Hey guys, I've just picked a bone stock 2000 si with 70k on it last summer. I'm wanting to boost it and make a 350+whp DD on pump gas. It's gonna be my first build so I have some questions and appreciate any advice given if possible. My budget is $4k and am hoping its enough to be reliable and not blow up or break down after 5k miles.

Anyways, I've been researching a lot and have friends that do a lot with hondas and all that and I've came up with this build.

I'm probably going to leave the engine almost stock if not all stock (which im not so sure about) because I've heard over and over again "it's all in the tune."

So what I am looking into is:
Precision 6262
750cc Injectors
Skunk2 intake mani
Blox Exhaust mai
Walbro
Tial 50mm BOV
Tial 38mm Wastegate
4 bar map sensor
Necessary Oil Lines/Piping
s300
Ebay Intercooler

I know I know "dont get the ebay intercooler!" but it helps my budget and I'm sure it'll just fine, my one buddy who built a 9sec eg had an ebay intercooler, so that convinced me more. I also wanted to get ITR cams but don't know if they're completely necessary, same goes with some arp headstuds. With what I listed up there gives me just enough money for any misc part i need and the tuning + dyno.

I was going to go to Pittsburgh performance to get it tuned (I live in southwestern PA) or possibly try and get out to Evans Tuning.

I know this place is the bible of hondas and I'm new here but I'm sure there are more than a few people who can criticize or give me some advice on this. Thanks in advance.

 

with about 4k I was able to get a decent turbo setup and a built bottom end.

I dont see why your bottom end wouldnt hold up with a nice tune. Just make sure its good to go, compression and leakdown test are the tests to do first before boosting a stock motor.

 

that 6262 while a bad *** drag turbo is a touch big for 350whp which is where your injectors are sized. if you're going for 400+ down the road it would work but for 350whp a 5431b will cost you less and spool quite a bit faster

also, if you want a cheap intercooler mishimoto's are like $120

the s300 is the other place you may save cash. look at crome pro and neptune and ask yourself if the s300 really is that great of a deal

 

you can save some cash getting away from the 6262 and the S300 like racebum said. you could rune neptune and a 60-1.

or you could go with this. im plugging greg bc he is a good guy and i love dealing with him

and dnt cheap out on the 100 bucks for the head studs

2200 and that leaves you 1800 left. so you still have room for a tune and wideband and misc. crap that you may run into

 

Thanks, I'll definitely look into all that.

 

Must have taken a lot of looking around for good prices, unless you did all the install (including internals) yourself.

Pistons, rods, bearings, head studs $1k right there.

 

This is my dyno chart with a 6262 as a DD
My set-up is
stock block
Wiseco 9:0's
Eagle Rods
Precision 6262--Precision Wastegate--Turbosmart BOV--Ebay Intercooler--Ebay pipping
Gsr Head--Type R camshaft
Gt3076 or a T3 .57trim will best suite you if your **** on spool time.. this turbo is always on time in low rpm it's a bit laggy, but I plan on using E85 and sleeving my block..
if you already have the turbo keep it..

 

The 6262 on a stock b16 is going to be very lazy on the street. You should look at getting a simple PTE-5857 so you can utilize the more broad powerband. Alos getting a nice quality turbo kit will save you alot of headaches and be much more user friendly. I bought mine from GO-AUTOWORKS.COM. Greg has VERY affordable turbo kits and his quality is awesome. My car had a stock compression b18c1 in it and it made 400whp @ 16lbs on 93oct using a 5857 journal bearing turbo.

 

ARPS!!! ITR cams would help out alot but u prolly wont need them to reach 350

 

That's a helluva a big turbocharger just for 350whp. whether or not one plans to grow for more power later..

 

I searched around a lot, and got a few stuff used, and Jordan @ Maperformance took care of me on alot of my big stuff

Full Blown Motorsports took care of my block, hot tanked, bored, honed, and assembled all of it and had it done in 2 days for a phenomenal price.

 

All the advice given so far is awesome advice op! What size downpipe and exhaust are you planning to run? Also when you get that down make sure its just straight thru to muffler w/o the cat, and a bung in the dp for the wideband.

 

Oh, BTW. The turbo I recommended to you earlier is the same one a buddy of mine used on his stock b16 bottom end b16 and made 350whp on 12lbs.

 

You and I have the same target goal. I definitely have to agree with racebum, the precision 5431B turbo is good for 480hp at the fly which works out to about 400whp and has a quick spool which is ideal for the street and pretty good if you're going to get in some track time. The 6262 is a much larger turbo with a lot of lag. Save yourself some cash right there.

Forget about the b16 cams with boost. Definitely upgrade those, the ITR cams are a pretty good option. I would say go with Neptune over Crome but the choice is yours. Would also recommend valve springs & retainers. Better to be safe than sorry.

 

For 400whp, there are about 15 different applications that could do the job, really. from Smaller garretts to mid-framed precisions. What are you planning to do with this car? purpose?

 

Billet 5557. If not ITR cams at least some GSR cams.

 

yes a good tune is by far the best... my integra needs a tune and thats pretty much it. i live in mercer county about 1 and a half hour drive north to pitt performance (depending on how fast you go) i have friends that went there nothing but good feedback. and the price is right $300 for if you have 550cc injectors or smaller $325 for 550cc through 1000cc. and thats everything dyno charted and all. i got a completely built head w/ skunk 2 intake, jdm turbo, turbonetics wastegate, greddy bov, and yes a EBAY INNERCOOLER... also have a aem stand alone ems. my car is snappy. id tell you the hp but in not quite sure till i get the dyno done. but its a v8 eater. haha

 

Thanks guys for all the advice. I looked into the 5431b and am pretty sure I am going with that. I mean I do plan down the road upgrading but not a for a long time so I'm pretty set on that one now. Really is a better option haha.

Also, yeah to save some $$$ I think i'm gonna go with the GSR cams if I do come down to buying some and they're virtually the same.

And right right, but I'm planning on 3" since I really don't have any reason not to.

But thanks again for all the info.

 

Oh and I checked out Neptune and Chrome and they're pretty good options and def cheaper so I'm not too too sure right now. I'll probably go with chrome since its cheaper and still gets the job done.

 

The neptune has more hardware/software support than that old Crome mess.

 

Yeah neptune rtp is almost identical to s300. More then capable of handling what you're trying to accomplish. Also Joe at Pittsburgh Performance knows what he is doing. To add...If you're running a blox turbo manifold you need a wastegate elbow with vtec head. Try finding a used inline pro manifold if you can. No fitment issues and it's better.

 

Yeah, my buddy called joe the other day to see about getting his b20vtec retuned, he currently has neptune and was told he only does chrome or s300, so I dont know. And thanks ill look into that

 

Did you check out Go-autoworks.com? I think checking out his pricing and his turbo kits would narrow down some of your ideas as far as an all in one kit.

 

Well my friend with my personal experience I used Crome in the past and Neptune for a while now and I became a dealer too for Neptune. And I can tell you that the difference in those 2 is very big. Software,hardware wise and most important SUPPORT. Neptune has great and fast support. Crome does not have support at all. So definitely go Neptune or go S300 if that is what your local tuner does. don't go Crome.

 

Usually what I do for customers with low budget it get a complete turbo kit with cast iron turbo mani from ebay for 900$. I sell the Ebay turbo back for $200 and you get pretty much everything you need to do a turbo installation. I buy a Garret turbo 60trim/0.63 from VSRACING.NET for around $600 shipped, DSM injectors ( $50-150) on ebay as well , ARP stud kit $140.

That's pretty much it and they do get the 300 hp plus with Bone stock B16. So there are different ways you can go to reach your goal and save some $$$
