Research for my build Sr20det

[R-Yahne_240]

and in reply also this car will be trailered to events and i don't race on the streets the only reason i want it streetable is so i can drive it to a meet and shoot the breeze with the fellows

i know to many people that jack up their cars at the track and don't have a ride home

Here is a very nice car with a 450whp, that I wish I could build.There are some good ideas in that issue of D sport.Seems like you are missing some fuel injectors in your set up. I am guessing 550 cc's and at least a SAFC to keep that monster just a lil bit rich.

[R-Yahne_240]

i have 740cc injectors

also i have a apexi afc neo im not sure the tuning capacity of it but that will not be used on this build

Quick explanation of what Twin Scroll is, Its where the 1+4 Exhaust Runners and 2+3 Exhaust Runners are divided going into the turbo. It creates better exhaust velocity making more torque across the entire rev range. More torque makes for better response and more power. Go GT3071R Twin Scroll if you can afford it. Full Race kit is like 4k i think.

[R-Yahne_240]

yeahhh i did a little research and talked to my buddy shawn with a drag type r civic (sfwd) and he is using a twin scroll set up with a gt42r turbo

he explained how the tq curve is better

i think ill take your advice on that im trying to take my time on this build b/c i dont want to cut corners and money is the key speed factor

i have the money for the block and head now im still looking for the turbo that i want to use

quick diffrences with these turbos

gt3071r and the gt3076r

on http://www.turbobygarrett.com

the 71r shows its a internal wastegate while the 76r is a free float type also top end gains of 50hp+

[redtop91]

Edit: I was wrong.

[R-Yahne_240]

i was checking out the full race set up

any one have personal experiance with that kit GT3071R

anyone

[DrifterProdigy85]

Try Fresh Alloy. There are a few guys there with the GT3071R and GT3076R Twin Scroll Setups. From what ive seen, the GT3071R seems to be awesome. I think Full Race did like 450whp 380tq @ 20psi with one.

[R-Yahne_240]

yeahh i have been up there alot too my terry told me that he saw a sr with 515whp at 22psi on the GT3076R but he was using some wild cams

i was looking at the brian crower stage 3 cams 272 lift do you think that would be to much cam for a "street" car

[Dugi]

I have the BC 264 cams and you don't even know they're there.

[R-Yahne_240]

see i have heard that before so i was thinking about a more aggressive cam but im not sure how "aggressive" the 272s are

some one with experience jump in

thanks

[R-Yahne_240]

Dugi would you mind hittin me up with a list of engine mods that you have running 11s not bad how much boost on you gt2871r????

[DrifterProdigy85]

Stay 264 if your keeping the rev limiter at 7500rpm. Go 272 if your gonna rev over 8000rpm. I had BC 264 cams, honestly i like my HKS 264 cams better. I now have Tomei 270 cams. They can idle rough from time to time. My motor is still new so i havnt driven it into the powerband yet to feel it. I dont expect power to hit hard till 5krpm though.

[DrifterProdigy85]

Also, it takes power and traction to run 11's. 350whp is 116mph trap speeds. Which will run 11's as Dugi did. All it takes is 2871R, 264 Cams, Tubular Exhaust Manifold, Tuning, 550cc Injectors, Z32 MAF for the power.

[guilty_coupe13]

did anybody mention a standlone ECU? i would get a PowerFC or HKS F-Con if i was looking to 350hp+. It comes down to tunning when looking for high hoursepower

[DrifterProdigy85]

I was around 400whp with my Enthalpy Mail Order Tune. Go Standalone if your looking for larger numbers like 450+whp.

[R-Yahne_240]

like i said this build is gonna be done right the rear end set up is going to be a q45 vlsd with axles 5 lug conversion and slicks at the drag track

i was on fresh alloy and there was a right up on that rear end conversion and people were really impressed with it 3.71:1 gear ratio not bad and stout

the swap is simple and you can use junkyard parts

and when your good with the junkyard boys that means cheap or free

[R-Yahne_240]

yeah i was looking at the power fc

anyone with experiance with the Greddy e-manage system!!!!!!

it seems to do about the same but im new into computer tuning

[R-Yahne_240]

Stay 264 if your keeping the rev limiter at 7500rpm. Go 272 if your gonna rev over 8000rpm. I had BC 264 cams, honestly i like my HKS 264 cams better. I now have Tomei 270 cams. They can idle rough from time to time. My motor is still new so i havnt driven it into the powerband yet to feel it. I dont expect power to hit hard till 5krpm though.

let me know how you like your 270s after you lay into her a few good times i really want to rev about 8500 and 270s should look nice with those rpms also help that tq curve

is that your street car??? and whats your limiter

[Hijacker]

This is my personal opinion. If you want to drag, don't use a viscous diff. The viscous fluid will heat up and deteriorate quickly, and then you just have an expensive open diff. For drag, I'd suggest a clutch type, or if you're super poor, a welded diff (I can't believe I just suggested that)

[Dugi]

yeah you can see my modsin my signal below.ems microtech LT-8GT2871R turbo w/ .86 arstock internalsexternal wastegate 38mmhybrd intercooler 24x12x3 core 720cc injectorsFPRand slicksabout 16 psi

that's about it maybe some supporting mods that i forgot to mention but basically just bolt ons

ha ha ha ha i feel you man well its junkyard part and im gonna slip my boy 50 buck to pull all the stuff for me thats all its gonna cost me

[R-Yahne_240]

word i checked out your build and your dyno run on youtube lean it out and let me know what you end up with

[DrifterProdigy85]

Its not my daily driver but is daily drivable. My rev limiter right now is 8500rpm which is just limited by the BC Valve Springs not having enough seat pressure to rev higher safely with the Tomei Solid cams. I run Tomei Solid Lifters too. Wouldnt try to rev over 8krpm without solid lifters.

Drove my SR today for a short time. Layed into it a couple times to see how it spools and when power really comes in. WOT throttle from 3500-5500rpm. Was hitting 14psi in the low 4000rpm area which is normal and could feel the power come on most around 5k-5200rpm. Below that it felt kinda like a teaser. Turbo was spooled but didnt have that kick yet. Only have about 10 miles on the motor so im not about to redline it yet. Also the solid lifters are alot more noticable than stock. Has a fient tap to em which is to be expected. Personally, if your looking for a car to have good response and power, get the largest set of 264 cams you can find. Ive always like HKS and Tomei. Might even want to check out JUN.

[R-Yahne_240]

Bc 264 cams seem like the best bang for the buck compared to the hks 264

my friend has the bc cams and loves them but he has an all-drift setup with the gt2871r

_______still in my neverending mission of research_______

[idahotuner]

i have bc 264 cams to haven't installed them yet. but i am planing on it after i get all my head work done.
