I have a basic engine 16 valve no vtec, I'm looking for a little direction...I'm wanting to go with a the boost to come on at a fairly low rpm becuase this car will be designed for serciut track not drag racing...not sure if I should go with the gsr motor or build on what I have, if anyone has tackled this please give your imput, it would be mostly appreciated

The GSR motor is definitely a better option, building on a platform that already has severe limitations isn't practical.

okay thank you...thats deffinatly a helpfull start to things

so you thinking more on higher compression engine with a lower boost?

 
Rep Power: 0

A GSR motor would be way better than what you have now. You don't need a higher compression. You might want to just get some better pistons, rods, valves, and springs. You can get a big turbo these days with little lag time if you buy a quality one. Spend your time on the suspension. That is where you will make your money and a serciut track.

Yeah I'm planning on throwing low compression pistons in the engine...not sure weather i'll put the money into port and pollish, becuase you can basically get more cooling with a better intercooler. Vavle springs wouldn't have been something i was thinking about doing, but that makes sence. I want my power to start on the low end, i do want it to continue into higher rpm, which makes me want to adventually want to have compounding twin turbos...the whole idea with putting all this into a sedan, is i don't want ppl to see the defete coming.

For suspension, I am looking for rear disk brake setup from a 97 si, and after that i'm going to be looking at dealing with the suspension, not too sure which way i'm going with that, but thats what I'm trying to do now...becuase this project is just starting...all I have so far is just some Eibach sportline lowering coils, and a rear sway bar

?
this is just old school, but if you lower the compression, you will have less torque in the lower range?
for better power in low range, you need a turbo that will work at lower ranges (less lag, as stated above), but it will limit the upper range.

If you want power than starts in the low end and continues through the entire power band then get a supercharger and build off that, if your not happy with the top end power you could add a turbo.

Or if you really want to spend a lot of money and time tunning use both.

Supercharger ftw. Twin charge it if you wanna go big.

i'm not planning on dumping too much coin into this, but it going to be a fun car when i'm done...at this time, a supercharger system with a turbo is far too much money for me to spend. What I'm planning on doing, is building this car so that on the weekend I plan to go race, on monday, it goes to work with no hang ups, but I want to have a fair amount of power, which is why I wanted to install compounding twin turbo's adventually, lots of power in top and bottom end, vary little boost leg.

For now, I'm searching for a good price on a GSR motor, and I'll start making the engine ready for the turbo so when I do slap it all this together, I will be spending time at the track testing and adjusting, not back in the shop fixing week points that I cheeped out on when building the engine.

I'm not sure what size turbo to go with at this point, I would like to start off with a single turbo, possibly ripping it off of a production vehicle thats already smashed up sitting in the junk yard. I'm fairly limited on funds, but I'm still planning on building this car right, even if it takes me a little longer then I really want

Your severely underestimating the cost and difficulty of designing a compound twin turbo system to run off a 4 cylinder motor, you should do more research and re-evaluate because if your looking to do a budget build there are many much more practical and affordable options.

okay, like?

Taking your time and doing it right is the way to go. It took me years to do my SRT-4 the right way. In order to do it right you going to have to spend money though. Good parts cost more money than shitty parts. I'm still new to Hondas, but so far they seem to better than what I thought they would be.

Mini Bomber, what more affordable opions did you mean...like i said I'm just starting out on looking for ideas on my project to move ahead and build something reliable, practical, and fast

was wondering if this kit would be any good to start with?

unh...
no cheap shortcuts...
you need to spend for power and reliable...
Lower range torque requires or volumetric capacity (engine size), or higher compression (which automatically throws you on a lower turbo boost).
So a bigger motor is warranted, and lower boost with a smaller turbo for lower lag (unless the statement above that newer turbos shows smaller lag is true, to which i am not completely sure).

 
Rep Power: 0

Big turbos with tons of lag time is a thing of the past. Some big turbos DO HAVE lots of lag time, but not all. You can go big with a good turbo set up if you do it right and not notice any lag time. There is no point in doing that if your not wanting to spend the money. Buying off of ebay is big chance you take in things not working out. Yes it seems like a good deal, but do ever see a nice clean, fast car rolling around on ebay crap? When you do see one it wont be rolling around for long.

lol good point...I apreciate the imput so far, its great...I'm looking for my new engine right now, I'm wanting a good amount of power, and I don't want issue's so I'll for sure stay away from the ebay crap, thanks for the help thus far...next step is building the gsr engine to handle the boost...which is were I should be shortly enough...that is when I pick up the motor of course other thing, sticking with the 5 speed, not upgrading to a 6 speed, this was what i was thinking, turbo is there for a reason, more rpms the better, 6 speed would possibly limit that possibility....and imput on that would be great, thanks

Do some research on turbo set-ups to decide what your power goals and budget are..

You could easily spend $6k for a minor motor build and turbo, but if you have the self control and will keep the boost around 5-15psi you could do a much more cost effective build with just cams, pistons and turbo. The most important advice I would give to anyone going turbo is to spend on a quality EMS if you don't want to blow your motor and don't forget that your car needs to be able to the handle the power your planning on putting down. If you go turbo also budget for quality tires, brakes and suspension.

You rarely/never see staged turbos on 4 cylinder cars, because it would be a nightmare to design the system and likely be completely custom. A quality ball bearing turbo spools so fast anyway the classic issues of massive turbo lag is a thing of the past. It would actually be less expensive and probably ever more cool to have a turbo-supercharged motor, but even that would cost five figures.

I appreciate the advice...for now, I think I'll stick to the turbo setup and try that first, if I want more, then I will upgrade to adding the supercharger. Now that I have a better idea of which direction I would like to go, I have to start searching for my motor and what suspession I should go with....thanks for the advice.

if you want quick spool at low rpms and no lag but the benefit of turbo get a centrifugal supercharger, you can still intercool it and make big power, oe more expensive variable geometry turbos will do the same thing as a 2 stage setup with 1 turbo.
