Cylinder head porting / polishing with 3-angle valve seats is just about finished

Cams are sorted

Mad, bad GT2871RLS turbo has arrived

Forged pistons with ultra-cool "gapless" rings are ready

Special (and pricey) clutch is ordered

bank account is emptied

divorce papers are on the way

Looks like I'm going to have to find someone else to copy

Good luck Nigel

Ooh, look forward to the results.

Any chance of a spin sometime mate? Going through Coupe withdrawl again after Rog phoned me last week with news of my old Coop.

Any pics of this bad boy turbo?

Know the feeling Nigel, mine is also nearing completion . Hopefully should have it back within the next week or so . I haven't replaced the turbo like you, but am hoping to notice the performance difference with the cams and Greddy Profec B, and handling difference with proper camber adjustment and poly bushes at the front .

Just need to get it remapped once it's bedded in, but will probably wait for the tubular manifold GB to resolve itself first...

Phil

Im in the same boat as you 2 guys aswell... getting near my coupe being back on the road. I have balanced pistons and rods, lots of headwork, gapless rings also, and im getting my greddy profec b fitted along with new hub flanges and wheel bearings (to make sure em wheels dont come off again). When you guys getting your cars back?

Ross

Excellent news Nigel.

I bet you are like a kid at Christmas now.

Fishy whats the news? is it bad?

Sounds like a new ECU is needed, which could be a bugger as new keys may be needed?
Not sure if the fella that owns my ex coop is on here?

This may be a stupid question, but how do gapless rings work? How do you get them on the piston?

Fishydave how the hell have you logged in as me and posted up under my name there?!?

Fishy....the owner of your ex-car is my brother. His forum name is 'intoodeep'

(you can have your thread back now Nigel )

Sean

Thats what worries me, if I ever did sell I think I'd just regret it and want another one and then spend £££'s again getting her the way I want.

Aye, they get into your blood I'm tellin' ye.

Dave - no problem giving you a quick spin in it when its finished and mapped - are you going to be at TOTB?

Dave you shouldnt be able to edit my posts though...

Or is this a mod thing??

Nigels new business venture, test pilots for the space program lol

I would say its very very hard to actually have a 'gapless' ring on a piston unless donw as part of some super advanced machining process...

well its not actually a gapless ring, more a total seal ring

correct - its a pair of rings in the same groove in the piston, but where the two gaps are in different places, giving a gapless effect (and apparently very low oil consumption and an elimination of as much as 95% of blow-by)

How much is it for just the rings alone then or do you have to buy them as part of the kit per say??

Very interesting as it could be usefull for people with just a normal rebuild on the cards as the oil not going out the exhaust will help people more

Fantastic news,.. very exciting Nigel,... any news when you think she'll be ready?

If everything goes to plan (and it currently looks like its going to) the car will be back in my hands on Friday 7th July.

However, it'll be unmapped and in need of running in. I anticipate trying to get 1000 miles on it during the weekend and the following week, ready for an oil and filter change on Saturday 15th July. After that, it'll be another few hundred miles of running in, then a remap. Not sure whether to use PTS for (relative) convenience, or use the opportunity to put another 600 miles on it and travel all the way to Dastek in Edinburgh. Once its mapped, it should be ready for TOTB. Hoping for a reliable 340bhp, with 350 - 360 available if I turn up the boost. I can't see me wanting to run more than 1.5 bar, but if the weather is cool enough, I might chuck some octane booster in and use 1.6bar. I think that Stichl's 397bhp is beyond my reach due to me using the 0.64 turbine housing compared with his 0.86 (although Turbo Dynamics have a feeling that a flowed head through a standard manifold will increase the gas speed to the point where there might be little difference - just got to hope there isn't an issue with back pressure).

The temptation to up the boost and floor it is going to be soooooo hard to resist before I get it mapped.

Nigel if you taking the trip up here (edinburgh way) then give myself and sparco and fergie a shout as we may "join" ya for a few jars to make the trip easier!!!

Ross

Sounds very good indeed, I think you have made a sound choice with the mods
I do think the gt2871r is going to give you a more progressive boost delivery , than say a 0.64 gt28rs. This will enable you to modulate power for the drag strip launch easier (the 0.64 can be like a switch) and then the upper reaches will be very strong when traction should (hopefully) be fine.

It will also be easier on the clutch

Joe

Ooooo!

Pistons are utter works of aluminium art - I almost want to use them as paperweights instead of getting them all dirty and oily.

The head looks like Barbz spent a LONG time on it - I think he licked it clean.

Iceberg has been balancing the rod and piston assemblies.

Clutch looks like it could handle a zillion bhp

I haven't seen the cams, but they're on the bench ready to go in.

And the turbo - its feckin huuuuuuge!

I changed my mind about upping the compression ratio (by skimming the top of the block). I'm pretty sure that I'll be able to get the power I want without risking det. 8.5:1 is plenty high enough anyway.

All that remains is the tantalising two weeks of gentle driving. The car is booked in for a remap (probably including 16VT injectors) at PTS at 9:30am on Saturday 22nd July - anyone that wants to see me wear a groove in their carpet as I pace up and down is welcome to drop in.

I feel like an expectant father outside the delivery room.......

Is today still going to be the big day for collecting it Nigel, I bet you cant wait ?

The hardest part is going to be self restraint and not pressing that accelerator to the floor

Nice one Nigel, what boost are you gonna take this bad boy to... 1.7-1.8bar sounds about right

Iceberg has now realised that its not a normal rebuild, which means it may be late Staurday or early Sunday before I get it back.

Flea - I guess it'll be capable of 1.7 bar without a problem, although part of the idea of the rebuild was to have a monster Coupe at low boost (say 300 bhp @ 1 bar) If I can get 350+ I'll be chuffed, Barbz reckons even higher, but I'll have to wait and see.

I've learned that the pistons and rods have been balanced to a tolerance of 1 gram
