hybrid 1039 Report post Posted March 6, 2007 its an m20b25 that has had _a lot_ of money spent on the head to get it to flow properly to get the CFM up so they didnt have to run as much boost .. (around 25psi) Welded the water channels / jackets to stop the block crumbling under boost and obviously its forged. You still would be better buying an m50 non vanos and turboing that. It would work out cheaper as its 24 valves not 12 valve and would would spend every waking hour working out how to get the same flow outta 12 valves. more boost isnt everything remember you just end up dumping silly amount of fuel to keep the thing from going pop.

Boost Junky 1 Report post Posted March 6, 2007 Yea i would much prefer M50 being 24V DOHC etc.. Just a matter of finding one at a good price. Quote Share this post Link to post Share on other sites

Andrew 30 Report post Posted March 6, 2007 an of course you NEED a Holset turbo bigger than your head - that really is mandatory in sweden. Quote Share this post Link to post Share on other sites
Boost Junky 1 Report post Posted March 7, 2007 Haha of course, im going to put a descent sized hair dryer along side my motor Quote Share this post Link to post Share on other sites
hybrid 1039 Report post Posted March 7, 2007 hehe im looking into a garret GT42r it all depends on the flow rate though .. no point sticking to bigger turbo on .. screw having a boost threshold at 5.5kRPM and having to run 25 -30 psi just to push spin the thing. Also no point having a smaller turbo and topping out the engines HP potential just because the turbo isnt generating enough balls Quote Share this post Link to post Share on other sites
