Keep in mind the MkII head was revised to allow MORE oil to flow to the cam towers (early engines were prone to cam belt ...   10-24-2006 09:47 pm

Oh come on Frank, you gotta replace that Mk I with a suitable MkII block!  I've got a spare Mk II block with your name ...   10-23-2006 08:02 pm

Dan, You can tap the top of the block where it mates the head and screw in the restrictor there.  I use a 3/8" brass screw ...   10-23-2006 01:31 pm

The wheels are made from a magnesium alloy. ...   10-10-2006 12:59 pm

Shhhhh!!!!!! Ron Don't let everyone know our secret!  I'd rather everyone think we're a bunch of amatures. ...   10-05-2006 09:35 pm

Glad to see everyone has an eye for detail! We've actually been having a hard time getting the carb mixtures balanced.  That pic was taken on ...   10-05-2006 01:28 pm

Sander, We all KNOW I've got more than ONE screw loose! Judson ...   10-05-2006 02:12 am

New Engine Oil lines.  Notice the 8AN Accusump line just barely clears the two 10AN oil return and supply lines by about 1/8". ...   10-03-2006 07:18 pm

For those of you racing along with us vicariously, I've attached photos of Ron Earp's car with the new Engine.  Can I tell you how ...   10-03-2006 07:15 pm

I figured you had a good reason for not running the dry-sump.  They are expensive and do take up a great deal of room.  And ...   09-22-2006 01:07 pm

All who are challenged by the 9xx series engine are welcome! Garry Kemp is THE man when it comes to developing high HP 9xx series Lotus ...   09-22-2006 02:29 am

Sylva, That's a pretty neat trick getting the earlier iron liners to fit the later block, especially since the iron liners are smaller than the holes! As ...   09-21-2006 08:13 pm

Norm, As I remember the conversation with Joe Huffaker, that axle was locked and they were running Goodyear slicks on 15"x7" wheels.  Lots of grip, extreme ...   09-03-2006 01:37 pm

NGK BPR6ES is what I'm using in all of my engines.  I gap them .025" to 0.035" based on the ignition system. The gap will be determined ...   08-31-2006 03:30 pm

Al, The problem you are running into is that all repair shops go to their computer to develop estimates.  Many commercial software packages exist to develop ...   08-30-2006 11:48 am

Sorry Ron & Norm.... The 235/5 uses Porsche Synchros and the guys at Metric Mechanic absolutely hate it!  Too bad all of the other BMW 320 ...   08-25-2006 03:12 am

Joel, The JHPS crank & bearing package is as good a deal as you can find.  The Chrysler 318 bearings are NOT a direct fit, and requires ...   08-25-2006 03:00 am

The 235/5 is a rare thing, which makes it special - not necessarily practical.  Before dismissing the Supra conversion, keep in mind Lotus chose this ...   08-21-2006 01:31 am

Glen, There is a BMW guy here in Atlanta who has done several.  Email me if you're interested and I'll see if I can find his contact ...   08-20-2006 12:45 am

John, Sorry to hear your story of woe, but no need to jump to conclusions. The oil could be coming from worn valve guides or worn liners.  No easy way ...   08-17-2006 09:40 pm

As Mark indicates:  Always rotate an engine clockwise For added precaution, squirt a few ounces of Marvel Mystery Oil in the spark plug holes to lubricate the ...   08-15-2006 01:23 am

Use Delta's off-the-shelf JE Flat-top pistons....As you can see below, the pistons can produce a CR range anywhere from  9.5 to 11.5 to 1.   A 0.030" over-bore ...   08-11-2006 07:01 pm

Steve, I hate to give a particular product endorsement as I'm sure you can find a variety of products at your local auto parts store.  ...   07-31-2006 04:42 pm

Steve, I can tell you that when I do customer rebuilds the number one thing I see time and time again is filthy, nasty sludge and ...   07-30-2006 02:17 pm

Steve, The post 1973 907 equipped JHs (aka MkII & JH5) have a removable rear housing and lip-type rear oil seal easily changed (realatively speaking).  Among ...   07-30-2006 01:54 am

Michael, There is an 'OEM' hartop that comes complete with glass window and defroster.  By OEM I'm thinking it was actually a dealer option and fairly rare.  ...   07-19-2006 08:21 pm

Yes Joey, you are correct.  Click on the link I included above and you will see the 910 bottom end is significantly larger.  A 910 ...   07-18-2006 03:55 pm

Erik Harkes put a 907 bottom-end on a 910 top-end.  I went the other direction and put a JH top-end on a 910 bottom-end.  My decision ...   07-18-2006 02:56 am

All me and it was NOT fun!  totally custom with multi colored wires sourced from Home Depot. ...   07-17-2006 10:29 pm

Everyone has different experience and what I've found is every engine seems to like a different jetting. The spitting comes from fuel dropplets dripping on the hot ...   07-17-2006 05:53 pm

I recently parted-out a few cars and have complete used looms. Other than that, you can completely replace your harness with a custom one like I did. ...   07-17-2006 05:34 pm

Brett, You seem to be at least in the right ball-park with jetting.  Exactly what kind of trouble did you have? ...   07-17-2006 03:12 pm

I'm sorry for the confusion Dan.  I agree with Kurt that while you could get a 36mm choke to fit in a DHLA40, it would ...   07-17-2006 11:03 am

It would be better to get a set of 45s if you can, but the 40 can be made to work....just a lot more testing ...   07-17-2006 01:44 am

You can actually get down to 28mm chokes in a DHLA45 and up to 36mm in a DHLA40. Choke size determines maximum amount of flow (assuming ...   07-16-2006 08:29 pm

I seem to remember a few stories about this car showing up on the old board.  Can't be too many JHs w/ a Supercharger! 180hp at ...   07-14-2006 05:24 pm

Ron Earp can comment on the corner weights of his ITS car, but in Solo I trim my car weighed in at Roebling Road ~2,150lbs.  According ...   07-12-2006 01:39 pm

The shop manual is pretty clear in that the only way to remove it is to drill out the tamper-resistant screws.  Ron may have the ...   07-11-2006 02:41 pm
