i am wanting to build my type r. not wanting to make it a full out build just a couple things. i am wanting a skunk2 pro series intake manifold, a 12;1 piston set and cams but im undecided on them and not sure what pistons yet either. wanting to make this a good but cheap build.
after i do all those mods would i need bigger injectors or no?
and what are good but not real expensive pistons and cams?
and open to any other ideas
thanks BIGmike

 

Its a shame you have a type R and have no idea about motors. You could run aftermarket psiton to achieve that compression which would be cheaper to run a slightly thinner head gasket, if you need more compression get the jdm itr pistons they will pump you to 11.1 then thinner headgasket will get you around 11.5( thinner headgasket can give .4 more compression points).

Some used skunk2 cams would be the way to go. Stage 1 or 2, will need new valve springs but resuse your oem retainers. Done all the power you can get for cheap. You could do headgasket, cams, and springs for under 500 in parts if you buy used and search. Once you hit aftermarket pistons you willl jump to over 1300 most likely.

 

the skunk manifold is worthless over the oem p73. either port yours or get the edelbrock performer. piston wise p30s will get you close to 12:1 but it's manditory to be on an aftermarket ecu and you really should have the chambers in the head reshaped to promote swirl. 12:1 with a great tuner is do able on the street but it's hard to run 91 octane in racing conditions with that compression. on a hot day you will have detonation if factory-ish timing maps are used.

 

you know the old adage, fast cheap reliable? well it's true, you can really only have two.

If you are building your motor, it isn't going to be cheap. atleast not if you do it right. Just ripping it apart and throwin some new slugs in and putting it back together will be cheap, the first time. The second time wellllllllllllll not so much.

What are your goals for the car? Let's start there. From what i read now and judging by your lack of current research, it just sounds like you just want to build something for the hell of it.
