Right guys...need some advice/guidance here.

At the moment, i've got an MY98 wagon, with a few small mods.

I've got one of AndyF's TD05/06 20g turbos here, but before fitting, i'd really like think about internals/gaskets etc..as i'm running standard at the moment.

Is there a chosen route ? Any prefered internals ?
I could really do with a pointer in the right direction.

Engine spec at the moment is.

VF30
440's
HKS headers
HKS fmic
H&S d/pipe
H&S 2.5" system and bb.
HKS SSQV
Blitz sus induction
Walbro 255 pump
Helix catch can
All running on Gems ecu at the moment.

Not a wild spec, but i expect with the new turbo, bigger injectors and a fuel reg, it will make a huge difference.

Any help would be appreciated.

Thanks
Johnny.

UK wagon?

Wait till internals go, then uprate them

I think Andy posted up some time ago a link to US where you can buy JE pistons and Eagle rods which are meant to be very good

Claudius

You should get bigger injectors and a remap. If you dont run too much boost you should be fine

Johnny50

Chrome. Yep, UK wagon, sorry i should've said.

Claudius, i expect to be going to 550's or 740's, not decided yet.

Money....pmsl...knowing my luck, everything will go at once !!

Hoppy

If you're going internal, you might fancy a 2.5 unit. See Group Buys - Mark A is getting some more in. He also has a source for uprated pistons and rods. Very helpful guy.

Not that cheap, but very good value (if you get my meaning) with the dollar exchange rate

Hi Richard.
Would love to go down that route, but really cant afford it i'm afraid.

Johnny50

Just found the link matey.

Have emailed them to see what the score is.

Cheers.

Anymore pointers peeps ?

M0NEY

Ive got his email to, just been looking so if they dont reply, ill give you the other email.

Instead of buying the 2.5 and then uprating the internals, will be good as you said just doing the internals on yours. Bullet proof 2.0 would be good fun

All depends on clutch and gearbox then!

What power route you going for? THink 550s will mange 450bhp

Johnny50

Just received an reply email from them.

Aye...cant see my UK box & clutch taking much more..
Not too sure about what power i'm aiming for. (although 400 would be nice)

Really just want some decent power, without the worrys of the engine $hitting it's load.

Johnny50

Anymore help guys ??

Pleeeease.

can i buy some of those 450bhp 550 injectors hhmmmm

Johnny50

Out of interest...what is the max for 550's ?
Wouldn' have thought it was that high surely ??

Claudius

Hahaha


Depends what fuel pressure and duty cycles you are willing to run. A reasonable maximum is about 350 bhp.

================================================== ======

Is this max output at the wheels or at the crank.

Im running currently 365 BHP at the crank with the 440's using a FMIC and walbro fuelpump. According to EMS there's still space on the injectors without an FPR

what's your budget m8?

Johnny50

Dave..not sure, if i knew exactly what was needed, then that would really help.

The other route i'm thinking about is an Sti8 short engine.
At least the internals are a lot stronger in that, than my car.

Does anyone have any experience doing this ?

sti-04!!

Johnny,

Jamie (HI SOOB), recently fitted a STi bottom end to his wrx as the internals went bang on that PM for details as he's probably yer man

you really have to work out what you wanna do and i agree askin questions is the way to go

decide if you wanna go for the i'll make it bullet proof or keep to uprating the main parts(egistons and rods)

cost is at the end of the day one of the biggest questions, so if you had a budget to go by, it might help?

Johnny50

Cost wise i really dont know..If it takes a grand or so then fine.

Bullet proof is what i'm after, but what i dont know is, which is better ?
Putting new pistons/rods in mine, remembering that my motor has done nearly 80k now.
Or buy the short motor, which has done 6k.

If i bought new rods and pistons for mine, is that all i need ?

I've emailed AndyF, to see what he suggests too, cos i really am stuck.

Cheers bud. Will PM him for some info.

john banks

A grand or so will get you nowhere, so tune the engine as though you don't want to break it.

drb5

iTrader: (4)

remember that jamies is a bugeye and his intake manifold will be different so you can't use the same block IIRC.

i very much doubt you'll get uprated rods and pistons and rebuilt for 1k m8. try at least 2k. i would have suggested an sti short block myself, but you'll prolly be looking at about 1.5k for that and then cost of labour to add too it ain't cheap, gotta let you know.

also, while you were doing the rebuild, you'd be as well considering the rest of the bits. for a start you'll need an uprated oil pump-£150 upwards, then full engine gasket set-think it is about £200 and that doesn't include head gaskets, think about upgrading the bearings-think they were about £200 also, maybe crank??, heads, cdb,etc, etc, etc!!!


add's up bud...watcha wanna do then?

Johnny50

I realise it'll be more than a grand, quite prepared to pay more, and i realise i will have to, being realistic.

I do want to fit the TD05/06 that i've got sitting, and want to run it safe.

I'm sure it can be done on my engine the way it is, plenty people have... but i really just wanted to give it that little bit more stabilty and protection. Not out to build a monster or anything.

I can get an Sti8 Short block for a lot less than 1.5k, (not new obviously).

It's either that or keep it as it is... but even then, the mileage is creeping up..

i would do as frank said and run it till it breaks, THEN take it off the road and do it right

Johnny50

Probably easier to justify the costs to the missus if i do that right enough !

Maybe i should buy a Micra...then there'd be no temptation !

Claudius

Hi David

Talking crank bhp. No question you can run leaner AFRs with a FMIC, but 440s and a Walbro sounds a bit tight. What AFRs and inj duty cycles are you running? What gives you the inj duty cycle reading?

David MY99

as far is i know, which isn't that much , the car runs an AFR off 11.5 (0,875 v)? it's mapped with a wideband o2 sensor
EMS talked about injector dutycycle of 18.5 Ms and you can go to 20 Ms?

sorry for the offtopic though

Johnny50

lol.

no worries...it's good just reading all this info...cos i aint got a clue.

Claudius

Not sure which EMS you are running? Duty cycle should stay at 80% max to be safe (manufacturer recommendation), 85% being ok, too, according to what most say. It's theoretically not possible to get enough fuel from 440s to achieve 365 bhp on standard fuel pressure from what I understand. If someone could explain it to me, I'd be very grateful.

18.5 ms sounds very little?

Claudius

OTOH, if an accurate WBo2 tells you it's 11.5:1 AFR, then I guess it is? I'm confused!
