how relyable is one of these setups?
do you need one of those blow through carby's?
i dont know if this was mentioned but do you need a turbo cam or anything??

lol reading further into this from the other thread you do need a blow through carby.
let us know how ya setups go , as would like to know the relyability of this, ive always herd that carby turbo's are a bit dodgy.

Heres some pics of a Turbo LH that I got from Fullboost. Its not very street friendly with the pipes running under the K-Frame but thats a massive turbo and it runs 9.5 @ 143 which is impressive. Have a look through the Fullboost back catalogue of videos there is a few of this LH running hard. Its a handful to drive when the boost comes on.

all of these drag cars dont have front mounts, this would be much easier to do, than all that screwing arround with a cooler.
is there much performance differance if you dont have a cooler? weekend driving im talking about.

hows is your setup going stock??

the setup is coming along (slowly), i just got my turbo back (gt42). i am still rooting around with the exhaust piping as well but next on teh list is the bottem end, i have a set of chev lj rods resized, a 308 crank cleaned up and resized,and chev forged blower pistons. so i am saving for the machine work now. i will try and get so pics going.

that torana above doesnt really need a IC, I am pretty sure its running on methanol.

what CR are you expecting with that piston/rod combo stock?

Should be around 8.0-8.2:1 there abouts. i think i will be looking at a 75-100 shot of nos to help spool off the line,as it will probabilly be a bit doughy off boost.

If you are running high boos you will need an intercooler unless you are running a really high octane fuel (methanol for example) an IC cools the intake charge allowing you to make more boost/power before detonation occurs.

Pro's:
abillity more power
less chance of detonation

Cons:
costs money (all horsepower costs money)
can be hard to package/ fit in to your car
added piping and coplexity
added weight.

in my opinion, the pro's far outweigh the cons.

there are more types of intercooling than just the front mount air to air IC, you can also have a water to air IC and meth/water injection

hey makka,
sounds good
what do you call high boost?
i can see ya point about it having more pro's than cons. the biggest pro is that bit about not wanting detonation. can be nasty.

yeah rods are 5.7 comp height is 39mm dish is 21cc. just put some photos on, heres the link:- http://wall1096.myph.../view_album.php. the pics of the pistons are of x rods with acl standard pistons and my new set up of LJ chev rods, closed & honed, centres aligned, new 3/8 rod bolts, set up for full floating pins and TRW 4.030 BLOWER PISTONS, double circlips. the collectors are stainless 1.5in 4 into 1. the turbo is a GT42.

LJ SBC Rod 5.700"
308 Rod 5.622"
350 piston pin height 1.560"
308 piston pin height 1.690"

Therefore the SBC combo will sit down the bore 0.052" further than the 308 combo.

Bear in mind that the SBC rod is wider than the 308 rod at the big end. This would require attention before the rods could bolt up to the crank.

If you're trying to display a photo or something, you will need to have it hosted on the internet for others to see it. PM me if you're having trouble with something computer-related.

so what this guy is saying he has 2lb spring in the waste gate what a waste of time for the amount of work thats go into the car.
Makka 8 psi is std boost in alot of cases any more than 12 psi i would think of running an inner cooler or water injection.

waste of time for the amount of work thats go into the car.

If he only ever runs 2psi then there's substancially less wear on the motor, if he wants to keep it nice, tame and reliable then that's the way to go.

And if he wants to whack some full slicks on for the drags or take it to the dyno with a crowd for the weekend, he can put the boost up and appreciate all the work that's gone into the car.

I'm building a bit of a hotty 202 for my LX, that doesn't mean I'm gonna be driving it like a race car just because it has more power than from the factory. It doesn't mean it's a waste of time

Hey Struggler
i just wondering if you would know what rpm and boost the lj rods will stand up to? they have been resized to suit holden crank and for floating pins. havent had them shot peened as some engine builders like to do it and some don't. whats your thoughts?
Thanks
