Help please 98 integra project

[sumdumfuk]

Hello, I am a newbie out here so please be patient. My son has a 1998 Integra that he would like to start building a bit. It has a standard B18 non V-Tec engine. He has decided that one of rhe first things he want to do is change the stock intake manifold, throttle body, fuel rail and injectors. He purchased a Skunk2 CARBEO-D-537-2
racing manifold, a 75 MM throttle body, rail and heres where the problem and assisatnce is needed. The injectors he purchased he got off eBay from a seller which are from a Mitsubishi Eclipse #MDH275 which are supposedly 275 cc injectors. The problem I am having is the injector is physically larger diameter at the base then the stock injector thus it won't fit into the manifold o ring. Can anyone tell me, will this combo work? Are these injectors right for this vehicle. The guy who sold me these things claims he puts these in these cars all the time and he's sure they'll fit. I think he's full of it cause these things are almost 1/4" wider at the base than stock. Can anyone advise PLEASE??? Also, does anyone have any input on the selection of upgrades? If it's determined the injector will work in an Integra, is this a good match for the size of injector, throttle body with the manifold? Any info will be greatly appreciated. Thank you in advance!!!

I'm no pro by any means, but I feel that he could have done some other bolt-on mods that would have been beneficial; not to say your son's upgrades didn't make a difference, I just feel there could have been easier upgrades made without so much hassle, and potentially cost.
Good luck, dude; and welcome to the site. Everyone is pretty honest, no matter what you may think of their personality; which is a benefit, considering you will end-up in the right place at the end of your journey :thumbs up

Hilarious screen-name, btw! :rolf:

I would have gone with your standard bolt-ons but the only way to learn is to dive right in sometimes.

The car wont run correctly with a 75mm throttle body and a after market intake manifold...He needs to either sell the parts, save them or buy internals to complement the other parts he purchased.

1998 Integra help!!!

Can you be more specific with the problems he may face and what are you considering internals? Is that like cams ro pistons etc???

What other bolt on's are you suggesting???

Honesty is great. What other bolt on's are you suggesting!!!

To get good use out of the manifold, throttle body, and injectors. I think they are probably talking about your basic bolt ons like cold air intake header and exhaust and probably some internals like cams, pistons, maybe port and polish.

x2
and then take the money and buy some headers for an LS INTEGRA, short ram intake & exhaust setup for now. no need for injectors yet.
then hit the forum for a while and see what works and what doesnt.....see all the options 1st, then figure what you wanna do.
good luck

The biggest issue your son is going to have is the car not wanting to run properly. The reason being is Integra's run 240cc injectors, putting the bigger injectors in the car is going to make the car run very poorly. He will need some sort of fuel management in order to fix that. The bigger TB and Intake manifold are always a good starter upgrade, Although 75mm is a bit excessive, what brand is it btw? I would agree that a Header (4 cylinder honda's run a header, not header's), an exhaust and cold air intake should be next on the agenda.

Honestly I would stick with the stock injectors until he either gets cams or raises the compression. You could advance the timing on the distributor some to make the car a little more peppy.

Theres always the Vtec head swap option. If you do a quick google search on LS/VTEC conversion you will find thousands of links explaining what you will need and how you do the conversion.

You just purchased the wrong items out of order is really all you did. The typical set up n the easiest without getting to much into the 10 grand price range would be to keep the motor how he has it the stock non vtec and put a turbo kit on it, with the manifold and throttle body he has, even though the throttle body it quite excessive even for high hp... All motor you want a 68mm n turbo u wanna stay around 70mm maybe a 72mm, make sure you port match the Throttle body to the manifold too.

First thing is figure out a plan together, what route is he taking it, all motor and boosting? they have different steps and parts you need to buy first and last. If you are going to be boosting, you dont want to waste your money on a intake and header or even a exhuast cuz its all going to be taken out and not even used when you add a turbo.

If this where me, id do a ls non vtec with a turbo.

I would keep everything stock, save for a good turbo kit that will do like 8 pounds of boost, buy that, add the manifold and throttle body get new injectors to support the hp out put he will be running and call it a day.

He could have around 300whp without really risking breaking stuff inside.

Now option 2 and obviously cost several thousand more, would be to get eagle rods, some 9:0 compression pistons, prolly could even do new valves and springs, have it machined and put together by the machine shop. Now your talking about pushing over 300whp without breaking stuff, id say give or take good for about 350 max? PPl with this set up correct me if im wrong plz.

Now if he doesnt or you dont want boost aka turbo, i would look into a LS/vtec conversion meaning you will need a vtec head (GSR head) and have a machine shop tap the block for a oil line and various other odds and ends as well. If you go this route ppl generally do a all motor application, so i would look into high compression pistions lik some 11:5's, new rods, largers cams, all new valvetrain and so on. As you can tell probly already a all motor application is going to be far more costly and doesnt produce nearly as much power.

I could go on forever so im not going to, if you have any questions about what has been said just ask, but long thread short, save for turbo and build the bottom end up, or just save for turbo and dont run much boost like around 6 or 8 pounds max. Good luck with the build

He should not install that IM and TB unless he plans on getting a turbo. Those parts, especially the TB, are way too large for a B18B with stock cams/pistons, stock compression. The stock B18B TB is 58mm, (a stock B18C1 TB is 60mm, by comparison), a 70+mm TB is only good for a very aggressive (non-streetable) B18B all motor build, or a turbo setup.
The fuel rail is also useless except for turbo'd engine, and only a high boost turbo engine at that which would need large amount of fuel. The stock rail is large enough to supply fuel for a low boosted engine. But many people get them just for the looks, it won't hurt, feel free to install that but it won't accomplish anything towards making additional HP.
I have heard of DSM (Diamond Star Motors, Mitsubishi) injectors working on Integra engines, but I have no experience with them myself, hopefully someone will come in here and help you out on that fitment issue you have. And yes, he will need some form of fuel managment system to retune the a/f ratio if he replaces the injectors, and will need a tuning system regardless for further tuning if he's planning on building the engine internals.

I think he is planning on turboing the Integra down the line, but that won't be for a while due to lack of funds.

Do you have any experience with turboin the Integra and is there an economocal set up. Funds are really tight for him???
