it will cost you about 10+ grand, thats just the engine complet with turbo gear

that is built to with stand around 350-450 hp, and hold together

if you dont have that kind of money jap turbo 6 is cheaper way to go!

cheers

i have done it and all i can say is start with a better engine than the holden 6, it doesent lend its self to being turbocharged very well.

sure it can be done but the cost is high and the results wont be as good as you will get with other engines

Mark at EZE-10s performance has a holden 6 running 10s, search him up on the net.

Litre 8 had a turbo 6 as well. Both AFAIK have blown a big hole in the side of the block at some stage.

I would just got Jap or something with a bit more reliability.

Hi
I recon you should not bother with the 202, couse you dont want a V8 id go for a RB30 and turbo that, use VL 5 speed and borg warner diff (Vl Turbo or VN-VS) id would still cost $10000 but i recon it would fly. Try and find a Wrecked VL 5 speed and go from there.

What's the main advantage with that? You get a larger, heavier and uglier motor that costs more to get replacement parts for. It makes running a carbueretter setup (as fat-torrie wishes to do) considerably more difficult, with a custom intake manifold etc.

I can't see why you couldn't get a 202 Turbo setup running cheaply... cheap second hand manifolds and turbo kit (maybe get turbos rebuilt). No blow off valve, no intercooler, no turbo timers or anything, a little bit of piping made up or bought from your local Autobarn. Get an exhaust made up for a few hundred bucks... a standard 202 already has low enough compression to work with. Get a bigger carbie and tune it, electric fuel pump and go driving.

All bolted to an M20, standard tailshaft and Banjo.

I think you're deterring someone un-necessarily. A very cheap turbo six setup can still perform nicely and achieve good fuel efficiency. You don't need a super reliable and expensive setup, at least to start off with.

Sorry if this clutters up your thread Troy.
Heath the way I see it, people are providing the pros the cons and alternatives.

I think a Holden turbo 6 is definitely a fun way to getting more power. Though if Troy did it your way, it would end up being a cheap and nasty set up prone to overheating, not holding boost, cracked 30 year old manifolds.

Nobody likes to spend money...but as Dave is doing now and what Litre 8 did way back...they had to to gain some semblance of reliability. Mark (EZE10s) didn't just put his engine together over night. I'm not saying that Troy's car will be a daily or once a month thrasher...but I'm assuming he wants it to last more than a few drags.

Sure going RB25 or something, you have to factor in the wiring and initial cost but it's a proven 190kw atw with a tune and 10psi (stock motor stock turbo).

back yard 202 turbo setup all the way heaps more fun in my eye's than just putting in a rb30, the fun is in building a 202 turbo set up and testing and what not i reckon......

I never ventilated a block with the turbo 202 but one was starting to part in the lifter galley. Mind you this was after some 22psi and 8000rpm runs so a mild (<=14psi) setup should not have any reliability issues if it is properly prepared (eg blue crank, good rod bolts, head stud kit ).

wow you just encouraged someone to build a crap engine that wont get good performance or good fuel economy!

trust me ive been there

jap is right for a street car its a was of time and money even for a drag car its alot of money to make it hold together ! if you got money to burn like me not! than it dosnt matter what you do with it.its a fun project finding all the right bits but very costly.

japxu1 your flogging a dead horse its like trying to tell people to stop beting money on the dogs ? there is more money in horses.thay just dont listen :ZZZ:

my ones set up using a proform750cfm draw through t04b A/R 0.6 EX A/R 100 strata 5 manifolds,42mm garrett gate will make 400 hp ease ! which is plenty in a lj lc
i have spent up on the cooling side of things. baged the turbo hpc coated the ex manifold.and turbo ex housing.huge alloy radiator billet csr water pump. water/meth 150psi injection kit. 28 row oil cooler.

sorry i was cut short with a call

jap is right a lot of money can be wasted and your not going to get huge hp

my girl friends bro martiy has spent close to 20k on holden 6 turbos only to put a big hole in the block but this was a tunning issue which could of been over looked even with a jap engine it would of done damage !

but that 20 k could of been spent on a jap engine and WAMO ! 1000 HP
he just purchased a rb26 which will make twice the power + the holden made when his finnished building it ,.

Yeah that's exactly how I see it.

wow you just encouraged someone to build a crap engine that wont get good performance or good fuel economy!

Ohh come on stop being so pessimistic. If somebody goes and builds a motor like what I suggested, they might think "ooooh yeah that went well but wasn't too reliable, so I'll re-engineer this section and do this part differently and blah blah blah". Snowball effect plus a few years they might have a consistent sub-10 second car.

Let people start off slow and work their way up into unique turbo setups. Get the passion there, then the skill & experience comes naturally. Besides, you should be promoting this kinda stuff to let it gain popularity. Not discouraging people who are keen to try something different.

The cheapest way as we have talk about before is to use a 186 with hq race 202 pistions
7.2 two 1 comp using a open chamber head! oring the block 12 psi away you go!
300 + hp set up with the right turbo. say a jap import turbo from a ser 3 rx7 home made manifolds carbi or injected blow through or draw through. depending on the turbos compresser seal

Thats what i will be trying after i try the draw through .new roller bearing turbo
custom low mount manifold, cain for barrel intake front mount intercooler water meth injection blowing through the new proform 750 i just purchased .
its not rocket science as another turbo 202 member said... :spit:

just money

dave720gtr you mean blow through. Im with dave 186 with 202 piston thats a cheap way of lowing the comp. Even with a draw through set up with garret manifolds, quadie methonel injection with can run close to 18psi and keep the safe.
I wil post a pic later with this set up.

relying on water/methanol injection is hardly "safe"
a blocked nozzle or empty reservoir will be the end of your engine.

its way too high maintainence/risky for daily driving

i never said i was using mine for a daily driver .and if i was i would wind it back to 10 12 psi were you dont need to have much if any water/ meth spraying in,under or up to 10 psi

I also have a low level indicator warning me if the water level is to low in the holding tank and blocked nozzle alert lights up on the switch panel, this is no back yard water/ meth kit
its the latest gear from the states.

i think this is going to be fun
i will be setting it up on the engine dyno ! so its all tunned right before its fitted to the car. :ZZZ:

i've got a 202 setup, costed me 400 for 12 port head refreshed. 50 bucks for efi manifold, 100 for the pipes for the exhaust manifold. turbo was free. 202 has been worked, but with the 12 port head and difference in chamber size the engine is about 8.8:1 comp and running 7-9 psi thru it will be fine as a daily driver, power will be limited at 150 rwkw / 200rwhp if it hits that mark. this is being used as a daily. if u want a big powerhouse go jap engine with turbo. simple as that.
