The rod modification: Bush in small end increased to 24.0xmm Big end reised to ford bearing size New locking grooves where made for ford bearing The big end with was narrowed and also a chamfer was added. Did aslo make a oilspray hole just like ford rods got.... If I am happy with the...

Haven't been in here for ages...... To make a 3.7 version of a 2.9 isn't the best solution, it is very expensive and it will brake. It uses a 2.9 block bored into 95mm, 4.0 crank stroked into 86mm, opel frontera 2.4 pistons, 2.9 rods with a small end bushed into 22mm. There are so much material...

Any one knowing the bolt pattern of the 8 bolted 4.0 crank? Also the guide diameter for the flywheel? And also what thread it is on the bolts? Thanks Tobbe

Update, the engine runs very well, a stock OHV bottom end, CR is 11.x:1, 18bars when doing a compression test. Put the rpm limit to 5200rpm, so it will last a while.... Finnally all the effort is paying off:D

It wasn't a big end, I assumed it was from investigations from the sparkplug hole.... The damages was very limited since the piston still was attached to the rod:D Just minor damages to the pistons, but the rod need a new bush though.... I've sourced another block which I am putting...

How high do you rev your 4.0 ohv engines? Any one going 6500rpm+? I took my engine past 6500, and I got a big end bearing failure as a result:D Back to the garage again, and hopefully I will find another crank..... //Tobbe

No intercooler then...... Build a simple water injection system...... Wouldn't cost much. I saw a nice description somewhere, I'll make sure to find it for you. You will be surprised on how simple it is..... //Tobbe

Have a look at the old turbotechnics conversions..... They are 2.9 12v cologne based, but they could be a good information source, they perform very well. They got an impressive torque curve.... And there is also ONE 2.9 24v version, 530bhp@ 1 bar..... //Tobbe

Got the engine in another car now. Upgraded the gearbox from a T9 to Mt 75, sinter paddle and sachs racing pressure plate for escort cosworth, should cope with almost 800Nm of torque. I have also modifed my injectors so they flow close to 600cc/min. I have replaced the sprocket that drives the...

Some reving behind the steering wheel http://hem.bredband.net/cosworth_96/Granadacosworth.wmv Something from when being on the road mapping when the clutch have failed http://hem.bredband.net/cosworth_96/cosworth.wmv I haven't tested it at full throttle and above 4000rpm yet...

I blew the clutch when I was out on the road mapping it.. I managed to drive it 400km, and I can say that when everything is tuned in, it will run pretty nice....... It's bloody strong...... I estimate I will be back on the road in april with it..... Got a much stronger clutch now:D

Finally, I've assembled the engine and filled her up with oil:D And made some tests and everything looks really good........

Getting closer every day now:D The rods are Procomp 6" for chevy SB, modified to accept ford crank and rod bearing and also a 24.005mm wrist pin (not stock pin). The wrist pin is custom made out of 4340 steel, 61-62 HRC hard.... (try to kill it with a hammer and you'll see which of...

Got me a set of these, And I have also increased the bore a bit.......

Wise guy, I don't need that kind of posting.... I recently found out that they are no stronger then the ohv ones. I am not familiar with the SOCH at all, never seen one, I've just heard that it was supposed to have better internals. Got some other stronger rods now. But I would like to buy a...

Did some work on it yesterday. If someone got a set of SOCH rods for sale let me know, I really need them I think...

The headgasket assembly. The copper fire-rings are still missing

No worries... It will run nice without any problems:D I hope..... I just hope that the bottom end is up to the job. The parts in it is not as strong as the 2.9 cosworth bits.... Time will tell...

Buying the car for the engine on saturday if everything goes as planned, it only weights 1210kg, so 0-60mph should be wrooooom. The head gaskets have been cut, still waiting for the copper for the firerings. Did never buy that SOCH, I got enough to do anyway. Got a slide inlet under...

Hmm, did find a really cheap SOCH, maybe I'll pick that one up and have a closer look at it...... Besides, it's 207bhp enigne, maybe it just need some breathing help, 2xTT conversion might help it a bit.... It's getting to many projects in the garage soon, 4.0 cosworth N/A 2.9 TT cosworth...

Actually, I have heard of a SOCH based engine being built in Norway, it uses 2lhs heads. More I don't know, got this info from a mate in UK. And there is also a guy in Belgium that have plans on a OHV based one, but I haven't heard any more from him. I tried to offer him some help but...

Wonder how it turned out for him, if he ever finished the engine. There's a big differ between his and mine engine, his was BOA based and my is BOB based, meaning different heads, chaindrive and inlet. The only boa stuff I am going to try to use is the thermostat housing, if possible...

Did fail on machining a own helicalgear so the 2.9 stuff had to be modded with bigger journals, and also the distributor dummy plug is used, ofcourse there are some moddes to the lock washer aswell. Got a spare saft from a mate in UK, did also get a few other parts so I still can put the 2.9...
