Bigger turbo on way! I hope! lol

[The MoffMeister]

well im lost all i know was that i could buy 20mm pins on new pistons, and they'd still fit in the car as im not increasing displacement, and the money i saved on the valves and rod's i may as well change them to.

Bonus, didnt realise when i was buying the valves that there both inlet and exhaust , bloody wicked, so on to pistons now, i think but still stuck..

O and turbo's only bloody gone and turned up on my door step hasnt it....

double wicked...

would anyone recommend in changing the waistgate to an uprated one ie forge??

why would you want to run a smaller pin?

For his power goals, either size should be okay. Just thinking of his budget.

yep, 350bhp will be fine on the 19mm WP IE rod.

a fair few are using them.

Rob I think the deciding factor for you is the mileage on your car. If it is low mileage I would not bother changing the pistons or rings as they will have very very little wear.

On my 40,000 mile lcr there is virtually no wear on the bores didnt ever have to scrape the wear ridge to get the pistons out! The bores looked in good shape with some slight polishing on of the thrust face but this was expected.

I just changed the big end bearings, rods, circlips and droped the piston asembly back in. DONT CLEAN the bores and remember to stager the rings back up and you should be fine.

if his current pistons are 19mm WP, then i would just throw those rods in if he isnt increasing the displacement.

though as he bought 20mm WP scat rods i was assuming he currently has 20mm wp pistons and advised to keep the stock pistons and run those rods.

like wise if he has 19mm wp pistons

yes but the point it he has scat now, why sell em?

no matter

 

[myk3]

so he can save the money instead of splashing out for pistons, its a bit more hassle but a way of saving a fair bit of money.

i also advised the JE stock pistons from a cheap dealer in the UK if he would like to just go ahead and get some 20mm WP pistons.

myk3, what kind of power you think you'd have if you had new rods and fmic? Would the map be changed a bit?

sorry, bit confused what you are asking, i have had all my internals done.

and i have a eurojet FMIC.

i am in the process of fitting a proper GT2871r turbo, to make around 370bhp which will spool a fair bit quicker than my current eliminator.

 

[PhilW]

Ahhhh, i thought the figures i've seen for your car was on smic and standard internals. WHat did you pull with the eliminator and smic etc..?

 

[The MoffMeister]

so what is my turbo above then, surely GT2871R?? bloody hope so..

Yumann my engine has about 10k or so on the clock so as you say it may be fine, but for peace of mind i will prob get pistons from bill, as i've already had a piston go into my valve wasnt funny i tell ya.. lol mind you warranty is great..

as for the big end bearings are these all standard or can you uprate them to?

Any help on the turbo guys??

LOL 10k your kidding, it hasnt even lossened yet!!! "may be fine" It will be fine mate . If it was me I would not touch them as they will be just coming into there peak now.

Then again new pistons & rings would only need a very light hone easy enough done.

How did your last piston go???

Big end bearings will depend on what rod you use 19mm and 20mm use different bearings.

Yes you can uprate them, I have heavy duty bearings in mine made by glacier expensive but will be worth it in the long run.

There should be a p/n on the metal plate. The go to garret website and cross reference.

cheers yumann, i was at snetterton doing trackday and came round bend on the esse's i think changed down gear whilst car bumping up and down all of a sudden it seems to run on 3, well got it looked at by seat valve had hit a piston so put nice big hole in it and loads of scoring on the block, so complete new engine only 52 plate car i know with a 6 month old engine lol

well i have been offered some 81mm je pistons for £175 which are used but in great nick and i can phone vagtech to confirm, plus there 20mm pin so looks like i'll be sorted, any link to these big ends to yumann

mike my turbo is a gt2871r have checked against garrett website, so what is yours then if its different to mine?


cheers again

No website mate lucky the bearing makers are local to me they can make anything I want or get anything I want as long as I have the p/n. They are the people who supply the so call big bearings bearing manufacturers. Came across the by pure change,

 

[myk3]

moff, sorry mate i thought i refered you too a gt28rs, not that it matters, so we both ahave the same turbo then.

what is the P/N on the metal plate on the CHRA on your turbo just out of interest?

i cant find mine on garretts website what so ever!?

 

[The MoffMeister]

yeah i have found it on there mate, spoke to my mechanic fitting the turbo told him about what you said and he hasnt heard of that before he said its best emailing garrett to find out about that.

mine is 743347-0002

look here http://www.turbobygarrett.com/turbobygarrett/products/catalog.html

and mine was on there so im happy, i was going to do gt28rs but thought against it so in same boat as you, my mechanic reckons i could push 370 or so, come on lol

cheers yumann
