l20et to l24e turbo

[idolizar]

hey guys i have a L20ET and a l24e, i was wondering if im able to swap my turbo gear straight onto the L24e! and also will my L20et computer run this engine? ur help will be greatly appriciated

Yes it is all a direct bolt on. I think the L24E has a different oil pan though, but you will be swapping that as well if you are converting it to a turbo.

I have done just this type of thing myself a number of years ago. The only difference was that it was onto an L28 instead of an L24.

 

I agree that the sump may be a bit of an issue as it was on my car. I had to drill a hole through the rear dipstick boss on the block and plug up the old one, modify the sump for the turbo oil return and modify the oil pickup too. The rest was a piece of cake really. The L20 turbo should work well with the L24. For an L28, it was too small, but had full boost at a little over 2000 rpm....what a torque monster that was!!.

 

Get a bigger exhaust..I used a 3 incher and that was plenty!

 

Cheers.

He has a HR30 sedan with a stock L20et.

Will be putting in a L24e from an Aussie MR30

 

no drilling etc required, just swap the sumps over, so you have a turbo oil drain and not have to go custom.

the manifolds bolt straight on no problems

just make sure you swap the turbo oil pump in too as the turbo dizzy only connects to the turbo oil shaft

I had the same experience with my L28. .43A/R on the turbine side, you can upgrade to the L28ET housing, the cartridge in the center is exactly the same (if you want to...)

 

I would love to have one of those L20ET Turbos (or a pair of them) back...I sold mine to a guy with an Isuzu 2liter, and wish I had it back for some of my street applications. I loved auto-x'ing that car...invariably instructors would say 'I don't like turbos for auto-x because they have non-linear response' and usually before the first turn it was "this car is

turbocharged? Feels more like a Supercharged car!" Love that early spool, but all-in by 5500. For an L24 it should be very nice.

 

Cheers!

L24e should be the same sump.

 

Just make sure your turbo has the separate elbow from the wastegate housing (280zx turbo style) so you can fabricate a downpipe that will clear the steering shaft.

I have owned and driven small ex housing Z cars, and I gotta say, if you have the displacement, say 3.0 and larger, I would go with the largest turbos possible. That instant response is nice, sorta like an NA HIGH compression car, but it does NOT compare to the extra 200-300 HP you would get out of a large turbo. I autocrossed my tt car, and ridden in Cliftons and ARZ's Turbo cars, which are all 3.0 liters, and they have large turbos, and it works great. They usually turn out some of the fastest street car times there are, and even beat most of the race cars .

 

 

So basicly, I dont think I would ever have a Z car without a fairly large turbo. Instant response is nice, but when you hit 3500 in fourth gear or fith gear, and the 315 wide slicks go all over the place from that much HP, there is no better feeling!

I think it was the RX-7 that used two turbos, a small one for maximum low rpm torque and a bigger one for top end power.

 

Has anyone built an L series like this?

for Australia, a twin turbo setup on a L24e would cost you well over $10,000 easily, as youd need all the supporting groundwork to keep it all together, not to mention heat control issues and boost control, a gearbox that could tackle it, and all sorts of stuff.

in short its not worth it, thw only up-side would be the wank factor

it would be EASIER to get a RB30e and add a $3000 turbo suetup to that, and have fun with 320HP at a third of the price. add a twin cam head to that to make a RB30det for an extra $2000 or so and you could hit the 280kw mark with ease.

 

Stewar Wilkins Racing in Syd has a specialist workshop, classic Z car restorer etc. If you google him you can call him up and ask as many silly questions you want...
