Newbie Looking for Big Help

[VooDoo|io]

i'm kinda a newbie but with big dreams and i whant to do the folowing to a 2003 eclipse gts : to ajust de hks supra bi turbo kit to the eclipse(providing custom manifolds and exhaust pipes) , new JE Pistons engine internals (cramshaft,valves,piston heads...,all the internals) , new racing clutch (kevlar/ceramic) , and a six speed tranny wtich i heard its hard to get (and probebly here i nead all the help i can get) , a lowering spring kit with blistein shocks , a body kit (i saw a really nice one from JSP + a really nice rear wing from JSP too) , wheels of course
(their size depands on the tranny setings) , a direct port nitrous sistem (saw a nice one from NOS) , seats and interior from sparco (wheel,seats...) and i thing this kinda cover it if i left anything behind please let me now.

i'm willing to invest about 15 k$-20k $

all this being said please don't show me the or the and things like this i want to do it and i am determind to do so

Well, forget using the supra TT kit.

Valvesprings, camshafts, pistons, throttle bodies (up to 6 TB valves in a single application), billet titanium connecting rods, vernier cam gears, and port/polish for the cylinder heads can all be had at RPW Piston wise, I would raise the compression to 9:1 or 9.5:1 as the stock 6G72 has a CR of 8.5:1.

They are also working on a single and twin turbo kit with the single kit to put out around 400 whp.

one thing you will need custom made is the intake manifold as no one makes one yet. the exhaust manifold for turbos can be had off a 3000 GT VR-4 or Dodge Stealth RT.

Suspension wise, I would choose JIC Magic FLT-A2's. They are the premier suspension system for our cars. Also, you would need an aftermarket sway bar and rear strut tower bar. All of these can be had at Road///Race Engineering

Transmission wise, get a fidanza flywheel. This is lighter over the stock one and with less rotating mass, the engine revs faster. clutch wise i would have to say either the Centerforce 2500lb or ACT 2600lb clutches.
The racing trannt would have to be custom made, but if anyone could do it, i would say Road///Race Engineering would be up to the task. If you really wanted a race disc, they can get you one.

Direct port nitrous would best be with NX using at a max 75 wet shot until your engine is finished being built, then you could run about a 100 hp wet shot.

Another forced induction option is to get supercharged. Ripp Modifications out of New York currently has a supercharger system that at 11 lbs of boost lays down over 300 whp. With your engine being built the way it could be, you could easily run 15-18 bs of boost, if not up to 20 psi. They also sell race headers which are currently beng used on a race car.

With the RippMods Supercharge Drive System (SDS) at 20 psi, you are looking to have almost 500 whp, with the above engine mods as well. Add the 100 shot of nitrous and aftermarket intake manifold and headers, maybe around 620 whp.

Another thing you forgot is the chassis stiffening kit from D3 Designs . This will increase your chassis stiffness and give you substantially less body roll. With the above suspension mods, you car will handle with the best of them.

One area of concern would be the stock driveshafts. They will not be able to handle the excess power. New ones would have to be fabricated. RRE might be able to do this or you may have to get them custom made.

Body kit wise, I would choose the Bomex Kit. It is by far the most aggressive, newest, and best looking bodyit on the market for the 3G right now.

10x a lot man you gave me a lot of work (told you i'm kinda newbie)
so one question for now becouse like a newbie NOS is the first thing i looked into why not direct port?
and of course in large terms (estimating the custom parts too) whould i feet in the barge (15k-20k) with the bi turbo kit (from what i understood it geeves you more boost in low rpm)

10x a lot man your the only one in the spirit of this forum cuz nobody else would point me in any direction

10x a lot

forgot something what is the difrence betwean whp an hp i mean 1 hp = x whp

[johnnyBgood]

Do go with direct port. i did not say not to. Merely run no more than a 75 shot wet (meaning fuel added to the nitrous, makes it safer to use) on stock internals and up to 100 after building the engine.

With the twin turbo kit (not bi-turbo), boost will still have lag. There is nothing you can do about that, turbo wise. But you can program the nitrous at activate until boost is achieved.

and i do not understand this statement: whould i feet in the barge

I dunno what you are asking

[VooDoo|io]

sorry about that statement i mean if i could fit in the 15k-20k sum of money that i'm aiming for,and sorry for the bi turbo thing i saw something like and confuzed the terms sorry again

[VooDoo|io]

by the way why is evrebody saing that the new eclipse in worse then the old models and engine tuning i cann't understand why an inline 2.4 is better then a 3.0 v6 ,it's harder to tune a v6 or what?

[johnnyBgood]

The V6 has less cylinder volumetrics than the I4. The V6 has .5L compared to the I4 which has .6L.

The V6 is a much harder platform to work due to the small engine bay. The V6 is shoehorned in there and gives someone not alot to work with.

However the 4G64 does have lots of room to work with, plus it has interchangeable parts with the almighty 4G63 such as valve springs and....TURBO MANIFOLDS. Also the 4G63 DOHC head will bolt up to the 4G64.

All versions of the 4G63 turbo manifold bolts up to the 4G64. However, the 2G eclipse manifold sits the turbo to the left side of the block (looking at the engine from the front of the car), while the EVO manifold sits the turbo to the right.

Using a 2G eclipse manifold, any turbo bigger than a 16G will require the removal of AC due to the size and placement of the turbo, while using the EVO manifold requires the movement of 2 coolant line. I don't know about you, but i would rather move the coolant lines around the turbo intake than lose my AC.

Also the 4G64 takes to boost very well. Running 12 psi with a properly made system can net between 280 and 300 whp on a stock engine.

Install some forged pistons, connecting rods, valve springs, sleeve the block, port/polish the head and you can run upwards towards 20 psi. There is a company in Texas that has boosted a 4G64 upto 35 psi which let them dyno in the 650 whp range with NO nitrous.

Another factor is weight. The base 3G eclipse (RS) with a manual tranny weighs in at a hair over 2900 lbs. The 3G GT weighs in at over 3400.

Basically, the 4G64 is easier to work on than the 6G72.

[johnnyBgood]

Oh and the difference in HP and WHP. Many auto manufacturers make cars and rate the power at the flywheel or crank. This is HP rating. However this is not accurate to the power you put to the ground. For example, Mitsu says my car has 154 HP. At the dyno, I found out that the car had 103 whp. About a 32% drivetrain loss, which is the auto tranny usually sucks. The manual tranny dyno'ed at 117 whp.

With some mods, my last dyno was 114 whp and 136 lb-ft of torque.

10x a lot for the info but it's to technical for me and i don't know all the english terms for some engine parts so please give some links or thing or something where i can do my studying for engine and i would like some good studying so i can really understand an engine

10x a lot for the info again and for takeing the time to tutore me

lk 10x a lot i'll be reasearching now

by the way are you US and in so from what state/city
(ofcourse if you what to shere that info)

[VooDoo|io]

by the way i see here (on a forum) talking about the 4G64 and it's refering on beaing mounted on a 96'-99' spider eclipse and on a 7g galant so do these cars shere the same engine with the 03' eclipse or i'm just plaine stupid (if i'm stupid please tel me the engine code of that damn V6)

[VooDoo|io]

and another qestion what engine whould you concider best to tune (i mean ricer ones) a 3G63 or a 2JZ63A (the supra if i didn't get it rong) or any other (for a friend of mine who is interesting in changing his engine on a car you've never heard of so there's no point in telling the name)

[VooDoo|io]

and yet another question : is there a soft prog that can help me build my car installing and unistalling parts to see the advantages and disadvantages of some parts i don't mean with a full part data base but at least where you can put the atributes of the parts and tell you what it's going to do to the performance of the engine?

[johnnyBgood]

Ok. The 4G64 is the engine code for the 97-99 2nd Generation Eclipse spyder, 2000-2004 3rd Gen Eclipse RS/GS models, and 99+ galant.

The engine code for the V6 is 6G72, which is also used in the 3000GT (GTO).

I would consider the 2JZ the best to tune because i have never heard of the 3G63. Unless you meant 4G63, in which case i would go with the 2JZ. The stock bottom end is virtually indestructible with several Supra's running 900-1000 whp on the stock bottom end.

For the program you are talking about, I do not think there is, at least in America. Check out the New Eclipse board. There is alot of info on that site as to what works and what does not, as well as good vendors.

If you do have a question about the performance of a product, your best bet is to call the manufacturer and talk to them about the product in question. I know from personal experience that RippMods owner will talk your ear off about it.

Curious as to the name of the car with the 2JZ63A engine. I searched for it on Yahoo and came up blank.
