Gt42r Approx Spool Rpm?

[ltd351t]

I'm using the BA 182 n/a engine, not the turbo engine.

If you are thinking that the stock turbo engine is weak, then the n/a one must be even worse, which means I'm in for trouble, lol.

What fails in them? Do the n/a engines have floating pins?

Looks like you more than know enough to do it and make it all work, so good luck and please report back to us as you go along.

You'll find the pistons/rings are pretty good, the rods are the weaker link, and as you would know, its usually the rings and pistons that give up befor rods on turb'd cars so we are lucky there.

Have a look around on fordforums & fordmods as there's a guy there ( and here,Turbotrana ) that put a similar sized tubo on a unopened ED 4.0 motor and had some good results and reports about it, so maybe send him a PM.

With the big frame turbos you dont have the huge heat issues you get with the smaller ( stock sized ) turbo's that we run. Plus you wont have 15psi at 3000 rpm so your rods will be happier.

I for one an very keen to see the outcome.

All of what BCL has said is correct and from his own experiences, and is great info, but your going about this from a different angle with a different aim so your out comes will be alot different.

Oh, its an NA motor... your on your own there lol

PM Dansgli, he knows a bit about turbos on BA NA motors

[ltd351t]

yeah I've read his stuff, it anyone wants to answer these q's feel free.

Do the BA 182 n/a engines use the same piston casting as the turbo engines?

I can mill the tops down easily, but just not sure, my thoughts are that the turbo piston would be a different casting.

Do the BA 182's use floating pins?

[dansedgli]

NA motors dont have floating pins. The turbo motors do.

Chuck the big turbo on there and see how it goes imo.

Lots of people say lots of things but only a few of them have done it. You wont find out how this particular setup goes until you try it. From reading your stuff on fordmods you know what you are on about. Chuck it on there and see how it goes. Motors are cheap so go nuts.

Atomic is making cam gears to overcome the DVCT operation of the motor and give you a verneir type setup. They were due to be released in this month. Not sure if that happened though.

They will help.

[ltd351t]

Damn, I figured as much, any idea about the piston being the same casting? do they use the same size rings and ring pack layout?

Yeah I know many people never actually build anything themselves, plenty of checkbook racers.

Without the VCT system hooked up do they just run at zero? or go nuts?

by the way I agree with what everyone else has said, but your question was without changing the size turbo what can you do, I would say get some second hand turbo pistons, throw them in, make sure you have a very large wastegate to keep the boost down, 3500rpm stall, will stretch to 5200

which is max power, you will not get that off the mark, but you don't need that much anyway,

your rpm range will be, 5400 up to 6000rpm, so you shift as it gets to 6000, and you will be at max power right untill you change at 6000 again, run 3.45 stock gears, you should be right for 125mph

its ok to slip all the way through like that, as long as you have a good trany cooler, (this will be a sh-t box around time, but this is what you have asked, and the power will be good with the big turbo.

but my choice would be to swap it whih some one who wants a dyno car, for a t04z or the like.

that said, I am putting a gt42r on mine, although it will have a 1.05 exh

original Q was more like when will it respond, the rest I can work out as I go, but what you have said sounds good, that will do me.

You sound like you know what your on about, I've pm'd you.

The car will have manualised C4, trans cooling is sorted.

Currently running 3.0 rear but will go 3.25 if I ever race the thing, although I don't see ACT ever building drag strip.

Cheers.

I mean no offence but spare the basics please, I might have low post count but that doesn't make me ignorant.

well you started out asking questions about valve springs being adequate, putting a GT42 WITH 1.15ex, an obvious drag or dyno setup on a street driven, NA BA motor FFS!

surely you can see how rediculous that sounds???

you still havnt told us what car this is going into either...

even if you are a mechanic or fabricator or similar... EVERYONE KNOWS its gonna cost time and money (either or = both the same) surely I could be forgiven for suggesting a hint of ignorance in that regard if you thought otherwise?

The comments I and others have made, were in an effort to save you some time and money, as maybe your outcome could be achieved a better way... so many times you see people waste a stack of cash and every spare minute of thier lives trying to get somthing original to work, then at the end of it to realise it could have been done so much easier a different way.

why dont you come clean and tell us what you do for a living and give us more details about this project of yours?

[ltd351t]

I'm an engineering student, with no job, time is on my side, think of the song, lol.

Previous setup now sold, engine and intake stuff also for sale.

Car as it sits now, awaiting new brackets to be drawn/cut for the control arms, and finish the rear notch, etc, then start on the front which will be cleaner and easier work, looking forward to that.

She will lay rail after that, at least at the rear, front not too sure of just yet, 4" more drop from where the upper ball joint binds is a big ask without drop spindles, but its possible, will probably have a better camber curve afterwards anyway.

Not a mechanic nor a fabricator, just build stuff.
