    21 turbo engine into 5 gt turbo

    now please dont jump down my neck on this guys iv done a search and couldnt really find anything on this
    .
    what i want to know is can the 21 turbo engine be put into a 5 gt turbo or even better has it been done, i know the volvo engine is popular and the f7p but this is something id really be interested in as it has 2.0 8v (no replacement for displacement) and t3 turbo 175bhp and 199lb/ft torque as standard ,plus its injection .
    now im not sure on the tuning potential of these but i should imagine its not hard to get them to 250bhp and more torque

    any input would be great on this

    21T engine is longitudinal i think, GTT is transverse.

    Re: 21 turbo engine into 5 gt turbo

    It's been looked into before, and the general consensous was that it would be hard work to make it fit, and be of no real benefit anyway given you could fit a 172/182 engine instead (and therefore have more power straight away), and then turbo that if needs be.

    You would have to cut bulkhead back or extend front end, not worth it for little power gain imo. Also the engine is pretty tall.

    good point but i know the turbo conversion on the 172/182 is not cheap lol plus id imagine a 21 turbo engine as standard vs 172/182 standard in an r5 the 21 would hammer it due to the massive advantage of torque

    Disagree. The 21 engine is more heavier, old technology, and has nowhere near as good a v.e as the 172/182 lumps.

    If you want a 2L turbo'd lump to 'drop in', have a look at Matt C's (Ringworm Tuning) 225t conversion.

    i was also looking into converting mine to injection but the whole kit is around £1300 would you guys like a link to have a look?

    Re: 21 turbo engine into 5 gt turbo

    that looks like a rather mad conversion i bet that goes like mad as well with that much torque coming so low down only having run 14psi as well

    Re: 21 turbo engine into 5 gt turbo

    here is the injection conversion kit for the c1j engine has anyone gone over to this as id like to get away from the carb tuning/probs. also is the claim about there being an instant performance gain by using injection right ?

    heres what it says below

    Airflow surface increased with 64% and as a result a power and torque increase of 20% garanteed at same boost level!
    Due to lower turbo RPM, cooler boost air and as a result more power and drivability

    Is the f4r lighter than the 21t lump? its alloy head/block. Agreed on the 'old technology', the std injection management isnt exaclty tuneable.

    would that be where aftermarket management comes in though? i had an emerald k3 on my old mg zr and that was a cracking ecu

    i take it thats one then id need the universal loom to go with it. is it true then about there being a big advantage and an instant performance gain as the area is greater by 64% and an average of 20% increase at the same boost levels ?
