Turbo clevo

[Turbo Clevo]

Just starting to plan to fit a single turbo to a clevo. Just wondering if anyone has done a cheap build up and would like to share some info. I am going to use a suck through set up and a small holset turbo off a CUMMINS diesel engine 6BT. Just gonna throw together a cheapo to fill the void of my N/A engine while I give it a freshen up. ANY HELP WOULD BE APPRECIATED

Thanks

what sort of budjet do u have in mind??

[Turbo Clevo]

No real budget, I am willing to spend as much as it takes to do it properly. Can do most of the work myself, just after photos and advise ect.
Would be good if someone had a kit they were willing to part with???

hi i have a seen it dun before its all welding ,u will have 2 join the enstacters into one pipe and when they join together have a split like 00/00 and then weld a the base plate on top mount your turbo bolt it down . rear ex housing v clap and ex to nthe back ,front comp cover mandral piping 3 inch to throttle..or cardy.

good luck!

Clevo's are reknown for snapping cranks and splitting bores when forced induction is aplyed. You will need a steel crank, decent at leaste shot peaned rods, nascar block with 4 bolt mains not to be confused with just 4 bolt mains as the original nascar blocks have thicker bores and lots of patience. You can run the turbo off 1 bank or two depending on how you want to progress. Hope this has been a help. Anyway check out my web site, i got an VS commodore twin turbos there at http://www.showoffyourwheels.com/MarksTwinturbovs/MarksVStwinturbo.htm

He has spent over 100k to get the car to it's specs. Prolly the easiest ways to get the turbo car street legal is to run gas. Before you start to moan about lpg think of the gains, economy, street legal and easier than having to go nuts with the EPA , RTA and all other relevant authorities. Have seen an xf ute with a clevo 351 twin turbo running straight gas that made aproximately 1500HP on the rear wheels. If you set them up right they go awesome. Hope this has been some help.

hi ive got a single turbo set up for sale for around $2000 if your interested

go speak to georgi haddad if you live in melbourne, he is building a turbo clevo for his XR streeter

Dont need a steel crank or 4 bolts, clevo's are one of the toughest standard engines around. A friend is putting 16 psi from a vortech through his 351C and it is only cast crank and 2 bolts, it is EFI though. has ran 11 flat so far in a full weight XY.

Do it blow through then you can use an intercooler. Easiest way to do it it would be get standard exhaust manifolds and spin them around so they face forward. Only need a carby as well but it's likey you will need to get it modified for boost. Ring Jakes performance in canberra for that. You can get intercoolers off of VPW for just over $200 that will work fine. You'll need a decent fuel pump too like a bosch 600hp efi pump and an aeromotive reg that is designed for an EFI pump use on a carby application.

Alot of what you said is guaranteed to have problems. like the not require steel crank. The cranks on the clevos are not verry strong and on two seperate occasions using forced induction i found the crank split in two in the centre journel. if you are lucky enough to find a clevo two bolt stock with standard bore without much rusty scale on the inside of the jackets you may be right for a short period of time though from experience once you start using forced induction the stock crank and bores say gday.


Might wana rethink the blow through the carbi setup too cause without boxing it off entirely you will leak fuel and gasses into the engine bay from the throttle shafts making for a really good engine fire if something goes wrong. With fabrication you will need to make a box to completely enclose the carby entirely and seal it off from the attmosphere. To save running a riddiculousy overrated fuel pump causing flooding issues run a purge hose to the tank which will equalise the tank and boost pressures allowing you to run a carby fuel pump. Or you can go LPG blow through which will not require pressure feedback into the tank. Gas is nice for this conversion. All i am saying is do it right or you will have to do it again .

Draw through though primitive is an effective and cost effective way to run a twin turbo setup. Though you lack intercoolers there are other methods to keep the intake cool, like water injection, alchohol injection and direct cold air induction. Ultimate would be a custom efi system. Though if you dont have the spare dosh there are a few more options like draw through gas which can also be intercooled as it is a gas.

Clevos are my personal favourite engines, i have had the luck of working for a reputable company building the engines to race specifications and would recomend my advice to all those who will listen to reason. The exhaust manifold idea is old but a cheap way to get the exhaust ducting sorted. SPeak to an engineer before you make the great leap towards the turbo setup.

Any pics of this??

[nickyp00]

Will see what pics i can come up with. was a few years back now and havent had much to do with the guy that owns it since we had a falling out. will see what i can dig out. might have some picks lying round here somewhere.

a mate of mine a stock 3os ran 16.2 put a truck turbo on he bought for $75 turned the exhaust manifolds to mount turbo blow through15 psi ran 12.5 then added 150hp gas and water methanol squirted into turbo and blew the standed gear box hole set up cost $2000

How so?

Clevo cranks are fine for this application, unless massive boost is being forced into it. Maybe the 2 cranks you had let go were not in good shape to start with, i dont know?

What is a rediculously overrated fuel pump?? An N/A carby application requires 7-9psi from the fuel pump to work properly, forcing in boost causes fuel to fight to squirt out the jets, thus requiring a high volume/pressure pump to be used. The only pumps which can do this are EFI pumps like a Bosch 044. Aeromotive are one company that make a regulator which is a rising rate reg alowing you to run a return line to the tank and and a vacuum port so you can add 1psi of fuel pressure for 1psi of boost pressure ie 5psi boost=12-15psi fuel pressure, which stops boost holding fuel in the carb. Good carby builders can modify a carb for blow through easily by using centre hung nitrophyl floats, jet extensions, harder throttle shaft seals to stop the leaking etc etc.

If you go to the length of creating an enclosure then you have to root around with sealing it anyways when you run the throttle cable and fuel lines into it. If a blow through set up just leaks fuel then how come so many people are going with this set up and getting tremendous results?? Have a look at this website www.turbomustangs.com (http://www.turbomustangs.com) and tell me if every one on here has leaky carby's. I'm not getting mean or anything here i'm just trying to get peoples heads around the idea of spending ie $500 bucks on something when they can spend $50.

Straight gas would be the greatest option as there is less paraphenalia required to fuel the engine, 1 supply line, 1 gas throttle body 2 converters and the government will pay for most of it;) Most important is you get to use an intercooler. Draw through gas cant be intercooled it has to be blow through or the intercooler will blow up, gas converters turn the gas back to liquid so that in can be ignited safely, Most important is you get to use an intercooler.

The exhaust idea may be old and cheap but unless your revving the shitter out of you engine there is no need for fancy pants manifolds and the like. @ reversed clevo manifolds will give best results as most people wont really see more than 5500 rpm from there clevo as there is no need.

I aint doubting you but i'd also like to see this XF twin turbo that made 1500rwhp on straight gas?? sounds like a fair bit to me.

TURBO CLEVO if you have no real budget then go the blowthrough. Like i said ring Jakes Performance in Canberra and talk to him about the whole shebang and what you want to do. You already got the turbo so i would say about $3-4 grand should see it setup and running. If anyone doubts me then do so, but i'll prove everything i say when my car cops the treatment.

Here is a simillar one I spotted at the summernats this weekend.
Now what I am sayig to you about the cranks has been with my expereince with things. I have seen split bores in stock clevo blocks once they rev to 7000 and over. Back at FMP it was a regular occurance seiing these things. The owners of these vehicles did use and abuse them though and I mean really abuse them. This occured in a naturally aspirated engined with a solid cam so how can I expect it to last with boost.

The whole idea with running a purge hose to the tank is to equalise the tank pressure with the bowl pressure thereby not requiring a riddiculously overcompensating fuel pump which during regulator malfunction will spew the fuel out everywhere . As for the pics of this XF I am unable to get my hands on as my friend and I had a falling out. These pictures are of a XD with XF gear all over it to make it look like an xf. An efi fuel pump is capable of delivering 40-60 psi on average when a carby should not exceed 6-8 psi or the needle and seat will be overcome and flooding occur. What you are saying is that the fuel pressure regulator will allow the fuel pressure to rise higher than normal to compensate for the booste and stop fuel going back up the venturi and jet of the carburettor. That is not the way a carburettor works though as in theory the process of air rushing past the venturi is what drags the fuel in not the vaccum. So in theory even if you blow into the carburettor provided some of the pressure is fed back to the tank to bring it above atmospheric you should get the same results. If your tank leaks you should look to sort the problem out as tanks should not be vented to the atmosphere as charcoal canisters should be fitted to reduce hydrocarbon emmissions.


The boxing off of a carburettor is a fool proof way of ensuring there is no leakage of fuel out of the throttle shafts and you will find that engineers who are passing the car would prefer this method. Due to modifying the fuel system by introducing a forced induction system you may find the ADR rules may be affected and to get it registered and engineered complications may arise. Depending on year model ADR rating etc. A difference of opinion is a good thing as it allows the readers of this forum to make a informed decision. Think I might have some photos of a clevo crank that split in half at the thrust main journal.

Also might have a pic of the split bore. will have to search my archives.,
The exhaust manifolds turned round are a good diarhea. cheap and do the job. Have seen this method done. Am not sure I agree with the carby mods and the fuel pump though. Would rather run my system with a puge hose to the tank and run a lower pressure pump. The engineer who registers the vehicle would also need to be comfortable with the blowing into the carby. But hey dont mind my trolling, you do make a valid point that people need to rap their heads around the blowing into the carb without boxing it off. Just a bit scary.

Draw through can be intercooled in LPG. To cool it back to a liquid the gas must drop way below atmospheric temperature. Though I wouldnt want a backfire to occur with an intercooler pressursed at 18psi with gas to boot. You will send all your piping and ducting into orbit.
I beleive cheaper is not allways better. You get what you pay for . Build it right and it should go for a while. At the end of the day I love my clevos. They have a few known issues though they are generally a good engine. Built like a brick shithouse.

Dont get me wrong, am not trying to have a go at ya just some of the ideas you are putting forward seem pretty radical and I prefer the security of tried and tested methods than the new. Perhaps you have had good results using your methods and I wish you luck in the future with them. I would personally rather do things slightly differently though with tried and tested methods .

This XD is running two VL turbo's ,Extractors dual GAS research throttle bodies and and twin B1 converters. Ran awesome. seriously good burnouts .

Hi all,
Thanks for the replies. I am right into the project and will post some photos soon. I went the draw through carby way. I just reversed the manifolds and made a mounting flange. It should be running soon.
Done all the work myself ( so its not show quality) but will tidy up ok.
Just running turbo drain and feed lines.

All up cost so far is $280 ( I got the turbo for free).
Will be interesting...........................

what happened with this?

Probably cracked a bore and split the block! Ooh
