Hi

I have been lurking as a non member over the past months looking for information about different turbo setups and sc setups. I think I have a fair understanding of the most common kits out there, and how much they would cost approx. (Not counting possible problems)

In any case, FI the Honda seem to be 5k$+ for the sneek solutions and 7-8k for a decent inlinepro turbo setup. Correct me if I am wrong. Then drivetrain costs add to that if the power exceeds ~300rwhp?

What I am thinking is that this spring I will turbo or SC my Honda 2 litre ym2005 european version. Will it be better to put some effort into the whole thing and build a own turbo setup from parts recommended by experienced turbo users or is it just better to get a kit? I do have knowledge in welding and i have a friend willing to help that did some custom homemade turbo setups. For example on the Porsche 928.

I would like 300-350rwhp. Also aiming for an efficient setup. Not too big injectors. Stock would ofcourse be lovely, but I guess it is in the grayzone.
Is the DIY route worth it? or should I just get some kit like kraftwerks when it comes out or maybe some secondhand inlinepro parts or maybe a vortech? Greddy maybe is an option too?

Looking for opinions from s2000 modders/drivers that actually DID the diy route.
Others advice are welcome too ofcourse.

If you can make a custom kit I'd go that route. 300-350hp will be VERY easy with a turbo - you can make 350 on only 7 psi! Keep your stock compression, go with a short top mount tubular for power and ease, 3"dp, 2.5" charge pipes, wide intercooler core (mine is 4"), and a GT30 series turbo with .62ar hotside and 3" outlet. Your spool up will be insane, and you'll make great power. You will probably hit nearly 400 on 9-10 psi and stock compression.

This is the setup that I have - and I'm making 400 on 11psi WITH lowered 9:1 compression. Don't worry about drivetrain stuff with only this much power. Stay away from launches on soft tires and you'll have a nice working driveline for years to come

Oh, definitely think about getting wider rear tires. 265/275 is the optimal width you'd want to go for IMO.

Intresting, so you say that 300-350 rwhp is reliable on a stock compression. I don't wanna kill my car and would like more opinions on this one. Have seen 7psi is "safe" in other threads tho.

Also I am not that familiar with the terms you use for describing your ideas on setup.
Would be glad if you could comment!

short top mount tubular for power and ease
What is a tubular?

.62ar
Guess it is the volume/size of the exhaust side of the turbo?

wide intercooler core
What exactly is wide? The coolingpart of the intercooler? If yours is 4 inch, doesn't that mean the thickness in the cars drive direction?

Any thoughts on the injectors?
Any advice or guidelines for the exhaust manifold?
