One other quick question, does anybody know which way the K series rotates or which side is the thrust side of the engine?

Yup, if you're looking at the engine front (with the cam drive gear) it will rotate clockwise :thumbsup

Thought so, just never thought to look before when it was running. Odd how there is no mention of rotation direction in the manual. Ho hum, cheers Steve. Got your up and running yet?

Pretty much every IC engine these days apart from some Honda engines (not the K20) rotate clockwise.

Unless things have changed, rods and pistons ware fairly straight forward. The lightest rod and piston were the benchmark and the other three were bought down to its weight. They will be done in pairs with weight being taken off the heavier side if it can be measured

I would think that they have a computerised machine to measure rotational imbalance nowadays, but it will still be the same principal of removing weight from the counterbalances or adding it if necessary. Similar story with the flywheel, lightened and balanced.

They should also carry out dynamic balancing, but not sure what that involves. As you have an accurately ported and gas flowed head, you compression ratio between cylinders should match pretty closely. They would also check the camshafts for uneven wear but this will not apply to you.

Used to be called blueprinting but not heard that used for a while.

Another couple of jobs knocked off the list today. Changed out all the springs on my Nitrons dropping the spring rate 100lbs all round and changing from Nitron springs to Eibach

Image

Once the dampener is off the car and in the vice, wind off the lower spring platform to release the spring tension...............

Image

Turn it upside down (actually the right way up........ but never mind) and remove the circlip

Image

that sits in this groove and retains the upper spring platform and remove it and the old spring.

Image

Old and new side by side.

Image

Took the time to remove the old ARB drop links which was the one job I never managed to do last year when replacing/refreshing the suspension.

Image

The finished article, will of course need to geo the car once she is back together but should improve the ride quality on the road and be plenty stiff enough for the track etc. Reason for changing them was because with the 2 ways I was running hardly any dampening either on the the track or on the road. Having spoken to Nitron it is possible the guy I got the shocks from had them valved differently from standard, will have to wait and see what they feel like now. One point of note was that the new rear springs are 2 inches longer than the old ones which is a bit odd but looks right now with the spring platform nearer the top than the bottom.

Back to Dundee in the morning to pick up my bits & bobs from balancing, so will be building the engine over the next day or two. Away to strip out the pedal box and steering column and fit the new trunion bearings and rack riser plates. Not looking forward to this as the pedal box is a pain in the a**e to get out but needs doing so ho hum.

Also changed out the front calipers for the new ones and overhauled the rears and fitted the PRRT in place.

Some more pic's of work done/ in progress.

Image

Rear dampener with longer Eibach, before the top spring platform was about 2 inches above the end of the thread on the body.

Image

PRRT waiting for an engine...............

Image

New front caliper fitted.

Image

After much cursing finally got this bad boy out. Took it out with the brake and clutch cylinders on it because I think it is easier to bleed the brakes/clutch than try and get the cylinders off while upside down in the foot well of the car. Marked up and split the intermediate steering column shaft. Undid the pipes for brakes and clutch. removed the stop bolt for the throttle, it doesn't mention this in the manual but you will not get the peddle box out without first removing the stop bolt. Removed throttle cable, stop light switch and dropped the throttle linkage plate out of the way. Undo 6 little bolts, they are a real tw*t to get out, and then wrestle the pedal box out........easy :rage.

Image

Undo these two bolts allows removal of the main shaft, but that will be tomorrow.

Image

All to replace this trunion insert. It doesn't look to bad but I know it's split through where you see the mark on it's edge. Clutch pedal creeks like a good 'un so time to change it before it wrecks the pedal itself.

Mike

The U bracket on the throttle pedal looks like the original thin one, which snapped in two on N1. I replaced it with the upgraded later one which is much thicker.

Stripped the pedal box today..................

Image

All the bits laid out...............

Image

The clutch pedal with the bushes and trunion that needs changing. Undo the grub screw and back out the push rod.

Image

Trunion and bushes then just push out...................

Image

The knackered bush..............

Image

The new ones ready to be fitted

Image

Push in the bushes and make sure they are square to the edge, push the trunion into place and refit the push rod and don't forget the grub screw. Once preload on the clutch master cylinder is set, loctite the grub screw in place. Rebuilding the pedal box is a bit futtery but the manual shows where everything goes. :thumbsup

Next up................. ENGINE.

First off was cleaning all the block ready for fitting the big ends. Using Millers rebuild lub along with Molykote on the crank. i am a bit concerned that the Moly and/or the Millers has made the engine a bit tighter than it was, but more on this later.................

Image

Block with it's mains in place

Image

Crank been coated with Moly and drying, after which I polished it all but forgot to take a picture.


Image

Mains coated with Millers, this stuff is like syrup really thick hope it does the trick.


Image

Same for the bearing ladder, here dry but about to get the same as the block, least it doesn't run off like oil. For those in the know, bearings ended up being a blues in the block and blue, red, red, blue, red in the ladder.


Image

Crank in and ladder on.


Image

At this point I kinda side tracked and decided to fit the oil pump and................

Image

................. then the water pump. God knows why, but suppose it needed doing at some point.


Image

Then my head went completely up my a%%e and I prep'ed the oil rail, then noticed I hadn't fitted the pistons or liners :oops: . So wiped of the sealant and set about the liners.


Image

A continuous 2mm bead.......... ye right, have they ever tried getting a 2 mm bead out of a tube of blue. Anyway, after a couple of goes it looked OK and in it went.


Image

Followed by the pistons which I had built up earlier. After coming back from balance just need refitting to the rods, again with plenty Millers.


Image

Guess what, didn't have any liner clamps and couldn't be bothered trying to make some. Nothing wrong with wood and tie wraps anyway. It did the job but I wouldn't do it this way again, was panicking that the liners would move.


Image

Which they didn't seem to looking at he bead of sealant showing.

Image

Fit the MLS head gasket on advice from Rog..................

Image

Took the cams out really just to make it easier to handle and be able to see the bolt heads more clearly.

Image

New LR bolts, oiled the threads and under the heads..............


Image

.......... before torquing to first stage.

Image

Marked up ready for the 2 x 180 turns.

Image

Semi finished article. Stuck the flywheel on to turn the engine over, this was when I discovered that the engine is hell of a tight. Now this is either the miller being so thick or the extra thickness the moly adds although I doubt that. After a couple of turns it did free up so it should be good once oil has got through everything and flushed out the assembly lub. To be expected really as it is very viscose.
Anyway ploded on and fitted the oil filter housing to finish up the day

Image

Looks loverly :thumbsup

Questions: How much sealant are you supposed to use as I don't seem to get very much out of the stupid little 10ml bottles, or am I being to liberal with it ?. Probably need to get more for the cam ladder and sump. Be a while before I fit it anyway as I waiting for lakeside to send a baffle, might be here by the end of the week.

Sorted the ignition coil thing out, Exige S1 VHPD coil is 3 wire in 4 out so have got one of them, one extra wire to run job done :thumbsup

Trying to decide weather to run a map sensor or not thoughts and comments welcome. I fact if you have any advice comments on the above fill yer boots




Tomorrow cams and cam timing.....................

Nice work Mike! I've got to admit this is my favourite thread at the moment. Only problem is it takes me over an hour to load all these photos (slow as fcuk middle of nowhere Indian internet conection) but still keep them coming. When do you think you'll have it all back together?
