hi to all fellow m42 e30 owners. i got a question to u who had gone through the process of rebuild. i'm following bentleys manual and i cant locate where does a part numb 1111 1734667 go.it's a non return valve and it should go together with a spacer numb 1111 1739185. bentley says it goes in the hole in the block but it cant fit there. i wonder if anyone knows the solution

Thanks for the pn, nick!
I would be curious to know which heads got the smaller lifters!-Nick

I was thinking about getting a little more in depth than head studs and a tune. I was looking at a budget of around $3k including an engine refresh. I'd really like to be closer to the 250 whp range.
I want something that won't have me thinking I should have just thrown in an s52 and called it a day.sigpic

No amount of engine building can save you from a crappy tune. For whatever reason people seem to overlook that and think some magic array of parts will protect from a poor tune. This is not the case.
Getting a quality turbo is one of the best places to spend your money. Youll get so much more out of this than buying needless engine internals.-Nick

I have no problem using the stock internals as long as they will reliably hold up to my power goals assuming I have a good tune.
The motor I want to use has around 160k on it but I ran it very low oil a while back because I didn't get the oil canister lid sealed on very well. Now it is eating some oil but seems to run fine. Have taken it on a couple 4+ hr trips since then and drive it almost every day.
I thought I would tear it down and possibly get it re-honed with new rings. Maybe o-ring the block and get the head refreshed. I was planning to looking to upgrades to things like the valves and lifters. I am at the beginning of my research for this project.
I don't have it all figured out yet. I just know I want around 250 reliable hp and I want to learn about turbo's. The less money it takes to get there, the better but I'd like to stay under $3k if possible. I like the kit that was linked but would like a little more power and the manifold seems a bit restrictive with those t's.sigpic

You can easily hit that power level on stock internals, although replacing the bearings, rings, and giving it a hone is an excellent idea. Thats basically what I did on mine.
I agree the manifold with Jakes kit leaves a lot to be desired. I would much prefer to use one from Otis (Good&Tight).
Upgrading the valves and lifters will not be a good bang for the buck honestly. Put that money into engine management, turbo & tune to get the best results.-Nick
