Wats the difference?

[Gt_189]

Hi does n e one wat the difference between the 5EFE nd 5EFHE is? thinking of buildin a 5efte nd have heard tht u use the 5EFE block nd put the head off the 4efte on it? but have heard others talking about using the 5EFHE? any other knowledge on this swap would be apreciated

Cheers

5efe - 9.4:1 compression, same head and cams as 4efte
5efhe - 9.8:1 compression, bigger rods, slightly better cams

Turboing a stock 5e you would be limited to how much boost you could run. Putting 4efte pistons in the 5e would lower the compression and be more boost friendly.

so wats involved in turboing either of these engines? wat would be easier nd cheaper? ive heard i can swap my 4efte head onto a 5efe block making it a 1500 turbo ?
sorry dnt knw much about this jst trying to gather as much info as i can before i try.

cheers

You would be a lot easier to understand if you used English, not text speak.

What do you know about turboing cars?

[Gt_189]

wel i heard tht if u swap the 4efte block for a 5efe one it increases the size of the engine to 1500 turbo. but wanting to no which block u actually use? also wether it will fit str8 back in with out mods?

join starletcentral.co.nz, they got heaps of info on there.

Righto

The difference between a 5efe and a 5efhe: some minor differences in cr (pistons) but primarily in the size of the rods. fhe rods are significantly larger, larger even than the 4efte rods. Thus when building a low compression 5e (5e + 4e pistons) it's preferable to use the fhe bottom end as it's a fair bit stronger. fhe cams are also slightly better than 4e-fte/5e-fe

A fresh 5e-fhe with 4e pistons has been proven to over 200kw at the wheels.

Yes - it will fit back in just fine. Physically the block is about an inch taller (being a stroker motor) than a 4e-fte. Clearance on your exhaust may be a problem, however the last couple of 5e conversions i've seen didn't require any modifications to fit.

The stock 4e-fte ECU will run a 5e-fte hybrid or even unopened motor just fine with the stock CT9 bolted to the side, however not ideal.

Thats not hard, 4EFTE rods are puny. 4K rods are substantially bigger!

Heads are all the same, difference is in length of rod on the 5e.

4efte power steering needs mods to make it fit on 5e. Need to add oil drain to 5e sump or use 4efte sump and oil pickup. 5e has no oil feed for turbo so you gotta think about what your guna do for that. Same with water outlets for turbo, would need to use 4efte housing.

you can tell whos from starlet central on here

I haven't seen 4k's put down 240wkw on a standard bottom end

I've not seen a 4EFE do it either

[loose_unit]

Said 240kw 4e blew up shortly after making that power so doesnt count

no one seems to have said anything about the flywheel issue. you either have to use a 5e flywheel which takes a smaller 200mm clutch. or use a 3et flywheel (rare 2nd hand, but can be brought new) to get the same clutch size as the 4efte one (212mm) or you can go custom of course.

other than that is a better engine than a 4efte as others have said. simple 5efhe with 4efte pistons engine, is good for plenty of power. plus you can afford to go with a big turbo, as they have plenty of power off boost to push a starlet along. another bonus is they are awesome on fuel with the extra compression and not having to be on boost all the time.

please don't put a ct9 on a 5e.

[johndoe1025]

ryans ct9 went fine with a 5efhe?

[QikStarlie]

yeh boring tho, may as well stick with a 4e
