Very interesting reading....watch this space....

im having my head removed to have the inlet valves changed and refaced. or something like that, at a engine shop, is there anything i should know about setting the timing back up on these? as i think ill probly ask my uncle to do it as he's a mechanic himself, also ill need a new headgasket kit too, anyone know where i can get a good timing belt kit from?

hi guys,

ive recently changed the turbo on my 1.5td corsa to a RHB4 of the 1.7 cav.
ive also increased the fuel and removed the white ring, i also fitted a frontera intercooler and an old N/A inlet manifold.
ive got an air filter straight onto the turbo then through the intercooler to the inlet manifold.
however my problem is ive fitted a bleed valve and im still only getting 0.5bar of boost and wen i come onto boost theres thick white/grey smoke cumming out the back.

basically is it the turbo's nackerd or is sumithing else wrong?

thanks

[tom_moran]

sounds like turbo is shagged mate

[Hacula]

Think the turbo indeed

[reno]

anyone know what size outlets are on the frontera intercooler and what pipe work im going to need to plumb it all into a astra? im thinking 2 90o bends, some straights and 45o?

[reno]

also any links to propane use in TD's?

you need 51mm internal diameter for the outlets

Today I fitted a new (RHF4) turbo and something not good. The car smokes a lot more at the same pressure (max 1bar) and not stronger then before.....And at the same speed the pressure is mutch bigger...ect. 80mhp RHF3 0.3-0.4bar, now RHF4 0.6bar.
Someone help please!

Schaltgetriebe:
F13WR, 3,74
Eco: F13WR, 3,35 (0797* -)

@eggman:
When you undo the clamp, can you rotate the cartridge+compressor freely (i.e. reclock the turbo).
(would be pretty cool, as with the garretts you have to take it apart to reclock it)
The A/R of 13 vs our RHB4's 11 and RHF4's 10 is also a nice step up. (less restriction, and with the vanes still very responsive)

@KertAce:
The 3.35 is nice, but i've only heard of them...never actually seen one !

Nice page.

I tried to rotate the compressor of my RHF5 with the clamp off. Put it in a vice, tried to rotate it with all the power i have, but it didnt give an inch! Any tips on dealing with this without breaking it?

to all those who have fitted the n/a inlet,please can you tell me where you took the vacuum feed for the diesel pump from? and how did you block up the breather pipe found on the front of the inlet? thanks in advance, seb

i pulled the pipe and the metal thing out my TD inlet then drilled a hole in the same place on the N/A inlet and put it and put sum liquid metal around it to make it air tight.

and for the breather pipe i just put a bolt in the pipe and clamped it on

[eggman]

@dutchnovadiesel dont know give me your address and i will post u one for peanuts if u want i also have 2 far bigger T4 sized vv garret blowers


if u want a play with them??

[roperstun]

anyone interested in a frontera intercooler?
im selling mine on, only want wat i paid for it £35

[reno]

Headgaskets are steel layered items, original and aftermarket should be the same (the ones i've seen were all good).
Here's an even cheaper one: http://cgi.ebay.co.uk/ISUZU-GEMINI-1...3A1|240%3A1318

What manifold is on your engine, does it have the plastic filter housing on top or is it all aluminium ?

Here's one from an early corsa, with some modifications: lmao

And what it looked like:


This is the one on later models: (this is from an n/a model, which has a single inlet on the driverside)

To fit this, you need to block the breather connection (see pic), and add the connection for the fuel pump (drill a 4mm hole, and swap or add a connection...just like in the first pic.)

i want to run this inlet as it will be easier to add boost pipes and bigger intercooler.

any more details on what i need to mod to use this inlet on a 1.7TD astra

Use the bottom half of your 1.7TD, so all the vacuumfeeds stay where they are. You have to seal the inlet of the charged air, use a blank plate with a gasket and bolt it on. Then use the upper half of the n/a inlet. This way its easier cuz you dont have to make extra holes and stuff.

i just used that inlet straigh onto my 1.5 blocked the breather hose with a bolt and drilled a small hole in the back for the vacum feed.
im only down the road in newport so if you want to come and have a gander few free

Well i've picked up a new motor today, back in the Isuzu gang.
