    Luc's SRD1XXX Supra

    The next step for my Supra is a built the engine.

    After having read in several project threads, and after some discussions with Darren, Paul and Ryan, I plan for the following setup.

    - Mahle Pistons (86.5mm)
    - Carillo HD H-Beam rods
    - ACL race bearings
    - SRD Stage 5 race head - the head from Jamie's black Beast
    - Titan main caps
    - L19's exotic
    - ASNU 1100cc injectors
    - Syvecs S6 GP ECU
    - RPS carbon/carbon triple plate clutch
    - Garage Whifbitz coil packs
    - TRD engine mount kit
    - Big case TRD diff with TRD solid mounts
    - SRD 280 cams
    - 4 DP/MP
    - Whifbitz titanium 4" single box exhaust
    - BL366 HF turbo

    I don't plan to upgrade my turbo, as I want something streetable, and no big bhp monster. I would like to see how far the 91-79 tubbie can be pushed, hopefully around 2.2 bar.

    Comments / suggestions are more than welcome, as I want to make my shopping list ready by February, so that long lead time items can be ordered before my trip to Whifbitz (planned somewhere in April).

    Cheers

    Luc

    Hodge made 150 Bhp more on a stock engine.. if you dont want more hp, then it is then really needed to go built engine... Just some food for thought.
    The funniest thing about this particular signature is that by the time you realise it doesn't say anything, it's to late to stop reading it.

    I know what you mean mate.

    I want to do more trackdays in the next years, and therefore, I'm a bit scared that the track will put too much stress on the stock engine.

    Plus, with a proper build engine, there's not much needed for bigger power aims apart from a bigger turbo.

    Thanks for your advice

    Hodge's engine isnt stock. Only the rods are stock iirc.
    Looking for Aftermarket Skirts or Geniuine OEM in 040 white. PM me if you have some. VGC only please.


    Hodge @ Me - You look like Will from The Inbetweeners Dan......brief case ****** !!

    Me @ Hodge - 1.) I dont look like Will. 2.) I'm not posh and 3.) .....well i am a ****** so i'll give you that one, but i still dont look like Will !!

    Sure Hodge has updated ARP rod bolts, main and head bolts, cams and ACL race bearing etc.

    I thought about going this route mate but after chatting will Lee I didn't see the point. I'm planning the same mods as Hodge and running a 7675 through it.

    If your keeping the same turbo just seems a waste especially as you say you don't want big big power.

    Its more to do with the rpm limit imo, stock engine will take the power of a turbo that size at 2.2bar easy if its in good condition and you dont go mad with the rev limit, a big rev limit is very nice to have though and for that reason i would go built engine and flowed head if you can spare the money.

    Also Imo there is no way any of these cars that are quoting hub bhp + 15% are anywhere near the power owners are quoting, hub bhp is nearer to fwhp imo.

    Nice spec. Get a different snail and really push things, help your rev range out alot.

    I have a built bottom end in mine but only because one was offered me at a decent price and has been proven with good power. But i SOOOOOOOO dont need it for my power level target but its nice to have i suppose

    You're right Ricky. The problem is that I always pushed the power more and more. I thought that going once for all for a complete build engine would give me enough growth potential.

    Plus, the stress put on the engine during track days is quite immense.

    I know that the 91-79 tubbie will probably get out of puff above 7.2k.

    The reason for a build engine is mainly for the track use. Plus, if I want to however go for a 76mm tubbie at a later stage, I won't have to upgrade again then.

    What do you mean by "quoting hub bhp"?

    I'm referring to people saying a stock engine is good for xxxbhp when the owner has got that figure by adding 15% to the hub figures they have been given by the dyno (i have been guilty of this myself in the past)

    Quoting hub bhp is the right thing to do imo, adding 15% to the hub figure and calling that your fwhp is miles out, id love to think i have 1330bhp, but i dont.

    Sorry for my lack of knowledge but the results from a hub dyno are measured at the wheels so why would you think that's more the fwhp.

    There will be some losses but may not be 15%. I would think the only way round it would be to go ona hub dymo then straight onto an engine dyno.

    Luc if your are wanting a built engine and you can afford it then fill your boots I will be looking forward to the build thread.

    No mate, they are measured at the hub, the wheels are not even on the car, its not RWHP you get on a hub dyno, its RHHP.

    I dont know the % to use, id guess nearer 5%, Any figure you use other than the figure the dyno gives you is a guess.

    I just thought it was close enough to be the same thing.

    As you say it's virtually impossible to know what % a car has from engine to the hubs.

    Got that Jamie.

    The problem will always be wheelspin on dynos with high hp car though. What I like about the hub dyno is that it gives a very nice indication on the power and torque curves.
