Been on the phone with Chris at ZTech and he has given me a few options, which are as follows.

 

Cheapest option is to go with the 360 thrust bearings or go with the hybrid internals, which is a bit more expensive, or, which i'm really thinking about is, upgrading to the jwt530bb turbos with 5 bolt downpipes and 555 injectors, the thing is, I no someone who is selling the 530 tubs, 555 injectors and the downpipes for £2000 and they've only done around 600 miles, Chris said he would do the work and charge around £1400 labour which includes a service and tests to the engine and a general check of the car.

 

What would you guys and girls suggest, bearing in mind I use the car every day and would like it to be reliable and easy to live with, only looking at around 400bhp for now, I will be changing the intercoolers too and getting remapped, will be upgrading the clutch and flywheel when I have more money is there any thing else I should think about changing?

 

Your advice would be much appreciated.

 

Thanks

Thicker HG would be a good idea if ya running bigger and more boost.

ported polished heads for inreased flow.

I would say you are good with that set up. You are going to need to get your chip remapped though becuase of the bigger injectors. Bare in mind also that you will not be able to run the injectors and turbo's as near to thier full potential as you like until you get some more air into your system and then you will need to look at maybe forged pistons and better cooling.

Doesn't a thicker head gasket kinda counteract the benefits of raised boost ? ;)

 

Anyway, if the engine is out you may as well get the clutch replaced as the mods you're looking at will finish off a standard clutch pretty quickly. You could always get the flywheel skimmed -if it is sufficiently worn.

Sorry didn't read this bit properly. before I replied last.

 

Do you have an aftermarket rad already ?.

 

Also while you are taking the engine out to change the turbo's. It may be worth getting an under plenum bypass done as well as removing and blanking off the EGR.

If your not chasing the big numbers and she's a daily drive, then personally i'd simply have new hybrid tubs fitted, drive in drive out and should be supplied/fitted for just over 2K job done.

Whilst the 2K for the other parts is a bit of a bargain, £1400 for fitting isn't but more importantly you really would have to consider upgrading other parts of the engine at great cost in order to benefit from the new set up.

With labour and parts, you would kick yourself 6 months later when a piston decides to blow or the rings mash, engine out and then another couple of grand.

If you had the cash now to open the block, fit new pistons/rings, slight re-bore and 120k service, then yep buy the JWT530 set up and be very happy, but from my experience, either a set of hybrids fitted and a service OR just buy the JWT's for say around 1200 and around 800 quid for fitting and jobs a goodun ;) you can always upgrade later on anything else.

Already have a koyo rad and electric fan, it has had a bypass done which means nothing to me, could you give me some insight on the benifits of this please?

Thanks for that, I will probably go for the hybrids, what sort of boost can I push safely with the hybrids safely with the mentioned mods?

Yeah but you cant run more boost safely with standard compression and risk blowing the hg, he did mention reliability!!! a slightly thicker hg wont make a noticable difference to bottom end it will also reduce det, but i suppose they are only jwt530's so its not that much more then.

but i suppose they are only jwt530's so its not that much more then.

 

Muhahahha, yea of little faith. They may be small but they blow hard :).

 

They should be capable of running 24 psi with 555's

sarcasm ;)

I think iv'e made up my mind, im gunna go with the hybrids @ 19psi maybe , 555 injectors, upgraded intercoolers, I think that would get me quite reliable power, dont no what sort of hp that would give me though, hopefully over the 400 mark.

Hope your engine is in top form.

lower compression ratio will destroy bottom end..will feel like a micra untill the blades spool up;)

Gunna get it all checked and tested first, hardly ever gets hammered, but I do have my momments, my mate wants to race me in his 2002 m3, dont want to just slightly beet him, I want to thrash him lol

when i said bottom end i meant low down power not the engine crank, bearings etc, and im talking about 0.006 thou thicker not 1mm, its not a shed load. If he wants to run at 20psi on stock compression fine. Let me re phrase myself not only slightly thicker but a stronger cometic gasket. At least he can do this as he's nt rebuilding the internals on the engine.

:slap: i meant power also...any increase in h/g thickness will result in a lower c/r. when we use to race 2 stroke bikes we always left the coke on the piston crowns to decrease the combustion area;)

That would give you more compression, nice:D well some sacrifices have to be made though. If he wants a reliable car as a daily drive then he has to think of the safest way to run bigger turbos at higher boost. While the engine is out its well worth replacing the hg with a new one or potentialy a slightly thicker cometic one or a cometic one at the same thickness bearing in mind how much the head is skimmed.

Oh and why not meth injection too :D wohoooo

ffs :rofl::rofl: thick h/g means head rises off block increasing area to be compressed resulting in a less of a bang known as low compression...you put the same mass of air into an area half the size its more of a bang,whats known as a higher compression ratio.....now go and see iff your pastries are burnt:D;)

 

oh you meant the coke on piston crowns..oops bad me

FFS aaaahhhhhhhhhhh, i was talking about your coke on the piston giving more compression not the thicker hg, COME ON my pastries are just fine thanks.

 

 

Yes you bad mr znut...

Exactly what are the hybrid internals?

My wheels are perfect :D

Im even more confused now on what to do , BAZZ has offered me his engine, which has been rebuilt by chris at ztech and chris is willing to buy my engine, what the hell do I do? Everything on Bazz's engine has been upgraded inc clutch and flywheel, it would cost an absolute fortune to get my engine up to that spec in the future, it works out to be about £1000 more to have the new engine, what to I do?
