Ah ok that makes more sense. Bloody black magic those converter! ;)

I won't attempt to argue he doesn't know what he's doing but the move to a hemi head over pent roof seems a strange one? Especially for a boosted engine? Easier access to tuning knowledge/experience I guess, but the stock chamber should theoretically deliver a better result? Awesome commitment...

Billet heads! Sweet! So which bits have you changed? Port angles? Combustion chamber?

Hmmm tempting. Have single T 2J that would like this this telling it what to do :)

I had the bigger M122 on one of these using the stock fuel rails....no issues that I recall?

Evo diffuser plate injectors are still available.

yeah plumber LOL ....not :) No extra plumbing over the TT setup. Folow the link to my thread and there should be pics in there of all my various combos...if the site didn't stuff up too many of them when it crashed. i ran my own bitsa kit comprising a big Surflow pump and nozzles from...

No pinging...good tuning ;) M90 was with TT also :P M122 ran 16-17 psi with no hint of det on E85 and water/eth injection as the intercooler. It stated out at 270rwkw and with more water/eth topped out around 300rwkw...a weapon to drive but hell noisy on big boost

All sounds reasonable to me and totally agree that engine control wise, ECU are far from equal and engine control is more important than bells and whistles for me. Results Off the top of my head with the twin KKKs turbos ( hybrid k27/26) Stock engine/stock inlet/98 fuel 6.5psi - 265rwkw 12psi...

Yeah no offence taken Jake, great info and obviously a wealth of experience. Not having played with boats I just made an assumption based mainly on the much lighter weight....assumption is always risky ;) My humble efforts are based around being fairly conservative given i don't have access to...

ah i hate no edit button....that was supposed to be "stock engine" not "stock n/a". I was running 17psi at the time on the KKK twins.

If you are upgrading internals then sky's the limit pretty much. In stock form the pistons are tough, but they are still designed for n/a with relatively small ring lands...they don't like det or the heat you get from high boost. 450rwhp is a safe figure for the street with a good tune and...

It'll run at 450rwhp forever on the street with a conservative tune

A long time since posting so... It's a bit of a metal mountain because the 2UZ manifold is so high, but it does fit under the bonnet...just! Progress on the cascade of small jobs that have suddenly appeared :rolleyes: so I'm getting there.

Nope sorry, no spares just sets of 8

7m injectors sold sorry

Buy Bullet inlet and my Kenne Bell 2.6......name a power lever and this will make it ;)

No one wants slow though ;)

I think you'll find there's a good 500kg difference between a Surf and your Rolls ;) and a surf is no performer with a UZ....gearing helps a surf but you have much taller ratios. It'll be slow plain and simple. Your proj, so hope you get the result you are after.

Boosted will awesome. Not boosted will be disappointing I think? It's only a little 4 litre and doesn't really have the torque to lug a 2 tonne Rolls around.
