pickling the brain

[gteben]

Ok in the how to section tells you how to turbo a 1.6. 8v engine.
im looking for a turbo manifold that will fit on to the engine. I know thay courtney did a manifold
But you hardly see them up forsale and ive heard the corsa vxr manifold fits.
would someone know what manifold fits the engine... as I can not seem to get my head around it.
ive never put a turbo on it a engine .tho I did get given a t27 turbo off my great uncle .
also would I be right in thinking where you have the rad you would replace with a duo rad ??

[jimbob-mcgrew]

its probably easiest to use the standard gte manifold, and cut & weld a suitable plate to the bottom of it, to mount the blower. that's the easy bit tho :)

[burgo]

For a start if you are taking advice from someone telling you a corsa vxr turbo will fit then you may as well give up now. And not sure what you mean by a duo rad. Never heard of such a thing

[dgbnova#1]

Someone one here had done similar I know not who but
a VXR will no go on
b modded gte or tube mod to 4-1 manifolds are the only way to go or find one like you said
c internals of engine will need work to lower the compression

dual core radiator was what im meaning. Sorry for spelling errors and no making much sense of it all. Kinda totally lost on the hole turbo idea. Ive heard so many different ways. Im ok at welding panels an such . But ive heard peopke running in to problems making your own manifold
an wouldnt a home made manifold be different to manufactured. Just want as much information as I can get on the idea an what problems along the way I could run into.
I did enail courtney and a few companies an ive had no luck

[jimbob-mcgrew]

a lot of the job will be pretty custom.
when it comes to turbo's, there's pipework all around the engine, so youll have to measure out areas of space and cut pipework to length to suit the bay, then join everything up with silicone elbow hoses.

the fueling and ecu side of it tho, I have no idea whats involved. you might need to run separate management for that ?

also youll need to calculate compression ratio's, to avoid killing the engine. you might need to skim down the piston heads or such work to balance things out. or depending how mad you want to go, all the internals might need strengthening.

theres a lot of work involved turbo'ing a car, and from what ive noticed of other peoples cars, there always getting airleak issues with them, and are forever fixing them.

if you can do it right tho, youll have a quick car on your hands.

[mowgli]

to solve the compression problem, you need to decide if you can afford a standalone ecu or not.. if yes, you can keep the factory compression ratio, if no, then you need at least a spacer.

consider this too, you need to at least fit new piston rings & lap in the valves on an old engine before even thinking about fitting a turbo.

as for the turbo manifold, make up an adaptor out of a block of steel, so it bolts to the manifold & the turbo flanges. its actually the easiest part of the conversion.

[Johnny A]

Depending on how much boost you plan to run will depend on how you go about building. If you're going for 10psi or less there are ways around lowering your compression ratio (thereby leaving the block internals unchanged).

First off I would never turbocharge an engine without going for standalone management - with this level of control over the fuel and ignition you can dial it in to run on high compression.
A decent intercooler is a must and will lower intake temps - this allows the use of higher compressions
A higher octane fuel will allow the use of higher compressions

Combine these 3 things above with low boost and a decent mapper.

Also another alternative is water/methanol injection systems, these are great for lowering intake temps and raising fuel octane (both again allowing the use of higher compressions).

Either way you look at it - if you want to turbocharge an N/A engine and you do it cheap - it will be **** slow and probably blow up. If you spend money it will work BUT bare in mind this is not the best value for money if you want power, fitting a C20LET is still going to yield the best bang for your buck.

[burgo]

At the end of the day its not worth doing. Cheaper and easier to put a redtop in.

[gteben]

How about a z20let engine .am I right by thinking that the hole shell will need welding and strengthing in places to stop it from twisting. Only reason I dont want to go the old red top engine is too many people have done it an want to be different.. I wonder has anyone out there done it.
Also with atleast buying the donor car ill have the break system with it an any bits needed.. the theory behind seems to add up in my head an on paper. But what do you guys think

[burgo]

Yes its been done a number of times before. Anything you do will have been done before

[gteben]

Well thats good news then so atleast there infomation out there to do it. Im also considering the idea of 1300 bike carbs but also looking at a set of throttle bodies. Since as a few of you pointed out the turbo idea with the 1.6 engine is a waste of money. But the way im kinda going with the film the worlds fastest indian. I know on here people are lot more engine minded and im shore on the way of doing it .ill get the advicean knowledge of where not to go wrong. Tho it will be a bumpy ride

[burgo]

So basically you haven't got a clue what you actually as well as not knowing how to do it lol. Not giving us much to go on to help you

[mowgli]

if you want to turbo a 1.6, then do it. if you want to fit a LET, then do it. it is your money & your choice.

I can't recall anyone actually spending proper money on a 1.6 8v to turbo it. its usually done fairly cheaply, with a pikey fuelling method, whereas if one was fully rebuilt, had sufficient mapping for fuel & ignition, with a decent intercooler etc, it would be quite impressive & ought to be able to make 250+hp, maybe more, but as I say, I've never heard of on being done..

if you want to stick a LET in it, then get on to mig sharpish, cos they worship them there

[turbojolt]

Ive read similar things about the corsa vxr mani and turbo but ita ment to be a straight bolt on jobbie for the 16v lumps like the x16xe not the older 8v engines

[turbo-boy]

I have a custom tubular manifold. With a rebuilt Saab t25 turbo with wastegate welded and a external wastegate set up

Pic of it fitted to my Nova

[dgbnova#1]

Now thats how you turbo an 8v lol
is it all up and running now and did you do all the work yourself

[gteben]

Now thats the sort of thing I want to dom set a bike carbs an turbo lol

[gteben]

So would I be right in thinking nova boy with that engine putting a 4speed box the rev range is great each gear then that of a four speed box. Or would it be the other way around. Only reason I get is years ago when I had my old nova friends at that time said to put a four speed box instead of 5speed. Did u make the manifold yourself. Could you possiable send me dimensions of it an what stuff you used..

[burgo]

Your friends are retards! Best box would be an f15.

[gteben]

Can you still buy parts for the f15 gearbox as I would want rebuild since im rebuilding the spare e16se engine

[gteben]

And I almost forgot to ask but with having the f15 gearbox will my drive shafts just slot in or will I need different ends ???

[burgo]

Not worth rebuilding them. Pick them up for £20-£30 at the scrappy all day long and yes your shafts will fit straight in

[gteben]

Oh woonder why there going for silly money on ebay then

[dgbnova#1]

Because people think there worth a lot more than they are 60 is about top price for low miles box

[turbo-boy]

it was my set up i had an omex 600 ecu for it but im putting the car back to standard and have sold a few bits already, there where injection gsxr throttle bodies with a plemum i made for it, was also running a f15 wr box

[_Jake]

Turbo boys manifold is the first proper one ive seen when it comes to turbo 8v's.

You can get a F15 from a corsa sport or gsi but some of them dont have the crown wheel pinion on the shaft unremovable so your stuck with whatever you get.
im gathering bits to do this myself after im bored of my over bored t40 1400. Corsa VXR pistons are a nice design but have a 1mm bigger gudgeon pin so im going to look into having P.E.C make me some rods to take the 1mm bigger pin. What C/R that will give i do not know. so ive got myself a 16xe bottom end and some second hand vxr pistons so my machinist can bore the little end of the x16 rods to take the VXR pistons, so i can sit it in the block and work out my C/R. i have a t25 off a ca18det which should be sufficient for 150hp, using a c14se inlet with c20xe injectors it should be safe.... you seem a bit of a dribbler so i dont expect to see it done properly, all of the ones ive seen done on the internet look shonky in my opinion but i dont class a spacer plate as "proper"

Also in reply to burgos comment on boxes, every box you pick up at a scrappy will have play in the bearings, everyone ive stripped has! im rebuilding a F13 at the moment for mine.

[burgo]

Im sure it will have but for the cost of a recon box you can have about 10 scrappy boxes. The engine will go bang more than the box anyway

[gteben]

Well I purchased a set of r1 bike carbs. Im gonna keep the same gearbox. Going to have it rebuilt instead . Looking in to changing the igintion system to a core pack. The head im going to send it too phil an have the head rebuilt ported an polished. To bottom end of the engine im shore where to go with it. Do I still go down the turbo route or not. Ive had a decent offer for a turbo an manifold

[dgbnova#1]

Send the lot to phil
decide what you want
he will build it to whatever you want
it will come back

simples lol

stick with na engine far cheaper to do and run put ure carbs on and with the full re build engine lots of reliable fun

[bazil]

So me using F28 is a bit of overkill on a 1600 8V turbo then lol

[dgbnova#1]

Thought it was gona be 1.8 lol

[bazil]

The rational side of my brain keeps saying that I should use oversized corsa vxr pistons and forged rods etc
,
The silly side of the brain says " BORING " and bought a Z18XE crank off ebay 2 weeks ago lol

[dgbnova#1]

You and those impulse buys lol

[gteben]

Im gonna send it too phil lol
