afternoon gang, since the weather this weekend looks as if it is going to be ok im going to finish off the boot by welding in a new floor and finish the electrics off (95% done), my new Smiths dials came today and look real smart so i shall be fitting them also (shall put a pic of them up later), the hubs are all now 5 stud hubs with v6 calipers and i have also have found the fuel tank which im going to stick in the boot, shall be getting it the end of the month... http://www.proalloy.co.uk/cgi-bin/sh...93&id=proalloy ... after that its just fitting the engine back together and firing her up...

Paul Baldwin · 07-04-2005, 11:36

Great stuff.

How did you get on with the manifolds?

**jamied** · 07-04-2005, 11:41

hummmm...not so much manifold but something that looks like a ride at Alton Towers...

..from rear manifold down..under enging to front of car where it meets the manifold from the front of the car were both go up to the turbo positioned to the right of the front head in front of the gearbox...i shall get some pics of it this weekend when the engine is on the stand and i can fiish it off.

As promised here is a quick pic of the Smiths dials i got this morning and shall be going in the car this weekend with the rest of the electrics. There is a Fuel guage, water temp, oil temp and Turbo pressure. The oil pressure and speedo shall be coming end of month when i order them. Sorry the pics are a bit bad i think i have bust my camera.

CraigG · 07-04-2005, 23:06

hows the engine coming along?

**jamied** · 07-04-2005, 23:12

getting there...checking ways of cooling pistons 5 & 6 due to i have been told that they might overheat, still looking for the pistons but have found that Courtneys sell them off the shelf for £750, Accurite are around £900 but waiting period, but im getting a few feed backs from the usa from companys that can do them for around $500. Bar just a few set-backs its getting there.
just cheacked a thread on here that vauxhall did a prototype engine and might have parts but i had a look on the EPC and found nothing...

astragsi · 08-04-2005, 12:29

coming along very nicely mate. got any pics of the manifolds, engine etc??

on EPC search for C25LET, this is what it was going to be called and started production of the parts i think but it got discontinued.

**jamied** · 08-04-2005, 12:47

i shall have a look when i get home..just want to see if vauxhall do the turbo pistons for them still, and if there a bit cheaper than Courtneys. i shall get a few pics this weekend.

astragsi · 08-04-2005, 12:56

if they still did them i dont think they will be very cheap, also i dont think they will be as strong as the courtney ones considering your going to be running a T3 and nitrous

look forward to the pics

BeArDy · 11-04-2005, 14:58

**jamied** · 15-05-2005, 21:30

Why whats happened!

**jamied** · 15-05-2005, 22:08

finding it a bit hard to get pistons less than £1200. courtneys seem to be the cheapest around but i was thinking..3ltr..LET pistons..bit more power..hummmm...its probaly because i've given myself about 30 electric shocks this weekend finishing the wiring in the car that im looking for easy fittings for now so i can get out to the shows and track days..

**jamied** · 26-05-2005, 20:45

Evening gang, the v6 turbo project has took a bit of a turn with the 2.5 ltr engine....its now a 3 ltr....

...picking up the heads and block with crank tomorrow...and the 2 ltr turbo pistons should fit in like a dream which means with any luck i should fire her up in the next 4-8 weeks..

astragsi · 27-05-2005, 18:37

sweet mate, sounds good to me, get some more pics up when its coming along nicely.

**jamied** · 28-05-2005, 18:33

picked up the v6 3ltr yesterday evening...i got...two 3ltr heads (no cams), 3ltr block, crank, water pump, oil pan and bits, all for £150. stripped it down today to cheak it all over, piston rings were focked and some damage to pistons but everything else was perfect even the cylinder bores. Now the plan will be get some turbo piston from a couple of 2lrt LET's swap the rods from the 2.5ltr over to the 3ltr and get a couple of strong gaskets made for the top end. Also the 3ltr was from a auto, the flywheel was like a piece of paper...why are they so light? Pics will be on here monday night as i forgot the lead for the digi camera....

astragsi · 28-05-2005, 18:43

awaits pics.... 6 LET pistons are going to cost quite a bit tho.

a handful were bunged into calibras apparently, but weren't too reliable..

**jamied** · 30-05-2005, 20:21

**jamied** · 30-05-2005, 21:31

nearly forgot to ask a few techy questions,
when running the turbo what Air Flow Meter should i use?
Can i use the LET turbo flywheel and clutch with the V6 and F28?
And im i two minds on going for a locked transferbox, what power can you shove in to it?

Mark T · 30-05-2005, 23:21

The Auto flywheel is just a starter ring, that's why it's small.

The Turbo, or XE clutch and flywheel will fit, but you need the relevant clutch disc for your chosen gearbox.

the V6 Airflow meters are good for at least 250 BHP, with the standard V6 ECU, although you'll need an ECU capable of controlling Boost.

**jamied** · 31-05-2005, 17:29

i had a look at some of the prices for pistons and found that the Forged pistons for turboed C20XE/C20Let engine in any compressio ratio you want: £270 that Matheus428 is selling on his thread http://www.migweb.co.uk/forums/showthread.php?t=192996 should fit my 3 ltr ok and the price and quality looks good also...he couldn't do the ones for the 2.5 ltr as the cost for a new mould would have pushed them up.
