My ecu has functiion for launch rev limmiter, Mini spool can be great for drag racing, but how will it behave on the track? Yes it stil has leave springs, fitted with slapper bars, no pannard rod, traction not to bad, but road holding leaves much for the imagination. Have you had any sucsess in...

Hi there, what do you mean by 2 step? I have heard of the term, but do not really know what it is, can you please explain. I have a computerized system that can give me a stage for every gear, and can come in progressively with rpm. I`m planning to build a 3link or 4link with pannard rod. what...

Jip with some calculations experiance tuning and boost control i recon it will be possibale, bus space is also a major concern, fitting the 1u will be a mission in itself. And in our well develloped 3rd world country, there is onley one drag meeting a month, at best, and big events is about 6...

Sounds stupid I know. I was trying to point out is that for example its no use in putting on a super fowing pro stock part if the other parts in the system cant flow nearley the same amount. Everything has to compliment eachother, every day of the week.

In my case the nos is planned just for a extra power boost for drags, but yes, nos is more for the weekend racer than everyday street power. Turbo power will be to much for my application, wont get the power down for the circuit. And it will be a good thing to get rid of some bottom end power...

Hi all Rod - I were thinking of the box that comes with the 7m turbo motor, don`t know if the box from the NA 7m is going to take it. the body is light though. What do recomend? Stevechumo- if it can take 300kw + supercharged safley, the same power...

I was onley trying to piont out the relationship between rod thicness and strength is strange.

Makes sence, Your motor is onley as good as the next restriction. And the heads and intake does not look very free flowing. I think the std cams also doesn`t allow large amounts of air to flow through improved manifolds. To me 20hp is a worth wile gain. On my Bmw i changed the whole exhaust...

Hi Sheepers. I hope you make a sucess of your exhaust project. The std design is very restrictive, and i think opening it up can yeild good gains. Going the tri y route should give impressive midrange, and for street use its the best in my opinion. keep me updated. Jaco

Hey justen. Yes i would be quite a challange, but i believe it`s possible. Its the road less travelld, not a lot of info avalible on NA setups on 1uz. If you look at it this way, the std motor makes +- 190kw, with proper setup i think it would take 100kw nitrous safely. Something like a 8...

Thax for your input. I know the pistons in`t that strong, simular to the series1 4age. freind of mine broke his pistons in sthe same way that those in the link that Chicken wing sent. I agree forced induction needs presice tuning (a fine art) About the rods getting thinner, toyota did the same...

Hi Plman. Thanx for the pics. This just goes to show that the 1uz heads responds very well to porting. 112Hp per liter souds very optimistic on factory cams, is this in normal aspirated form? must be forced induction.

hi Hrforever. Very good i think. I have made 2 adaptors, one for a w58 and one for a landcruiser, in very much the same way. and they both work well. they are going around for a year now and no problems. I think you would need about 20000Hp give or take, to flex an adaptor that thick.

Hi Speedrunner. Your flow comparason is very interesting. Ive read somware that n good port job on the 1uz heads hield a 19% increace in flow. wich in theory can bring the flow up to 143cfm. which is still bad. My question is how does it compare to a sb ford v8? say the 302w? Have you done flow...

Hi to All. I`d like to know who has build a normal aspirated 1uz. Any mods form air induction to a full build, with power ratings. I cant seem to find much info on NA 1uz motors, yet i believe they have lots of potential. As far as my reasearch goes so far, the ristrictions is the restrictive...

I can`t help but wonder why do you want to change the rods? I think the std rod with arp bolts can take most of what we can give it. Mabe if you are planning 2bar boost or 8500+ rpm. Has anyone broken a std rod? Is it a weak point in the motor? Ive boosted 4age motors 2.4bar at 8500rpm with...

Hi All. Well i like forced induction, it makes heaps of power and is sometimes even cheeper then NA. But i love NA, i belief its an art, and it sounds so good. I am also a big fan of Nitrous Oxide, it gives great bag for the buck, and if it is switched off you motor is stil standard. My...

South Africa. Nice wether all year round. not to hot not to cold.

Hallo. Sounds to me like the signal for that injecters is short to earth. Or the signal was short to positive, wich could have damaged the drywers in the ecu. Take the signal of the injecters and meassure for earth, if there is, then plug out the ecu and check again. If there is still earth then...
