ITRCA

Before I post let me say I've spent hours upon hours researching what would be best for me $$ wise and goal-wise.

Goal: Normal driving R with a "little extra" Would like to break 215-220whp... normal idle, nothing insane. Also would like the peace of mind of a fresh block, i'm breaking 135k now.

here's what I'm looking at now

Head
RM M22x
RM Complete Valvetrain
stock IM
possible ported TB

Block
JDM ITR or CTR pistons (would like further advice) .25 over
cylinder wall rehone (obviously)
ARP rod bolts, headstuds
new OEM Rod/Main bearings, Waterpump, Timing Belt, all gaskets, seals and o-rings replaced

Exhaust
Either SMSP or Toda header
would LIKE to keep stock exhaust (i know i know, spending all this money, will it be THAT detrimental?)

Electronics
Chipped P72 or P28 with s200
wideband o2

Fuel
RC 310's (unless you think my stockies will be fine, I think so personally but I always like insight)

Plus I have an Exedy clutch/flywheel i've been waiting to get in anyway


I'm trying to do this within the next 2 months so or so, I already have the shop lined up to do it, they are a weekend warrior outfit in NC but they are Acura master techs in the week, owned many R's.

Essentially with labor/parts I'll be right under the 4k mark, however, I'll sleep knowing I have a fresh, semi-reliable block, plus I want to give it hell at VIR with no worries!


All i'm looking for is some thumbs up or maybe some recommendations on things to do/not to do.

Thanks for your time,
Steve

I'm planning my new ITR build now and have a similar goal.

200 WHP on the stock exhaust. I know for sure the exhaust will have to have the bottlenecks removed.

I'm going with the Mugen intake, SMSP header, SMSP Cat, bored IM, P&P on the head, tappered TB to match IM, hondata IM gasket with coolant bypass and maybe a thinner head gasket.

That should put me pretty damn close to 200 WHP.

stock cams? You should be able to get pretty close i'd think. There's a RM dealer on H-T selling cams/springs/retainers new for 930 shipped.... killer deal, I can't say no to that.

i know it might be a little late but your plans sound good to me their close to mine but look into K Teller for exhaust and header . good luck let me know how the cams are.

Is K Teller loud.... my main goal is to keep it discreet and quiet, I'll sacrifice some WHP not to be a nuisance in my neighborhood.

its nice actually not to loud but still lets people know your their. i also have a cat,res and muffler still. sounds great on the down shift.

Take it from someone that is currently running CTR pistons and do not use them in your build. The dome is ridiculously high, and inefficient. They are prone to detonation and are heavy. It will be most efficient to gain compression with valves, head gasket, etc...

If you want to run a stock exhaust, at least get an electronic cut out so you can free up the flow when the power is needed.

I personally think your WHP goal is a little high. Try adding a Ported IM and a slightly larger TB to the mix if you want better chances.

I recommend the Import Builders intake manifold, I'll be selling mine soon if you have any interest.
