Hello - im looking to take my stock 2k lude and give it some more power. h22a vtec is 200 hp stock right, so thats about 170 at the wheels? oh, i forgot to mention its a SH 5 speed. Anyways, i was told that w proper fuel managerment and 93+ octane, i could run 10-12 PSI on STOCK INTERNALS. im not quite sure if that is true and the last thing i wanna do is blow up this motor. its only got 35k miles on it. is it possible to hit 300 Wheel HP safely? Can i hit 300 WHP on a N\A motor if i add vafc, header, intake, exaust, pullys, timing belt, ect. Id appreciate anyones expert advice as to where to go from where i am now. Thanks

 

no you can only run about 5-8 psi boost on stock internals to be safe. 35k is a god number to start running boost. vafc will help tuning, but not enough. you will not hit 300 hp on bolt ons (header, intake, exhaust, etc). i work at SRTmotorsports and there is no way that you will hit 300 hp expert advice. boost is the best was to go but if you don't have money to keep up the turbo, it gets expensive to run boost. if it is all done right. you shoudl be fine, but for tuning hondadat is most likely your best bet for tuning. i run h23vtec runnign 18psi boost, with only vafc i want hondadat but cash is limited. any questions feel free to ask.

 

hey - i appreciate the quick responce! i jsut posted maybe 10 min ago, went to go walk my dog and make some coffie and by the time i was back , i had a reply . So if i got a good turbo kit (drag, fmax, greddy) w\ a good intercooler set up, keep it at 8 psi - do you think i run the risk of blowing the motor? Ive seen a few good turbo systems coem w\ a FMU and larger injectors (440c i think was on a fmax kit - tho i can easily be wrong im new to alot of this stuff) - anyways, w\ turbo, exaust, pullys, intake, and the vafc chip to lower my vtec (i was thinkign 3500-4000rpm) is that safe? please bear in mind that this project will span over the course ofa year, and hel things go wrong, so lets say year and a half - but im totally dedicated to it, and id love to pick your brian about this
thanks

Edit : is hondadat the same as the hondata chip? Im kind of lost as to how that system works as well. I buy the chip and take it to a motorsports shop or dealer and they basically use it to reprogram my cars computer?

 

Hello Lude2kFx

I personal don't have a turbo on my prelude but I will try and help you out. If you look at the Greddy website it offers the turbo kit for the 97-99 prelude. My understanding it that the ECU is different from 99 to the 2000-2001 models. But that doesn't mean you still can't use the turbo kit. You will have to get an engine management system to take the place of the blue box. Hondata is one option and AEM EMS is another option. Here is the website to hondatat.

Do some research on there website and also use the search function on this message board to help you out with some of the most common problem that come up with a boosted lude.

Here is a thread that will help you get started and by all means if your question have not been answered created a new thread and ask an intelligent question. There are many people here that can help you build your prelude.
Just one more thing, I all most forgot to tell you. Your ATTS doesn't like high HP Applications.

what kind of hp would this produce, and to the wheels?

 

hey, i have the turbonetics turbo kit and it claims to give 275hp to a vtec lude like yours with i think 8-9 psi, not certain on all details

i have a prelude se, but i have not dynoed yet

Real nice lude .

 

do your self a favor and do a search for ATTS. it will possibly change your mind about boosting when you realize you cant change the ECU and therefor wont be able to safetly run boost. unless of course you want to waste the ATTS unit and defeat the purpose of the Type SH.

Screw the ATTS, boost the lude!!!!!!!!

 

yea get boosted, just make sure you use the stock honda oil filter. i had a bad experience with the K&N oil filter just 48 hours ago

 

Could someone explain what ATTS is ... sorry new to ludes...

 

what kind of "bad experience" with K&N?

 

Ideal, are you talking about my lude or a lude putting 7-9psi boosted? well i have seen several low boosted ludes that just don't have the money for internals and good tuning. and they only run about 250 at most whp, w/ about 210 wtq. i run 11psi all day and put down just under 300whp if i can find my dyno cahrts i will post them. when i tune the boost up i can hit 325-330 whp i believe, nota true daily driver right now though, more of a weekend worrior with alot of use, on the weeknights.

You can hit 300whp but you'll need to do one hell of a lot of modification inside and out and your car will be worth less than the engine itself. So all in all NO you can't.

My friend, who posts under Firedrake, has a VTEC Prelude under 9psi stock bottom end. This is his sig:

Firedrake:
1996 Honda Prelude VTEC @ 11 psi
Dyno: 311 SAE whp untuned @ 9 psi
1/4: 12.71 @ 115.8, 5600ft elevation, 1.96 60ft

He can afford to run 9-11PSI on a stock bottom end, so when it blows he'll have a beater to fall back on. Then he'll have to take the thing apart and he has all the time in the world to build the block. Do you have another form of transportation?

Also about your ATTS, it'll have some issues past about 280whp. I bought a P5P block w/ internals that I had to make a intermediate shaft bracket to replace the ATTS unit that it came with (I have a 4th gen 5 speed VTEC). So if you want to get rid of the ATTS then I can fab you a bracket like mine. But you'll need a different tranny becaust the ATTS tranny has different output shafts than the rest of the Preludes. But if you go big turbo then you'll need some sort of traction control, like a quaife LSD. All in all it'll be expensive to turbo your SH. Hope this helps. Good luck.
