Turbo

[RunninJDM]

Im new to the integra game, i have a 1991 integra with a B18A1 and pr4-2 head. s1- tranny.
I want to boost it and make around 270-300hp. The guy i bought it from told me it wasnt bored over or anything, but thats the same guy that told me it was vTec... I know ill need a rebuild kit (opinions welcomed for everything, that's kind of what im looking for)
As for the turbo im looking for low end torque so a smaller turbo, If you reccomend another turbo option let me know.(IM LOOKING FOR A KIT)
Pistons/rods( Im thinking lower compression)
Head studs
Valves/springs??
Possibly boring.. cylinder sleeves?
I wasn't going to mess with the cams, but possibly mid power. Like stage 2 or something

For the fuel system im stuck, im thinking 500-700cc injectors. But i have something called Programed Fuel Injection, Will that get in the way of my tuning or anything?

As for the actual mapping and ecu stuff, i was just going to take it to a local dyno and let them figure that out.

If im missing anything or any suggestions please let me know. Also if you want to reccomend me to a site that will be helpful.
Thanks -Keith

LOOKS JUST LIKE THAT

For that power goal I would raise te compression to 10:1. It gives you more low end power and less turbo lag.

Do a lot of research!

Alright thank you, do you sugest boring it out?

If you want a big bore you will have to get the block sleeved, but there's nothing wrong with boring it a little to get fresh metal, that's what I did (to 81.5mm)

It sounds like you need to do a lot more research...You have a b18a1 and you might have a vtec also? do you mean a vtec head or a vtec sticker?

First thing is first. We have a Forced Induction section, this belongs there. Don't bother re-creating a thread, a MOD will probably end up moving this there.

Secondly, we also have a STICKY in the Forced Induction section with FAQ's.

Your car is no different then every other Integra out there, no worries about the "programmed fuel injection." Everybody has it. Assuming the previous owners haven't rebuilt the motor, it isn't over-bored. Typically you want to avoid boring a motor if possible- the more it is bored, the thinner the cylinder walls become. You should only do it if needed, or if you plan to sleeve it and want to bump up the compression.

Before you say you want a small turbo and a bunch of low-end power- think about this. Is this your daily driver? Do you REALLY want to be spooling your turbo from every stop light? Staying out of boost and keep fuel mileage up should be on your mind once in awhile too. Think about the goals of the car in the end.

If you're looking for a kit- look into Turbonetics. If I recall they sell kits for these cars. I could be wrong though, if not I would piece together the turbo setup.

We can't really tell you what pistons exactly to get without knowing your goals, but if it's simply that you want more low end with the turbo I would go 9.5:1 compression. 10:1 is going to take a competent tuner and I don't recommended it when you're still learning as you are. For 300whp your head can stay completely stock. The only upgrade I recommended there is ARP head studs.

As for the fuel setup you should upgrade your in-tank pump to a Walbro 255lph. This requires you to remove the fuel tank and pull the unit out. The fuel injectors should coincide with the power goal:

440cc/min: 300-325whp
550cc/min:350-375whp

As for the tuning- let the tuning shop handle it. You should just have them do the first run on the motor after it is installed, I wouldn't even run it without it being on the dyno ready to tune.

Wow, thank you. I really appreciate all the information also thanks for recommending the CORRECT section thius post should be in.
