ok i'm going to tear down and rebuild my 97 jdm itr motor before i do my swap here's a list of what i plan to get/do before i put it in:
-have the crank, robs balanced with new balanced and lightened itr pistons
-full blueprinting
-spoon or mugen head gasket
-toda valve springs with portflow retainers
-toda spec b's
-toda cam gears
-power timing belt
-block guard
-mugen oil pan
-spoon thermostat
-water pump
-an-r header
-mugen engine mounts
-toda flywheel & exedy clutch
-some other **** i forgot

anything i'm forgetting, anything that's a waste of time? any suggestions would be appreciated. thanks guys.

Sounds like you're off to a damn good start Sean . The Mugen stuff is money in the toilet though...stock will do just fine.

irunfromcops

think an oem head gasket would be ok with the compression and high revs? i want to make this thing bullet proof before i make it real fast. don't want to have anything to worry about while i'm revving the **** out of it. thanks for your suggestions so far

Well an oem head gasket should lower compression so go with the mugan/spoon, and other than that like said above ditch the useless mugan stuff too much $$$ and not as many gains

How do you consider a mugen oil pan a waste of money? Are you retarded or do just only drive in a straight line?

Jackson

New rod/main bearings and seals.

SOHCrx

Some Bride racing seats and Sabelt 5 point cam-lock racing harness to hold u in your seat because you will haul!!!

Lsos

The thing is as bulletproof as it's going to get right out of the factory. Anything you do is either worse, unnecessary, or stronger but won't last as long, It's designed for sustained revving the **** out of. I don't suggest you lighten the pistons.

Kamin

ive heard the mugen pan can run the pickup dry in hard cornering.
so i would NOT reccomend it for road racing.
wait...maybe thats the moroso pan...
**** i think its the moroso pan...

Jackson

Not the mugen pan. Its just a stock pan with baffles. If anything, it will keep the motor lubricated in turns.

irunfromcops

how about a new oil pump gear like a pro drive or a toda? good insurance or a waste of money? like i said i want to build a fast but bullet proof engine

yea the moroso is the one that's bad for cornering not the mugen.

-Sean

Prod

can't hurt and it's peace of mind...I'd do it

edit : I had the toda cam gears on my old Si...they're nice as hell good choice

ok so it looks like i may forget about the mugen engine mounts, heres the rest of the **** i forgot or added as a result of your suggestions. thanks again guys.

-new main bearings/seals
-AEBS head studs and main bolts
-Hondata intake manifold gasket
-Denso iridium spark plugs
-eventually a full length Fluidyne

and whoever said something about the seats and harnesses, i already have Corbeau Carreras and i'm getting some SRR harnesses to keep me strapped in there

Everything seems good but with the money you are spending you should at least get some forged pistons. If you want to keep the ITR's stock compression you can go for Probe industry pistons. Or get 11.5:1 compression pistons from je, wiseco, arias, and etc. Don't forget new axles, with that much power I'm sure you will break your axles real soon.

Do the block guards help?

Have fun with your build up it should be a blast when its done.

I recommend Honda Saver US4 cams. Beat out JUN III's by 5 whp and 5 ft/lbs of torque. $150 cheaper too.

Forged pistons is precisely one of those things that while it may be much stronger than the factory piece, will not last as long. They are softer and will wear out faster.

Is there really a point to aftermarket rods/ pistons on an N/A setup?

Maximus

Do you have evidence or a test showing that aftermarket forged pistons don't last longer than stock parts? The forged pistons are made of a higher material and also forged at the same time. The quality over the cast alumnium stock pistons is night and day. can you run 20 lbs of boost on stock rods and pistons?

Lsos

No. Before dismissing what I wrote though, do you have evidence that they do?

That's irrelevant. We're talking about an N/A engine.

Cynical 1

I'd also like to know your reasoning on stock pistons being better than forged.

And why are stock the only way to go on a N/A setup? What do you use to raise the CR then?

Tell us why stock are better than forged...

Lsos

IMO stock parts are better than forged, in an N/A setup, because:

They expand less, allowing to run tighter clearances.
They are harder, resulting in less wear.
They are cheaper (I think).

These are all good things which need to be sacrificed when running high boost, as forged pistons are in fact stronger than stock. Hiwever, if you're running an N/A setup, I consider forged pistons a bad design choice.

To raise CR, you swap pistons from cars like the CTR.

vw-honda-hatches

but thats not always possible with cars other than hondas. (VW's etc) Honda was just smart when making there motors, almost everything is interchangeable

Maximus

If forged pistons can run at 20lbs of boost, don't you think they can run 12.1:1 compression at 9000rpm? Ask about forged vs. cast pistons in the tech forum and see what people have to say. I bet they will lean more towards forged than cast.

Lsos

I never said they can't.

Maximus

If they can do that why won't they last longer or perform better than stock in a na motor?

xtrafastcivic

you don't need a block guard(girdle) stock one is fine....
