Engine Building Help!

[OllieT&E24]

About to be embarking on rebuilding my engine and can't find a great step by step guide on all the tips and tricks when rebuilding a modified engine.

If someone would be willing to give me a run through or a write up on how to do it that would be massively appreciated. I am a mechanic by trade but since I have never ripped into one of these engines specifially, it would be great to know what to do roughly!

I know the basics of rebuilding and engine, just don't know the finiky bits like degree'ing the cams etc to suit how much material is taken off the head etc.

Specs are:

Bottom end:
Block: (Hope all clearances are within spec and give it a quick hone)
Standard Crank (Measure end float and out of round, Get polished)
Bridgeway H Beams,
Weisco Forged pistons with rings and gudgeon pins
ACL main bearings (5-9 Upgraded Thrusts( Standard size))
ACL big end bearings (Standard Size)
ARP Main studs
Ross Sport balance shaft delete kit
New hydraulic tensioner
OEM Oil pump
OEM Gasket Set
Tomei Oil slicer plate

Head:
Kelford 272 Cams,
Piper Cam Pulleys,
Manley springs and retainers with valvelocks
OEM IX MR Headgasket
New Valve stem seals
Kiggly HLA
ARP L19 Head studs

Was also thinking of getting the whole rotating assembly balanced so when its assembled its as balanced as it can be!

Like I said, any help or a write up would be greatly appreciated!

I think the problem you'll find is that the MLR Members who really know how to build/re-build Evo engines aren't likely to divulge their secrets on an open forum.

Very very true!

I don't mind if they wish to jump into contact with me privately!

Start researching ,the info you need is out there

When you say “block - hope all clearances are in spec and give it a quick hone” do you mean you hope they are once checked or you will literally be hoping they are?

Print off the manuals that are on here very useful and will tell you everything you need to know and all the spec and clearances / torque settings

Get the block measured and your pistons if you not confident doing it yourself don't just hope it's ok you will want the correct pistons to wall clearance.

As for balance shaft delete you will have to turn the bearings round so they blank off the oil gallery holes
If you didn't already know that . I prefer to leave them in have had engines with and without balance shaft but it's up to you.

Also when using Wisco pistons just make sure the oil sqirters don't hit the pistons as they will be very close I have had to slightly bent them on both my engine I have built using wiseco pistons

as previously stated... download the manuals. The engine overhaul section has most of what you need.
ACL bearings in std size will probably give you too much clearance out of the box, but that will depend on the crank size you have as not all engines are the same. ACL does provide slightly undersized bearings too..

Have a YouTube search for ‘JRP Performance’ they are a tuning shop in the US and post a lot of videos about engine building tips. Found some of them very interesting

I'll check them all for sure when I strip the block down but for now, until I do, I'm hoping they are all within spec

Yeah, when I rip it all down I'll measure the clearances for the bearings and if they are out, or off I'll have the mains line bored and get oversized ACL's.

I have used ACL bearings and they have alway been in spec be but obviously check Any way

What have you done with your engine? Forged rods and pistons and just check the crank and make sure its all within spec and check the block bores too?

My engine had forged rods and pistons ACL bearings main and head studs
I used a standerd crank just checked it with plastigauge to check clearance and
And used a micromiter to check for out of round . I had my engine re bored and went up to 85.5 mm on the pistons. The manuals on here have every thing you need to know they are very good and worth having when doing a build .

I've watched plenty of his. I also recommend purchasing HPA's online courses. I've got the full wiring course and it is very informative and step by step, I will be purchasing the engine building and calibrating when the time comes.
