have had a few good write-ups from G40 owners. Strangely there site doesn't list the micra but I'm guessing it's an 8v head so probably £350 ish for there stage 3 head.

Dave don't like turbos. They don't respond to porting and gas flowing like a N/A motor. The as cast surface finish and any joint mismatches just heat the air a little bit more and cause a very small pressure drop. Think about the stupendous power gain you will get from turning up the boost 0.25~0.5psi - that's about what porting gives you. Far more effective to reduce the intercooler restriction and outlet temp. Only when you want over 200bhp/l will gas flowing be worthwhile and then you need to think about a fabricated inlet manifold as well.

Dave did a great job on one of his customers turbo kit car - im sure you read that? I currently have 170/l and I want to rebuild with the intention to way pass 200/l. I'm running 1.5 bar and with everything else this shall be increased further as well as intercooler and the rest.

Whats with the comment on the inlet manifold?

Hi Thanks for this :) I shall contact them.

Plus there's the possibility of negative and vocal publicity amongst the residents here too... :)

He does your job. You don't like it. You tell us. We never let Dave live it down. Etc.

More of a jest than anything, I'm sure Dave doesn't give a flying f*ck about what any of us in here think as he's made it quite clear what he thinks of his customers (and on that basis alone I personally wouldn't consider using/recommending him, but like I said, I sure he gives not one f*ck).

I got the impression from some past postings that he wasn't too keen on doing another turbo.

The inlet runners and bellmouth inlet in the plenum are just as important as the ports in the head. The bellmouth is usually just a small rad between inlet tract and plenum floor on cast ones, fabricated would have a bigger rad and stand off the plenum floor [1]. The head has about 8cm of port, the manifold looks to have about 25cm or runner, so if you only do the head 3/4's of the inlet is still rough as cast. It looked to have slow 'S' bends on 1 and 4 and all curve up so it's not going to be easy to smooth even though it appears to split just behind the injectors. I can see a core line on no3 runner.

[1] Even a 1974 Honda 500/4 had nice rubber inlet bellmouths on the carbs that extended about 2cm into the air box. Taking the air filter box and inlet rubbers off to fit K&N air filters direct to each carb was a good way to lose power and make noise. Taking the airbox off and just fitting the rubber bellmouths was a good mod for racing. But that is N/A.

You know I understand compleatly where your coming from here. I have read all that and find it very off putting, but at the same time I do trust his skill. I honestly belive he does know exactly what he is doing, where are so many head tuners just dont have a clue, and I really dont want to give my head to somone who may totally screw it up!

I expect you are right. Im going to try some of the other places I have been recommended and see what turns up.

Very interesting advice :) I dont mind looking into totally fabricating a new inlet manifold, I did look at it in medium detail, and its not all that great, hmm you have got me thinking now. Idealy I would like to keep that just as its such a recognisable part of the car. I shall still get the head done, but I would like to also do some thing with that.. hmm :)

Haha :) funny when thing like that happen.
