a turbo then if it doesnt get destroyed in testing it could be raffled off along with the engine.

Karl : Hey, good to see you online.
Your just panicking that you'll miss out on modifying my head. Lol.....
Did you get my e-mail...... Been in contact with Vince, he has two ideas, can I call you some time tomorrow ????

Me Thinks 480/500bhp and 400lbs Torque.
The main flaw will be the lack of a modified head, but I recently saw a Graham Goode Group A Head, and to honest, the ports weren't that much bigger than a standard head, (but very bling).

Sounds interesting, Id have said small head ports dont nessesarily mean the restriction to making big power, I reacon the main thing this engine will be limited by is the valvetrain.
Cant wait to see how it pans out.

LOL......ok so basically lets say the only thing std is head and block from a 4x4....on a big turbo like a GT40 you be making peak power at the rev limit 8000rpm.....the port sizes are std so with ultra good boost control the surge is eliminated....std cams....unfortunately the only death of this engine is thru poor mapping either in fuel or ignition..as i said you will get to a certain boost pressure and no matter how much more boost you put in it will not increase in bhp..so basically a crap idea 
..please for the good of YB tuning just use a stock bottom end...hang on scrap that as its proven to withstand 800bhp..and you aint got enuff donaters to go further (unless you use the profit from PF???)...please scrap this thread ROFL

What makes you think itl peak at 8k Phil? And even if it does, if the powers there way before that, its a helluva engine...
And that boost thing you said, about it not getting more power no matter how much you increase the boost, well thats not engine specific unless you hit the flow limit of the head (and you wont), thats purely down to what turbo you use, how it flows, and how efficient it is.

This should be a very interesting project especially as I've been bending Andys(rsnissan) ear about doing something very similar with his 3dr
We were thinking along the lines of his standard yb lump with a wrc multilayer head gasket fitted,one of mikes manifolds,rs500 throttle body, secs 8 ecu, 750cc injectors, group a fuel pump,rs500 cooler, 2wd exhaust manifold modified for external gate and a gt30 or gt35 running 25psi to see around 450bhp reasonably reliably aswell due to the low(ish) boost pressure the only problem I could see would be whether the head would be able to flow enough air or not
In the Us they get our gtir engines well over 500whp with this approach and our pistons are shit so with the yb engine this should be a doddle

You wont get to the limit of the head i dont think. Head port sizes are not the issue people think they are on turbos, providing you running the right turbo, and providing your car revs sufficiently high.
Gingas got a point about the SR20s in the US, thats another one to add to my list of examples, lol.
They even get over 400@wheels from shonky standard Dodge/Chrystler Neon engines...

this sounds fookin cool idea
i have a brand new mitsubishi gto turbo , totally useless for this i know but i am willing to donate it so you could maybee chop it in as a part exchange for a decent turbo ( maybee stu could swap it with me for a years worth of gold membership )

Even keeping the standard valve train, if an 8k rev ceiling is being considered, the standard valve springs will go coil bound and will lunch themselves, so you would need Iskeys or some such at the very least 
.
It would still be interesting though, but how would you find a standard engine? Most have, by now, had the heads skimmed (several times ) and will be runnng HIGHER than standard c/r. Also, using an old shonky worn out engine isn't going to tell you what a brand new standard engine would be able to take (which is why the bolt on parts work so well in the US etc - they're done to brand new cars ).

I must say, there is someone that is conspicuous by his absence on this topic
He is prob shaking is head it total disbelief that Stu/Karl would even atempt something like this............
CLUE: He said on the other thread that 440 BHP would be the MAX that can be expected
Who am I reffering too?????

Are you refering to someone who likes to give his opinions but seems to have absolutley no knowlege of tuning in the slightest?
EDIT! I thought you meant IMA not Mickey Rainbow

Doug,
You are obviously another person who can't read, I said (in reply to Danny ) that 440bhp would be the limit IF A 4x4 exhaust manifold and 2wd INLET were used . LEARN TO READ .
And seeing as 701s haven't been available for about 2 years, I doubt I'd be able to provide any more than 3 (and that would be by buying them off that guy that got some mixed up with 071s by mistake ).

As time goes by, whether Stu and Karl will make this build, the power-reading will be available. Theres no interest in guessing. As guessings of this kind requires some actual trustworthy basis of these assumptions. Please present any such theories with a good amount of facts and clear describal of thought, if you insist. Horsepower guessings is tiresome...

Cant help noticing that the ONLY people that are saying that
we will struggle to get more than 440 - 480 BHP are those
that have got that sort of power already:
Phil (IMA)
Mike R
Simon
Everybody else is much more open minded

IIRC, MADRods OLD engine used standard sized ports, hence why it made HUUUUUUGE torque (496lbs/ft ish) and 500 BHP but needed lots of boost to make the power , I personally think that stu's point about the turbine of the turbo restricting the exhaust is a much bigger power-cap than the port sizes of a standard head this is a very project though, and if any help is needed spannering/lifiting/fitting/making cups of tea, give me a shout
