Anyone who is sh** hot at physics might know this. IS it possible to calculate bhp from a 0 to 60mph time if you also know vehical weight, ignoring drag etc.?? Im sure it is but hey, its been years since I was at school!

Anyone done some cam swaps with dyno before and afters? What cam profiles are out there in use on NA engines? How much gain in hp? Basicaly is it worth it? I hear good gains can be had by replacing the exhaust cams only. Is this the case?

As per title, I need a set of 7MGE top feed fuel injectors, a standard set will do or may consider an uprated set if there not silly money. Light green 13.8 ohm not yellow 2.7 ohm. Please pm me if you can help. These will be going in the GT4V6 if I can find a set.

Ive been out of the loop for a few weeks as Ive been waiting for parts to arrive and busy with other less important stuff. Id like to say a BIG THANKYOU to David aka Lextreme for sending me ARP bolts and valve stem seals ive needed to crack on with the engine build. Great kit and all perfect...

I realy dont think you should pull the battery terminals off with the motor running. Check your hand book im sure it tells you not to. I cant remmember the specifics as to why not but I know it can fry the reg/rectifier in the alternator.

There seems to be a lot of folks going for ITB's on the 1uz. Has anyone got any dyno plots of before and after fittment with no other changes? The reason I ask is this is complicated and expensive to do, they look the beezneez but how much HP/ torque gains over stock? Or indeed any? 8 throttles...

1 How big are the crank shaft thrust bearings, what loads can they handle? 2 Any of the guys running manual conversions had any problems? How long have this motors been running about. 3 This kinda started niggling at me. In an auto set up does the torque converter ever react against the...

I started rebuilding my cylinder heads today and Ive run into a problem. Looks like my gasket set has got some odd valve stem seals mixed up in it. Question is are the inlet and exhaust valve stem seals the same, im sure they are and my kit is wrong. Looks like I need a new set anyway.

I tried checking the lambda outputs today on the v6 ST185. I thought it maybe a little lean because I modded the AFM. This is maybe goning to be the recipient vehical for the 1uz but 4 wheel drive is sooooo nice!! It makes me want to buy a supra for the 1uz. Anyway the point is its so difficult...

Can anybody recomend a source for headbolts for the 1UZFE. Toyota/Lexus dealer prices for standard throwaway stretch bolts are silly money! ARP dont list a head bolt or stud and dont seem to be in a rush to reply as to if they will be making any. I was kinda considering Ebay item 4558293370 but...

Can anyone point me to a schematic of the Ls400 wiring? I want to do a quick compression check before I mount the motor on an engine stand to work on it. The starter is hiding deep in the V under the plenum and manifold and I dont want to have to strip it all off just to crank the engine over.
