Sr24det block with sr16ve head, anyone done it?

[alongso78]

Hi everyone! Newbie here. No one i know in my country has done this. Has anyone here built or saw this kind of engine set up? I have search in this forum but cant found one also. There's alot of Sr24 but i can found one that using Sr16ve head. Hope u guys could give some help, suggestion, idea etc about this set up.

I will using it for drifting on my Silvia 180sx. I hope to get 550-600whp with it. The head, block, air intake, turbo and manifold was already put in together now, just wait for the wiring for the Ecu, injector, fuel pump etc

I want to know the pros and cons with this set up or any details/story about it like it's reliable or not, how high can it rev, how much hp can it get with what turbo etc etc etc. i want as much info i could get about it from this forum. Thanks in advance. I really apriciate it.

This is what i built now. (almost done)
Sr16vvl NEO head
-port and polish
-rebuilt valves and lifters
-custom intake manifold with 75mm throtle body
-reposition solenoid for rwd use

Sr20det block
-2.4 brian crower stroker kit
-BC 4340 billet steel crankshaft (91mm stroke)
-90mm Cp forged piston
-4340 steel billet connecting rods w/ARP fasteners.
-darton sleeve
-line bored and engine balanced
-nismo oil and water pump

I will temporary use a Gt3037 turbo with 45mm Tial wastegate to running in the engine and might swap it to Gt35 .104 with NOS if everythings run well. I got a twin plate Ogura in stock gearbox(know it wont last long). I am using AEM engine management, fuel regulator and fuel rail as well.


The most important things that i would like to know is what is the rev limit for this set up to be efficient and reliable? How much whp can it get? with what turbo etc etc etc. I will post my pic soon. Please give me some input, info or anything regarding to this set up. Thanks!

You'll have to CNC the combustion chamber to 90mm. Mazworx offers that service.

Yes we have done that, actualy Mazworx inspired us to do this. This is our 1st 2.4 bottom block joined with sr16ve, we have built few sr20 and sr22 with this kinda set up before.

Still arguing about it's rev limit, most of us vote not more than 7.5k rpm. A bit low for me...

That's something you'll have to calculate with rod ratio, piston speed, etc. You've bored and stroked the motor, increased rod ratios, added more mass to the pistons, and increased their speed. I don't believe you'll be seeing high rev's with this motor. I'm not an engineer and that's exactly who you need to talk to.

Yes! I believe it wont rev high too but 7500rpm is kinda low, it will have a very short power bend if i put a bigger turbo, a smaller turbo means lower whp. I dont know any engenierrs or experts to do the math. That's why i am here to find the answer from guys that have the experience. Btw thanks jj_ss
