[Mk2] [Turbo] Rev2 at 350bhp?

[mr2nut123]

Recently been out in a 350-360bhp tubby and after getting back in mine, it feels pants so was thinking of saving up to upgrade

The MR2 I went for a spin in, had thousands spent on it and was good for 500bhp so was very unstressed for the parts that were put in there. I was looking at something similar but without spending that much.

What parts would you need to get this power as a daily runner? I was told that I would need forged pistons, rev3 conversion, bearings, commetic HG, modified ct20 or similar, 800cc injectors, power fc and a sard fpr.

The guy really knows his stuff and I trust him fully in the mods he has recommended, I was just wondering what other people thought of these and if they had any other methods of getting this power reliably (other than buying a lambo ) from the 2?

Re-bore
Forged Pistons
Con Rods
ARP Rod bolts
re ground crank
new bearings
steel head gasket
flowed head
Pair of Turbo Cams
Vernier Cam Pulleys
Chargecooler
GT28RS Turbo
Associated fitting paraphernalia for GT28RS
Management - MoTeC, Link, etc
RPS Street Max clutch
Lightweight Fidanza Flywheel
Rev3+ Box with LSD

That should see you a reliable 350bhp all day long.

Who do you think splash We had a quick chat about your car, sounds awesome.

you can't spend 'less' if your looking to forge the engine.
The only difference between 350 and 450 with these builds is the turbo and fuelling. A 350 turbo will still cost you the same as a 450 one. Just more lag.

I personally wouldn't recommend any hybrid turbos if you want to run 350, be it ct26 or ct20b.

You are not going to find a cheap option if you want to run this reliably.

Hi mate, my car is getting mapped to around 350 at the fly soon and i will be running a tdo6, huge charge cooler sard 800 injectors on a power fc with standard internals.

A fair few people are doing the same mate.....mine is a rev3 though so i guess you would need2get a better head gasket as the rev1+2s are pretty pants above 300 bhp.

See, this is the kind of difference in opinion I was on about Some people say that as I have 110k miles on the engine, that anything over 300bhp and my car would need a rebuild soon or blow, some say the complete opposite. Although thinking about it myself, running a huge td06 turbo with just extra cooling surely can't be good for the engine and won't last long unless the engine has been fully rebuilt?

[mr2nut123]

Also, i've been reading up about these power fc units, and as far as I can see, they work fine with the standard rev2 ECU and you can map just about anything you like?

If so, would I simply be able to drop some sard 800cc injectors in (or is this overkill for just 300bhp?), upgrade to a commetic HG and just get it mapped to make use of the extra fueling and injectors? I have been told that the standard fuel pump should be replaced after 300bhp? Would the standard one struggle with 300(ish) bhp?

ok are you just contradicting yourself there, pmsl...
he has a rev3...better pistons, better headgasket, better cams, better inlet manifold than a rev1/2...

id imagine his engine would require less boost than a rev1/2 to hit the same figures....(on top of the massive CC he has)

which ever way you look at it, your going to need a large turbo (not a hybrid), standalone, fuel pump, and larger injectors and mapping.....to just reach those numbers.
let alone maintaining those levels on a stock engine and stock headgasket.

the power FC is a full ecu replacement, so unless you can get hold of a VERY rare AP version, then you will require a full rev3 ecu conversion to run one (like i did)...
it does not work alongside the stock rev2 ecu, it replaces it.
so youd need rewiring of the ecu and various sensors...

[monkeyminger]

for my build i am useing a t34 turbo off a large turbo escort cossie with a adapter (good for 380bhp),haltech ecu 800cc injectors,forged pistons,arp con rod and head bolts.mls head gasket,boot mount intercooler (i think they look good) uprated fuel pump. and a 1 off exhaust.all the rest of the engine is capable of much more so your still in the safty margin.cams are a bit marginal but still should still make the magic 350

I dont post here much,but i think you need to look at fueling.

800cc sard injectors will need a bigger fuel throughput than a standard fuel rail will deliver.

You may find you then need a walbro or similar fuel pump.

Lastly,to regulate increased fuel pressure you may need an adjustable fuel pressure regulator.

just a thought.

I was told by a reputable mr2 tuner (Xxxx) that I would need a walbro fuel pump and a Sard FPR so I don't doubt you would need these for a second

[Driftlimits Performance]

The words Xxxx a reputable don't really mix on here fella

Yeah ok he's done some good stuff. But can any one honestly trust anything he says? Really now?!?

A rev2 rail would like boring out if you're jamming in 800cc IMO.

So what I can gather, hes made a few little fibs about a few timeslips, can we honestly say that we've never spoke pub talk before? As far as modding 2's go he's great! Ive seen some of his work, including the one he's selling at the moment and they're always mega machines and well built.

Bit of a silly thing to say isn't it.
I asume you don't know who nathan at century motorsport is?
Greeny?
Trickster?
Tarmac terroist?

All running 500-800hp!

[mr2nut123]

Sounds like a race to me.

But on a serious note, Xxxx is sound and I bet he's a damn sight cheaper and honest about the parts needed for the power your after..

[Yas]

Maybe not the right way to put it, but I think Tasty is just trying to make a point, not trying to cause beef
