    G'day from Melbourne, Australia.

    I have a Renault Fuego with a 2.2L Turbocharged engine in it.

    I am currently building up a new motor.

    I intended on leaving the bottom end stock, just balanced, as the stock 2.2 rods appear to be pretty sturdy and have the inbuilt oil squirters.

    I am fitting Wossner Forged Pistons (8.0:1) but I have heard of sleeves splitting under high boost on the 2.0. I don't expect the 2.2 to be much different.

    I can't get any high quality liners to suit the longer stroke 2.2 so I had considered getting the liners honed for 88.5mm pistons and then grouting the bottom 20mm of the block to make it one unitary piece. Obviously that means the block is a throw away, but it may solve the problem.

    The car has a large FMIC, 15R Oil cooler and AEM water/meth injection. It's on straight LPG, blowing through a GasResearch Throttle Body (an Australian product)

    This is an old picture below, it's still pretty much the same but the pod filter has now been replaced by an Airbox and Panel Filter with CAI.

    G'day from Brisbane......I'm pretty sure Dave will enlighten you on this as he's building a 2.2 at the min. You have any other pics??

    Yeah, but mostly of the engine bay. The car is due to be repainted soon and it has Clio Sport 280mm front discs and Alloy twin spot calipers from a Ford Falcon AUII. The rear brakes are Laguna 1 discs and Calipers.

    It's lowered a little with rising rate front suspension.

    The rear is lowered a bit with firmer springs. I'm thinking about bolting the rear multi link suspension from a pug 406 (narrowed by 100mm) but I've got a few things I want to try yet with the dead beam.

    It's a bit like a mad science experiment really.

    Liners split from the top, not the bottom....if you envisage going for >250bhp i'd suggest steel liners. Unfortunately the 2.2 liners are longer so 2.0 ones wont work (or the steel rods for that matter).

    I went for a 2.0 not a 2.2 for higher RPM and parts availability reasons. I'm surprised the 2.2 has oil squirters though, I thought that was 2.0Turbo only.

    You've missed the key point, liners don't split from to much boost.
    Water injection/methanol is just a way to get round not being able to adjust timing or increase fuel.
    You don't mention which ecu your using.
    Imo, sell the water injection and add that to what you would spend on steel liners (and anything you'd have to change) and invest in standalone and some good quality mapping with mild boost before cracking it up.

    That's what I'd like to confirm.

    Is it to much boost or is it detonation damage?

    I'd have thought ring lands would fail due to detonation before liners, even forged pistons.

    My car is on straight LPG so the water/meth injection adds some evaporative cooling and allows more boost.

    Yeah I realise they split from the top. But if you can locate and reinforce the liner further up its length, it will improves the strength of the liner. The Honda guys with huge hp drag cars do it to improve strength.

    The 2.2 doesn't have the jets like the turbo, it just has the rod squirters that the 2.0 na don't have (on our cars atleast)

    the 2.0 12v has oil squirters

    to much boost will give detonation if its not remapped

    Yeah, LPG has a higher octane rating and different burn properties and likes more initial advance than petrol at low RPM.

    I'm still running the standard advance curve at the moment and the water injection ramps up from 1psi and is all in at 10psi.

    The car runs 12psi with 9.2:1 compression ratio. Has probably done 40k like that with no problems.

    FWIW, LPG has a much wider safe operating range than petrol too.

    With the new motor I was going to run a Haltech Sprint 500 to control spark and knock control.

    FWIW I'm hoping for 320hp with the new motor at the stock redline.

    FWIW, I've found out that the honda guys who use their cars on the street actually fill their blocks a bit differently to the drag racers.

    The clean the block and liners and fill the bottom cm with block filler. When set, they fill the block with salt, leaving an inch or so free at the top.

    They fill the remaining amount (above the salt) with the block filler to just below the top of the liners and insert some straws through to the salt in the same location as the holes on the head gasket.

    When its dry they flush out the salt with hot water.

    It leaves the top inch and lower half inch of the liner strongly bonded to the block and the other liners.

    I'd think it would be beneficial clamp the liners in place prior to pouring the filler.

    Once its set you can get the liners honed/machined in situ like a one piece block.

    I have a few spare 2.2 blocks and some liners that are scored. I might try it and get the sleevs bored to suit 88.5 pistons.

    Hello From Canada,

    What engine management are you currently running? Also how are you getting throttle response? Are you using a fly by wire setup? I could go on and on about your setup as I also have a 2.2L Fuego.

    One side note. How is it possible you have oil squinter's on the 2.2L?

    The car has a Gas Research 400 CFM mixer. It's basically a carburetor for LPG. It has jets for idle and progression/cruise and a changeable metering rod for larger throttle openings.

    I've managed to get away with the original ignition, but will be running a ecu based system for the new motor. I'm running bp9es plugs.

    I think there might be a break down in translation. The conrods have oil squirters running through them.

    It doesn't have the oil jets like the turbo motor (although it does have the blank bosses cast into the block, so perhaps they could be fitted if you drilled through to the oil circuit and tapped the threads.

    Sorry. I can't edit posts yet. Heres a pick of the Throttle body.[​IMG]

    GT2860RS on 2.2?

    I've been looking around at various new turbo's to suit the Fuego.

    I was thinking about a ball bearing GT2860RS with a T3 housing (they are made to suit Nissan RB series engines and have an open turbine outlet that allows the wastegate to be divorced from the main pipe for better flow.

    The other option is a GT3076 but finding one with a T3 housing with an internal gate is proving difficult.

    Is there a proven 'best solution' for a replacement turbo?

    Do many people run reducer flanges so they can fit turbo's with T28 housings or do you guys fit an external gate to allow more choice?

    the GT28RS or GT2860 turbo is a very good option, will give up to 300-350bhp and can had with a T3 housing, with or without an integral wastegate

    How much difference do these turbos make compared to an old school T3 or T34???
