just thinking back I also had the pistons quite proud of the deck at least 1 mm and possibly 1.5 mm but the pistons where machined with an angle around the outer edge and the head was set up with the same angle cut where the pistons became close - with the 0.020 copper gasket there was about 0.5 mm ...

if it's any help I used a ridgecrest copper gasket on my astron build a 4G52 - from memory a 0.020 " thick gasket it worked quite well with just a spay of copper coat and some sealer around the oil return

if it;s any help from an old astron punter - I used HPR 40 in my race engines and never had any problems with it an never any unusual wear and unlike a road engine was always running past 7000 in all gears about ever 12 month tear down found the bearings allways still in good nick -- being an oil wi...

BTW5ksev, Incase you thought this, we're not judging you or trying to put you off your plans, It's just an odd conversion (one that I've never heard of), as above -- I have a quite a soft spot for the 4G54 myself Hi everyone, my name is dan and im new to this forum! Sorry but im not a mitsu boy, im...

Stupid computer double posted me

I'd hate to imagine how many people cringe and sigh when they realise its not a 1.6L Toyota engine in the car

I must say I thought it to be a strange choice of engine for the corolla -

The plan so far: A1 Sig block, A2Scorp crank rods and flat-tops, Twin 45 dcoe webers, Crow cam #701 Lift .470", Duration 280deg (212@.050"), 37/63/65/35, lobe separation 104deg (specs on the box) and a head with the usual fruit I wonder what Crow recommend in the way of C/R for that cam -...

Imagine you are going around a right hand corner for example and you have a heavy front sway bar but none on the rear. The front will have very little sway but the rear will have heaps and will want to overtake the front, hence oversteer. No mate if you stiffen up the back with a sway bar you will ...

Hi, does anybody now how much deeper valve cut outs are needed when adding a higher performance cam. (just a guide would be good. ) Just doing a motor and want to allow for developement later on. Motor is a 4g63t sohc 8v. Using Toyota 3sge turbo pistons. Pistons give approx 8.9:1 comp at moments, a...

Starion and jap 5 speed have the same ratios but the staz has taper rollers on the lay shaft and wider gears to handle more torque

try again camber bolts to the lower control arms

Man it sure would be helpful if cheater and stealth would post info on the parts needed to build these set ups for those of us Anyone willing to share their secrets for what 'kits' or pieces you can find online and make these work? I've priced out all the parts around $100 to do it all, but I'd lik...

Cheaterparts....are you planning on getting ur racecar back out onto the track anytime soon???? I keep looking at it -- I have 2 bolts to undo to pull the engine out but have been finding it hard to find the time -- who's slack just wondering I have a Sydney based car on a trailer still in my way t...

how much for these cheater parts? Same price they have been for 5 or more years $ 45 + postage ( and they use to go in a 500 gram express postage bag ) -- they were done as a change over but I will have a few good second hand 4g52/54 spockets that I can drill so theres no need to suppy me with a ge...

just another point I couldn't do coil overs them selfs as the springs and shocks have to be in the std positions for IPRA class

adjustable platforms and shim s are ok as are different weight springs

So all this coilovers talk has got me thinking, what about the rears? All these people going coilovers and I only ever hear about the fronts. Obviously for those with leaf rears it's a bit harder, but Sigma guys what's going on in the rear? Mainly cheater I'm looking good at you, as you also Have a...

http://imageshack.us/a/img391/1853/camgear2.jpg these are the gears I redrill ,( both 4g52/54 and the chain driven 4g32 ) quite a few punters on the site already use them - I still have the specs on autocad and the rotary table is always setup to do this work Belt drive. That's a bloody good idea d...

is it a chain driven cam or a belt

I can redrill the 4G32 chain drive sprocket do give and extra 8 dowel holes 4 advanced and 4 retarded in 1 deg steps

Hi, it is for an EA81 sooby on a gyrocopter.... so it is constantly running at 75%+ throttle, as opposed to hard acceleration followed by idling at the lights and constant throttle changes as in vehicles. Once flying the throttle is basically left at a setting unless climbing or descending.... so f...

Yeah I thought the same cheater......I think the colt has a very similar base to a ford escort (minus the colt following)......they seem to tick all the right boxes for a budget race car with Mitsubishi tending to keep a lot of there bolt up patterns the same ie rear brakes - codia/colt drum backin...

I'm spending next to no cash on this bus as at the end of the day, its still a colt. I must say I have a bit of a soft spot for the humble colt - I was looking for one some years back to build as a race car I always though they would be a pretty good jigger - nice and light with plenty of upgrade g...

there you go a serios bit of gear to fit your colt ---

no worrie if you just widen the whole car by about 120 mm and then it will be tight -- so in a word no it's the same size as any other astron

Both profiles are very different best way is to use a roller cam with roller rocker gear but remove the hydraulic adjusters fit inserts and run Porsche (mahle) lash adjusters just my opinion. Cheers Mic the only thing the Hyd cam wont have quitening ramps like a mechanical cam so there will be more...

sounds more like the cam not run in properly or the oil used didn't contain zink than the double valves springs

But what I'm asking is has anyone tried using the rollers before? And if so did it work? I'm sure someone has actually tried it before. and if it didn't work I'm interested to find out why.

Seeming you guys have touched on the subject of the VW styled tappets, it will be good to get info on using these. First up it looks like they're oil pressurised - do they need to an oil feed to work and if that's the case, how do you do it? I've also seen a few people try using these without succe...

Hey guys, I did want to use the manual adjustment rockers from the Astron 1 but the valves are shorter on the M3 and the angle is all wrong and not much thread left for the lock nut. (probably the reason I didn't use them the last time the engine was overhauled 7 years ago.) there are a couple of o...
