vl turbo conversion help needed please!

[buggzy]

has anyone had to drill oil feed lines on a rb30 series 1 block before here?
If so i need to know how far and how wide to drill hole?
I have already drilled about 5 inches and am still to hit oil and im getting worried.
I have looked everywhere on the net and no where tells how far to drill.

any help would be great!
and no i not goign to swap to a series 2 block.

hahaha youve done what? just tee off the oil pressure sender hole and run a hose.

what type of hose? you cant just use rubber hose you know lol.. a braided line that long would cost me about $250 and i already have a oil feed line made ready to go on the bung already there i just gotta drill it till i find oil.

[delcowizzid]

you wont hit oil without the engine running . and im unsure if you can drill to suit

[delcowizzid]

ok after some research you can drill and tap to suit im unsure on how deap but you would want to do this to a stripped engine really and you definatly dont want any metal filings going into the turbo

[Goon]

get a turbo block.. dont use rubber hose.. get a manual or instructions first.. omg..or a firend that done it before to help u..

brains.....brains.. or no brains in here..

i hope you meant 5mm cause 5 inchs your gonna be out the other side of the block soon

i had my series one block drilled a few weeks back

you need to drill 175mm to reach the oil gallerys which are on the other side.
make sure you drill straight as you are drilling between cylinder 3 and 4

make sure you use lube to keep the drill bit cool and keep removing it to get all the drilling swath out.

runn compresed air into the sump to help blow any filings back out so when you break into the gallerys
the hardest part is getting a dril bit that long,
Captian thread had to buy the drill bit which took two weeks to source and was $56 just for that

i had Brenton from Captain thread (in adelaide) do mine and he did top work,
i would highly recomend getting him to do it if your unsure
he charged me $110 to do mine,
i also got the water feed and oil drain done too, ive also had many exhaust manifold studs drilled and tapped

thansk mate thats exactly what i wanted to hear! I will just modify a drill bit now on the lathe thats longer, hardest bit is getting it in there cos there isnt much room!

just watch those metal shavings man ,they can casue some damage!!

yeah thanks its all sorted now, had to drill 165mm into block to find the gallery... you can also blow out the swarf from the otherside using the oil pressure guage hole..
i will drop the oil before we start the car up

[buggzy]

ok got another question... how do you tell the difference between the turbo and non turbo ecu? the ecu I bought in the kit doesnt have any sticker on it, if it did i know it should say 3TM

thanks

[VL_5SPEED]

has it got any stickers? My turbo comp has not 3ta sticker on it, just the "53"sticker on it

[VL Berlina 5speed]

you can take the casing off and there should be a extra brown motherboard or the likes

ill look it to it on CT tonight for you if you want it was posted on there

[nasty1]

you can also run the oil drain back into sump you just have to have it high enough so it can flow

[detox_nath83]

Saves drilling and risking damage with swarf or not drilling straight just use a T-piece on the oil sensor under Plenum as u know that is a pressure point and a nice constant feed of oil.
I get a reading of 60psi on my aftermarket gauge from that point and im gonna use that point when i put my turbo on very soon
Mwahhhhhh

[buggzy]

thanks guys the oil feed and drian are all sorted and turbo and inlet and plumbing is finished, just want to confirm that the ecu i have is infact a turbo ecu? does anyone have photos of this extra board inside the turbo one? it would help lots thanks!

here mate check these pics out
the rb30et has a second board for the knock sensor

rb30e ecu


rb30et ecu

rb30et daughterboard



pics are from ECU - R31info

[buggzy]

thanks for the photos mate, but they didnt help me 100%, the ecu I have looks the same as the NA computer you have shown me there, but it has another board on top of it like the turbo one, but it is only half the size of the knock sensor board show in those photos?it takes up half of the ecu... i might go take a photo to show you all?

[buggzy]

here are some photos of the ecu i have, please can anyone tell me if its turbo or not?

[nasty1]

im sure a auto turbo ecu has 3ta on the casing?

[buggzy]

thanks but how does that help me? did you read the rest of the topic? lol
