    Its a VNT turbo courtesy of Adam L at turbo developments, top man he is.

    The cozzy fuel rail and pump were lying in a box of bits belonging to the guy who made my inlet manifold, he had to shorten the fuel to suit and adjust the factory pump bracket to fit the cozzy job, so it was easy........... for me anyway, he had no end of trouble with the rail, it kept springing leaks but its been perfect since

    I've heard that, but it should so much easyer to adjust the fueling cus its efi from the factory, what you done to ya C1J lump then?

    Re: Turbo Toaster

    had a vnt turbo from turbo developments on my car for a few track days, until it went pop. need to get it totally re built including turbine shaft and compressor wheel. as stated before the slender shaft isnt exactly robust and dont know if i should bother with it again. like the idea of a seperate waste gate though.

    Have you ever had it dyno'd to see what power its making?

    i think a stage 2 with a bigger turbo elbow, its only slightly bigger than a t2 so maybe better internals, it holds 20 psi well though

    Well I got 150bhp at 17psi with my T2 so I recon you could expect anythin from 160bhp upto 175ish, porviding your setup is good of course

    Re: Turbo Toaster

    i think the only thing stopping it wil be the fueling, i have a uprated fuel pump but i aint sure if the petrol geting to the engine is too little, so might get that looked at so its perfect, but theres no problems so maybe its ok. i once had it boostin 30psi on i race see wot wud happen an it was a rocket haha

    Yeah don't go winding upto 30psi without adjusting the carb or it will go bang.

    When it goes on the dyno make sure the block running the dyno sticks an O2 sensor up ya exhaust and keeps an eye on the fueling

    you dont need forged pistons to run more than 20psi

    He's right, its more important to get your fueling spot on than it is 2 throw money at parts that tunners tell you, you need

    Re: Turbo Toaster

    I'm not sure why people worry about boost, it has no direct relation to how much pressure is in the cylinder. You can have a more powerfull car at only 20psi of boost that has more cylinder pressure.

    Well, no mate, don't believe the hype. There's alot of experience on here all telling you to save your money It's by far much more important to have the car setup properly. A poor tune will melt forged pistons just as quickly as standard ones.

    It'd probably be an idea to see why the turbo blew, rather than jumping onto something else that may well have the same fate...

    the bearing is completely shot and the turbine shaft has big groves were its over heated. The snap ring and sealing ring have melted completely. also the compressor wheel has contacted the housing and is also fecked. the inline filter looks nice and clear but i want to fit another oil pressure guage as the 1 on the car is a bit suspect. I think thats where the problem may lie. another thought is as it went on national day at mallory just after the long sweeping bend oil has moved away from the pickup and the turbo has been starved.
    will have to arrange a day to bring it over to you for a price on its repair

    No it was always at the maximum level but got to be some problem there as you say. As a standard turbo also went pop 3 track days later (although i was pushing it at 17-18psi)

    Defo get a decent oil pressure gauge plumbed in, sounds like your not gettin enough oil pressure

    Has the engine been rebuilt at any point?

    yes it was re built about a year ago but didnt get a new oil pump. droped the sump about a month ago to cure an oil leak and while i was doing it i removed a main cap to check the bearings, as i thought they may be prematurely failing causing a loss of pressure but they are good as new. will fit a new pressure guage next and see what the readings are.

    built the engine myself, apart from having the pistons attached to the con rods by an engineering company (didnt fancy mucking them up)will check the pressure is holding at 45psi as soon as i can get some time on it will try a couple of magnets on the sump too and see what turns up.

    I remember seeing that @ Nat day wasn't a pretty sight seeing that VNT in the condition it was 20 mins later you were back on track running a T2

    Engine update
    Got my spare crank blanaced, reground and some bearings ground to suit, finished painting the block and some of the bits and pieces that bolt to it, so I've started putting it together, gotta get some fresh piston rings then I can finish it and get sorting other things

    Re: Turbo Toaster

    Right, since I started rebuilding my engine I've decided to alter a few bits and do a few things that I have on previous builds, first off I've replaced all the normal bolts that hold all the brackets on the block





    And to go with the new colour scheme I got my spare rocker cover and stripped all the paint off and angle grinded the unused brackets and got going with the red oxide primer


    A quick coat of white primer


    Now I have 1 problem, my original plan was to paint the rocker black with Renault airbrushed in red on the side but now I'm wondering what it'll look like in red all over

    Re: Turbo Toaster

    Update time, first off things have gone a little tits up, namely my pistons aren't exactly round anymore, oh well, good job I've got a new set left from a liner set I bought a year ago.

    Next the rocker cover, I've changed the plan a little, the grouve in the top has now been smooth out and I've stuck on a badge and painted it in, I think I may take it off and get a proper Renault badge though, not sure yet


    To go with the new colour of the block and rocker cover the rest of the ancilieries need attention to fit in with the new scheme, I spotted this ad for sale on ebay from china awhile back but I wasn't sure about the quality cus they were so cheap but a few people on here have bought sets and the've been spot on, as good as the major branded versions so what the hell its only 168quid compared to the 350quid for the branded stuff.

    Overnight parts from Shanghi


    A full set of coolant and breather silicone hoses in lovely black


    And the typical first thing done with new trumpet shaped hoses


    I've also decided to take advantage of the engine being out to replace the old brake master cylinder and brake lines and hoses, a new cyclinder is 40quid from GSF, Lovely , steel braid hoses, 25quid off ebay, sorted, the look on the BMW drivers face when I out brake him, Priceless
