Hey guys havent been on in a while.. used to be under different user name but cant remember my password and dont use that email address any more so i had to make a new one..

anyways im building a new engine in my S13 here are the specs

02 S15 SR20DE Vct
Haltech E8 and all leads and sensors
Acl Thrust washer set
Acl Race series Big end bearings
Acl Race series Main bearings
ARP Head stud Kit
ARP Main Stud Kit
Cometic MLS Head Gasket
Tomei Rocker Arm Stoppers
Eagle 3D H-Beam Forged rods
CP Forged Pistons
Power Max Water Pump
ACL Race Series Gasket Set
Full Machining
Tomei Solid Pivot Kit
Tomei Sr20 Type A Valve Springs
SR20 Camshaft Procam Exhast 270-12.50 solid
Sr20 Camshaft Procam Inlet 270-12.5
Tomei Solid Pivot test shim
Mild Porting
Adjustable Cam Gear
Turbo Injectors
Bosch Fuel Pump

and im considering Quad throttle body

but thats the specs so far.. i have recieved the engine and most of the parts i just cant wait to finish the job.. as im under the P plate restrictions for another year im building a NA engine but once i get off my P's i will change some parts that affect compression ratios and install a turbo

Any Comments

Edit: quite a few new things aswell.. will go in to more detail shortly

Thanks Guys

Scotty

I would suggest you go larger in the cams duration,drop the haltech for a power fc or daughterboard,and definitely go for the quad throttles - at least 48mm if not larger. if that's not possible,use an 80mm single.

go bigger injectors if you're gonna be boosting eventually too.. esp if you're getting a power fc (etc) that is easy to change the parameters

whats the difference between the Haltech E8 and the Power FC?

do a search first. it's been covered several times.


in brief,besides plugging straight in,it has several handy tuning options that you're going to need that a haltech won't,and does a better job of managing the tune.

The place im getting to build the engine specilises in Haltech products and there going to dyno tune it... im going to chat to them bout the power Fc thou thanks mate

Scotty

your making a hive for 300 Killer wasps!!!
your nuts

the haltech will be a better computer to use, more parameters etc, once it's wired up, the PowerFC is only good because it's a bolt in and easy to tune item, but it's missing some major things, like knock retardation and the like, the best would be to retune the standard ECU (personally) as it is unrecognisable to the cops, unlike any aftermarket ECU

Quad throttles will be noted as a modification and there for deemed not allowed, but would be awsome to have, maybe just an extrude honed and port matched inlet with an 80mm T/B would be the go, plus it'll be alot cheaper, if you are going NA power maybe bigger cams might be woth using, if you plan on the rest of the mods, there's an NA SR20DE in a datto 1200 ute in japan that i know of running 302deg cams, making 220hp, 280 with NOS, runs 12.01sec 400m

What comp ratio are you planning on going with? minimum of 12.5:1 i'd say, autech S15 came with 11.7:1 standard, as long as good fuel is always used

The turbo injectors are good for 200kw's so i dont think you will be maximising them any time soon with NA power, and will suffice, no need to go bigger unless you have to, and they'll be the easiest to tune and have the best spray pattern

A good mod to consider also will be a higher final drive ratio and the 6 speed S15 box to have better ratios for acceleration, whilst sacrifising top speed

i need more power, preferably yesterday

hey thanks drift im takin all this into account iv just gotta save up some more money... im getting a performance garage to build it for me... but ill def look into the things youve mentioned
