Okay guys, I've been doing a ton of research and think I've finally decided on what I want to do for my GSR build! My goal is the infamous 200whp. Do you think this is practicle for this set up? Let me know thanks.

- GSR head and block
- Skunk2 IM
- JG TB (65mm)
- OEM intake with Greddy's yellow filter
- DC header (2") collector << looking into the OEM JDM 4-1 header (2.5") w/ test pipe
- Greddy Evo Exhaust
- Toda Spec Bs
- Omni Power valvetrain
- p30 pistons (standard size)
- VAFC
- chipped p28

 

Not a good choice of header.Even the JDM DC will put some limit on power gains IMO. On my b16 with I/H/E I gained 5hp just going from JDM DC to toda.With my JDM ITR engine it's more like 10hp more. I'd recommend that you save up some $$ and get a toda/smsp/hytech header. Worth the extra money. Rest of the setup looks good although I haven't got any experience with toda cams I've seen some posts about them killing timing belts Could be installation problems or something else though..Just check the belt often and then it shouldn't be a problem

 

Your totally right about the header. It was on there when I bought it and never really changed it out. I'll look into a Toda header.

I had Toda Spec Bs on my old 99 Si and never really had problems with the timing belt. I was using a Toda timing belt though. Honestly, that's the first time I've heard of that problem. Good input though thank you. I will definately look into those other headers.

 

I would suggest you go oversize pistons. I was planning to go standard, but did not want to risk the rings to smoke. The standard size wont fit correctly as opposed to a freshly bored and honed block.

 

^ I would say that unless he has alot of miles on the block (100,000 up) that he should stay standard size. Good little setup though, hopefully you see 200hp (head work will get you alot closer) but if you dont, 180hp is bad either

unfortunately I have 117k on the block. I've rethought my setup and now want to purchase a full GSR block, and have it built by exospeed

 

Maybe 180whp, I have more then that done to me b18c and I'm not even pushing 200whp.

 

117,000 has nothing to do with anything really. I would:

-Disassemble the block
-Hone and hot tank
-Poilsh crank
-Balance the rotating assembly
-Press new P30 pistons to rods
-Install new OEM or NPR rings
-Install new OEM or ACL bearings
-Install new ARP rod bolts
-Install new bottom end gasket kit
-Finish all assembly and blueprinting
-Install new OEM ITR oil pump
-Install new OEM ITR water pump
-Install new OEM ITR timing belt kit with tensioner

There is no reason to rebuy another GSR block in my opinion. Yours just needs to be completly rebuilt. As I said before, good luck with your build, hope this helped some.

 

I totally agree with you, it needs rebuilt. The thing is this is my only car and I'm trying to save on down time. I want to buy a used head and block...get them totally rebuilt, mat together and then over a free weekend, pull my old motor and put the new one in.

 

ahhh. I see. Makes sense now. I considered doing the same thing about a year agon when I was doing my swap. When work schedules get hectic, you cant really afford the downtime..

 

That will definately help keep downtime, but your cam/piston/etc choice seem a little off.

Toda B's suck. Try Jun III, BC4, Skunk Stage2
Why b16 pistons? Try CTR

I used to have a GSR Motor. CTR Pistons, Jun III's, Skunk Manifold, 65mm TB, JDM DC Header, Hondata S100. Made 204 with no cam tuning, and barely any dyno time. Ran on 93 all day with no problems.

Also if your starting with another block, might as well sleeve it.. Rods and pistons cost the same for 800bux your now working with a 2.0L motor which will make alot more power.

Also that greddy evo is very restictive, you might want to look into a 2.5" exhaust that is less restictive.

i'm getting married in FEB 06, not much money to spend on this. also I've been told its a 2.5" exhaust

 

Wow... I'm actually a fan of Toda B's and according to the specs and dyno's they definatly dont "suck" although you might of had better luck with Jun III's which are great cams as well. If I we're to personally choose a cam for this setup though

Rocket Motorsports M22
Dynamic Autosport Spec A

only two I would even consider.

As for the P30's, your on the right track. P30's are not only 1oz per piston lighter than CTR's but also promote better chamber flow and more even combustion. You can always get your compression else where if you want more but mid 11's is perfect for pump gas. Oh yeah, congrats on the soon to come married life

I put down 180whp with Skunk stage ones, no tunning and a stock airbox. I certainly hope he can surpass those numbers.

Yeah I think he will. I pulled 177whp / 121wtq on a stock block GSR, blox type A cams, manifold, and boltons.
