@@warrenpeas All holes were in good shape, just making sure there’s no debris inside to ensure equal clamping on all bolts.

@@deepsylol ok. i have 5sfe. i have to change head gasket and im about to pull off the head tomorrow. never done any work on an engine before. i just know to put everythng back on exactly as it came off. i can pull the head off with the intake manifold and fuel rail still on right? i have 91 5sfe from an mr2

@@warrenpeas You should be able to, yes. It’s not a hard job, but you have to work clean and pay attention to details. And don’t forget to use torque wrenches.

It's not the same, but similar. But even the older 5s (91-96) is stronger than 3s block. However, if you plan on going 600whp+ I'd highly advice on getting the 98+ block.

@@deepsylolhow can i know if it is a 98 n up ?

@@caifanesmr2specv The 98+ block has square casting around the water plugs on the block.

Yes, it’s fwd.

His is built and yours is bought

@HolyDriver-lz4jh my k20 is built too 🤭🤷🏾‍♀️ your comment makes no sense, i also had to do the wiring.

I’m using MaxxEcu to control the engine and the transmission. Paddle shifters are connected to the ECU. Forward/reverse is selected from the keyboard which is also connected to the ECU.

​@deepsylol which dq250 did you use bro?

correct

How many teeth timing belt you use ?

@@salimkoodruth4020 I'm using OEM toyota belt with part number 1356879315

@@deepsylol thanks

​@deepsylol I'm late, but did you use a 5sfe head gasket or 3sge gasket?

Car is producing over 780nm at full boost. No problems so far. Car is fwd.

Wow! thanks

Hi, I'm using Garrett gtx3076gen2 with twin-scroll 0.61 AR, I'm getting about a 1:1 map:exhaust map ratio at 1.5 bar of boost. The car got dyno'd for 552whp at 1.9 bars of boost, which is more than I need right now. It has a full boost at 4k. So far I don't plan on going to bigger AR housing

@@deepsylol so you use KURO GTX3076R V-BAND 0.61 A/R TWIN SCROLL ?

i cant find housing for gtx 0.61 TS from garett

Oh wow, I believe you're correct. The weird thing is that 2 years later the engine is still running strong.

You’d probably get worse performance unless you greatly de-shroud them. You don’t gain much area for airflow and most of it hugs the cylinder walls anyway. You’d be best off with de-shrouded stock valves with more lift. Change the springs if you’re changing your powerband location and/or lift. Otherwise stiffer springs when you don’t need them will contribute to more valve train losses and less overall power/efficiency.

Yes, it does. It can be assembled directly with using only stock parts. However, some shops are selling custom headgaskets could improve the cooling flow between head and block as there's minor misalignment.

No 5s-fe has oil squirters as far as I'm aware. We're using oil squirters from BMW M54B30. We've drilled the holes with CNC as the wall of the block there is too thin.

I purchased forged rods for 5sfe that has two slots on both sides that act as oil squirters

Hello, the main reason to use the 5s-fe block is because it has siamese cylinder bores. That means that there are no water passages going between cylinders 2 and 3, which is a well-known weak spot of the 3s-gte block - the block cracks between cylinders. Also, the water pump area is stronger, which allows for higher clamping pressure without cracking the head stud threads near the water pump. 5s-fe has 87mm bore compared to 86mm bore of the 3sgte. Other than that the blocks are identical. You can reuse cranks between the block and pretty much all parts excluding pistons (unless you bore a 3sgte block to 87mm, which is a bad idea).

Can I use stock 5sfe pistons when building my 5sgte?

@@billybrian7181 You can, but it's pointless as they're very weak.

Nice

​@deepsylol you didn't have to shave down your crankshaft?
