7mgte H/P additions ..

[slacker]

I want to see about 400HP @the flywheel ....

7Mgte ... what would be your suggestions ?

[bgrieger]

400 flywheel...upgraded factory turbo, exhaust, intake, boost controller, 550cc injectors, fuel pump, fuel pressure regulator, lexus AFM, alphabet soup fuel computer. Should net around the 400 flywheel mark, give or take.

bgrieger, What is a alphabet soup fuel computer have never feard of it before.

[bgrieger]

HKS has for fuel control: VPC - FCON - GCC - SAFR
Apexi has: SAFC

etc...
Then there's the boost controllers...

see why I refer to them in general like that?

[Jeeves]

w/The VPC he wouldn't need the Lexus AFM :-D.

[bgrieger]

very true...One or the other. I just started spitting out all the random 3 and 4 digit letter combinations I could think of in 10 seconds or less....I think we might spend too much time on the cars though. I can remember a slew of little letter combinations but have trouble remembering people's birthdays...

[Tofuball]

Well, yeh, thats cuz people's brithdays dont STAND for anything

S-AFC = Super Air Fuel Controller

December 8th, 1981, doesnt exactly lend itself to memory :p

Keep on wrenchin . . .

thats awesome ... thank you . cant wait to get going on this puppy .

I spoke with a guy i know that works at toyota, he told me to do the following:
NA cams, lexus afm, 550cc injectors, and i'd b running 380 easily...if this is tru or not i hav no clu...but i would assume with the propper tuning it shouldn't b 2 far...on other forums, i've read that tha NA cams add 30 horse 2 tha turbo motor...but don't quote me on all this cus this isn't my talk, its all stuff i've read around
hope that does sumthing
peace

The NA cams are worth a bit. The bit depends on the power the engine generates before doing it. IMO, if you have them available, go for it, but don't spend any real money on them. There has been a positive dyno run or 2 proving the NA cams work (actually, only one does anything...the other is the same as we run...can't remember which it is now). If you don't have them, or you have to purchase them from another owner, look into webcam regrinds. Much more aggressive than the NA ones still.

My list above pretty much covers all the parts required to build it from scratch. I take it your mechanic friend only gave you a shortlist assuming you had the basics covered already. If you want to trust a 15 year old fuel pump to keep up, or try it on a stock exhaust, go for it. You won't make that power level for long, but I believe everyone should try something crazy once.

Those dyno runs are much disputed bgrieger. Mainly because one was run while cold, and the other run while hot.

[bgrieger]

True, but both did demonstrate they did at least a little. Like I said, if he has em laying around, sure, install away, but if he has to spend, buy something better.

[repinS]

Hmm, how were the hp/torque *curve* gains for the NA cams? You might've gained an itty bitty in terms of peak, but what about everywhere else?

[bgrieger]

I only remember the debates off hand, though as I recall, the car loses a hair at the bottom from overlap, picks it up through the mid range and gains a little on the top. All in all, were talking perhaps 3-5% more real world peak power.

[Jeeves]

That's about all it netted. One guy claimed a 25whp increase but I never saw proof of that. Really, I think it's more of a seat of the pants and "Oh, I feel it doing something different" placebo type effect. The rule of thumb I'd always heard regarding 7M cams was that you can't really make more power, you just end up moving the powerband around. With anything near a stock vehicle this logic seems to have held true.
