Okay so I'm conjuring up images in my head of what can work for a nice 400 whp setup. This will be on Cali 91 octane and I will want to reach this power level on a load bearing dyno (Mustang or Dyno Dynamics). All I know is that the turbo of choice will be a GT35. I'm not new to turbo's but I'm very new to Honda's.

B16 or B18 (C1 or C5)?

To start off I don't have the car or engine. Looking to sell my current car (turbo AWD variety) and want something way more low key but still fun to build.

The budget...well let's just say I want this to be an ongoing progressive project for about a year or so.

So whatcha think?

Are you going to sleeve it or anything? Pistons rods? 400hp is very capable on either motor, especially with that type of turbo, just depending on what you're going to do to the motor and tune. Some people like the B18 over the B16 due to having more TQ with the B18, B16's are known to have low TQ.

the b18 would be the better choice. especially as it looks like you are going to be shooting yourself in the foot by getting a turbo way to big for your goals. the larger displacement will help reduced the completely unnecessary lag from the still oversized turbo.

I'm more than likely doing a similar build, I'm shooting for 400-450 HP in my CRX but I already have a B18C block that I'll be building up most likely, I think I'll bore it so it's a 2.0. Mike@synapse what turbo do you recommend for putting that kind of power down? I was looking at the GT-K line from Turbonetics even though they're expensive.

NOTE: I edited my first post because I should have pointed out that this will be on pump gas (91 octane).

Yeah I'm looking into all that stuff...I know that the bottom end will have to be built. But, how much of a torque difference is there?

Also from what I gather the B16 and B18C5 have the same head? Or does the B18C1 also share the same head? This was the only reason I was also considering B16.

How about turbo lag between both? Is it a big enough difference to put into consideration?

Do you think the GT35 will be too big? I was looking at GT3076 also but I figured I would go with a turbo that I felt may not have to be pushed as hard to reach my desired power levels.

Oh and thanks for not telling me to "SEARCH N00B!".

There are plenty of turbos from the Ball-bearing and journal bearing series of Garrett, as well as some Borg-Warner units as well. I'd look to find out the manifold you plan to use, since you have an EF/CRX, I quite sure room is an issue. You can also looked to the silver surfer, which was originally designed for thee EF/CRX 400+ hp crowd.

gt35r is to big for that power and gt30 is alright, but to be honest the best bang for your money is a 57 or 60 trim turbos. hell my homeboy ran high 10 with a 60-1 on a stock bore gsr running 110 octane.

hbyrd8701

forgot to mentioned it was at 22psi of boost and the funny thing is that the motor never been to the dyno, tune or anything of that. just street tune.

Well I picked a GT35 on the idea that I wouldn't have to push so many PSI through the turbo to reach desired power level. I don't really want to push a turbo to its limit. Also I am never going to use anything higher than 91 octane (providing I don't move somewhere that sells 93 octane). Will any of those turbo's be able to flow enough to make 400 whp on a load bearing dyno on 91 octane?

Also thanks for the reply!

well go with the gt30 cause another friend of my had the 35r on his fully built sr20 240, had for 8 month, wasn't really happy cause of the lag then sold it. also that car that ran high 10 also had a 62-1, I think it almost the 35r, was lagggggggggge has hell at 13psi. I rode in it twice and it took forrrrrrrrever to do anything.

I'll look into GT30's then. Though it's tough for me to gauge setups on these forums because people like to be extra vague like not listing what gas, psi, and dyno's they use

hbyrd8701

yea....just watching out for yall. I fill that the gt35r is really good for bigger liter like h22, k24, 4g63 and ect ect ect.

Good point. With a GT30 will I run into wheelspin bad issues? The scheme I had planned in my head was that with GT35 I wouldn't have to worry about it as much due to lag...but if the lag between the two is close maybe I'll just go with GT3076 or something. Whatcha think?

hbyrd8701

depends on the motor and tranny setup. the gt30 is not as of a lag than the 35r but there are other option, that is your plan or goal.
