Alright guys, I'm sure this has been covered before, but I just want to get alot of opinions because this is my first high hp build. I was thinking about getting a B20 and sleeving it (stock bore) and running a boosted B20/VTEC setup, but I've been hearing I'm better off with getting a 2.2 stroaker kit & sleeving my C5 and just up the boost? Or even just a 2.0 kit?

Alot of guys are telling me I'd be better off with the stroaked/sleeved C5 because it has oil squirters, and the vtec block's are actually a stronger casting then non-vtec? Doesn't really make sence to me, because I think that if you stroaked a 1.8 out to a 2.2 the sleeves themself's would be thin, and couldn't handle high level's of boost? And a differant casting process sounds a wee bit retarded, but then again I don't know.

What I want to shoot for is low 11's realistically, I'm not going to be over-zealous and say I want 9's. (I DO I DO!) So what kinda hp level's am I going to have to shoot for to get the et in a fulll-wieght ITR. I want to hit 11's with full interior, i don't wanna take anything out of the car, that's part of my goal. I'm thinking somewhere in the 500-550whp range?

If anyone has ran either of these set up's please let me know what you liked and disliked about the set up. All I have ever had was a GSR on 10psi, and my ITR thats runnin 8psi, so this world of over 300whp is new to me. If anyone has any build list's I could possibly check out that would be killer too.

Any help with this build would be great, as this is my first time. So thanks in advance for and help.. I appreciate it..

 

Sleeve the C5 and throw in a simple set of rods and pistons, supporting mods and turbo and you should be good. The best setups in my opinion are the most simple ones.

 

Now another question is when i order my sleeve's, should i order then smaller then my piston O.D. and then machine match (hone) them to my pistons? I've heard about people going with the same size sleeve as thier piston's and getting leaks/blow by.

Think it would be safe to still bore/stroak it to a 2.0L and boost it? The sleeve's wouldn't be too thin would they? (Going for darton mid's)

Thanks for the help though buddy..

 

Sorry for all the question's, but young grasshoppa's have to learn somewhere man..

 

Just send your block away or contact the place that is going to do the work, if they cant answer it, then forget them.

As for your question though, have the motor sleeved and then have a final bore done locally, or send the shop the bottom end and have them assemble it there.

Dont worry about sounding like a noob or whatever, a lot of people will give you **** for questions on here, but they all started there at one point too.

Just remember that <U>the search button here is key</U> for answering a lot of questions that you might have on this site.

 

When it comes to bottom end work, I let Mike at Laskey Racing handle all of it.

Communication is key, just tell them what you are looking to do, and how much power you want to make. They'll chime in and take care of the rest.

Personally, I'm going with a Benson sleeved 83mm GSR with an LS Crank, CP 9:1 and Pauter Rods for my build.

 

Sweet, then I can do my sleeve's and final bore (hone) @ my shop. I work @ Mega Machine's, we do alot of Aero Space parts. Alot of the stuff we do is scaled down prototype's for boeing's wind tunnel. So I'm sure if we can make tail rutters, wing actuator's and other "Aerospace" parts I can have the guy's at work press some sleeve's in for me.

As for the honing we have a Browne & Sharpe honing machine that will hold tolerance's to .00005 so I'm sure I can handle that one. Although I'm not exactly sure how you would do it, I bet I could call a local machine shop that does motor's and ask them.

I'm assuming you would heat up the sleeve's and press them out? And for getting them back in I bet I could dip them in liquid Nitrogen and they would probably slide right in. I'm curious as to how to make sure they are all seated & lined up properly? I can figure it out though.

Thanks for the help though guy's, I really appreciate it. I have a couple more question's though if you dont mind. There just about Turbo's, E.M.S.'s and I/C's.. Here's what I was thinking about..

- T3/T04R or T4/T04R for roughly 500whp on a peak boost ramhorn
or a T3/GT40 or T4/GT40?

-Chrome Pro or Uberdata (which one has more options?)
ie: 2 Step, Boost Settings, Full Throttle Shifts

-Air to Air I/C 24''x12''x3.5'' (Garrett) or a 10'' Liquid to Air w/ 3'' in & out (PWR)

Keep in mind this isn't a everyday car, I hardly drive it and when I do it's mostly @ the track or on a nice day. But I just want low 11's like I said with full wieght. Kinda wondering how much HP I could get on pump gas with this set up too? Let me know what you guys think about the set up's above. Thanks guys!

 

when you say GT40, are you talking about the 40R? That's way too much turbo for 500whp. Find the smallest turbo possible for your absolute highest power goals, then go up just one increment in A/R. (If you can) This will allow you to make the desired power using the fattest powerband, but gives you a little room for power growth in the future.

As for the block..just send it off to someone reputable to sleeve, bore, hone, and install your bottom end for you. It would also be wise to have that same company prep your head.

P.S. You don't need 550whp to do 11's. Something more like 400whp could pull 11's easily. Remember:

Area under the torque curve
Traction
Skill of driver

 

Ohh, ok i was figuring 500 atleast for a full wieght. Only 400whp huh? That's kick ***, make's me a lil' more eager to get my *** out to my garage and start unbolting stuff.

What turbo would you suggest for roughly 500-500whp? GT35? 60-1? I can't say thank's enough for helping me and not just throwin me to the flame, I'm honestly just learning about high hp build's and this forum has been the most help. Alot of people just talk ****, and don't wanna help, but they all built thier first motor once and had to ask questions.

Let me know what you think about the turbo, and maybe the piping itself. I actually have a 2.5'' and 3'' set so, I could use either one. Oh and what about mounting the Tial 50mm BOV by my IC? I've seen guy's do this but I never knew why? Any benifits, or is it just louder or something?

 

1. dont have the wingbats at your work press your sleeves in for you. send it out to a reputable company and have them do it right the first time, worry and hassle free.
2. id prolly buy a b16 or b18c bottom end because its kinda looked down upon to modify the stock type r motor, also that way you can keep your motor in your car.
3. i would go with a gt30r to hit 11's and a good suspension/clutch set up.
4. use 2.5" charge piping and a 3" exhaust
5. id go with hondata or neptune as far as an ems. unless you want to go "all out" and get the aem ems..

 

good stuff so far i have a lot of the same questions as well so your not the only one ill be watching this for sure

 

zeimbo is right. A 30R is a really good choice for 500whp. You'd be maxing out that turbo for sure, and quite honestly it would pull really, really hard since the power curve would be as good as it could get making that kinda power.

I'd buy an LS block. Send it to get sleeved, bored, honed, and I'd supply the parts to the company and have them install everything. Once you get it back...well...you already have a nice head. Just throw some springs, retainers, and a valve job on the already great head and you have a built LSVtec ready to easily make 500whp if you have the right stuff. I would personally go w/ Love Fab's mini me eq manifold for a good spool up, plus lifetime warranty AND it's cheaper than most high end mani's. Use a 30R turbo, .63 hotside preferrably (keep those spool times as low as possible), and 2.5 inch piping (which I think is enough). Hondata all the way. Period. Get some 1000cc injectors though and at least a 255lph fuel pump. Other than the smaller things, which I assume you can figure out, you'd be ready to go. 50mm BOV is fine. Get atleast a 38mm wastegate, maybe even a 44mm if you feel it's necessary.
