i have a a type r swap in my 94 civic coupe. its to damn slow so i bought a crx and its going in a couple weeks. i am going to turbo it and want to make 300 whp. right now i feel alot of top end power and very little in the low rpm range, I suspect itl be even worse with turbo lag.

I think a setup with a smaller turbo will solve this since its spools up faster so ill have boost earlier on.

What kind of setup would u guys recommend for this, its a jdm spec itr stock internals. 11.1 cr. And how much psi of boost do u guys this is nessary to run to get 300 whp.

Not sure if you know this, but thats pretty much all hondas are. Hondas dont have much torque and pretty much no low end. All the power is made up top. On the other hand a type r motor can make 300whp usually on 5-6psi of boost. A simple t3/t4 turbo along with some ems and fuel upgrades and you'll be set.

Read the FAQ for starters. You dont base any of your goals in terms of PSI, especially without knowing the turbo. The static compression ratio isn't a huge issue, but your turbo choice and power output will depend on your IAT's and fuel grade. What grade fuel do you plan to run on this build??

Another thing...a 94 coupe with a turbo ITR engine would be a better bet than a CRX IMO. The CRX platform doesn't offer a lot of space for turbo parts...especially with a swap

Thats going to be an oversized, laggy turbo to make that kind of power at such low boost....again, dont use boost pressure as a factor here

i have a a type r swap in my 94 civic coupe. its to damn slow


its too slow....ha i loved my itr swaped hatch it ran low 12's with just bolt-ons...and lasted 100k+ US miles till i sold it

You think a t3/t4b with a stage 3 wheel and a .48 or .63 ar would be laggy? I dont. I just said t3/t4 as a general sized turbo, and I said 5-6 psi b/c based on quite a few dyno charts i've seen of itr motors... thats for the most part all it takes to make the 300whp like he is looking for.

OP check out the GT28 series turbo's- dual ball bearing instant boost!

drop me a line at jtoedtm@clemson.edu i have a setup for sale---

I'd love to see someone take something like a 57 trim in a B housing and make 300whp on 5-6psi. Wait...i think i did that. I have a GT3255b (efficient 57 trim in a B housing) and it took almost 10 psi to break 300whp...the ONLY way that you'll get 300whp is by using an oversized turbo OR running on a Magic Dyno

SpoolnG2

However, you werent running 11:1 compression. You said almost 10psi which means you were probably at about 9. So i'm guessing with the compression difference and a couple less pounds of boost that he should be right around the 300 mark. Maybe not exactly 300 but around the 270-280whp. Close enough in my opinion.

Schister66

I'm at 10.2:1 compression vs 11:1. Its really a neglible amount. It isn't going to account for more than 10whp. Just face it, you're not going to hit 300whp on 5-6psi with a turbo that small.

SpoolnG2

Ok sorry, maybe 7-8. Geez

Coupe93

I have a 93 civic coupe with a ITR swap in it. It worked pretty good N/A...Then I put a turbo setup on it last year....Has a ITS custom turbo and makes 403whp on pump gas.....it has no problem on pulling the weight on the coupe around.

ok im going to be using 94 oct everyday, i want 300 whp everything is stock.

you guys have been a great help. but i still need some more.

if it were to blow what would break the pistons or a rod through the block?

any help is aprricatated a basic setup up of parts i can use would be awsome including brands.

if u guys need any more specifics let me no plz.

Schister66

If you were going to blow it, which shouldn't be a huge concern with 94 octane and a reasonable power goal, you would more than likely crack a ringland and score the cylinder. The majority of engine failures are simple enough where the block can be overbored (if at stock bore) and reused.

As for brands, you can check the Marketplace. There are a lot of good fabrication companies specializing in Hondas and they can hook you up with a good setup. I have personally bought parts from both SPoolin Performance and SLS. My current setup is an all SLS setup and i love it. I would definitely recommend them

your so cool...im only a master tech and your a tool...maybe you cant ger your cars to run as good as mine...let me know if you need me to work on them...my prices are good

ok guys ive decided ill probably go with the gt28r ball bearing turbo. how many lph fuel pump would i need for this turbo and injector sizes etc. any more help will be apreiciated on what sizes of things i need to make this setup work properly together.

get the 255lph HP(high pressure) walbro and some 750cc injectors incase you ever want to upgrade.... and you should be fine

here is mine i went 12.1 @ 116 with a 1.9 sixty

750's are too big for his hp goals,

Maxcapacity

get some rc 550's

Precision 525cc injectors are a better bang for the buck

mine was in a hatch...ran 13.2 with just a filter on the end of the stock plastic intake pipe with the bone stock jdm itr on slicks and with the stock 4-1 header open...ran consistant 12.2-12.4 with jun cams, custom header with open exhaust, bdl throttle body, 310cc injectors and a tune
