Thread: N/A SR20 bolt on setup + (Stock ECU with SAFC?)

^I already have the parts. I knew what I was going to do from the jump. All I need to do is pick up my thermals and look into the Calum some more and I'm set. I think I should be able to make a little more than 160. The guy in post #11 did 160 with that with no cams, .5 less compression, and a 2" header. I know and understand every motor is different, so I'll have to see what happens. Regardless I will have fun with the car. I don't run my car hard a lot anyway. I have to make sure it gets me back and forth to work. Although I would love to have a VE, i'll worry about that later. I don't want to go backwards right now.

Agreed.



If you are trying to squeeze as much as you can out of a DE, a better header will help. I have nothing againt the SSAC, I've had a few, but you could get better.

If you are going with cam gears, I'll assume you have the money for the dyno time to tune them. If the answer is yes, buy the Stg 3's (budget) or C3's (better) with some S&R's.

And lastly, not to hurt your feelings, but if I added correctly, all that money ^^^ already passed a VE with SR16 cams (175+whp)

If he got a VE he would still need header, clutch, fly, pulleys, WS2, Pop charger etc. so those items cancel out.

UK + BC cams = $750 ???

VE + 16VE cams = $1550 ????

I like VEs too but he's on a budget. You can get some loot for the UK cams too. Try selling your 20VE cams

Just be careful with the Cam gears on those flat top pistons. BC cams have more lift iirc.

I disagree, IIRC Dominiken dynoed his VE w/16VE cams and did 170whp on stock manifold and exhaust. Pop charger, pulleys etc are optional for a VE, but necessary for DE making any real power.

But in any case it was just an observation, I think his DE will make good power with the right parts.

^Bowlcut suggested a Gen6 header, but nobody makes them anymore. Then he suggested, the turbofreak header would be the next/best option. Could I use everything from my list except the BC2's and the highport thermal spacers on a VE?

No feelings hurt bro. I'm open to hear opinions, that's why I hit you up with a PM. I decided to leave the following things stock not to go stupid crazy over my budget.

My concern with the BC3's was idle. Not very many people I know of running them N/A and I thought the BC2's would be a better choice for me. I think my compression would need to be higher if I went with those to get the best results.

1.) HIGHPORT 10:1 UKSR20 - $400 - 40k-60k on it supposedly
2.) UR 4 piece pulley set - $200 - brand new (picked up the last set in the nation)
3.) 8lb fidzana flywheel - $115 <---- 1K on it
4.) BC2 cams - $255 - 500 miles
5.) ACT HDSS clutch kit - $395 - brand new
6.) 2.5" SSAC header/flexpipe - $140
7.) Full 2.5" VRS SS exhaust kit - 2.5" x 14" reso - 2.5" cat -$300
8.) Apexi WS2 - $190
9.) Thermal Spacer kit - $123 - brand new
10.) Pop Charger with BOMZ (short ram) eBay piping - $140

^$2258 :TO DATE:


^If I can ever sale the UK auto tranny like I plan, that would knock off on what I paid for the motor.




^What could happen that could tear something up?


P.S. Post #1 was updated with EDIT#5

Nice project
I built something similar about 2 summers ago and have never got round to putting it on the dyno which is crazy. That time is about to come though as it's about to be torn down as i'm emmigrating, so i'll post numbers up soon.


I'm glad you said 'supposedly'. Lowest mileage motor out of the 3cars i've picked up here in the UK was about 80K, and average is well over 100K for an engine that has been out of production for 15years over here. Then again, there's a 1993 P10 Primera across the road from me with a genuine 17K miles on it Been in their family from new, but it's just the GA16DE version.

Regarding all the possible driveability 'issues' listed in post #15, the only problem i have is cold start driving until it's up to operating temp, really nasty, so i just let it idle in the driveway for 5mins
Good luck with the project

UK pistons are flat top no valve reliefs. Cam gears change your valve open and closing events. BC cams are more lift than an S4. You don't want to have pistons meeting valves. I see you took cam gears off the list but I'd still be doing some math if I were you. If you rev over 7500 your valves will be starting to float.



I think that 170whp from a VE with just an intake and 16VE cams is more than you would ordinarily expect. That might not be a good comparison. You do make a fair point. VE needs a switching mechanism $50-100+.

Thanks - Kishada



^I want be reving pass 7500 I usually don't get higher than 7300. My limiter want let me. I thought the S4's had more lift than the BC2's?

S4 Lift Link

BC2 Lift Link

BC2 has more lift but less duration over the S4's

^I just saw that after I double checked.

BC2 lift .475" vs S4 lift 0.464"

BC2 deg.dur. 264 vs S4 deg.dur. 266
